Description

Technical Field

[0001] This utility model relates to the field of filter plate processing technology for filter presses, and in particular to a heat-conducting composite filter plate with external feeding. Background Technology

[0002] A filter press is a device used for solid-liquid separation and is widely used in industries such as chemical, pharmaceutical, food, and environmental protection. It mainly consists of filter plates, filter frames, filter cloth, and hydraulic systems. Pressure is applied by the hydraulic system, causing solid particles to form a filter cake on the filter cloth, thereby achieving solid-liquid separation. During its operation, the filter plate is one of the more important components.

[0003] Current filter presses typically use center-feed filter plates. With this feeding method, as the number of filter plates increases, the pressure on the rear filter plates gradually increases during feeding. Excessive feeding pressure can cause the filter plates to deform and break. Furthermore, the requirements for filter cake dryness are becoming increasingly stringent in modern applications. Therefore, diaphragm filter presses are often chosen. The advantage of diaphragm filter presses is that they can perform secondary pressing. However, some materials have high viscosity or very fine solid particles that are difficult to filter, requiring the pressed cake to undergo secondary drying, which greatly increases energy consumption.

[0004] Therefore, this utility model provides a thermally conductive composite filter plate with external feeding to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to provide a thermally conductive composite filter plate with external feeding to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-conducting composite filter plate with external feeding, comprising a substrate for filtration, several raised cylinders fixedly connected to both sides of the substrate, a hot water inlet at the bottom of one side of the substrate, a hot water outlet at the top of the other side of the substrate, several support points bolted to the inner side of the substrate, water collection holes at the four corners of the substrate, liquid outlet holes at the inner side of the water collection holes, heat-conducting plates bolted to the upper and lower sides of the substrate, several filter beads fixedly connected to the surface of the heat-conducting plates, several circular holes of a number adapted to the support points at the inner side of the heat-conducting plates, the circular holes being located directly below the corresponding support points, a pressure frame bolted to the side of the heat-conducting plate away from the substrate, several screw holes at the outer side of the pressure frame, water collection holes at the four corners of the substrate and the pressure frame, the positions of the water collection holes at the outer side of the pressure frame corresponding to the positions of the water collection holes at the outer side of the substrate, several liquid outlet grooves at the outer side of the pressure frame, the liquid outlet grooves being fixedly connected to the corresponding liquid outlet holes.

[0007] In a preferred embodiment, a feeder is fixedly connected to the top of the substrate, and a feed hole is provided on the inner side of the feeder.

[0008] In a preferred embodiment, the raised cylinders are evenly distributed on the outer side of the substrate. The raised cylinders are used to support the heat-conducting plate. The raised cylinders are located between the substrate and the heat-conducting plate, and a hot water channel is formed between several raised cylinders. The hot water inlet and hot water outlet are fixedly connected to the outer side of the hot water channel.

[0009] In a preferred embodiment, a second sealing strip is fixedly connected to the outer side of the contact surface between the substrate and the heat-conducting plate, and a filter cloth is fixedly connected to the side of the filter bean away from the heat-conducting plate. The filter bean is located between the heat-conducting plate and the filter cloth and is evenly distributed, with a filtrate channel formed between several filter beans.

[0010] In a preferred embodiment, the outer side of the substrate is bolted with a plurality of locking bolts, and the pressure frame and the heat-conducting plate are connected to the outer side of the substrate by the locking bolts.

[0011] In a preferred embodiment, a No. 1 sealing strip and a No. 4 sealing strip are fixedly connected to the outer and inner sides of the contact surface between the substrate and the pressure frame, respectively.

[0012] In a preferred embodiment, a filter chamber is formed between the pressure frame and the heat-conducting plate, and a No. 3 sealing strip is fixedly connected to the contact surface between the substrate and the support point.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, by setting up a substrate, a pressure frame, a feeder, and a feed hole, allows materials to enter the filter chamber through the feeder. Since the feed channel is smaller than the feed hole, the materials continue to flow forward from the feed hole until they reach the last plate. Only then will the feed pump slowly increase the pressure, so that the pressure on the substrate increases with the amount of material entering, avoiding excessive pressure on the substrate, ensuring that the substrate can work normally, extending the working life of the device, and effectively saving the operating cost of the device.

[0015] This invention, by setting up a heat-conducting plate, filter beans, and a second sealing strip, allows hot water to be added between the base plate and the heat-conducting plate during operation. This heats the heat-conducting plate, causing the filter cake to heat up. Under high temperature, the moisture in the filter cake evaporates and vaporizes, thus reducing the moisture content of the filter cake. This allows the device to directly dry the filter cake without the need for an additional dryer, thereby saving a significant amount of energy, effectively reducing operating costs, and improving the practicality of the device.

Detailed Implementation

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-5 This utility model provides a heat-conducting composite filter plate with external feeding, including a base plate 1 for filtration. Several raised cylinders 7 are fixedly connected to both sides of the base plate 1, and the raised cylinders 7 are evenly distributed. A hot water inlet 14 is opened at the bottom end of one side of the base plate 1, and a hot water outlet 15 is opened at the top end of the other side of the base plate 1. Several support points 4 are bolted to the inner side of the base plate 1. Water collection holes 17 are opened at each of the four corners of the base plate 1, and liquid outlet holes 13 are opened inside the water collection holes 17. Heat-conducting plates 3 are bolted to the upper and lower sides of the base plate 1, and the surfaces of the heat-conducting plates 3 are fixed. A number of filter beans 6 are connected, and the filter beans 6 are circular. The inner side of the heat-conducting plate 3 has a number of circular holes that match the number of support points 4. The circular holes are located directly below the corresponding support points 4. The top of the substrate 1 is fixedly connected to a feeder 5. The inner side of the feeder 5 has a feed hole 16. The raised cylinders 7 are evenly distributed on the outer side of the substrate 1. The raised cylinders 7 are used to support the heat-conducting plate 3. The raised cylinders 7 are located between the substrate 1 and the heat-conducting plate 3, and a hot water channel is formed between the several raised cylinders 7. The hot water inlet 14 and the hot water outlet 15 are fixedly connected to the outer side of the hot water channel.

