Description

Technical Field

[0001] This utility model relates to the field of sewage discharge equipment technology, and in particular to an automatic sewage discharge equipment for painting workshops. Background Technology

[0002] In automotive painting workshops, the electrophoresis process is a core step in ensuring the corrosion resistance of the car body. It requires a clean surface to form a uniform primer layer. Therefore, most car manufacturers have an electrophoresis process in their existing painting workshops. Before entering the electrophoresis pool, the car body undergoes a deep cleaning process, which is a pretreatment. This pretreatment process generates a large amount of wastewater, which gradually accumulates in a wastewater pit as the car body is transported. Currently, the industry commonly uses a method of "manually controlled water pump drainage," but this method has certain drawbacks: firstly, manual operation has a response delay, which may lead to wastewater overflow and safety hazards due to delayed drainage; secondly, manual monitoring requires continuous labor costs and is prone to operational errors, increasing production costs and reducing the stability and efficiency of wastewater discharge operations. Therefore, we propose an automatic wastewater discharge device for painting workshops to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide an automatic sewage discharge device for painting workshops to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic sewage discharge device for a painting workshop, comprising a sewage pit, the bottom of which is connected to a filter cylinder via a first drain pipe, a drain pump motor installed outside the first drain pipe, a mounting frame fixed inside the sewage pit, a float-type level gauge installed on the mounting frame, the float-type level gauge comprising a guide tube mounted on the mounting frame and a magnetic float sleeved outside the guide tube, a control box installed at the top of the sewage pit, a filter chamber located at the end of the filter cylinder facing the drain pump motor, a filtration chamber located at the side of the filter cylinder away from the drain pump motor, a second drain pipe installed at the lower end of the filtration chamber, an isolation seat fixed between the filter chamber and the filtration chamber, a filter plate installed inside the isolation seat, and a handle installed at the top of the filter plate.

[0005] As an improved technical solution, rotating seats are installed on both sides of the top of the isolation seat, and rotating plates are rotatably connected to the outside of both sets of rotating seats. Both sets of rotating plates rotate to the top of the isolation seat.

[0006] As an improved technical solution, the control box is electrically connected to the float-type level gauge and the drain pump motor.

[0007] As an improved technical solution, the filter plate is a detachable multi-layer filter structure, including a coarse filter layer and a fine filter layer.

[0008] As an improved technical solution, a one-way valve is provided at the outlet of the second drain pipe.

[0009] As an improved technical solution, the rotating plate is provided with a sealing strip, and the outer wall of the bottom end of the rotating plate is in contact with the outer wall of the top end of the filter plate.

[0010] As an improved technical solution, the outer wall of the handle is subjected to a grinding process.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are:

[0012] I. This utility model installs a float-type level gauge inside a sewage pit and a second drain pipe outside the pit. The magnetic float on the level gauge rises and falls with the liquid level. When the liquid level reaches a designated height, the magnetic float triggers an internal sensor, transmitting a signal to the control box. This automatically starts the drain pump motor, allowing sewage from the pit to be pumped through the first drain pipe into the filter cartridge. After initial filtration in the filter chamber, the sewage passes through the filter plate into the filtration chamber and is finally discharged through the second drain pipe. This achieves fully automatic level detection and drainage, reducing manual intervention, improving equipment safety, and effectively separating impurities through the filtration structure, protecting downstream pipelines and equipment. Furthermore, the overall structure is compact and suitable for the confined spaces of a painting workshop.

[0013] II. This utility model has two sets of rotatable rotating plates installed at the top of the isolation seat. The two sets of rotating plates can be turned to rotate along the rotating seat, allowing the two sets of rotating plates to quickly rotate away from the top of the isolation seat and quickly release the limiting effect of the two sets of rotating plates on the filter plate inside the isolation seat. This facilitates the disassembly and replacement of the filter plate and improves the convenience of filter plate disassembly. Attached Figure Description

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0025] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, an automatic sewage discharge device for a painting workshop includes a sewage pit 1. The bottom of the sewage pit 1 is connected to a filter cylinder 9 through a first drain pipe 2. A drain pump motor 8 is installed outside the first drain pipe 2. An installation frame plate 3 is fixed inside the sewage pit 1. A float-type liquid level gauge 4 is installed on the installation frame plate 3. The float-type liquid level gauge 4 includes a conduit 5 installed on the installation frame plate 3 and a magnetic float 6 sleeved outside the conduit 5. A control box 7 is installed at the top of the sewage pit 1. A filter chamber 10 is provided at the end of the filter cylinder 9 facing the drain pump motor 8. A filtration chamber 11 is provided on the side of the filter cylinder 9 away from the drain pump motor 8. A second drain pipe 12 is installed at the lower end of the filtration chamber 11. An isolation seat 13 is fixed between the filter chamber 10 and the filtration chamber 11. A filter plate 14 is installed inside the isolation seat 13. A handle 15 is installed at the top of the filter plate 14.

