Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a rubber belt filter and a roller chain belt support. Background Art

[0002] The rubber belt vacuum filter is a highly efficient solid-liquid separation device. It utilizes a fixed vacuum box over which an adhesive belt slides, creating a dynamic seal between the box and the belt. This device uses negative vacuum pressure as the driving force for solid-liquid separation. Structurally, the filtering sections are arranged horizontally along the length of the filter, enabling continuous and automatic filtration, cake washing, slag unloading, and filter cloth regeneration. The mother liquor and cake washing liquid can also be collected in sections. It offers advantages such as high filtration efficiency, high throughput, excellent washing efficiency, low cake moisture content, flexible operation, and simple maintenance. After years of refinement and improvement, the rubber belt filter has been widely used for solid-liquid separation in metallurgy, mining, chemical industry, papermaking, food, pharmaceuticals, coal washing, and environmental protection. It has found particular success in gypsum dehydration in flue gas desulfurization (FGD).

[0003] The rubber filter belt, also known as the rubber belt, is the core component of the rubber belt vacuum filter. The belt is annular, with its two ends respectively wrapped around the active roller and the driven roller. It is supported and tensioned by the active and driven rollers. The active roller rotates and drives the belt through friction. The middle part of the belt is supported by the upper and lower rollers. Since the upper middle part of the belt plays the role of carrying and filtering materials, the installation of this part of the belt requires it to be flat and straight, which results in a large number of upper rollers. The upper roller is a non-standard part, consisting of a roller, bearings, shaft, seals, and fixings. It has a certain processing and manufacturing cycle. In addition, due to processing errors and installation errors, the upper roller can easily rotate inflexibly, with a certain friction resistance, which increases the operating power consumption of the equipment.

[0027] This embodiment discloses a roller chain belt support for supporting a rubber filter belt 2 (referred to as the belt for short) of a rubber belt filter and the material thereon.

[0028] like Figure 1 As shown, the rubber belt filter primarily consists of a frame 1, a rubber filter belt 2, a driven roller 3, a feeding hopper 4, a belt support 5, an isolator 6, a vacuum box 7, a liquid collecting manifold 8, a drive reducer 9, a driving roller 10, a filter cloth 11, several redirecting rollers 12, a discharge scraper 13, a cleaning device 14, a correction device 15, and a tensioning device 16. The driven roller 3 is located at the head of the frame 1, and the driving roller 10 is located at the tail of the frame 1. They are driven by the reducer 9 to rotate. The vacuum box 7 is located in the upper center of the frame 1, extending along its length. The roller chain belt support 5 is located in the center of the frame 1 and is typically arranged in two groups to avoid the vacuum box 7. The roller chain belt support 5 runs parallel to the vacuum box 7 along the length of the frame 1. The rubber filter belt 2 is wound around a driving roller 10 and a driven roller 3 at each end. Its upper center portion is mounted on a vacuum box 7 and a roller chain belt support 5, sliding over these two supports. Its lower center portion is supported by lower rollers. The structure of a rubber belt filter is conventional and will not be described in detail here.

[0029] The present invention is described in detail below with reference to the embodiments.

[0030] Example 1

[0031] See also Figure 2In this embodiment, the roller chain belt support is connected to the frame 1 of the rubber belt filter, including two tensioning wheels 51 distributed near both sides of the frame, a support roller chain 52 arranged around the two tensioning wheels 51, and a support frame 53 for carrying the support roller chain 52.

[0032] Specifically, the support frame 53 is arranged along the length direction of the frame and is fixedly connected to the frame by fasteners. The fasteners can adopt a detachable connection structure such as bolts to facilitate the disassembly and assembly of the support frame 53. The two tensioning wheels 51 are rotatably connected to the two ends of the support frame 53 through the wheel support seat 54.

[0033] like Figure 2 As shown, the wheel support seat 54 includes a mounting side plate 541 fixedly connected to the end of the support frame 53 and an L-shaped support plate 542 fixedly connected to the mounting side plate 541. The tensioning wheel 51 is rotatably connected between the mounting side plate 541 and the L-shaped support plate 542 through a rotating shaft. After the support roller chain 52 is installed on the tensioning wheel 51, the other side of the L-shaped support plate 542 is fastened to the mounting side plate 541 with bolts to ensure the stable setting of the tensioning wheel 51.

[0034] The support roller chain 52 includes a roller chain belt 524 arranged in an annular shape and a plurality of rollers 522 rotatably arranged in the roller chain belt 524. In this embodiment, the roller chain belt 524 is made of a flexible plastic material with good acid, alkali and corrosion resistance. Specifically, the roller chain belt 524 is provided with a plurality of spaced connection holes along the length direction, each connection hole is arranged along the width direction of the roller chain belt 524, and the roller 522 is rotatably connected to the connection hole via a rotating shaft. Furthermore, the top of the roller 522 should be higher than the upper surface of the roller chain belt 524. When the support roller chain 52 carries the adhesive tape, the roller 522 is in direct contact with the adhesive tape, thereby forming a rolling friction fit between the adhesive tape and the support roller chain 52. This structure can reduce the running resistance of the adhesive tape, thereby achieving the purpose of energy saving and consumption reduction.

