Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular to an interception device for wastewater treatment in cogeneration plants. Background Technology

[0002] Wastewater generated by cogeneration includes ash flushing water, dust removal water, industrial wastewater, domestic sewage, and desulfurization wastewater. It is necessary to use interception devices to intercept large suspended particles in the wastewater to prevent clogging of subsequent equipment. However, existing interception devices are not convenient for quickly discharging the intercepted large suspended particles during use, causing large suspended particles to clog the interception wire mesh and reducing the device's interception effect on cogeneration wastewater.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN221846328U) entitled "An Interception Device for Wastewater Treatment in a Wastewater Treatment Tank." This device includes an interception grid installed inside the wastewater tank. An installation plate is mounted on the top of the wastewater tank, and a cleaning mechanism for cleaning the interception grid is installed on the installation plate. Two symmetrically distributed vertical blocks are fixedly connected to the bottom of the installation plate and inserted into slots at the top of the wastewater tank. The cleaning mechanism includes a cleaning plate at the bottom of the installation plate, with a cleaning brush fixed to one end. A cylinder is fixedly mounted on the top of the installation plate, and the cylinder's push rod passes through the installation plate and is fixedly connected to the top of the cleaning plate. A collection hole is provided on the cleaning plate, and a collection box is located at the bottom of the cleaning plate. This wastewater treatment interception device solves the problem that existing interception devices become clogged as debris accumulates, leading to reduced wastewater treatment efficiency. However, this device is not convenient for quickly discharging large suspended particles, easily causing the interception wire mesh to become clogged, thus reducing the device's interception effect on cogeneration wastewater. Utility Model Content

[0004] The purpose of this invention is to provide an interception device for wastewater treatment in combined heat and power plants, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an interception device for wastewater treatment in combined heat and power plants, comprising:

[0006] A wastewater treatment tank for combined heat and power (CHP) wastewater treatment, with two mounting ears connected to each of the two outer side walls of the wastewater tank, and an interception component for CHP wastewater treatment installed on the inner side wall of the wastewater tank.

[0007] A cleaning assembly for wastewater treatment in combined heat and power plants includes a mounting plate and an electric push rod. The electric push rod is embedded in the top surface of the mounting plate, and the moving end of the electric push rod is connected to a support plate. A cleaning box is connected to the bottom surface of the support plate, and a scraper for removing debris that clogs the interception components is connected to the top surface of the cleaning box. A linear motor is mounted on the side of the cleaning box, and a connecting plate is connected to the moving part of the linear motor. A cleaning plate is connected to the bottom surface of the connecting plate, and four connecting rods are connected to both sides of the cleaning plate. A baffle plate is connected to the end face of the four connecting rods.

[0008] Preferably, mounting brackets are connected to both ends of the mounting plate, and the bottom of the mounting brackets is connected to two mounting ears by bolts.

[0009] Preferably, the inner sidewall of the cleaning box is slidably connected to the cleaning plate and two shielding plates respectively, and the two end faces of the cleaning box are provided with through slots for the shielding plates to pass through.

[0010] Preferably, the interception assembly includes two support frames and a sliding rod, with the bottom surfaces of both support frames being connected and fixed to the sewage tank.

[0011] Preferably, the inner wall of the support frame is connected to the slide rod, and a sliding plate is slidably connected to the side of the slide rod.

[0012] Preferably, the two sliding plates are connected to a fixed frame on adjacent sides, and the bottom surface of the fixed frame is connected to an interception frame adapted to the inner wall of the sewage tank.

