Description

Technical Field

[0001] This utility model specifically relates to the field of wastewater treatment technology, and more specifically to a new type of wastewater slag removal equipment. Background Technology

[0002] Wastewater sludge removal is a key pretreatment step in the wastewater treatment process. It mainly removes suspended solids, particulate matter, fibrous impurities and other sludge from wastewater through physical, mechanical or chemical methods to reduce the load on subsequent treatment, protect equipment and improve overall treatment efficiency. It also removes large particulate impurities (such as branches, plastics, metal fragments, etc.) from wastewater to prevent pipe blockage.

[0003] However, in practice, it has been noted that current sludge removal equipment generally adds flocculants to wastewater, and then allows large particles of impurities to settle to the bottom of the sedimentation tank after sedimentation. When the residue in the sedimentation tank accumulates to a certain extent, mechanical devices are needed to scrape the sediment at the bottom of the tank to the sludge collection hopper or sludge discharge port. During this process, the internal sewage needs to be emptied, otherwise the wastewater will be cleaned up along with the sewage. Moreover, the whole process consumes a lot of time, manpower and resources, resulting in high sludge removal costs. Utility Model Content

[0004] The purpose of this invention is to provide a novel wastewater sludge removal device. This device utilizes an inclined bottom design of the wastewater sedimentation tank in conjunction with a semi-circular sedimentation trough to settle residues in the wastewater. An inclined partition plate further separates the wastewater from the residues. Finally, a sludge cleaner and a hollow lifting pipe work together to remove the remaining residues. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel wastewater sludge removal device includes a sewage sedimentation tank with a conical bottom, a semi-circular sedimentation trough integrally provided at the bottom of the sewage sedimentation tank, and a hollow lifting pipe corresponding to the semi-circular sedimentation trough fixedly connected to the end of the sewage sedimentation tank.

[0007] A slag cleaner is installed on the inside of the hollow lifting pipe. The slag cleaner includes a collecting shaft placed in a semi-circular settling tank and an inclined shaft placed in the hollow lifting pipe. A universal coupling is used for transmission between the collecting shaft and the inclined shaft.

[0008] As a further technical solution of this utility model, auger blades are fixedly connected to the outer sides of the collecting shaft and the inclined shaft, and each auger blade is provided with separation holes in a ring array.

[0009] As a further technical solution of this utility model, a drive motor is fixedly connected to the end of the sewage sedimentation tank away from the hollow lifting pipe, and the end of the drive motor passes through the sewage sedimentation tank and is in transmission cooperation with the end of the collection shaft away from the inclined shaft.

[0010] As a further technical solution of this utility model, the sewage sedimentation tank is also fixedly connected with an inclined partition plate, and the inclined partition plate is provided with separation holes in a rectangular array, and the inclined partition plate is located above the collection shaft.

[0011] As a further technical solution of this utility model, the bottom of the inclined partition plate is inclined toward the side close to the hollow lifting tube, and the end of the inclined partition plate is attached to the end of the hollow lifting tube.

[0012] As a further technical solution of this utility model, a box support is fixedly connected to the bottom of the sewage sedimentation tank, and a discharge hopper is integrally provided at the end of the hollow lifting material pipe away from the collection shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the inclined setting at the bottom of the sewage sedimentation tank, allows the residue in the wastewater to settle into the semi-circular sedimentation tank at the bottom. Furthermore, the inclined partition plate set in the sewage sedimentation tank can separate the sewage and the residue, without affecting the normal absorption of sewage during the treatment process, and can also prevent the residue from moving with the water flow, thereby improving the separation effect.

[0015] 2. In this utility model, the drive motor drives the collecting shaft to rotate, and the auger blades on the collecting shaft cooperate with the semi-circular sedimentation tank at the bottom to push the sedimented residue forward to the end of the inclined shaft. Then, when the auger blades on the inclined shaft rotate, they cooperate with the hollow lifting pipe to move the residue at the bottom to the discharge hopper above for removal.

[0016] 3. In this utility model, the auger blades on the collecting shaft and the auger blades on the inclined shaft are provided with separation holes in a ring array. When the auger blades rotate, the sewage can pass through the inside of the separation holes, thereby reducing the resistance to cleaning the residue and ensuring the cleaning effect of the residue.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a novel wastewater slag removal device, including a sewage sedimentation tank 1 with a conical bottom, a semi-circular sedimentation trough 6 integrally provided at the bottom of the sewage sedimentation tank 1, and a hollow lifting pipe 3 corresponding to the semi-circular sedimentation trough 6 is fixedly connected to the end of the sewage sedimentation tank 1.

