Description

Technical Field

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

[0002] In the foundry industry, the production process generates a large amount of wastewater. Traditional wastewater treatment devices usually lack effective diversion measures when the wastewater enters the filtration stage, resulting in uneven distribution of wastewater during the filtration process. After long-term use, the filter components of the treatment equipment are easily clogged by impurities and need to be frequently replaced or cleaned. Therefore, a foundry wastewater treatment device is particularly needed.

[0003] A wastewater treatment device for aluminum alloy casting, authorized by announcement number CN218392421U, includes a wastewater treatment tank. A top cover is threadedly connected to the top of the wastewater treatment tank via four bolts. A sedimentation tank is fixedly installed on the outer wall of the wastewater treatment tank via two rectangular rods. In this invention, pulling upwards on the mounting block that is engaged inside the mounting hole causes the mounting block to move upwards within the connecting sleeve and disengage from the mounting hole. The filter screen is then cleaned. After cleaning, pressing the fixed mesh frame towards the four mounting blocks causes the mounting blocks to slide into the mounting hole under external force. Simultaneously, the mutual repulsion between magnet one and magnet two makes the mounting block more stable inside the mounting hole. After the fixed mesh frame is installed inside the wastewater treatment tank, wastewater treatment can continue. This facilitates timely disassembly and cleaning of the filter screen to avoid clogging of the filter screen and affecting wastewater treatment.

[0004] However, in one type of aluminum alloy casting wastewater treatment device, there is a problem that magnetic impurities in the wastewater are adsorbed onto the surface of the magnet during the filtration process, thereby interfering with the magnetic field distribution of the magnet and thus affecting the fixing effect of the fixed mesh frame and filter screen.

[0005] To address the aforementioned problems, a foundry wastewater treatment device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a foundry wastewater treatment device to solve the problems of existing foundry wastewater treatment devices mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a foundry wastewater treatment device, comprising a wastewater treatment tank, a fixing frame provided on the inner wall of the wastewater treatment tank, a composite filter embedded in the inner wall of the fixing frame, a disassembly mechanism provided between the fixing frame and the composite filter, and a diversion mechanism provided above the composite filter;

[0008] The disassembly mechanism includes a first sliding groove opened at the top four corners of the fixed frame, a second sliding groove opened at the top four corners of the composite filter, a first slider slidably connected to the inner wall of the first sliding groove, a limit block hinged to one end of the first slider, and a second slider provided at the bottom of the first slider.

[0009] The diversion mechanism includes hangers installed above both ends of the composite filter, with an overflow groove at the bottom of the hanger and an adjustment plate above the overflow groove.

[0010] Preferably, the disassembly mechanism further includes a stop block installed at one end of the first slide groove, a protrusion provided on the top of the first slider, and a rubber strip surrounding the outer side of the limiting block.

[0011] Preferably, the limiting block is disposed on the inner wall of the first sliding groove, and the stop block is disposed at the bottom of the limiting block.

[0012] Preferably, the second slider is disposed on the inner wall of the second slide groove and is slidably connected to the second slide groove.

[0013] Preferably, the diversion mechanism further includes a third slide groove at one end of the hanger, and the two ends of the adjusting plate are provided with third sliders. The inner wall of the third slider is provided with a threaded rod, and a friction block is provided between the top of the threaded rod and the top of the hanger.

[0014] Preferably, the overflow trough is attached to the inner wall of the wastewater treatment tank by means of a hanger, and the diversion point of the overflow trough is interlocked with the bottom of the regulating plate.

[0015] Preferably, the third slider is disposed on the inner wall of the third slide groove and is slidably connected to the third slide groove, and the threaded rod is threadedly connected to the third slider.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The foundry wastewater treatment device is equipped with a disassembly mechanism. By setting a first slide groove and a second slide groove on the fixed frame and the composite filter respectively, as well as components such as a first slider, a second slider and a limiting block, the operator only needs to rotate the limiting block and push the first slider to pull the composite filter out of the fixed frame. The composite filter can be disassembled and assembled without cumbersome operations, and the assembled composite filter has good stability.

[0018] The regulating plate in the diversion mechanism can be adjusted up and down through the cooperation of the threaded rod and the third slider. It can flexibly change the distance between the overflow tank diversion point and the bottom of the regulating plate according to the actual wastewater treatment needs, thereby controlling the flow rate of wastewater entering the composite filter. By dispersing the water flow, the overflow tank avoids the wastewater from concentrating in one place to enter the composite filter, so that the composite filter can play a more uniform filtration role and improve the filtration effect and efficiency.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example

[0027] like Figure 1-4 As shown, the device includes a wastewater treatment tank 1, a fixed frame 2 on the inner wall of the wastewater treatment tank 1, a composite filter 3 embedded in the inner wall of the fixed frame 2, and a disassembly mechanism 4 between the fixed frame 2 and the composite filter 3. The disassembly mechanism 4 includes a first sliding groove 401 opened at the top four corners of the fixed frame 2, a second sliding groove 402 opened at the top four corners of the composite filter 3, a first slider 403 slidably connected to the inner wall of the first sliding groove 401, a limit block 404 hinged to one end of the first slider 403, a second slider 405 at the bottom of the first slider 403, a stop block 406 installed at one end of the first sliding groove 401, a protrusion 407 at the top of the first slider 403, and a rubber strip 408 surrounding the outer side of the limit block 404.