[0013] Preferably, the inner wall of the interceptor frame is connected to a steel wire filter for intercepting wastewater from combined heat and power plants, and an abutment plate is slidably connected to the bottom surface of the interceptor frame.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This interception device for cogeneration wastewater treatment addresses the need to intercept large suspended solids in the wastewater generated by cogeneration to prevent clogging of subsequent treatment equipment. Larger suspended solids easily clog the wire mesh filter that provides the interception function. Often, a scraper is used to remove the large suspended solids that clog the filter. An electric push rod provides power, and with the support plate connected, the scraper moves vertically to clean the large suspended solids adhering to the surface of the wire mesh filter, causing the large suspended solids to fall into the collection box. After moving to a designated height, a linear motor is activated, and the moving part of the linear motor moves laterally. During the transmission process, the cleaning plate, two baffle plates, and four connecting rods move laterally, quickly transferring the large suspended solids collected in the cleaning box into the collection box, thus enhancing the device's interception effect on cogeneration wastewater.

[0017] This interception device for cogeneration wastewater treatment includes interception components designed to intercept large suspended solids in the cogeneration wastewater. An interception frame provides support and fixation for the wire mesh filter. With the connection provided by the fixing frame, the sliding plate can move along the path of the sliding rod, adjusting the lateral position of the wire mesh filter during transmission to prevent loose contact between the wire mesh filter and the scraper, which would affect the scraper's cleaning effect on large suspended solids clogging the wire mesh surface and improve the structural stability of the device's components. Tightening bolts are used to fix the position of the sliding plate, preventing the wire mesh filter from shaking or shifting during use. Attached Figure Description

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0031] Please see Figures 1 to 7 An interception device for wastewater treatment in combined heat and power plants, in this embodiment including:

[0032] Wastewater treatment tank 1 for cogeneration wastewater treatment. Two mounting ears 2 are connected to the two outer walls of wastewater tank 1. An interception component 15 for cogeneration wastewater treatment is provided on the inner wall of wastewater tank 1 so that the interception component 15 can intercept large suspended particles in cogeneration wastewater and prevent subsequent equipment from being blocked by large suspended particles.

[0033] A cleaning component 3 for wastewater treatment in a combined heat and power plant includes a mounting plate 5 and an electric push rod 6. The electric push rod 6 is embedded in the top surface of the mounting plate 5, which has a through groove. The inner wall of the through groove is fixed to the fixed end of the electric push rod 6 by bolts. The moving end of the electric push rod 6 is connected to a support plate 7, which is inverted U-shaped. A cleaning box 8 is connected to the bottom surface of the support plate 7. The top of the cleaning box 8 has an opening, and a scraper 9 is connected to the top surface of the cleaning box 8 to scrape away debris from the blockage interception component 15. During vertical movement, the scraper 9 can scrape away large suspended particles from the blockage interception component 15. Large suspended particles are collected in the cleaning tank 8. The bottom wall of the cleaning tank 8 has several through holes for sewage to flow out. Large suspended particles are collected in the cleaning tank 8, while sewage flows out through the through holes of the cleaning tank 8. A linear motor 10 is installed on the side of the cleaning tank 8. The fixed end of the linear motor 10 is connected to the cleaning tank 8 by bolts. The moving part of the linear motor 10 is connected to a connecting plate 11. The connecting plate 11 is in the shape of an inverted U. The bottom surface of the connecting plate 11 is connected to a cleaning plate 12. Four connecting rods 13 are connected to both sides of the cleaning plate 12. The end faces of the four connecting rods 13 are connected to a baffle plate 14.

