Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a filter plate moving system for a filter press. Background Art

[0002] Filter press is a solid-liquid separation equipment commonly used in chemical, pharmaceutical, food and other industries. In the chemical industry, filter press is often used in the solid-liquid separation process in the production process of petrochemical, fertilizer, dye, etc., which can effectively improve production efficiency, reduce waste treatment costs, and ensure product quality; in the pharmaceutical industry, filter press is widely used in the solid-liquid separation process in drug production. Its efficient filtering performance and reliable control system can ensure the purity and quality of the drug, meeting the strict requirements of drug production; in the food industry, filter press is often used in the solid-liquid separation process in the production process of fruit juice, wine, edible oil and other foods, which can achieve rapid filtration and separation of food raw materials, improve production efficiency, and ensure food hygiene and safety. In general, filter presses are widely used in chemical, pharmaceutical, food and other industries, providing reliable technical support for solid-liquid separation in the production process, and promoting the development and progress of the industry.

[0003] According to the machine form, filter presses are mainly divided into three types: vertical, side bar, and high beam. The filter plate of the high beam filter press is suspended on the beam of the frame, and does not contact the filtered and dehydrated products or sludge. It is suitable for clean environments, has a particularly stable structure, and a high degree of automation. Compared with other filtering equipment, the beam filter press dehydrator can maximize the dryness of the filter cake or product, with lower power consumption and lower maintenance work and costs.

[0004] In the existing high suspension beam filter press, the filter plate is connected to the suspension beam track through roller sliding, and the plate pulling mechanism drives the filter plate to move horizontally. For details, please refer to the Chinese patent "Filter Press Plate Pulling Mechanism and Working Method" with patent application number CN200610110545.3.

[0005] However, in the above scheme, when a large amount of filter dregs exists between the filter plates, the filter plates may tilt, and the rollers on the top of the filter plates will be lifted up and off the track, causing the filter plate moving system to unhook prematurely or jump when unloading the dregs. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a filter plate moving system for a filter press capable of realizing stable movement of the filter plate in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a filter press filter plate moving system, comprising a suspension beam and a plurality of filter plates suspended on the suspension beam in sequence along the left-right direction, characterized in that: the suspension beam is provided with at least two first guide rails and at least two limit strips corresponding to the first guide rails, each of the first guide rails and the limit strips extends along the left-right direction, the limit strips are located directly above the corresponding first guide rails, at least two first rollers corresponding to the first guide rails are installed on the top of the filter plate, the rotation axis of each of the first rollers extends along the front-back direction, the rotation axes of at least two of the first rollers do not overlap, and each of the first rollers can be slidably installed above the corresponding first guide rail and limited below the corresponding limit strip.

[0008] In order to facilitate processing, the first rollers are at the same height.

[0009] In order to ensure stability, the number of the first rollers is two, and they are arranged in a central symmetric manner relative to the central axis of the filter plate in the vertical direction.

[0010] In order to facilitate the installation of the first roller, a wheel rod corresponding to the first roller is provided on the top of the filter plate, and each of the first rollers is rotatably connected to the side of the top end of the corresponding wheel rod.

[0011] In order to limit the lifting height of the first roller and ensure smooth rolling of the first roller, a gap exists between the first roller and the corresponding limit strip in the absence of external force.

[0012] In order to facilitate installation and maintenance, the suspension beam has a beam body, and the first guide rail and the limit strip are both arranged on the outside of the beam body.

[0013] In order to facilitate the pre-positioning of the filter plate and improve the movement stability, the suspension beam is provided with at least two second guide rails extending in the left-right direction, and at least two second rollers corresponding to the second guide rails are installed on the top of the filter plate, and the rotation axis of each second roller extends in the front-to-back direction, and the rotation axes of at least two second rollers do not overlap, and each second roller can be slidably installed above the corresponding second guide rail.

[0014] In order to facilitate processing, the first roller and the second roller are at the same height.

[0015] In order to ensure stability, the number of the second rollers is two, and they are arranged in a central symmetric manner relative to the central axis of the filter plate in the vertical direction.

[0016] In order to facilitate the installation of the second roller, a wing plate is provided in the middle position of the top of the filter plate, and the two second rollers are rotatably connected to the side portions at the front and rear ends of the wing plate respectively.

[0017] Compared with the prior art, the utility model has the advantages that: due to the setting of the limit strip, the lifting height of the first roller can be limited, thereby limiting the inclination angle of the filter plate, so that the filter plate can still move stably under the filter trough, solving the problem of premature unhooking and hook jumping caused by the overall lifting of the filter plate.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0025] like Figures 1 to 5 The figure shows a preferred embodiment of the filter plate moving system of the filter press of the utility model, which comprises a suspension beam 1, a plurality of filter plates 2 sequentially suspended on the suspension beam 1 in the left-right direction, and a pull rod mechanism 3 for driving the filter plates 2 to move in the left-right direction.

