Description

Technical Field

[0001] This utility model relates to the field of filter press equipment, and in particular to a heated filter plate made of high thermal conductivity material. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device. It was applied to chemical production in the early 18th century and is still widely used in industries such as chemicals, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics, and environmental protection.

[0003] To further dry the filter cake after pressure filtration, current equipment generally uses electric heating. However, electric heating plates are prone to malfunctions, and damaged plates are not easy to repair, resulting in high production costs and unused waste heat. Summary of the Invention

[0004] To address the shortcomings of existing technologies, it is necessary to provide a filter plate heated by a material with high thermal conductivity, thereby reducing equipment costs and energy consumption.

[0005] This utility model relates to a heated filter plate made of high thermal conductivity material, comprising a plate frame, filter cloth, inlet, feeder, filtrate holes, and a heating zone located within the inner ring of the plate frame. The heating zone is formed by a plate frame, a bottom plate, and a cover plate sealing a water storage space. The bottom plate is flush with one side of the plate frame and is integrally molded from the same material to form a recessed area in the middle. The cover plate fits snugly over the recessed area to form the water storage space. An inlet and an outlet leading to the water storage space are respectively provided on the outer edge of the plate frame. Hot water enters through the inlet and flows out through the outlet.

[0006] Furthermore, the frame, base plate, and cover plate are all made of aluminum or aluminum alloy. Aluminum or aluminum alloy has fast thermal conductivity and low cost.

[0007] Furthermore, the plate frame, the bottom plate, and the cover plate enclose the water storage space, and the cover plate and the inner edge of the plate frame are connected to each other by laser welding, resistance welding, or bolts with a heat-resistant sealing ring to form a closed whole.

[0008] Furthermore, the base plate is provided with multiple evenly arranged transverse grates, one end of which is connected to the inner left edge of the plate frame, and the other end is provided with a longitudinal gap, that is, it maintains a gap with the inner right edge of the plate frame, so that water can flow through it; adjacent transverse grates are arranged in opposite directions, and the water flow gap is located at the other end of the transverse grates.

[0009] Furthermore, a number of evenly arranged longitudinal gratings are provided in the direction perpendicular to the transverse gratings. The longitudinal gratings are located between adjacent transverse gratings, and one end of the longitudinal gratings is provided with a transverse gap, that is, one end is connected to the inner edge of one of the transverse gratings or the plate frame, and the other end maintains a gap with the inner edge of another transverse grating or the plate frame. The gaps of adjacent transverse gratings are arranged in opposite directions.

[0010] Furthermore, after the cover plate is closed, all the longitudinal and transverse grates support the cover plate and are tightly connected to it, forming a water flow channel with the inlet and outlet pipes.

[0011] Furthermore, the water inlet is located at the lower edge of the plate frame, passes through the plate frame and enters the space enclosed by the bottom longitudinal and transverse diaphragms, from which water flows into the water storage space; the water outlet is located at the lower edge of the plate frame, passes through the plate frame and enters the space enclosed by the top longitudinal and transverse diaphragms, from which water flows into and out of the water storage space.

[0012] Furthermore, the feeder is inserted through the upper part of the base plate and the cover plate, and is fixed by the feeder base and the feeder cap on both sides of the heating plate by threads. The feeder base has a base side hole on its side. The filter cloths on both sides are respectively placed on the surface of the base plate and the cover plate and are inserted through the middle of the feeder and fixed.

[0013] Furthermore, the feed inlet is a through hole located at the upper end of the plate frame and perpendicular to it, and a feed tube is provided on its side to enter the feed hole in the feeder through the side hole of the base.

[0014] Furthermore, the feed inlet, feeder, and feed tube are all arranged symmetrically on the left and right sides.

