Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mineral processing and dispensing, and more particularly relates to a dispensing device for polymer powder inhibitors. Background Art
[0002] Polymer powder inhibitors, due to their excellent inhibitory properties against magnesium / aluminum silicate gangue, which tends to float and sludge, are widely used in various industrial fields, such as sulfide mineral flotation. Currently, the dispensing equipment for this type of agent still uses the most conventional flotation dispensing method, which involves first adding water to a mixing tank, then adding the agent directly into the mixing tank in a certain proportion. During the addition process, the agitator remains on to fully stir the contents. Once the concentration is uniform, the agent is pumped directly into the flotation tank using a dosing pump.
[0003] However, in actual use, we found that this dispensing method is not suitable for drugs such as polymer powder inhibitors. Polymer powder inhibitors usually have a large molecular weight, which makes them difficult to fully disperse during the dissolution process. If too much polymer powder inhibitor is added to the water at one time, the part that first contacts the water will swell rapidly, increasing its surface area, and then enveloping the part that does not contact the water, forming insoluble clumps, resulting in excessive precipitation of the drug solution. As a result, during the dispensing process, the drug solution concentration becomes obviously uneven. In this case, manual adjustment of the dosing valve is required. However, more often, the drug tube will be blocked and the drug solution flow will be cut off, requiring manual cleaning and unblocking of the dosing tube. In these cases, the large molecular weight of the drug, unsuitable dissolution conditions, high insoluble matter, and uncontrollable drug solution concentration and dosing amount lead to the dispersion of the polymer drug and the easy formation of clumps. Uneven dosing speed, uneven concentration, and unstable dosing amount have a significant impact on the flotation separation process, deteriorating the flotation effect, and also causing unnecessary waste of water, electricity, and manpower. Utility Model Content
[0004] The purpose of the utility model is to provide a dispensing device for polymer powder inhibitors, aiming to solve the problem that the existing dispensing devices are prone to agglomeration during the dispensing process of such substances, resulting in unsatisfactory dispensing.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A dispensing device for polymer powder inhibitors includes a drug stirring tank, a drug discharge pipe is connected to the lower part of the drug stirring tank, and a drug discharge pump is installed on the drug discharge pipe. It is characterized in that a drug screen is installed at the upper inlet of the drug stirring tank, and a drug screen is installed at the inlet position of the drug discharge pipe in the drug stirring tank.
[0007] As a further preference of the above technical solution, it also includes a medicine storage tank, which is connected to the medicine mixing tank through the medicine outlet pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. The present invention is an improvement on the existing dispensing device. A new medicine screen and a medicine screen are added to the medicine mixing tank. The medicine screen is installed at the upper inlet position of the medicine mixing tank. When the added powder medicine passes through the medicine screen, the larger particles therein are intercepted and screened, and the finer particles leak to the bottom of the tank. This can not only control the particle size of the powder medicine entering the tank, but also ensure a more uniform distribution of the medicine particle size, thereby improving the stirring and dissolving effect of the medicine; the medicine screen is installed at the lower outlet position of the medicine mixing tank. After the stirring is completed, the mixed medicine liquid needs to be further screened by the medicine screen before entering the medicine outlet pipe. The medicine screen can intercept the lumps formed during the stirring process and the insoluble impurities in the medicine liquid, reduce the solid matter content in the mixed medicine liquid entering the medicine outlet pipe, and prevent the pipe from being blocked. The present invention can significantly improve the solubility of the medicine and the fineness of the medicine liquid through the dual filtering and interception effect of the medicine screen and the medicine screen, thereby providing favorable conditions for subsequent flotation.
[0017] 2. The utility model is additionally provided with a medicine storage tank, which is used to store the dissolved mixed medicine liquid. When there is a demand for medication, the medicine storage tank can immediately provide the dissolved medicine liquid through the medication tube, without having to wait for the medicine mixing tank to prepare the medicine from the beginning. When the amount of medicine liquid in the medicine storage tank is reduced, the medicine mixing tank will be replenished in time. The volumetric medication method can be used to administer medicine more quickly in an emergency, which is convenient and quick, and can play a great role in dealing with special situations.
[0018] 3. The utility model is also equipped with a filter screen at the end of the medicine outlet pipe in the medicine storage tank, so that the medicine liquid entering the medicine storage tank can be further filtered through the filter screen, and cooperate with the medicine screen and the medicine screen to form a triple filtration interception, thereby maximizing the solubility and fineness of the medicine liquid, avoiding pipeline blockage and laying a good foundation for subsequent flotation.