[0027] A slag cleaner 7 is installed on the inner side of the hollow lifting pipe 3. The slag cleaner 7 includes a collection shaft 71 placed in a semi-circular sedimentation tank 6 and an inclined shaft 74 placed in the hollow lifting pipe 3. A universal coupling 75 is used for transmission between the collection shaft 71 and the inclined shaft 74.

[0028] By adopting the above technical solution, the wastewater residue is allowed to settle in the semi-circular sedimentation tank 6 at the bottom of the wastewater sedimentation tank 1 by the inclined setting below it. The inclined partition plate 2 set in the wastewater sedimentation tank 1 can separate the wastewater and the residue, without affecting the normal absorption of wastewater during the treatment process. It can also prevent the residue from moving with the water flow and improve the separation effect.

[0029] Furthermore, auger blades 72 are fixedly connected to the outer sides of the collecting shaft 71 and the inclined shaft 74, and each auger blade 72 is provided with separation holes 73 in a ring array.

[0030] Furthermore, a drive motor 4 is fixedly connected to the end of the sewage sedimentation tank 1 away from the hollow lifting pipe 3, and the end of the drive motor 4 passes through the sewage sedimentation tank 1 and is engaged with the end of the collection shaft 71 away from the inclined shaft 74.

[0031] By adopting the above technical solution, the drive motor 4 drives the collecting shaft 71 to rotate, and the auger blades 72 set on the collecting shaft 71 cooperate with the semi-circular sedimentation tank 6 set at the bottom to push the sedimented residue forward to the end of the inclined shaft 74. Then, when the auger blades 72 set on the inclined shaft 74 rotate, they cooperate with the hollow lifting pipe 3 to move the residue at the bottom to the discharge hopper 8 above for removal.

[0032] More specifically, the sewage sedimentation tank 1 is also fixedly connected with an inclined partition plate 2, and the inclined partition plate 2 has separation holes in a rectangular array, and the inclined partition plate 2 is located above the collection shaft 71.

[0033] Furthermore, the bottom of the inclined partition plate 2 is inclined toward the side close to the hollow lifting pipe 3, and the end of the inclined partition plate 2 is attached to the end of the hollow lifting pipe 3.

[0034] Furthermore, a box support 5 is fixedly connected to the bottom of the sewage sedimentation tank 1, and a discharge hopper 8 is integrally provided at the end of the hollow lifting material pipe 3 away from the collection shaft 71.

[0035] Furthermore, the auger blades 72 on the collecting shaft 71 cooperate with the semi-circular sedimentation tank 6. When the collecting shaft 71 drives the auger blades 72 to rotate, it pushes the residue towards the end of the hollow lifting pipe 3 to collect the residue.

[0036] By adopting the above technical solution, the auger blades 72 on the collecting shaft 71 and the auger blades 72 on the inclined shaft 74 are both provided with separation holes 73 in a ring array. When the auger blades 72 rotate, the sewage can pass through the inside of the separation holes 73, thereby reducing the resistance to cleaning the residue and ensuring the cleaning effect of the residue.

[0037] Furthermore, the auger blades 72 on the inclined shaft 74 are movably connected to the inner side of the hollow lifting pipe 3. When the collecting shaft 7 rotates, it drives the inclined shaft 74 to rotate through the universal coupling 75. The auger blades 72 on the inclined shaft 74 can lift the residue at the end of the hollow lifting pipe 3 upward for removal.

[0038] The working principle of this utility model is as follows: During use, sewage is first introduced from the left side of the sewage sedimentation tank 1 using a sewage pump. After entering the inner side of the sewage sedimentation tank 1, the internal residue will settle downwards due to its own gravity, accumulating in the semi-circular sedimentation trough 6 at the bottom of the sewage sedimentation tank 1. Furthermore, the inclined partition plate 2, which is set at an angle, can both ensure the normal flow of sewage and block the residue, thus concentrating it at the bottom. During cleaning, the drive motor 4 drives the collecting shaft 71 to rotate, and the collecting shaft 71 is connected to the universal coupling 75 at its end... The inclined shaft 74 rotates synchronously, and the auger blades 72 on the collecting shaft 71 cooperate with the semi-circular sedimentation tank 6 to push the residue deposited in the semi-circular sedimentation tank 6 towards the end of the hollow lifting pipe 3. Meanwhile, the auger blades 72 on the inclined shaft 74 cooperate with the hollow lifting pipe 3 to move the residue to the other end, and finally discharge it from the discharge hopper 8. Furthermore, the separation holes 73 opened on the auger blades 72 can ensure that only the residue is cleaned without affecting the storage of sewage inside the sewage sedimentation tank 1. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
