Description

Technical Field

[0001] The present application relates to the technical field of wastewater filtration and treatment, and in particular to a wastewater treatment device for dry-process preparation of cuprous chloride and a treatment method thereof. Background Art

[0002] The main raw materials for preparing cuprous chloride by dry method include high-purity copper powder and chlorine gas. Under high temperature and appropriate pressure conditions, a chemical reaction occurs between the copper element and the chlorine gas to generate cuprous chloride solid. After cooling, the solvent and residual impurities are removed through filtering, washing and drying to obtain high-purity cuprous chloride solid.

[0003] Among them, a large amount of wastewater is generated in the process of washing cuprous chloride, which needs to be treated accordingly to meet the discharge standards before discharge. The wastewater contains a large amount of solid particle impurities that need to be treated separately from the wastewater. The most common method for solid-liquid separation is a filtering device, but the existing filtering device is very likely to cause clogging of the filter mesh as the filtered solid particles accumulate, which leads to poor wastewater treatment effect and low efficiency. In addition, as the solid particles on the filter mesh accumulate, their weight increases, which easily causes the filter mesh to be over-deformed and the filter holes on it to increase, so that some solid particles in the wastewater can pass through the filter holes and cannot be filtered out, and the stability and reliability are poor.

[0004] Therefore, there is an urgent need for a wastewater filtering device for cuprous chloride preparation to solve the problems existing in the above-mentioned existing filtering devices during actual use. Summary of the invention

[0005] The present application proposes a wastewater treatment device for the dry preparation of cuprous chloride and a treatment method thereof, which can timely clean the filtered solid particles, avoid the clogging of the filter mesh due to the large amount of solid particles gathering, and have the advantages of good filtering effect and high efficiency for solid particles, and is used to solve the problem that the existing filtering device is very likely to cause the clogging of the filter mesh as the filtered solid particles gather, thereby causing the effect of wastewater treatment to deteriorate and the efficiency to decrease, and as the solid particles on the filter mesh gather, their weight will increase accordingly, which is very likely to cause the filter mesh to be excessively deformed and cause the filter holes thereon to increase, so that some solid particles in the wastewater can pass through the filter holes and cannot be filtered out.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a wastewater treatment device for dry preparation of cuprous chloride, comprising an outer shell body with a bottom end fixedly mounted on a specific working area, a drainage pipe connected to the bottom of its inner cavity for discharging filtered wastewater is provided on one side of the bottom end of the outer shell body, and a normally closed dredging pipe connected to the bottom of its inner cavity is provided on one side of the bottom of the outer surface of the outer shell body, so that when necessary, the dredging pipe can be opened to clean the solid particles filtered out of the inner cavity of the outer shell body, an inner bracket is fixedly mounted on the bottom of the inner cavity of the outer shell body, and a plurality of groups of springs arranged in a circular array are provided on the periphery of the inner bracket, a filter screen for filtering is provided on the outer surface of the springs, and a shaft component is provided at the bottom of the inner cavity of the outer shell body, the bottom end of which extends to the bottom thereof and is transmission-connected to a driving motor fixedly mounted on the bottom end of the outer shell body, and the middle part of the outer surface of the shaft component is transmission-connected to the inner side surface of the springs through a connecting rod assembly.

[0007] Furthermore, the spring piece is initially configured as an inwardly concave arc-shaped curved surface structure, so that the outer surface of the filter screen is funnel-shaped, which can increase its effective filtering area and conform to the flow trend of the wastewater.

[0008] Furthermore, the shaft component includes a transmission shaft whose bottom end extends to the bottom of the outer shell and is fixedly connected to the output shaft of the driving motor. An eccentric sleeve is fixedly sleeved on the middle part of the outer surface of the transmission shaft, and a linkage sleeve is movably sleeved on the outer surface of the eccentric sleeve. When the eccentric sleeve rotates synchronously with the transmission shaft, the linkage sleeve is forced to rotate eccentrically, and under the transmission action of the connecting rod assembly, the filter is driven to expand outward or contract inward regularly.