[0019] 4. The utility model is also provided with an overflow pipe between the medicine mixing tank and the medicine storage tank. The overflow pipe is used for the return of the medicine liquid from the medicine storage tank to the medicine mixing tank, so that a medicine liquid circulation is formed between the two, maintaining the continuous flow of the medicine liquid in the circulation pipeline to avoid pipeline blockage. At the same time, the circulating flow can also dissolve and filter the medicine liquid multiple times to further improve the dispensing effect.
[0020] 5. The utility model also has an emptying pipe connected to the medicine outlet pipe between the medicine mixing tank and the medicine outlet pump. When the medicine mixing tank needs to be cleaned, the remaining medicine liquid in the tank can be emptied through the emptying pipe.
[0021] 6. The utility model is provided with corresponding control valves on each pipeline to control and adjust the pipeline passage and the flow of liquid medicine through the pipeline, so as to ensure the stability of the liquid medicine flow on each pipeline and the quality of the liquid medicine.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Example 1
[0027] like Figure 1 The dispensing device for polymer powder inhibitors shown in the figure includes a pharmaceutical mixing tank 1, in which a stirrer 15 is vertically installed. The upper end of the stirrer 15 passes through the pharmaceutical mixing tank 1 and is connected to a drive motor 16. The stirrer 15 is provided with multiple layers of stirring blades 17. In this embodiment, the stirring blades 17 are provided with three layers. Of course, in more embodiments, the number of layers of the stirring blades 17 can be appropriately increased or decreased according to the size of the pharmaceutical mixing tank 1 and the working requirements; the pharmaceutical mixing tank 1 is connected to a drug discharge pipe 2 at the lower part, and a drug discharge pump 3 is installed on the drug discharge pipe 2. The drug discharge pump 3 is a conventional drive pump body, and its installation structure is as follows: the drug discharge pipe 2 is divided into two sections, one of which is connected to the drug mixing tank 1 and the liquid inlet of the drug discharge pump 3 at both ends, and the other is connected to the liquid outlet of the drug discharge pump 3 and the flotation tank or the drug storage tank 6 mentioned later at both ends; a drug screen 4 is installed at the upper inlet of the drug mixing tank 1, and a drug screen 5 is installed at the inlet position of the drug discharge pipe 2 in the drug mixing tank 1.
[0028] Furthermore, a drug discharge control valve 12 is installed on the drug discharge pipe 2 between the drug mixing tank 1 and the drug discharge pump 3, which is used to open and close the drug liquid flow path in the drug discharge pipe 2, and can control the drug liquid flow in the pipeline by adjusting the valve opening and closing degree to ensure a stable drug discharge amount.
[0029] It is worth noting that the drug screen 4 in this embodiment is a screen for pure solid substances, and the drug screen 5 is a screen for solid-liquid mixtures. The mesh of the drug screen 5 is finer than that of the drug screen 4, and both use conventional screen selection.
[0030] The present embodiment is improved on the basis of the existing dispensing device. A medicine screen 4 and a medicine screen 5 are newly added to the medicine mixing tank 1. The medicine screen 4 is installed at the upper inlet position of the medicine mixing tank 1. When the added powder medicine passes through the medicine screen 4, the larger particles therein are intercepted and screened out, and the finer particles leak to the bottom of the tank. This can not only control the particle size of the powder medicine entering the tank, but also ensure that the particle size distribution of the medicine is more uniform, thereby improving the stirring and dissolving effect of the medicine; the medicine screen 5 is installed at the lower outlet position of the medicine mixing tank 1. After the stirring is completed, the mixed medicine liquid needs to be further screened by the medicine screen 5 before entering the medicine outlet pipe 2. The medicine screen 5 can intercept the lumps formed during the stirring process and the insoluble impurities in the medicine liquid, reduce the solid matter content in the mixed medicine liquid entering the medicine outlet pipe 2, and prevent the pipe from being blocked. The utility model can significantly improve the solubility of the medicine and the fineness of the medicine liquid through the dual filtering and interception effect of the medicine screen 4 and the medicine screen 5, providing favorable conditions for subsequent flotation.
