Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more particularly to a wastewater treatment device for ceramic tile production. Background Technology

[0002] After the production of ceramic floor tiles is completed, the wastewater from the ceramic floor tile production process is transported to a wastewater treatment plant for treatment. During the treatment process, the ceramic floor tile wastewater is transferred to a sedimentation area where particulate matter in the wastewater begins to settle, such as... Figure 6 As shown, large particles settle rapidly in the sedimentation zone, resulting in a short sedimentation curve path, as... Figure 7 As shown, small particles settle slowly and have long sedimentation curves. Small particles are easily carried by overflowing water and transferred to subsequent treatment steps. Over time, a large number of small particles are transferred to subsequent treatment steps, affecting the subsequent treatment of wastewater.

[0003] Meanwhile, regardless of whether the particles are large or small, when they settle in the sedimentation area, they will cover the entire sedimentation area. Currently, a cleaning mechanism continuously cleans the particles in the sedimentation area. The cleaning mechanism pushes the particles to the particle collection point for collection and cleaning. When the cleaning mechanism pushes the particles, it affects the particles and water flow. Some particles are affected and become dispersed. The water flow is affected and flows faster to the right. The dispersed particles are transferred to the right with the faster water flow, making it easier for the dispersed particles to be transferred to the subsequent treatment steps. Summary of the Invention

[0004] To overcome the disadvantages of slow sedimentation rate of small particles, long sedimentation curve path, and the fact that small particles are easily transferred to subsequent treatment steps by overflowing water, this invention provides a wastewater treatment device for ceramic tile production.

[0005] The technical solution of this invention is: a wastewater treatment device for ceramic tile production, comprising a flocculation tank, a sedimentation tank, and an effluent channel; the right side of the flocculation tank is connected to the sedimentation tank; several effluent channels are installed on the right side of the sedimentation tank; it also includes sludge suction pipes, a diversion tank, and a storage tank; the sedimentation tank is provided with an extension section for extending the sedimentation path of small particles; a diversion tank for collecting large and small particles is installed on the sedimentation tank; a storage tank for collecting large particles is installed on the sedimentation tank, the storage tank is connected to the diversion tank, and there is a buffer gap between the storage tank and the left wall of the sedimentation tank; several sludge suction pipes are installed in both the diversion tank and the storage tank.

[0006] More preferably, the diversion pool is designed with a slope that is higher on the left and lower on the right.

[0007] More preferably, it also includes a partition plate; a partition plate is installed on the right side of the sedimentation tank, and the partition plate is located above the diversion tank.

[0008] More preferably, the partition is designed to be tilted with the left side higher than the right side.

[0009] More preferably, it also includes a guide plate; several guide plates are fixed to the right side of the sedimentation tank.

[0010] More preferably, the sedimentation tank has chamfered edges.

[0011] More preferably, it also includes an anti-clogging component; all sludge suction pipes are equipped with an anti-clogging component; the anti-clogging component includes a connecting pipe, a ball I, a connecting rod, and a ball II; the bottom of the sludge suction pipe is connected to the connecting pipe; the connecting pipe contains a ball I; the bottom of the ball I is fixedly connected to the connecting rod, and the connecting rod has staggered round rods; the bottom of the connecting pipe is fixedly connected to the ball II.

[0012] More preferably, the sphere II has a through groove.

[0013] More preferably, it also includes an arc-shaped plate and an elastic band; several arc-shaped plates are fixed to the bottom of all the connecting pipes, and the arc-shaped plates connected to the bottom of each connecting pipe together form a hollow cylinder; the arc-shaped plates connected to the bottom of each connecting pipe are connected to an elastic band.

[0014] More preferably, it also includes wedge blocks; all the curved plates are fixed to the bottom with wedge blocks.

[0015] The beneficial effects are: by adding an extension to the right side of the sedimentation tank, the water flow path is increased, allowing particles moving to the right to pass through the traction area of ​​the effluent channel and continue to move to the right, thus preventing particles from remaining in the traction area of ​​the effluent channel and being pulled into it by the surrounding water flow, which would affect the treatment of ceramic tile wastewater.

[0016] When the present invention uses a sludge suction pipe to suction the particulate matter settled in the sedimentation tank, the sludge suction pipe also suctions the water above it. When the water at the extension moves towards the sludge suction pipe, the water moving towards the sludge suction pipe will carry the settled particulate matter at the extension downward, which is conducive to the cleaning of the particulate matter.

