[0016] When the present invention faces stone cutting wastewater, large particles are directly filtered and intercepted by the inclined filter screen. The inclined design of the inclined filter screen prompts large particles to gather to the right stirring part, reducing the residence time on the inclined filter screen, avoiding accumulation and clogging of the inclined filter screen, and ensuring continuous and efficient filtration. At the same time, the mixer is controlled to drive the stirring part to rotate, and the third electric slider is used to drive the stirring part to move up and down, so that the large particles gathered on the right side of the inclined filter screen are continuously turned over, and the entrained medium and small particles are taken away to the sedimentation chamber by the continuously ejected wastewater, which significantly improves the separation purity; the medium and small particles follow the wastewater filtered by the inclined filter screen into the sedimentation chamber, and stratification is achieved by static sedimentation. The height design of the guide pipe ensures that only the liquid containing small particles in the upper layer enters the flocculation chamber, and the medium particles in the lower layer are The sedimentation layer is retained separately for workers to take out, and the design of the wastewater circulation conveying component and the guide pipe can realize the continuous and convenient operation of filtration, sedimentation and flocculation in the same equipment; at the same time, after the small particles enter the flocculation chamber with the wastewater, the flocculant is injected and the air is pumped in to enhance the mixing, so that the small particles are flocculated into agglomerates, and finally extracted and processed in layers; the present invention also overcomes the problem that CN217312339U only performs a single filtration through a fixed filter screen and a movable filter screen, cannot distinguish between large, medium and small particles, and can only achieve rough separation of solid and liquid; although CN210645477U is provided with a sedimentation box and a filter material layer, the sedimentation and filtration process does not classify the particle size, and small and medium particles are easily mixed in the large particles, and accurate separation cannot be achieved.

[0017] The present invention can effectively remove clogged particles on the inclined filter screen through the scraping action of the straight stirring part (with bristles) of the mixer and the flushing of the backwash plate, thereby avoiding clogging of the filter screen and resulting in a decrease in filtration efficiency; at the same time, with the help of the linkage between the receiving plate and the rectangular channel, large particles are temporarily stored through the rectangular channel during cleaning, preventing them from covering the inclined filter screen and affecting the cleaning effect, further improving the thoroughness of the filter screen cleaning and ensuring continuous and efficient filtration.

[0018] The present invention receives the filtered wastewater through the baffle in the sedimentation chamber, so that the wastewater flows down along the inner wall through the water-passing gap between the baffle and the sedimentation chamber, avoiding impact on the collected wastewater, reducing agitation, and thus shortening the sedimentation time; and the gap on the right side of the baffle can be adjusted in size by a movable plate, ensuring water flow efficiency when the wastewater impact speed is fast, preventing water accumulation on the baffle, and ensuring a stable and orderly sedimentation process.

DETAILED DESCRIPTION

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: A workshop cutting wastewater filtration and treatment equipment, such as Figures 1-11 As shown, it includes a sedimentation box 1; The sedimentation box 1 has multiple sedimentation chambers 1a, and a flocculation box 2 is installed at the bottom of the sedimentation box 1. The flocculation box 2 has multiple flocculation chambers 2a; each sedimentation chamber 1a is connected to the flocculation chamber 2a through a guide pipe 4, and an electric valve is provided on the upper part of the guide pipe 4; among them, there are 6 sedimentation chambers 1a and 2 flocculation chambers 2a, and every 3 sedimentation chambers 1a are connected to a flocculation chamber 2a through the guide pipe 4; the sedimentation box 1 is equipped with a wastewater circulation and conveying component 3 for orderly injecting workshop stone cutting wastewater into the sedimentation chamber 1a; the upper side of the sedimentation chamber 1a is detachably connected to an inclined filter screen 5, and the wastewater is flushed on the inclined filter screen 5; the outside of the sedimentation chamber 1a is equipped with a translation and lifting component 6, and the moving part of the translation and lifting component 6 is equipped with a first mounting plate 7; multiple mixers 8 are installed on the first mounting plate 7, and the particulate matter is stirred by the mixer 8.

