Technical Field
The invention relates to the field of auxiliary mounting equipment of a disc filter, in particular to a fixed ring for mounting a filter plate of the disc filter.
Background
The disc filter can be applied to all industries capable of utilizing vacuum filtration, and is widely applied to the solid-liquid separation of aluminum hydroxide seed liquid, salt discharge liquid, bauxite flotation concentrate, flotation concentrate of various mines, tailings and coal slime in coal industry in alumina plants in the non-ferrous metal industry.
The filter disc of the disc filter rotates in a filter tank filled with slurry, materials are adsorbed under the action of vacuum, filtrate flows away through an internal flow channel, and solids are prevented from forming a filter cake by filter cloth, so that the aim of solid-liquid separation is fulfilled. The filter disc is the main part of the disc filter and is formed by splicing a sector filter plate, the root of the sector filter plate is fixed on a central shaft, and the outer edge of the sector filter plate is connected by a group of guide rails to form a complete ring to fix the excircle of all the filter plates. In order to ensure the stable operation of the equipment, the flatness of the disc surface of the filter disc formed by the plate surfaces of all the filter plates is particularly important when the equipment is installed.
The root installation forms of the filter plate of the traditional disc filter mainly comprise two types, one type adopts an S-hook-like form, and the root of the filter plate is tightly pressed on the plane of the support sleeve by bolts at two sides; the other form is that the root part of the filter plate is connected with the main shaft through a sealing rubber sleeve, and the upper part of the filter plate is tensioned through a pull rod to tighten the guide rail so as to fix the excircle of the filter plate. The first mode is pressed tightly through the bolts on two sides, the root is stably installed, but due to the support of the sealing ring, the pretightening force of the bolts on two sides is different, the sector plate is easy to deflect during installation, and two nuts need to be screwed correspondingly by one filter plate, so that the installation is troublesome. Although the second mode is simple to install, the tightness of connection between the sealing rubber sleeve and the main shaft is poor, and vacuum leakage or filtrate entering into the flow channel is easy to occur. The guide rail is only compressed and fixed through the pull rod, the deflection is easy, and the installation stability of the root part is poor.
Disclosure of Invention
The invention aims to provide a fixed ring for mounting a filter plate of a disc filter, which ensures the flatness of a filter disc formed after the filter plate is mounted, and can seal the root of the filter plate to avoid vacuum leakage.
In order to solve the technical problems, the invention adopts the technical scheme that: the utility model provides a fixed ring of installation disc filter plate, includes the ring body and is used for fixing the coupling assembling of ring body on the filter main shaft, and the ring body includes two side ring boards that are parallel to each other, and the face of two side ring boards distributes relatively, and the interval is equipped with a plurality of baffles in the annular gap between two piece side ring boards, and the root that lies in between arbitrary two adjacent baffles in the annular gap all forms and supplies a filter plate pegs graft in the epaxial slot of filter main shaft.
Preferably, the connecting assembly is a connecting plate arranged at the inner edge of the side ring plate, one end of the connecting plate is welded and fixed at the inner edge of the side ring plate, and the other end of the connecting plate is fixedly connected with the main shaft of the filter in a welding mode.
Preferably, the connecting plate is arranged on the side ring plate at a position corresponding to the partition plate.
Preferably, the two side ring plates in the ring body are concentrically distributed on the main shaft of the filter.
Preferably, a plurality of partition plates are uniformly arranged in the annular gap between the two side annular plates at intervals.
Advantageous effects
The ring body is fixed on a main shaft of the filter through a connecting component, and two side ring plates are divided into a plurality of slots for inserting filter plates by partition plates in the ring body. After the root of the filter plate is fixed on the main shaft of the filter through the slot, two sides of the root of the filter plate are respectively pressed through the side ring plates, so that the flatness of the disc surface of a filter disc consisting of the filter plates is ensured; the periphery of the root part of the filter plate is respectively supported by a side annular plate and two partition plates to form an annular surface, so that the stability of the filter plate is greatly improved compared with the installation mode in the prior art; the periphery of the root part of the filter plate is compressed and sealed by the side ring plate and the partition plate, so that the root part of the single filter plate has good sealing performance and no vacuum leakage.
