Description

Technical Field

[0001] The present application relates to the technical field of vertical disc filtering equipment, and in particular to a spring compression device for a vertical disc distribution head. Background Art

[0002] Vertical distribution heads are usually installed on vertical filters to achieve the three stages of the filter, namely suction, drying and blowing off. The central axis of the vertical filter completes a filtration task every time it rotates one circle.

[0003] At present, the relevant vertical distribution head is installed on the filter body to maintain a sealed environment for the filtration space inside the filter body. The existing installation method is to fix the center of the distribution head with the central axis of the filter body. The distribution head includes a dynamic friction disk and a static friction disk. The dynamic friction disk is coaxially fixed with the central axis. The dynamic friction disk is rotatably installed at the center of the static friction disk. The static friction disk is fixed to the filter body by bolts, so that during the operation of the filter body, the distribution head and the central axis remain relatively stationary.

[0004] The above-mentioned related technologies have the following shortcomings: since a gap needs to be maintained between the distribution head and the filter body, and with the vibration and friction generated during the long-term operation of the equipment, the static wear-resistant disc is prone to produce an uneven contact surface, resulting in leakage at the vertical disc distribution head. Utility Model Content

[0005] In order to reduce material leakage from the vertical disk distribution head and improve operating efficiency, the present application provides a spring compression device for the vertical disk distribution head.

[0006] The present application provides a spring compression device for a vertical plate dispensing head, which adopts the following technical solution:

[0007] A spring compression device for a vertical disc distribution head comprises a distribution head mounted on a filter housing, the filter housing being equipped with a rotatable central axis, the distribution head comprising a dynamic friction disc and a static friction disc, the static friction disc being rotatably connected to the center of the dynamic friction disc, the static friction disc being coaxially fixedly connected to the central axis, the static friction disc being fixedly mounted on the filter housing, a compression mechanism being provided on the side of the static friction disc away from the central axis, the compression mechanism comprising a screw fixed on the filter housing, the axis of the screw being parallel to the central axis, a mounting block being fixed on the side of the static friction disc away from the central axis, the screw passing through the mounting block, a spring being abutted on the side of the screw away from the filter housing, a gasket being sleeved on the side of the spring away from the mounting block, a nut being threadedly connected to the screw, the nut being pressed against the side of the gasket away from the spring.

[0008] By adopting the above technical solution, a clamping mechanism is provided to adjust the gap and tighten the peripheral side of the distribution head. Under the joint action of the nut and the spring, the gap of the vertical disk distribution head can be effectively adjusted and maintained, and the spring can also provide a certain buffer, reducing the operating wear of the static friction disk, improving the stability of the equipment operation, and less prone to leakage.

[0009] Optionally, the pressing mechanism further includes a fixing block fixed on the filter housing, and the screw is fixed on the fixing block.

[0010] By adopting the above technical solution, the provision of the fixing block further increases the contact area between the screw and the filter housing, thereby enhancing the installation stability.

[0011] Optionally, there are multiple pressing mechanisms, and the multiple pressing mechanisms are all located on the circumference of the distribution head and symmetrically distributed about the center of the distribution head.

[0012] By adopting the above technical solution, multiple pressing mechanisms further enhance the fastening effect of the distribution head and reduce the occurrence of material leakage.

[0013] Optionally, an observation ruler is fixed on the filter housing for convenient observation of the gap between the distribution head and the filter housing, and the observation ruler is parallel to the axis of the central axis.

[0014] By adopting the above technical solution, the gap adjustment status can be directly observed through the observation ruler, thereby improving the installation efficiency.

[0015] Optionally, there are multiple observation rulers, and the multiple observation rulers are distributed at intervals around the dispensing head.

[0016] By adopting the above technical solution, multiple observation rulers facilitate observation of the gap distance around the distribution head, which facilitates quick installation.

[0017] Optionally, the position of the fixing block on the filter housing is adjustable.

[0018] By adopting the above technical solution, when it is necessary to install distribution heads of different diameters, the position of the screw can be easily changed by adjusting the fixed position of the fixing block on the filter housing, so that the screw can pass through the installation block, which is convenient for subsequent tightening and fixing.

[0019] Optionally, a trough body is fixed on the filter housing, the length direction of the trough body is perpendicular to the axis of the central axis, the fixed block is slidably installed in the trough body, and a plurality of threaded holes are opened through the side wall of the trough body. The plurality of threaded holes are opened at intervals along the length direction of the trough body, and the threaded inner holes of the threaded holes are connected with bolts, which pass through the threaded holes and are locked with the fixed block.

[0020] By adopting the above technical solution, when it is necessary to install distribution heads of different diameters, the position of the fixing block in the slide groove is adjusted and then fixed with bolts, so that the position of the screw can be changed accordingly, thereby meeting the requirements of tightening distribution heads of different diameters.

