[0003] Liquid medicine is usually filled into a container. When using, the personnel opens the container to pour the liquid medicine in the container into the tank for mixing, waiting for the dosing pump to extract and use. However, there is often some residual liquid medicine in the container. In order to avoid waste, water is injected into the container to mix with the residual liquid medicine, and then the mixed and diluted liquid medicine is poured into a special collecting device for subsequent use.
[0004] However, this collecting device is usually located outdoors. In order to facilitate the injection of diluted liquid medicine, a cover plate is not specially provided. Therefore, impurities such as leaves and insects in the natural environment can fall into the collecting device, resulting in a large amount of impurities inside the liquid medicine. Although the impurities can be filtered through a filter screen, the filter screen is easily clogged due to the large amount of impurities and the long-term exposure of the device, causing the liquid medicine to be unable to flow freely. SUMMARY
[0005] The main purpose of the utility model is to provide a dosing pump residual liquid collecting device. The collecting tank and the storage tank are separated by a filter screen. When the liquid level in the collecting tank is higher than the filter screen, the sedimentable impurities in the collecting tank will sink to the bottom of the collecting tank and be lower than the filter screen, and the floatable impurities in the collecting tank will float above the filter screen, thereby avoiding the impurities in the collecting tank from clogging the mesh holes of the filter screen and ensuring that the liquid medicine in the collecting tank can normally pass through the through hole into the storage tank.
[0006] To achieve the above purpose, the utility model adopts the technical scheme of:
[0007] A dosing pump residual liquid collecting device includes a base. The base has a collecting tank and a storage tank. The collecting tank has an opening at the top. A through hole is provided between the storage tank and the collecting tank. A filter screen is detachably fixed to the side of the through hole in the collecting tank. The top of the filter screen is lower than the top opening of the collecting tank, and the bottom of the filter screen is higher than the inner bottom of the collecting tank. A first pipeline is connected to the base and communicates with the storage tank.
[0008] Further, the filter screen is fixed to the inner wall of the collecting tank by bolts, and the filter screen is vertically arranged.
[0009] Further, the base top is fixed with a limiting frame body, and the limiting frame body is located on the opening of the collecting groove.
[0010] Further, the inner bottom of the storage groove has a slope, and the water inlet of the first pipeline is connected to the lowest point of the slope.
[0011] Further, the inner bottom of the collecting groove is provided with a foreign matter discharging hole communicated with the storage groove, and a plug is threadedly connected in the foreign matter discharging hole.
[0012] Further, the plug is fixed with a horn body at one end.
[0013] Further, the first pipeline is provided with a first valve.
[0014] Further, the first pipeline between the first valve and the base is connected with a second pipeline, and the second pipeline is provided with a second valve.
[0015] Compared with the prior art, the utility model has the advantages of the following:
[0016] The collecting groove and the storage groove are separated by the filter screen, when the liquid level in the collecting groove is higher than the filter screen, the sedimentable impurities in the collecting groove sink to the inner bottom of the collecting groove and are lower than the filter screen, and the floatable impurities in the collecting groove float above the filter screen, so that the mesh holes of the filter screen are prevented from being blocked by the impurities in the collecting groove, and the liquid in the collecting groove can normally enter the storage groove through the through hole.
[0017] When the liquid medicine enters the collecting groove, the liquid medicine enters the storage groove through the through hole, in this process, the liquid medicine in the collecting groove flows intermittently because the liquid medicine is added to the collecting groove intermittently, so that the impurities are not easy to adhere to the filter screen, and when the liquid medicine stops being added, the liquid level in the collecting groove is higher than the filter screen, so that the impurities do not have too much contact with the filter screen, thereby further reducing the possibility of the filter screen being blocked.

DETAILED DESCRIPTION
[0024] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0025] As shown in Figures 1-3 A residual liquid collecting device of a medicine adding pump, comprising a base 1, a collecting tank 2 and a storage tank 5 are formed in the base 1, the collecting tank 2 has an opening at the top, a through hole 6 is formed between the storage tank 5 and the collecting tank 2, a filter screen 7 is detachably fixed to the side of the through hole 6 in the collecting tank 2, the top of the filter screen 7 is lower than the top opening of the collecting tank 2, and the bottom of the filter screen 7 is higher than the inner bottom of the collecting tank 2, and a first pipeline 3 is further connected to the base 1 and communicates with the storage tank 5.