[0031] Example 2
[0032] This embodiment is a further supplementary solution to embodiment 1. This embodiment also includes a medicine storage tank 6, which is connected to the medicine mixing tank 1 through the medicine outlet pipe 2. In this embodiment, the connection position between the medicine outlet pipe 2 and the medicine storage tank 6 is the top of the medicine storage tank 6, and the medicine storage tank 6 is connected to a drug delivery pipe 7; the medicine storage tank 6 is used to store the dissolved mixed medicine liquid. When there is a demand for drug delivery, the medicine storage tank 6 can immediately provide the dissolved medicine liquid through the drug delivery pipe 7 without waiting for the medicine mixing tank 1 to start the drug delivery process from the beginning. When the amount of medicine liquid in the medicine storage tank 6 is reduced, the medicine mixing tank 1 will be replenished in time. The volumetric drug delivery method can deliver medicine more quickly in an emergency, which is convenient and quick, and can play a great role in dealing with special situations.
[0033] Furthermore, a drug administration control valve 8 is installed on the drug administration tube, which is used to open and close the drug liquid flow path in the drug administration tube 7, and can control the drug liquid flow in the pipeline by adjusting the valve opening and closing degree to ensure a stable drug administration amount.
[0034] Furthermore, in this embodiment, a filter screen 9 is installed at the end of the drug outlet pipe 2 located in the drug storage tank 6. When the dissolved and mixed drug liquid in the drug mixing tank 1 enters the drug storage tank 6 through the drug outlet pipe 2, it will be further filtered by the filter screen 9. It cooperates with the drug screen 4 and the drug screen 5 in the drug mixing tank 1 to form a triple filtration interception, which maximizes the solubility and fineness of the drug solution, avoids pipeline blockage, and lays a good foundation for subsequent flotation.
[0035] Example 3
[0036] This embodiment is a further supplementary solution to Example 2. In this embodiment, an overflow pipe 10 is further provided between the medicine mixing tank 1 and the medicine storage tank 6. The overflow pipe 10 is used for the backflow of the medicine liquid from the medicine storage tank 6 to the medicine mixing tank 1, so that a medicine liquid circulation is formed between the two, and the continuous flow of the medicine liquid in the circulation pipeline is maintained to avoid pipeline blockage. At the same time, the circulating flow can also dissolve and filter the medicine liquid multiple times to further improve the dispensing effect; an overflow control valve 11 is installed on the overflow pipe 10, which is used to switch the medicine liquid flow path in the overflow pipe 10, and the flow rate of the medicine liquid in the pipeline can be controlled by adjusting the valve opening and closing degree to ensure the stability of the overflow medicine liquid amount.
[0037] More specifically, both ends of the overflow pipe 10 are respectively connected to the upper positions of the medicine mixing tank 1 and the medicine storage tank 6, and the communication position of the overflow pipe 10 and the medicine mixing tank 1 is lower than the height position of the medicine screen 4.
[0038] When the dispensing device in this embodiment is used for the first time, the medicine mixing tank 1 will output enough mixed medicine liquid to the medicine storage tank 6 under continuous operation until the medicine storage tank 6 is completely full, and then stop adding medicine into the medicine mixing tank 1. At this time, the overflow control valve 11 on the overflow pipe 10 is opened to allow the medicine liquid in the medicine storage tank 6 to circulate back to the medicine mixing tank 1. At this time, a certain amount of medicine liquid will circulate between the medicine mixing tank 1 and the medicine storage tank 6, thereby improving the solubility while preventing pipeline blockage; when there is a demand for medication, the medication control valve 8 on the medication pipe 7 is opened, and the medicine storage tank 6 can then output medication; at the same time, in order to prevent the liquid level in the medicine storage tank 6 from being lower than the connecting position of the overflow pipe 10 in the medicine storage tank 6, when the medicine storage tank 6 is medication, it is necessary to start adding medicine into the medicine mixing tank 1 for dispensing to compensate for the loss of medicine liquid in the medicine storage tank 6, so as to form a good and sustainable medicine liquid circulation system.
[0039] Example 4
[0040] This embodiment is a further supplementary solution to Example 1 and a further optimization of the above technical solution. The medicine discharge pipe 2 between the medicine mixing tank 1 and the medicine discharge pump 3 is also connected to an emptying pipe 13. When the medicine mixing tank 1 needs to be cleaned, the remaining medicine liquid in the tank can be emptied through the emptying pipe 13; an emptying control valve 14 is installed on the emptying pipe 13, which is mainly used to open and close the medicine liquid flow path in the emptying pipe 13.
[0041] Furthermore, the medicine discharging control valve 12 is installed between the medicine discharging pump 3 and the exhaust pipe 13 .
[0042] In addition, the control valves in the above embodiments 1 to 4 can be valves that can realize pipeline switching and flow control, such as ball valves, gate valves, etc. The specific model depends on actual needs.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
