Description

Technical Field

[0001] The utility model relates to the technical field of washing and processing for preparing conductive silver powder, in particular to a filtering device for washing conductive silver powder, which can be directly arranged on the washing tank body of a stirring and washing device, and can directly carry out filtering operation on the materials of the next batch during the washing process, so as to shorten the process and improve the production efficiency. Background Art

[0002] Washing and processing is an indispensable process in the chemical liquid-phase reduction method for processing silver powder. After the silver powder slurry is filtered by a corresponding suction filtration device, it is put into a corresponding washing tank and stirred and washed with a washing liquid. Then, a surface modifier is added to the washed materials for dispersion treatment, and then the materials are pumped and discharged to a corresponding solid-liquid separation device for solid-liquid separation treatment. At present, the filtration and stirring washing of silver powder slurry are carried out separately, and a corresponding set of filtration equipment and a corresponding set of stirring and washing equipment need to be set up correspondingly. The overall processing cost is relatively high, and the overall process connection is time-consuming, resulting in relatively low washing efficiency of the materials.

[0003] Therefore, the research purpose of the utility model is to design a filtering device for washing conductive silver powder that can be directly arranged on the washing tank body of a stirring and washing device, and can directly carry out filtering operation on the materials to be washed in the next batch during the stirring and washing process, so as to effectively reduce the equipment cost and improve the process connection efficiency. Summary of the Invention

[0004] Aiming at the technical problems existing in the above-mentioned prior art, the utility model provides a filtering device for washing conductive silver powder, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0005] The technical solution of the utility model is as follows:

[0006] A filtering device for washing conductive silver powder, comprising:

[0007] A fixed container is fixedly connected to the outer side wall of the top of the corresponding washing tank body. A corresponding filter plate is fixedly connected to the inner side of the fixed container at intervals. The filter plate is evenly distributed with corresponding filter holes, and a corresponding filter cloth is fixedly connected to the inner side of the filter plate. An outlet pipe with the feed end connected to the bottom side of the fixed container is fixedly connected to the washing tank body in an inclined manner. An outlet valve is fixedly installed on the outlet pipe. A corresponding cover is detachably installed on the upper part of the fixed container, and a feed pipe equipped with a feed valve is connected outward to the cover;

[0008] The pressure filtration mechanism includes an air guide pipe connected to the cover on the inner side of the filter plate. A corresponding one-way valve is fixedly installed on the air guide pipe. A pressure filtration pipe communicating with the fixed container is fixedly connected inside the washing tank body above the discharge pipe. A corresponding pressure filtration piston is arranged inside the pressure filtration pipe. The pressure filtration piston is fixedly connected with a corresponding iron plate member outward through a corresponding connecting member;

[0009] The pressure filtration driving mechanism includes a stirring shaft rotatably arranged inside the washing tank body. The stirring shaft is driven by a corresponding driving motor. Push rods and pull rods corresponding to the positions of the iron plate members are fixedly connected at intervals on the upper part of the stirring shaft in a staggered manner. The length of the push rod is greater than that of the pull rod. Magnets are fixedly connected to the end parts of the pull rods respectively. When the push rod rotates past the iron plate member, it pushes the iron plate member outward. When the pull rod rotates past the iron plate member, the magnet adsorbs and drives the iron plate member inward.

[0010] The filtration device further includes a liquid discharge mechanism. The liquid discharge mechanism includes a liquid collection container connected to the bottom side of the fixed container in a communicating manner. A liquid discharge pipe equipped with a liquid discharge valve is connected outward at the bottom of the liquid collection container.

[0011] A suction filtration pipe is fixedly installed at the bottom side of the washing tank body. A corresponding filter element is fixedly installed at the liquid inlet end of the suction filtration pipe. The liquid outlet end of the suction filtration pipe is connected to a corresponding suction filtration pump.

[0012] A corresponding siphon tee is fixedly installed on the suction filtration pipe. The siphon section of the siphon tee is connected to the upper side of the fixed container through a corresponding negative pressure suction pipe.

[0013] The cover is fixedly connected to the fixed container by means of bolt locking.

[0014] A corresponding sealing gasket is fixedly arranged between the cover and the fixed container.

[0015] Advantages of the present utility model:

[0016] 1) By setting components such as a fixed container, a filter plate, and a filter cloth, the present utility model can be directly set on the washing tank body as a feeding mechanism. During the washing process of the materials in the washing tank body, as the stirring shaft rotates, the push rod and the pull rod continuously rotate through the position where the iron plate member is located. When the push rod rotates through the iron plate member, it pushes the iron plate member outwards to form a pressure filtration on the conductive silver powder slurry inside the filter cloth. The liquid in the conductive silver powder slurry is extruded out of the filter cloth and collected by the liquid collection container. When the pull rod rotates through the iron plate member, the magnet adsorbs and drives the iron plate member inwards. At this time, the one-way valve opens, and external air enters the inside of the filter cloth. In this way, during the washing process of the materials, the pressure filtration operation can be synchronously carried out on the materials to be washed in the next batch, thereby effectively reducing the equipment cost and improving the efficiency of process connection.

