Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0030] like Figures 1 to 6 As shown, the present invention provides an intelligent multi-adsorption vacuum disc filter, comprising:
[0031] A tank body 9, a main shaft 1 is rotatably connected to the top of the tank body 9, a filter plate 6 is arranged on the outside of the main shaft 1, and a filter cloth is arranged on the outside of the filter plate 6;
[0032] The distribution head 5 and the distribution disk are connected and arranged at the end of the main shaft 1. The distribution disk cooperates with the rotating disk on the main shaft 1. The rotating disk is evenly distributed with multiple through holes along the circumferential direction. The distribution head 5 is sequentially provided with a suction area 18, a dehydration area 19, a secondary pressurization area 20, a discharge area 21 and a backwashing area 22 in the clockwise direction along the circumference. The distribution disk is provided with a suction groove 24, a dehydration groove 23, a secondary pressurization groove 25, a discharge groove 26 and a backwashing groove 27 which are connected with the suction area 18, the dehydration area 19, the secondary pressurization area 20, the discharge area 21 and the backwashing area 22 respectively along the circumferential direction;
[0033] The first pipeline, the second pipeline, the third pipeline, the fourth pipeline and the fifth pipeline are respectively connected to the suction area 18, the dehydration area 19, the secondary pressurization area 20, the unloading area 21 and the backwashing area 22, the first pipeline and the third pipeline are connected to the suction vacuum pump, the first pipeline and the third pipeline are respectively provided with a regulating valve and a solenoid valve, the second pipeline is connected to the dehydration vacuum pump, the fourth pipeline is connected to the fan, and the fifth pipeline is connected to the backwashing component;
[0034] The control unit is connected with the solenoid valve, and the control unit is used to control the intermittent opening and closing of the solenoid valve.
[0035] Specifically, in order to solve the problem that the traditional intelligent multi-adsorption vacuum disc filter has poor dehydration effect when dehydrating fine materials and wastes excess vacuum air volume in the suction area 18; the distribution head 5 and distribution disc of the vacuum disc filter provided by the present invention are respectively provided with a suction area 18, a dehydration area 19, a secondary pressurization area 20, a discharge area 21, a backwashing area 22 and a suction groove 24, a dehydration groove 23, a secondary pressurization groove 25, a discharge groove 26 and a backwashing groove 27 in a circumferential clockwise direction, and a secondary pressurization area 20 is added after the suction area 18 and the dehydration area 19. The secondary pressurization area 20 is connected to the suction vacuum pump together with the first pipeline connected to the suction area 18 through a third pipeline, which can make good use of the excess vacuum air in the suction area 18 The amount of vacuum air in the suction zone 18 can be avoided from being lost. Meanwhile, the secondary pressurization zone 20 utilizes the excess vacuum air in the suction zone 18 to re-adsorb and dehydrate the filter cake formed by the fine material after the de-drying zone 19, which can improve the dehydration effect of the fine material and reduce its moisture content. The solenoid valve on the third pipeline is intermittently opened and closed under the control of the control unit, which does not continuously affect the vacuum degree of the suction zone 18, and can also utilize this intermittent adsorption effect to improve the dehydration effect of the fine material, so that the moisture content of the fine material is further reduced. After passing through the secondary pressurization zone 20, the positive pressure of the fan is used to make the filter cake fall off the filter cloth, and then the filter cloth is washed by the backwashing component when passing through the backwashing zone 22, so as to realize the function of cleaning the filter cloth and extend its service life.
[0036] Furthermore, the dehydration zone 19 uses an independent dehydration vacuum pump to provide vacuum air volume to maintain a stable dehydration effect. Compared with the traditional vacuum disc filter, the dehydration effect of the dehydration zone 19 remains unchanged.
[0037] In this embodiment, if Figure 1 and Figure 3 As shown, a plurality of filter plates 6 are evenly spaced along the axial direction of the main shaft 1 .
[0038] Optionally, bearing seats 2 and bearing bushes are provided on the upper sides of both ends of the tank body 9, the main shaft 1 is connected to the bearing bushes, and the main shaft 1 includes a filtrate tube, which is connected to the filter plate 6 and the through hole.
[0039] Specifically, bearing seats 2 and bearing shells are provided at both ends of the trough body 9, the main shaft 1 is supported between the two bearing seats 2, the filter plate 6 is arranged on the filtrate tube, and the filter plate 6 socket is clamped and fixed on the main shaft 1 through the filter fan pull rod 4, the filter fan pressure block 14 and the filter fan clamping nut 3.
[0040] Optionally, the suction vacuum pump is connected to the first pipeline and the third pipeline through a suction and liquid discharge tank.
[0041] Specifically, the first pipeline and the third pipeline are both connected to the suction and discharge tank, and the suction and discharge tank is evacuated by the suction vacuum pump. The regulating valve on the first pipeline can adjust the opening, and then adjust the vacuum volume of the suction area 18 to adapt to different material working conditions. The solenoid valve on the third pipeline can adopt a normally closed solenoid valve, and the control unit can control it according to the timing module. It can set a uniform opening time and interval time, and can also flexibly control its opening and closing according to needs.
[0042] Optionally, the suction area 18 or the suction channel 24 is provided with a vacuum gauge, and the control unit is used to control the opening and closing frequency of the solenoid valve according to the detection result of the vacuum gauge.
[0043] Specifically, the vacuum gauge can detect the vacuum air pressure in the suction area 18. The air pressure threshold of the suction area 18 can be set in the control unit, and the vacuum air pressure is compared with the air pressure threshold of the suction area 18. When the vacuum air pressure is higher than the air pressure threshold of the suction area 18, the opening time of the solenoid valve is increased or the opening interval of the solenoid valve is shortened, so that the vacuum air volume in the suction area 18 is not excessively redundant, thereby avoiding excessive material adsorbed by the suction area 18 and causing the filter cake to be too thick.
