Abstract
The invention discloses a dry filter, which comprises a cylinder body, a front end cover, a rear end cover, a first filter screen, a second filter screen and a drying agent, wherein the cylinder body, the front end cover and the rear end cover are split, sealing copper flanges are arranged on the inner surfaces of two ends of the cylinder body, and the inner surfaces of the sealing copper flanges, which are embedded with the front end cover and the rear end cover, are reinforced through bolts and nuts; according to the invention, the front end cover and the rear end cover are connected with the cylinder body through the sealing cylinder flange, so that the sealing property of the connecting point can be improved, the front end cover and the rear end cover can be separated from the sealing copper flange by tightening the bolts and nuts, and the disassembly is convenient.
Description
Technical Field
The invention relates to the technical field of refrigeration, in particular to a drying filter.
Background
In a refrigerating apparatus, a dryer is installed as a filtering device between a condenser and a capillary tube of a refrigerating system, for drying a refrigerant flowing in a refrigerating pipe and filtering impurities in the system. Usually, the both ends of drier-filter adopt welded mode to carry out fixed connection usually in the use, if appear blockking up or damage the change difficulty behind the fixed connection, can only the whole piece change, it is inconvenient to use.
Chinese patent with prior art application No. CN201621333569.0 discloses a dry filter, which comprises a cylinder, a front end cover, a rear end cover, a first filter screen, a second filter screen and a desiccant; the front end cover and the rear end cover are clamped on the cylinder body, a hollow cavity is arranged in the cylinder body, the front end of the cylinder body is provided with an inlet, the rear end of the cylinder body is provided with an outlet, the inlet and the outlet are respectively used for being connected to a condenser and a capillary tube, a first filter screen and a second filter screen are respectively arranged at the two ends in the cylinder body, a drying agent is arranged between the first filter screen and the second filter screen, the front end cover is sleeved with a first sealing ladder clamping groove, the rear end cover is sleeved with a second sealing ladder clamping groove, in order to solve the problem, the front end cover and the rear end cover are detachably connected on the cylinder body, the drying agent can be conveniently replaced, the sealing stepped grooves are arranged on the front end cover and the rear end cover, the cylinder body is connected in a plugging mode instead of a traditional welding mode in the installation process, so that the drying filter can be recycled for many times.
According to the technical scheme, the front end cover and the rear end cover are clamped on the barrel body, so that the barrel body is difficult to disassemble and poor in sealing performance.
Disclosure of Invention
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a drying filter, the novel nipple rectifier comprises a cylindrical shel, the front end housing, the rear end cap, first filter screen, second filter screen and drier, the barrel is split type with front end housing and rear end cap, wherein the internal surface at barrel both ends is provided with sealed copper flange, inlay the internal surface of locating sealed copper flange with front end housing and rear end cap and consolidate through bolt and nut, the front end housing, the rear end cap passes through sealed cylinder flange and is connected with the barrel, can improve the leakproofness of tie point, and can the elasticity bolt and nut with front end housing and rear end cap and sealed copper flange separation, convenient dismantlement.
Further, the internal surface and the sealed copper flange threaded connection at barrel both ends to unable in time dismantlement after the bolt and nut corrosion, accessible dismantlement sealed copper flange separates front end housing, rear end cap and barrel.
The working principle is as follows: through end cover, rear end cap pass through sealed section of thick bamboo flange and be connected with the barrel, can improve the leakproofness of tie point, and can elasticity bolt and nut with front end cap and rear end cap and sealed copper flange separation, convenient dismantlement.
Drawings
FIG. 1 is a schematic cross-sectional view of the present invention.
In the figure: 1. a barrel; 2. a front end cover; 3. a rear end cap; 4. a first filter screen; 5. a second filter screen; 6. a desiccant; 7. and sealing the copper flange.
Detailed Description
The invention will be better understood from the following examples.
The structures, proportions, and dimensions shown in the drawings and described in the specification are for understanding and reading the present disclosure, and are not intended to limit the scope of the present disclosure, which is defined in the claims, and are not essential to the skilled in the art. In addition, the terms "upper", "lower", "front", "rear" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.
As shown in fig. 1, a drying filter, including barrel 1, front end housing 2, rear end housing 3, first filter screen 4, second filter screen 5 and drier 6, barrel 1 is split type with front end housing 2 and rear end housing 3, wherein the internal surface at barrel 1 both ends is provided with sealed copper flange 7, inlay the internal surface of locating sealed copper flange 7 with front end housing 2 and rear end housing 3 and consolidate through bolt and nut, front end housing, the rear end housing is connected with the barrel through sealed barrel flange, can improve the leakproofness of tie point, and can loosen bolt and nut with front end housing and rear end housing and sealed copper flange separation, convenient dismantlement.
Wherein, the internal surface and the 7 threaded connection of sealed copper flange at barrel 1 both ends to unable in time dismantlement after the bolt and nut corrosion, accessible dismantlement sealed copper flange separates front end housing, rear end cap and barrel.
