[0002] The filter cloth of the filter press is a key component in the filter press, which is used to filter solid particles and separate liquids. The selection and use of the filter cloth directly affects the filtration efficiency and effect of the filter press. The material of the filter cloth: Polyester: wear-resistant and corrosion-resistant, suitable for most industrial applications. Polypropylene (Polypropy l ene): acid and alkali resistant, suitable for the chemical industry. Nylon (Nylon): high strength, suitable for high pressure and high temperature environments. Polytetrafluoroethylene (PTFE): high temperature and corrosion resistant, suitable for extreme environments. Cotton cloth: suitable for low pressure, low temperature and low corrosive environment. During the use of the filter cloth, the following matters need to be paid attention to for its installation and maintenance: Installation: Make sure the filter cloth is flat, wrinkle-free, and firmly installed. Cleaning: Clean the filter cloth regularly to remove blockages and restore filtration efficiency. Replacement: Replace the filter cloth in time according to the usage and the degree of wear of the filter cloth. Inspection: Check the wear and damage of the filter cloth regularly and repair or replace it in time.

[0003] The existing patent authorization number is: CN217526496U, which discloses a filter cloth suspension device for a fully automatic chamber filter press, which is arranged on the chamber plate of the fully automatic chamber filter press, and includes: a suspension frame, a filter cloth, an adjustment component, and a hanging rod; the suspension frames are rotatably mounted between adjacent chamber plates in pairs, and a hanging rod is hung between each pair of suspension frames, and the rod body of the hanging rod is detachably connected to one side of the filter cloth; a pair of filter cloths are sandwiched between two adjacent chamber plates, and a connecting hole with an elastic member is provided in the center of the filter cloth, which is used to be sleeved with the water inlet in the center of the chamber plate when the two adjacent chamber plates are fitted; the adjustment components are arranged in pairs between each pair of suspension frames, and each adjustment component is coupled to the surface of a filter cloth, which is used to flatten and separate the two filter cloths when the two adjacent chamber plates are separated. The device is detachably connected to a pair of hanging rods hung in the suspended frames through one side of the filter cloth. When replacing the filter cloth, it is only necessary to remove the hanging rod from the suspended frame, and then separate the filter cloth from the hanging rod to quickly replace the new filter cloth. After analyzing the above device, it can be found that its main function is to improve the ability to disassemble and replace the filter cloth by connecting each structure in a detachable installation manner. However, in actual use, firstly, the filter cloth installed in the device has a certain size. Each time the filter cloth is replaced and repaired, it can only be disassembled and replaced with a new one. It cannot be adjusted accordingly according to the filtering area requirements, that is, the use time of each filter cloth is short; secondly, during use, it is impossible to automatically clean the impurities on the filter cloth, and it is often necessary to use external tools or manual processing, which seriously affects the normal operation of the filter press; finally, when installing and disassembling the filter cloth, the above structure is relatively complicated, which is inconvenient to quickly fix and separate the filter cloth, and the operation is difficult;

[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a filter cloth rotating suspension device. Summary of the invention

[0005] The object of the present invention is to provide a filter cloth rotary suspension device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a filter cloth rotating suspension device, comprising a filter cloth, a suspension frame I, and a suspension frame II; the filter cloth is suspended on the outside of a filter plate by an external auxiliary part, the external auxiliary part controls the filter cloth to detach from the filter plate and controls the filter cloth to rotate up and down, the external auxiliary part comprises an suspension frame I and a suspension frame II with adjustable angles, the filter cloth is arranged in a rolling series between the outsides of the suspension frame I and the suspension frame II, the tops of the suspension frames I and II are rotatably connected with a top swinging part installed on the filter press plate, the bottom of the suspension frame I and the bottom of the suspension frame II are rotatably connected with a bottom adjusting part, the bottom adjusting part is horizontally telescopically matched with the top swinging part, so as to adjust the angle between the suspension frame I and the suspension frame II, and then adjust the inclined filtering angle of the filter cloth suspended and installed on the suspension frame I or the suspension frame II, the head and tail ends of the filter cloth are detachably connected with upper connecting rods through filter cloth fasteners, and are located between the suspension frames I and II. The filter cloth at the lower part is wound and passed through the lower connecting rod, pivot I, pivot II, which are rotatably arranged at the lower side of the suspension frame I and the suspension frame II. A transmission chain top swinging piece is connected between the upper connecting rod and the lower connecting rod at the inner side of the suspension frame I and the suspension frame II, and a rotating power piece is connected to the top of the transmission chain top swinging piece located on the suspension frame I. The rotating power piece drives the transmission chain top swinging piece at the lower side to rotate, and then the rotation of the filter cloth, the upper connecting rod, the lower connecting rod, the pivot I, and the pivot II realizes the rotational position adjustment of the filter cloth. When filtering different amounts of filtered objects, a filter of a suitable size is selected to be arranged on the outer side of the filter plate at the suspension frame II. At the same time, according to the use and loss of the filter cloth, the filter position is continuously changed by rotating the filter cloth, so as to increase the service life of each filter cloth, and by adjusting the angle between the suspension frame I and the suspension frame II, the filter cloth with a suitable inclination angle is controlled to filter, so as to increase the filtering accuracy and application range;

