Description

[0001] This invention relates to the field of wastewater treatment, and more particularly to a workshop cutting wastewater filtration and treatment device. Background Technology

[0002] Stone cutting workshops generate a large amount of cutting wastewater, which contains a large number of particulate matter (large particles are usually larger than 100 micrometers in diameter, medium particles are generally between 10 and 100 micrometers in diameter, and small particles are smaller than 10 micrometers in diameter). If the wastewater is discharged directly, it will cause serious environmental pollution. At the same time, the particulate matter in the wastewater will be wasted and cannot be reused.

[0003] Existing technologies, such as Chinese Patent No. CN217312339U (a green mining stone cutting wastewater recycling device) and Chinese Patent No. CN210645477U (a green mining stone cutting wastewater recycling device), although they disclose the treatment of stone cutting wastewater, cannot specifically treat large, medium and small particles in the wastewater. Summary of the Invention

[0004] In order to overcome the shortcomings of existing technologies that cannot specifically treat large, medium and small particles in stone cutting wastewater, this invention provides a workshop cutting wastewater filtration and treatment device.

[0005] A workshop cutting wastewater filtration and treatment device includes a settling tank;

[0006] The settling tank has multiple settling chambers, and a flocculation tank with multiple flocculation chambers is installed at the bottom of the settling tank. Each settling chamber is connected to the flocculation chamber through a guide pipe, and an electric valve is installed at the top of the guide pipe. A wastewater circulation conveying assembly is installed on the settling tank to orderly inject workshop stone cutting wastewater into the settling chambers. An inclined filter screen is detachably connected to the upper side of the settling chamber. A translation and lifting assembly is installed on the outer side of the settling chamber, and a first mounting plate is installed on the moving part of the translation and lifting assembly. Multiple agitators are installed on the first mounting plate to agitate the particles.

[0007] Furthermore, a drain plate is detachably connected to the bottom of the settling chamber.

[0008] Furthermore, an upper water pipe and a lower water pipe are installed at the bottom of the flocculation chamber.

[0009] Furthermore, the wastewater circulation and conveying assembly includes an annular guide rail, a first electric slider, a wastewater conveying pipe, and a wastewater equalization nozzle; an annular guide rail is installed on the top of the settling tank, and a first electric slider is slidably connected to the annular guide rail; a wastewater conveying pipe is fixedly connected to the first electric slider; the wastewater conveying pipe is connected to the wastewater equalization nozzle, through which wastewater is sprayed onto the inclined filter screen.

[0010] Furthermore, the translation and lifting assembly includes a horizontal guide rail, a second electric slider, a second mounting plate, a vertical guide rail, and a third electric slider; a horizontal guide rail is installed on the side of the settling chamber; a second electric slider is slidably connected to the horizontal guide rail; a second mounting plate is fixedly connected to the second electric slider; a vertical guide rail is installed on the second mounting plate; a third electric slider is slidably connected to the vertical guide rail, and the third electric slider is fixedly connected to the first mounting plate.

[0011] Furthermore, by connecting the upper water pipe to the flocculant and sending it into the equipment, the flocculant is injected into the flocculation chamber. By connecting the lower water pipe to the air pumping equipment, air is pumped into the flocculation chamber.

[0012] Furthermore, the mixer has a flat mixing section, which cleans the inclined filter screen by rotating all the mixing sections to a horizontal position.

[0013] Furthermore, it also includes a baffle and a backwash plate; a baffle is fixed to the inner side of the settling chamber, and the baffle is located below the inclined filter screen; a backwash plate is installed on the baffle, and the backwash plate is connected to a water supply pipe.

[0014] Furthermore, it also includes a second electric push rod, a rectangular channel, a connecting frame, a third electric push rod, and a receiving plate; the second electric push rod is installed on the side of the settling chamber; the rectangular channel is installed on the telescopic part of the second electric push rod, and the rectangular channel is movably connected to the settling chamber; the third electric push rod is fixedly connected to the rectangular channel through the connecting frame; the receiving plate is fixedly connected to the telescopic part of the third electric push rod, and the receiving plate is slidably connected to the rectangular channel.

[0015] Furthermore, there are multiple water-permeable gaps between the two sides of the baffle and the settling chamber.