[0023] A sewage discharge plate 1aa is detachably connected to the bottom of the sedimentation chamber 1a.

[0024] An upper water pipe 2aa and a lower water pipe 2ab are installed at the bottom of the flocculation chamber 2a.

[0025] 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 equalizing nozzle 34; an annular guide rail 31 is installed on the top of the sedimentation box 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 equalizing nozzle 34, and the wastewater is sprayed onto the inclined filter 5 through the wastewater equalizing nozzle 34.

[0026] 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 sedimentation chamber 1a; the second electric slider 62 is slidably connected to the horizontal guide rail 61; the second mounting plate 63 is fixed 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 fixed to the first mounting plate 7.

[0027] When the present invention works, Figure 2 、 Figure 4 As shown, the wastewater generated by the stone cutting workshop is collected and injected into the wastewater delivery pipe 33 through a pump. The wastewater contains a large amount of large particles (particle size is usually greater than 100 microns, which are treated by filtration), medium particles (particle size is generally between 10-100 microns, which are treated by sedimentation) and small particles (particle size is less than 10 microns and difficult to settle, which are treated by flocculation). The wastewater is sent to the wastewater equalization nozzle 34 through the wastewater delivery pipe 33 and sprayed on the inclined filter 5. The large particles in the wastewater are filtered and intercepted by the inclined filter 5, as shown in FIG. Figure 6In the orientation shown, the filtered large particles move to the right and accumulate at the stirring portion 8a. By setting the inclined filter screen 5 to be inclined to the right, the residence time of the large particles on the upper side of the inclined filter screen 5 can be reduced, exposing the upper side of the inclined filter screen 5 to filter subsequent wastewater, thereby improving the filtration effect of the wastewater and allowing the large particles to accumulate on the right side of the inclined filter screen 5 for subsequent removal. Furthermore, considering that the wastewater sprayed from the wastewater equalizing nozzle 34 will continuously flush the inclined filter 5, some wastewater will be directly transferred to the right without being filtered, causing the medium and small particles in the wastewater to be entrained in the large particles and transferred to the right, resulting in poor wastewater separation and filtration effect. At this time, the mixer 8 is controlled to drive the stirring part 8a to rotate, and multiple stirring parts 8a are used to stir the particles here, so that the particles are constantly moving, and the medium and small particles are taken away to the sedimentation chamber 1a with the help of the continuously sprayed wastewater. Further, as Figure 8 As shown, the third electric slider 65 can be controlled to move back and forth up and down on the vertical guide rail 64, thereby driving the mixer 8 to move back and forth up and down through the first mounting plate 7, and utilizing the up and down movement of the stirring part 8a to stir the particles more efficiently, thereby improving 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.

[0028] Afterwards, the wastewater filtered by the inclined filter 5 enters the sedimentation chamber 1a. When a preset volume of wastewater is injected into the sedimentation chamber 1a (for example, the wastewater reaches 2 / 3 of the volume of the sedimentation chamber 1a), the injection of wastewater into the sedimentation chamber 1a is stopped, and the wastewater in the sedimentation chamber 1a is allowed to settle, and the medium particles in the wastewater are settled; the medium particles obtained by settling can be reused as fine aggregates for mortar and plastering materials, or used to produce lightweight concrete blocks, autoclaved bricks, etc.

[0029] After the settling chamber 1a is filled with a preset volume of wastewater, 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 evenly distributing nozzle 34 to move toward the next inclined filter 5, while the particles in the previous settling chamber 1a are settled, and wastewater is injected into the next settling chamber 1a; Afterwards, after the medium particles in the sedimentation chamber 1a have been settled, the sedimentation chamber 1a is divided into upper and lower layers, with the upper layer containing free small particles and the lower layer containing medium particles. At this time, the electric valve on the upper part of the guide pipe 4 can be controlled to open. Since the upper opening of the guide pipe 4 is higher than the bottom of the sedimentation 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 sedimentation layer of medium particles, which is determined by the content of medium particles, and the content of medium particles is determined by the volume of wastewater fed into the sedimentation chamber 1a each time), when the electric valve is opened, the wastewater flows downward through the guide pipe 4 into the flocculation box 2, realizing direct transfer of the wastewater, while the sedimentation layer of medium particles remains in the sedimentation chamber 1a. The workers remove the sewage plate 1aa and take out the sedimentation layer of medium particles for reuse. Afterwards, when the wastewater enters the flocculation chamber 2a through the diversion pipe 4 and flocculation is completed, 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 flocculants is pumped away by connecting the lower water pipe 2ab.

