Description

Technical Field

[0001] This utility model relates to the field of chemical wastewater filtration technology, specifically to a multi-stage filtration device for chemical wastewater. Background Technology

[0002] Chemical wastewater filtration is a physical separation technology in chemical wastewater treatment. Its core purpose is to remove suspended particles, colloidal substances and some organic pollutants from wastewater through mechanical interception, so as to reduce turbidity, improve water quality and provide a basis for subsequent treatment or reuse.

[0003] With the development of technology, the composition of chemical wastewater is becoming increasingly complex, often containing various pollutants such as suspended particles, colloids, dissolved organic matter, and heavy metals. Different filtration methods are required for chemical wastewater with different pollution levels. However, existing filtration technologies are often single treatment methods using physical or chemical agents, which are difficult to meet the filtration needs of chemical wastewater with different pollution levels. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-stage filtration device for chemical wastewater in order to solve the above-mentioned problems. The device has two states, namely, the first filtration mechanism and the second filtration mechanism, which can be assembled and separated, in order to deal with chemical wastewater with different pollution levels.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A multi-stage filtration device for chemical wastewater includes: a first filtration mechanism and a second filtration mechanism. The first filtration mechanism has a first filter outlet at the lower front side, and the second filtration mechanism has a second filter outlet at the lower front side. The second filtration mechanism has a feed inlet at the top side. A connecting pipe is fixedly installed between the first filtration mechanism and the second filtration mechanism. Limiting plates are fixedly installed on both sides of the inner wall of the first filtration mechanism at the upper side.

[0007] The first filtering mechanism includes a first filter frame. Guide plates are fixedly installed on both sides of the upper part of the inner wall of the first filter frame. A filter screen is fixedly installed between the two guide plates. A drive shaft is rotatably installed through one side of the first filter frame.

[0009] Furthermore, a triangular guide plate is fixedly installed in the middle of the front side of the inner wall of the first filter frame. The triangular guide plate is triangular in shape and is located below the filter screen. The triangular guide plate is inclined from front to back.

[0010] Furthermore, the second filtering mechanism includes a second filter frame, and three limiting shafts are fixedly provided on one side of the inner wall of the second filter frame.

[0011] Furthermore, each of the three limiting shafts is fixedly provided with an elliptical push block on its front side, and a transmission belt is slidably provided on the outer side of the three limiting shafts, with one side of the inner wall of the transmission belt meshing with the transmission teeth.

[0012] Furthermore, a filter diversion mechanism is fixedly installed on the top side of the first filter mechanism. The filter diversion mechanism includes a drive motor and three limiting rods. A threaded rod is fixedly installed on the bottom output end of the drive motor. A first blocking plate is threadedly sleeved on the lower part of the threaded rod.

[0013] Furthermore, the three limiting rods are longitudinally slidably provided with second blocking plates, and an L-shaped connecting rod is provided between the first blocking plate and the second blocking plate.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 and Figure 2As shown, this utility model provides a multi-stage filtration device for chemical wastewater, including: a first filtration mechanism 1 and a second filtration mechanism 2. The first filtration mechanism 1 has a first filter outlet 3 at the lower front side, the second filtration mechanism 2 has a second filter outlet 7 at the lower front side, the second filtration mechanism 2 has a feeding port 6 at the top side, a connecting pipe 8 is fixedly arranged between the first filtration mechanism 1 and the second filtration mechanism 2, and limit plates 5 are fixedly arranged on both sides of the inner wall of the first filtration mechanism 1 at the upper side.

[0031] Using the above technical solution, the first filtration mechanism 1 performs preliminary filtration of chemical wastewater and provides power to drive the internal structure of the second filtration mechanism 2. The wastewater filtered by the first filtration mechanism 1 can be discharged through the first filtration outlet 3, allowing the less polluted chemical wastewater to be discharged quickly after filtration. Through the cooperation between the second filtration mechanism 2 and the feeding port 6, chemical agents are used to filter the chemical wastewater. Finally, the filtered wastewater is discharged through the second filtration outlet 7. The connecting pipe 8 between the first filtration mechanism 1 and the second filtration mechanism 2 allows the wastewater to undergo continuous multi-stage filtration.

