Description

Technical Field

[0001] This utility model relates to the technical field of wastewater pretreatment equipment, and in particular to a wastewater pretreatment equipment. Background Technology

[0002] Wastewater pretreatment equipment refers to a series of devices located at the initial stage of the wastewater treatment process. Their main function is to perform preliminary treatment and conditioning of the wastewater, preparing it for subsequent advanced treatment. This equipment removes impurities from the water through physical or chemical means, ensuring that the wastewater can smoothly enter the subsequent treatment processes.

[0003] In wastewater pretreatment, filters are typically used to remove impurities from the wastewater. However, during filtration, these impurities tend to accumulate on the filters, causing blockages and affecting filtration efficiency. Therefore, effectively and promptly cleaning and collecting these filtered impurities is a crucial issue that needs to be addressed in the design of wastewater pretreatment equipment. Utility Model Content

[0004] This invention provides a wastewater pretreatment device to solve the problem of impurities accumulating on the filter screen and causing filter clogging.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a wastewater pretreatment device, including a wastewater treatment shell, and further comprising:

[0007] The filter structure is installed inside the wastewater treatment shell.

[0008] The cleaning structure is located on the filter structure.

[0009] The tapping structure is located at the bottom of the filter structure and taps the cleaning structure to clean it.

[0010] The collection structure is located below the filter structure.

[0011] Preferably, four support columns are fixedly connected to the bottom side wall of the sewage treatment shell, the bottom of the four support columns are fixedly connected to the support shell, a drain pipe is fixedly connected to one side wall of the support shell, and an inlet pipe is fixedly connected to the top side wall of the sewage treatment shell.

[0012] In this technical solution, wastewater is introduced into the wastewater treatment shell through the inlet pipe and sent to the next treatment process through the outlet pipe.

[0013] Preferably, a second water pipe is fixedly connected to the top side wall of the supporting shell, and the bottom side wall of the sewage treatment shell is inclined toward the second water pipe.

[0014] In this technical solution, the water drained from the basket is collected and enters the support shell through the second water pipe.

[0015] Preferably, the filter structure includes a filter screen, a fixing frame, and a water pipe. The filter screen is fixedly connected to the top side wall of the fixing frame, and both ends of the filter screen and the fixing frame are fixedly connected to the inner side wall of the sewage treatment shell. One end of the water pipe is fixedly connected to the side wall where the sewage treatment shell and the fixing frame are connected, and the other end of the water pipe is fixedly connected to the side wall of the supporting shell.

[0016] In this technical solution, the filter screen filters and intercepts impurities in the falling sewage. The filtered sewage falls onto the fixed frame below and then flows into the support housing through the water pipe.

[0017] Preferably, the bottom sidewall of the fixing frame is configured as a flat plate structure, and the sidewalls of the filter screen and the sidewalls on both sides of the fixing frame are configured as arcs.

[0018] In this technical solution, some impurities will always adhere to the side wall of the filter screen under the action of water. However, when the cleaning scraper pushes the impurities to the plate at the bottom of the fixed frame, the lack of an arc surface along the pushing direction for adsorption allows these impurities to fall off relatively well.

[0019] Preferably, the cleaning structure includes a rotating plate, a cleaning scraper, a rotating connecting ring, a rotating toothed groove, a rotating gear, and a rotating motor. The rotating connecting ring is rotatably connected to the outside of the filter screen and the fixing frame. Two rotating plates are fixedly connected to the side walls on opposite sides of the rotating connecting ring. The other side wall of the rotating connecting ring is rotatably connected to the inner side wall of the sewage treatment shell. A cleaning scraper is fixedly connected at equal distances between the two rotating plates. A rotating toothed groove is provided on the side wall of the rotating connecting ring. The rotating motor is fixedly connected to the side wall of the sewage treatment shell, and the rotating end of the rotating motor is fixedly connected to the rotating gear.

[0020] In this technical solution, the rotating motor rotates, which drives the rotating gear to rotate. The rotating gear rotates inside the rotating gear, which drives the rotating connecting ring to rotate. The rotating connecting ring drives the cleaning scraper to rotate around the side wall of the filter screen.

[0021] Preferably, the rotating gear and the rotating tooth groove mesh with each other.

[0022] Preferably, the cleaning scraper is attached to the side wall of the filter screen.

[0023] In this technical solution, the cleaning scraper pushes the impurities filtered out of the filter screen to move during the rotation process.

[0024] Preferably, the striking structure includes a fixed block, a rotating ring, a connecting rod, a striking ball, a torsion spring, and a fixed rod. The fixed block is fixedly connected to the bottom side wall of the fixed frame. A fixed rod is fixedly connected between the fixed blocks. A rotating ring is rotatably connected to the fixed rod. Torsion springs are fixedly connected between the two ends of the rotating ring and the fixed block. Two connecting rods are fixedly connected to the side wall of the rotating ring. The other ends of the two connecting rods are fixedly connected to the striking ball.

