Description

Technical Field

[0001] This utility model belongs to the field of sewage pump processing technology, and in particular relates to a casing polishing device for sewage pump production. Background Technology

[0002] In the production process of sewage pumps, the polishing of the outer casing is a crucial step in ensuring product quality and appearance. Sewage pump casings are mostly made of metal, and after casting or machining, the surface may have burrs, scratches, and other imperfections. These need to be polished using polishing equipment to improve the smoothness and corrosion resistance of the casing, ensuring subsequent assembly and performance. Currently, the commonly used sewage pump housing polishing equipment on the market has many problems in actual operation. Most of the existing sewage pump housing polishing devices are open or semi-open structures, which will generate a large amount of metal dust and debris during the polishing process. This dust will not only pollute the workshop environment, but will also be inhaled by the operators, endangering their health. The random dispersion of dust and debris will also lead to dust accumulation on workshop equipment and ground pollution.

[0003] Therefore, developing a sewage pump housing polishing device that can improve the efficiency of debris collection and is easy to operate has become a key requirement for solving current production pain points. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a shell polishing device for the production of sewage pumps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a casing polishing device for sewage pump production, comprising a protective box for polishing the casing of a sewage pump and a polishing machine. The protective box is provided with a clamp for fixing the casing of the sewage pump. The protective box is provided with a conveying assembly for feeding the casing of the sewage pump into the processing position. The conveying assembly includes a slide rail installed on the protective box, the slide rail passing through one side wall of the protective box, a movable frame slidably connected to the slide rail, and the clamp fixedly connected to the movable frame. The protective box is provided with a collection assembly for collecting the debris generated during polishing.

[0006] Optionally, the protective box has an inlet / outlet on one side for the movable frame and the sewage pump housing thereon to enter and exit, and the movable frame has a sealing door on one side that cooperates with the inlet / outlet.

[0007] Optionally, the collection assembly includes a fan, a collection chamber is provided inside the protective box and below the slide rail, an air inlet window is provided on one side wall of the protective box, an air outlet pipe is provided at the bottom of the protective box, and the fan is installed on the air outlet pipe.

[0008] Optionally, the protective box is provided with a guide plate inside, and the guide plate is inclined.

[0009] Optionally, the top of the guide plate is provided with an outward protrusion, the interior of the protrusion is provided with an air duct, the air outlet of the air inlet window is connected to the air duct, the protrusion is provided with a plurality of air guide holes connected to the air duct, the air guide holes are arranged facing the top inclined surface of the guide plate, and the air guide holes are in the shape of a cone with a larger inner diameter and a smaller outer diameter.

[0010] Optionally, the collection chamber is provided with a retractable separation net in the middle.

[0011] In summary, the beneficial effects of this utility model are as follows: the cooperation between the sealed door on the movable frame and the inlet and outlet of the protective box can form a relatively closed processing environment during the polishing process, effectively preventing dust and debris from flying to the outside. The sliding cooperation between the slide rail and the movable frame facilitates the entry and exit of the sewage pump housing into and out of the protective box. Combined with the pull-out separation net design, the loading and unloading of materials and debris cleaning operations are made simpler. The synergistic effect of the fan, collection bin, guide plate and air guide hole and other structures forms a directional airflow circulation. After the external air enters the air duct through the air inlet window, it is accelerated and blown out through the conical air guide hole, accurately guided to the inclined surface of the guide plate, and drives the polishing debris to move towards the collection bin. Finally, it is filtered and collected by the separation net, realizing efficient gas-solid separation and improving debris cleaning efficiency. Attached Figure Description

The conveying assembly includes a slide rail 4 installed on the protective box 1. The slide rail 4 passes through one side wall of the protective box 1. A movable frame 5 is slidably connected to the slide rail 4. The clamp 3 is fixed to the movable frame 5. The protective box 1 is equipped with a collection assembly for collecting the debris generated during polishing.

[0021] Polishing machine 2 is a commonly used sewage pump housing polishing equipment on the market. Clamp 3 can be a commonly used four-jaw single-action chuck on the market. Clamp 3 is adapted to the sewage pump housing to be processed. Clamp 3 can clamp and fix the sewage pump housing to be processed. Part of the slide rail 4 is located inside the protective box 1, and the other part of the slide rail 4 is located outside the protective box 1. The moving frame 5 is slidably connected to the slide rail 4. The sewage pump housing on clamp 3 can move on the slide rail 4 with the moving frame 5, which facilitates the sewage pump housing to enter and exit the protective box 1 and facilitates the polishing treatment of the sewage pump housing.

