Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, and in particular to a high-pressure double-diaphragm plate-frame drying integrated machine. Background Art

[0002] In the social production process, many types of sludge are produced, such as municipal sludge, catering wastewater and oilfield sludge. With the development of society, people pay more and more attention to the treatment of sludge. Nowadays, there are scientific treatment methods. Generally, sewage is passed into a storage tank, then stirred with drugs, and then processed through feed filtration, high-pressure double-diaphragm pressing and filtration dehydration, and low-temperature vacuum dehumidification and drying. The moisture in the filter cake is fully removed, and the sludge is deeply reduced and harmlessly treated, thereby achieving the effect of solid-liquid separation of sludge in the suspension, minimizing the moisture in the sludge, and forming a mud cake.

[0003] In the existing patent 202223102179.0, an integrated machine with a high-pressure double-diaphragm low-temperature drying function is disclosed, including a main frame, a cylinder seat is fixedly installed on one side of the top of the main frame, a thrust plate is fixedly installed on the other side of the top of the main frame, a filter plate pressing cylinder is fixedly installed in the middle of the cylinder seat, and ninety-nine double-diaphragm filter press plate mechanisms are installed inside the main frame, and the ninety-nine double-diaphragm filter press plate mechanisms are evenly divided into three groups. The utility model replaces the traditional filter cake filtration by arranging a double-diaphragm filter press plate mechanism. The sludge is filtered through the double-diaphragm filter plate and the filter cloth, thereby shortening the sludge filtration time. After the filtration is completed, the water content of the material is low, thereby reducing the subsequent drying cost; when the filter press is cleaned, the filter cloth lifting and driving cylinder is pushed from the bottom of the track to adjust the height of the filter cloth on the double-diaphragm filter press plate mechanism. During the up and down movement of the filter cloth, the high-pressure nozzle pipe sprays cleaning water to clean the filter cloth, saving time and effort.

[0004] In the above structure, the mud cake can be dried, but since the equipment needs to filter the mud cake during operation, a force will be applied to the mud cake. After the mud cake is formed, part of the mud cake will adhere without being acted upon by external force, making it difficult for the mud cake to automatically fall off the equipment, which can cause equipment jamming. For example, if the equipment is shut down to operate and the mud cake is shoveled off with tools, it will be difficult for the equipment to work continuously, reducing the equipment's efficiency in treating sludge, which is not conducive to the equipment's automatic treatment of mud cake, reducing work efficiency, and increasing the company's production costs.

A circulating heating assembly 7 connected to the diaphragm assembly 3 and the cleaning assembly 6 is provided on the support frame 1, and the circulating heating assembly 7 heats the mud cake to dry the mud cake;

[0037] The pulling mechanism 5 is provided with a transmission assembly 8, and the transmission assembly 8 is provided with a pushing assembly 9, which is located inside the diaphragm assembly 3 and the plate frame assembly 4. When the pulling mechanism 5 moves, the diaphragm assembly 3 and the plate frame assembly 4 are separated, and the pushing assembly 9 pushes the mud cake in the accommodating space to fall;

[0038] A feeding pipe 10 for introducing sludge is arranged on the pressing mechanism 2, and the feeding pipe 10 is communicated with each accommodating space.

[0039] Working principle: When treating sludge, start the pressing mechanism 2, and use the pressing mechanism 2 to push the diaphragm assembly 3 and the plate-frame assembly 4 to move until the diaphragm assembly 3 and the plate-frame assembly 4 are in close contact to form a seal, and the diaphragm assembly 3 and the plate-frame assembly 4 are arranged alternately, and the sludge is passed into the feed pipe 10 by the equipment. Under the action of pressure, the sludge fills the accommodating space of the diaphragm assembly 3 and the plate-frame assembly 4 to form a mud cake with high water content, and the mud cake is cleaned. The mud cake in each accommodating space is cleaned by the cleaning assembly 6, and then the water is discharged. The circulating heating assembly 7 is used to pass hot water into the diaphragm assembly 3, forcing the diaphragm assembly 3 to expand, thereby squeezing and compressing the mud cake in the accommodating space, forcing the water to be discharged. Due to the introduction of hot water, the temperature of the mud cake in the accommodating space increases, and the hot water is continuously circulated and input, forcing the accommodating space to continuously generate water vapor and continuously discharge it until the moisture in the mud cake is dried to a reasonable content; when the moisture content of the mud cake drops to an ideal level, the mud cake needs to be cleaned.

When pulling, the transmission assembly 8 is forced to act, and the transmission assembly 8 drives the pushing assembly 9 to act, and the pushing assembly 9 pushes the mud cakes on the diaphragm assembly 3 and the plate-frame assembly 4, forcing the mud cakes to loosen and fall smoothly. In summary, the high-pressure double-diaphragm plate-frame drying integrated machine of the present application cyclically heats the mud cake to dry it, thereby reducing the moisture content of the mud cake. When unloading the mud cake, the diaphragm assembly 3 and the plate-frame assembly 4 are pulled in sequence, forcing the mud cake to loosen and separate from the diaphragm assembly 3 and the plate-frame assembly 4, so that when the diaphragm assembly 3 and the plate-frame assembly 4 are separated, the mud cake falls smoothly, avoiding the phenomenon of mud cake adhesion caused by extrusion, forcing the mud cake to fall off automatically, reducing the jamming phenomenon of the equipment, making the equipment work continuously, improving the equipment's sludge treatment efficiency, and facilitating the automatic processing of mud cake separation by the equipment, improving the drying efficiency, and reducing the production cost of the enterprise.

