Abstract

The utility model relates to a filter, in particular to a backflush type filter which is applicable to treating petrochemical industry sewage, and comprises a filter cylinder body, a sewage inlet pipe, a filtering liquid output pipe, a waste discharge port, a filtering core, and a backflush device, wherein the sewage inlet pipe and the filtering liquid output pipe are communicated with the filter cylinder body; the waste discharge port is arranged at the bottom of the filter cylinder body; the filtering core is arranged in the filter cylinder body; the backflush device consists of a storage tank communicated with the filtering liquid output pipe, and a backflush pipe communicated with the storage tank; the output end of the backflush pipe is positioned above the filtering core; and a water pump is arranged on the backflush pipe. In the utility model, the backflush type filter is not required for stop operation so that cleaning on the filtering core can be automatically conducted, and the structure is simple, the installation and overhauling are convenient and the application range is wide.

Description

The backpulsing filter
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of backpulsing filter that petrochemical effluent is handled that is applicable to.
Background technology
At present, in oil, chemical industry, there is use " basket filter " to carry out sewage disposal.Basket filter by filtration barrel body and the sewage inlet pipe that is communicated with it, trash discharge mouth, cross filter core, filtrate discharge pipe, and control module is formed.But such equipment is not owing to be provided with the device that filtering core is cleaned, thereby have following defective:
One, maintenance capacity is big, needs at set intervals with manually cleaning;
Two, inconvenience need be pulled down filtering core during cleaning, and then installs;
When three, keeping in repair, damage filtering core easily, thereby cost improved:
Four, influence is produced, and usually needs to shut down filtering core is cleaned, thereby causes production efficiency low excessively.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of backpulsing filter, and this backpulsing filter can stop under the situation of filter work not needing, and utilizes the liquid after self filtering automatically the filter core of crossing of filter to be cleared up.
The technical scheme that realizes the utility model purpose is as follows:
The backpulsing filter, comprise filtration barrel body, the sewage inlet pipe that is communicated with filtration barrel body, filtrate output tube, be arranged on the trash discharge mouth of filtration barrel body bottom, and be arranged on the filter core of crossing in the filtration barrel body, also comprise recoiling device, this recoiling device comprises the storage tank that is communicated with filtrate output tube, the backwash tube that is communicated with storage tank, the output of backwash tube was positioned at the top of filter core, and described backwash tube is provided with water plug.
The output of described backwash tube is provided with nozzle, can clean crossing filter core integral body like this, can not stay the dead angle.
Described backpulsing filter also comprises the control module of controlling water plug.Described control module can be controlled water plug and draw water from storage tank at any time, cleans crossing filter core.
Adopt above-mentioned scheme, filtering tank is stored filtrate filtered, when needs are cleared up crossing filter core, starts water plug by control module the filtrate in the storage tank is pumped, and clean crossing filter core by backwash tube.The utility model does not need to shut down just and can clean crossing filter core automatically, and it is simple in structure, and the installation maintenance is convenient, is widely used.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1 is filtration barrel body, and 2 is sewage inlet pipe, and 3 is filtrate output tube, and 4 is the trash discharge mouth, and 5 was filter core, and 6 is storage tank, and 7 is backwash tube, and 8 is nozzle, and 9 is water plug, and 10 is control module.
The specific embodiment
As shown in Figure 1, the backpulsing filter, comprise filtration barrel body 1, the sewage inlet pipe 2 that is communicated with filtration barrel body 1, filtrate output tube 3 are arranged on the trash discharge mouth 4 of filtration barrel body bottom, and be arranged on and cross filter core 5 in the filtration barrel body 1, also comprise recoiling device, this recoiling device comprises the storage tank 6 that is communicated with filtrate output tube, the backwash tube 7 that is communicated with storage tank 6, the output of backwash tube 7 was positioned at the top of filter core 5, and backwash tube 7 is provided with water plug 9.The output of backwash tube 7 is provided with nozzle 8.The backpulsing filter also comprises the control module 10 of controlling water plug.
The course of work of the present utility model: sewage enters in the filtration barrel body from sewage inlet pipe, passed through filter element filtering, and flow out in the equipment of rolling off the production line by filtrate output tube, wherein the filtrate of flowing out from part from filtrate output tube flow into the storage tank and stores, when needs are cleared up crossing filter core, start water plug by control module the filtrate in the storage tank is pumped, and clean crossing filter core by backwash tube.

Claims (3)
