Detailed Description

It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.
Example 1: please refer to fig. 1-2;
the utility model provides the following technical scheme: an adenine produces the filter equipment, apply to the suspension of the activated carbon granule in the process of producing adenine of filtration, including the horizontally placed box 1; the left side of the upper surface of the box body 1 is inserted with a vertical liquid inlet pipe 11, and the right side of the upper surface of the box body is inserted with a vertical liquid outlet pipe 12; the lower end of the liquid inlet pipe 11 is close to the bottom of the box body 1; the lower end of the liquid outlet pipe 12 is close to the top of the box body 1; the upper end of the liquid inlet pipe 11 is connected with a coarse filtration device which is used for filtering coarse particles in the liquid medicine and inputting the filtered coarse particles into the box body 1; a plurality of filter plates 13 which are arranged at intervals along the horizontal direction are arranged in the box body 1; the periphery of each filter plate 13 is fixedly connected with the inner wall of the box body 1 in a sealing way; all the filter plates 13 are positioned between the liquid inlet pipe 11 and the liquid outlet pipe 12 and are used for filtering the liquid medicine flowing from the liquid inlet pipe 11 to the liquid outlet pipe 12; each filter plate 13 is inclined in such a direction that the upper end of the filter plate 13 is inclined toward the direction approaching the liquid inlet pipe 11.
It can be seen that the coarse filtration device filters larger size carbon particles, while the smaller size carbon particles are filtered in the housing 1.
The filtering principle in the box body 1 is that the filtering plates 13 divide the box body 1 into a plurality of independent cavities along the horizontal direction, the cavities where the liquid inlet pipes 11 are positioned are filled with liquid medicine, the liquid medicine is permeated to the cavities of the partition walls by utilizing water pressure, carbon particles in the liquid medicine are filtered in the process, and the effect of separating the carbon particles is achieved through the filtering effect of the filtering plates 13. At the same time, the carbon particles attached to the filter plate 13 naturally fall under the action of gravity, so that the risk of blocking the filter plate 13 is reduced. In addition, suspended char particles in each of the chambers may also naturally settle to act as a stationary separator. Therefore, the box body 1 can be kept still and filtered, and has the functions of automatic cleaning and blockage prevention.
In order to further improve the filtering effect, the meshes of the plurality of filter plates 13 are sequentially reduced along the direction from the liquid inlet pipe 11 to the liquid outlet pipe 12.
Illustratively, the number of filter plates 13 within the cabinet 1 is at least three. The mesh sizes of the three filter plates 13 are sequentially 50 meshes, 100 meshes and 200 meshes.
In order to reduce the filtering load in the case 1, the chemical solution is first subjected to rough filtration by a rough filtration device. The rough filtering device comprises a rough filtering box 2; a pair of partition plates 21 are provided in the straining box 2 to divide the straining box 2 into a filtering chamber 22 located in the middle and a collecting chamber 23 located at the left and right sides of the filtering chamber 22; the upper end of the filtering chamber 22 is connected with a feed port 24 for receiving the liquid medicine to be filtered; in the filtering chamber 22, a plurality of filtering boxes 25 are fixedly arranged on the partition plate 21 at intervals, each filtering box 25 is internally provided with a hollow cavity, the hollow cavity is communicated with the collecting chamber 23, and a filtering layer is arranged on the surface of the hollow cavity and is used for filtering the liquid medicine flowing from the filtering chamber 22 to the collecting chamber 23; each of the collection chambers 23 is connected with a discharge pipe 26; the ends of the two discharging pipes 26 are communicated with the liquid inlet pipe 11, and are used for conveying the liquid medicine filtered by the filter box 25 to the box body 1.
The operation principle of the rough filtration device is that the liquid medicine is conveyed to the filtration chamber 22 by the feed inlet 24, and is permeated into the cavity in the filtration box 25 by utilizing the principle of hydraulic permeation, and carbon particles in the liquid medicine are filtered in the process. The liquid medicine passing through the filter cartridge 25 flows to the collecting chamber 23 and is discharged through the discharge pipe 26. Wherein, a plurality of spaced filter cartridges 25 have substantially increased filtration area, have greatly improved filtration efficiency compared to a single layer filter screen. At the same time, the carbon particles suspended in the filter chamber 22 may still settle. Therefore, the filter chamber 22 also has the effects of standing and filtering, and the filtering efficiency is improved.