[0048] like Figure 1 , Figure 8 and Fig.10 As shown, the high-pressure double-diaphragm plate and frame drying machine of the present invention, the transmission assembly 8 includes a support plate 801 arranged on the support frame 1, a cylinder 802 is arranged on the support plate 801, a piston 803 is arranged in the cylinder 802, a pull rod 804 is arranged on the piston 803, the pull rod 804 passes through the cylinder 802, and a connecting plate 805 connected to the pull rod 804 is arranged on the support block 501.

[0049] like Figure 1 , Figure 8 and Fig. 9 As shown, in the high-pressure double-diaphragm plate-frame drying machine of the present invention, the pushing component 9 includes a conduit 901 arranged on the cylinder 1 802, and the frame 1 301 and the frame 2 401 are both provided with a T-shaped cylinder 2 902, and pistons 2 903 are provided at both ends of the cylinder 2 902, and a pushing rod 904 is provided on the piston 2 903, and the pushing rod 904 passes through the cylinder 2 902, and a pushing plate 905 is provided on the pushing rod 904, wherein, when the pushing plate 905 is located inside the frame 1 301, the pushing plate 905 is located between the two rubber diaphragms 302, and a plurality of through holes 906 are opened on the pushing plate 905; when the pushing plate 905 is located outside the frame 2 401, the pushing plate 905 is tightly fitted on the surface of the frame 2 401, and the pushing rod 904 passes through the frame 2 401.

[0050] Working principle: When the sludge is processed, the hydraulic push rod 201 is started, and the output end of the hydraulic push rod 201 drives the pressing plate 202 to move, and under the action of the support block 501 and the slider 502, the frame 1 301 and the frame 2 401 are forced to squeeze each other until the frame 1 301 and the frame 2 401 form a seal;

[0051] The device is connected with the feed pipe 10 so that the sludge is continuously introduced into the feed pipe 10, and the sludge is introduced into each accommodation space through the feed pipe 10. When the sludge passes through the frame 1 301, the sludge passes through the pipe 1 303. When the sludge passes through the frame 2 401, the sludge passes through the pipe 2 402, so that each accommodation space is continuously filled with sludge until each accommodation space is full of sludge; the filter cloth 304 filters the sludge, and the wastewater enters the drainage head 608. The wastewater of the drainage head 608 is continuously introduced into the drainage pipe 607, and the wastewater is discharged out of the device through the hose 2 609. At this time, the moisture content of the mud cake is relatively high;

[0052] Before squeezing the mud cake, the mud cake is cleaned, the water supply pipe 602 is connected to the water source, the booster pump 1 603 is started, and the water in the water tank 601 is introduced to the water distribution pipe 605 through the action of the hose 1 604, and the water is introduced into the water outlet head 606 through the water distribution pipe 605. Since the water outlet head 606 is connected with the accommodating space, the water is forced to wash the mud cake in the accommodating space through the water outlet head 606, thereby improving the quality of the mud cake; when discharging wastewater, the wastewater enters the drain pipe 607 through the drain head 608, and the wastewater is discharged out of the equipment through the hose 2 609, thereby achieving the effect of discharging wastewater;

[0053] When the mud cake is extruded and heated, the booster pump 2 701 is started, forcing the booster pump 2 701 to guide the water in the water tank 601 into the output pipe 703, and then into the hose 3 705 through the circulation box 704. The water temperature is increased by the heat exchange of the heat exchanger 706, and the hot water is guided into the circulation pipe 707. Since the circulation pipe 707 is connected to the inside of the frame 1 301, the hot water is forced to enter the frame 1 301. The amount of hot water in each frame 1 301 increases, forcing the hot water to squeeze the rubber diaphragm 302, causing the rubber diaphragm 302 to expand, thereby squeezing the mud cake, causing the water in the mud cake to enter. The temperature of the mud cake increases, and the water in the mud cake generates water vapor. The waste water and water vapor are discharged from the equipment through the hose 2 609, the drain head 608 and the drain pipe 607, so that the water content of the mud cake gradually decreases. When the hot water is replaced, the booster pump 2 701 is stopped, and the booster pump 3 702 is started. The booster pump 3 702 guides the hot water in the frame 1 301 into the water tank 601 through the circulation pipe 707, the hose 3 705 and the circulation box 704. The booster pump 2 701 is started again, and the booster pump 3 702 is stopped, so that the circulation of hot water can be realized.

[0054] When the moisture content of the mud cake is reduced to an ideal level, the mud cake needs to be unloaded, and the hydraulic push rod 201 is started in the reverse direction. The output end of the hydraulic push rod 201 drives the pressing plate 202 to move backward. Under the action of the support block 501 and the slider 502, the pressure between the frame 1 301 and the frame 2 401 disappears.

