Abstract
Description
Technical Field
[0001] This utility model relates to the field of deodorization technology, specifically to a deodorization structure and wastewater treatment equipment. Background Technology
[0002] With the improvement of people's living standards and the enhancement of public environmental awareness, the deodorization problem of sewage treatment plants is attracting more and more attention. The odor of sewage is caused by the products and incomplete products formed by the respiration or fermentation of proteins, fats and carbohydrates in sewage by microorganisms.
[0003] In existing technologies, most methods for treating odorous wastewater include biological filters, bio-trickling filters, bio-filter beds, wastewater deodorizers, activated carbon adsorption, chemical deodorization (such as chlorination disinfection and deodorization, acid and alkali deodorization, etc.), active oxygen deodorization, and soil deodorization, with activated carbon adsorption being the most commonly used.
[0004] Traditionally, most deodorizing boxes simply place activated carbon mesh inside the box. Since the activated carbon mesh remains stationary within the box's cavity, its working area has a relatively small radiation range. Using a single activated carbon mesh results in a long deodorization cycle and is not conducive to adsorbing odors from wastewater, leading to ineffective deodorization. Using multiple sets of activated carbon mesh increases production costs, and routine maintenance and replacement require dismantling all sets, increasing labor time. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a deodorization structure and sewage treatment equipment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An odor-removing structure includes an odor-removing box. A limiting frame is welded to the middle of the cavity of the odor-removing box, and a partition is placed on the limiting frame. The partition divides the interior of the odor-removing box into upper and lower cavities. A water inlet pipe is installed on one side of the top of the odor-removing box, and a drain pipe is installed on the other side of the bottom of the odor-removing box. A set of odor-removing meshes is installed on the top and bottom surfaces of the partition. A through hole is opened on one side of the top surface of the partition, and a water suction pipe is installed in the through hole, connecting the upper and lower cavities. The top of the water suction pipe is connected to a pump, which is installed on one side of the top surface of the partition. A water outlet pipe is installed on one end of the pump. A square hole is opened at the corner of the other side of the top surface of the partition, and a storage slot is opened above the square hole. A storage box is installed in the storage slot.
[0008] Further, straight grooves for connecting the deodorizing net are formed on the top and bottom surfaces of the partition baffle. Limit grooves are formed on two parallel side walls of the straight grooves. Springs are installed in the limit grooves. There are multiple groups of springs, and the multiple groups of springs are evenly distributed in the limit grooves. One end of each spring is connected to a limit block. The limit block has an inclined surface, and the inclined surface is located at one end of the limit block away from the limit groove and faces the outside of the straight groove cavity.
[0009] Further, grooves are formed on both side surfaces at one end of the deodorizing net. The size and position of the grooves correspond to those of the limit grooves one by one. The deodorizing net is a "hui"-shaped frame structure, and an adsorption net made of two layers of mesh-shaped activated carbon materials is installed in the cavity of the "hui"-shaped frame structure.
[0010] Further, the storage box is composed of two "hui"-shaped frames hinged to each other. A filter screen is installed in the cavities of the two "hui"-shaped frames of the storage box. One frame on one side of the storage box can be turned over. A threaded hole is formed at one end of the frame on one side of the storage box, and the threaded hole penetrates through the frame on one side of the storage box. A threaded hole is formed at the same position on the other frame of the storage box, and the position and size of the threaded hole with threads correspond to those of the threaded hole on the frame on one side. A bolt is screwed into the threaded hole.
[0011] Further, the water extraction pipe extends to the bottom of the cavity of the deodorizing box.
[0012] A sewage treatment device includes the above-mentioned deodorizing structure.
[0013] The utility model adopts the above technical solutions and has the following beneficial effects: By placing a partition baffle in the deodorizing box, a group of deodorizing nets are installed on the upper and lower surfaces of the partition baffle respectively. The deodorizing nets are mesh structures made of double-layer activated carbon materials, which increases the contact area when adsorbing odors. A pump is installed on one side of the partition baffle, which can upgrade the entire filter screen box into a circulating structure, increasing the contact between the sewage and the deodorizing nets and thus increasing the working efficiency of the deodorizing box. A storage box is placed at the corner of the partition baffle, and a solid deodorant is placed in the storage box to further increase the deodorizing efficiency. The device enables the sewage in the deodorizing box to circulate and flow, fully contact with the deodorizing box through a simple structure, and a solid deodorant is placed, increasing the working efficiency of the deodorizing box, and the entire device is relatively simple to disassemble and assemble.