[0016] Furthermore, it also includes a first electric push rod and a movable plate; the first electric push rod is installed at the bottom of the backwash plate; the movable plate is fixedly connected to the telescopic part of the first electric push rod. Beneficial effects

[0017] This invention addresses wastewater from stone cutting by directly filtering and intercepting large particles using an inclined filter screen. The inclined design of the screen encourages large particles to gather towards the right-side stirring section, reducing their residence time on the screen and preventing blockages. This ensures continuous and efficient filtration. Simultaneously, the mixer drives the stirring section to rotate, while a third electric slider moves the stirring section up and down, continuously agitating the large particles gathered on the right side of the screen. This allows the entrained medium and small particles to be carried away by the continuously sprayed wastewater to the settling chamber, significantly improving separation purity. The medium and small particles then follow the wastewater filtered by the inclined screen into the settling chamber, where they undergo stratification through static settling. The height design of the guide pipe ensures that only the upper layer containing small particles enters the flocculation chamber, while the lower layer contains medium particles. The settling layer is stored separately and removed by workers. The design of the wastewater circulation and conveying components and guide pipes enables continuous and convenient operation of filtration, settling, and flocculation in the same equipment. At the same time, after small particles enter the flocculation chamber with the wastewater, they are mixed by injecting flocculant and pumping in air to promote flocculation into agglomerates, and finally extracted and processed in layers. The present invention also overcomes the problems of CN217312339U, which only uses fixed and movable filter screens for single filtration and cannot distinguish between large, medium and small particles, and can only achieve coarse solid-liquid separation; and CN210645477U, which, although it sets up a settling box and filter media layer, does not classify particles by size during the settling and filtration process, and small and medium particles are easily mixed with large particles, making it impossible to achieve precise separation.

[0018] This invention effectively removes clogging particles from the inclined filter screen by combining the scraping action of the flat stirring part (with bristles) of the mixer with the flushing action of the backwash plate, thus preventing filter screen clogging and a decrease in filtration efficiency. At the same time, by using the linkage between the receiving plate and the rectangular channel, large particles are temporarily stored in the rectangular channel during cleaning, preventing them from covering the inclined filter screen and affecting the cleaning effect, further improving the thoroughness of filter screen cleaning and ensuring continuous and efficient filtration.

[0019] This invention uses a baffle in the settling chamber to receive filtered wastewater, allowing the wastewater to flow down the inner wall through the water-permeable gap between the baffle and the settling chamber. This avoids impacting the collected wastewater, reduces agitation, and shortens the settling time. Furthermore, the gap on the right side of the baffle can be adjusted by a movable plate to ensure efficient water flow when the wastewater impact speed is high, prevent water accumulation on the baffle, and ensure a stable and orderly settling process.

Detailed Implementation

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: A workshop cutting wastewater filtration and treatment device, such as Figures 1-11 As shown, it includes a settling box 1;

[0034] The settling tank 1 has multiple settling chambers 1a, and a flocculation tank 2 is installed at the bottom of the settling tank 1. The flocculation tank 2 has multiple flocculation chambers 2a. Each settling chamber 1a is connected to a flocculation chamber 2a through a guide pipe 4, and an electric valve is provided at the upper part of the guide pipe 4. There are 6 settling chambers 1a and 2 flocculation chambers 2a. Every 3 settling chambers 1a are connected to one flocculation chamber 2a through the guide pipe 4. A wastewater circulation conveying assembly 3 is installed on the settling tank 1 to orderly inject workshop stone cutting wastewater into the settling chambers 1a. An inclined filter screen 5 is detachably connected to the upper side of the settling chamber 1a, and the wastewater washes on the inclined filter screen 5. A translation and lifting assembly 6 is installed on the outside of the settling chamber 1a. A first mounting plate 7 is installed on the moving part of the translation and lifting assembly 6. Multiple agitators 8 are installed on the first mounting plate 7 to agitate the particles.

[0035] The bottom of the settling chamber 1a is detachably connected to a drain plate 1aa.

[0036] The bottom of the flocculation chamber 2a is equipped with an upper water pipe 2aa and a lower water pipe 2ab.

[0037] The wastewater circulation and conveying assembly 3 includes an annular guide rail 31, a first electric slider 32, a wastewater conveying pipe 33, and a wastewater equalization nozzle 34; the annular guide rail 31 is installed on the top of the settling tank 1, and the first electric slider 32 is slidably connected to the annular guide rail 31; the wastewater conveying pipe 33 is fixedly connected to the first electric slider 32; the wastewater conveying pipe 33 is connected to the wastewater equalization nozzle 34, and the wastewater is sprayed onto the inclined filter screen 5 through the wastewater equalization nozzle 34.

