[0031] In the prior art, solid impurities and pollutants in sewage treatment equipment are directly treated as solid waste after separation, and no further treatment is performed on the solid impurities, which may cause environmental pollution.

[0032] The utility model provides a sewage treatment device.

[0033] See also Figure 1 to Figure 2 In one embodiment of the utility model, the sewage treatment device includes: a solid-liquid separation tank 100, a screen 200, a vibrating member 300 and a crushing box 400, wherein the solid-liquid separation tank 100 is formed with a cavity and an inlet 110 connected to the cavity is provided, the inlet 110 is arranged at the top of the solid-liquid separation tank 100 and is arranged near one side edge, and the sewage enters the cavity from the inlet 110. The screen 200 is arranged obliquely in the cavity, and the screen 200 includes a receiving end 210 and a discharging end 220, the receiving end 210 is arranged below the inlet 110, and the sewage falls into the receiving end 210 from the inlet 110, and the sewage includes solid impurities, and the level of the receiving end 210 is higher than the level of the discharging end 220, so that the solid impurities are transported from the receiving end 210 to the discharging end 220 under the action of their own gravity. The vibrating member 300 is fixedly connected to the outside of the solid-liquid separation tank 100, and the output shaft of the vibrating member 300 extends to the cavity and is connected to the screen 200 to drive the screen 200 to vibrate. The crushing box 400 is connected to the solid-liquid separation tank 100, and the solid impurities enter the crushing box 400 from the discharge end 220. The crushing box 400 is provided with a crushing mechanism 410, which is used to crush the solid impurities.

[0034] In the specific implementation process, the horizontal cross-section of the solid-liquid separation tank 100 can be square or circular or any other shape, which is not limited in the present embodiment, wherein the side profile of the screen 200 matches the inner wall of the cavity of the solid-liquid separation tank 100 to ensure that the sewage and the solid impurities in the sewage pass through the screen 200, and prevent the solid impurities from falling into the cavity below the screen 200. It should be noted that a number of filter holes are evenly arranged on the screen 200, and the size of the filter holes prevents solid impurities from passing through, thereby achieving the filtering effect. In addition, the screen 200 is preferably made of steel, so that the screen 200 has a certain strength, and solid impurities are prevented from damaging the screen 200 and requiring frequent replacement.

[0035] Sewage enters the chamber from the inlet 110, which is located at the top of the solid-liquid separation tank 100 and is arranged near the side. The inlet 110 is close to the side wall where the receiving end 210 of the screen 200 is installed, so that the sewage falls on the screen 200 and can be filtered through the screen 200 at the first time, so that the solid impurities stay on the screen 200. It can be understood that since the horizontal height of the receiving end 210 of the screen 200 is higher than the horizontal height of the discharge end 220, the screen 200 can filter the sewage to the greatest extent during the movement of the sewage along the screen 200 and the process of passing through the screen 200 and falling below the screen 200. And the horizontal height of the receiving end 210 is higher than the horizontal height of the discharge end 220, which can also make the solid impurities move along the inclined slope of the screen 200 to the discharge end 220 under the action of their own gravity and discharge the screen 200. The vibrating member 300 is a vibration motor, which is installed on the outer wall of the solid-liquid separation tank 100. The vibration motor is connected to a vibration rod, which passes through the side wall of the solid-liquid separation tank 100 and extends into the cavity. The vibration rod is connected to the screen 200, so that the vibration motor drives the screen 200 to vibrate. The vibration of the screen 200 can prevent solid impurities from adhering to the screen 200, so that the solid impurities can quickly move to the discharge end 220 to avoid affecting the filtration of sewage.

[0036] It can be understood that after being filtered by the screen 200, the sewage falls into the cavity below the screen 200 and is discharged for the next step of treatment. In this embodiment, the bottom wall of the cavity of the solid-liquid separation tank 100 is inclined, and a sewage outlet is provided on the side wall of the solid-liquid separation tank 100. The side of the bottom wall of the cavity close to the sewage outlet is the lowest point of the bottom, so that the sewage can be completely discharged along the inclined bottom wall. The solid impurities enter the crushing box 400, and the crushing mechanism 410 crushes the solid impurities. The solid impurities will be further processed after crushing to prevent the solid impurities from polluting the environment.

