Description

Technical Field

[0001] The utility model relates to the technical field of filter press cleaning, in particular to a filter press vibration device. Background Art

[0002] Filter press is a solid-liquid separation equipment, which is mainly used to separate the liquid part of a solid-liquid mixture by pressure, so as to obtain a relatively pure solid or liquid. It is widely used in many industries such as chemical, pharmaceutical, metallurgy, food, and environmental protection.

[0003] The working principle of the filter press is: first, the solid-liquid mixture to be separated is fed into the hopper of the filter press through the feed pipe. These mixtures may be suspensions, emulsions, or solutions containing solid particles. When the mixture enters the filter press, it flows through a series of filtration areas consisting of filter cloths or filter plates. These filter cloths or filter plates can prevent solid particles from passing through, while allowing liquid to partially pass through. As the filtration proceeds, the solid particles gradually form a layer of filter cake on the filter cloth or filter plate. In order to speed up the filtration process and improve the separation effect, the filter press usually applies pressure to the filter cake in some way (such as a hydraulic cylinder, pneumatic cylinder or mechanical device). This pressure forces more liquid to pass through the filter cloth or filter plate, thereby reducing the liquid content in the filter cake. The liquid that passes through the filter cloth (called filtrate) flows into a collection container for subsequent treatment or utilization. When the filter cake reaches a certain thickness or the filtration process is completed, it needs to be unloaded from the filter press.

[0004] In the prior art, the filter cake produced during the filter press process is generally vibrated on the filter plate to shake the filter cake off the filter plate by vibration. However, the general vibrating structure can only vibrate the filter plates one by one, and the vibration effect is good. When there are too many filter plates, vibrating them one by one will have too low work efficiency and take too long. Utility Model Content

[0005] The utility model aims to provide a filter press vibration device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A filter press vibration device comprises a frame; the frame comprises a fixed end, an extrusion end and a cross bar, one side of the extrusion end is fixedly connected to an extrusion cylinder, and the other end is slidably connected to a pressure plate, and the pressure plate is fixedly connected to the movable end of the extrusion cylinder; a plurality of filter plates are arranged on the side of the pressure plate close to the fixed end, and side ears are symmetrically fixedly connected to the side edges of the filter plates, the side ears are U-shaped, a first spring is fixedly connected to the groove of the side ears, and the bottom end of the side ears is slidably connected to the cross bar; a lifting assembly is fixedly connected to the cross bar, and the lifting assembly is used to lift the filter plates together and press and vibrate the filter plates up and down.

[0008] When the filter press is working, the extrusion cylinder is started, and the extrusion cylinder will drive the pressure plate to squeeze the filter plate, thereby improving the sewage separation effect of the filter plate and compressing the impurities into a cake shape. When the filtration is completed, the lifting component will drive the filter plate to a certain height through the lifting component to separate the side ears from the cross bar. Then the lifting component presses the filter plate up and down, and the filter plate vibrates up and down under the action of the first spring, thereby accelerating the separation of the filter cake on the filter plate and the filter plate.

[0009] The further improvement of the technical solution of the utility model is that: the lifting assembly includes four lifting legs and lifting rods arranged symmetrically, the lifting legs are provided with lifting slots, the lifting slots are open on the sides, and the lifting rods are slidably connected inside the lifting slots, the lifting rods are fixedly connected to each other, the top of the lifting rods is fixedly connected to a suspension beam, and the suspension beam and the lifting rods are fixedly connected; a pressing beam is fixedly connected between the two suspension beams, and a pressing assembly is provided on the pressing beam, and the pressing assembly is used to press the filter plate; a fixed rod is fixedly connected between the two lifting legs near the extrusion end, and a lifting cylinder is fixedly connected above the fixed rod and the fixed end, and the movable end of the lifting cylinder is fixedly connected to the suspension beam. The pressing assembly includes a pressing cylinder, and a plurality of extrusion rods are fixedly connected to the movable end of the pressing cylinder, and an extrusion block is fixedly connected to the lower end of a single extrusion rod.