[0009] Furthermore, the connecting rod assembly includes a first connecting rod pinned to the inner side surface of the spring sheet, the first connecting rod is movably connected to the inside of the second connecting rod, and the inner cavities of the first connecting rod and the second connecting rod are connected, and one end of the second connecting rod is pinned to the outer surface of the linkage sleeve. At the same time, a first pipeline connected to its inner cavity is provided on one side of the outer surface of the first connecting rod, and a second pipeline connected to its inner cavity is provided on one side of the outer surface of the second connecting rod, the other end of the second pipeline is connected to the pharmaceutical system, and a group of one-way flow valves are respectively provided on the first pipeline and the second pipeline.

[0010] Furthermore, several groups of the second pipelines are connected to the same drug delivery system or to different drug delivery systems according to actual use needs, so that the same drug or multiple different drugs can be sprayed on the filtered wastewater to meet actual use needs.

[0011] Furthermore, the top of the filter is always higher than the top of the outer shell, thereby preventing unfiltered wastewater from overflowing from the top of the filter and falling directly into the inner space of the filter due to excessive wastewater being transported.

[0012] A method for treating wastewater used in the dry preparation of cuprous chloride comprises the following steps:

[0013] S1. The wastewater is directed to the inner cavity of the outer shell and the outer space of the filter screen through the wastewater delivery system, and then the drive motor is started and the filter screen is driven to expand outward or contract inward regularly under the transmission action of the shaft component. At the same time, the drug delivery system is connected so that the inner cavity of the second pipeline is filled with drugs;

[0014] S2. During the process of the filter screen regularly expanding outward or contracting inward, the solid particles filtered by the outer side of the filter screen are shaken off and deposited at the bottom of the outer shell. Moreover, under the elastic action of the spring sheet, a certain resistance effect is exerted on the connecting rod assembly, and the first connecting rod and the second connecting rod are forced to move relative to each other.

[0015] S21, when the first connecting rod and the second connecting rod are stretched against each other, negative pressure is generated in the inner cavity of the first connecting rod, so as to draw the medicine from the second pipeline into the inner cavity of the first connecting rod;

[0016] S22, when the first connecting rod and the second connecting rod are pressed against each other, the agent in the first connecting rod is sprayed into the filtered wastewater through the first pipeline;

[0017] S3. Afterwards, the filtered wastewater located in the inner side space of the filter is discharged through the drainage pipe, and the solid particles settled at the bottom of the inner cavity of the shell and located in the outer side space of the filter are regularly cleaned by opening the dredging pipe.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present application provides a wastewater treatment device for the dry preparation of cuprous chloride and a treatment method thereof. The shaft component and the connecting rod assembly are arranged so that when the drive motor is started, the filter screen can be driven to expand outward or contract inward regularly under the transmission action of the shaft component and the connecting rod assembly, so as to vibrate and shake off the solid particles filtered on the filter screen, thereby preventing the filter holes on the filter screen from being blocked due to the large amount of filtered solid particles gathering. At the same time, the problem of the filter holes on the filter screen being blocked due to the large amount of solid particles gathering on the filter screen is effectively avoided, which causes the filter screen to be over-deformed and the filter holes to be enlarged, and causes some solid particles in the wastewater to pass through the filter holes and cannot be filtered out.

[0020] 2. The present application provides a wastewater treatment device for dry preparation of cuprous chloride and a treatment method thereof. Regarding the arrangement of the second connecting rod and the first pipeline on the connecting rod assembly, when the eccentric sleeve rotates eccentrically and drives the filter to regularly expand outward or contract inward, the elastic action of the spring sheet can produce a certain resistance effect on the connecting rod assembly and force the first connecting rod and the second connecting rod to move relative to each other. When the first connecting rod and the second connecting rod are stretched against each other, a negative pressure can be generated in the inner cavity of the first connecting rod to suck the agent from the second pipeline into the inner cavity of the first connecting rod. When the first connecting rod and the second connecting rod are squeezed against each other, the agent in the first connecting rod can be sprayed into the filtered wastewater via the first pipeline.

[0028] 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0030] At the same time, the problem that the accumulation of a large number of solid particles on the filter screen 6 causes its weight to increase, causing the filter screen 6 to deform excessively and causing the filter holes on it to increase, and causing some solid particles in the wastewater to pass through the filter holes and cannot be filtered out is effectively avoided.

[0031] like Figure 1 , Figure 2 As shown, in the present technical solution, the spring piece 5 is initially set to be an inwardly concave arc surface structure, so that the outer surface of the filter screen 6 is a funnel-shaped structure, which can increase its effective filtering area and conform to the flow trend of the wastewater.