[0030] By connecting the upper water pipe 2aa to the flocculant feeding equipment, the flocculant is injected into the flocculation chamber 2a. By connecting the lower water pipe 2ab to the air pumping equipment, air is pumped into the flocculation chamber 2a. The bubble disturbance is used to enhance the contact between the flocculant and small particles, accelerate the aggregation of colloidal particles, and improve the contact effect between the flocculant and wastewater.

[0031] As can be seen from the above, when the present invention faces stone cutting wastewater, large particles are directly filtered and intercepted by the inclined filter screen 5. The inclined design of the inclined filter screen 5 prompts large particles to gather to the right stirring part 8a, reducing the residence time on the inclined filter screen 5, avoiding accumulation and clogging of the inclined filter screen 5, and ensuring continuous and efficient filtration. At the same time, the mixer 8 is controlled to drive the stirring part 8a to rotate, and the third electric slider 65 is used to drive the stirring part 8a to move up and down, so that the large particles gathered on the right side of the inclined filter screen 5 are continuously turned over, and the entrained medium and small particles are taken away to the sedimentation chamber 1a by the continuously ejected wastewater, which significantly improves the separation purity; the medium and small particles follow the wastewater filtered by the inclined filter screen 5 into the sedimentation chamber 1a, and stratification is achieved by static sedimentation. The height design of the guide pipe 4 ensures that only the upper layer of liquid containing small particles enters the flocculent layer. In the coagulation chamber 2a, the particle sedimentation layer in the lower layer is retained separately for workers to take out, and the design of the wastewater circulation conveying component 3 and the guide pipe 4 can realize the continuous and convenient operation of filtration, sedimentation and flocculation in the same equipment; at the same time, after the small particles enter the flocculation chamber 2a with the wastewater, the small particles are flocculated into agglomerates by injecting flocculants and pumping in air to enhance mixing, and finally extracted and processed in layers; the present invention also overcomes the problem that CN217312339U only performs single filtration through fixed filter screens and movable filter screens, cannot distinguish between large, medium and small particles, and can only achieve rough separation of solid and liquid; although CN210645477U is equipped with a sedimentation box and a filter material layer, the sedimentation and filtration process does not classify the particle size, and small and medium particles are easily mixed in large particles, and accurate separation cannot be achieved.

[0032] The mixer 8 has a straight mixing portion 8a and a brush at the bottom. By rotating all the mixing portions 8a to a horizontal position, the inclined filter 5 is cleaned.

[0033] It also includes a baffle 101 and a backwash plate 102; the baffle 101 is fixedly connected to the inside of the sedimentation chamber 1a, and the baffle 101 is located below the inclined filter 5; the backwash plate 102 is installed on the baffle 101, and the backwash plate 102 is connected to the water supply pipe.

[0034] Furthermore, when the filtering effect of the inclined filter 5 becomes poor and the inclined filter 5 needs to be cleaned, all the stirring parts 8a can be rotated to a horizontal state, such as Figure 7As shown, the translation and lifting assembly 6 is then controlled to drive the stirring portion 8a to move back and forth obliquely 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 portion 8a to move obliquely. This is the prior art and will not be described in detail here). The clogged particles on the upper side of the inclined filter screen 5 are scraped off by the reciprocating movement of the stirring portion 8a, and at the same time, the backwash plate 102 located on the lower side of the inclined filter screen 5 is controlled to flush water upward to flush away the clogged 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 portion 8a.

