Abstract
The utility model relates to filters, in particular to a dust filter. The dust filter comprises a coal injection filter main body and a press cover sealing the filter main body through a press strip and a compression bolt. The dust filter is characterized in that the filter main body is provided with at least two pipe mouths and filter devices, wherein the pipe mouths are symmetrical to each other and communicated with pipelines, and the filter devices are arranged on the pipe mouths. The dust filter not only resolves the problems that an existing dust filter does not have a decompression measure before clearing, but also avoids the condition that the gage pressure is too large to enable a seal pad to be damaged in sprayed mode, and improves working efficiency simultaneously.
Description
Technical field
The utility model relates to filter, relates in particular to a kind of dust filter unit.
Background technology
Dust filter unit is the common equipment of foreign material in the filtering dust, generally be installed on the winding-up pipeline, by filter screen with the bulk foreign matter from, prevent line clogging, dust is carried unblocked, guarantee the continous-stable coal powder injection.
Existing dust filter unit often because of the in time row pressure of course of work middle filtrator, causes filter leak, and is light then destroy the work quality of filter, heavy then endanger user's health, and environment is also caused no small destruction.
The utility model content
The purpose of this utility model be for solve existing dust filter unit before cleaning without pressure-relief measure, and pressure bad sealing gasket of excessive spray and the technical problem of leaking gas, a kind of dust filter unit is provided, its reasonable in design, improve operating efficiency, also greatly ensured personal safety and Environmental security.
To achieve these goals, the utility model can be taked following technical scheme:
A kind of dust filter unit, the gland that it comprises the coal powder injection filter body and seals described filter body by press strip and hold-down bolt, it is characterized in that, described filter body is provided with the mouth of pipe of at least two symmetrical connecting pipes and is located at the filter at every described mouth of pipe place.
In preferred embodiment of the utility model, dust filter unit comprises that further another mouth of pipe of every described pipeline is the flange connector.
In preferred embodiment of the utility model, dust filter unit further comprise described filter be in screen pack, filter bag, the filter any.
In preferred embodiment of the utility model, the bottom that dust filter unit further is included in described filter body also is provided with blowdown apparatus, and described blowdown apparatus comprises blow-off pipe and the blowoff valve of being located on the blow-off pipe.
In preferred embodiment of the utility model, dust filter unit comprises that further described gland is provided with pressure discharge device, and described pressure discharge device comprises discharge pressure pipe and the purge valve of being located on the discharge pressure pipe.
In preferred embodiment of the utility model, dust filter unit further comprises and also is provided with sealing gasket between described filter body and gland.
The beneficial effects of the utility model are: dust filter unit of the present utility model, adopted the mouth of pipe and the filter of being located at every mouth of pipe place that are provided with at least two symmetrical connecting pipes at filter body.The utility model not only solved existing dust filter unit before cleaning without pressure-relief measure, also avoided pressure bad sealing gasket of excessive spray and the situation of leaking gas, simultaneously, improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of preferred embodiment 1 of the present utility model;
Fig. 2 is the structural representation of preferred embodiment 2 of the present utility model;
Fig. 3 is the structural representation of preferred embodiment 3 of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
Such as Fig. 1, Fig. 2, shown in Figure 3, the gland 2 that it comprises coal powder injection filter body 1 and seals described filter body 1 by press strip and hold-down bolt 9, described filter body 1 is provided with the mouth of pipe a of at least two symmetrical connecting pipes 3 and is located at the filter 4 at every described mouth of pipe a place, and another mouth of pipe b of every described pipeline 3 is flange connectors.
Dust filter unit is in the situation that normal operation, dust to be separated and foreign material are in the mouth of pipe a of pipeline 3 is passed into the main body 1 of filter, pass through again the filtration of filter and delete choosing, isolated foreign material are discharged through blow-off pipe 5, simultaneously, pressure discharge device on the filter body 1 starts, when experiencing under the certain pressure, open purge valve 8, purpose is in order to allow filter body 1 interior pressure work under the pressure of normal operation, the situation of having avoided like this pressure bad sealing gasket of excessive spray and having leaked gas simultaneously, has improved operating efficiency.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine technical scope according to the claim scope.
