AI Technical Summary
The existing candle filters use a large amount of air when they are blown, resulting in an increase in cost. How to improve the efficiency of air when the amount of air is reduced has become a technical challenge.
A filter tube including uniform filter holes is designed. There are more than two baffles distributed in the axial direction in the filter tube. The central aperture of the baffle gradually increases from top to bottom, and the difference in the central aperture of the adjacent baffle also increases accordingly. The large, formed filtering component reduces gas loss and reduces gas consumption by changing gas pressure.
It effectively reduces the amount of gas used during regular blowing, while maintaining the blow-drying effect of the filter cake, saving energy and improving energy utilization.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of microporous filtration, and particularly relates to a candle-type filter element and a filter machine thereof. Background Art
[0002] In the industrial production process, microporous filters are widely used. The skeletons of the filter elements commonly used in candle filters on the market are generally divided into two types: circular cross-section and plum blossom cross-section. In order to increase the filtration area, plum blossom-shaped skeleton filter elements are usually widely used. After the filtration is completed, the filter cake needs to be blown dry and the filter cake needs to be recovered, that is, the gas positive blowing method is used to blow dry the liquid contained in the filter cake to ensure the filter cake thickness. However, the existing candle filter element consumes a large amount of gas during positive blowing, and a very large amount of gas needs to be provided to blow the filter cake dry. For larger filtering equipment, the cost also increases accordingly. How to improve the positive blowing efficiency while reducing the gas consumption has become a technical problem that needs to be solved at present. Utility Model Content
[0003] In view of the above-mentioned defects in the prior art, the purpose of the utility model is to provide a candle filter element and a filter machine thereof.
[0004] The purpose of this utility model will be achieved through the following technical solutions:
[0005] The candle filter element comprises a filter tube with filter holes evenly distributed, wherein two or more baffles are evenly distributed in the filter tube along the axial direction, a central hole is opened in the center of the baffle, and the aperture of the central hole increases from top to bottom.
[0006] Preferably, the diameter difference between the central holes of adjacent baffles increases from top to bottom.
[0007] Preferably, the filter assembly comprises a central tube and a filter tube arranged outside the central tube, the upper and lower ends of the filter assembly are both provided with end caps, the end caps are provided with filter cloths, and the filter cloths are connected to the end caps through pressure caps.
[0008] Preferably, a gasket is provided between the end cover and the filter cloth.
[0009] Preferably, the cross section of the filter assembly is plum blossom-shaped.
[0010] A filter comprises a body and a candle filter element as described above and arranged in the body.
[0011] The outstanding effect of the utility model is that the filter assembly formed by the filter tube with a central hole baffle inside can effectively reduce the gas consumption during positive blowing without affecting the drying effect of the filter cake, effectively save energy, and has strong practicality.
[0012] The specific implementation methods of the utility model are further described below in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a schematic diagram of the filter tube structure of the utility model.
[0014] Figure 2 It is a schematic diagram of the filter element structure of the utility model. DETAILED DESCRIPTION
[0015] The utility model discloses a candle type filter element, combined with Figure 1-Figure 2 As shown, the filter element includes a filter tube 1 with filter holes evenly distributed, and two or more baffles are evenly distributed in the filter tube 1 along the axial direction. A center hole is opened in the center of the baffle, and the aperture of the center hole increases from top to bottom. In this embodiment, four baffles are provided, which are the first baffle 11, the second baffle 12, the third baffle 13 and the fourth baffle 14 from top to bottom. The first baffle 11, the second baffle 12, the third baffle 13 and the fourth baffle 14 are all provided with a center hole, and the aperture of the center hole on the first baffle 11, the second baffle 12, the third baffle 13 and the fourth baffle 14 is getting larger and larger.
[0016] Furthermore, the aperture difference between the center holes of adjacent baffles increases from top to bottom, that is, the aperture difference between the center holes on the first baffle 11 and the second baffle 12 is smaller than the aperture difference between the center holes on the third baffle 13 and the fourth baffle 14. The principle of setting the center holes of the baffles is that when gas enters from the outside of the filter cake, it enters different baffles in turn, and the change in the aperture size can change the gas pressure in the filter element, increase resistance, reduce gas loss, and thus reduce the overall gas consumption.
[0017] Furthermore, the filter element includes a central tube 5 and a filter assembly formed by a filter tube arranged outside the central tube 5, and the central tube 5 is used for the circulation of the filtered liquid. The cross section of the filter assembly is plum blossom-shaped. Of course, the cross section of the filter assembly can also be other shapes. The upper and lower ends of the filter assembly are both provided with end caps 2, and the end caps 2 are provided with filter cloth 4. The filter cloth 4 is connected to the end cap 2 through a gland 7, and the gland 7 is threadedly connected to the end cap 2. For the tightness of the connection, a gasket 6 is provided between the end cap 2 and the filter cloth 4. The filtering process is the same as that of the existing candle filter element, that is, the material to be filtered enters the filter tube, and the filtered liquid flows out through the central tube after filtration.
[0018] The utility model also discloses a filter, comprising a body, and a candle filter element as described above arranged in the body. The filter assembly formed by using a filter tube with a central hole baffle inside can effectively reduce the gas consumption during positive blowing without affecting the drying effect of the filter cake. It effectively saves energy and has strong practicality.
[0019] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
