DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0035] In the existing sewage treatment system, there are not only the problems of many pools and large land area, which leads to the waste of factory land resources, but also the large number of operators required to extract the slurry from each pool to the mud press, and the labor intensity is high, which leads to the waste of human resources. The cost of transporting the squeezed mud to the raw material department is high, and it is easy to cause environmental pollution during the transportation process. In addition, the efficiency of squeezing by the mud press is low, and even if more workers are employed, the mud in the pool cannot be squeezed out, and the clarity of the water quality during the squeezing process cannot be guaranteed. Therefore, in order to improve the above problems, the present application proposes the following embodiments.

[0036] like Figure 1 , Figure 2 As shown, this embodiment proposes an automatic separation system for ceramic edge grinding wastewater, which mainly includes: a sewage collection tank 100, a vertical flow high-level tank 300, a thick slurry tank 400 and a slurry extraction component 500. The sewage collection tank 100 is set underground, and specifically, a pit can be dug on the ground to form the sewage collection tank 100. The sewage collection tank 100 is used to collect sewage generated during the ceramic edge grinding process. The vertical flow high-level tank 300 is vertically set on the ground, so it has a relatively high height. The vertical flow high-level tank 300 is connected to the sewage collection tank 100 through the sewage pumping component 200. The vertical flow high-level tank 300 is used to precipitate the sewage transported by the sewage pumping component 200, so that the separated slurry is located at the bottom of the vertical flow high-level tank 300, and the separated clean water is located at the upper part of the vertical flow high-level tank 300. The thick stock pool 400 is arranged underground and below the vertical flow high-position tank 300, and is used to collect the mud discharged from the bottom of the vertical flow high-position tank 300; in a specific structure, the thick stock pool 400 can be dug out below the vertical flow high-position tank 300, and the settled mud is automatically discharged into the thick stock pool 400 below by gravity. The slurry extraction assembly 500 is connected to the thick stock pool 400, and is used to extract the mud in the thick stock pool 400 for reuse, for example, the mud can be extracted to the ball mill for reuse, so that the pressing process can be omitted.

[0037] In this embodiment, a ceramic grinding wastewater automatic separation system is provided, which realizes wastewater sedimentation through a vertical flow high-level tank 300, a sewage collection tank 100, and a concentrated slurry tank 400 arranged in a vertical direction. The sewage collection tank 100 collects sewage in the ceramic production process, and the concentrated sewage is pumped from underground to the vertical flow high-level tank 300 through a sewage pumping assembly 200. The vertical flow high-level tank 300 precipitates the sewage, and the separated mud is located at the bottom of the vertical flow high-level tank 300, and the separated clean water is located at the upper part of the vertical flow high-level tank 300. The clean water can be pumped out for reuse, and the mud is directly discharged downward through the bottom of the vertical flow high-level tank 300 and enters the concentrated slurry tank 400 below. The mud in the concentrated slurry tank 400 is pumped out for reuse through a slurry pumping assembly 500. Therefore, the vertical flow high-level tank 300 is used to replace multiple water tanks for sedimentation, which has the advantages of small footprint and space saving. Moreover, the vertical flow high-position tank 300 adopts a high-position vertical flow sedimentation method to precipitate the sewage in a relatively short time, quickly separate the granular objects, and improve the sewage treatment efficiency. The precipitated mud is discharged through the bottom of the vertical flow high-position tank 300 and can be automatically discharged to the thick slurry pool 400, thereby avoiding the safety hazards caused by open-air operation of personnel. The mud in the thick slurry pool 400 can be pumped to the ball mill workshop for reuse, reducing the squeezing process and realizing automatic operation. The mud is pumped by the slurry pumping component 500 so that the mud can be recycled, thereby replacing the squeezing process, avoiding the high cost of transporting the squeezed mud to the raw material department and the problem of easy environmental pollution during the transportation process. In addition, there will be no problems of low squeezing efficiency, many workers and inability to squeeze out the mud in the pool, and the problem of water clarity that cannot be guaranteed due to the pollution of clean water by the squeezed mud during the squeezing process is also avoided.

[0038] like Figure 2 As shown, further, the sewage collection pool 100 in this embodiment specifically includes an underground pool with a depth of 3.7 meters and a diameter of 5.5 meters. The sewage pumping assembly 200 is connected from the sewage collection pool 100 to the interior of the vertical flow type high-level tank 300 through the sewage input pipe 230 (8-inch galvanized steel pipe), so that the sewage pumping assembly 200 pumps the sewage to the vertical flow type high-level tank 300 through the steel pipe for sedimentation. A set of polyaluminum chloride coagulant dispenser and polyacrylamide dispenser are installed at the entrance of the sewage collection pool 100. The two dispensers can be a set of equipment. The equipment is an existing equipment and can be directly purchased. The specific structure description is not given. The automatic dosing of the two agents PAC (polyaluminum chloride coagulant) and PAM (polyacrylamide) can be realized, and the two agents can be added to the sewage in the sewage collection pool 100 after dilution with water, and the two dosages can be set according to the sewage circulation volume.