[0035] like Figure 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 sedimentation chamber 1a; the telescopic part of the second electric push rod 301 is installed with a rectangular channel 302, and the rectangular channel 302 is movably connected to the sedimentation chamber 1a; the rectangular channel 302 is fixedly connected to the third electric push rod 304 through the connecting frame 303; the telescopic part of the third electric push rod 304 is fixedly connected to the receiving plate 305, and the receiving plate 305 is slidably connected to the rectangular channel 302.

[0036] Furthermore, if Figure 10 、 Figure 11 When the inclined filter screen 5 is backwashed and cleaned, the receiving plate 305 is covered with filtered large particles, which affects the impact effect of the water sprayed by the backwash plate 102 and the scraping effect of the stirring part 8a, thereby greatly weakening the backwash effect of the inclined filter screen 5. To solve this problem, the third electric push rod 304 of the present invention is controlled to push the receiving plate 305 downward, so that the receiving plate 305 moves to the lower side of the rectangular channel 302, and then the filtered large particles can be temporarily stored through the rectangular channel 302. This avoids the situation where large particles come into contact with the inclined filter screen 5 and affect the backwashing effect when the inclined filter screen 5 is backwashed. Later, when the large particles need to be removed, 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 to move downward as a whole. At the same time, the third electric push rod 304 synchronously pushes the receiving plate 305 upward to expose the large particles, and the workers transfer them away. When the rectangular channel 302 moves downward, the receiving plate 305 moves upward synchronously, so that the large particles are exposed and will not come into contact with the inclined filter screen 5.

[0037] like Figure 9 As shown, there are multiple water-permeable gaps between the two sides of the baffle 101 and the sedimentation chamber 1a.

[0038] 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.

[0039] Furthermore, when the wastewater evenly distributing nozzle 34 sprays wastewater to the inclined filter 5 to filter large particles, in order to shorten the sedimentation time of the wastewater in the sedimentation chamber 1a, it is necessary to avoid the wastewater collected in the sedimentation chamber 1a from being stirred or impacted by water as much as possible. At this time, the wastewater filtered from the inclined filter 5 is received by the baffle 101, such as Figure 9 In the orientation shown, the wastewater on the baffle 101 flows downward into the sedimentation chamber 1a along the inner wall of the sedimentation chamber 1a through the water-passing gaps between its front and rear sides and the sedimentation chamber 1a, thereby not causing impact on the wastewater already in the sedimentation chamber 1a; at the same time, the gap between the right side of the baffle 101 and the sedimentation chamber 1a can be controlled by controlling the first electric push rod 201 to push the movable plate 202 to move, so as to control the size of the water-passing gap on the right side, so as to ensure the water flow efficiency when the water sprayed out of the wastewater equalizing nozzle 34 is fast, and to avoid insufficient water-passing capacity of the gap, which leads to more and more water accumulating on the baffle 101.

[0040] As can be seen from the above, the present invention effectively removes clogged particles from the inclined filter 5 by combining the scraping action of the straight stirring portion 8a (with bristles) of the stirrer 8 with the flushing action of the backwash plate 102, thus preventing filter clogging and a decrease in filtration efficiency. Furthermore, by virtue of the linkage between the receiving plate 305 and the rectangular channel 302, large particles are temporarily stored in the rectangular channel 302 during cleaning, preventing large particles from covering the inclined filter 5 and affecting the cleaning effect, further improving the thoroughness of the filter cleaning and ensuring continuous and efficient filtration. The baffle 101 within the sedimentation chamber 1a receives filtered wastewater, allowing it to flow down along the inner wall through the water-passing gap between the baffle 101 and the sedimentation chamber 1a, avoiding impact with the collected wastewater, reducing agitation, and thus shortening the sedimentation time. Furthermore, the right side gap of the baffle 101 can be adjusted in size by the movable plate 202, ensuring efficient water flow when the wastewater impact velocity is high, preventing water accumulation in the baffle 101, and ensuring a stable and orderly sedimentation process.

[0041] 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 the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
