Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an automatic spraying sewage treatment pool. Background Art

[0002] During the sewage treatment process, it is usually necessary to defoam the foam generated by the aeration device or other factors. For example, in the aerobic treatment stage of sewage, the foam is often treated by spraying. However, some sewage treatment tanks in the prior art often require manual real-time observation of the sewage treatment tanks to control the spraying of the spraying device, or to allow the spraying device to spray continuously for 24 hours, resulting in a waste of water resources and manpower. Patent No. CN201921759911.7 discloses a foam automatic spraying device for a sewage pool biochemical system, which includes a moving rod movably arranged on the inner wall relative to the aerobic pool, the moving rod slides in a guide groove opened along the height direction of the aerobic pool, and the lower surface of the moving rod is provided with an infrared transmitting end and an infrared receiving end along its axial direction. When the infrared transmitting end and the infrared receiving end detect bubbling on the liquid surface of the aerobic pool, the battery valve is energized, so that the water in the clean water pool passes through the water supply pipe and the spray pipe in turn under the action of the submersible pump, and enters the aerobic pool through the nozzle. The sprayed water breaks the bubbles, so that there is no need for manual observation, and the bubble situation in the aerobic pool is automatically checked and the aerobic pool is defoamed, saving time and effort. However, the above patent still has the following disadvantages: 1. It is necessary to groove the sewage treatment tank (aerobic tank), and when it is used in an already built sewage treatment tank, it needs to be modified; 2. It is necessary to move a moving rod on the relative inner wall of the sewage treatment tank. When it is used in a larger sewage treatment tank, a longer moving rod is required, and the manufacturing difficulty, cost and movement difficulty of the longer moving rod increase accordingly; the applicability is narrow, and the practicality needs to be improved.

[0003] Based on this, the applicant considered designing a practical and widely applicable automatic sprinkler sewage treatment pool. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a practical and widely applicable automatic spray sewage treatment pool.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An automatic spraying sewage treatment pool comprises a treatment pool body and a spraying mechanism for spraying a foam layer above a water body in the treatment pool body, and also comprises a floating mechanism, wherein the floating mechanism comprises a floating member floating above the water body and a distance measuring member fixedly connected above the floating member, wherein the distance measuring member is used to measure the distance between the distance between the distance measuring member and the foam layer, and the distance measuring member is communicatively connected to the spraying device.

[0007] The working principle and advantages of an automatic spraying sewage treatment tank in this technical solution are:

[0008] When in use, the floating mechanism is directly placed in the treatment pool body. When the water level in the treatment pool body changes, the floating member drives the distance measuring member fixed thereon to rise or fall with the change of the water level in the treatment pool. When foam is generated in the treatment pool body due to the aeration device or other factors, the foam accumulates above the water body to form a foam layer. The distance measuring member can measure the distance between it and the foam layer in real time and send it to the spraying device. This distance reflects the thickness or height of the foam layer. When the thickness of the foam layer exceeds the preset threshold, the spraying device performs a spraying operation to break up the foam layer by spraying water flow to achieve automatic defoaming. The spraying is only started when needed, avoiding the waste of water resources and eliminating the need for real-time observation by staff. This solution is suitable for treatment pool bodies with sufficient buoyancy of the water body. It does not require the treatment pool to be modified, and is suitable for larger treatment pools. It is also easier to install and maintain, and has wide applicability, high practicality, and high flexibility.

[0009] Furthermore, the floating component includes a floating barrel, a mounting plate is fixedly connected above the floating barrel, and the distance measuring component is fixedly connected to the bottom side of the mounting plate.

[0011] Furthermore, a conical cover is fixedly connected to the top side of the mounting plate, and the distance measuring component is located directly below the conical cover.

[0012] Furthermore, the floating mechanism also includes a lifting member, which is fixedly installed on the top side of the floating barrel, and the telescopic end of the lifting member is fixedly connected to the bottom side of the mounting plate.

[0013] Furthermore, the floating mechanism also includes a stud, a weight ring and a limiting ring, the stud is fixedly connected to the bottom side of the floating barrel, the weight ring is sleeved on the outside of the stud, and the limiting ring is threadedly connected to the stud.

[0030] Refer to Figure 1 to Figure 6 The present embodiment provides an automatic spraying sewage treatment pool, including a treatment pool body 10 and a spraying mechanism for spraying a foam layer 12 above a water body 11 in the treatment pool body 10, and further including a floating mechanism 300, the floating mechanism 300 including a floating member floating above the water body 11 and a distance measuring member 350 fixedly connected above the floating member, the distance measuring member 350 being used to measure the distance between it and the foam layer 12, and the distance measuring member 350 being communicatively connected to the spraying device.

[0031] In this embodiment, the floating mechanism 300 is directly placed in the treatment pool body 10 when in use. When the water level of the water body 11 in the treatment pool body 10 changes, the floating member drives the distance measuring member 350 fixedly connected thereto to rise or fall with the change of the water level of the water body 11; when foam is generated in the treatment pool body 10 due to the aeration device or other factors, the foam accumulates above the water body 11 to form a foam layer 12. The distance measuring member 350 can measure the distance between it and the foam layer 12 in real time and send it to the spraying device. This distance reflects the thickness or height of the foam layer 12. When the thickness of the foam layer 12 exceeds the preset threshold, the spraying device performs a spraying operation to break up the foam layer 12 through the spraying water flow to achieve automatic defoaming. The spraying is only started when needed, avoiding the waste of water resources and eliminating the need for real-time observation by staff. This solution is applicable to the treatment pool body 10 with sufficient buoyancy of the water body 11, does not require the treatment pool to be modified, and is applicable to treatment pools of larger sizes.

[0033] Preferably, if Figure 2 to Figure 5 As shown, the floating mechanism 300 also includes a connecting rod 330, the bottom end of the connecting rod 330 is fixedly connected to the top side of the floating barrel 310, and the top end is fixedly connected to the bottom side of the mounting plate 340, and a number of evenly arranged floating barrels 310 are distributed circumferentially on the outer side of the mounting plate 340; the connecting rod 330 ensures a stable connection between the floating barrel 310 and the mounting plate 340, and a number of evenly arranged floating barrels 310 are distributed circumferentially on the outer side of the mounting plate 340 to ensure that the floating mechanism 300 has better stability and balance on the water surface, so that the floating mechanism 300 can still maintain a relatively stable posture under the influence of the fluctuations of the water body 11; specifically, the floating barrel 310 includes four.

[0034] Preferably, if Figure 2 to Figure 6 As shown, a conical cover 360 is fixedly connected to the top side of the mounting plate 340 , and the distance measuring component 350 is located directly below the conical cover 360 ; the conical cover 360 protects the distance measuring component 350 inside thereof and allows the spraying water to flow quickly downward into the water body 11 .