[0037] The technical solution of the utility model separates solid impurities from sewage liquid by setting a screen 200 in the solid-liquid separation tank 100. The screen 200 is set at an angle so that the solid impurities move along the screen 200 into the crushing box. The crushing mechanism 410 in the crushing box 400 further crushes the solid impurities so that the solid impurities are processed, thereby avoiding environmental pollution. The sewage treatment device provided by the technical solution of the utility model has a simple structure and control, strong practicality, and can process solid impurities in sewage.

[0038] In one embodiment, the crushing mechanism 410 includes a crushing motor 411, a rotating shaft 412 and a crushing blade 413. The rotating shaft 412 is rotatably connected to the crushing box 400. The crushing blade 413 is arranged on the outer periphery of the rotating shaft 412 and spirally extends along the axis of the rotating shaft 412. The crushing motor 411 is drivingly connected to the rotating shaft 412.

[0039] The crushing motor 411 is installed on the outer wall of the crushing box 400. The crushing motor 411 drives the rotating shaft 412 to rotate, so that the crushing blades 413 on the rotating shaft 412 are crushed when they contact the solid impurities under the rapid rotation of the rotating shaft 412. It can be understood that in order to ensure the crushing effect of the solid impurities, the rotating shaft 412 spans the crushing box 400 to avoid missing the solid impurities that have not been crushed.

[0040] In order to further improve the crushing efficiency and crushing effect, in this embodiment, the crushing box 400 is provided with two groups of crushing mechanisms 410, and the two groups of rotating shafts 412 are arranged in parallel and located in the same horizontal plane. The two groups of crushing mechanisms 410 are arranged in parallel and located in the same horizontal plane, and the two groups of crushing blades 413 cooperate with each other or stay away from each other to avoid interference. In this embodiment, under the premise of ensuring the crushing effect, the two groups of crushing blades 413 are spaced a certain distance apart in the horizontal direction. It can be understood that the rotation speed of the two groups of crushing mechanisms 410 is consistent, and the start and stop are controlled synchronously.

[0041] In one embodiment, the crushing box 400 is provided with a feed port 420, and the feed port 420 is provided with a first guide plate 430, and one end of the first guide plate 430 away from the feed port 420 extends toward the center direction of the crushing box 400, and solid impurities fall into the first guide plate 430 from the feed port 420. In this embodiment, the crushing box 400 cooperates with the solid-liquid separation tank 100. In order to reasonably set and reduce costs, in the specific implementation process, the feed port 420 is close to the side wall of the crushing box 400, and is further close to the solid-liquid separation tank 100. In this way, when the solid impurities enter the crushing box 400 through the feed port 420, they are concentrated on one side of the crushing box 400, and then they will fall into one end of the crushing mechanism 410, thereby affecting the crushing effect. In this embodiment, by setting the first guide plate 430, the solid impurities are dispersed and fall into the crushing mechanism 410 under the action of the first guide plate 430, avoiding the concentration of solid impurities, thereby ensuring the crushing effect.

[0042] Furthermore, the crushing box 400 includes a material guide bin, a crushing bin and a spray bin which are interconnected. The first guide plate 430 is arranged in the material guide bin, the crushing mechanism 410 is arranged in the crushing bin, and the two opposite side walls of the crushing bin are inclined to form a second guide plate 440. A spray pipe 450 is arranged in the spray bin, and the spray pipe 450 sprays a neutralizing solvent.

[0043] In the specific implementation process, the crushing box 400 is composed of a guide bin, a crushing bin, and a spray bin from top to bottom, and the three are connected in sequence. Among them, one end of the first guide plate 430 is arranged near the feed port 420 and fixedly installed on the side wall of the guide bin, and the other end extends to the other side and tilts toward the crushing bin, so that solid impurities are dispersed and fall into the crushing bin. The crushing mechanism 410 is installed in the crushing bin, and the rotating shaft 412 of the crushing mechanism 410 is arranged across the crushing bin, so that the crushing blade 413 can crush the solid impurities falling into various positions of the crushing bin to ensure the crushing effect. In addition, the side wall of the crushing bin is inclined to form a second guide plate 440. Specifically, the bottom ends of the second guide plates 440 are inclined in the direction of approaching each other. On the one hand, the second guide plate guides the solid impurities falling into the crushing bin, so that the solid impurities fall onto the crushing mechanism 410 as much as possible. On the other hand, the second guide plate 440 also guides the crushed solid impurities, so that they fall into the spray bin in a concentrated manner. On the one hand, the inclined second guide plate can also prevent the crushed solid impurities from adhering to the second guide plate and affecting the discharge.

