Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment. More specifically, this invention relates to a high-efficiency coagulation and sedimentation wastewater treatment device for recycled paper production. Background Technology

[0002] The production of recycled paper generates a large amount of wastewater. To avoid environmental pollution, the wastewater must be filtered and purified before discharge. Inclined plate sedimentation tanks are commonly used for this type of wastewater treatment. They contain corrugated inclined plates arranged in a staggered pattern, forming inclined channels between adjacent plates. As the wastewater flows upwards in these channels, suspended impurities settle due to gravity and slide down the inclined surfaces to the bottom of the tank. However, after long-term operation, flocs tend to adhere to the surface of the inclined plates, making it difficult for them to slide down smoothly and even causing blockages in the channels. Currently, conventional cleaning methods require emptying the sedimentation tank first, followed by manual cleaning of each channel individually, which is cumbersome and inefficient. Summary of the Invention

[0003] To address the problems of cumbersome operation and low efficiency caused by the need to empty the sedimentation tank and manually clean the flow channel in existing cleaning methods, this invention provides a high-efficiency coagulation sedimentation wastewater treatment device for recycled paper production.

[0004] The technical solution is as follows: A high-efficiency coagulation sedimentation wastewater treatment device for recycled paper production includes a box body and a partition plate 1 fixed to the box body; it also includes a partition plate 2, a bent plate 1, a bent plate 2, a corrugated plate 1, a corrugated plate 2, a drive assembly, a stirring assembly, and an inlet / outlet assembly; the partition plate 2 is fixed to the box body; the bent plate 1 is fixed to the box body; the bent plate 2 is fixed to the box body; several corrugated plates 1 are fixed to the box body; the drive assembly is connected to the box body; several corrugated plates 2 are connected to the drive assembly, and the corrugated plates 2 and corrugated plates 1 are alternately distributed; the drive assembly is used to drive the corrugated plates 2 to move horizontally; the stirring assembly is connected to the box body; the stirring assembly is used to stir the wastewater; the inlet / outlet assembly is connected to the box body to realize the input of wastewater, the output of treated wastewater, and the discharge of flocculated sludge.

[0005] Furthermore, the drive assembly includes an electric slide rail 1, an electric slider 1, a connecting plate 1, an electric slide rail 2, an electric slider 2, a connecting plate 2, and round rods; several electric slide rails 1 are fixedly connected to the housing; several electric sliders 1 are slidably connected to each electric slide rail 1; all electric sliders 1 are fixedly connected to a connecting plate 1; several electric slide rails 2 are fixedly connected to the connecting plate 1; several electric sliders 2 are slidably connected to each electric slide rail 2; all electric sliders 2 are fixedly connected to a connecting plate 2; several round rods are fixedly connected to the connecting plate 2, and the round rods are fixedly connected to the corresponding corrugated plates 2.

[0006] Furthermore, the stirring assembly includes a motor, a drive rod, and an impeller; several motors are fixedly connected to the housing; a drive rod is fixedly connected to the output end of each motor; and an impeller is fixedly connected to each drive rod.

[0007] Furthermore, the sludge inlet and outlet components include pipe one, pipe two, and pipe three; pipe one is connected to the box body; pipe two is connected to the box body; and pipe three is connected to the box body.

[0008] Furthermore, it also includes a baffle 1; several baffles 1 are fixedly connected between the bent plate 1 and the corresponding corrugated plate 1; several baffles 1 are fixedly connected between the bent plate 2 and the corresponding corrugated plate 1.

[0009] Furthermore, it also includes long strips; several long strips are fixed to the first corrugated plate; several long strips are also fixed to the second corrugated plate.

[0010] Furthermore, it also includes a filter screen; a filter screen is fixed between each pair of adjacent round rods.

[0011] Furthermore, it also includes a second baffle; a second baffle is fixed to each round rod in the front row and the back row, and the second baffle is inclined to the side away from the second bent plate; a gap is formed between the second baffle and the inner wall of the box.