[0017] This invention adds a storage tank to the right side of the sedimentation tank, allowing most of the faster-setting particles to settle in the storage tank. Meanwhile, particles located at the connection between the flocculation tank and the sedimentation tank can be transferred to the storage tank by the water flow from the flocculation tank. By adding a chamfer to the sedimentation tank, the particles can be guided to more easily transfer to the storage tank.

[0018] This invention adds a diversion tank to the right side of the sedimentation tank, which is connected to the storage tank. This allows the remaining particles that settle faster and those that settle slower to settle in the diversion tank. The particles are then automatically collected without the need for a cleaning mechanism to push and collect them. This avoids the impact of the cleaning mechanism on the particles and water flow, reduces the steps required for particle collection and cleaning, lowers the workload of staff, and reduces power and maintenance costs.

[0019] This invention adds a partition plate inside the sedimentation tank to separate the water in the sedimentation tank and the diversion tank, thereby reducing the pulling effect of the water flow around the outlet channel on the particles in the diversion tank. Furthermore, there is a space between the partition plate and the right side of the sedimentation tank, and the partition plate is tilted with the left side higher than the right side, so that the particles settled on the partition plate can be transferred to the diversion tank.

[0020] This invention adds three guide plates that gradually rotate upwards from left to right inside the sedimentation tank. When the water flowing to the right comes into contact with the guide plates, part of the water flowing to the right is guided by the guide plates to flow into the diversion tank. The water flowing into the diversion tank pushes the particles, making the particles that have settled in the diversion tank better transfer towards the sludge suction pipe, allowing the particles to better gather around the sludge suction pipe, making it easier for the sludge suction pipe to suck up and clean the particles.

[0021] This invention uses sphere I to drive the connecting rod and sphere II to move upward. When sphere II moves upward, the connecting rod moves upward as well. The round rod on the connecting rod pushes the bottom of the connecting tube, causing the particles at the bottom of the connecting tube to loosen and making it easier to extract the particles.

[0022] This invention adds an arc-shaped plate and an elastic band to the bottom of the connecting pipe. When the sphere II moves upward, the upward movement of the sphere II pushes the arc-shaped plate, and the sphere II opens up the bottom of the hollow cylinder composed of four arc-shaped plates. The bottoms of the four arc-shaped plates separate, and the elastic band begins to stretch and deform under force, so that the particles around the mud suction pipe can be transferred from between the four arc-shaped plates into the connecting pipe, thereby increasing the number of particles sucked into the connecting pipe.

[0023] This invention adds wedge blocks to the arc-shaped plates. When the sphere II moves upward, the wedge blocks are pushed, which increases the separation of the bottom of the arc-shaped plates and increases the gap between the four arc-shaped plates. More particles can be transferred from between the four arc-shaped plates into the connecting pipe, thereby further improving the efficiency of particle extraction. Attached Figure Description

Detailed Implementation

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] A wastewater treatment device for ceramic tile production, such as Figures 1-3 and Figures 6-7 As shown, it includes a flocculation tank 1, a sedimentation tank 2, and an outlet channel 3; the right side of the flocculation tank 1 is connected to the sedimentation tank 2; three outlet channels 3 are installed on the right side of the sedimentation tank 2.

[0035] It also includes a sludge suction pipe 4, a diversion tank 5, and a storage tank 101; the sedimentation tank 2 is provided with an extension 22; the diversion tank 5 is installed on the sedimentation tank 2; the storage tank 101 is installed on the sedimentation tank 2, and the storage tank 101 is connected to the diversion tank 5. There is a buffer gap between the storage tank 101 and the left wall of the sedimentation tank 2 to prevent the wastewater entering the sedimentation tank 2 from impacting the storage tank 101 and affecting the collection of particulate matter in the storage tank 101; four sludge suction pipes 4 are installed in both the diversion tank 5 and the storage tank 101.

[0036] The diversion tank 5 is designed with a slope that is higher on the left and lower on the right, which facilitates the transfer of particulate matter to the area below the sludge suction pipe 4.

[0037] It also includes a partition plate 6; a partition plate 6 is installed on the right side of the sedimentation tank 2, and the partition plate 6 is located above the diversion tank 5.

[0038] The partition plate 6 is designed with a left-high and right-low tilt, which allows the particles on the partition plate 6 to be better transferred into the diversion tank 5.

[0039] It also includes a guide plate 7; three guide plates 7 are fixed to the right side of the sedimentation tank 2, which gradually flip upwards from left to right.