[0026] The suspension beam 1 includes a beam body 10, a first guide rail 11, a limit bar 12 and a second guide rail 13. Specifically, there are two beam bodies 10, which are arranged at intervals in the front-to-back direction, and each beam body 10 has a bottom plate 101 at the bottom; there are two first guide rails 11, which are respectively installed on the bottom plates 101 of the two beam bodies 10 in the left-right direction, and are located on the outside of the corresponding beam body 10, and each first guide rail 11 is at the same height; there are two limit bars 12, which are respectively installed on the bottom plates 101 of the two beam bodies 10 in the left-right direction through a mounting seat, and are located on the outside of the two beam bodies 10, each limit bar 12 corresponds to the above-mentioned first guide rail 11 one by one, and is located directly above the corresponding first guide rail 11, and each limit bar 12 is at the same height; there are two second guide rails 13, which are respectively installed on the bottom plates 101 of the two beam bodies 10 in the left-right direction, and are located between the two beam bodies 10, and each second guide rail 13 is at the same height as the first guide rail 11.

[0027] A wheel rod 21 is provided at the front and rear parts of the top of each filter plate 2. The side part of the top of each wheel rod 21 is rotatably connected to a first roller 22 whose rotation axis extends along the front-to-back direction. In this embodiment, the upper part of the wheel rod 21 located in the front extends obliquely to the right, and the upper part of the wheel rod 21 located in the rear extends obliquely to the left. The two wheel rods 21 are centrally symmetrically arranged relative to the central axis of the filter plate 2 along the vertical direction. Therefore, the two first rollers 22 are centrally symmetrically arranged relative to the central axis of the filter plate 2 along the vertical direction, and the rotation axes of the two first rollers 22 do not overlap. Each first roller 22 corresponds to the above-mentioned first guide rail 11 one by one and is at the same height. Each first roller 22 can be slidably installed above the corresponding first guide rail 11 and is limited below the corresponding limit strip 12. In this embodiment, in the state without external force, there is a small gap between the first roller 22 and the corresponding limit strip 12, which limits the lifting height of the first roller 22 while ensuring the smooth rolling of the first roller 22.

[0028] A wing plate 23 is provided at the middle position of the top of the filter plate 2. The side parts of the front and rear ends of the wing plate 23 are rotatably connected to the second rollers 24 whose rotation axes extend in the front and rear directions. The two second rollers 24 are centrally symmetrically arranged relative to the central axis of the filter plate 2 in the vertical direction, and the rotation axes of the two second rollers 24 do not overlap. Each second roller 24 corresponds to the second guide rail 13 one by one and is at the same height. Each second roller 24 can be slidably installed above the corresponding second guide rail 13. A base 25 is installed at the top of the wing plate 23. A filter plate hook 26 is hinged on the base 25. The head and tail of the filter plate hook 26 have a hook part and a groove part respectively. The hook part of the filter plate hook 26 on the rear filter plate 2 can hook the base 25 on the front filter plate 2 to connect.

[0029] The pull rod mechanism 3 includes a pull plate chain 31 installed on the beam body 10 and a pull plate hook 32 installed on the pull plate chain 31. The hook portion of the pull plate hook 32 can be hooked into the groove portion of the filter plate hook 26 on the filter plate 2 for connection.

[0030] The working principle of this embodiment is as follows:

[0031] (1) Filter pressing: All filter plates 2 are pressed to one side by a hydraulic press to separate the solid and liquid of the mixture;

[0032] (2) Unloading: The plate pulling chain 31 rotates to drive the plate pulling hook 32 to move from left to right. When the plate pulling hook 32 reaches the top of the outermost filter plate 2 and contacts the filter plate hook 26, it will fall into the groove of the filter plate hook 26, lift the hook of the filter plate hook 26, and separate it from the base 25 of the previous filter plate 2, completing the unloading process after filtration. When the plate pulling hook 32 pulls the filter plate hook 26 to pull the filter plate 2 to the rightmost end, the plate pulling hook 32 is separated under the action of the next filter plate hook 26, and the next filter plate hook 26 hooks the base 25 on the previous filter plate 2. After all the filter plates 2 are unloaded from left to right, a new round of filtration can be carried out;

[0033] It is worth noting that, during the unloading process, when the plate-pulling hook 32 pulls the plate-pulling hook 26 of the outermost filter plate 2, the hook portion of the plate-pulling hook 26 is lifted up and separated from the previous filter plate 2, and the filter plate 2 is dragged to the other side by the plate-pulling hook 32. However, when a large amount of filter residue is stored between the filter plates 2, the filter plates 2 may be greatly tilted, and the first roller 22 and the plate-pulling hook 26 are lifted up, so that the plate-pulling hook 32 cannot smoothly complete the work of hooking the plate-pulling hook 26 and separating the filter plates 2.

[0034] In this application, if Figure 1 and Figure 2 As shown, due to the setting of the limit strip 12, the lifting height of the first roller 22 can be limited, thereby limiting the inclination angle of the filter plate 2, so that the filter plate 2 can be stably dragged away under the filter trough, solving the problem of premature unhooking and hook jumping caused by the overall lifting of the filter plate 1; at the same time, since these components are located outside the beam body 10, they are convenient for installation and maintenance.