[0026] In the embodiment, water is poured into the container of the residual liquid, so that the water is mixed with the liquid, and then the mixed liquid is poured into the collecting tank 2, when the liquid level in the collecting tank 2 reaches the position of the through hole 6, the liquid will flow into the storage tank 5, and the filter screen 7 can intercept the impurities in the collecting tank 2, so as to avoid the impurities entering the storage tank 5, and the liquid in the storage tank 5 can be sucked by the medicine adding pump through the first pipeline 3, so as to send the filtered liquid into the sewage treatment line for use.
[0027] Preferably, during use, the liquid level in the collecting tank 2 should be maintained higher than the filter screen 7, at this time, the sedimentable impurities in the collecting tank 2 will sink to the bottom of the collecting tank 2 and below the filter screen 7, and the floatable impurities in the collecting tank 2 will float above the filter screen 7, so as to avoid the impurities in the collecting tank 2 blocking the mesh holes of the filter screen 7.
[0028] As shown in Figure 2 The filter screen 7 is fixed on the inner wall of the collecting tank 2 by bolts, therefore, the filter screen 7 can be easily disassembled for cleaning, and the filter screen 7 is vertically arranged, which can reduce the adhesion of impurities.
[0029] The base 1 has a limiting frame 4 fixed on top and the limiting frame 4 is located on the opening of the collection tank 2. When the liquid in the collection tank 2 overflows, the limiting frame 4 can restrain the overflowing liquid and prevent the liquid from flowing to the ground. Thus, when the liquid in the collection tank 2 is pumped away by the dosing pump, the overflowing liquid can flow back into the collection tank 2.
[0030] like Figure 2 As shown, the storage tank 5 is located inside the base 1. The bottom of the storage tank 5 has an inclined surface 501. The inlet of the first pipe 3 is connected to the lowest point of the inclined surface 501. The first pipe 3 is connected to the dosing pump. A first valve 11 is installed on the first pipe 3. When the valve is opened, the dosing pump can draw liquid from the storage tank 5. Since the inlet of the first pipe 3 is connected to the lowest point of the inclined surface 501, the liquid in the storage tank 5 can be easily discharged through the first pipe 3.
[0031] like Figure 2 and Figure 3 As shown, a discharge hole 8, which communicates with the storage tank 5, is provided on one side of the bottom of the collection tank 2. A plug 9 is threaded into the discharge hole 8. A second pipe 13 is connected to the first pipe 3 located between the first valve 11 and the base 1. A second valve 12 is provided on the second pipe 13. When it is necessary to clean the collection tank 2 and the storage tank 5, the first valve 11 can be closed and the second valve 12 can be opened. The plug 9 can be unscrewed from the discharge hole 8. At this time, the liquid and impurities in the collection tank 2 can enter the storage tank 5 through the discharge hole 8 and then be discharged through the first pipe 3 and the second pipe 13, so as to clean the collection tank 2 and the storage tank 5 by the flow of liquid.
[0032] When the dosing pump draws liquid from the storage tank 5, the second valve 12 should be closed and the first valve 11 should be opened.
[0033] Among them, such as Figure 2 As shown, one end of the plug 9 is fixed with a ram's horn rod 10, which allows personnel to easily rotate the plug 9.
[0034] The working principle is that first, the first pipeline 3 is connected to the dosing pump, and then the second pipeline 13 is connected to the impurity discharge pipeline. When the residual liquid medicine in the liquid medicine container needs to be treated, water can be poured into the residual liquid medicine container, so that the water and the liquid medicine are mixed, and then the mixed liquid is poured into the collecting groove 2, and the water level in the collecting groove 2 is controlled to be higher than the filter screen 7. At this time, the sedimentable impurities in the collecting groove 2 can sink to the bottom of the collecting groove 2 and below the filter screen 7, and the floatable impurities in the collecting groove 2 can float above the filter screen 7, so as to avoid that the impurities in the collecting groove 2 block the mesh holes of the filter screen 7. In this process, the liquid in the collecting groove 2 flows into the storage tank 5 through the through hole 6, and the filter screen 7 can intercept the impurities in the collecting groove 2, so as to avoid that the impurities enter the storage tank 5. Next, when the liquid in the storage tank 5 and the collecting groove 2 needs to be used, the personnel should first use a strainer or the like to salvage the impurities floating on the top of the liquid in the collecting groove 2, and then control the dosing pump to work, so that the liquid in the storage tank 5 can be sucked by the dosing pump through the first pipeline 3, so as to send the liquid in the storage tank 5 into the sewage treatment line for use. As the amount of the liquid in the storage tank 5 decreases, the liquid in the collecting groove 2 flows into the storage tank 5, until the liquid level in the collecting groove 2 is lower than the through hole 6.
[0035] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
