Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment, and in particular to a sewage treatment impurity collection device. Background Technology

[0002] With the development of the times, the problem of water pollution has become increasingly serious, which makes it necessary for us to make further improvements in sewage treatment. The sewage treatment process is mainly divided into the primary filtration of large-volume impurities, including plastics, paper scraps, feces, etc. These large-volume impurities will undergo primary filtration after entering the pipes, which mainly filters out these large-volume impurities. Subsequently, some small particulate matter will pollute the garbage and need to undergo secondary filtration.

[0003] When using filter plates to filter large impurities, clogging is very likely to occur, causing the entire process to stall, hindering work and greatly affecting efficiency. Furthermore, since there is no centralized disposal area for these large impurities after processing, they can cause secondary contamination. Therefore, we need to collect these large impurities to achieve faster secondary processing. During this process, we also need to ensure that these large impurities do not cause clogging and affect our work efficiency. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example 1

[0030] Reference Figure 1-7 The first embodiment of this utility model provides a wastewater treatment impurity collection device, which includes a box body 100, which includes a cover plate 101 and a bottom plate 102 respectively disposed at the upper and lower ends, a bracket 103 disposed at the bottom of the bottom plate 102, a limiting groove 104 cooperating with the cover plate 101, and a locking component 105. A filter assembly 200 is disposed and connected to the cover plate 101, which includes several sets of connecting rods 201, a rotating disk 202 and a screen hopper 203 respectively fixedly connected to the two ends of the connecting rods 201, and a vortex component 204 fixedly connected to the side wall between the connecting rods 201.

[0031] Furthermore, the cylinder 300, which is disposed between the housing 100 and the filter assembly 200, includes several sets of through holes 301 opened on the circumferential sidewall and a locking disc 302 at the bottom that cooperates with the locking component 105 for locking. The cover plate 101 has a water inlet hole 101a opened in the center. A limiting block 101b is provided at the bottom of the cover plate 101. The limiting block 101b cooperates with the limiting groove 104 for limiting. A rotating slot 101c is opened at the center of the bottom of the cover plate 101. The internal cross-section of the rotating slot 101c is larger than the external cross-section. The rotating slot 101c is divided into two grooves. The inner groove allows the rotating disc 202 to rotate in the groove, while the bottom groove restricts the rotating disc 202 in the vertical direction to prevent the rotating disc 202 from disengaging from the rotating slot 101c.

[0032] Furthermore, the locking component 105 includes a locking groove 105a formed on the annular surface of the housing 100 and a fixed shell 105b. A pull rod 105c is provided through the fixed shell 105b and slides inside the fixed shell 105b. A telescopic spring 105b-1 is fixedly provided at the bottom inside the fixed shell 105b. One end of the pull rod 105c is provided with a locking block 105c-1 that cooperates with the locking disc 302, and the other end is provided with a locking plate 105c-2. The locking plate 105c-2 cannot pass through the fixed shell 105b. The contact surface of the locking block 105c-1 with the locking disc 302 is inclined downwards, and the other end of the telescopic spring 105b-1 abuts against the locking block 105c-1.

[0033] Specifically, the fixing shell 105b outside the locking groove 105a is hollow, and a through groove is opened at the end of the fixing shell 105b away from the locking groove 105a, so that the pull rod 105c can slide through the through groove in the fixing shell 105b. The locking block 105c-1 on the pull rod 105c can cooperate with the fixing groove 302a on the locking plate 302. The locking block 105c-1 itself is inserted into the box 100 when no external force is applied. When the cylinder 300 is placed into the box 100, the locking plate 302 at the bottom of the cylinder 300 will contact the inclined end of the locking block 105c-1. The locking disc 302 presses against the inclined end of the locking block 105c-1, causing the locking block 105c-1 to compress the telescopic spring 105b-1 and retract into the fixed shell 105b. At this time, the locking disc 302 needs to be rotated so that the fixing groove 302a on the locking disc 302 is aligned with the locking block 105c-1. At the moment of alignment, the telescopic spring 105b-1 will release its elastic force to reset the locking block 105c-1 into the fixing groove 302a. At this time, the locking block 105c-1 restricts the movement of the cylinder 300 to form a lock. Afterwards, by aligning the limiting block 101b on the cover plate 101 with the limiting groove 104 and inserting it, the installation can be completed.

[0034] Furthermore, during the disassembly and cleaning process, the staff only needs to pull the card plate 105c-2 to make the card block 105c-1 overcome the elastic force of the telescopic spring 105b-1 and disengage from the fixing groove 302a. At this time, it is also necessary to rotate the cylinder 300 and pull out the cylinder 300 to complete the disassembly. Example 2

[0035] Reference Figure 1-7This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a flange 202a on the circumferential surface of the rotating disk 202. The flange 202a is limited to rotating within the limiting groove 104. The surface of the sieve hopper 203 has several sets of filter holes 203a. The number of filter holes 203a can be determined according to the situation. Waste that cannot be filtered out by the filter holes 203a will slide down along the inclined direction of the rotating disk 202. The top of the vortex element 204 cooperates with the water inlet hole 101a. The bucket 203 is conical and its outer ring extends downward to the edge of the through hole 301. The vortex element 204 has a spiral water channel 204a inside. The side wall of the vortex element 204 is fixedly set with the side wall of all the connecting rods 201. Several sets of connecting rods 201 surround the vortex element 204 and fit against the side wall of the vortex element 204. It should be noted that the distance between the connecting rods 201 must not be less than the cross-section of the through hole 301. The end point of the water channel 204a is matched with the upper surface of the sieve bucket 203.

[0036] Furthermore, the diameter of the through hole 301 is larger than that of the filter hole 203a. The side wall of the locking disc 302 is provided with a fixing groove 302a, which is connected to the locking groove 105a. The card block 105c-1 passes through the locking groove 105a and is limited in the fixing groove 302a.

[0037] Furthermore, the bottom of the housing 100 extends into the interior of the cylinder 300 and has a drainage hole 303, with the bottom surface of the cylinder 300 extending downwards at an angle to the drainage hole 303.

[0038] Specifically, when the water flows through the inlet hole 101a to the vortex element 204 and then through the water guide trough 204a to the screen hopper 203, the water flows along the screen hopper 203 to the through hole 301. During this distance, the water first flows through the filter hole 203a into the cylinder 300. Large impurities cannot pass through the filter hole 203a and are discharged through the through hole 301 to the position between the cylinder 300 and the box 100. The area between the cylinder 300 and the box 100 is therefore used to store larger impurities.

[0039] Furthermore, when the sewage reaches the vortex component 204 through the inlet hole 101a, the water flows out through the water inlet channel 204a. Since the water inlet channel 204a is spirally arranged, the water flow will drive the vortex component 204 and the screen bucket 203 to rotate. At this time, the flange 202a on the rotating disk 202 will rotate in the limiting groove 104 so as not to lock and affect the operation.

[0040] Specifically, as the sieve hopper 203 rotates, the large volume of impurities accumulated on the surface of the sieve hopper 203 will pass through the through hole 301 under the action of centrifugal force, which can greatly avoid the occurrence of blockage. Example 3

[0041] Reference Figure 1-4 This is the third embodiment of the present invention. Unlike the previous embodiment, it also includes a second filter layer 304 above the drain hole 303. The second filter layer 304 is a sand filter.

[0042] Specifically, the sand and gravel are made of quartz stone, which has the characteristics of high mechanical strength, strong interception capacity and good acid resistance. It removes inorganic and organic particles in the water that are in a dispersed suspended state, including various plankton, bacteria, filterable viruses, floating oil, emulsified oil, etc.
