Description

Technical Field

[0001] The utility model belongs to the technical field related to leaf filter collection devices, and specifically relates to a novel annular collection device for a leaf filter. Background Art

[0002] The intelligent pressurized fine filter is a type of filtration equipment that can be widely used in fine filtration operation units. The equipment is mainly used in chemical industries such as sugar production, alumina, and vanadium extraction from steel slag. It has a high degree of automation, good filtrate indicators, and low operating costs. It is currently the most advanced equipment for solution fine filtration units in the world. Its working principle is that the raw liquid enters the main cylinder of the equipment through the feed pump. Under the action of pressure, it passes through the filter cloth and filter elements. There is a circle of elbow components, manual butterfly valves, and liquid collection tanks on the outer periphery. In the first few minutes, unqualified liquid circulates to allow the filter cloth to hang a layer of filter cake. Qualified liquid flows to the high-level tank. At the end of the filtration, the high-level tank buffers the liquid and self-cleans the filter cloth, filter cake and other filter elements. The pressurized fine filters currently on the market have larger main cylinder diameters and filtration areas. The main cylinder diameter has reached 4.5 meters, and the outer liquid collection tank has a maximum diameter of 5.708 meters. The number of elbow components and manual butterfly valves evenly distributed around the circumference of the cylinder has reached 80. The structural diagram is attached. Figure 6 The existing outer sump components are large in size, have high transportation costs, and are relatively complex in structure, requiring secondary on-site assembly, resulting in high equipment manufacturing and installation costs.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0025] like Figures 1 to 6As shown, a new annular collecting device of a leaf filter is provided, a main tank body 1 of the leaf filter and a liquid storage tank 4. An annular collecting structure 3 is provided on the upper part of the main tank body 1 of the leaf filter, and an upper head 2 is connected above the annular collecting structure 3. The upper head 2 and the annular collecting structure 3 are locked and connected by a fixed lock 7. The annular collecting structure 3 includes a connecting cylinder 8 and an external annular structure 9. The upper end of the connecting cylinder 8 is fixedly provided with a matching connecting ring 12 by welding, and the lower end of the connecting cylinder 8 is fixedly connected to the main tank body 1 of the leaf filter by welding. An external annular structure 9 is welded on the outer side of the connecting cylinder 8. The external annular structure 9 and the connecting cylinder 8 are eccentric structures. A plurality of through holes 14 are evenly distributed in the circumferential direction on the outer wall of the connecting cylinder 8. A side connecting head 10 is connected to the side of the external annular structure 9 close to the liquid storage tank 4. The side connecting head 10 is connected to the liquid storage tank 4 through a liquid guide pipe 5 for supplying the liquid in the liquid storage tank 4 to the annular collecting structure 3.

[0026] Among them, the cross-section of the external annular structure 9 is a right-angled trapezoidal structure, the bottom surface of the external annular structure 9 is an inclined structure design, and the side connector 10 is located on the lower end side of the inclined structure to buffer the liquid inlet pressure of the side connector 10.

[0027] The eccentric direction of the outer annular structure 9 is close to the end of the side connector 10 , so that the liquid can balance the water pressure during the flow in the inner cavity between the outer annular structure 9 and the connecting cylinder 8 .

[0028] A card slot structure that is compatible with the fixed lock buckle 7 is opened at the lower outer side of the mating connecting ring 12, and a sealing groove 13 is opened on the upper end surface of the mating connecting ring 12. A sealing ring is installed in the sealing groove 13 to ensure the sealing of the mating connection between the upper head 2 and the mating connecting ring 12.

[0029] The lower end of the liquid-conducting pipe 5 is provided with a catheter connecting flange 6, and the end position of the side connector 10 is provided with a joint connecting flange 11. The catheter connecting flange 6 and the joint connecting flange 11 are fixedly connected by bolts and nuts, and a sealing gasket is provided at the connection position to ensure the sealing of the connection.

[0030] The outer side of the leaf filter main tank 1 and the outer side of the liquid storage tank 4 are fixedly provided with a support seat 15 to cooperate with the support frame structure to achieve the fixation of the device position.

[0031] The working principle of the utility model is as follows: the existing large-scale intelligent pressure fine filter has a main body cylinder of 4.5 meters and an external liquid collecting tank, using a steel pipe of φ509×9, a center distance of 5.2 meters, and a maximum outer diameter of 5.708 meters. The present application cancels the original liquid collecting tank, elbow assembly, and manual butterfly valve, and uses a welded structure instead, which is directly welded to the main tank body 1 of the leaf filter. After welding, the entire structure is heat treated and pressure tested, and no secondary assembly is required, thereby reducing leakage points during use without changing the filtration area of ​​the large-scale intelligent pressure fine filter. The outer diameter of the liquid collecting tank is reduced from 5.708 meters to 4.85 meters, which is convenient for transportation and saves costs.

[0032] The outer annular structure 9 is an eccentric structure, and the bottom surface is an inclined structure design. The storage space at the connection position with the side connector 10 is large, and the volume of the annular cavity in the direction of liquid flow gradually decreases, so that the water pressure of each through hole 14 connected to the interior of the main tank tends to be stable;

[0033] After the equipment is improved, the manufacturing and transportation costs of the equipment are reduced, the labor intensity of the installation workers is reduced, and secondary assembly is reduced. After the overall heat treatment of the equipment, it is less likely to deform and corrode due to alkali embrittlement, which extends the service life of the main engine cylinder. At the same time, because the cylinder has no leak points, it can improve the on-site environment and reduce the cost of cleaning the on-site environment.

[0034] The utility model adopts an annular collecting structure 3 to replace the original liquid collecting tank, elbow assembly, and manual butterfly valve to simplify the structure. At the same time, the annular collecting structure 3 and the main tank body 1 of the leaf filter are fixedly connected by welding, without the need for secondary assembly on site. The overall annealing is adopted to avoid deformation and alkali embrittlement corrosion during use. The maximum outer diameter size specification of the annular collecting structure 3 is reduced for easy transportation. The outer annular structure 9 of the annular collecting structure 3 is eccentric relative to the main tank body 1 of the leaf filter, and the bottom is designed as an inclined structure. Through holes 14 are evenly distributed on the outer wall of the connecting cylinder 8 to ensure the realization of the function of the annular collecting structure 3.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