[0012] Furthermore, it also includes a cleaning component, which includes a pipe four and a nozzle; the pipe four is fixedly connected to the connecting plate two; and several nozzles are connected to the pipe four.

[0013] Furthermore, the impeller surface is coated with an anti-corrosion coating.

[0014] The beneficial effects of the present invention are as follows: First, by setting the second corrugated plate to be movable, the first corrugated plate and the second corrugated plate used for settling can scrape each other during relative movement, thereby scraping off and cleaning the impurities adhering to their adjacent surfaces, avoiding the phenomenon of flocculation not sliding smoothly or blocking, and eliminating the need to use other tools to clean each settling channel one by one, thereby greatly improving the maintenance efficiency of the equipment. 2. A baffle is installed at the gap between the first bent plate and the first corrugated plate, and at the gap between the second bent plate and the first corrugated plate. The baffle blocks the gap, preventing impurities from flowing into the gap, thereby avoiding the problem of spoilage and odor. Third, by using corrugated plate one, corrugated plate two, and long strips in combination, the residues attached to the opposite surfaces of corrugated plate one and corrugated plate two are cleaned, which greatly reduces the contact area during scraping, thereby improving the effect of removing impurities. At the same time, the long strips can also serve as reinforcing ribs for corrugated plate one and corrugated plate two, which helps to improve the structural stability of corrugated plate one and corrugated plate two, reduce the degree of bending and deformation of corrugated plate one and corrugated plate two due to water pressure, thereby ensuring the stability of the shape of the sedimentation channel and ensuring the sedimentation separation effect. Fourth, filter screens are installed between the round rods to intercept impurities and prevent them from flowing to the right side of the second bending plate, thus ensuring the separation effect of impurities. In addition, there are multiple rows of filter screens, which are distributed above and on the side of the corresponding channels. In this way, each filter screen will only intercept a small amount of impurities, reducing the probability of clogging and thus reducing the frequency of maintenance. Attached Figure Description

Detailed Implementation

[0017] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0018] Example 1: A high-efficiency coagulation sedimentation wastewater treatment device for recycled paper production, such as... Figures 1-6As shown, the enclosure includes a housing 1 and a partition 2; the partition 2 is fixedly connected inside the housing 1; it also includes a partition 3, a bent plate 4, a bent plate 5, a corrugated plate 6, a corrugated plate 7, a drive assembly, a stirring assembly, and an inlet / outlet assembly; the partition 3 is fixedly connected to the inside of the housing 1; the bent plate 4 is fixedly connected to the inside of the housing 1; the bent plate 5 is fixedly connected to the inside of the housing 1; several corrugated plates 6 are fixedly connected to the inside of the housing 1; the drive assembly is connected to the housing 1; several corrugated plates 7 are connected to the drive assembly, and the corrugated plates 7 and corrugated plates 6 are alternately distributed; the stirring assembly is connected to the housing 1; the inlet / outlet assembly is connected to the housing 1.

[0019] The drive assembly includes an electric slide rail 201, an electric slider 202, a connecting plate 203, an electric slide rail 204, an electric slider 205, a connecting plate 206, and round rods 207. Two electric slide rails 201 are bolted to the housing 1. Two electric sliders 202 are slidably connected to each electric slide rail 201. All electric sliders 202 are fixedly connected to a connecting plate 203, which is made of alloy material. Two electric slide rails 204 are fixedly connected to the connecting plate 203. Two electric sliders 205 are slidably connected to each electric slide rail 204. All electric sliders 205 are fixedly connected to a connecting plate 206, which is made of alloy material. Several round rods 207 are fixedly connected to the connecting plate 206, and each round rod 207 is fixedly connected to a corresponding corrugated plate 207.

[0020] The stirring assembly includes a motor 208, a transmission rod 209, and an impeller 2010; two motors 208 are bolted to the housing 1; a transmission rod 209 is fixedly connected to the output end of each motor 208, and the transmission rod 209 is made of alloy material; an impeller 2010 is fixedly connected to each transmission rod 209, and the wastewater is stirred by the impeller 2010.