[0032] See Figures 6-8 As shown, the first filter mechanism 1 includes a first filter frame 101. Guide plates 104 are fixedly installed on both the upper sides of the inner wall of the first filter frame 101, and a filter screen 105 is fixedly installed between two guide plates 104. A drive shaft 102 is rotatably installed through one side of the first filter frame 101, and several force-bearing plates 103 are fixedly installed on one side of the drive shaft 102. These force-bearing plates 103 are located below the filter screen 105. A drive gear 107 is fixedly installed on the side of the drive shaft 102 away from the force-bearing plates 103. A triangular guide plate 106 is fixedly installed in the middle of the front side of the inner wall of the first filter frame 101. The triangular diversion plate 106 is triangular in shape and is located below the filter screen 105. The triangular diversion plate 106 is inclined from front to back. A filter diversion mechanism 4 is fixedly installed on the top side of the first filter mechanism 1. The filter diversion mechanism 4 includes a drive motor 401 and three limiting rods 405. A threaded rod 402 is fixedly installed on the bottom output end of the drive motor 401. A first blocking plate 403 is threadedly sleeved on the lower part of the threaded rod 402. A second blocking plate 406 is slidably installed on the three limiting rods 405. An L-shaped connecting rod 404 is provided between the first blocking plate 403 and the second blocking plate 406.

[0033] In use, the chemical wastewater entering the first filter frame 101 is concentrated and sent to the top of the filter screen 105 through the two guide plates 104 on the upper inner wall of the first filter frame 101. The filter screen 105 filters the chemical wastewater. After filtration, the chemical wastewater permeates downward and falls onto the surface of the triangular guide plate 106. The triangular guide plate 106 then concentrates the filtered wastewater to the force plate 103, causing the force plate 103 to rotate. This rotation drives the transmission gear 107 through the transmission shaft 102, cooperating with the second filter mechanism 2. When the chemical wastewater is lightly polluted, the drive motor 401 in the filter diversion mechanism 4 sets the first baffle plate 403 to the lowest position, and the L-shaped connecting rod 404 keeps the first baffle plate 403 in a lower position. At this time, the second baffle plate 406 is located below the first filter outlet 3 and does not block the first filter outlet 3. The filtered wastewater can be directly discharged from the first filter mechanism 1 from here. When the wastewater needs to be filtered a second time, the drive motor 401 drives the first baffle plate 403 to rise continuously through the threaded rod 402. The L-shaped connecting rod 404 between the first baffle plate 403 and the second baffle plate 406 drives the second baffle plate 406 to slide upward in the three limiting rods 405 until the first baffle plate 403 opens the connecting pipe 8 between the first filter mechanism 1 and the second filter mechanism 2, so that the second baffle plate 406 closes the first filter outlet 3. At this time, the wastewater filtered by the filter screen 105 can enter the second filter mechanism 2 through the connecting pipe 8 for secondary filtration.

[0034] See Figures 2-5 As shown, the second filter mechanism 2 includes a second filter frame 201. Three limiting shafts 202 are fixedly installed on one side of the inner wall of the second filter frame 201. An elliptical push block 203 is fixedly installed on the front side of each of the three limiting shafts 202. A transmission belt 204 is slidably installed on the outer side of the three limiting shafts 202. One side of the inner wall of the transmission belt 204 meshes with a transmission gear 107. Several stirring mechanisms 9 are rotatably installed inside the second filter mechanism 2. Each stirring mechanism 9 includes a connecting rod 901. A receiving rod 902 is fixedly installed on one side of the connecting rod 901. A return spring 904 is fixedly installed on the side of the receiving rod 902 near the connecting rod 901. Four stirring blades 903 are fixedly installed on the body of the receiving rod 902. A force-bearing rod 905 is fixedly installed on the side of the receiving rod 902 near the connecting rod 901. The force-bearing rod 905 is L-shaped.

