Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of sewage treatment, and in particular to a sludge collecting hopper and a sedimentation tank. Background Art
[0002] Sewage treatment usually includes processes such as sedimentation, filtration, and flotation to separate solids from water in sewage. For the sedimentation process, related technologies include using integrated sedimentation modules to improve sewage treatment efficiency. In the sedimentation process of sewage treatment, a sedimentation module is required to initially separate water from sludge. A sludge collecting hopper is provided below the sedimentation module, and the sludge precipitated in the sedimentation module is collected by the sludge collecting hopper for subsequent treatment. Due to the water quality characteristics of sewage and the long-term operation of the equipment will cause sludge to adhere to the inner wall of the sludge collecting hopper, during the operation of the equipment, the sludge concentration near the bottom of the sludge collecting hopper will be lower than that in the middle of the sludge collecting hopper, which ultimately leads to unsatisfactory sludge precipitation in the sludge collecting hopper. Utility Model Content
[0003] The purpose of the present disclosure is to provide a mud collecting hopper and a sedimentation tank to solve the problem of poor sedimentation effect caused by too low concentration in the lower part of the mud collecting hopper in the related art.
[0004] In order to achieve the above object, the present disclosure provides a mud collecting bucket, comprising:
[0005] A holding chamber, used for holding sludge;
[0006] A power member, arranged outside the accommodating cavity;
[0007] a plurality of blades, arranged at the lower part of the inner side of the accommodating cavity, wherein the output end of the power member passes through the accommodating cavity to drive the blades to rotate; and
[0008] The mud discharge pipeline is connected to the accommodating chamber.
[0009] Optionally, the mud collecting bucket comprises:
[0010] A first mud collecting section, wherein the first mud collecting section is a hollow multi-prism structure surrounded by multiple side walls and is used to connect to the sedimentation module; and
[0011] The second mud collecting section is connected below the first mud collecting section, and the mud discharge pipeline is connected to the second mud collecting section.
[0012] Optionally, the second mud collection stage includes:
[0013] A connecting tube connected to the first mud collecting section; and
[0014] The sedimentation hopper is an inverted cone structure and is connected below the connecting tube.
[0015] Optionally, the output end of the power member is connected to the tip of the inverted cone structure, and the shape of the blade matches the inverted cone structure to scrape sludge along the inner wall of the inverted cone structure during rotation.
[0016] Optionally, a joint is connected between the mud discharge pipeline and the second mud collecting section, and the joint is connected to the side wall of the inverted cone structure.
[0017] Optionally, the connector comprises:
[0018] a mud inlet connected to the inverted cone structure; and
[0019] A mud outlet is connected to the mud discharge pipeline, the diameter of the mud outlet is smaller than the diameter of the mud inlet, and the mud outlet is eccentrically arranged on a side of the center of the mud inlet away from the power component.
[0020] Optionally, the blades are arranged obliquely in a height direction of the mud collecting bucket.
[0021] Optionally, a plurality of water holes are arranged at intervals on the blade.
[0022] Optionally, a sealing sleeve is connected between the power member and the accommodating cavity.
[0023] According to yet another aspect of the present disclosure, a sedimentation tank includes a sedimentation module and the above-mentioned mud collecting bucket.
[0024] According to the above technical solution, during the sedimentation process, the sludge concentration near the bottom of the sludge collecting bucket will be lower than that in the middle of the sludge collecting bucket, which will eventually lead to unsatisfactory sludge sedimentation in the sludge collecting bucket. Therefore, the blades are arranged at the lower part of the sludge collecting bucket to fully stir the lower part of the sludge collecting bucket. The stirring of the lower part can accelerate the sedimentation of the upper sludge and the mixing of the lower part through the vortex brought by the stirring, thereby improving the sedimentation effect of the sludge.
[0025] Other features and advantages of the present disclosure will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0032] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" are defined for the overall arrangement of the mud bucket, and "inner" and "outer" are defined for the outline of the corresponding components. The use of terms such as "first" and "second" is intended to distinguish different components and does not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.
