Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter technology, and in particular to a multi-roller vibrating press. Background Technology
[0002] A vacuum filter is a filtration device that uses vacuum suction as the filtration power. Its core principle is to create a vacuum environment on one side of the filter medium, so that the liquid to be filtered passes through the filter medium under the pressure difference between atmospheric pressure and the vacuum, while solid particles are trapped on the surface of the filter medium, thereby achieving solid-liquid separation.
[0003] Chinese patent CN201720511846.0 discloses a top-mounted vacuum filter. Multiple top mounts are arranged side-by-side along the conveying direction of the upper conveyor belt below the upper conveyor belt. A wear-resistant seat is fixed to the top of each top mount, and a belt-supporting groove extending along the conveying direction of the upper conveyor belt is formed on the top of the wear-resistant seat. An upper belt is placed in the belt-supporting groove. A roller is fixed below the upper conveyor belt on each top mount, and a lower belt is placed above the roller. The upper and lower belts form a ring-shaped belt support. This invention replaces the upper roller with a top mount, significantly reducing the number of parts and thus greatly reducing the probability of failure. The belt supports move along with the conveyor belt during operation, constantly lubricating and cooling it with water. This not only provides excellent conveying performance but also results in a low failure rate.
[0004] However, in actual production, as the filtration process proceeds, the liquid on the surface of the filter cake is quickly drawn away, while the internal liquid does not have time to diffuse evenly. This causes the surface of the filter cake to dry and shrink prematurely, making it unable to fully adhere to the surface of the conveyor belt to form a vacuum effect. This results in low efficiency of subsequent vacuum water suction and incomplete filtration. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-roller vibratory press. By setting a vibratory pressing mechanism on the filter, the vibratory pressing mechanism includes a frame, a vibrator, and pressing rollers. Filter cloths connected end to end are arranged around both. The pressing rollers continuously squeeze the filter cake to prevent it from cracking. At the same time, the vibrator continuously beats the filter cake, further preventing it from cracking and improving the filtration efficiency of water in the filter cake, thereby improving the filtration quality and completing solid-liquid separation.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-roller vibratory press, including a filter, wherein a vibratory pressing mechanism is provided on the filter, the vibratory pressing mechanism including a frame, a vibrator, a pressing roller and a filter cloth; the frame is installed above the filter, and the frame is provided with the vibrator and the pressing roller; the filter cloth is connected end to end and arranged around the vibrator and the pressing roller; the filter conveys and filters filter cake, the pressing roller continuously squeezes the filter cloth to cover the filter cake, and the vibrator beats the filter cake with high-frequency vibration to fully discharge the water in the filter cake.
[0007] As an improvement, the vibration pressing mechanism is located in the latter half of the filter production line.
[0008] As an improvement, each of the pressing rollers is provided with several sets; at least one set of the vibrators is located downstream of the pressing rollers.
[0009] As an improvement, the vibrating end of the vibrator and the press roller are in close contact with the filter cloth.
[0010] As an improvement, tension rollers are installed at both ends of the frame, and the tension rollers are surrounded by the filter cloth and located at both ends thereon.
[0011] As an improvement, one end of the tensioning roller is connected to a tensioning cylinder, and the tensioning roller is moved by the push rod of the tensioning cylinder.
[0012] As an improvement, a power element is provided on the other end of the tensioning roller, and the tensioning roller is driven by the power element.
[0013] As an improvement, the frame is provided with a correction mechanism, which is located at the top of the frame and surrounded by the filter cloth.
[0014] As an improvement, the frame is also provided with a scraper, which is located on the outside of the filter cloth and the blade is close to the filter cloth.
[0015] The beneficial effects of this utility model are as follows:
[0016] (1) This utility model uses a pressing roller to continuously squeeze the filter cloth to press the filter cake, and then uses a vibrator to vibrate at high frequency to keep the filter cake attached to the surface of the filter machine's track, thus ensuring the vacuum effect of the vacuum chamber and improving the vacuum filtration efficiency.
[0017] (2) By setting the vibrating end of the vibrator to be close to the filter cloth, the filter cake that is pressed by the filter cloth is more easily shaken off by vibration, reducing the time of subsequent manual cleaning. A scraper is set on the outside of the filter cloth to further improve the cleaning effect, save cleaning time, and improve the efficiency of filtration production.
[0018] (3) This utility model controls the tension of the filter cloth by setting a tension cylinder to adjust the tension roller, ensuring that the tension of the conveyor belt is in the best state, avoiding the conveyor belt being too loose or too tight, so that the filter cloth fits the filter cake, and improving the operating stability and reliability of the equipment.
[0019] In summary, this utility model has the advantages of high solid-liquid separation capability, strong dehydration capability, convenient cleaning, and stable operation. Attached Figure Description

[0029] Example 1
[0030] like Figures 1 to 5 As shown, this embodiment provides a multi-roller vibratory press, including a filter 1. The filter 1 is equipped with a vibratory pressing mechanism 2, which includes a frame 21, a vibrator 22, a pressing roller 23, and a filter cloth 24. The frame 21 is installed above the filter 1, and the frame 21 is equipped with the vibrator 22 and the pressing roller 23. The filter cloth 24 is connected end to end and surrounds the vibrator 22 and the pressing roller 23. The filter 1 conveys and filters the material to be filtered. The pressing roller 23 continuously squeezes the filter cloth 24 to press the filter cake formed after filtration. The vibrator 22 beats the filter cake by vibration, causing the cracked filter cake to reform into a complete filter cake and adhere to the surface of the conveyor belt, thereby improving the vacuum filtration quality.