[0010] The above technical solution is adopted. In this solution, when lifting, the lifting cylinder is started, the lifting cylinder drives the crossbeam to rise, the suspension beam rises and drives the lifting rod to rise, and the lifting rod is inserted into the groove of the U-shaped side ear on the side of the filter plate, thereby driving all the filter plates to rise together. After the filter plate rises, the pressing cylinder is started, and the pressing cylinder is extended and retracted several times to drive the extrusion block on the crossbeam to squeeze the upper end of the filter plate, so that the first spring is repeatedly compressed and rebounded, driving the filter plate to vibrate up and down, thereby accelerating the shedding of the filter cake. The width of the extrusion block is greater than the length of the gap between adjacent filter plates.

[0011] A further improvement of the technical solution of the utility model is that a scraper is fixedly provided at the lower end of the extrusion block.

[0012] The above technical solution is adopted. In this solution, a scraper is set. When the extrusion block moves up and down to extrude the filter plate, the scraper can help scrape the filter cake on the filter plate to prevent some filter cakes from being too sticky and unable to be completely removed by vibration alone.

[0013] A further improvement of the technical solution of the utility model is that two filter plates are arranged between the extrusion rods.

[0014] The above technical solution is adopted, in which the installation distance of the extrusion rod is set, that is, the installation distance of the extrusion block is set. The width of the extrusion block must be greater than the length of the gap between adjacent filter plates to extrude the filter plate. During extrusion, the extrusion block will extrude two filter plates at the same time. Therefore, the extrusion of the filter plates can also be achieved by setting the extrusion rods with two filter plates apart. Compared with the analysis that an extrusion block is set between each adjacent filter plate, the number of extrusion blocks installed can be reduced, thereby reducing losses.

[0015] A further improvement of the technical solution of the utility model is that: the upper end of the side ear is fixedly connected to a protrusion, the protrusion is fixedly connected to a second spring, and the second spring is fixedly connected to the protrusion on an adjacent side.

[0016] The above technical solution is adopted. In this solution, a second spring is set. When the filtration is completed, the rebound of the second spring will cause the pressure plates to shake back and forth, which will vibrate the filter cake in advance, and then the vibration of the first spring will make the filter cake easier to clean.

[0017] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0018] 1. The utility model provides a vibration device for a filter press. By arranging a lifting rod, a lifting rod and a first spring, the lifting rod is driven by the first cylinder, thereby driving the lifting rod and then driving all filter plates to rise together. The filter plates are pressed and vibrated together by the pressing cylinder, so that the vibration efficiency of the filter cake is improved.

[0019] 2. The utility model provides a vibration device for a filter press, wherein the installation distance of the extrusion rods is set, that is, the installation distance of the extrusion blocks is set. The width of the extrusion blocks must be greater than the length of the gaps between adjacent filter plates to extrude the filter plates. During extrusion, the extrusion blocks will extrude two filter plates at the same time. Therefore, by arranging the extrusion rods with two filter plates between them, the filter plates can also be extruded. Compared with arranging an extrusion block between each adjacent filter plate, the number of extrusion blocks installed can be reduced, thereby reducing losses.

[0020] 3. The utility model provides a vibrating device for a filter press. By setting a second spring, when the filtration is completed, the rebound of the second spring will cause the pressure plates to shake back and forth, and the filter cake is vibrated once in advance, and then the filter cake is easier to be cleaned up through the vibration of the first spring.

[0028] The present invention is further described in detail below in conjunction with the embodiments:

[0031] In this embodiment, when the filter press is working, the extrusion cylinder 5 is started, and the extrusion cylinder 5 will drive the pressure plate 6 to squeeze the filter plate 7, thereby improving the separation effect of the filter plate 7 for separating sewage and compressing the impurities into a cake shape. When the filtration is completed, the lifting component will drive the filter plate 7 to be lifted to a certain height through the lifting component, so that the side ears 8 are separated from the cross bar 4, and then the lifting component presses the filter plate 7 up and down, and under the action of the first spring 9, the filter plate 7 vibrates up and down, thereby accelerating the separation between the filter cake on the filter plate 7 and the filter plate 7.