[0028] It should be noted that in this embodiment, when the composite filter 3 needs to be disassembled for cleaning or replacement, the first slide groove 401 is opened at the top four corners of the fixed frame 2, and the second slide groove 402 is opened at the top four corners of the composite filter 3. The first slide groove 401 is slidably connected to the first slider 403, one end of the first slider 403 is hinged to the limiting block 404, and the bottom is provided with the second slider 405. Since the limiting block 404 is surrounded by a rubber strip 408, it is in close contact with the inner wall of the first slide groove 401 and plays a limiting role. At this time, the limiting block 404 is rotated away from the inner wall of the first slide groove 401. The first slider 403 is moved to separate from the inner wall of the first slide groove 401. At the same time, the top of the first slider 403 is provided with a protrusion 407, which makes it easy for the operator to push the first slider 403 to slide in the first slide groove 401. At this time, the second slider 405 slides synchronously in the second slide groove 402. When the second slider 405 slides to the point where it loses the limit of the second slide groove 402, it is convenient to pull the composite filter 3 out of the fixed frame 2. The stop block 406 installed at one end of the first slide groove 401 is used to limit the position of the limit block 404, so that the limit block 404 remains horizontal when installed in the first slide groove 401.

[0029] like Figure 5 As shown, a diversion mechanism 5 is provided above the composite filter 3. The diversion mechanism 5 includes a hanger 501 installed above both ends of the composite filter 3. An overflow groove 502 is provided at the bottom of the hanger 501. An adjusting plate 503 is provided above the overflow groove 502. The diversion mechanism 5 also includes a third sliding groove 504 opened at one end of the hanger 501. A third slider 505 is provided at both ends of the adjusting plate 503. A threaded rod 506 is provided on the inner wall of the third slider 505. A friction block 507 is provided between the top of the threaded rod 506 and the top of the hanger 501.

[0030] It should be noted that in this embodiment, when wastewater flows into the overflow tank 502 through the inlet pipe, the distance between the diversion point of the overflow tank 502 and the bottom of the adjustment plate 503 can be changed by adjusting the position of the adjustment plate 503, thereby adjusting the flow distribution of wastewater entering the composite filter 3. Specifically, the adjustment method is as follows: a third slide groove 504 is opened at one end of the hanger 501, and the third sliders 505 at both ends of the adjustment plate 503 are located on the inner wall of the third slide groove 504 and can be slidably connected. The threaded rod 506 is threadedly connected to the third slider 505. By rotating the threaded rod 506, the third slider 505 can move up and down in the third slide groove 504, thereby driving the adjustment plate 503 to rise or fall, thereby realizing the flow adjustment of wastewater distribution. At the same time, a friction block 507 is provided between the top of the threaded rod 506 and the top of the hanger 501. When the adjustment is in a suitable position, the friction block 507 is limited by adjusting the bolt on one side of the friction block to prevent the threaded rod 506 from rotating on its own and keep the position of the adjustment plate 503 stable.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual appendix Figure 1-5 When wastewater flows into the overflow tank 502 through the inlet pipe, the distance between the diversion point of the overflow tank 502 and the bottom of the adjustment plate 503 can be changed by adjusting the position of the adjustment plate 503, thereby adjusting the flow distribution of wastewater entering the composite filter 3. The specific adjustment method is as follows: a third slide groove 504 is opened at one end of the hanger 501, and the third sliders 505 at both ends of the adjustment plate 503 are set on the inner wall of the third slide groove 504 and can be slidably connected. The threaded rod 506 is threadedly connected to the third slider 505. By rotating the threaded rod 506, the third slider 505 can move up and down in the third slide groove 504, thereby driving the adjustment plate 503 to rise or fall, so as to realize the flow regulation of wastewater distribution. At the same time, a friction block 507 is provided between the top of the threaded rod 506 and the top of the hanger 501. When the adjustment is in a suitable position, the friction block 507 is limited by adjusting the bolt on one side of the friction block to prevent the threaded rod 506 from rotating on its own and keep the position of the adjustment plate 503 stable.

[0033] After being diverted and regulated, the wastewater flows into the composite filter 3 for filtration treatment.

[0034] When the composite filter 3 needs to be disassembled for cleaning or replacement, the first slide groove 401 is opened at the top four corners of the fixed frame 2, and the second slide groove 402 is opened at the top four corners of the composite filter 3. The first slide groove 401 is slidably connected to the first slider 403. One end of the first slider 403 is hinged to the limiting block 404, and the bottom is provided with the second slider 405. Since the limiting block 404 is surrounded by a rubber strip 408, it is in close contact with the inner wall of the first slide groove 401 to play a limiting role. At this time, the limiting block 404 is rotated away from the inner wall of the first slide groove 401, so that it is in close contact with the first slide groove 405. The inner wall of the slide groove 401 is separated. At the same time, the top of the first slider 403 is provided with a protrusion 407, which makes it easy for the operator to push the first slider 403 to slide in the first slide groove 401. At this time, the second slider 405 slides synchronously in the second slide groove 402. When the second slider 405 slides to the point where it loses the limit of the second slide groove 402, it is convenient to pull the composite filter 3 out of the fixed frame 2. The stop block 406 installed at one end of the first slide groove 401 is used to limit the position of the limiting block 404, so that the limiting block 404 remains horizontal when installed in the first slide groove 401.
