Description

Technical Field

[0001] The utility model relates to the technical field of solar vacuum tubes, in particular to an automatic cleaning device for inner and outer tubes of solar vacuum tube production. Background Art

[0002] Solar vacuum tubes, solar water heater vacuum tubes are the core components of solar water heaters. The quality of vacuum tubes directly affects the service life and performance of solar water heaters. The rapid development of the solar energy industry has also driven the development of vacuum tube companies.

[0003] After using the solar water heater for a period of time, some scale will accumulate inside the solar vacuum tube, which will cause the tube to burst. In order to ensure the stable operation of the solar water heater, the scale in the vacuum tube needs to be cleaned regularly. However, there is no equipment for cleaning vacuum tubes. The only way to dredge the pipes is by manual cleaning, which is difficult and the cleaning efficiency is very slow. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An automatic cleaning device for inner and outer tubes of solar vacuum tube production, comprising a frame, wherein symmetrically distributed side panels are arranged inside the frame, wherein a servo motor is fixedly connected to the top outer wall of one of the side panels by bolts, and the servo motor output shaft is connected to a reciprocating screw rod, a rear clamping plate is screwed to the outer wall of the reciprocating screw rod, and a front clamping plate is arranged on one side of the rear clamping plate, symmetrically distributed springs are connected between the rear clamping plate and the front clamping plate, and a rotating cylinder is installed between the other side panel and the frame;

[0007] A water pump is fixedly connected to the inner wall of one side of the frame by bolts, and a soft water pipe is connected to the water outlet of the water pump, a fixed water pipe is connected to the outer wall of one end of the soft water pipe, and a high-pressure nozzle is installed on the outer wall of one end of the fixed water pipe, a brush is bonded to the end of the outer wall of the fixed water pipe close to the high-pressure nozzle, and an electric push rod is installed on the outer wall of the connecting pipe on the fixed water pipe.

[0008] Preferably, a symmetrically distributed first guide rod is welded to an outer wall of one side of the rear clamping plate, and the first guide rod is slidably connected to the inner wall of the front clamping plate.

[0009] Preferably, a second guide rod is welded to the inner wall of the other side plate, and one end of the rear clamping plate away from the reciprocating screw rod is slidably connected to the outer wall of the second guide rod.

[0010] Preferably, a fixing frame is welded to the inner wall of one side of the frame, and the electric push rod is mounted on the inner wall of the fixing frame.

[0011] Preferably, a control box is fixedly connected to an outer wall of one side of the frame by bolts, and the control box is connected to the servo motor, the rotary cylinder, the water pump and the electric push rod by signal lines.

[0012] Preferably, the front clamping plate and the rear clamping plate are connected with equally distributed solar vacuum tubes, and the inner wall of one side of the frame is rotatably connected to a limit plate, and the bottom outer wall of the solar vacuum tube is tightly attached to the top outer wall of the limit plate.

[0013] The beneficial effects of the utility model are:

[0014] 1. The solar vacuum tube production inner and outer tube automatic cleaning device designed in this invention utilizes the elasticity of the spring. All solar vacuum tubes can be installed between the rear clamping plate and the front clamping plate at one time. When the reciprocating screw is driven by the servo motor to rotate, the solar vacuum tube will continuously move up and down in a cycle. Under the influence of inertia and gravity, scale can initially fall from the vacuum tube, thus realizing the pre-cleaning of the solar vacuum tube and reducing the difficulty of subsequent flushing.

[0015] 2. The solar vacuum tube designed herein produces an automatic cleaning device for inner and outer tubes. When the solar vacuum tube rotates to a position coaxial with the fixed water pipe, water is pumped into the fixed water pipe by a water pump. Then, as the piston rod of the electric push rod contracts, the fixed water pipe gradually approaches the vacuum tube. With the cooperation of the flushing of the high-pressure nozzle and the cleaning of the brush, all vacuum tubes are automatically cleaned synchronously, which greatly improves the cleaning efficiency and saves manpower.

[0030] Working principle: First, using the elasticity of the spring 7, all the solar vacuum tubes removed from the solar water heater are evenly placed between the rear plywood 5 and the front plywood 6, and then the servo motor 3 is used to drive the reciprocating screw 4 to rotate, and a part of the scale is thrown out of the vacuum tube by inertia and gravity, and then the rotating cylinder 8 is used to drive the solar vacuum tube to rotate to a position coaxial with the fixed water pipe 11. After the water pump 9 is connected to the water source, the water is transported to the fixed water pipe 11 through the water pump 9. Under the contraction of the piston rod of the electric push rod 14, the fixed water pipe 11 will gradually approach the vacuum tube, and the high-pressure nozzle 12 can rinse the inner wall of the vacuum tube and the brush 13 can clean up impurities.
