Abstract

The utility model discloses a filter unit which is especially suitable for the filtering process of the sugar industry. The device is fixedly connected with an input tube at the upper part of the closed strainer. The middle part is fixedly provided with a filter screen, and the inner side of the filter screen is provided with a brush which can be connected to a whole with a draw rod of an air cylinder. The lower part of the strainer is fixedly connected with a pot for storing slag. The strainer is fixedly connected with the upper part of a cyclone by an output tube whose lower part is in fixing connection. The lower end of the cyclone is fixedly connected with a slag storage arrester by a valve. The upper end and the lower end of the slag storage arrester are respectively and fixedly connected with the valve. The device with simpler structure is particularly suitable for the filtering process of the sugar industry.

Description

A kind of filter

The utility model relates to the brewing industry field, refers more particularly to a kind of device of filtration art.

In filtering technique, especially in the production process of sugar industry, filter a most important link that becomes the development of the restriction industry at present.For a long time, the filter type of filter press technique fails to change always, and syrup filters through filter cloth under certain pressure, and it is low to exist efficient, loses big shortcoming.When syrup hammer degree reaches certain numerical value, factor such as it is poor that the filter type of filter press technique exists filter quality again, and productive labor intensity is big, thereby the filtration of sugar industry becomes a problem that needs to be resolved hurrily.

The purpose of this utility model is the deficiency that is to alleviate prior art, and provides a kind of under the prerequisite of ensuring the quality of products, and alleviates worker's labour intensity and raises labour efficiency the filter that reduces production costs.

This practical purpose is to realize like this, a kind of filter, mainly form by coarse filter, cyclone, storage slag device, pipeline and valve etc., its special character is that airtight coarse filter top is connected with input pipe, is fixed with filter screen in the middle part and the filter screen inboard is provided with the brush that is connected as a single entity with air cylinder tie rod; The coarse filter bottom is connected with storage slag ladle body and valve; Coarse filter is affixed with the top of cyclone by the affixed efferent duct in bottom, and the lower end of cyclone is affixed with storage slag device by valve, and the top and the lower end of storing the slag device are connected with valve respectively.

Compared with the prior art the utility model has following good effect: one has improved efficiency owing to take the mechanical type filter to solve filter cloth filter type in the past prior art, has alleviated worker's labour intensity.It two is that filter screen takes different apertures to change the general layout in the single aperture of filter cloth in the past, both ensures the quality of products, and carries out different filtration interlayers again, has improved the rate of filtration; It three is that single filter cloth filter type by the past changes cyclone filter mode after the first coarse filtration into, and reliable quality assurance condition is arranged, and guarantees its product quality easily, improves syrup hammer degree.

Describe the embodiment and the concrete structure of a kind of filter of the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of a kind of filter of the utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

A kind of filter mainly is by coarse filter, and cyclone, storage slag device are formed the filtration main body, serve as the tie that connects each one to import, to go out pipeline, to finish the purpose of filtration.Its device mainly contains coarse filter (as shown in Figure 2), cylinder 1 usefulness screw is anchored on the coarse filter loam cake 19, and one reinstate bolt and be fixedly connected with coarse filter cylindrical shell 18, and the edge of disc brush body 16 along the circumferential direction is processed with dovetail groove, and is embedded with the hairbrush that adapts with it admittedly; Filter screen 4 is tubular by flat soil weld, and its Surface Machining has several apertures, and its aperture size is ascending, upwards arranges from filter screen 4 lower ends, is the intensity that guarantees filter screen 4, can be in the outside of filter screen 4 cage skeleton 20 in addition; Filter screen 4, cage skeleton 20 are welded as a whole with coarse filter base plate 21.The storage slag ladle body 14 that is reverse taper is welded as a whole with coarse filter cylindrical shell 18, and connects a valve 15 in its lower end with flange plate structure; The top of coarse filter cylindrical shell 18 is processed with a through hole and is welded with an input pipe 3, and the bottom also is processed with a through hole and is welded with an efferent duct 13 and is welded as a whole by pipeline and cyclone 7 tangential input pipes 5; The upper end of cyclone 7 cylinders is welded with core pipe 6, and the lower end is welded with the storage slag ladle body 8 that is reverse taper, and weld by the valve 9 and the upper end of storage slag device 10 lower end, and the top and the lower end of storage slag device are welded with valve 11 and valve 12 respectively.More than constitute static structure of the present utility model.

When being used for the syrup separation circuit, syrup under certain pressure in input pipe 3 enters the filter screen 4 of coarse filter, stay filter screen 4 inboards through particle, impurity that filter screen 4 will be bigger, and be deposited in the storage slag ladle body 14 that is reverse taper, will drive brush 16 by air cylinder tie rod 2 by the cylinder 1 of time opening it will be pushed in the storage slag ladle body 14 particle, the impurity that adheres to filter screen 4 inboards; Through the syrup after the coarse filtration between filter screen 4 and cylindrical shell 18, tangential input pipe 5 through efferent duct 13 and pipeline, cyclone 7 tangentially is input in the cyclone 7, and the rotation at a high speed of generation under pressure, this moment is under centrifugal action, impurity drops in the storage slag ladle body 8 that is reverse taper through the inwall of cyclone 7, and the valve through opening 9 continues to be deposited among the storage slag device 10.The syrup of cyclone 7 centers flows out into subsequent processing through core pipe 6.Tapping process is a valve-off 9, opens wash water valve 11 and residual cake valve 12, and impurity flows out voluntarily through residual cake valve 12 under the pressure of water, and valve-off 11, valve 12 were opened valve 9 and got final product after deslagging finished, and tapping process does not influence the operate as normal of cyclone 7.