[0038] The translation and lifting assembly 6 includes a horizontal guide rail 61, a second electric slider 62, a second mounting plate 63, a vertical guide rail 64, and a third electric slider 65; the horizontal guide rail 61 is installed on the side of the settling chamber 1a; the second electric slider 62 is slidably connected to the horizontal guide rail 61; the second mounting plate 63 is fixedly connected to the second electric slider 62; the vertical guide rail 64 is installed on the second mounting plate 63; the third electric slider 65 is slidably connected to the vertical guide rail 64, and the third electric slider 65 is fixedly connected to the first mounting plate 7.

[0039] When this invention is working, as Figure 2 , Figure 4As shown, wastewater from the stone cutting workshop is collected and pumped into wastewater delivery pipe 33. The wastewater contains a large amount of large particles (typically larger than 100 micrometers in diameter, treated by filtration), medium particles (generally between 10-100 micrometers in diameter, treated by sedimentation), and small particles (smaller than 10 micrometers in diameter and difficult to settle, treated by flocculation). The wastewater is then sent through wastewater delivery pipe 33 to wastewater distribution nozzles 34, where it is sprayed onto inclined filter screen 5. The inclined filter screen 5 filters and intercepts the large particles in the wastewater, such as… Figure 6 As shown, the large particles filtered move to the right and accumulate at the stirring section 8a. By setting the inclined filter screen 5 to tilt to the right, the residence time of large particles on the upper side of the inclined filter screen 5 can be reduced, the upper side of the inclined filter screen 5 can be exposed to filter subsequent wastewater, the filtration effect of wastewater can be improved, and the large particles can be accumulated on the right side of the inclined filter screen 5 for easy removal later.

[0040] Furthermore, considering that the wastewater sprayed from the wastewater distribution nozzle 34 will continuously wash the inclined filter screen 5, some wastewater will directly shift to the right without being filtered, causing medium and small particles in the wastewater to be carried to the right along with large particles, resulting in poor wastewater separation and filtration. At this time, the agitator 8 is controlled to drive the agitator 8a to rotate, using multiple agitators 8a to stir the particles, making the particles move continuously, which, together with the continuously sprayed wastewater, carries the medium and small particles to the settling chamber 1a. Further, such as... Figure 8 As shown, the third electric slider 65 can be controlled to move up and down on the vertical guide rail 64, thereby driving the mixer 8 to move up and down through the first mounting plate 7. The up and down movement of the mixing part 8a can more efficiently agitate the particles and improve the separation effect of particles and small particles in the wastewater. The large particles obtained by filtration can be reused in projects such as roadbed filling, site leveling, and retaining wall construction.

[0041] Afterwards, the wastewater filtered by the inclined filter screen 5 enters the settling chamber 1a. When the settling chamber 1a is filled with a preset volume of wastewater (for example, the wastewater reaches 2 / 3 of the volume of the settling chamber 1a), the injection of wastewater into the settling chamber 1a is stopped, allowing the wastewater in the settling chamber 1a to settle and settle the medium particulate matter in the wastewater. The medium particulate matter obtained from the settling can be reused as fine aggregate in mortar and plastering materials, or used in the production of lightweight concrete blocks, autoclaved bricks, etc.

[0042] After the settling chamber 1a is filled with a predetermined volume of wastewater, as follows: Figure 2 , Figure 4 As shown, the first electric slider 32 is controlled to move on the annular guide rail 31, thereby driving the wastewater equalization nozzle 34 to move towards the next inclined filter screen 5. While the particles in the previous settling chamber 1a are settling, wastewater is injected into the next settling chamber 1a.

[0043] After the medium-sized particles in the settling chamber 1a have settled, the settling chamber 1a is divided into upper and lower layers. The upper liquid contains free small particles, and the lower settling layer contains medium-sized particles. At this time, the electric valve at the top of the guide pipe 4 can be opened. Since the upper opening of the guide pipe 4 is higher than the bottom of the settling chamber 1a by a certain distance (the specific height of the upper opening of the guide pipe 4 is set according to the thickness of the settling layer of medium-sized particles, which is determined by the content of medium-sized particles, and the content of medium-sized particles is determined by the volume of wastewater sent into the settling chamber 1a each time), when the electric valve is opened, the wastewater flows down into the flocculation box 2 through the guide pipe 4, realizing the direct transfer of wastewater. The settling layer of medium-sized particles remains in the settling chamber 1a. The workers can remove the settling layer of medium-sized particles by disassembling the drain plate 1aa and reuse it.