[0024] To facilitate understanding of this utility model, it will be described below with reference to specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

[0025] like Figures 1 to 4 As shown, this utility model discloses a high thermal conductivity material heating filter plate, including a plate frame 1, filtrate holes 2, and a heating zone 4 located in the inner circle 3 of the plate frame. The heating zone 4 is sealed by the plate frame 1, a bottom plate 5, and a cover plate 6 to form a water storage space 7. The bottom plate 5 is flush with one side of the plate frame 1 and is integrally molded from the same material to form a central recessed area 8. The cover plate 6 fits snugly over the recessed area 8 to form the water storage space 7. An outlet 9 and an inlet 10 leading to the water storage space 7 are respectively provided on the outer edge of the plate frame 1. Hot water enters through the outlet 9 and flows out through the inlet 10.

[0026] In this example, the frame 1, the base plate 5, and the cover plate 6 are all made of aluminum or aluminum alloy.

[0027] See Figures 1 to 2 In this example, the cover plate 6 and the inner edge 11 of the plate frame are laser welded together to form a whole, and the water storage space 7 is formed by the plate frame 1, the bottom plate 5 and the cover plate 6.

[0028] See Figure 4 In the example, the base plate 5 is provided with multiple evenly arranged transverse grates 12, one end of which is connected to the inner left edge of the plate frame 1, and the other end is provided with a longitudinal gap 13, that is, it maintains a gap with the inner right edge of the plate frame, so that water can flow through it; adjacent transverse grates 12 are arranged in opposite directions, and the water flow gap is located at the other end of the transverse grates 12.

[0029] See Figure 4In the example, a number of evenly arranged longitudinal gratings 14 are provided in the direction perpendicular to the transverse gratings 12. The longitudinal gratings 14 are located between adjacent transverse gratings 12. One end of the longitudinal gratings 14 is provided with a transverse gap 15, that is, one end is connected to one of its transverse gratings 12 or the inner edge 11 of the plate frame, and the other end maintains a gap with another transverse grating 12 or the inner edge 11 of the plate frame. The gaps of adjacent transverse gaps 15 are arranged in opposite directions.

[0030] See Figure 4 In the example, after the cover plate 6 is closed, all longitudinal gratings 14 and transverse gratings 12 support the cover plate 6 and are tightly connected to it, forming a water flow channel with the water outlet 9 and the water outlet pipe.

[0031] See Figure 4 In this example, the outlet 9 is located at the lower edge of the plate frame 1, passes through the plate frame 1 and enters the space enclosed by the bottom longitudinal grating 14 and the transverse grating 12, from which water flows into the water storage space 7; the inlet 10 is located at the lower edge of the plate frame, passes through the plate frame 1 and enters the space enclosed by the top longitudinal grating 14 and the transverse grating 12, from which water flows in and out of the water storage space 7.

[0032] See Figures 1 to 6 In this example, the feeder 18 is installed on the upper end of the base plate 5 and the cover plate 6. It is fixed to the heating plate by the feeder base 19 and the feeder cap 22 on both sides by threads. The feeder base 19 has a base side hole 21 on its side. The filter cloths on both sides are respectively installed on the surface of the base plate 5 and the cover plate 6 and are installed in the middle of the feeder 18 and fixed.

[0033] See Figures 1 to 6 In this example, the feed port 16 is a through hole located at the upper end of the plate frame 1 and perpendicular to it, and a feed tube 17 is provided on its side to enter the feed hole 20 in the feeder 18 through the base side hole 21.

[0034] See Figures 1 to 6 In this example, the feed inlet 16, the feeder 18, and the feed pipe 17 are all arranged symmetrically on the left and right.

[0035] from Figure 4 As can be seen from the working principle of the high thermal conductivity material heating filter plate of this utility model, heated water is injected from the outlet 9 and enters the water storage space 7. It flows down layer by layer through the small space enclosed by the longitudinal grid 14 and the transverse grid 12, as well as the longitudinal gap 13 and the transverse gap 15. Finally, it flows out of the heating plate through the inlet 10. After external circulation and heat replenishment, it enters the water storage space 7 from the outlet 9. During the residence time of hot water entering and flowing out, the heating zone 4 exchanges heat with the adjacent filter cake that has been pressed and filtered, so as to dry it. In fact, the water storage space is equipped with several mutually perpendicular longitudinal grids and transverse grids to form a slow flow channel, so as to fully carry out heat exchange, make full use of energy, and have a low cost.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