In order to reduce the risk of clogging of the filter cartridges 25, each of said filter cartridges 25 is arranged vertically, and solid particles for accumulating on the side walls of said filter cartridges 25 can naturally slide down. The filter chamber 22 thus far also has an automatic cleaning, anti-clogging effect.
In order to facilitate the cleaning of the filtered carbon particles, a discharge pipe 27 is provided at the bottom of the filter chamber 22 for discharging the particles accumulated in the filter chamber 22; the discharge pipe 27 is provided with a stop valve 28 for controlling the communication or closing of the discharge pipe 27. The shut-off valve 28 is normally closed, and after the filtration operation is completed, the liquid in the rough filtration tank 2 is drained, and the shut-off valve 28 is opened, whereby the filter residue accumulated in the bottom of the filtration chamber 22 is discharged.
In order to further improve the rough filtering effect, the tail ends of the two discharging pipes 26 are communicated with one end of the collecting pipe 3, and the other end of the collecting pipe 3 is communicated with a three-way pipe 31; one of the outlet ends of the three-way pipe 31 is communicated with the liquid inlet pipe 11 and is used for conveying the liquid medicine filtered by the filter box 25 to the box body 1; the other outlet end of the tee pipe 31 is communicated with a circulating pump 32, the outlet end of the circulating pump 32 is communicated with a return pipe 33, and the other end of the return pipe 33 is communicated with the feed inlet 24; the liquid inlet pipe 11 is provided with a control valve 34 for controlling the communication or closing of the liquid inlet pipe 11. It can be seen that when the control valve 34 is closed, the circulation pump 32 is started, and the rough filtration device forms a circulation filtration system to drive the liquid medicine to circulate through the filtration box 25, so as to achieve the effect of multiple filtration, further filter out carbon particles, and reduce the filtration burden of the downstream box 1. Then, the circulation pump 32 is closed, the control valve 34 is opened, and the filtered chemical liquid is output to the tank 1, thereby performing finer filtration. Thereby further reducing the burden on the filter plate 13 and further reducing the risk of the filter plate 13 being blocked.
In use, the liquid medicine to be filtered enters the filter chamber 22, flows through the filter box 25, enters the collection chamber 23, and flows to the tee 31. In both modes of operation, the first is to start the circulation pump 32 after the control valve 34 is closed and start the coarse filtration circulation filtration system. After multiple rough filtration, the carbon particles in the liquid medicine are greatly reduced. Then, the second operation mode is started, the circulation pump 32 is turned off, the control valve 34 is opened, and the filtered liquid medicine is output to the tank 1. The liquid medicine is filled in the chambers formed by dividing the filter plates 13 in sequence, and is filtered after penetrating the filter plates 13 in sequence. Finally, the liquid medicine with highest cleanliness at the uppermost end is pumped by the top liquid outlet pipe 12 of the box body 1 which is close to the box body, so that the product quality of the liquid medicine is improved.
The advantages of this embodiment are:
(1) The rough filtration box 2 is a rough filtration mechanism, the box body 1 is a fine filtration mechanism, rough filtration and fine filtration are performed, the two-stage filtration is performed, the efficiency is improved, and the risk of blocking a filter component is reduced.
(2) The two-stage filtering systems of rough filtration and fine filtration are provided with standing and filtering at the same time, and have the functions of automatic cleaning and blockage prevention; the risk of clogging of the filter element is further reduced while the filter efficiency is improved.
(3) Dynamic filtration, long standing time caused by simply relying on standing action is avoided, and production efficiency is greatly improved.
In a word, the device adopts a dynamic filtering mode, and is capable of standing and filtering at the same time, and has the effects of automatic cleaning and blocking prevention, so that the production efficiency is accelerated; the problems of long time consumption and low production efficiency caused by a static separation mode are avoided.