[0025] In this technical solution, when the cleaning scraper passes the striking ball, it pushes the striking ball to move. The striking ball drives the connecting rod to move, and the connecting rod rotates around the fixed rod. The torsion spring twists. When the cleaning scraper separates from the striking ball, the striking ball is no longer pushed and bounces back sharply under the action of the torsion spring. During the bounce back, it hits the side wall of the next cleaning scraper, striking the cleaning scraper and causing it to vibrate.

[0026] Preferably, the collection structure includes a baffle, a sealing gasket, a handle bracket, and a collection basket. The baffle is fixedly connected to the side wall of the collection basket, the sealing gasket is fixedly connected to the side walls of the four sides of the baffle, the handle bracket is fixedly connected to the front side wall of the baffle, and the collection basket and the baffle are slidably connected to the bottom inner side wall of the sewage treatment shell.

[0027] In this technical solution, the sealing gasket ensures a sealed connection between the baffle and the sewage treatment housing.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0029] The positive and progressive effects of this utility model are as follows:

[0030] 1. The rotating motor drives the rotating gear to rotate, which in turn drives the rotating connecting ring to rotate. The rotating connecting ring drives the cleaning scraper to rotate around the side wall of the filter screen. During the rotation, the cleaning scraper pushes the impurities filtered out of the filter screen to move, so that the impurities leave the filter screen. This facilitates the timely cleaning of the filtered impurities and prevents them from clogging the filter screen holes and affecting the filtration effect.

[0031] 2. When the cleaning scraper pushes impurities to the flat plate at the bottom of the fixed frame, the impurities, which always adhere to the side wall of the filter screen and move under the action of water, can fall down well and enter the collection basket due to the lack of an arc surface along the pushing direction for adsorption. When the cleaning scraper passes the tapping ball, it pushes the tapping ball to move, and the torsion spring twists. When the cleaning scraper separates from the tapping ball, the tapping ball is no longer pushed and bounces back sharply under the action of the torsion spring. During the bounce, it will hit the side wall of the next cleaning scraper, causing the cleaning scraper to vibrate. This effectively knocks off the impurities adhering to the cleaning scraper and makes them fall into the collection basket for collection, which facilitates the collection and treatment of filtered impurities.

[0037] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0038] like Figure 1-3 As shown, a wastewater pretreatment device includes a wastewater treatment shell 10, and further includes:

[0039] Filter structure 6 is installed inside the wastewater treatment housing 10;

[0040] Cleaning structure 7 is installed on filter structure 6;

[0041] The tapping structure 9 is located at the bottom of the filter structure 6 and taps and cleans the cleaning structure 7.

[0042] Collection structure 3 is located below filter structure 6.

[0043] Four support columns 4 are fixedly connected to the bottom side wall of the sewage treatment shell 10. The bottom of the four support columns 4 is fixedly connected to the support shell 1. A drain pipe 2 is fixedly connected to one side wall of the support shell 1. An inlet pipe 5 is fixedly connected to the top side wall of the sewage treatment shell 10.

[0044] Wastewater is introduced into the wastewater treatment shell 10 through the inlet pipe 5 and sent to the next treatment process through the outlet pipe 2.

[0045] A water pipe 2 8 is fixedly connected to the top side wall of the supporting shell 1, and the bottom side wall of the sewage treatment shell 10 is inclined toward the water pipe 2 8.

[0046] The water drained from the basket 304 is collected and enters the support shell 1 through the water pipe 2 8.

[0047] The filter structure 6 includes a filter screen 601, a fixing frame 602, and a water pipe 603. The filter screen 601 is fixedly connected to the top side wall of the fixing frame 602. Both ends of the filter screen 601 and the fixing frame 602 are fixedly connected to the inner side wall of the sewage treatment shell 10. One end of the water pipe 603 is fixedly connected to the side wall where the sewage treatment shell 10 and the fixing frame 602 are connected, and the other end of the water pipe 603 is fixedly connected to the side wall of the supporting shell 1.

[0048] The filter screen 601 filters and intercepts impurities in the falling sewage. The filtered sewage falls onto the fixed frame 602 below and then flows into the support housing 1 through the water pipe 603.

[0049] The bottom sidewall of the mounting bracket 602 is designed as a flat plate, and the sidewalls of the filter screen 601 and the sidewalls on both sides of the mounting bracket 602 are designed as arcs.

[0050] Some impurities will always adhere to the side wall of the filter screen 601 under the action of water. However, when the cleaning scraper 702 pushes the impurities to the flat plate at the bottom of the fixing frame 602, the lack of an arc surface along the pushing direction for adsorption allows these impurities to fall off relatively well.