[0044] Optionally, a transmission gear 7 is provided at one end of the main shaft 1 , and a main shaft driving mechanism 12 is provided on the outer side of one end of the slot body 9 , and the main shaft driving mechanism 12 is in transmission cooperation with the transmission gear 7 .
[0045] Specifically, the main shaft driving mechanism 12 may adopt a structure in which a driving motor is connected to a driving gear, and the main shaft 1 is driven to rotate by meshing the driving gear with the transmission gear 7 .
[0046] Optionally, the distribution head 5 and the distribution disk are arranged at the outer end of the main shaft 1, and a compression spring 8 is arranged on the outer side of the distribution head 5 to press the distribution head 5 and the distribution disk onto the rotating disk.

The transmission gear 7 is located on the outside of the bearing seat 2, and the positioning ear plate of the distribution head 5 is positioned on the main shaft 1 outside the bearing seat 2 by the clamping spring 8.
[0048] In this embodiment, a dry oil pump 16 is provided at the end of the tank body 9. The dry oil pump 16 can inject oil into the bearing shell and also inject oil between the distribution plate and the rotating plate.

[0050] Specifically, the driving stirring mechanism below the feed port of the trough body 9 can cooperate with the rotating stirring mechanism to make the material more uniform when passing through the suction zone 18, and only a small amount of vacuum air volume is needed to adsorb the material on the surface of the filter cloth; such a setting can reduce the demand for vacuum air volume in the suction zone 18, and the excess vacuum air volume is used in the secondary pressurization zone 20 to improve the dehydration effect of the material.
[0051] In this embodiment, the outer end of the stirring shaft of the rotating stirring device is connected to a stirring driving mechanism 11, and the stirring driving mechanism 11 includes a stirring motor.
[0052] In this embodiment, the fan is a positive pressure fan that can provide positive pressure gas. The fan can be connected to the fourth pipeline, the pneumatic conveying pipe and the main air pipe 28 through branch pipelines. The positive pressure gas in the fourth pipeline is blown into the unloading area 21, so that a positive pressure environment is formed inside the filter cloth, so that the filter cake can fall off the filter cloth. The pneumatic conveying pipe is connected to a water supply component, and water is carried into the backwashing area 22 by pneumatic conveying, so as to realize backwashing of the filter cloth. The positive pressure gas in the main air pipe 28 enters the pneumatic stirring air pipe 29, and pneumatic stirring is performed between adjacent filter plates 6 to improve the uniformity of the material.
[0053] Optionally, a feeding box 13 is provided on one side of the tank body 9 close to its feed port, a plurality of feeding pipes are provided at the lower end of the feeding box 13 , and at least one feeding pipe is provided between adjacent filter plates 6 .
[0054] Specifically, a feed port is formed on one side of the trough body 9, and a discharge port is formed on the other side of the trough body 9. A feed box 13 is provided on the feed port. The material enters the trough body 9 through the feed box 13, and is evenly fed to the space between adjacent filter plates 6 through multiple feeding pipes at the lower end of the feed box 13, and is double stirred and mixed by a rotating stirring mechanism and a pneumatic stirring mechanism 30.
[0055] In this embodiment, overflow grooves 17 are provided on both sides of the feed box 13 .
[0056] Optionally, a discharge scraper 15 is provided on one side of the tank body 9 close to the discharge port thereof, and each filter plate 6 is arranged between two discharge scrapers 15 .
[0057] Specifically, the discharge scraper 15 can scrape the filter cake on the surface of the filter cloth on both sides of each filter plate 6, so that the dehydrated material falls off. An inclined guide plate can be set at the lower part of the discharge port of the trough body 9, and the scraped material falls onto the guide plate for guiding so as to be transported through the conveying mechanism.
[0058] Optionally, a plurality of scraper seats are provided on one side of the trough body 9 close to the discharge port, each discharge scraper 15 is connected to a scraper seat through an elastic component, and a limiting portion is provided between the discharge scraper 15 and the scraper seat, and the limiting portion is used to limit the position of the discharge scraper 15 so that the elastic component is in a pre-compression state.
[0059] Specifically, the edge side of the unloading scraper 15 is exposed from the side of each scraper seat close to the filter plate 6, the body side of the unloading plate is movably embedded in the scraper seat, and is connected to the scraper seat through an elastic component. The limiting part limits the unloading scraper 15 at a position close to its edge side, so that the elastic component is in a pre-compression state. In the non-unloading state, the distance between the unloading scraper 15 and the filter plate 6 is constant. In the unloading state, the edge side of the unloading scraper 15 contacts and scrapes the material cake. Since the intelligent multi-adsorption vacuum disc filter controls the thickness of the material cake, the thickness of the material cake will not be too thick. , and the thinner material cake is a challenge for the scraping of the discharge scraper 15, so an elastic component is provided, and the distance from the discharge scraper 15 to the filter plate 6 in the non-discharging state is made smaller than the distance between the traditional discharge scraper 15 and the material plate. When the discharge area 21 passes through the discharge scraper 15, due to the positive pressure gas provided by the fan, the filter cloth on the filter plate 6 moves outward, which can press the discharge scraper 15 and compress the elastic component. The use of the elastic component not only improves the scraping force of the discharge scraper 15 on the filter cloth, but also can control the scraping force not to be too large by setting the elastic coefficient, thereby protecting the filter cloth.
[0060] In this embodiment, the elastic component is a spring, and each unloading scraper 15 is connected to the scraper seat via at least a certain amount of springs.
[0061] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