[0025] Please see Figures 1-5A pressure frame 2 is bolted to the side of the heat-conducting plate 3 away from the substrate 1. Several screw holes are opened on the outer side of the pressure frame 2. Water collection holes 17 are opened at the four corners of the substrate 1 and the pressure frame 2. The positions of the water collection holes 17 on the outer side of the pressure frame 2 correspond to the positions of the water collection holes 17 on the outer side of the substrate 1. Several liquid outlet grooves 18 are opened on the outer side of the pressure frame 2. The liquid outlet grooves 18 are fixedly connected to the corresponding liquid outlet holes 13. A second sealing strip 9 is fixedly connected to the outer side of the contact surface between the substrate 1 and the heat-conducting plate 3. The filter bean 6 is fixedly connected to the side away from the heat-conducting plate 3. There is a filter cloth, and filter beans 6 are located between the heat-conducting plate 3 and the filter cloth, and are evenly distributed. A filtrate channel is formed between several filter beans 6. Several locking bolts 12 are bolted to the outside of the base plate 1. The pressure frame 2 and the heat-conducting plate 3 are connected to the outside of the base plate 1 by locking bolts 12. A first sealing strip 8 and a fourth sealing strip 11 are fixedly connected to the outside and inside of the contact surface between the base plate 1 and the pressure frame 2, respectively. A filter chamber is formed between the pressure frame 2 and the heat-conducting plate 3. A third sealing strip 10 is fixedly connected to the contact surface between the base plate 1 and the support point 4.

[0026] The device is fixed to the filter press. The material enters the feed channel inside the feeder 5 and enters the filter chamber. At the same time, the filtrate flows through the filtrate channel between the filter beans 6 on the heat-conducting plate 3 and flows to the bottom of the heat-conducting plate 3. It flows from the two outlet holes 13 to the water collection hole 17. Since the feed channel is smaller than the feed hole 16, the material will continue to flow forward from the feed hole 16 until it reaches the last plate. The feed pump will then slowly pressurize. As the pressure increases, the material will enter the filter chamber sequentially from the feed channel. At this time, the pressure is still very small, so the pressure on the filter plate is also very small. When the material fills all the filter chambers, the filtrate will flow from the four outlet holes 13 to the water collection hole 17 at the same time, and then be discharged from the filter press. The feed pump continues to pressurize. At this time, all the filter plates are subjected to basically the same pressure, so the filter plates will not be damaged even if the pressure is high. This filter plate structure can extend the service life of the filter plates many times and effectively save operating costs.

[0027] While the material is flowing, hot water is added to the hot water inlet 14 at the lower right of the substrate 1 through external equipment. The hot water flows out from the hot water outlet 15 at the upper left corner. This cycle repeats, causing the temperature of the heat-conducting plate 3 to rise rapidly. The heat from the heat-conducting plate 3 is transferred to the filter cake. Since the diaphragm plate pressing also uses hot water pressing, the other side of the filter cake is also covered by high temperature. At this time, the vacuum system is turned on, and the moisture in the filter cake will evaporate and vaporize under the action of high temperature. The vaporized moisture is quickly sucked away, thereby reducing the moisture content of the mud cake. The mud cake filtered by this filter plate can achieve the effect of drying, thus eliminating the drying process, saving a lot of energy, and effectively reducing operating costs.

[0028] The working principle and usage process of this utility model are as follows: The device is fixed on a filter press. The material enters the feed channel inside the feeder 5 and then enters the filter chamber. At the same time, the filtrate flows through the filtrate channel between the filter beans 6 on the heat-conducting plate 3, flowing below the heat-conducting plate 3 and from the two liquid outlet holes 13 to the water collection hole 17. Since the feed channel is smaller than the feed hole 16, the material continues to flow forward from the feed hole 16 until it reaches the last plate. At this point, the feed pump slowly increases the pressure. As the pressure increases, the material enters the filter chamber sequentially from the feed channel. At this time, the pressure is still very low. Because the material is small, the pressure on the filter plate is also small. When all the filter chambers are full, the filtrate will flow from the four liquid outlets 13 to the water collection holes 17 and be discharged from the filter press. While the material is flowing, hot water is added to the hot water inlet 14 on the lower right of the substrate 1 through external equipment. The hot water flows out from the hot water outlet 15 in the upper left corner. This cycle repeats, which causes the temperature of the heat-conducting plate 3 to rise rapidly. The heat of the heat-conducting plate 3 is transferred to the filter cake, and the vacuum system is turned on. The moisture in the filter cake will evaporate and vaporize under the action of high temperature. The vaporized moisture is quickly drawn away, thereby reducing the moisture content of the filter cake.

[0029] The above-described vacuum system is existing technology disclosed in this utility model and will not be described in detail here.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