[0044] Afterwards, when the wastewater enters the flocculation chamber 2a through the guide pipe 4 and completes flocculation, the flocculation chamber 2a is divided into upper and lower layers. The upper layer of liquid is pumped away by connecting the upper water pipe 2aa, and then the lower layer of flocculents is pumped away by connecting the lower water pipe 2ab.

[0045] By connecting the upper water pipe 2aa to the flocculant and injecting it into the flocculation chamber 2a, and by connecting the lower water pipe 2ab to the air pumping device, air is pumped into the flocculation chamber 2a. The bubble disturbance enhances the contact between the flocculant and small particles, accelerates the aggregation of colloidal particles, and improves the contact effect between the flocculant and the wastewater.

[0046] As can be seen from the above, when dealing with wastewater from stone cutting, the present invention directly filters and intercepts large particles using an inclined filter screen 5. The inclined design of the inclined filter screen 5 causes large particles to gather towards the right-side stirring section 8a, reducing their residence time on the inclined filter screen 5, avoiding accumulation and clogging, and ensuring continuous and efficient filtration. At the same time, the stirrer 8 drives the stirring section 8a to rotate, and the third electric slider 65 moves the stirring section 8a up and down, causing the large particles gathered on the right side of the inclined filter screen 5 to continuously tumble, allowing the entrained medium and small particles to be carried away by the continuously sprayed wastewater to the settling chamber 1a, significantly improving the separation purity. The medium and small particles follow the wastewater filtered by the inclined filter screen 5 into the settling chamber 1a, where they achieve stratification through static settling. The height design of the guide pipe 4 ensures that only the upper layer of liquid containing small particles enters the flocculation chamber. In the flocculation chamber 2a, the lower particulate sedimentation layer is stored separately and removed by workers. The design of the wastewater circulation conveying component 3 and the guide pipe 4 enables continuous and convenient operation of filtration, sedimentation, and flocculation in the same equipment. At the same time, after small particles enter the flocculation chamber 2a with the wastewater, they are mixed by injecting flocculant and pumping in air to promote flocculation into agglomerates, and finally extracted and processed in layers. The present invention also overcomes the problems of CN217312339U, which only uses fixed and movable filter screens for single filtration and cannot distinguish between large, medium and small particles, and can only achieve coarse solid-liquid separation; and CN210645477U, which, although equipped with a sedimentation box and filter media layer, does not classify particles by size during sedimentation and filtration, and small and medium particles are easily mixed with large particles, making it impossible to achieve precise separation.

[0047] The mixer 8 has a flat mixing section 8a and a brush at the bottom. By rotating all the mixing sections 8a to a horizontal position, the inclined filter screen 5 is cleaned.

[0048] It also includes a baffle 101 and a backwash plate 102; a baffle 101 is fixedly connected to the inner side of the settling chamber 1a, and the baffle 101 is located below the inclined filter screen 5; a backwash plate 102 is installed on the baffle 101, and the backwash plate 102 is connected to a water supply pipe.

[0049] Furthermore, when the filtration effect of the inclined filter screen 5 deteriorates and it needs to be cleaned, all the stirring parts 8a can be rotated to a horizontal position, such as... Figure 7As shown, the translation and lifting assembly 6 is then controlled to drive the stirring part 8a to move back and forth against the upper side of the inclined filter screen 5 (specifically, the second electric slider 62 moves horizontally on the horizontal guide rail 61, and the third electric slider 65 moves vertically on the vertical guide rail 64 to drive the stirring part 8a to move in an inclined manner; this is existing technology and will not be described in detail here). The reciprocating movement of the stirring part 8a scrapes away the clogging particles on the upper side of the inclined filter screen 5. At the same time, the backwash plate 102 located on the lower side of the inclined filter screen 5 is controlled to flush water upwards to wash away the clogging particles on the inclined filter screen 5. In this way, the cleaning of the inclined filter screen 5 is achieved through the mutual cooperation of the backwash water of the backwash plate 102 and the scraping action of the stirring part 8a.