[0022] Please refer to Figures 1 to 7 This utility model provides a technical solution: a deodorization structure, including a deodorization box 1. In the middle position of the cavity of the deodorization box 1, a limiting frame 16 is welded. A partition plate 2 is placed on the limiting frame 16. One side of the top of the deodorization box 1 is provided with a water inlet pipe 3, and the other side of the bottom of the deodorization box 1 is provided with a drain pipe 4. One group of deodorization nets 5 is installed on the top surface and the bottom surface of the partition plate 2 respectively. A through hole is opened on one side of the top surface of the partition plate 2, and a water suction pipe 8 is installed in the through hole. The top of the water suction pipe 8 is connected to a pump 7, and the pump 7 is installed on one side of the top surface of the partition plate 2. A water outlet pipe 9 is installed on the surface of one end of the pump 7. A square hole 14 is opened at the corner of the other side of the top surface of the partition plate 2, and a storage groove 15 is opened above the square hole 14. A storage box 6 is installed in the storage groove 15.
[0023] By placing the partition plate 2 in the deodorization box 1, one group of deodorization nets 5 is installed on the upper surface and the lower surface of the partition plate 2 respectively. The deodorization net 5 is a mesh structure made of double-layer activated carbon material, which increases the contact area when adsorbing odor. A pump 7 is installed on one side of the partition plate 2, which can upgrade the whole filter box into a circulating structure, increase the contact between the sewage and the deodorization net 5, and thus increase the working efficiency of the deodorization box 1. A storage box 6 is placed at the corner of the partition plate 2, and a solid deodorant is placed in the storage box 6 to further increase the deodorization efficiency.
[0024] In order to increase the deodorization efficiency, the deodorization net 5 is a "return" - shaped frame structure. An adsorption net made of two - layer grid - shaped activated carbon materials is installed in the cavity of the "return" - shaped frame structure. The storage box 6 is formed by hinging two "return" - shaped frames. A filter net is installed in the cavities of the two "return" - shaped frames of the storage box 6. One frame on one side of the storage box 6 can be flipped. A threaded hole is opened at one end of one frame on one side of the storage box 6, and the threaded hole penetrates through one side frame of the storage box 6. A threaded hole is opened at the same position of the other side frame of the storage box 6, and the position size of the threaded hole is corresponding to the position size of the threaded hole on one side frame. A bolt is screwed in the threaded hole.
[0025] During operation, the pump 7 is turned on to pump the sewage in the lower cavity of the deodorizing box 1 into the upper cavity, changing the entire structure from a static state to a circulating state, increasing the flow rate of the sewage, so that the sewage can fully contact the deodorizing net 5. The deodorizing net 5 is a mesh structure made of double-layer activated carbon, which increases the contact area when adsorbing odors. Solid deodorizing agents can be placed in the storage box 6 to further increase its deodorizing efficiency.
[0026] To secure the deodorizing mesh, straight grooves 10 for connecting the deodorizing mesh 5 are provided on the top and bottom surfaces of the partition 2. Limiting grooves 11 are provided on the two parallel sidewalls of the straight grooves 10. Springs 12 are installed in the limiting grooves 11. Multiple sets of springs 12 are evenly distributed in the limiting grooves 11. One end of the spring 12 is connected to a limiting block 13. The limiting block 13 has an inclined surface located at the end of the limiting block 13 away from the limiting groove 11 and facing out of the cavity of the straight groove 10. Grooves are provided on both sides of one end of the deodorizing mesh 5. The size and position of the grooves correspond one-to-one with the limiting grooves 11. First, install the deodorizing net 5 into the straight groove 10, so that it presses against the inclined surface of the limiting block 13 and causes the limiting block 13 to contract. When the deodorizing net 5 is installed at the bottom of the straight groove 10, the limiting block 13 reaches the groove of the deodorizing net 5, so that the spring 12 extends and holds the limiting block 13 in the groove of the deodorizing net 5, thereby limiting and fixing the deodorizing net 5.
[0027] This utility model relates to a wastewater treatment device, which includes the aforementioned deodorization structure.
[0028] In actual use, the deodorizing net 5 is first installed into the straight groove 10, so that it presses against the inclined surface of the limiting block 13, causing the limiting block 13 to contract. When the deodorizing net 5 is installed at the bottom of the straight groove 10, the limiting block 13 reaches the groove of the deodorizing net 5, thereby extending the spring 12 and holding the limiting block 13 in the groove of the deodorizing net 5, thus limiting and fixing the deodorizing net 5. The pump 7 is turned on to pump the sewage in the lower cavity of the deodorizing box 1 into the upper cavity, changing the entire structure from a static state to a circulating state, increasing the flow rate of sewage, so that the sewage can fully contact the deodorizing net 5. The deodorizing net 5 is a mesh structure made of double-layer activated carbon material, which increases the contact area when adsorbing odors. Solid deodorizing agents can be placed in the storage box 6 to further increase its deodorizing efficiency.
[0029] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