[0035] In the above embodiment, the transmission teeth 107 of the three limiting shafts 202 and the shaft body of the transmission shaft 102 support the transmission belt 204, and the transmission teeth 107 of the shaft body of the transmission shaft 102 mesh with the inner side of the transmission belt 204, so that the transmission belt 204 can be driven to rotate by the transmission teeth 107, which moves the stirring mechanism 9 on one side of the transmission belt 204. When the stirring mechanism 9 passes the elliptical push block 203 on one side of the three limiting shafts 202, the force-bearing rod 905 in the stirring mechanism 9 contacts the elliptical push block 203, and the force causes the receiving rod 902 and the connecting rod 905 to be connected. The rotating rod 901 rotates, causing the stirring blade 903 on the outside of the receiving rod 902 to stir the wastewater and chemical agents inside the second filter mechanism 2 evenly. After the force rod 905 and the elliptical push block 203 are released, the receiving rod 902 is reset by the return spring 904 set on the transmission belt 204 and the side of the receiving rod 902. The receiving rod 902, along with the connecting rod 901 and the stirring blade 903, stirs again, and the force rod 905 returns to the inner side, contacts the next elliptical push block 203, and then drives the stirring blade 903 to stir again.

[0036] Using the above structure, when wastewater filtration is required, the wastewater is first poured into the first filtration mechanism 1. Two guide plates 104 guide the wastewater to the middle filter screen 105, and the filter screen 105 performs preliminary filtration on the wastewater. The filtered wastewater falls from the filter screen 105 and flows to the triangular guide plate 106, and is transported by the triangular guide plate 106 to the rear side of the entire first filter frame 101, so that the filtered wastewater falls on the force plate 103. Through the impact force of the filtered wastewater, the force plate 103 rotates with the drive shaft 102, and the drive gear 107 on the side of the drive shaft 102 away from the force plate 103 rotates accordingly, forming a drive for the drive gear 107. At this time, the wastewater has been filtered for the first time through the filter screen 105. When the degree of pollution of the wastewater is low, the filtered wastewater can be directly discharged through the first filter outlet 3.

[0037] When wastewater needs to be filtered multiple times, the first baffle plate 403 is controlled by the threaded rod 402 at the output end of the drive motor 401 of the filter diversion mechanism 4. When secondary filtration is required, the drive motor 401 is started, and the thread engagement between the threaded rod 402 and the first baffle plate 403 causes the first baffle plate 403 to rise. During the rise of the first baffle plate 403, the first baffle plate 403 carries the second baffle plate 406 to slide longitudinally on the limiting rod 405 through the L-shaped connecting rod 404 until the first baffle plate 403 exposes the connecting pipe 8 between the first filter mechanism 1 and the second filter mechanism 2, and the second baffle plate 406 blocks the first filter outlet 3, thus completing the connection between the first filter mechanism 1 and the second filter mechanism 2 and performing secondary filtration of wastewater.

[0038] When wastewater enters the second filtration mechanism 2 through the connecting pipe 8, the first filtration mechanism 1 is still performing initial filtration on the wastewater. The filtered wastewater flows to the force plate 103, causing the drive shaft 102 and the drive gear 107 on the shaft to rotate. The drive gear 107 meshes with the inner side of the drive belt 204, causing the drive gear 107 to rotate the drive belt 204. This causes the drive belt 204 to move outside the drive gear 107 and the three limiting shafts 202, and also moves multiple stirring mechanisms 9 on one side of the drive belt 204. When the stirring mechanism 9 moves, the force rod 905 contacts the elliptical push block 203, causing the force rod 905 to move the entire... The rotation of the receiving rod 902 and the connecting rotating rod 901, along with the rotation of the stirring blades 903 on the outer surface of the receiving rod 902, stirs the wastewater inside the second filtration mechanism 2. The neutralizing chemical agent fed into the feeding port 6 on the upper side of the second filtration mechanism 2 is fully mixed with the wastewater, maximizing the effectiveness of the agent. When the force rod 905 is no longer in contact with the elliptical push block 203, the return spring 904 between the receiving rod 902 and the transmission belt 204 resets the receiving rod 902, causing the stirring blades 903 to rotate in the opposite direction and reset, performing secondary stirring to improve the mixing effect, enhance the chemical reaction effect, and improve the filtration effect of the wastewater.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