[0026] By installing a float-type level gauge 4 inside the sewage pit 1 and a second drain pipe 12 outside the sewage pit 1, the magnetic float 6 on the float-type level gauge 4 floats up and down with the liquid level. When the liquid level reaches a specified height, the magnetic float 6 triggers the internal sensor, which transmits a signal to the control box 7, thereby automatically starting the drain pump motor 8. The sewage in the sewage pit 1 is then pumped by the drain pump motor 8 through the first drain pipe 2 to the filter cartridge 9. After preliminary filtration in the filter chamber 10, the sewage enters the filtration chamber 11 through the filter plate 14 and is finally discharged through the second drain pipe 12. This achieves fully automatic liquid level detection and drainage, reduces manual intervention, and effectively separates impurities through the filtration structure, protecting subsequent pipelines and equipment.

[0027] In other embodiments, rotating seats 16 are installed on both sides of the top of the isolation seat 13, and rotating plates 17 are rotatably connected to the outside of the two sets of rotating seats 16. The two sets of rotating plates 17 are rotated to the top of the isolation seat 13.

[0028] By installing two sets of rotatable rotating plates 17 at the top of the isolation seat 13, the two sets of rotating plates 17 can be moved to rotate along the rotating seat 16, allowing the two sets of rotating plates 17 to quickly rotate away from the top of the isolation seat 13, and allowing the two sets of rotating plates 17 to quickly release the limiting effect on the filter plate 14 inside the isolation seat 13, thereby facilitating the disassembly and replacement of the filter plate 14 and improving the convenience of disassembling the filter plate 14.

[0029] In other embodiments, the control box 7 is electrically connected to the float level gauge 4 and the drain pump motor 8;

[0030] This design allows the control box 7 to receive high and low liquid level signals from the float-type level gauge 4, thereby automatically controlling the start and stop of the drainage pump motor 8.

[0031] In other embodiments, the filter plate 14 is a detachable multi-layer filter structure, including a coarse filter layer and a fine filter layer;

[0032] This design allows wastewater to pass through the coarse and fine filter layers in the filter plate 14 in succession, improving filtration efficiency and service life, enhancing filtration effect, and adapting to complex components such as particulate matter and paint residue in paint workshop wastewater.

[0033] In other embodiments, a check valve is provided at the outlet of the second drain pipe 12;

[0034] This design allows the one-way valve at the second drain pipe 12 to automatically close when the drain pump motor 8 stops working, preventing filtered wastewater from flowing back into the filter cartridge 9, avoiding secondary pollution, and improving drainage reliability.

[0035] In other embodiments, the rotating plate 17 is provided with a sealing strip, and the outer wall of the bottom end of the rotating plate 17 is in contact with the outer wall of the top end of the filter plate 14.

[0036] This design allows the rotating plate 17 to provide a stable limiting effect on the filter plate 14, preventing the filter plate 14 from shaking during use.

[0037] In other embodiments, the outer wall of the handle 15 is polished.

[0038] This design effectively increases the friction between the handle 15 and the user's hand, making it easier to pull the handle 15 effectively.

[0039] This utility model provides an automatic sewage discharge device for a painting workshop, the specific working principle of which is as follows:

[0040] Wastewater collection: Wastewater from vehicle body washing is allowed to flow into wastewater pit 1 and accumulate.

[0041] Liquid level detection: The magnetic float 6 on the float-type liquid level gauge 4 moves up and down with the liquid level, triggering the internal sensor and transmitting the signal to the control box 7.

[0042] Automatic drainage: When the liquid level reaches the set height, the control box 7 starts the drainage pump motor 8 to pump the sewage into the filter cartridge 9 through the first drain pipe 2.

[0043] Two-stage filtration: Wastewater first enters the filtration chamber 10 and is filtered step by step through the coarse and fine filtration layers of the filter plate 14. Solid impurities are intercepted, and clean water enters the filtration chamber 11.

[0044] Clean water discharge: The filtered clean water is discharged from the system through the second drain pipe 12.

[0045] Maintenance and replacement: When the filter plate 14 is clogged, the isolation seat 13 can be quickly opened through the rotating plate 17 to remove the filter plate 14 for cleaning or replacement.

[0046] Automatic stop: When the liquid level drops to a low level, the control box 7 receives a signal and stops the drain pump motor 8, completing one drain cycle.
