In addition, the terms "first", "second" and the like are only used to distinguish description, and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present application, it is also necessary to explain that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] The pull plate chain supporting assembly in the present application is mainly used on the suspension beam plate frame filter press, and necessary support, positioning and guiding structure are arranged on the transmission chain to ensure the linear reciprocating movement state of the transmission chain and the stable reliability of the pull plate mechanism.

[0034] Referring to Figures 1-3 , and combining Figure 4 , the pull plate chain supporting assembly in the present application comprises a guide rail 1 for guiding and a plurality of support wheel groups 2 for positioning and supporting the pull plate chain 3.

[0035] In order to effectively prevent the pull plate chain 3 from falling, the plurality of support wheel groups 2 are arranged at intervals in the length direction of the pull plate chain 3, and preferably, the plurality of support wheel groups 2 are arranged at intervals in the length direction of the pull plate chain 3 in the form of equal intervals, so as to enhance the uniform stability of the positioning and supporting of the pull plate chain 3.

[0036] From the specific structure of the positioning and supporting, each support wheel group 2 comprises a wheel group support, and the pull plate chain 3 is integrally connected between the plurality of wheel group supports in the form of multi-point connection, so that the pull plate chain 3 can be positioned and supported by the wheel group support at intervals in length.

[0037] In the running process, the pull plate chain 3 moves reciprocally under the action of the driving sprocket, and the support wheel group 2 mainly moves linearly along the guide rail 1 in a driven manner following the reciprocating movement of the pull plate chain 3, and positions and guides the movement direction of the pull plate chain 3.

[0038] The pull plate chain supporting assembly can effectively guide the movement of the pull plate chain 3, and specifically, the wheel group support is connected with a pair of follow-up rollers 4 arranged in pairs, the follow-up rollers 4 are installed in the guide grooves 11 located on both sides of the guide rail 1, and the wheel group support translates along the guide rail 1 as a whole through the limited rolling of the follow-up rollers 4 in the guide grooves 11.

[0039] Through the pull plate chain supporting assembly in the present application, several to ten supporting wheel groups 2 on the pull plate chain 3 can be formed, the follow-up rollers 4 of the supporting wheel groups 2 are installed in the guide groove 11 of the suspension beam inner guide rail 1, and the wheel group support is coupled with the multi-point supporting of the pull plate chain 3, so that the pull plate chain 3 can rely on the positioning and guiding of the supporting wheel groups 2 to realize stable and reliable reciprocating movement, thereby driving the pull plate manipulator to complete the pull plate task.

[0040] In one specific embodiment, the guide rail 1 is a full-length structure, which is installed in the suspension beam of the suspension beam plate frame filter press. Based on the linear structure of the suspension beam, the full-length structure of the guide rail 1 installed in the suspension beam can play a good linear guiding role.

[0041] Further, the guide rail 1 includes a groove-shaped rail for limiting the rolling of the follow-up roller 4, and the guide rail 1 extends according to the intended movement direction of the pull plate chain 3, so that the pull plate chain 3 can reciprocate along the intended regulation route.

[0042] The wheel group support in the present embodiment includes a fixed support 21 with a U-shaped cross section, which is installed with the opening downward, and two chain connecting pieces 22 are oppositely arranged on the top wall of the fixed support 21. By arranging two oppositely arranged chain connecting pieces 22, the pull plate chain 3 can be supported and connected between the two chain connecting pieces 22, and the positioning of the pull plate chain 3 is maintained.

[0043] From the perspective of multi-point supporting connection of the pull plate chain 3, a penetrating shaft 23 is arranged between the two chain connecting pieces 22 on each wheel group support, which penetrates through the two chain connecting pieces 22 and the pull plate chain 3 clamped between the two chain connecting pieces 22.

[0044] More specifically, the penetrating shaft 23 penetrates through one pair of chain plates on the pull plate chain 3 after penetrating through one of the single chain connecting pieces 22 on one side, and finally penetrates out of the other single chain connecting piece 22 on the other side, thereby completing the fixing of the pull plate chain 3 on the chain connecting piece 22. The penetrating shaft 23 between the chain connecting pieces 22 can be fixed by riveting, so that it can be fastened on the chain connecting piece 22 in the same connection form as between different chain plates.

[0045] For the multi-point positioning and supporting connection of the pull plate chain 3 on the multiple wheel group supports as described above, the chain connecting piece 22 is fixed and hoisted by a connecting fastener 24, and the connecting fastener 24 includes two pairs corresponding to the two chain connecting pieces 22. That is, each chain connecting piece 22 is fastened and connected on the wheel group support by a pair of connecting fasteners 24, thereby ensuring that the pull plate chain 3 is stably and reliably positioned and supported on the wheel group support through the chain connecting piece 22.