[0021] The sludge inlet and outlet assembly includes pipe 1 2011, pipe 2 2012, and pipe 3 2013; pipe 1 2011 is connected to and fixed to the tank 1, through which sewage is transported into the tank 1; pipe 2 2012 is connected to and fixed to the tank 1, through which sewage is discharged from the tank 1; pipe 3 2013 is connected to and fixed to the tank 1, through which flocs are discharged from the tank 1.

[0022] First, connect the inlet pipe to pipe 2011, the outlet pipe to pipe 2012, and the sewage pipe to pipe 3013. Sewage is then transported to pipe 2011 through the inlet pipe. The sewage flows into the tank 1 through pipe 2011, then flows from below partition 2 to its right side, then from above partition 3 to its right side, then enters and flows upward along the inclined channel between corrugated plate 6 and corrugated plate 7, then flows from above bent plate 5 to its right side, then flows into the outlet pipe through pipe 2012, and finally exits through the outlet pipe. During this process, coagulant is added to the left side of partition 2 and flocculant is added to the right side of partition 2 using an external feeding device. Two motors 208 are started, and the motors 208 drive the transmission rod 20. Rotating the transmission rod 209 drives the impeller 2010 to rotate, which stirs the sewage, allowing it to fully react with the coagulant and flocculant to form flocs. The flocs flow with the sewage to the right side of the partition 2 3. Large flocs settle to the bottom of the tank 1, while small flocs flow with the sewage to the channel between the corrugated plate 1 6 and the corrugated plate 2 7. The inclined channel greatly shortens the settling distance of the small flocs, allowing them to settle quickly and adhere to the lower surface of the channel. They then slide down the inclined surface to the bottom of the tank 1, thus accelerating the settling time of the small flocs. The settled upper layer of sewage overflows the bent plate 2 5 and flows to its right side. Then, it flows through the pipe 2 2012 and the outlet pipe to the next stage of sewage treatment equipment, completing the sewage coagulation and sedimentation operation.

[0023] During regular cleaning, activate electric slide rail 1 201, electric slider 1 202, electric slide rail 2 204, and electric slider 2 205. Electric slider 1 202 drives connecting plate 1 203 to move left and right, while electric slider 2 205 drives connecting plate 2 206 to move forward and backward. This causes connecting plate 2 206 to drive round rod 207 to move in multiple directions horizontally. Round rod 207 then drives corrugated plate 2 7 to move. Figure 4 and Figure 5For example, the right sides of corrugated plate 6 and corrugated plate 7 are settling surfaces. Corrugated plate 7 moves back and forth while simultaneously moving to the left, causing its left side to scrape against the right side of corrugated plate 6. This removes impurities adhering to the right side of corrugated plate 6. Then, while moving back and forth, corrugated plate 7 also moves to the right, causing its right side to scrape against the left side of corrugated plate 6. This removes impurities adhering to the right side of corrugated plate 7. Impurities adhering to the settling surfaces of corrugated plate 6 and corrugated plate 7 are scraped off, preventing problems such as flocculation and blockage. During use, the movable setting of corrugated plate 7 allows corrugated plate 6 and corrugated plate 7 used for settling to scrape against each other, cleaning the impurities adhering to the settling surfaces of corrugated plate 6 and corrugated plate 7, preventing flocculation and blockage. There is no need to use other tools to clean each settling channel one by one, thus greatly improving the maintenance efficiency of the equipment.

[0024] It also includes baffle 1 2014; two baffles 1 2014 are fixedly connected between the bent plate 1 4 and the corresponding corrugated plate 1 6; two baffles 1 2014 are fixedly connected between the bent plate 2 5 and the corresponding corrugated plate 1 6.

[0025] The corrugated plates adjacent to the first bent plate 4 and the second bent plate 5 cannot participate in the cleaning operation. Impurities will block the gaps between the first bent plate 4 and the first corrugated plate 6, as well as between the second bent plate 5 and the first corrugated plate 6, for a long time, which will cause problems such as deterioration and odor. Therefore, baffles 2014 are installed at the gaps between the first bent plate 4 and the first corrugated plate 6, as well as between the second bent plate 5 and the first corrugated plate 6. The baffles 2014 block the gaps and prevent impurities from flowing into the gaps, thereby avoiding the problem of deterioration and odor.