[0033] According to one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, a mud collecting bucket is provided, comprising a receiving chamber, a power member 3, a plurality of blades 4 and a mud discharge pipeline 5. The receiving chamber is used to receive mud, and the power member 3 can be arranged outside the receiving chamber. The plurality of blades 4 can be arranged at the lower part of the inner side of the receiving chamber, and the output end of the power member 3 passes through the receiving chamber and is connected to the blades 4 to drive the blades 4 to rotate. The mud discharge pipeline 5 can be connected to the receiving chamber to discharge the mud in the receiving chamber.
[0034] According to the above technical solution, during the sedimentation process, the sludge concentration near the bottom of the sludge collecting bucket will be lower than that in the middle of the sludge collecting bucket, which will eventually lead to unsatisfactory sludge sedimentation in the sludge collecting bucket. Therefore, the blade 4 is arranged at the lower part of the sludge collecting bucket to fully stir the lower part of the sludge collecting bucket. The stirring of the lower part can accelerate the sedimentation of the upper sludge and the mixing of the lower part through the vortex brought by the stirring, thereby improving the sedimentation effect of the sludge.
[0035] It should be noted that the power member 3 may be a servo motor, and its rotation speed may be adjusted according to the stirring requirements, which is not limited in the present disclosure. A sealing sleeve may be connected between the power member 3 and the accommodating chamber to prevent water in the mud collecting bucket from leaking from the position between the power member 3 and the accommodating chamber. The sealing sleeve may be made of rubber or other expansion materials, which is not limited in the present disclosure.
[0036] Furthermore, if Figure 1 and Figure 2As shown, the mud collecting bucket may include a first mud collecting section 1 and a second mud collecting section 2. The first mud collecting section 1 may be a hollow polyhedral structure formed by multi-sided side walls for connection with the sedimentation module, the second mud collecting section 2 is connected to the bottom of the first mud collecting section 1, the second mud collecting section 2 and the first mud collecting section 1 may form a accommodating chamber, the mud discharge pipeline 5 is connected to the second mud collecting section 2, and the mud discharge pipeline 5 is located in the second mud collecting section 2 and is located at the bottom of the mud collecting bucket, which is convenient for the discharge of the settled sludge. Here, the first mud collecting section 1 and the second mud collecting section 2 may be welded on site using iron sheets, and the first mud collecting section 1 is set to a polyhedral structure in order to enable the mud collecting bucket to be better spliced with the sedimentation module, so as to facilitate the modularization of the entire sedimentation tank. During the installation of the sedimentation tank, due to the structural complexity of the sedimentation module, the sedimentation module needs to be assembled first. The sedimentation module is a fixed shape structure, and is generally a cuboid or a cube, while the mud collecting bucket can be welded on site using iron sheets according to the required shape. In the case where the shape of the sedimentation module is fixed, if the mud collecting bucket is only a cylindrical or conical structure, it is not convenient for the annular iron sheet to be directly welded with the sedimentation module with a rectangular contact surface. Therefore, the mud collecting bucket is at least divided into the first mud collecting section 1 and the second mud collecting section 2 to ensure that the shape of the first mud collecting section 1 matches the shape of the sedimentation module, so that the first mud collecting section 1 is first welded under the sedimentation module, thereby improving the sealing of the connection between the two. Compared with the welding between the iron sheet and the fixed frame, the structure surrounded by the iron sheet itself is not fixed in shape and has a certain ductility. Therefore, when the first mud collecting section 1 and the second mud collecting section 2 are welded, the iron sheet at the connection between the two after welding can automatically adjust in shape. Therefore, there is no need to match the shape of the iron sheet and the fixed frame between the first mud collecting section 1 and the sedimentation module before welding. The welding of the two can be completed only by the edges of the first mud collecting section 1 and the second mud collecting section 2 in contact.
[0037] Furthermore, if Figure 1 As shown, the second mud collecting section 2 may include a connecting tube 21 and a settling hopper 22, the connecting tube 21 is connected to the first mud collecting section 1, and the settling hopper 22 may be an inverted cone structure, and is connected below the connecting tube 21. The settling hopper 22 is an inverted cone, which can facilitate the sedimentation and aggregation of sludge, and the connecting tube 21 can provide a buffering effect for the connection between the prismatic and circular shapes between the settling hopper 22 and the first mud collecting section 1, thereby improving the connection sealing of the mud collecting hopper and reducing the possibility of leakage at the connection.