[0032] like Figure 2As shown, in this embodiment, preferably, the lifting assembly includes four lifting legs 10 and a lifting rod 11 that are symmetrically arranged. The lifting legs 10 are provided with a lifting slot 12, which is open at the side. A lifting rod is slidably connected inside the lifting slot 12. The lifting rod 11 is fixedly connected to the lifting rod, and a suspension beam 13 is fixedly connected to the top of the lifting rod, and the suspension beam 13 is fixedly connected to the lifting rod; a pressing beam 14 is fixedly connected between the two suspension beams 13, and a pressing assembly is provided on the pressing beam 14, and the pressing assembly is used to press the filter plate 7; a fixed rod is fixedly connected between the two lifting legs 10 near the extrusion end 3, and a lifting cylinder 16 is fixedly connected above the fixed rod and the fixed end 2, and the movable end of the lifting cylinder 16 is fixedly connected to the suspension beam 13. The pressing assembly includes a pressing cylinder, and a plurality of extrusion rods 17 are fixedly connected to the movable end of the pressing cylinder, and an extrusion block 18 is fixedly connected to the lower end of a single extrusion rod 17.

After the filter plate 7 rises, the pressing cylinder is started, and the pressing cylinder is extended and retracted several times to drive the extrusion block 18 on the cross beam 14 to squeeze the upper end of the filter plate 7, so that the first spring 9 is repeatedly compressed and rebounded, driving the filter plate 7 to vibrate up and down, thereby accelerating the shedding of the filter cake. The width of the extrusion block 18 is greater than the length of the gap between adjacent filter plates 7.

[0034] A scraper 19 is fixedly provided at the lower end of the extrusion block 18 .

During extrusion, the extrusion block 18 will extrude two filter plates 7 at the same time. Therefore, the extrusion of the filter plates 7 can also be achieved by setting the extrusion rod 17 with two filter plates 7 between them. Compared with the analysis that an extrusion block 18 is set between each adjacent filter plate 7, the number of extrusion blocks 18 installed can be reduced, thereby reducing losses.

[0041] In this embodiment, by providing the second spring 21, when the filtration is completed, the rebound of the second spring 21 will cause the pressure plates to shake back and forth, thereby pre-vibrating the filter cake, and then the vibration of the first spring 9 makes it easier to clean the filter cake.

[0042] The following is a detailed description of the working principle of the filter press vibration device.

[0043] like Figure 1-5 As shown, when the filter press is working, the extrusion cylinder 5 is started, and the extrusion cylinder 5 will drive the pressure plate 6 to squeeze the filter plate 7, thereby improving the separation effect of the filter plate 7 for separating sewage and compressing the impurities into a cake shape. When the filtration is completed, the lifting cylinder 16 is started, and the lifting cylinder 16 drives the crossbeam 14 to rise, and the rise of the suspension beam 13 drives the lifting rod to rise and drives the lifting rod 11 to rise. The lifting rod 11 is inserted into the groove of the U-shaped side ear 8 on the side of the filter plate 7, thereby driving all the filter plates 7 to rise together. After the filter plate 7 rises, the pressing cylinder is started, and the pressing cylinder is extended and retracted for many times to drive the extrusion block 18 on the crossbeam 14 to squeeze the upper end of the filter plate 7, so that the first spring 9 is repeatedly compressed and rebounded, driving the filter plate 7 to vibrate up and down, thereby accelerating the shedding of the filter cake. The width of the extrusion block 18 is greater than the length of the gap between adjacent filter plates 7; by setting the scraper 19, when the extrusion block 18 moves up and down to extrude the filter plate 7, by setting the scraper 19, the scraper 19 can help scrape the filter cake on the filter plate 7; by setting the second spring 21, when the filtration is completed, the rebound of the second spring 21 will cause the pressure plates to shake back and forth, and the filter cake is vibrated in advance, and then the filter cake is easier to be cleaned up through the vibration of the first spring 9.
