Description

one

The invention relates to construction equipment and can be used to paint both the internal and external surfaces of industrial and residential buildings and structures, ship hulls, etc., as well as for washing and spraying glazed and other surfaces.

A spray gun is known, which includes scattering devices stuck on a fishing tackle or pen, a device for regulating the supply of compounds to spraying devices, hoses for supplying stoppers, and also containers for compositions and devices for pumping them into system 1.

However, such a device creates a short effective length of the jet, i.e., it delivers paint to the treated surface just a distance of 0.2-0.3 m from the spray gun, therefore special surface treatment is required for surface treatment; and other devices.

In addition, the work performed requires a lot of manual labor, which has high labor intensity and cost; The working conditions are harmful and dangerous to health, as the workers are in direct contact with the area of divergence of the trains and work on stairs, scaffolding, etc.

The prototin of the invention is a liquid dispenser, comprising a liquid scavenger, an injection means thereof, an axial fan mounted in

cylindrical housing with inlet diffuser 2.

However, in this device, the kicker is located directly in the body, which increases the jet turbulence,

creates additional resistance, resulting in a jet with a maximum lateral expansion angle, minimum speed and long range.

In order to increase productivity and

In order to increase the range of the jet, a device is proposed in which the cylindrical body is provided at the outlet with a confuser and a grille, and the liquid dispenser is mounted coaxially with the cylindrical body behind the confuser cut.

The cylindrical body is mounted on a vertical stand with the possibility of rotation in the vertical and horizontal planes. In addition, the sprayer is equipped with a conical nozzle.

Claims (2)

. FIG. 1 shows the proposed device, a general view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a view along arrow B in FIG. 1. The device contains a sprayer 1 liquid (nozzle or gun) with a hollow conical nozzle 2 mounted on a metal fishing rod 3. The fishing rod, in turn, is attached to a cylindrical body 4. The fishing rod 3 is connected to the regulator 5 to supply sprayed liquids. The supply of fluid is carried out under pressure through the hose 6 with the help of a compressor or other device (not shown in the drawing). The housing 4 is provided with a diffuser 7 at the inlet, and a confuser 8 and a spraying grinder 9 at the outlet. In the housing 4 an axial fan 10 is mounted with a fairing (not shown) and an electric motor 11. A hole 12 is attached to the bottom of the housing 4 (not indicated in the drawing), with the help of this plug, the axis 13 and the bolt 14, the housing is fixed to the figured plug 15. The second support point of the housing with the fan is the hinge 16 connected by a screw 17 to a worm gearbox and reversing device. electromotor 18 mounted on two lanes 19 rigidly fixed in the upper part of the plug 15. The reversible electromotor 18 through the screw gear draws in or pushes the screw 17 and provides rotation of the housing with a fan in a vertical plane. The vertical stand consists of four pipes 20, theyraun1, ikhs on round plates. The pipes 20 in the upper part are rigidly connected to the ball bearing box 21, in the middle part by a ring 22 and in the lower part by a platform 23 on which a reversible electric motor 24 with a gearbox and a worm screw is placed. The top fork 15 is supported on the bearing 21, and the lower part, which can be made of a pipe, is inserted into the support 25 and rests on a platform 23 having a hole in the center with a sleeve (not indicated in the drawing). the lower end of the plug 15 is inserted and secured with a washer (not shown in the drawing) and nuts 26 to ensure the free rotation of the plug 15. A worm wheel 27 is mounted on the bottom of the plug 15. A reversible electric motor 24 with a gearbox and a worm screw rotates the worm gear wheel 27 and provides turn from fork 15 and secured thereon with the fan casing in a horizontal plane. The device works as follows. Fan 10 is started up; then scatter fluid is fed to the sprayer. The long-range air jet created by the fan 10 delivers the sprayed liquid to the surface to be treated. The air jet flowing at high speed through the conical nozzle 2 creates a reduced pressure area behind it, which increases the performance of the sprayer. The housing 4 with a fan and a sprayer is rotated to either side during remote control by turning on and off reversing electric motors 18 and 24. The device is to be mounted on mobile platforms, cars, etc., along with a compressor, a container for dispensers and pump for their submission. The proposed device allows hundreds of times to increase the effective length, as well as the diameter of the jet of dyeing or other compositions when painting, washing or spraying any surfaces and correspondingly to increase labor productivity, improve working conditions, ensure a significant reduction in the cost of these works and reduce their time. fulfillment. Claim 1. A liquid dispenser containing a liquid dispenser, a means for injecting it, an axial fan mounted in a cylindrical housing with a diffuser inlet, characterized in that, in order to increase the capacity and increase the range of the liquid jet, the cylindrical housing output by the confuser and the spreading grid, and the liquid sprayer is mounted coaxially with the cylindrical body behind the cut confuso2. The device, but item 1, is the same, with a cylindrical body mounted on a vertical stand that can be rotated in a vertical and horizontal position. 3. The device on n. 1, characterized in that the sprayer is provided with a conical nozzle. Sources of information taken into account in the examination 1. USSR author's certificate №86700, cl.
