Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a starch dewatering filter press. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to the material, causing the liquid to seep out. It is a commonly used solid-liquid separation device that was applied to chemical production in the early 18th century and is still widely used in industries such as chemical, pharmaceutical, metallurgy, dye, food, brewing, ceramics and environmental protection. In starch dewatering, it can uniformly remove water from starch.

[0003] Existing filter presses, such as the automatic chamber filter press disclosed in publication number CN215876377U, have advantages such as good filtration effect and high filter cloth disassembly and washing efficiency. However, when the filter plates are moved by the rear pull plate trolley, it is inconvenient to automatically push the filter material that is stuck on both sides of the filter plate to fall off due to its tight adhesion. Therefore, we propose a starch dewatering filter press. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A starch dewatering filter press includes: a filter press body and an auxiliary feeding assembly; the filter press body includes multiple sets of filter plates arranged inside it, filter cloth fixedly installed at the outer end of the filter plates, a motor fixedly installed on one side of the filter press body, a lead screw fixedly installed at the front end of the motor, and a pull plate trolley movably installed at the outer end of the lead screw; the auxiliary feeding assembly includes through holes arranged on the upper and lower sides inside the filter plates, elastic diaphragms fixedly installed at the outer ends of the through holes, air pipes fixedly installed in the through holes, an electric push rod fixedly installed at the outer end of the pull plate trolley, an external connecting pipe fixedly installed at the front end of the electric push rod, a connector fixedly installed inside the external connecting pipe, and an air pump fixedly installed at the outer end of the connector.

[0007] Preferably, air holes are provided on both sides of the trachea, and the air holes are located at the inner end of the through hole.

[0008] Preferably, a support plate is fixedly installed on both sides of the through hole.

[0009] Preferably, the upper end of the support plate is provided with multiple sets of circular holes.

[0010] Preferably, sealing rings are movably installed on both the upper and lower sides of the outer connecting pipe.

[0011] Preferably, mounting brackets are also fixedly installed on both sides of the filter plate.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] In this invention, an electric push rod installed at the outer end of the plate-pulling trolley in the filter press body can connect an external connecting pipe to the air pipes on both sides of the filter plate when the starch blocks on both sides of the filter plate are not falling off due to the plate-pulling trolley driving the filter plate to open and close. This allows air to be pumped into the through holes in the filter plate through an air pump, which inflates the elastic diaphragms on both sides of the through holes. The elastic diaphragms then bulge outward, conveniently pushing the starch blocks that have not fallen off the filter cloth outward, thus achieving the falling off of the starch blocks after they are pushed outward. This improves the ease of removing starch blocks after water removal from the filter press body. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of a starch dewatering filter press provided by this utility model.

[0026] Example 1:

[0027] Combination Figure 1-7 As shown, the present invention provides a starch dewatering filter press, comprising: a filter press body 100 and an auxiliary feeding assembly 200; the filter press body 100 includes multiple sets of filter plates 101 arranged therein, filter cloth 102 fixedly installed at the outer end of the filter plates 101, a motor 103 fixedly installed on one side therein, a lead screw 104 fixedly installed at the front end of the motor 103, and a pulling plate trolley 105 movably installed at the outer end of the lead screw 104, the pulling plate trolley 105 being bound and installed on the outside of the filter press body 100, and mounting brackets 106 fixedly installed on both sides of the filter plates 101; the auxiliary feeding assembly 200 includes through holes 201 arranged on the upper and lower sides inside the filter plates 101, and through holes 201 outside the filter plates 101. The device includes an elastic diaphragm 202 fixedly installed at both ends, an air tube 203 fixedly installed in the through hole 201, an electric push rod 204 fixedly installed at the outer end of the pull plate trolley 105, an external connecting pipe 205 fixedly installed at the front end of the electric push rod 204, a connector 206 fixedly installed inside the external connecting pipe 205, and an air pump 207 fixedly installed at the outer end of the connector 206. Air holes 208 are also provided on both sides of the air tube 203, and the air holes 208 are all located inside the through hole 201. Support plates 209 are also fixedly installed on both sides of the through hole 201. Multiple sets of round holes 210 are arranged on the upper end of the support plates 209. Sealing rings 211 are also movably installed on the upper and lower sides of the external connecting pipe 205.

[0028] Specifically, a filter press is a commonly used solid-liquid separation device. In starch dewatering, it can uniformly remove moisture from starch. The electric push rod 204 installed at the outer end of the pull plate trolley 105 in the filter press body 100 can connect the external connecting pipe 205 to the air pipes 203 on both sides of the filter plate 101 when the starch blocks on both sides of the filter plate 101 are not falling off due to the pull plate trolley 105 driving the filter plate 101 to open and close. This allows air to be pumped into the through holes 201 in the filter plate 101 by the air pump 207, inflating the elastic diaphragms 202 on both sides of the through holes 201. The elastic diaphragms 202 then bulge outwards, easily pushing the remaining starch blocks outside the filter cloth 102, thus improving the ease of removing starch blocks after dewatering. The external connecting pipe 204... The connector 206 on the inner side of the 5 is mainly for connecting the air pump 207 to realize the air blowing in the outer connecting pipe 205. The air holes 208 on both sides of the air pipe 203 are mainly used to realize the connection between the air pipe 203 and the through hole 201. The support plates 209 on both sides of the through hole 201 are mainly used to support the inner side of the elastic diaphragm 202, thereby avoiding the problem of the elastic diaphragm 202 being squeezed into the through hole 201 by the starch filtration water outside the filter cloth 102. The round holes 210 arranged in the support plate 209 are mainly for facilitating the connection between the inner end of the through hole 201 and the elastic diaphragm 202. The sealing rings 211 installed on the upper and lower sides of the outer connecting pipe 205 are mainly for ensuring the sealing between the connection when the electric push rod 204 drives the outer connecting pipe 205 to connect with the air pipe 203.

[0029] Working principle and usage process of this utility model:

[0030] After the filter plates 101 have completed filtration and been aerated for backflushing, the motor 103 on one side will drive the plate-pulling trolley 105 to move via the lead screw 104, thereby moving multiple sets of filter plates 101 within the filter press body 100 in sequence. As the plate-pulling trolley 105 moves the filter plates 101, the starch blocks on both sides after filtration will fall off under gravity, achieving automatic feeding. When there are firmly adhered starch blocks at the outer end of the filter plates 101, the electric push rod 204 and air pump 207 at the outer end of the plate-pulling trolley 105 are activated. After activation, the electric push rod 204 will drive the outer connecting pipe 205 to move inward. The air pipe 203 installed on the upper and lower sides of the outer end of the filter plate 101 is connected to the air pipe 203 via the external connecting pipe 205. The air pump 207 blows the air into the multiple sets of through holes 201 in the filter plate 101 through the external connecting pipe 205 and the air pipe 203. This causes the elastic diaphragms 202 on the outer side of the through holes 201 to bulge outward rapidly. This pushes the tightly adhered starch blocks outward instantly, and then pushes them off. This is to automatically push off the tightly adhered starch blocks that did not fall off automatically.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