[0050] like Figures 10-11 As shown, it also includes a second electric push rod 301, a rectangular channel 302, a connecting frame 303, a third electric push rod 304, and a receiving plate 305; the second electric push rod 301 is installed on the side of the settling chamber 1a; the rectangular channel 302 is installed on the telescopic part of the second electric push rod 301, and the rectangular channel 302 is movably connected to the settling chamber 1a; the third electric push rod 304 is fixedly connected to the rectangular channel 302 through the connecting frame 303; the receiving plate 305 is fixedly connected to the telescopic part of the third electric push rod 304, and the receiving plate 305 is slidably connected to the rectangular channel 302.

[0051] Furthermore, such as Figure 10 , Figure 11 During backwashing of the inclined filter screen 5, large particles accumulated on the receiving plate 305 cause the lower right part of the inclined filter screen 5 to be covered by these particles, affecting the impact effect of the water sprayed from the backwash plate 102 and the scraping effect of the stirring section 8a. This significantly weakens the backwashing effect on the inclined filter screen 5. To address this problem, the third electric push rod 304 of this invention is controlled to push the receiving plate 305 downwards, moving it to the underside of the rectangular channel 302. This allows the large particles to be temporarily stored within the rectangular channel 302. This avoids large particles from contacting the inclined filter 5 during backwashing, which would affect the backwashing effect. When it is time to remove large particles, the second electric push rod 301 can be controlled to push the rectangular channel 302, the connecting frame 303, the third electric push rod 304, and the receiving plate 305 downward as a whole. At the same time, the third electric push rod 304 simultaneously pushes the receiving plate 305 upward to expose the large particles, which can then be removed by workers. As the rectangular channel 302 moves downward, the receiving plate 305 moves upward simultaneously, thus exposing the large particles without them coming into contact with the inclined filter 5.

[0052] like Figure 9 As shown, there are multiple water-permeable gaps between the two sides of the baffle 101 and the settling chamber 1a.

[0053] It also includes a first electric push rod 201 and a movable plate 202; the first electric push rod 201 is installed at the bottom of the backwash plate 102; the movable plate 202 is fixedly connected to the telescopic part of the first electric push rod 201.

[0054] Furthermore, when the wastewater distribution nozzle 34 sprays wastewater onto the inclined filter screen 5 to filter large particles, in order to shorten the settling time of the wastewater in the settling chamber 1a, it is necessary to avoid the wastewater already collected in the settling chamber 1a being agitated or subjected to water impact. At this time, the wastewater filtered from the inclined filter screen 5 is received by the baffle 101. Figure 9 As shown, the wastewater on the baffle 101 flows down into the settling chamber 1a through the gaps between its front and rear sides and the settling chamber 1a, following the inner wall of the settling chamber 1a, thus preventing impact on the existing wastewater in the settling chamber 1a. At the same time, the gap between the right side of the baffle 101 and the settling chamber 1a can be controlled by moving the moving plate 202 by controlling the first electric push rod 201 to control the size of the gap on the right side, so as to ensure the water flow efficiency when the water sprayed from the wastewater distribution nozzle 34 is fast, and avoid insufficient water flow capacity in the gap, which would cause more and more water to accumulate on the baffle 101.

[0055] As can be seen from the above, the present invention effectively removes clogging particles from the inclined filter screen 5 by combining the scraping action of the flat stirring part 8a (with bristles) of the mixer 8 with the flushing action of the backwash plate 102, thus preventing the filter screen from becoming clogged and reducing filtration efficiency. Simultaneously, by leveraging the linkage between the receiving plate 305 and the rectangular channel 302, large particles are temporarily stored through the rectangular channel 302 during cleaning, preventing them from covering the inclined filter screen 5 and affecting the cleaning effect, further improving the thoroughness of filter screen cleaning and ensuring continuous and efficient filtration. The baffle 101 in the settling chamber 1a receives the filtered wastewater, allowing the wastewater to flow down the inner wall through the water-passing gap between the baffle 101 and the settling chamber 1a, avoiding impact on the collected wastewater, reducing agitation, and thus shortening the settling time. Furthermore, the gap on the right side of the baffle 101 can be adjusted by the moving plate 202 to ensure water flow efficiency when the wastewater impact speed is high, preventing water accumulation on the baffle 101 and ensuring a stable and orderly settling process.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