[0035] Combine Figure 5 and Figure 6 In order to match the annular structure of the support roller chain 52 and facilitate the support of the upper and lower parts of the support roller chain 52, in this embodiment, the support frame 53 is constructed as a C-shaped structure having an upper support surface 531 and a lower support surface 532. The upper support surface 531 is used to support the upper support roller chain 52, and the lower support surface 532 is used to support the lower support roller chain 52.

[0036] In order to reduce the wear of the support frame 53 caused by the movement of the roller 522 of the support roller chain 52, in this embodiment, a support slide 55 is further connected between the upper support surface 531 of the support frame 53 and the support roller chain 52, and the support roller chain 52 abuts against the support slide 55. In order to ensure the flatness of the upper end surface of the support slide 55 and prevent obstruction to the rolling of the roller 522, in this embodiment, the lower end surface of the support slide 55 is connected to the support frame 53. The specific structure is as follows: a T-shaped groove 551 is provided along the length direction on the lower end surface of the support slide 55, and a T-shaped connector 552 for connecting to the support frame 53 is inserted into the T-shaped groove 551. The vertical end of the T-shaped connector 552 is constructed as a plurality of connecting columns. Correspondingly, the upper support surface 531 of the support frame 53 is provided with a plurality of connecting holes that are compatible with the connecting columns. During assembly, the connecting columns of the T-shaped connector 552 are inserted into the connecting holes to fix the relative positions of the support slide 55 and the support frame 53. At the same time, the connection structure is also convenient for disassembly and assembly, making it easy to replace the support slide 55.

[0037] In this embodiment, the support slide 55 is preferably made of ultra-high molecular weight polyethylene, which is wear-resistant and corrosion-resistant and can extend the service life of the entire device.

[0038] Because the lower part of the support roller chain 52 does not support the tape, in order to reduce costs, there is no need to connect the support slide 55 between the lower support surface 532 of the support frame 53 and the support roller chain 52. In this embodiment, multiple groups of support platforms 56 are connected between the lower support surface 532 of the support frame 53 and the support roller chain 52. The support platforms 56 are fixedly connected to the side end or the lower support surface 532 of the support frame 53, and the number is set to 3-4 groups. This structure can reduce the contact area between the support roller chain 52 and the lower support surface 532.

[0039] In order to prevent the support roller chain 52 and its roller 522 from running off course, it is preferred that a limiting groove 553 is also provided at the top of the support slide 55. The limiting groove 553 is arranged along the length direction of the support slide 55, and the width of the limiting groove 553 roughly matches the length of the roller 522, which can limit the roller 522.

[0040] Example 2

[0041] The roller chain belt support provided in this embodiment has substantially the same structure as the roller chain belt support provided in Example 1. For the sake of brevity, only the differences are described in detail here.

[0042] See also Figure 3 、 Figure 4 as well as Figure 7In this embodiment, the roller chain belt 524 is arranged in sections. Specifically, the roller chain belt 524 includes several groups of connecting plates 521 connected end to end, and the rollers 522 are rotatably arranged in the connecting plates 521. The connecting plates 521 are provided with connecting holes along the width direction of the supporting roller chain 52, and the rollers 522 are rotatably connected in the connecting holes via a rotating shaft. The connecting plates 521 are respectively provided with connecting parts 523 at both ends. In this embodiment, the connecting parts 523 are constructed as a plurality of protrusions extending from the side edges of the connecting plates 521 to the distal end. The protrusions are spaced apart, and the protrusions at the both ends of the connecting plates 521 are staggered. The protrusions are provided with mounting holes. During installation, the protrusions of the connecting plates 521 are cross-connected, and the connecting shafts are installed in the mounting holes. The adjacent connecting plates 521 can be hinged, thereby forming a flexible roller chain structure.

[0043] Similarly, in this embodiment, the top of the roller 522 should be higher than the upper surface of the connecting plate 521. When the support roller chain 52 carries the tape, the roller 522 that rotates with the connecting plate 521 is in direct contact with the tape, thereby creating a rolling friction fit between the tape and the support roller chain 52.

[0044] The roller chain tape support provided in this embodiment has a simple structure and is easy to maintain. The roller chain can be modularly combined, with a short processing and manufacturing cycle. Installation, maintenance and replacement are very convenient. It can avoid the problems of inflexible rotation of the roller and friction resistance caused by processing errors or installation errors in the prior art. In addition, the roller 522 in this embodiment is made of self-lubricating material, which can achieve zero maintenance.

[0045] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