[0007] The vibration cleaning mechanism is arranged on the inner side of the filter cloth, and the inner end of the vibration cleaning mechanism is rotatably connected to the rotating shaft at the adjacent position. The rotating shaft includes a pivot I, a pivot II and chain teeth connected to the top of the suspension frame II and rotatably connected to the top swinging member of the transmission chain. When the rotating power member controls the filter to rotate and move the control rotating shaft, the vibration cleaning mechanism is synchronously driven to operate, and the moving filter cloth is laterally vibrated and rolled for cleaning, so that each time the position of the filter cloth is adjusted, the impurities adhered to the filter cloth during filtering are vibrated to a certain extent for cleaning, thereby improving the efficiency of subsequent filtration, thereby realizing the function of the device to synchronously vibrate and clean the filter cloth when the filter cloth is rotationally adjusted, thereby further improving the service life of the filter cloth.

[0008] Compared with the prior art, the invention has the following beneficial effects: by setting the bottom adjustment member, the angle of the suspension frame I and the suspension frame II can be adjusted to adjust the filtering angle of the filter cloth; at the same time, the filter cloth fastener is used to wind and suspend a single filter cloth between the suspension frame I and the suspension frame II, so that the filtering position of the filter cloth can be adjusted as needed without affecting its normal filtering use, so as to increase the use time of a single filter cloth and reduce the use cost; at the same time, the automatic rotation adjustment is simple to operate and has strong practicality;

[0009] By controlling the rotation and movement of the filter cloth and utilizing the transmission effect of the transmission belt to control the operation of the vibration plate and the cleaning roller brush in contact with the filter cloth, the filter cloth is subjected to cyclic vibration and rolling cleaning, thereby achieving automatic cleaning of the filter cloth during its operation, reducing its loss, increasing its service life, and further reducing the cost of filtration.

[0010] By adopting a single filter cloth for winding suspension and fixing it with filter cloth fasteners, the function of easy installation, replacement and flexibility of use is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, two sets of side springs 33 are symmetrically elastically connected between the positioning blocks 25 on both sides and the vibration plate 34. When the middle shaft 26 rotates and drives the swing plate frame 27 to rotate, a swing amplitude is generated. Then, under the connection of the telescopic member, the buffer rod 30 drives the middle spring 32 inside the sleeve 31 to produce a reciprocating swing within a certain stroke, thereby controlling the vibration plate 34 to continuously vibrate. At this time, the outer side of the vibration plate 34 is in contact with the filter cloth 2, so that the filter cloth 2 is vibrated during the rotation and movement, so as to shake and remove the impurities filtered and adhered on its surface;

[0036] The vibration plate 34 is evenly provided with perforated plates 56, which are used to ensure that the vibration plate 34 does not affect the normal filtration of the filter cloth 2 when it is in contact with the filter cloth 2 and vibrates;

[0037] It should be noted that the contact amplitude between the cleaning roller brush 39 and the filter cloth 2 is greater than the vibration amplitude of the filter cloth 2 controlled by the vibration plate 34, ensuring that the cleaning roller brush 39 can perform real-time contact cleaning on the filter cloth 2.

According to the filtering angle requirement, the piston rod at its end can be extended and retracted by starting the cylinder 20, and then the placement angle of the filter cloth 2 can be adjusted under the rotation connection between the swing shaft 21 and the connecting column 18, so that the filter cloth 2 can fully filter the filter material. At the same time, when the filter cloth 2 rotates and moves, the size of the direct filtering can be adjusted according to the use and consumption of the filter cloth 2 and the area required for filtering. When rotating and moving, the drive shaft 24 is driven to rotate by the transmission connection of the transmission belt 22, and then the vibration plate 34 is driven to cyclically vibrate the filter cloth 2 under the swinging operation of the structure such as the middle shaft 26, the buffer rod 30, the middle spring 32, and the side spring 33, and the plurality of cleaning roller brushes 39 are driven to roll and clean the inner side of the filter cloth 2 under the connection with the rotating sleeve 36, so that the filter cloth 2 can be cleaned quickly and conveniently, thereby prolonging its service life.
