Description
Technical Field
The invention belongs to the technical field of microporous filtration, and particularly relates to a spiral filter element for a large-specific gravity product and application thereof.
Background
Microporous filtration is a membrane filtration separation technology which is the earliest developed and widely applied membrane separation technology. The microporous filter is used for separating particles of 0.02-10 pm, and the pressure required by the process is 0.07-0.2 MPa. Microfiltration can be used to retain particulates, bacteria, contaminants, etc. from both gas and liquid phases and is a necessary means in modern industry to ensure product quality. The existing filtration usually adopts microporous filtration, treats that filtrate filters through microporous filter core, but some products that proportion is great often because the unable fine attached of gravity leads to dropping in the filter bottom at filter in filtering process for filter thoroughly.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides a spiral filter element for a product with a large specific gravity and application thereof.
The purpose of the invention is realized by the following technical scheme:
the spiral filter element comprises a hollow cylindrical filter element body, wherein a thread bulge is arranged on the surface of the filter element body, a groove is formed in the thread bulge along the axis of the filter element body, and the cross section of the filter element body is plum blossom-shaped.
Preferably, the filter element body overcoat is equipped with the filter cloth, the both ends of filter element body are provided with upper and lower head respectively, the both ends of filter cloth respectively through upper and lower head with the filter element body is fixed.
Preferably, the two ends of the filter element body are provided with pressing covers through threaded connection, the filter cloth sleeves the pressing covers, and the two ends of the filter element body are in compression connection with the pressing covers through the upper sealing head and the lower sealing head.
Preferably, the upper and lower sealing heads are in threaded connection with the gland.
Preferably, a liquid collecting pipe is arranged in the filter element body.
Preferably, the filter element body is provided with a plurality of end parts which are adjacent to each other and are in threaded connection.
Preferably, the surface of the filter element body is provided with a through hole, and the through hole is formed in the bottom of the groove.
Preferably, a filter is provided with the spiral filter element as described in any of the above.
The invention has the beneficial effects that: the filter element can effectively and thoroughly filter products with large specific gravity, and has good filtering effect. The spiral filter element also enhances the overall strength of the filter element, and the stability hidden trouble of filtration caused by a large-specific gravity product is not easy to occur.

Detailed Description
The technical scheme of the invention is specifically described below by combining with an embodiment, and the invention discloses a spiral filter element for a large-specific gravity product, which is shown in combined figures 1-3, and comprises a hollow cylindrical filter element body 1 similar to the existing filter element, wherein filter holes are uniformly distributed on the surface of the filter element body. The filter element comprises a filter element body 1 and is characterized in that a liquid collecting pipe 2 is arranged in the filter element body 1, filter cloth 3 is sleeved outside the filter element body 1, and an upper sealing head and a lower sealing head are respectively arranged at two ends of the filter element body 1. Specifically, threaded connection is passed through at the both ends of filter core body 1 and is provided with gland 4, upper cover 5 pass through the screw thread set up in outside gland 4, 3 covers of filter cloth are located outside gland 4, and both ends are through upper and lower head and gland compression joint, thereby make the both ends of filter cloth 3 respectively through upper and lower head with the filter core body is fixed. The upper and lower seal heads and the gland can be connected through threads.
The difference is, in order when filtering, the product of big proportion can block on 3 surfaces of filter cloth, prevents to drop in a large number, 1 surfaces of filter core body are provided with screw thread arch 11, just it has seted up recess 13 to open the axis along the filter core body on screw thread arch 11, observes along the axis direction of filter core body, the screw thread arch on filter core body and its surface is the plum blossom form. Gaps are arranged among the threads of each circle of layers, and the grooves 13 are further arranged, so that the filter cloth can be tightly coated on the surface of the filter element body during filtering. The number of the grooves 13 is generally 3-6, and the grooves are uniformly distributed on the periphery of the filter element body.
The filter element body 1 is provided with a plurality of filter element bodies, and the filter element bodies are adjacent to each other and are in end threaded connection. In the embodiment of the invention, two filter element bodies 1 are adopted, and the required number can be set according to different requirements.
With reference to fig. 4-6, the filter element 7 is applied in a filter 6 for products with large specific gravity, and the installation manner is the same as the prior art, and will not be described herein again. During filtering, the filtrate enters the filter element body through the filter cloth 3 and then is collected from a liquid collecting pipe in the filter element body 1 to obtain the filtrate. Because go up between circle screw thread arch and the lower circle screw thread arch gapped, and slotted 13's existence for the filter fluid of treating of big proportion can adsorb on the filter core surface during filtration, and the card is between the clearance, can be better more thorough filter.
When filtering the end, carry out gaseous blowback that gets into from the blowback of filter and carry out the filter core, gaseous from the inside toward blowing outward of filter core body, the filter cloth can be bloated, this moment, because the screw thread is protruding, the filter core can rotate when the blowback for the filtration product on filter cloth surface drops to the filter bottom very smoothly, carries out according to conventional flow at last that the filter residue drive can, accomplishes whole filtration.
There are, of course, many other specific embodiments of the invention and these are not to be considered as limiting. All technical solutions formed by using equivalent substitutions or equivalent transformations fall within the scope of the claimed invention.
