DETAILED DESCRIPTION

[0019] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0020] like Figure 1-Figure 4 As shown, the present embodiment provides a PVC pipe production cooling device, including a shell 1, a C-tube 2 is rotated inside the shell 1, and racks 3 are evenly arranged on the outside of the C-tube 2. A motor 4 is installed on the top of the shell 1, and a reciprocating screw 5 is fixed to the output shaft of the motor 4. A sliding tube 6 is slidably arranged on the outside of the reciprocating screw 5. A slider 7 is fixed inside the sliding tube 6, and the slider 7 is slidably connected to the outside of the reciprocating screw 5. A tooth plate 8 is fixed on one side of the sliding tube 6, and the tooth plate 8 is meshed with the rack 3, and the tooth plate 8 is slidably connected to the inner wall of the shell 1. A water pump 9 is installed on the top of the shell 1, and a water inlet pipe 10 is fixed to the water inlet end of the water pump 9, and a hose 11 is symmetrically arranged at the water outlet end of the water pump 9, and an annular nozzle 12 is fixed at one end of the hose 11, and the annular nozzle 12 is fixed to the inner wall of the C-tube 2, a filtering component 13 is arranged inside the shell 1, and a supporting component 14 is arranged inside the C-tube 2.

[0021] In this embodiment, if Figure 1 As shown, the filter assembly 13 includes a partition 15 and a connecting rod 19. The partition 15 is located on the inner side wall of the housing 1. A drain port 16 is opened on the top of the partition 15. A baffle 17 is fixed to the bottom of the partition 15. A filter screen 18 is fixed to one side of the baffle 17. The connecting rod 19 is located at the bottom end of the reciprocating screw 5. A brush plate 20 is symmetrically arranged at the bottom of the connecting rod 19. The water sprayed by the annular nozzle 12 flows to the surface of the baffle 17 through the drain port 16, and the water flows through the filter screen 18 and flows to the housing through the mesh of the filter screen 18. 1, and impurities are accumulated on the surface of the filter screen 18. At the same time, the reciprocating screw 5 rotates to drive the connecting rod 19 and the brush plate 20 to rotate. When the brush plate 20 rotates, it brushes the impurities on the surface of the filter screen 18 to prevent the mesh of the filter screen 18 from being blocked, so as to filter the cooling water. At the same time, the filter screen 18 for filtering the cooling water can be cleaned by the rotating brush plate 20, so as to facilitate the dredging of the mesh of the filter screen 18 and facilitate the rapid passage of the filtered water, thereby improving the filtering efficiency of the circulating water and meeting the use needs of people.

[0022] In this embodiment, if Figure 1 , 4 As shown, the support assembly 14 includes a semicircular tube 21 and a roller 22. The semicircular tube 21 is arranged on the inner bottom wall of the C-shaped tube 2. The rollers 22 are evenly arranged inside the semicircular tube 21, and the rollers 22 are all rotatably connected to the semicircular tube 21. When the pipe passes through the shell 1, the bottom of the pipe is supported by the semicircular tube 21 and the rollers 22, which support the pipe. When the C-shaped tube 2 rotates, the semicircular tube 21 and the rollers 22 are driven to rotate. At the same time, multiple groups of rollers 22 roll and rub against the surface of the pipe, and still support the pipe, preventing the PVC pipe from easily deforming during cooling. At the same time, the supporting part rolls and rubs against the surface of the pipe, which is not easy to wear the pipe.

[0023] In this embodiment, if Figure 1 As shown, the filter screen 18 is tiltedly arranged on one side of the baffle 17, and the filter screen 18 is fixedly connected to the inner wall of the housing 1. The tilted filter screen 18 facilitates the flow of impurities and makes them accumulate at the lowest point for easy cleaning.

[0024] In this embodiment, if Figure 1 As shown, a sewage outlet is provided on one side of the shell 1, and a material guide plate is provided on one side of the shell 1, and the sewage outlet is convenient for cleaning and discharging impurities.

[0025] In this embodiment, if Figure 1 As shown, a protective ring is fixed on the top of the partition 15, and a baffle 17 is tilted inside the shell 1. The protective ring prevents water from flowing to the surface of the partition 15, so that the cooling water is concentrated in the drain port 16 and enters the bottom of the partition 15.

[0026] like Figure 1-Figure 4 As shown, the working process of the cooling device for producing PVC pipes provided in this embodiment is as follows:

[0027] Step 1: When the PVC pipe enters the C-shaped pipe 2, the water pump 9 and the motor 4 are started. The water pump 9 pumps the water on the bottom wall of the shell 1 into the hose 11 through the water inlet pipe 10, and sprays it on the surface of the pipe through the annular nozzle 12. The motor 4 drives the reciprocating screw 5 to rotate. The reciprocating screw 5 drives the sliding pipe 6 to move up and down on the reciprocating screw 5 through the slider 7, and then the sliding pipe 6 drives the tooth plate 8 to move up and down. The tooth plate 8 drives the C-shaped pipe 2 to rotate clockwise and counterclockwise through the rack 3, so that the annular nozzle 12 inside the C-shaped pipe 2 rotates back and forth and sprays water on the pipe comprehensively to complete the cooling work;

[0028] Step 2: When the pipe passes through the shell 1, the bottom of the pipe is supported by the semicircular tube 21 and the roller 22, which supports the pipe. When the C-shaped tube 2 rotates, the semicircular tube 21 and the roller 22 are driven to rotate. At the same time, the multiple groups of rollers 22 roll and rub against the surface of the pipe, while still supporting the pipe.

[0029] Step 3: The water sprayed by the annular nozzle 12 flows to the surface of the baffle 17 through the drain port 16, and the water flows through the filter screen 18 and flows to the inner bottom wall of the shell 1 through the mesh holes of the filter screen 18. Impurities accumulate on the surface of the filter screen 18. At the same time, the reciprocating screw 5 rotates to drive the connecting rod 19 and the brush plate 20 to rotate. When the brush plate 20 rotates, it brushes the impurities on the surface of the filter screen 18 to prevent the mesh holes of the filter screen 18 from being blocked.

[0030] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