[0039] like Figure 1 , Figure 2As shown, further, the sewage pumping assembly 200 in this embodiment specifically includes: a sewage pump 210 and a sewage level gauge 220. The sewage pump 210 is connected to the sewage collection tank 100 and the vertical flow high-level tank 300 through the sewage input pipe 230. The sewage level gauge 220 is arranged in the sewage collection tank 100 and is electrically connected to the sewage pump 210. The sewage amount in the sewage collection tank 100 is detected by the sewage level gauge 220 to control the sewage pump 210. For example, the pumping speed, opening or closing of the sewage pump 210 can be controlled. In the specific structure, the sewage pump 210 can adopt multiple 37KW centrifugal water pumps, and the number of sewage pumps 210 is determined according to the number of vertical flow high-level tanks 300. The sewage level gauge 220 installed in the sewage collection tank 100 adopts an ultrasonic level gauge, which is a commonly used sensor, specifically used to detect the height of the water level. When it is detected that the water level in the sewage collection tank 100 is lower than the preset value, the sewage pump 210 is controlled to run at a low speed. When it is detected that the water level in the sewage collection tank 100 is higher than a preset value, the sewage pump 210 is controlled to run at a high speed to pump the sewage to the vertical flow high-level tank 300 for sedimentation.

[0040] like Figure 2 , Figure 3 , Figure 4 As shown, further, the vertical flow high-position tank 300 in this embodiment specifically includes: an outer bracket 310, a tank body 320 and a conical mud discharge pipe 330. The outer bracket 310 is used to be fixedly set on the ground, and the tank body 320 is vertically fixed on the outer bracket 310. The sewage transported by the sewage pumping assembly 200 overflows from the bottom of the tank body 320 and gradually settles. The conical mud discharge pipe 330 is vertically fixed at the bottom of the tank body 320, and the lower end of the conical mud discharge pipe 330 has a slurry outlet, which is connected to the thick slurry pool 400. The outer bracket 310 is used to stably support the entire vertical flow high-position tank 300. Through the vertical flow design of the tank body 320, the occupied area of ​​the ground is small. The occupied area of ​​the vertical flow high-position tank 300 in this embodiment is one-fifth of the occupied area of ​​the original pool structure. In addition, the vertical flow high-position tank 300 can treat sewage in a relatively short time, quickly separate granular objects, and improve the sewage treatment efficiency.

[0041] like Figure 2 , Figure 4As shown, further, a pneumatic butterfly valve 331 is installed at the slurry outlet in this embodiment, and the slurry outlet is opened or closed by pneumatically controlling the pneumatic butterfly valve 331. The pneumatic butterfly valve 331 installed at the slurry outlet realizes automatic slurry discharge. The pneumatic butterfly valve 331 is used to realize automatic control of slurry discharge. For example, the pneumatic butterfly valve 331 automatically controls the set time to automatically discharge the slurry into the thick slurry pool 400. It is usually set to automatically discharge the thick slurry for 8 seconds every 4 hours, that is, the pneumatic butterfly valve 331 automatically opens after a predetermined time, and then opens for another predetermined time and then the pneumatic valve automatically closes. In this way, there is no need for operators to operate the slurry discharge on the open-air pipeline, thereby eliminating the safety hazards caused by open-air operations.

[0042] like Figure 2 , Figure 4 As shown, further, in this embodiment, there are multiple conical mud discharge pipes 330, which are distributed at the bottom of the tank body 320, and the multiple conical mud discharge pipes 330 are connected to the thick slurry pool 400. In the specific structure, there are four conical mud discharge pipes 330 in this embodiment, which are distributed in a circular shape around the central axis of the tank body 320, which is conducive to rapid slurry discharge.

[0043] like Figure 2 , Figure 4 As shown, further, the tank body 320 in this embodiment specifically includes: an outer tank 321 and an inner cylinder 322. The outer tank 321 is fixedly arranged on the outer bracket 310, and the inner cylinder 322 is arranged in the outer tank 321, and is spaced a predetermined distance from the inner bottom surface of the outer tank 321. A sewage inlet cavity is formed on the inner side of the inner cylinder 322, and a clean water outlet cavity is formed between the inner cylinder 322 and the outer tank 321, and the sewage pumping assembly 200 is connected to the sewage inlet cavity. In the specific structure, the outer tank 321 and the inner cylinder 322 can be arranged concentrically. By specially designing the outer tank 321 and the inner cylinder 322 of the tank body 320 of the vertical flow high-level tank 300, the treated sewage reaches the quality purification standard, meets the production circulating water requirements, and realizes high-quality purification of sewage.

