Abstract
The utility model relates to an iron drying filter of refrigerating device such as refrigerator, air-conditioner and etc, belonging to a technical field of refrigerating equipment fitting. The utility model comprises an iron cylinder, and a filter mesh, a molecule sieve and a copper cap. The filter mesh, the molecule sieve and the copper cap are arranged in the iron cylinder in order along the axis line of the iron cylinder, one end of the cylinder adjacent to the filter mesh is an outlet end and the other end of the cylinder is an inlet end, the outer wall of the said cylinder is provided with a paint coating. The utility model has good anti-corrosion and anti-rust performance, and can reduce the production cost of drying filter effectively, solve the problem that in the prior art the drying filter is difficult to meet the high anti-corrosion and anti-rust performance of refrigerating equipment.
Description
Technical field
The utility model relates to a kind of iron drierfilter that is used for refrigeration plants such as refrigerator and air conditioner, belongs to the technical field of refrigeration plant accessory.
Technical background
Because copper material itself has good antiseptic and rustproof performance, therefore in to the higher refrigeration industry of antiseptic and rustproof performance requirement, copper material is widely used in the accessory manufacturing of refrigeration plant.But because the price of copper material itself is higher, moreover along with the day of the energy is becoming tight, also when the river rises the boat goes up for the price of copper material, caused the manufacturing cost of refrigeration plant significantly to rise.
In order to reduce the cost of refrigeration plant accessory, someone has proposed a kind of one-way iron drying filter by name (patent No.: patent application CN200510049991.3), connect entrance sleeve and discharge connection at irony body two ends and constitute the one-way flow structure, in body, maintain molecular sieve desiccant; Be provided with preposition filter block and backstop between described molecular sieve desiccant and the entrance sleeve.Above-mentioned patent application has reduced the production cost of device for drying and filtering to a certain extent, but because its inborn defective of iron material is antiseptic and rustproof poor-performing, do not see that above-mentioned patent application document does antiseptic and rustproof processing to device for drying and filtering, therefore, the disclosed device for drying and filtering of above-mentioned patent application probably is difficult to satisfy the higher antiseptic and rustproof performance requirement of refrigeration plant.
Summary of the invention
The utility model purpose is to provide a kind of good antiseptic and rustproof performance that possesses, and effectively reduce the iron drierfilter of the production cost of device for drying and filtering, what solved that the prior art iron drierfilter exists is difficult to satisfy the higher antiseptic and rustproof problems such as performance requirement of refrigeration plant.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise iron cylindrical shell and be successively set on screen pack, molecular sieve and copper cap in the cylindrical shell along the tubular axis direction, the end that cylindrical shell and screen pack are adjacent is the port of export, the cylindrical shell other end is an entrance point, and described cylinder body outer wall is provided with enamelled coating.The utility model is provided with enamelled coating to the outer wall of the iron cylindrical shell of device for drying and filtering, can with cylinder body outer wall and air or other gas and water resistance every, effectively improved the antiseptic and rustproof performance of cylindrical shell, reach the equal antiseptic and rustproof performance of the dried filter of copper, and effectively reduced the production cost of device for drying and filtering.
As preferably, described enamelled coating setting and the outer wall of cylindrical shell except that reducing.Reducing place is not sprayed paint, in case the enamelled coating of whole device for drying and filtering the time is burnt in welding, influences the appearance rust-proof effect.
As preferably, described cylindrical shell is made of the steel pipe that the steel band ratio-frequency welding is connected into.The steel band upper and lower surface is all comparatively bright and clean, therefore, adopts steel band to make the fineness that can improve the cylindrical shell inside and outside wall device for drying and filtering, improves the antiseptic and rustproof performance of tube, and reduces the flow resistance of cylinder inboard wall to refrigerant simultaneously, reduces the energy consumption of refrigeration plant.
As preferably, the inwall of described cylindrical shell and screen pack adjacent is provided with internal projecting ring, and the internal diameter of described internal projecting ring is less than the external diameter of screen pack.Because what screen pack and workpiece adopted is loose fit, so the internal projecting ring of cylinder inboard wall can stop moving axially of screen pack effectively, guarantees that device for drying and filtering plays good dry filter effect.
Therefore, the utlity model has good antiseptic and rustproof performance, and effectively reduce the characteristics such as production cost of device for drying and filtering.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, device for drying and filtering comprises the iron cylindrical shell 3 of reducing 1 with two ends and reducing 2 and is successively set on screen pack 4, molecular sieve 5 and copper cap 6 in the cylindrical shell along the tubular axis direction, cylindrical shell 3 is provided with internal projecting ring 7 with the inwall of screen pack 4 adjacents, the internal diameter of described internal projecting ring is less than the external diameter of screen pack, cylindrical shell is made of the steel pipe that the steel band ratio-frequency welding is connected into, the 4 adjacent end reducings 2 of cylindrical shell 3 and screen pack are the port of export, cylindrical shell 3 other end reducings 1 are entrance point, and the outer wall of cylindrical shell except that the reducing at two ends is provided with enamelled coating 8.