[0055] The moving vehicle body is started, and the moving vehicle body moves to a reasonable position, and the elastic hook piece 504 moves with it. When the elastic hook piece 504 moves to the support block 501, the elastic hook piece 504 is compressed under the action of pressure resistance until the elastic hook piece 504 moves from one end of the support block 501 to the other end of the support block 501, and the elastic hook piece 504 is restored. At this time, the moving vehicle body moves in the opposite direction. Since there is no pressure between the frame 1 301 and the frame 2 401, the elastic hook piece 504 drives the support block 501 to move and separate from the frame 1 301 or the frame 2 401, so that the mud cake falls off freely.

[0056] When the moving body drives the frame 1 301 to move, the frame 1 301 drives the pulling rod 804 and the connecting plate 805 to move synchronously, so that the pulling rod 804 pushes the piston 1 803 to move, and the piston 1 803 squeezes the gas in the cylinder 1 802, so that the gas enters the cylinder 2 902 in the next frame 2 401 through the conduit 901, and the gas volume in the cylinder 2 902 decreases and the pressure increases, forcing the gas to drive the piston 2 903 to move, so that the piston 2 903 drives the push rod 904 to move, and the push rod 904 drives the push plate 905 to move, so that the push plate 905 pushes out the mud cake, so that the mud cake leaves the frame 2 401; similarly, when the moving body drives the frame 2 401 to move, the frame 2 401 drives the pulling rod 804 and the connecting plate 805 to move synchronously, so that the pulling rod 804 drives the piston 1 803 to move, The piston 1 803 squeezes the gas in the cylinder 1 802, so that the gas enters the cylinder 2 902 in the next frame 1 301 through the conduit 901. The volume of the gas in the cylinder 2 902 decreases and the pressure increases, forcing the gas to drive the piston 2 903 to move, so that the piston 2 903 drives the push rod 904 to move, and the push rod 904 drives the push plate 905 to move, so that the push plate 905 drives the rubber diaphragm 302 to move, so that the rubber diaphragm 302 pushes out the mud cake, so that the mud cake is separated from the frame 1 301, so that the frame 1 301 and the frame 2 401 alternately push out the mud cake, so that the frame 1 301 moves, exposing the frame 2 401, so that the frame 2 401 pushes out the mud cake, making it difficult for the mud cake to adhere, and according to the above steps, the mud cake between the frame 1 301 and the frame 2 401 is separated in sequence and falls off smoothly;

[0057] The setting of the pressing mechanism 2 provides a pressing power, so that the frame 1 301 and the frame 2 401 move along the support frame 1, so as to press the frame 1 301 and the frame 2 401 tightly, so that the frame 1 301 and the frame 2 401 form a seal, and when retreating, the frame 1 301 and the frame 2 401 are separated, so that the mud cake falls off from the accommodating space; the setting of the diaphragm assembly 3 and the plate-frame assembly 4 forms a filter chamber, so that the mud cake is filtered between the frame 1 301 and the frame 2 401, so that the moisture of the mud cake is reduced, and the rubber diaphragm 302 can expand, so that the rubber diaphragm 30 2 squeezes the mud cake to further reduce the moisture content, and the filter cloth 304 can filter out the moisture so that the mud cake cannot pass through. The alternating arrangement of the frame 1 301 and the frame 2 401 forms a filter press device, and the diaphragm assembly 3 and the plate-frame assembly 4 cooperate with each other; the setting of the pulling mechanism 5 can drive the frame 1 301 and the frame 2 401 to move without pressure, so that the frame 1 301 and the frame 2 401 are pulled in turn, thereby exposing the mud cake between the frame 1 301 and the frame 2 401; the setting of the cleaning assembly 6 can clean the mud cake to achieve mud cake cleaning The cleaning effect can clean the harmful substances in the mud cake, make the mud cake more stable, reduce the content of pollutants in the mud cake, improve the quality of the mud cake, and discharge the waste water out of the equipment; the setting of the circulating heating component 7 can heat the water and pass it into the frame 301, so that the rubber diaphragm 302 expands, thereby squeezing the water in the mud cake, and the hot water transfers the temperature to the mud cake, so that the water in the mud cake evaporates, and the hot water in the frame 301 can be replaced to achieve the effect of circulating hot water replenishment; the setting of the transmission component 8 can obtain the force of the moving vehicle body, so that the transmission component 8 can be replaced by the hot water in the frame 301. The moving component 8 performs reasonable actions, thereby transmitting the force to the pushing component 9. When the frame 1 301 and the frame 2 401 are separated in cooperation with the pushing component 9, the mud cake can fall off, reducing the phenomenon of mud cake adhesion; the setting of the pushing component 9 can push out the mud cake in the accommodating space at the frame 1 301 and the frame 2 401, so that the mud cake falls off smoothly, avoids the phenomenon of mud cake adhesion caused by squeezing, forces the mud cake to fall off automatically, reduces the jamming of the equipment, makes the equipment work continuously, improves the equipment's efficiency in treating sludge, and is conducive to the equipment's automatic treatment of mud cake separation.