[0032] like Figure 1 , Figure 4 As shown, in the present technical solution, the shaft component 7 includes a transmission shaft 10 whose bottom end extends to the bottom of the outer shell 1 and is fixedly connected to the output shaft of the driving motor 9. An eccentric sleeve 11 is fixedly sleeved in the middle of the outer surface of the transmission shaft 10, and a linkage sleeve 12 is movably sleeved on the outer surface of the eccentric sleeve 11. When the eccentric sleeve 11 rotates synchronously with the transmission shaft 10, the linkage sleeve 12 is forced to rotate eccentrically, and under the transmission action of the connecting rod assembly 8, the filter screen 6 is driven to expand outward or contract inward regularly.

[0033] like Figure 1 , Figure 4 as well as Figure 5As shown, in the present technical solution, the connecting rod assembly 8 includes a first connecting rod 13 pinned to the inner side of the spring sheet 5, the first connecting rod 13 is movably connected to the second connecting rod 14, and the inner cavities of the first connecting rod 13 and the second connecting rod 14 are connected, and one end of the second connecting rod 14 is pinned to the outer surface of the linkage sleeve 12, and at the same time, a first pipeline 15 connected to the inner cavity thereof is provided on one side of the outer surface of the first connecting rod 13, and a second pipeline 16 connected to the inner cavity thereof is provided on one side of the outer surface of the second connecting rod 14, the other end of the second pipeline 16 is connected to the pharmaceutical system, and a group of one-way flow valves are respectively provided on the first pipeline 15 and the second pipeline 16;

[0034] Furthermore, when the eccentric sleeve 11 rotates eccentrically and drives the filter screen 6 to expand outward or contract inward regularly, the elastic action of the spring sheet 5 can produce a certain resistance effect on the connecting rod assembly 8, and force the first connecting rod 13 and the second connecting rod 14 to move relative to each other. When the first connecting rod 13 and the second connecting rod 14 are stretched against each other, a negative pressure can be generated in the inner cavity of the first connecting rod 13 to suck the agent from the second pipeline 16 into the inner cavity of the first connecting rod 13. When the first connecting rod 13 and the second connecting rod 14 are squeezed against each other, the agent in the first connecting rod 13 can be sprayed into the filtered wastewater via the first pipeline 15.

[0035] like Figure 1 , Figure 5 As shown, in the present technical solution, several groups of second pipelines 16 are connected to the same drug delivery system or to different drug delivery systems according to actual use needs, so that the same drug or multiple different drugs can be sprayed into the filtered wastewater to meet actual use needs.

[0036] like Figure 1 As shown, in the present technical solution, the top of the filter screen 6 is always higher than the top of the outer shell 1 , thereby preventing unfiltered wastewater from overflowing from the top of the filter screen 6 and falling directly into the inner space of the filter screen 6 due to excessive wastewater being transported.

[0037] A method for treating wastewater used in the dry preparation of cuprous chloride comprises the following steps:

[0038] S1. The wastewater is directed to the inner cavity of the outer shell 1 and the outer space of the filter screen 6 through the wastewater delivery system, and then the drive motor 9 is started and the filter screen 6 is driven to expand outward or contract inward regularly under the transmission action of the shaft component 7. At the same time, the drug delivery system is connected so that the inner cavity of the second pipeline 16 is filled with drugs;

[0039] S2. During the process of the filter screen 6 regularly expanding outward or contracting inward, the solid particles filtered by the outer side of the filter screen 6 are shaken off and deposited at the bottom of the outer shell 1. Moreover, under the elastic action of the spring sheet 5, a certain resistance effect is generated on the connecting rod assembly 8, and the first connecting rod 13 and the second connecting rod 14 are forced to move relative to each other.

[0040] S21, when the first connecting rod 13 and the second connecting rod 14 are stretched against each other, negative pressure is generated in the inner cavity of the first connecting rod 13, so as to draw the medicine from the second pipeline 16 into the inner cavity of the first connecting rod 13;

[0041] S22, when the first connecting rod 13 and the second connecting rod 14 are pressed against each other, the agent in the first connecting rod 13 is sprayed into the filtered wastewater through the first pipeline 15;
