Abstract

The utility model provides a diaphragm pump muffler, relates to pump body technical field, including casing, lid, and its characterized in that: casing, lid pass through the connecting piece to be connected in the junction casing inside wall cover is equipped with filter paper, and filter paper inner wall, lid inside wall overlap respectively and be equipped with the filter core, and the filter core cross -section becomes flute shape. Through adopting casing and the split type assembly of lid, but the washing is pulled down with the filter core to user's components of a whole that can function independently, and perhaps renew cartridge more uses repeatedly, has practiced thrift the cost. Filter paper is installed additional at the casing inside wall, better noise suppression effect can be played.

Description

A kind of membrane pump deafener

Technical field

This utility model relates to pump housing technical field, particularly to the noise reduction technology of a kind of membrane pump.

Background technology

Deafener is to stop sound transmission and a kind of device of allowing air-flow to pass through, is to eliminate air pertormance The important measures of noise.It is arranged on the deafener on membrane pump fluid passage and can effectively reduce noise.City The deafener commonly used on face is to be integral molding mostly, such as breathability after the overlong time that filter element uses Can be bad, filter element cleaning can only can not be changed, the increase that cost is covert.

Utility model content

Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that a kind of every Membrane pump deafener.

Technical problem to be solved in the utility model uses following technical scheme to realize:

A kind of membrane pump deafener, including housing, lid, described shell one end opening, the other end and circle Cylinder is fixing to be connected, and described cylindrical hollow also extends to enclosure interior, and cylindrical sides has external screw thread, It is connected with membrane pump by external screw thread.Described lid one end open, the other end is closed.Described housing, lid Body is cylindricality, and cross section is circular or rectangle.Described housing, lid are connected by connector in junction, Connector can be to snap connection or threaded.

Being set with filter paper, described filter paper one end open at described case inside wall, the other end is closed, and closes End cap lives cylindrical hollow part, on the one hand plays first sound deadening, on the other hand can be effective Prevent foreign material to be partially in housing by cylindrical hollow, divide in described filter paper inwall, lid medial wall Not being set with filter element, filter element cross section becomes corrugated.Separated with lid by housing, filter element can be torn open Under be carried out or change.

Further, it is connected end suit packing ring at described housing with cylinder, this acoustic filter and barrier film can be made Pump connects the tightst, and soundproof effect is more preferable.

The beneficial effects of the utility model are: by using housing and the split type assembling of lid, user can divide Filter element is pulled down cleaning by body, or changes filter element, Reusability, has saved cost.At case inside wall Install filter paper additional, it is possible to play more preferable soundproof effect.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and be prone to bright with effect White understanding, below in conjunction with being specifically illustrating, is expanded on further this utility model.

As shown in Figure 1, 2, a kind of membrane pump deafener, including housing 1, lid 2, housing 1 one end open, The other end is fixing with cylinder 6 to be connected, and cylinder 6 hollow also extends to housing 1 inside, cylinder 6 side There is external screw thread 7, be connected with membrane pump by external screw thread 7.Lid 2 one end open, the other end is closed.Housing 1, lid 2 is cylindricality, and cross section is circular or rectangle.Housing 1, lid 2 pass through connector in junction 9 Connecting, connector can be to snap connection or threaded.

Be set with filter paper 3, filter paper 3 one end open in housing 1 medial wall, the other end is closed, and blind end covers Cylinder 6 hollow space, on the one hand plays first sound deadening, on the other hand can effectively prevent miscellaneous Thing is entered in housing 1 by cylinder 6 hollow space, and in filter paper 3, housing 2 medial wall is respectively installed with Filter element 4, filter element 5, filter element 4, filter element 5 cross section become corrugated.Separated with lid 2 by housing 1, can So that filter element 4, filter element 5 are pulled down respectively and are carried out or change.

Further, it is connected end suit packing ring 8 at housing 1 with cylinder 6, this acoustic filter and membrane pump can be made Connecting the tightst, soundproof effect is more preferable.

Of the present utility model ultimate principle and principal character and of the present utility model excellent have more than been shown and described Point.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-mentioned Principle of the present utility model is simply described, without departing from this utility model described in embodiment and description On the premise of spirit and scope, this utility model also has various changes and modifications, these changes and improvements In the range of both falling within claimed this utility model.This utility model claims scope by appended power Profit claim and equivalent thereof define.