[0044] It is understandable that the surface of solid impurities will carry sewage, which contains harmful substances. By spraying neutralizing agents, the sewage carried by solid impurities can be eliminated to avoid pollution to the environment and to avoid affecting the further utilization of solid impurities. Among them, the neutralizing agent is selected according to the harmful substances in the sewage.

[0045] In one embodiment, the sewage treatment device also includes a conveying mechanism 500, which is provided with an inlet 510 and an outlet 520. The inlet 510 is arranged close to the discharge end 220, and the outlet 520 is connected to the crushing box 400. Solid impurities fall into the conveying mechanism 500 through the inlet 510 from the discharge end 220, and fall into the crushing box 400 through the outlet 520.

[0046] The solid impurities are transported to the crushing box 400 through the conveying mechanism 500. Specifically, the conveying mechanism 500 includes a conveying motor 540, a conveying pipe 550 and a screw conveying shaft 560. The conveying motor 540 is fixed to the crushing box 400, and the conveying motor 540 is drivingly connected to the screw conveying shaft 560. The screw conveying shaft 560 is rotatably arranged in the conveying pipe 550. The discharge port 520 and the feed port 510 are arranged at opposite ends of the conveying pipe 550 in the axial direction. The conveying pipe 550 is inclined. The horizontal height of the end of the conveying pipe 550 away from the screen 200 is higher than that of the end of the conveying pipe 550 close to the screen 200. A water outlet 530 is provided at the bottom of the side wall of the conveying pipe 550 close to the screen 200.

[0047] In this embodiment, the conveying mechanism 500 is a screw conveying device. Specifically, the conveying motor 540 drives the screw conveying shaft 560 to rotate in the conveying pipe 550 to convey solid impurities. The conveying pipe 550 is provided with an inlet 510 and an outlet 520. Specifically, the inlet 510 is provided on the top surface of the side wall of the conveying pipe 550 and is located below the discharge end 220 to receive the solid impurities discharged by the screen 200. The outlet 520 is provided at the bottom of the side wall of the conveying pipe 550 and is located above the feed inlet 420 of the crushing box 400 so that the solid impurities fall directly into the feed inlet 420.

[0048] In addition, it is understandable that solid impurities will be mixed with sewage liquid, and the spiral conveying shaft 560 is tilted, which can make the water mixed with the solid impurities flow to the bottom along the inner wall of the conveying pipe 550 during the process of conveying solid impurities. In this embodiment, the bottom of the conveying pipe 550 is provided with a water outlet 530, so that the sewage liquid falls into the solid-liquid separation box through the water outlet 530.

[0049] It can be understood that since the spiral conveying shaft 560 is set at an angle, in order to ensure the stability of the conveying motor 540, the output shaft of the conveying motor 540 is set horizontally. Therefore, in this embodiment, the conveying mechanism 500 also includes a coupling 570, and the conveying motor 540 is connected to the conveying shaft through the coupling 570, thereby ensuring that the conveying motor 540 smoothly drives the bolt conveying shaft to rotate.

[0050] In one embodiment, a third guide plate 120 is further provided in the solid-liquid separation tank 100 , one end of the third guide plate 120 is hinged to the inner wall of the cavity, and the other end is connected to the screen 200 and is disposed close to the discharge end 220 .

[0051] The third guide plate 120 is tiltedly arranged in the solid-liquid separation tank 100, and the third guide plate 120 and the screen 200 form a funnel-shaped structure, so that the solid impurities on the screen 200 can be concentrated and fall into the conveying pipe 550. It can be understood that the feed port 510 of the conveying pipe 550 is located below the funnel-shaped structure to facilitate the reception of solid impurities.

[0052] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
