Description

Technical Field

[0001] This invention relates to the field of evaporator defrosting technology, and in particular to a swing-type pipe-type cold storage defrosting device. Background Technology

[0002] Cold storage facilities often use pipe-type evaporators to reduce food dehydration. However, the temperature in and around the pipes is low, and water vapor in the air can still be captured, causing frost to form on the pipe surface. Traditional pipe-type cold storage facilities use timed manual defrosting to remove the frost layer from the pipe surface. This defrosting process is very dangerous, and frost can easily fall onto the cold storage floor and freeze. Moreover, manual defrosting is done at long intervals, usually only when the frost is thick enough. As a result, the cold storage refrigeration system operates under low-efficiency conditions for extended periods, which is not conducive to energy conservation and emission reduction. It also prevents frost from falling and causing injury to personnel and goods. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a swing-type pipe-type cold storage defrosting device, which can realize the automatic cleaning of frost in pipe-type cold storage, thereby avoiding a series of problems caused by the frost layer on the pipe surface not being cleaned for a long time, and fully improving the operating performance of pipe-type cold storage.

[0004] Therefore, the present invention provides a swing-type pipe-type cold storage defrosting device, including a snow storage box, a swing head, a snow removal head, a right moving slider, a left moving slider, a left horizontal lead screw, a right horizontal lead screw, a first right motor, a first left motor, a second right motor, a second left motor, a first right connector, a first left connector, a second right connector, a second left connector, a right suspension component, a left suspension component, a hanging rod, a synchronizing rod, a right swing motor, a left swing motor, a left suspension wire, a right suspension wire, etc.

[0005] The snow storage box is used to store the snow and ice that falls during the cleaning process, preventing the snow and ice from falling onto the cold storage floor;

[0006] The swing head is fixedly connected to the swing arms of the right swing motor and the left swing motor, and swings back and forth within a certain angle as the right swing motor and the left swing motor rotate. It has a snow removal head on it.

[0007] The snow removal head 3 is a brush structure located at the top of the swing head. When the swing head swings back and forth, the snow removal head swings along with the swing head, thereby sweeping down the frost on the pipes or the top of the cold storage.

The right horizontal lead screw cooperates with the right moving slider through the central threaded hole in the middle of the right moving slider, and its two ends are respectively connected to the first right connecting piece and the second right connecting piece. The right horizontal lead screw has a lead screw suspension groove in the middle at intervals, which is connected to the right suspension screw, thereby ensuring that the right horizontal lead screw will not undergo significant bending deformation over long distances.

[0015] The second left motor is connected to the other end of the left horizontal lead screw through the second left connector, and works with the first left motor to complete the rotation of the left horizontal lead screw;

[0016] The No. 1 right connector is used to connect the No. 1 right motor spindle and the right horizontal lead screw, so as to transmit the rotation of the No. 1 right motor spindle to the right horizontal lead screw. At the same time, the No. 1 right connector is fixed to the top of the cold storage to support the weight of the right horizontal lead screw and the No. 1 right motor.

[0017] The first left connector is used to connect the first left motor spindle and the left horizontal lead screw, so as to transmit the rotation of the first left motor spindle to the left horizontal lead screw. At the same time, the first left connector is fixed to the top of the cold storage to support the weight of the left horizontal lead screw and the first left motor.

[0018] The second right connector is used to connect the second right motor spindle and the right horizontal lead screw, so as to transmit the rotation of the second right motor spindle to the right horizontal lead screw.

[0028] This invention enables the synchronous movement of the right and left moving sliders on the right and left horizontal lead screws by operating the No. 1 left motor, the No. 1 right motor, the No. 2 left motor, and the No. 2 right motor. This drives the swing head and the cleaning head to move horizontally. At this time, the operation of the right and left swing motors will cause the swing head and the cleaning head to swing back and forth within a certain angle, realizing the defrosting operation at the contact point. The defrosted frost will fall into the frost storage tank.
