Description

A device for liquid recovery in hose

technical field

The invention relates to the technical field of liquid recovery, in particular to a device for liquid recovery in hoses.

Background technique

In the outdoor mobile refrigeration equipment, due to the limitation of equipment conditions, the refrigeration vehicle and the equipment to be refrigerated are not on the same vehicle, and the cooling liquid is circulated through the fire hose connecting the two. When the equipment is withdrawn, the fire hose There are several ways to recover the coolant in the cooling system: one is to withdraw it with a water pump, because the pipe wall of the fire hose is soft, and the water pump will cause the fire hose to be partially flattened and the cooling water cannot be completely recovered. The second is to pour the cooling liquid in the fire water bag into the bucket, and then pour the cooling liquid in the bucket into the water tank. This method is time-consuming and labor-intensive, and it is easy to mix the coolant with impurities, which will affect the work of the refrigerator. If the coolant in the fire hose is completely drained, it will cause a lot of waste. Therefore, it is imperative to provide a device that can quickly recover the cooling liquid remaining in the fire hose to the water tank for recirculation when the equipment is withdrawn after the refrigeration work is completed.

The device for liquid recovery in the hose of the present invention also includes a left baffle and a right baffle, one end of which is inserted at both ends of the movable shaft, and the other end is sleeved at both ends of the fixed shaft; the above-mentioned left baffle and right baffle A waist-shaped hole is arranged on one end of the fixed shaft, and a U-shaped hole is arranged on one end inserted into the movable shaft.

The right end of the movable shaft is provided with a U-shaped opening perpendicular to the axis, and is sleeved on one end of the right movable support rod through the U-shaped opening.

A cap nut is installed on the upper end of the left movable strut, the other end of the left movable strut is riveted on the U-shaped bracket through the first rivet and can rotate around the axial direction of the first rivet, the right movable strut The other end is riveted on the U-shaped bracket through the second rivet and can rotate around the axial direction of the second rivet.

The device of the present invention relies on the power of the hand to pull and complete the work. When working, loosen the lock nut, lift the movable shaft to a certain angle, and then rotate the movable shaft around the left movable bracket. At this time, insert a hose filled with liquid between the fixed roller and the movable roller to rotate the movable shaft Return to the original position, adjust the hose between the movable roller and the fixed roller, press the movable roller onto the hose, put the left and right screw rods into the U-shaped grooves of the left and right supports, manually tighten the left and right lock nuts until the fixed roller and the fixed roller The movable roller presses the hose tightly, and then pulls the U-shaped bracket beam along the direction of the hose to squeeze the liquid in the hose back into the water tank. When the hose is pulled to the rearmost end, the locking nut is loosened, the movable shaft is lifted and rotated at a certain angle, and the device can be removed from the hose to complete the liquid recovery work in a hose. Since the fixed roller and the movable roller roll on the hose when they are working, the wear of the roller on the hose is reduced, and the operator saves more effort.

The beneficial effects of the present invention are: the use of two roller structures similar to the working principle of the gear pump to squeeze the liquid in the hose has the advantages of simple structure, reliable operation, no need for electricity, low cost, and time-saving and labor-saving advantages; the device can It is used in any industry where the liquid in the hose needs to be recovered, and has high practical value.
