Description

Technical Field

[0001] The utility model relates to the field of filter presses, in particular to a vibration and unloading mechanism of a filter press. Background Art

[0002] Filter press is a device used for separation of solid and liquid, and is widely used in municipal environmental protection, food and beverage, chemical pharmaceutical, petrochemical, printing and dyeing, papermaking, and other related industrial industries. When the filter press is working, the material is squeezed and dehydrated to obtain sludge cake and liquid. The obtained sludge cake is easy to stick to the filter cloth and is difficult to separate. The traditional solution requires manual peeling or cake scraper unloading, which not only has low filtration efficiency and high labor intensity for workers, but also easily damages the filter cloth.

[0003] Patent CN212818343U discloses a continuous plate pulling and vibration unloading system for a filter press, which can continuously and stably complete the plate pulling and vibration actions by coordinating the vibration components, clamping components and limit components on the plate pulling trolley with the filter plates, thus achieving a high production efficiency. However, the following problems still exist in actual operation:

[0004] First, when the rapping assembly is set up, a connecting top pin is set between the top plate and the cylinder rod due to insufficient stroke of the rapping cylinder. The specific rapping process is as follows: the filter plate is first lifted by the rapping cylinder, and then the filter plate is suddenly retracted by the rapping cylinder to realize the rapping process. Long-term rapping will not only cause the connecting screws between the top pin and the top plate to loosen, but also the slender screw at the connection between the top pin and the cylinder rod will be easily broken due to the uncertain force direction.

[0005] Secondly, when the large square filter press is equipped with a vibrating unloading system, the length of the whole machine will increase significantly, and the running stroke of the drag chain will also increase accordingly. When the drag chain is pulled forward, excessive sagging and bending will occur, such as Figure 1 As shown, in this case, it is very easy to break when pushing back to reduce. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, the utility model provides a vibration unloading mechanism for a filter press, which effectively solves the problems in the prior art that a top pin is easily broken due to uncertain force direction and a drag chain is easily broken due to excessive sagging and bending, thereby greatly improving the reliability of the operation of the filter press.

[0009] The rapping seat includes a top plate, and two legs are integrally connected to the bottom of the top plate. The two legs are matched with two cylinder rods, and each leg is provided with a step hole that passes through the top plate. The rapping seat is fixed to the cylinder rod through the step hole by screws.

[0010] Preferably, the rapping seat adopts a π-type integrated seat.

[0013] Preferably, the drag chain box comprises a supporting bottom plate and an outer baffle plate, the height of the outer baffle plate is higher than the overall height of the drag chain, and the supporting wheel is mounted on the outer baffle plate.

[0014] Preferably, a mounting hole is provided on the outer baffle plate, and the supporting wheel comprises a fixed shaft and a roller rotatably arranged thereon, and the outer end of the fixed shaft passes through the mounting hole and is fixed to the outer baffle plate via a nut.

[0015] The utility model adopts the above technical solution, and has the advantages of:

[0016] 1. The vibration unloading mechanism of the filter press has a vibration seat which is constructed as an integrated structure by a top plate and two legs, and has a high structural strength; it is connected to the cylinder rod by screws penetrating the vibration seat, so as to facilitate the construction of a vibration assembly with high structural strength. Specifically, such a connection makes the bottom end face of the leg and the top of the cylinder rod directly contact, and the contact surface of the two is relatively large, so that the upper and lower forces and the horizontal forces are improved, which greatly improves the operational reliability of the vibration assembly and effectively solves the problem in the prior art that the top pin is easy to break due to the uncertain force direction. In addition, the vibration assembly uses fewer parts, is simple to assemble, and has improved reliability.

[0017] The rapping seat can specifically take the form of an n-type integrated seat or a π-type integrated seat, and the π-type integrated seat has relatively higher structural strength.

[0018] 2. The vibration unloading mechanism of the filter press can better support the drag chain during the forward pulling and backward pushing of the drag chain by supporting the supporting wheel, the drag chain box and the drag chain, effectively solving the problem of excessive sagging, bending and easy breakage of the drag chain when pulled forward, and greatly improving the reliability of the operation of the filter press.

It is characterized in that the vibration assembly 22 comprises two telescopic cylinders 221 arranged in parallel on the frame 21 along the direction of the guide rail 1, and the cylinder rods of the telescopic cylinders 221 extend upward, and a vibration seat 222 is connected to the ends of the two cylinder rods, and the vibration seat 222 comprises a top plate 2221, and two legs 2222 are integrally connected to the bottom of the top plate 2221. The two legs 2222 are arranged in cooperation with the two cylinder rods, and each leg is provided with a step hole 2223 arranged through the top plate 2221, and the vibration seat is fixed to the cylinder rod through the step hole by screws. In the above-mentioned rapping assembly, the rapping seat of the integrated structure not only has high structural strength, but is also connected to the cylinder rod by means of screws penetrating the rapping seat, so that the rapping assembly has high strength in use, thereby greatly improving the operational reliability of the rapping assembly.
