[0002] Wastewater treatment, simply put, is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering. It is also increasingly becoming a part of everyday life. We generate a large amount of wastewater every day. If this wastewater is not treated, it can only be reused after being purified by nature, which is inefficient and cannot meet the ever-increasing water demand. A crucial step in wastewater treatment is adding chemicals to the wastewater, a process that requires the use of chemical dosing equipment.

[0003] Currently available wastewater treatment dosing devices have the following problems during operation:

[0004] Existing wastewater treatment dosing devices typically have a replenishment tank. Water and chemicals are added to the replenishment tank, thoroughly mixed, and then pumped into the wastewater tank. However, the chemicals in the replenishment tank are usually not fully mixed, leaving some particles or sediment. If these substances are not treated and are directly pumped into the dosing pump, the pump will become clogged over time. Cleaning the dosing pump is troublesome and reduces the efficiency of wastewater treatment. Utility Model Content

[0005] The purpose of this utility model is to provide a dosing device for sewage treatment, in order to solve the problem mentioned in the background art that the existing dosing devices for sewage treatment generally have a dosing tank. Water and chemicals are added to the dosing tank and thoroughly stirred before being transported to the sewage tank by a dosing pump. However, the chemicals in the dosing tank are generally not thoroughly stirred, and some particles or sediments will remain. These substances are directly transported to the dosing pump without treatment, which will cause the dosing pump to become clogged over time. Cleaning the dosing pump is troublesome and will reduce the efficiency of sewage treatment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dosing device for sewage treatment, comprising a support frame, a mixing tank mounted on the upper wall of the support frame, a dosing pump mounted on the upper wall of the support frame, a connecting pipe provided on the outer wall of the mixing tank, a filter mechanism provided at one end of the connecting pipe, a sealing component provided at one end of the connecting pipe, and a discharge pipe mounted on one side of the filter mechanism;

[0007] The filtration mechanism includes a connecting pipe, a filter pipe, a first filter hole, a filter plate, a second filter hole, a threaded hole, and a plug. One end of the connecting pipe is provided with a connecting pipe, and the inner wall of the connecting pipe is connected to the filter pipe. The upper end of the filter pipe has a first filter hole, the inside of the filter pipe is provided with a filter plate, the outer wall of the filter plate has a second filter hole, the lower end of the filter pipe has a threaded hole, and the lower end of the filter pipe is threadedly connected to a plug.

[0008] Preferably, the first filter holes are evenly distributed at the upper end of the filter tube, and the filter plate is disposed on the central axis of the filter tube.

[0009] Preferably, the second filter holes are evenly distributed on the outer wall of the filter plate.

[0010] Preferably, the sealing assembly includes a first connecting plate, a placement groove, a sealing ring, a second connecting plate, and a sealing groove. One end of the connecting pipe is connected to the first connecting plate, the outer wall of the first connecting plate has a placement groove, the inner wall of the placement groove is fitted with a sealing ring, and one end of the connecting pipe is connected to the second connecting plate, the outer wall of the second connecting plate has a sealing groove.

[0011] Preferably, the inner wall dimensions of the placement groove match the outer wall dimensions of the sealing ring, and the inner wall dimensions of the sealing groove match the outer wall dimensions of the sealing ring.

[0012] Preferably, the first connecting plate is symmetrically arranged with respect to the central axis of the connecting pipe, and the placement groove is symmetrically arranged with respect to the central axis of the connecting pipe.

[0013] Preferably, the sealing rings are arranged symmetrically about the central axis of the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This sewage treatment dosing device, through the arrangement of a connecting pipe, a filter pipe, a first filter hole, a filter plate, a second filter hole, a threaded hole, and a pipe plug, allows for the dosing of chemicals into sewage. First, the relevant operator adds the chemicals and water to the mixing tank and stirs them. Then, the dosing pump is started via an external control button. The chemical solution enters the connecting pipe from the connecting pipe. First, the chemical solution undergoes preliminary filtration of impurities in the chemical solution through the second filter hole on the filter plate. Then, the filtered chemical solution undergoes a second filtration through the first filter hole at the upper end of the filter pipe before entering the sewage treatment plant. The wastewater is discharged through the discharge pipe and then transported to the dosing pump, which then transports it to the wastewater tank for treatment. During this process, impurities will settle at the bottom of the filter pipe. When it is necessary to treat the impurities in the filter pipe, the operator can simply remove the connecting pipe for rinsing. Before using the device, the operator aligns the two ends of the sealing ring with the placement groove and the sealing groove, respectively. Then, the first connecting plate and the second connecting plate are connected and fixed with bolts and nuts. The sealing groove and the placement groove will compress the sealing ring, which can prevent the chemical from leaking out from the connection between the connecting pipe and the discharge pipe to a certain extent, thus achieving a sealing effect.

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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a dosing device for sewage treatment, including a support frame 1, a mixing tank 2 installed on the upper wall of the support frame 1, a dosing pump 3 installed on the upper wall of the support frame 1, a connecting pipe 4 provided on the outer wall of the mixing tank 2, a filter mechanism 5 provided at one end of the connecting pipe 4, a sealing component 6 provided at one end of the connecting pipe 4, and a discharge pipe 7 installed on one side of the filter mechanism 5.

