Description
Technical Field
The utility model relates to a compressor technical field, especially a compressor entry precision filter core.
Background
At present, most of filter elements at the inlet of a compressor are punching plate winding drums, stainless steel wire meshes are attached to the inside or the outside of the filter elements, the punching plate winding drums are used as supports, and the apertures of the stainless steel wire meshes are used for filtering and intercepting particles. Generally, when the gas passes through the stainless steel wire mesh, particles contained in the stainless steel wire mesh are intercepted, wherein the particles are smaller than the pore diameter of the wire mesh. When the cleanliness of a medium required by the inlet of the compressor is higher, the filter element with the structure cannot meet the requirement of high-precision filtration because only one layer of stainless steel wire mesh is used as a filter layer, and the strength of the stainless steel wire mesh is lower when the mesh number is higher, so that the stainless steel wire mesh cannot be welded with a punched plate cylinder. And, single-deck stainless steel net only surface area can hold dirt, does not have the three-dimensional dirt space of holding, and when the particulate matter in the unit area reached more than 50%, pressure differential will increase, need change the filter core this moment, has so greatly reduced the life of filter core.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that needs to solve provides a compressor entry precision filter core, does not change the size of filter core, improves filter fineness, extension filter core life.
In order to solve the technical problem, the utility model adopts the following technical proposal.
A compressor inlet precision filter cartridge comprising a stainless steel filter cartridge placed within a filter at the compressor inlet; a plurality of layers of rolled filter cotton for graded filtration are sequentially arranged in the filter cylinder from top to bottom, and a punching plate clapboard for separating the filter cotton is arranged between each layer of filter cotton; the bottom of the filter cylinder is welded with a punching plate bottom cover for supporting filter cotton, and the top of the filter cylinder is provided with a sealing ring for hermetically connecting a filter element air inlet and a filter air inlet; and a top wire mesh for intercepting suck-back filter cotton when the compressor is abnormally stopped is welded on the inner wall of the filter cylinder below the sealing ring.
Above-mentioned compressor entry precision filter core, the precision of crossing the filter pulp from top to bottom gradually thins.
The thickness of the first layer of filter cotton positioned below the top end silk screen of the compressor inlet precise filter element is one third of that of the lower layer of filter cotton.
Due to the adoption of the technical scheme, the utility model has the following technical progress.
The utility model discloses a indulge form air guide structure, make gaseous filtration step by step through straining the filter pulp of section of thick bamboo inside, not only have good filtering quality, have good appearance dirt space again for the filter core not only satisfies the filtration requirement of high accuracy, can also prolong the life of filter core. The utility model discloses strain inside filter pulp of a section of thick bamboo and adopt the layering setting, can use a period at the filter core and independently demolish the change, reduced the maintenance cost.

wherein: 1. the filter comprises a sealing ring, a filter cylinder 2, filter cotton 3, a punching plate partition plate 4, a punching plate bottom cover 5 and a top end wire mesh 6.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The compressor inlet precision filter element is structurally shown in figures 1-3 and comprises a sealing ring 1, a filter cartridge 2, filter cotton 3, a perforated plate partition plate 4, a perforated plate bottom cover 5 and a top end wire mesh 6. The filter cartridge 2 is placed inside the filter at the inlet of the compressor, and the gasket 1 is disposed on the top of the filter cartridge 2 to sealingly connect the inlet of the filter element to the inlet of the filter. The filter cotton 3 is divided into five layers and is arranged inside the filter cylinder 2 for filtering. The perforated plate partition plate 4 is arranged in the middle of each layer of filter cotton 3 and used for separating the filter cotton 3. A perforated plate bottom cover 5 is welded to the bottom of the filter cartridge 2 for supporting the filter pulp 3. The top end silk screen 6 is welded on the inner wall of the filter cylinder 2 below the sealing ring 1 and is used for intercepting the suck-back filter cotton 3 when the compressor is abnormally shut down.
The filter cartridge 2 is a shell of a filter element and is formed by welding stainless steel plate winding drums according to the size of a filter at the inlet of a compressor. The filter cotton 3 is roll-shaped filter cotton and is divided into five layers to be placed in the filter cylinder 2, and the middle of the filter cotton is separated by a stainless steel punched plate partition plate 4 to ensure the strength of the filter cotton. Five layers of filter pulp 3 divide into the triplex according to the precision difference, and filter pulp's precision from top to bottom gradually thins, the first portion: the first and second layers are pre-filtering layers with thicker precision, are used for blocking larger particles, and are characterized by large flow and thick pore diameter, so that the large particles are prevented from entering the second part of the primary filtering layer, and the service life of the second part of the filtering layer is prolonged; a second part: the third and fourth filter layers are primary filter layers with moderate precision and mainly intercept moderate particulate matters, and are characterized by moderate flow and moderate pore size, so that the moderate particulate matters are prevented from entering the third filter layer, and the service life of the third filter layer is prolonged; and a third part: for the fifth layer, the process requires precision, and because of the interception of the first two parts, the third part of the filter layer only needs to intercept smaller particles. The three filter layers gradually increase the precision, so that the requirement of high precision can be met, and the service life of the filter element is prolonged. Because the filterable precision of first layer is coarser, and the particulate matter is bigger, and in order to facilitate the filtration, the thickness of first layer filter pulp is the third of lower floor's filter pulp thickness.
The filter cotton adopts the layering setting, when the particulate matter in the filter cotton unit area reaches a certain amount, can demolish the filter core alone and change, has reduced the maintenance cost.
The bottom cover 5 of the perforated plate is used as a bottom support and is welded on the edge of the filter cartridge 2, and the filtered clean gas medium passes through the holes.
The top wire 6 is welded to the cartridge 2 and in case of back suction which may occur when the system is not normally stopped, the top wire 6 acts as a catch to avoid sucking the upstream line.
The sealing ring 1 is arranged at the top of the filter cylinder 2, so that the air inlet of the filter element is connected with the air inlet of the filter and sealed, and all gas media can pass through the filter element.
The utility model discloses the upper end of straining a section of thick bamboo in is gas inlet, and gas is straining inside from top to bottom and is carrying out the stage filtration, and the clean gas after the process filtration passes through in the bottom of straining a section of thick bamboo, because the filter fineness of crossing the filter pulp from top to bottom progressively thins, has consequently increased gaseous filter fineness. The utility model discloses well filter pulp adopts and indulges form air guide structure, not only has good filtering quality, has good appearance dirt space again and can prolong the life of filter core.