[0044] In this embodiment, the outer tank 321 is made of carbon steel Q235 steel plate, the conical mud discharge pipe 330 is made of 304 stainless steel, and the outer bracket 310 is made of ￠273*6 steel pipe (160*63*6mm, 100*48*4.9mm channel steel) as the main structure to stably support the entire outer tank 321. A clean water pipeline 610 (a pipeline with a diameter of 0.4 meters) is arranged on the top of the outer tank 321 to connect to the underground clean water pool 600. Among them, the height of the entire vertical flow high-level tank 300 is 12 meters, and the diameter of the outer tank 321 is 7 meters; the inner cylinder 322 inside the vertical flow high-level tank 300 is 6 meters high and 1.25 meters in diameter, and the inner cylinder 322 is made of 304 stainless steel plate; the upper end of the conical mud discharge pipe 330 has a diameter of 0.25-3.4m and a height of 5-5.2m. The bottom of the inner cylinder 322 is 0.5 meters away from the inner bottom surface of the outer tank 321. Through the setting of the vertical flow high-level tank 300, the sewage slowly flows from the bottom of the inner cylinder 322 to the outer tank 321. In this process, the particulate matter in the sewage is separated and precipitated, and the sewage slowly overflows from the bottom of the outer tank 321 and gradually precipitates. The separated clean water flows from the top of the outer tank 321 of the vertical flow high-level tank 300 along the clean water pipeline 610 into the clean water tank 600 on the ground, thereby meeting the sedimentation and separation requirements of the sewage.

[0045] like Figure 1 , Figure 4 As shown, further, the top of the inner cylinder 322 protrudes from the top of the outer tank 321. The top of the inner cylinder 322 is set higher than the top of the outer tank 321, so that the sewage in the inner cylinder 322 only reaches the height of the top of the outer tank 321, thereby preventing the sewage in the inner cylinder 322 from directly overflowing and discharging into the outer tank 321, so as to avoid excessive sewage from polluting the separated clean water.

[0046] like Figure 1 , Figure 2 As shown, further, in this embodiment, two vertical flow high-level tanks 300 are provided, and two sewage pumping assemblies 200 are correspondingly provided (it can be that two sewage pumps 210 are provided), and the two vertical flow high-level tanks 300 are connected to the sewage collection tank 100 through the two sewage pumping assemblies 200. The two vertical flow high-level tanks 300 can work at the same time, and the tops of the outer tanks 321 of the two vertical flow high-level tanks 300 are connected through pipes, and then pumped out to the clean water tank 600 below through a clean water pipe 610. The working state of the two vertical flow high-level tanks 300 can be adjusted and controlled according to the amount of sewage in the sewage collection tank 100. When the amount of sewage in the sewage collection tank 100 is large, the two sewage pumping assemblies 200 can be opened at the same time, so that the two vertical flow high-level tanks 300 work at the same time. Improve work efficiency and ensure that when the sewage treatment volume is relatively large, the sewage can still be stably precipitated and treated.

[0047] like Figure 1 , Figure 4As shown, further, the thick slurry pool 400 in this embodiment is arranged below the conical mud discharge pipe 330. The underground thick slurry pool 400 is used to collect the thick slurry settled in the vertical flow high-level tank 300. The underground thick slurry pool 400 includes a 3.7-meter-deep underground pool. The underground thick slurry pool 400 has a notch protruding from the ground, and the notch protrudes 0.8 meters above the ground. The conical mud discharge pipe 330 can directly discharge the settled mud into the thick slurry pool 400, which is convenient for the centralized reuse of the mud.

[0048] like Figure 2 , Figure 3 As shown, further, the slurry pumping assembly 500 specifically includes: a slurry pump 510 and a slurry pumping level 520. The slurry pump 510 is connected to the thick slurry pool 400 through a slurry pumping pipeline 530, and the slurry pumping level 520 is arranged in the thick slurry pool 400 and electrically connected to the slurry pump 510; the slurry pumping level 520 detects the amount of slurry in the thick slurry pool 400 to control the working state of the slurry pump 510, such as the speed of slurry pumping, opening or closing. The slurry pumping level 520 can be an ultrasonic level meter, and the slurry pump 510 can be a plunger pump, and the plunger pump is arranged on the ground. Through the setting of the slurry pumping level device 520 and the slurry pumping pump 510, the thick slurry pool 400 adopts an ultrasonic level device to control the height of the thick slurry, and the high and low positions of the thick slurry can be set, such as the low position of the thick slurry is set to 0.3 meters and the high position is set to 3 meters. When the slurry pumping level device 520 detects that the thick slurry is full to a height of 3 meters, the slurry pumping pump 510 automatically starts to pump slurry. When the slurry pumping level device 520 detects that the thick slurry is lower than 0.3 meters, the slurry pump 510 automatically stops. If the slurry pump 510 fails to start pumping slurry, the mud in the thick slurry pool 400 has reached a height of 3 meters, and the pneumatic butterfly valve 331 at the slurry outlet of the conical mud discharge pipe 330 will stop discharging slurry, effectively ensuring that the thick slurry will not flow out. The thick slurry is pumped to the ball mill workshop for reuse, and the pressing process is avoided. The use of this device can reduce the number of operators. Originally, four operators were needed. After adopting the vertical flow high-level tank 300 of this solution and automatic slurry discharge control, only one operator is needed, which effectively saves labor costs.

[0049] like Figure 1 , Figure 3 As shown, further, the clean water tank 600 in this embodiment is opened underground and connected to the upper part of the vertical flow type high-level tank 300 through the clean water pipeline 610 to collect the clean water precipitated and separated by the vertical flow type high-level tank 300. After the clean water is collected, it can be recycled and reused to save water resources.

[0050] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