[0046] In another specific embodiment, based on the extension of the guide rail 1 along the intended moving direction of the pull plate chain 3, in order to ensure that the wheel set support can effectively and reliably move in the guide rail 1, it is necessary to ensure the freedom and flexibility of the rotation of the follow-up roller 4.

[0047] Specifically, the follow-up roller 4 is installed on the wheel set support through the roller shaft 5, the roller shaft 5 is a stainless steel roller shaft 5, and the roller shaft 5 penetrates through the side wall of the wheel set support and is in interference fit with the wheel set support. Through the interference fit between the roller shaft 5 and the wheel hole on the side wall of the wheel set support, the roller shaft 5 and the wheel set support can be connected as a whole structure.

[0048] Further, the follow-up roller 4 is a hollow nylon roller, which can be sleeved on the outside of the roller shaft 5. The hollow nylon roller includes an installation wheel cavity 41. By setting the installation wheel cavity 41 in a clearance fit relationship with the roller shaft 5, and further maintaining a gap of 0.1-0.15mm between the installation wheel cavity 41 and the roller shaft 5, the follow-up roller 4 can follow the overall structure of the roller shaft 5 and the wheel set support in the guide rail 1 in a freely rolling state.

[0049] The roller shaft 5 is fixedly installed on the two wing side walls of the fixed support 21 through the wheel shaft fastener 51. The wheel shaft fastener 51 is arranged on both sides of the inner side of the fixed support 21, and is respectively in screw joint fit with the connecting counterbore of the roller shaft 5.

[0050] Through this kind of setting mode, on the basis of the interference fit between the roller shaft 5 and the wheel set support, the fixed installation of the roller shaft 5 on the wheel set support is further ensured, which prevents the roller shaft 5 from being separated from the wheel set support during operation.

[0051] In order to ensure the stability of the rotation of the follow-up roller 4 and avoid its deflection, the follow-up roller 4 is arranged on the outer side of the two wings of the fixed support 21 and can be effectively accommodated in the guide groove 11 of the guide rail 1.

[0052] Preferably, the follow-up roller 4 includes a wheel body 43 with a tapered cross section, and the cross section of the guide groove 11 is also tapered, which can enable the follow-up roller 4 to be effectively and stably rolled in the guide groove 11.

[0053] Further preferably, the follow-up roller 4 further includes a limiting rim 42 arranged at the end of the follow-up roller 4 close to the side of the wheel set support and located between the fixed support 21 and the guide rail 1. In combination with the fixation of the guide rail 1 and the fixed connection of the roller shaft 5 and the fixed support 21, the follow-up roller 4 can be freely rotated under the limiting action of the limiting rim 42, avoiding the risk of deflection and derailment.

[0054] The material of the follow-up roller 4 includes nylon, the material of the wheel set support includes reinforced glass fiber nylon, and the material of the guide rail 1 includes stainless steel.

[0055] Specifically, the follow-up roller 4 is made of nylon 66, the wheel set support is casted by nylon 66+30% reinforced glass fiber, and the roller shaft 5 is made of stainless steel 2Cr13.

[0056] The guide rail 1 is made of stainless steel 304, thereby avoiding the corrosion risk caused by the fact that the plate-and-frame filter press often works in a corrosive environment.

[0057] Compared with the steel roller, the follow-up roller 4 made of nylon and the guide rail 1 made of stainless steel, and the follow-up roller 4 made of nylon and the roller shaft 5 made of stainless steel, do not need to consider the angle of mechanical lubrication, thereby reducing the risk that the lubricating oil and the corrosion and the metal scraps form a sludge to hinder the normal operation of the follow-up roller 4, and greatly reducing the wear and tear of the follow-up roller 4 and relieving the wear and tear of the guide rail 1.

[0058] Further, the operation problem caused by corrosion and sludge is eliminated, and the stability and service life of the plate pulling chain 3 are greatly improved.

[0059] In addition, the follow-up roller 4 made of nylon also reduces the noise generated in the rolling process of the steel structure, improves the production environment, and reduces the working noise to 20Hz, thereby promoting the reduction of manufacturing cost.

[0060] The utility model also provides a kind of suspension beam plate-and-frame filter press, including plate pulling chain 3 and the aforementioned plate pulling chain support assembly, plate pulling chain 3 is connected in plate pulling chain support assembly reciprocatingly, and it can be supported, positioned and guided under the action of plate pulling chain support assembly. It can guarantee the stability of plate pulling chain 3 to the greatest extent, and avoid the risk of breaking plate pulling chain 3.

[0061] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0062] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