[0022] Furthermore, the protective box 1 is provided with an inlet / outlet 6 on one side for the movable frame 5 and the sewage pump housing on it to enter and exit. The movable frame 5 is provided with a sealing door 7 on one side that cooperates with the inlet / outlet 6. The inlet / outlet 6 is located on one side of the protective box 1, which facilitates the entry and exit of the sewage pump housing. The sealing door 7 is fixed to the movable frame 5, which can keep the interior of the protective box 1 relatively closed and prevent dust generated during the polishing process from flying to the outside of the protective box 1.

[0023] Furthermore, the collection component includes a fan 8, a collection chamber 9 is provided inside the protective box 1 and below the slide rail 4, an air inlet 10 is provided on one side wall of the protective box 1, and an air outlet 11 is provided at the bottom of the protective box 1. The fan 8 is installed on the air outlet 11. The fan 8 can be purchased directly from the market. The collection chamber 9 is located inside the protective box 1. The air inlet 10 is located on one side wall of the protective box 1, and the air outlet 11 is located at the bottom of the protective box 1. The fan 8 can draw outside air into the protective box 1 through the air inlet 10 and finally discharge it from the air outlet 11. When the air circulates inside the protective box 1, it can make the dust inside the protective box 1 move in a certain direction, which facilitates the separation of polishing dust.

[0024] Furthermore, the protective box 1 is equipped with a guide plate 12 inside. The guide plate 12 is inclined and there can be multiple guide plates 12. Multiple guide plates 12 can guide the flow of gas and dust. The top surface of the guide plate 12 is inclined and the guide plate 12 is fixed to the inner wall of the protective box 1. The guide plate 12 can shield the slide rail 4 to prevent dust from falling onto the slide rail 4.

[0025] Furthermore, the top of the guide plate 12 is provided with an outward protrusion 13, and the interior of the protrusion 13 is provided with an air duct 14. The air outlet of the air inlet window 10 is connected to the air duct 14. The protrusion 13 is provided with a plurality of air guide holes 15 connected to the air duct 14. The air guide holes 15 are set towards the top slope of the guide plate 12. The air guide holes 15 are cone-shaped with a larger inner diameter and a smaller outer diameter. The protrusion 13 is integrally formed on the top of the guide plate 12. The air duct 14 is opened inside the protrusion 13. The gas in the air inlet window 10 can enter the plurality of air ducts 14. The air guide holes 15 are opened on the protrusion 13 and are connected to the air duct 14. The air guide holes 15 are set at an inclination along the slope of the guide plate 12. The air entering the air duct 14 is accelerated by the air guide holes 15 and blown onto the slide rail 4, which facilitates the collection of polishing debris.

[0026] Furthermore, the protective box 1 is equipped with a collection hopper inside, and the collection chamber 9 is equipped with a pull-out separation net 16 in the middle and below the collection hopper. The collection hopper is fixed inside the protective box 1 and is located below the slide rail 4. The separation net 16 is slidably connected to the middle of the collection chamber 9. A pull-out door is provided on one side of the separation net 16. When the pull-out door is closed, it can be sealed with the protective box 1. The separation net 16 can be pulled out from the protective box 1 to facilitate the removal of debris from the separation net 16.

[0027] The specific working principle is as follows: In use, first use clamp 3 to fix the sewage pump housing to be processed, then move the moving frame 5 into the protective box 1 until the sealing door 7 completely blocks the inlet and outlet 6. Then use polishing machine 2 to polish the sewage pump housing. After polishing, move the moving frame 5 to the outside of the slide rail 4 and remove the polished sewage pump housing.

[0028] During the polishing process of the sewage pump casing, the blower 8 can draw in external air through the air inlet window 10 into multiple air ducts 14. The airflow in the air ducts 14 is accelerated by the air guide hole 15 and then blown out. The debris generated during the polishing process moves in the direction under the action of the airflow. The debris generated during polishing will be collected together through the collecting hopper and fall onto the separation screen 16. The airflow passes through the separation screen 16 and is discharged from the air outlet pipe 11. When the debris on the separation screen 16 reaches a certain amount, the separation screen 16 can be pulled out for cleaning.

[0029] More specifically, the protective box 1 is equipped with a telescopic rod 17 connected to the movable frame 5 inside. The telescopic rod 17 is equipped with a corrugated protective tube 18 on the outside. The telescopic rod 17 is a hydraulic rod that can be purchased directly from the market. The corrugated protective tube 18 is located on the outside of the telescopic rod 17 and can protect the telescopic rod 17 to prevent the debris generated during the polishing process from entering the interior of the telescopic rod 17.

[0030] More specifically, the air inlet window 10 is equipped with a filter screen 19, which is located inside the air inlet window 10 and can filter the gas entering the protective box 1 to avoid clogging of the air duct.