[0031] Vibrator 22 is a high-frequency vibrator, which is existing technology and will not be described in detail here.
[0032] like Figure 1 As shown, the vibration pressing mechanism 2 is located in the latter half of the filter machine 1 production line.
[0033] It should be noted that after the vacuum suction at the front of the production line, the liquid on the surface of the filter cake is quickly removed, while the internal liquid does not have time to diffuse evenly. At this time, the vibrating pressing mechanism 2 in the second half of the production line can press the filter cake to allow the internal liquid to diffuse out and be suctioned.
[0034] like Figure 2 As shown, the press roller 23 and the vibrator 22 are provided in several groups; at least one group of the vibrator 22 is provided downstream of the press roller 23.
[0035] Specifically, the multiple sets of rolling rollers 23 can roll the filter cake multiple times, compacting it and making it less prone to breakage. At the same time, the rolling process promotes the faster discharge of liquid from the filter cake. This is because the rolling process increases the pressure difference of the liquid in the filter cake, making it easier for the liquid to pass through the filter medium under the action of vacuum suction, thus improving working efficiency.
[0036] In addition, the downstream vibrator 22 can further break down the cell walls of the biomass and release water after compaction, thus avoiding liquid residue.
[0037] like Figure 3 As shown, the vibrating end of the vibrator 22 and the press roller 23 are in close contact with the filter cloth 24.
[0038] It is worth mentioning that the close contact allows the two to better drive the filter cloth 24 to move, and the vibration makes it easier to shake off the filter cake that is pressed and stuck to the filter cloth, reducing the time for subsequent manual cleaning. The scraper set on the outside of the filter cloth further improves the cleaning effect, saves cleaning time, and improves the efficiency of filtration production.
[0039] like Figure 4 As shown, tension rollers 25 are installed at both ends of the frame 21, and the tension rollers 25 are surrounded by the filter cloth 24 and located at both ends thereon.
[0040] Maintaining proper tension in the filter cloth 24 is crucial for its normal operation. The tensioning roller 25 ensures that the filter cloth 24 can still operate stably during the pressing process. The filter cloth 24 operates passively, moving with the filter cake on the filter press 1. The tensioned filter cloth 24 will not slip due to insufficient tension.
[0041] like Figure 4 As shown, one end of the tensioning roller 25 is connected to a tensioning cylinder 26, and the tensioning roller 25 is moved by the push rod of the tensioning cylinder 26.
[0042] Understandably, the tension cylinder 26 allows the tension roller 25 to dynamically adjust the tension of the filter cloth 24, compensating for changes that occur during production. When the filter cloth 24 stretches, the tension roller 25 can tighten the filter cloth 24; when the filter cloth 24 contracts, the tension roller can loosen the tension on the filter cloth 24, ensuring that the filter cloth 24 always remains within a suitable tension range, enabling the equipment to adapt to various environmental and operating conditions.
[0043] like Figure 2 As shown, a correction mechanism 28 is provided on the frame 21. The correction mechanism 28 is located on the top of the frame 21 and is surrounded by the filter cloth 24.
[0044] The correction mechanism 28 is similar in structure to the correction device in Chinese Patent No. 202321824727.2, and adjusts the position of the filter cloth 24 so that the filter cloth 24 can completely cover the filter cake below during the production process.
[0045] like Figure 5As shown, a scraper 29 is also provided on the frame 21. The scraper 29 is located on the outside of the filter cloth 24, and the blade is close to the filter cloth 24.
[0046] It is worth mentioning that the scraper 29 can further physically scrape off the filter cloth 24 after it has been shaken and cleaned, thereby improving the cleaning effect, saving cleaning time, and increasing the efficiency of filtration production.
[0047] Example 2
[0048] like Figure 2 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to by the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that: a multi-roller vibratory press is provided with a power component 27 on the tension roller 25 at the other end, and the tension roller 25 is driven by the power component 27.
[0049] To further ensure that the filter cloth 2 does not slip, a power component 27 is provided to drive the tension roller 25 to rotate, thereby driving the filter cloth 24 to rotate; the rotation speed of the power component 27 corresponds to the transmission speed and transmission direction of the filter machine 1, ensuring that the filter cloth 24 and the filter cake operate synchronously.
[0050] Work steps
[0051] The filter cake is conveyed on the filter press 1. When it reaches the vibrating pressing mechanism 2 in the latter half of the conveyor, the filter cloth 24 is pressed and drained by the limiting pressure of the pressing roller 23. The pressed filter cake continues to be conveyed. When it reaches the vibrator 22, the cracked filter cake is beaten and reformed into a complete filter cake that adheres to the surface of the conveyor belt, improving the vacuum filtration quality of the conveyor belt. This process is repeated through several sets of pressing rollers 23 and vibrators 22. At the same time, the power unit 29 drives the filter cloth 24 to keep it running synchronously with the conveyor belt below via the tension roller 25.
[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