[0017] 2) The present utility model also fixedly installs a siphon three-way pipe on the suction filtration pipe, and connects the siphon section of the siphon three-way pipe to the upper side of the fixed container through a corresponding negative pressure suction pipe. During the process of suction filtering and discharging the washing liquid, a negative pressure can be formed on the fixed container through the siphon three-way pipe, thereby further carrying out the suction filtration operation on the materials to be washed in the next batch, significantly reducing the liquid content of the materials to be washed in the next batch, and effectively improving the practical effect of the present utility model.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] For the convenience of those skilled in the art to understand, the embodiments will now be further described in detail with reference to the drawings for the structure of the present utility model:

[0023] ReferenceFigures 1-3 , a filtering device for washing conductive silver powder, comprising:

[0024] A fixed container 1, fixedly connected to the outer side wall of the top of the corresponding washing tank body 2. A corresponding filter plate 3 is fixedly connected to the inner side of the fixed container 1 at intervals. Corresponding filter holes are evenly distributed on the filter plate 3, and a corresponding filter cloth 4 is fixedly connected to the inner side of the filter plate 3. An outlet pipe 5 with its feed end connected to the bottom side of the fixed container 1 is obliquely fixedly connected inside the washing tank body 1. A corresponding outlet valve 501 is fixedly installed on the outlet pipe 5. A corresponding cover 6 is detachably installed on the upper part of the fixed container 1. The cover 6 is externally connected to a feed pipe 7 equipped with a feed valve 701;

[0025] A pressure filtration mechanism 8, including an air guide pipe 801 connected to the cover 6 on the inner side of the filter plate 3. A corresponding one-way valve 802 is fixedly installed on the air guide pipe 801. A pressure filtration pipe 803 communicating with the inside of the fixed container 1 is fixedly connected inside the washing tank body 2 above the outlet pipe 5. A corresponding pressure filtration piston 804 is arranged inside the pressure filtration pipe 803. The pressure filtration piston 804 is externally fixedly connected to a corresponding iron plate member 806 through a corresponding connecting member 805;

[0026] A pressure filtration driving mechanism 9, including a stirring shaft 901 rotatably arranged inside the washing tank body 2. The stirring shaft 901 is driven by a corresponding driving motor 902. Push rods 903 and pull rods 904 corresponding to the position of the iron plate member 806 are fixedly connected to the upper part of the stirring shaft 901 at intervals and in a staggered manner. The length of the push rod 903 is greater than the length of the pull rod 904. Corresponding magnets 905 are fixedly connected to the end parts of the pull rods 904; when the push rod 903 rotates past the iron plate member 806, the iron plate member 806 is pushed outwards, and when the pull rod 904 rotates past the iron plate member 806, the magnet 905 adsorbs and drives the iron plate member 806 inwards.

[0027] The filtering device further includes a liquid discharge mechanism 10. The liquid discharge mechanism 10 includes a liquid collecting container 1001 connected to the bottom side of the fixed container 1 in a communicating manner. A liquid discharge pipe 1003 equipped with a liquid discharge valve 1002 is externally connected to the bottom of the liquid collecting container 1001.

[0028] Through the arrangement of components such as the fixed container 1, the filter plate 3, and the filter cloth 4, the present utility model can be directly set on the washing tank body 2 as a feeding mechanism. During the washing process of the materials in the washing tank body 2, as the stirring shaft 901 rotates, the push rod 903 and the pull rod 904 continuously rotate through the position of the iron plate member 806. When the push rod 903 rotates through the iron plate member 806, it pushes the iron plate member 806 outwards to perform pressure filtration on the conductive silver paste inside the filter cloth 4. The liquid in the conductive silver paste is extruded out of the filter cloth 4 and collected by the liquid collection container 1001. When the pull rod 904 rotates through the iron plate member 806, the magnet 905 adsorbs and drives the iron plate member 806 inwards. At this time, the one-way valve 802 opens, and external air enters the inside of the filter cloth 4. In this way, during the washing process of the materials, pressure filtration operation can be synchronously performed on the materials to be washed in the next batch, thereby effectively reducing the equipment cost and improving the efficiency of process connection.

A corresponding siphon three-way pipe 14 is fixedly installed on the suction filtration pipe 11, and the siphon section of the siphon three-way pipe 14 is connected to the upper side of the fixed container 1 through a corresponding negative pressure suction pipe 15.

[0030] During the process of suction filtration and discharge of the washing liquid, a negative pressure can be formed on the fixed container 1 through the siphon three-way pipe 14, so as to further perform suction filtration operation on the materials to be washed in the next batch, significantly reducing the liquid content of the materials to be washed in the next batch, and thus effectively improving the practical effect of the present utility model.

[0031] The cover 6 is fixedly connected to the fixed container 1 by means of bolt locking. A corresponding sealing gasket 16 is fixedly provided between the cover 6 and the fixed container 1.

[0032] The above is only the preferred embodiment of the present utility model.