[0040] The sedimentation tank 2 has a chamfer 21 to facilitate the transfer of particulate matter to the storage tank 101.

[0041] After the production of ceramic floor tiles is completed, the wastewater from ceramic floor tile production is transported to a sewage treatment plant for treatment. During the treatment process of ceramic floor tile wastewater, after the wastewater is transferred to the sedimentation area, the particulate matter in the wastewater begins to settle. Large particles settle quickly in the sedimentation area, and their sedimentation curve path is short, while small particles settle slowly, and their sedimentation curve path is long. Small particles are easily carried by the overflowing water and transferred to subsequent treatment steps. Over time, a large number of small particles are transferred to subsequent treatment steps, which affects the subsequent treatment of wastewater.

[0042] As water flows from flocculation tank 1 to sedimentation tank 2, and overflows from sedimentation tank 2 into effluent channel 3, particles in sedimentation tank 2 shift to the right. Since effluent channel 3 is typically located on the right side of sedimentation tank 2, the water flow into effluent channel 3 is directed towards the next step. This creates a certain traction force around effluent channel 3. After the particles reach the rightmost end of sedimentation tank 2, they are now within the traction area of ​​effluent channel 3, causing the water flow to carry them into effluent channel 3. The particles then move from effluent channel 3 to the next step, affecting the treatment of ceramic tile wastewater. This process is addressed by adding an extension channel on the right side of sedimentation tank 2. Section 22 increases the travel distance of the water flow, allowing particles moving to the right to pass through the traction area of ​​the outlet channel 3 and continue to move to the right. This prevents particles from remaining in the traction area of ​​the outlet channel 3 and being pulled into it by the surrounding water flow, which would affect the treatment of ceramic tile wastewater. Particles moving to the extension section 22 settle on it. When the sludge suction pipe 4 is used to suction the particles settled in the sedimentation tank 2, the sludge suction pipe 4 is also suctioning the water on it. When the water at the extension section 22 moves towards the sludge suction pipe 4, the water moving towards the sludge suction pipe 4 will carry the particles settled at the extension section 22 downwards, which is conducive to the cleaning of particles.

[0043] In the prior art, multiple particle collection points are set up in the sedimentation tank 2 to collect and clean the settled particles. A cleaning mechanism pushes the particles at the bottom of the sedimentation tank 2 to the particle collection points for collection and cleaning. During this process, the cleaning mechanism affects both the particles and the water flow. Some particles become dispersed, and the water flow accelerates to the right, causing the dispersed particles to follow the accelerated flow and move to the right. This makes it easier for the dispersed particles to be transferred to the outlet channel 3. By adding a storage tank 101 to the right side of the sedimentation tank 2, most of the faster-settling particles settle in the storage tank 101. Particles located at the connection between the flocculation tank 1 and the sedimentation tank 2 are transferred to the storage tank 101 by the water flow from the flocculation tank 1. A chamfer 21 is added to the sedimentation tank 2 to further facilitate the transfer of particles from the flocculation tank 1 to the storage tank 101. 1. Particulate matter is guided to more easily transfer from the sedimentation tank 2 to the storage tank 101. A diversion tank 5 is added to the right side of the sedimentation tank 2 and is connected to the storage tank 101. The remaining particles that settle faster and slower settle in the diversion tank 5. The particles are automatically collected in this way, eliminating the need for a cleaning mechanism to push and collect the particles. This avoids the impact of the cleaning mechanism on the particles and water flow, reduces the steps required for particle collection and cleaning, reduces the workload of the staff, and reduces power and maintenance costs. Power costs refer to the fixing parts for the push plate, the moving parts for driving the push plate, and the control parts, etc. Maintenance costs refer to the fact that ceramic tile wastewater contains corrosive substances that can easily cause corrosion damage to the push plate and other power mechanisms, requiring frequent maintenance. After the particles settle into the storage tank 101 and the diversion tank 5, the settled particles are sucked out through the sludge suction pipe 4.

[0044] By adding a partition plate 6 in the sedimentation tank 2, the water in the sedimentation tank 2 and the diversion tank 5 are separated by the partition plate 6, reducing the traction effect of the water flow around the outlet channel 3 on the particles in the diversion tank 5. In addition, there is a space between the partition plate 6 and the right side of the sedimentation tank 2. The partition plate 6 is tilted with the left side higher than the right side, so that the particles settled on the partition plate 6 can be transferred to the diversion tank 5.