[0038] Furthermore, if Figure 1 and Figure 2As shown, the output end of the power member 3 can be connected to the tip of the inverted cone structure, and the shape of the blade 4 matches the inverted cone structure so as to scrape away the sludge along the inner wall of the inverted cone structure when rotating. The lower edge of the blade 4 can be in contact with the inner wall of the inverted cone structure, or a certain gap can be left, which is not limited in the present disclosure. In order to reduce the damage caused by the contact between the blade 4 and the inner wall of the sedimentation bucket 22 to the sedimentation bucket 22 or the blade 4 and the power member 3 connected to the blade 4, when the scraping effect is achieved, the blade 4 can be made of a flexible material to prevent hard contact between the blade 4 and the sedimentation bucket 22, and can also reduce the friction resistance of the blade 4 during the stirring process, reduce the power of the power member 3, and play a role in protecting the power member 3.
[0039] For the setting of blade 4, Figure 1 and Figure 2 As shown, the blade 4 can be tilted in the height direction of the mud collecting bucket. During the rotation of the blade 4, the blade 4 has a tendency to push the sludge to the bottom of the mud collecting bucket, so that the sludge can be better gathered at the bottom to improve the sedimentation effect of the sludge. In addition, a plurality of water holes 41 can be arranged at intervals on the blade 4. The water holes 41 can effectively reduce the resistance encountered by the blade 4 during the stirring process and improve the stirring effect on the sewage flow in the mud collecting bucket. The water holes 41 can be distributed only at intervals in the upper half or lower half of the blade 4, or can be distributed at intervals on the entire blade 4, can be regularly distributed at equal intervals, or can be distributed randomly, and the present disclosure does not limit this.
[0040] According to one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, a joint 6 can be connected between the mud discharge pipeline 5 and the second mud collection section 2, and the joint 6 is connected to the side wall of the inverted cone structure. The joint 6 can be a concentric joint or a special-shaped joint, and the specific structure is shown below.
[0041] Furthermore, if Figure 1 and Figure 2 As shown, the joint 6 may include a mud inlet 61 and a mud outlet 62, the mud inlet 61 is connected to the inverted cone structure, the mud outlet 62 is connected to the mud discharge pipeline 5, and the diameter of the mud outlet 62 is smaller than the diameter of the mud inlet 61. The mud outlet 62 is eccentrically arranged at a side of the center of the mud inlet 61 away from the power part 3, that is, Figure 1 and Figure 2Taking the drawing direction as an example, the power member 3 is arranged at the center of the sedimentation bucket 22, the mud inlet 61 is eccentrically arranged relative to the sedimentation bucket 22, and is arranged on the right side of the power member 3, and the mud outlet 62 is arranged on the right side of the center of the mud inlet 61, so that the mud outlet 62 is both eccentrically arranged compared to the mud inlet 61 and far away from the power member 3 compared to the center of the mud inlet 61. The axis of the output end of the power member 3, the center of the mud inlet 61, and the center of the mud outlet 62 can be three points collinear, or the axis of the output end of the power member 3 and the connecting line of the center of the mud inlet 61, and the connecting line of the center of the mud inlet 61 and the center of the mud outlet 62 are at an angle to each other, and the present disclosure does not limit this. In this way, the center of the mud outlet 62 is farther from the power member 3 than the center of the mud inlet 61, and the mud discharge pipeline 5 connected to the mud outlet 62 will also be farther away from the power member 3, so that the power member 3 and the mud discharge pipeline 5 can be fully spaced apart to prevent leakage or damage caused by mutual interference between the power member 3 and the mud discharge pipeline 5.
[0042] On the basis of the above scheme, the present disclosure further provides a sedimentation tank, which includes a sedimentation module and the above-mentioned mud collecting bucket, and the sedimentation tank has all the beneficial effects of the above-mentioned mud collecting bucket, which will not be repeated here.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0045] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