[0034] Mounting brackets 4 are connected to both ends of mounting plate 5. Mounting brackets 4 are inverted U-shapes. The bottom of mounting brackets 4 are connected to two mounting ears 2 by bolts. The inner sidewalls of cleaning box 8 are slidably connected to cleaning plate 12 and two baffle plates 14 respectively. The size of cleaning plate 12 is the same as that of baffle plate 14. When cleaning box 8 is moved to the top, the bottom surface of cleaning box 8 is flush with the top surface of sewage tank 1. The two ends of cleaning box 8 are provided with through slots for baffle plates 14 to pass through. Interception assembly 15 includes two support frames 21 and sliding rods 20. The bottom surfaces of the two support frames 21 are fixedly connected to sewage tank 1. The inner wall of support frame 21 is connected to sliding rod 20. The side of sliding rod 20 is slidably connected to sliding lugs. The slide plate 19, and the inner top and bottom walls of the support frame 21 are in sliding friction contact with the slide plate 19. The two slide plates 19 are connected to the adjacent sides of the U-shaped fixing frame 18. The bottom surface of the fixing frame 18 is connected to the interception frame 16 adapted to the inner wall of the sewage tank 1. The inner side wall of the interception frame 16 is connected to the wire mesh 17 for intercepting cogeneration sewage. The bottom surface of the interception frame 16 is slidably connected to the abutment plate 24. The bottom surface and both sides of the abutment plate 24 are connected and fixed to the sewage tank 1. The side of the slide plate 19 away from the fixing frame 18 is threaded with a tightening bolt 22 for tightening the slide rod 20. The two sides of the sewage tank 1 are connected to the collection box 23. The flow direction of the cogeneration sewage in the sewage tank 1 is from left to right.

[0035] In order to intercept cogeneration wastewater, an interception frame 16 is installed to support a wire mesh filter 17. The two outer walls of the interception frame 16 are slidably connected to the two inner walls of the wastewater tank 1, so that when the cogeneration wastewater flowing in the wastewater tank 1 passes through the wire mesh filter 17, large suspended particles in the cogeneration wastewater are intercepted by the wire mesh filter 17, preventing large suspended particles in the cogeneration wastewater from clogging downstream equipment.

[0036] To quickly remove large suspended particles, an electric push rod 6 provides power, causing the moving end of the electric push rod 6 to move the support plate 7 vertically. During the transmission process, the scraper 9 moves vertically to scrape off the large suspended particles clogging the surface of the wire mesh 17. As the scraper 9 moves from bottom to top, the scraped large suspended particles fall into the cleaning box 8. When the cleaning box 8 moves to the top, the linear motor 10 is activated. During the movement of the moving part of the linear motor 10, the connecting plate 11 moves. During the transmission process, the cleaning plate 12, the two baffle plates 14, and the four connecting rods 13 move laterally, causing the large suspended particles collected in the cleaning box 8 to fall into the inner cavity of the two collection boxes 23. This achieves rapid discharge and cleaning of large suspended particles, improving the interception effect of the device on cogeneration wastewater.

[0037] To enhance the scraping effect on large suspended particles clogging the wire mesh 17, the two slide plates 19 are moved laterally along the path of the slide bar 20. With the connection of the fixed frame 18, the interceptor frame 16 and the two slide plates 19 move synchronously and in the same direction, so that the wire mesh 17 moves towards the scraper 9, achieving close contact between the wire mesh 17 and the scraper 9, and enhancing the scraping effect on large suspended particles clogging the surface of the wire mesh 17.

[0038] The electric actuator 6 and the linear motor 10 are existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0039] Working principle

[0040] In this combined heat and power (CHP) wastewater treatment interception device, when in use, the CHP wastewater in the wastewater tank 1 is intercepted by a wire mesh filter 17 to remove large suspended solids. The electric push rod 6 is activated, and its moving end moves. With the support plate 7 connected, the cleaning box 8 and the scraper 9 move vertically. The scraper 9 removes the large suspended solids clogging the surface of the wire mesh filter 17, causing the large suspended solids to fall into the inner cavity of the cleaning box 8. The linear motor 10 is activated, and with the connection plate 11 connected, the cleaning plate 12 and the baffle plate 14 move during the transmission process, discharging the large suspended solids into the collection box 23.

[0041] The two slide plates 19 are moved along the path of the slide bar 20 respectively. With the connection of the fixed frame 18, the interceptor frame 16 and the wire mesh 17 move synchronously and in the same direction, so that the wire mesh 17 is in close contact with the scraper 9. The position of the slide plate 19 is fixed by the tightening bolt 22, which enhances the effect of the scraper 9 in removing large particulate suspended matter clogging the surface of the wire mesh 17.