[0051] The cleaning structure 7 includes a rotating plate 701, a cleaning scraper 702, a rotating connecting ring 703, a rotating toothed groove 704, a rotating gear 705, and a rotating motor 706. The rotating connecting ring 703 is rotatably connected to the outside of the filter screen 601 and the fixing frame 602. Two rotating plates 701 are fixedly connected to the side walls on opposite sides of the rotating connecting ring 703. The other side wall of the rotating connecting ring 703 is rotatably connected to the inner side wall of the sewage treatment housing 10. The cleaning scraper 702 is fixedly connected at equal distances between the two rotating plates 701. The rotating toothed groove 704 is opened on the side wall of the rotating connecting ring 703. The rotating motor 706 is fixedly connected to the side wall of the sewage treatment housing 10. The rotating end of the rotating motor 706 is fixedly connected to the rotating gear 705.

[0052] The rotating motor 706 rotates, which drives the rotating gear 705 to rotate. The rotating gear 705 rotates within the rotating gear 705, which drives the rotating connecting ring 703 to rotate. The rotating connecting ring 703 drives the cleaning scraper 702 to rotate around the side wall of the filter screen 601.

[0053] Rotating gear 705 and rotating tooth groove 704 mesh with each other.

[0054] The cleaning scraper 702 is attached to the side wall of the filter screen 601.

[0055] The cleaning scraper 702 moves the impurities filtered out on the filter screen 601 as it rotates.

[0056] The striking structure 9 includes a fixed block 901, a rotating ring 902, a connecting rod 903, a striking ball 904, a torsion spring 905, and a fixed rod 906. The fixed block 901 is fixedly connected to the bottom side wall of the fixed frame 602. The fixed rod 906 is fixedly connected between the fixed blocks 901. The rotating ring 902 is rotatably connected to the fixed rod 906. The two ends of the rotating ring 902 are fixedly connected to the fixed block 901 with torsion springs 905. Two connecting rods 903 are fixedly connected to the side wall of the rotating ring 902. The other ends of the two connecting rods 903 are fixedly connected to the striking ball 904.

[0057] When the cleaning scraper 702 passes the striking ball 904, it pushes the striking ball 904 to move. The striking ball 904 drives the connecting rod 903 to move, and the connecting rod 903 drives the rotating ring 902 to rotate around the fixed rod 906. The torsion spring 905 is twisted. When the cleaning scraper 702 separates from the striking ball 904, the striking ball is no longer pushed and bounces back sharply under the action of the torsion spring 905. During the bounce back, it will hit the side wall of the next cleaning scraper 702, knocking on the cleaning scraper 702 and causing the cleaning scraper 702 to vibrate.

[0058] The collection structure 3 includes a baffle 301, a sealing gasket 302, a handle bracket 303, and a collection basket 304. The baffle 301 is fixedly connected to the side wall of the collection basket 304. The sealing gasket 302 is fixedly connected to the side walls of the four sides of the baffle 301. The handle bracket 303 is fixedly connected to the front side wall of the baffle 301. The collection basket 304 and the baffle 301 are slidably connected to the bottom inner side wall of the sewage treatment shell 10.

[0059] The sealing gasket 302 ensures a sealed connection between the baffle 301 and the wastewater treatment housing 10.

[0060] In use, the electrical components mentioned in this application are all connected to an external power supply and control switch. Sewage is introduced into the sewage treatment housing 10 through the inlet pipe 5. The filter screen 601 filters and intercepts impurities in the sewage. The filtered sewage falls onto the fixed frame 602 below, and then enters the support housing 1 through the water pipe 603. Finally, it is sent to the next treatment process through the drain pipe 2. The filtered impurities remain on the filter screen 601.

[0061] The rotating motor 706 rotates, driving the rotating gear 705 to rotate. The rotating gear 705 rotates within the rotating gear 705, driving the rotating connecting ring 703 to rotate. The rotating connecting ring 703 drives the cleaning scraper 702 to rotate around the side wall of the filter screen 601. During the rotation, the cleaning scraper 702 pushes the impurities filtered out on the filter screen 601 to move, causing the impurities to leave the filter screen 601. Some impurities will always stick to the side wall of the filter screen 601 under the action of water. However, when the cleaning scraper 702 pushes the impurities to the flat plate at the bottom of the fixed frame 602, due to the lack of an arc surface along the pushing direction for adsorption, these impurities can fall down better and enter the collection basket 304 for collection. This effectively and timely cleans the filtered impurities, preventing them from clogging the filter screen 601 holes and affecting the filtration effect.

[0062] When the cleaning scraper 702 passes the striking ball 904, it pushes the striking ball 904 to move. The striking ball 904 drives the connecting rod 903 to move, and the connecting rod 903 drives the rotating ring 902 to rotate around the fixed rod 906. The torsion spring 905 is twisted. When the cleaning scraper 702 separates from the striking ball 904, the striking ball is no longer pushed and bounces back sharply under the action of the torsion spring 905. During the bounce back, it hits the side wall of the next cleaning scraper 702, knocking the cleaning scraper 702 and causing it to vibrate. This effectively knocks off the impurities adhering to the cleaning scraper 702, which fall into the collection basket 304 for collection, facilitating the collection and processing of the filtered impurities.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