[0021] Optionally, an oil filling hole is provided on a side of the static friction disk close to the filter housing.

[0022] By adopting the above technical solution, oil is injected through the oil injection hole, which further ensures that the static friction disk and the filter housing can be lubricated by grease and maintain a seal.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. By setting a clamping mechanism, the clearance of the peripheral side of the distribution head is adjusted and tightened. Under the joint action of the nut and the spring, the clearance of the vertical disk distribution head can be effectively adjusted and maintained. The spring can also provide a certain buffer, reducing the operation wear of the static friction disk, improving the stability of the equipment operation, and less prone to leakage.

[0025] 2. Multiple clamping mechanisms further enhance the fastening effect of the distribution head and reduce material leakage.

[0026] 3. The gap adjustment status can be directly observed through the observation ruler, thereby improving installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0031] The embodiment of the present application discloses a spring compression device for a vertical tray dispensing head.

[0032] Reference Figure 1A spring compression device for a vertical disc distribution head includes a distribution head 2 vertically mounted on a filter housing 1. A horizontally arranged central shaft 11 is installed in the filter housing 1. During the filtration process, the end of the central shaft 11 away from the distribution head 2 rotates under the drive of a driving source. The distribution head 2 includes a dynamic friction disc 21 and a static friction disc 22. The dynamic friction disc 21 is coaxially and rotatably mounted at the center of the static friction disc 22. The dynamic friction disc 21 is fixedly connected to one end of the central shaft 11. A clamping mechanism 3 is provided around the static friction disc 22, which confines the static friction disc 22 to the filter housing 1, ensuring that leakage is unlikely to occur during its operation and improving the stability of the equipment operation.

[0033] The number of the clamping mechanisms 3 is multiple, and in this embodiment there are four. The four clamping mechanisms 3 are distributed around the static friction disc 22 and are symmetrically arranged about the center of the static friction disc 22. Each clamping mechanism 3 includes a fixed block 31 fixed on the filter housing 1, and a screw 32 is vertically fixed on the fixed block 31 so that the screw 32 is parallel to the axis of the central axis 11. A mounting block 33 is also fixed to the peripheral side wall of the static friction disc 22. The number of mounting blocks 33 is the same as the number of screws 32 and they are one-to-one opposite. The screws 32 pass through the mounting blocks 33 and are slidably connected to the mounting blocks 33. Each screw 32 is sleeved with two annular gaskets 34, which are located on the side of the mounting block 33 away from the filter housing 1. A spring 35 abuts between the two gaskets 34 and the spring 35 is sleeved on the screw 32. A nut 36 is also threadedly connected to the screw 32, and the nut 36 abuts on the side of the gasket 34 away from the spring 35, so as to press the static friction disc 22 on the filter housing.

[0034] A plurality of sight gauges 12 are also vertically fixed to the side wall of the filter housing. In this embodiment, there are four sight gauges 12 distributed around the static friction disk 22. When the clamping device needs to adjust the gap, the sight gauges 12 can quickly observe the gap distance, thereby achieving fast and accurate adjustment.

[0035] The position of the fixing block 31 on the filter housing is adjustable. A plurality of slots 13 are fixed to the filter housing. The number of slots 13 is the same as the number of fixing blocks 31 and they are arranged relative to each other. The length direction of the slots 13 is perpendicular to the axis of the central axis 11. The fixing block 31 is located in the slots 13 and can slide along the length direction of the slots 13. The side walls of the slots 13 are provided with a plurality of threaded holes 131 spaced apart. The threaded holes 131 are internally threaded with bolts 132. When the bolts 132 pass through the threaded holes 131 and abut against the fixing block 31, the position of the fixing block 31 is fixed. When it is necessary to install distribution heads 2 of different diameters, the position of the screw 32 is changed by adjusting the position of the fixing block 31, so that the clamping device can meet the clamping work of distribution heads 2 of different diameters.

[0036] An oil filling hole (not shown in the figure) is also provided on the static friction disc 22. By injecting grease into the oil filling hole, lubrication and sealing effects can be maintained between the static friction disc 22 and the filter housing 1.

[0037] The implementation principle of the spring clamping device for a vertical disk dispensing head according to the present embodiment is as follows: when installing the clamping mechanism 3, the position of the fixing block 31 is adjusted to fit the diameter of the dispensing head 2. Then, after the screw 32 is inserted through the mounting block 33, the gasket 34 and spring 35 are installed in sequence. After the appropriate gap is achieved by observing the sight gauge 12, the nut 36 is rotated to press against the gasket 34 to ensure the fixed position. The clamping mechanism 3 facilitates adjustment and maintenance of the clearance around the dispensing head 2. The spring 35 also provides a buffer for the static friction disk 22, reducing operational wear of the static friction disk 22 and minimizing material leakage.

[0038] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this application shall be determined by the appended claims.