[0045] After the particulate matter enters the diversion tank 5, by setting the diversion tank 5 to an inclined state with the left side higher than the right side, the particulate matter on the left side of the diversion tank 5 can be automatically transferred to the extraction range of the sludge suction pipe 4, which facilitates the subsequent cleaning of the particulate matter. By adding three guide plates 7 that gradually flip upward from left to right in the sedimentation tank 2, after the water flow moving to the right comes into contact with the guide plates 7, part of the water flow moving to the right is guided by the guide plates 7 to flow into the diversion tank 5. The water flow into the diversion tank 5 pushes the particulate matter, so that the particulate matter settled in the diversion tank 5 can be transferred to the direction of the sludge suction pipe 4 better, so that the particulate matter can be better gathered around the sludge suction pipe 4, making it easier for the sludge suction pipe 4 to suck up and clean the particulate matter.

[0046] Example 2

[0047] Based on Example 1, such as Figures 3-5 As shown, it also includes an anti-clogging component; all the mud suction pipes 4 are equipped with an anti-clogging component; the anti-clogging component includes a connecting pipe 110, a ball I 111, a connecting rod 112 and a ball II 113; the bottom of the mud suction pipe 4 is connected to the connecting pipe 110; the connecting pipe 110 contains a ball I 111; the bottom of the ball I 111 is fixedly connected to the connecting rod 112, and the connecting rod 112 has staggered round rods 1121; the bottom of the connecting pipe 110 is fixedly connected to the ball II 113.

[0048] The sphere II113 has a through groove 1131 to increase the amount of particulate matter drawn in.

[0049] It also includes an arc plate 114 and an elastic band 115; four annular array arc plates 114 are fixed to the bottom of all the connecting pipes 110, and the arc plates 114 connected to the bottom of each connecting pipe 110 together form a hollow cylinder; the arc plates 114 connected to the bottom of each connecting pipe 110 are connected to an elastic band 115.

[0050] It also includes wedge blocks 116; all the curved plates 114 are fixed to the bottom with wedge blocks 116.

[0051] When extracting particulate matter through the mud suction pipe 4, the suction volume of the mud suction pipe 4 is small due to the large accumulation of particulate matter, affecting the suction efficiency. By adding an anti-clogging component to the mud suction pipe 4, when no particulate matter is being extracted, the sphere I 111 blocks the upper end of the connecting pipe 110, preventing particulate matter from causing blockage in the connecting pipe 110. When extracting particulate matter, the sphere I 111 is pulled by suction, causing the connecting rod 112 and the sphere II 113 to move upward. When the sphere II 113 moves upward, the connecting rod 112 moves upward as well. The round rod 1121 pushes the bottom of the connecting tube 110, loosening the particles inside and facilitating their extraction. After the sphere II 113 contacts the bottom of the connecting tube 110, the connecting tube 110 restricts the sphere II 113, stopping the upward movement of the sphere I 111, the connecting rod 112, and the sphere II 113. The sphere I 111 remains at the upper center of the connecting tube 110. By creating a groove 1131 in the middle of the sphere II 113, particles can be transferred from the groove 1131 into the connecting tube 110, increasing the suction efficiency. The number of particles within the 110 pipe is reduced, and the particle extraction efficiency is improved. By adding an arc-shaped plate 114 and an elastic band 115 to the bottom of the connecting pipe 110, when the sphere II 113 moves upward, it pushes the arc-shaped plate 114. The sphere II 113 expands the bottom of the hollow cylinder formed by the four arc-shaped plates 114, causing the bottom of the four arc-shaped plates 114 to separate. The elastic band 115 then begins to stretch and deform under force, allowing particles around the mud suction pipe 4 to transfer from between the four arc-shaped plates 114 into the connecting pipe 110, further increasing the suction efficiency into the connecting pipe 110. The amount of internal particles is reduced by adding wedge blocks 116 to the arc plate 114. When the sphere II 113 moves upward, the wedge blocks 116 are pushed, increasing the separation of the bottom of the arc plate 114 and increasing the gap between the four arc plates 114. More particles can be transferred from between the four arc plates 114 into the connecting pipe 110, further improving the efficiency of particle extraction. After the mud suction pipe 4 stops suctioning, the elastic band 115 resets, thereby pulling the arc plate 114 to contract, which forces the sphere II 113 to drive the sphere I 111 to reset through the connecting rod 112.