[0026] It also includes strips 2015; several strips 2015 are fixedly connected to corrugated plate 1 6; several strips 2015 are also fixedly connected to corrugated plate 2 7.

[0027] If the corrugated plates scrape directly against each other, the contact area is large and the scraping effect is relatively low. Therefore, long strips 2015 are provided on corrugated plate 6 and corrugated plate 7. When corrugated plate 7 moves relative to corrugated plate 6, the long strips 2015 fixed on the surfaces of the two plates intersect to form line contact scraping, which significantly reduces the scraping contact area and thus improves the efficiency of impurity removal. At the same time, the long strips 2015 can also serve as reinforcing ribs for corrugated plate 6 and corrugated plate 7, which helps to improve the structural stability of corrugated plate 6 and corrugated plate 7 and reduce the impact of water pressure on corrugated plate 6 and corrugated plate 7. The degree of bending and deformation caused by the sound is controlled to ensure the orderly conduct of the settling operation. During use, the corrugated plate 16, corrugated plate 27, and strip 2015 work together to clean the settling surfaces of corrugated plate 16 and corrugated plate 27 of residues, greatly reducing the contact area during scraping, thereby improving the effect of removing impurities. At the same time, strip 2015 can also serve as a reinforcing rib for corrugated plate 16 and corrugated plate 27, which helps to improve the structural stability of corrugated plate 16 and corrugated plate 27 and reduce the degree of bending and deformation caused by water pressure, thus ensuring the orderly conduct of the settling operation.

[0028] It also includes a filter screen 2016; a filter screen 2016 is fixed between each pair of adjacent round rods 207, and the upper wastewater is filtered through the filter screen 2016.

[0029] It also includes a second baffle 2017; a second baffle 2017 is fixedly attached to each round rod 207 in the front row and the back row, and the second baffle 2017 is tilted away from the side of the bending plate 25, so as to intercept impurities on the left side of the filter screen 2016; a gap is formed between the second baffle 2017 and the inner wall of the box 1.

[0030] During the settling process, a very small number of impurities may flow upward with the wastewater through the channel between corrugated plate 6 and corrugated plate 7, and then flow from above the bent plate 5 to its rear side, resulting in incomplete settling. Therefore, a filter screen 2016 is installed between the round rods 207 to intercept the impurities and prevent them from flowing to the right side of the bent plate 5, thus ensuring the impurity separation effect. The filter screens 2016 are arranged in multiple rows and distributed above and beside the corresponding channels. In this way, each filter screen 2016 will only intercept a small amount of impurities on its side, reducing the probability of clogging and thus reducing the frequency of maintenance. During this process, the baffle 2017 can effectively block impurities from bypassing the lateral edge (i.e., the front-to-back direction) of the filter screen 2016, ensuring that all wastewater flowing to the bent plate 5 must be filtered by the filter screen 2016, thereby ensuring the interception effect.

[0031] Example 2, based on Example 1, such as Figure 6As shown, it also includes a cleaning component, which includes a pipe 2018 and a nozzle 2019; the pipe 2018 is fixedly connected to the connecting plate 206; and several nozzles 2019 are connected to and fixedly connected to the pipe 2018.

[0032] The impeller 2010 is coated with an anti-corrosion coating to improve its lifespan.

[0033] First, connect the external flushing water pipe to pipe 4 2018. During regular maintenance, high-pressure clean water is supplied to pipe 4 2018 through this flushing water pipe. The clean water flows into nozzle 2019 through pipe 4 2018 and is then sprayed forward or backward from nozzle 2019, thereby washing away the impurities attached to the surface of filter screen 2016 to the front or rear inner side of the box 1. A gap is formed between baffle 2 2017 and the inner wall of box 1. Then, a manual retrieval net can be inserted through the gap to retrieve and remove the impurities.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