[0022] The filtration mechanism 5 includes a connecting pipe 501, a filter pipe 502, a first filter hole 503, a filter plate 504, a second filter hole 505, a threaded hole 506, and a pipe plug 507. One end of the connecting pipe 4 is provided with the connecting pipe 501, and the filter pipe 502 is connected through the inner wall of the connecting pipe 501. The upper end of the filter pipe 502 has the first filter hole 503, the inside of the filter pipe 502 is provided with the filter plate 504, and the outer wall of the filter plate 504 has the second filter hole 505. The lower end of the filter pipe 502 has the threaded hole 506, and the lower end of the filter pipe 502 is threadedly connected to the pipe plug 507. The filter mechanism 5 utilizes the connecting pipe 501, filter pipe 502, first filter hole 503, filter plate 504, second filter hole 505, threaded hole 506, and pipe plug 507. The setup is as follows: When adding chemicals to wastewater, the operator first adds the chemicals and water to the mixing tank 2 and stirs it. Then, the dosing pump 3 is started via an external control button. The chemicals enter the connecting pipe 501 through the connecting pipe 4. First, the chemicals pass through the second filter hole 505 on the filter plate 504 to filter the impurities in the chemicals. Then, the filtered chemicals pass through the first filter hole 503 at the top of the filter pipe 502 for the first filtration and enter the discharge pipe 7. The discharge pipe 7 then transports the chemicals to the dosing pump 3, which then transports them to the wastewater tank for wastewater treatment. During this process, impurities will settle to the bottom of the filter pipe 502. When it is necessary to treat the impurities in the filter pipe 502, the operator can remove the connecting pipe 501 for rinsing.

[0023] Furthermore, the first filter holes 503 are evenly distributed at the upper end of the filter tube 502, and the filter plate 504 is set on the central axis of the filter tube 502. The first filter holes 503 can be used to filter impurities from the medicine.

[0024] Furthermore, the second filter holes 505 are evenly distributed on the outer wall of the filter plate 504, and the medicine solution can be filtered for impurities through the setting of the second filter holes 505.

[0025] Furthermore, the sealing assembly 6 includes a first connecting plate 601, a placement groove 602, a sealing ring 603, a second connecting plate 604, and a sealing groove 605. One end of the connecting pipe 501 is connected to the first connecting plate 601. The outer wall of the first connecting plate 601 has a placement groove 602, and the inner wall of the placement groove 602 is fitted with a sealing ring 603. One end of the connecting pipe 4 is connected to the second connecting plate 604. The outer wall of the second connecting plate 604 has a sealing groove 605. The sealing assembly 6 passes through the first connecting plate 601 and the placement groove 602. Before using the device, the operator aligns the two ends of the sealing ring 603 with the placement groove 602 and the sealing groove 605 respectively. Then, the first connecting plate 601 and the second connecting plate 604 are connected and fixed with bolts and nuts. The sealing groove 605 and the placement groove 602 will squeeze the sealing ring 603, which can prevent the medicine from leaking out from the connection between the connecting pipe 501 and the connecting pipe 4 and the discharge pipe 7 to a certain extent, thus achieving a sealing effect.

[0026] Furthermore, the inner wall dimensions of the placement groove 602 match the outer wall dimensions of the sealing ring 603, and the inner wall dimensions of the sealing groove 605 match the outer wall dimensions of the sealing ring 603. The placement groove 602 allows the sealing ring 603 to enter the inner wall of the placement groove 602.

[0027] Furthermore, the first connecting plate 601 is symmetrically arranged with respect to the central axis of the connecting pipe 501, and the placement groove 602 is symmetrically arranged with respect to the central axis of the connecting pipe 501. The arrangement of the first connecting plate 601 allows the first connecting plate 601 to come into contact with the medicine.

[0028] Furthermore, the sealing ring 603 is symmetrically arranged around the central axis of the connecting pipe 501.

[0029] Working principle: When adding chemicals to wastewater, the operator first adds the chemicals and water to the mixing tank 2 and stirs it. Then, the dosing pump 3 is started via an external control button. The chemical solution enters the connecting pipe 501 through the connecting pipe 4. First, the chemical solution passes through the second filter hole 505 on the filter plate 504 to initially filter impurities. Then, the filtered chemical solution passes through the first filter hole 503 at the upper end of the filter pipe 502 for a second filtration and enters the discharge pipe 7. From there, it is transported to the dosing pump 3, which then delivers it to the wastewater tank for treatment. This process... Impurities will settle to the bottom of the filter tube 502. When it is necessary to treat the impurities in the filter tube 502, the operator can simply remove the connecting tube 501 for rinsing. Before using the device, the operator aligns the two ends of the sealing ring 603 with the placement groove 602 and the sealing groove 605 respectively, and then connects and fixes the first connecting plate 601 and the second connecting plate 604 with bolts and nuts. The sealing groove 605 and the placement groove 602 will squeeze the sealing ring 603, which can prevent the medicine from leaking out from the connection between the connecting tube 501 and the connecting tube 4 and the discharge tube 7 to a certain extent, thus achieving a sealing effect.
