Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 5, the present invention provides a technical solution: the utility model provides a mining back flush filter, the on-line screen storage device comprises a base 1, base 1 is the ring structure, play and support the fixed action, the first dead lever 2 of higher authority fixedly connected with of base 1, the upper end fixedly connected with sewage collector 3 of first dead lever 2, play the effect of transfer sewage, fixedly connected with sewage valve 4 below the sewage collector 3, the break-make of control sewage, the fixed pipe 5 of outer wall fixedly connected with filter of sewage collector 3, be used for installing filter core 6, filter core 6 is installed to the inner wall of the fixed pipe 5 of filter, be used for filtering waste water, specifically, flange mounting is passed through in the fixed pipe 5 of filter at the both ends of filter core 6, the equal opening of the upper and lower extreme of filter core 6, and the upper end opening and the inlet tube 9 of filter core 6 switch on, the lower.

A speed reducer 7 is arranged at one end of the filter fixing pipe 5 far away from the sewage collector 3, a stainless steel brush holder 8 is arranged at the shaft end of the speed reducer 7 penetrating into the filter element 6, a water inlet pipe 9 is fixedly connected to the top wall of one end of the filter fixing pipe 5 far away from the sewage collector 3, a liquid inlet valve 10 is arranged in the middle of the water inlet pipe 9, a main water inlet device 11 is fixedly connected to one end of the water inlet pipe 9 far away from the filter fixing pipe 5, wastewater enters from the main water inlet device 11 and then enters the filter fixing pipe 5 from the water inlet pipe 9, a water outlet pipe 12 is fixedly connected to the bottom wall of one end of the filter fixing pipe 5 close to the sewage collector 3, the wastewater flows into the water outlet pipe 12 after being filtered by the filter element 6, a second fixing rod 13 is fixedly connected to the bottom wall of the sewage collector, the clear water filtered by all the filter elements 6 is gathered at the main water outlet 14, the main water outlet 14 is annular, and an opening is arranged at the bottom of the annular main water outlet 14 and used for discharging the clear water. In the filtering process, because the outside of filter fixed tube 5 is installed the pressure differential detector who detects filter core 6 inside and outside pressure differential, when detecting that one of them filter core 6 inside and outside pressure differential surpasss and predetermine the threshold value, send for the control box through the pressure differential changer, the speed reducer 7 of this filter core 6 of control box control starts, control sewage valve 4 is opened, feed liquor valve 10 is closed, waste water can flow in other filter core 6 this moment, consequently, do not need whole shut down, speed reducer 7 on that filter core 6 drives stainless steel brush yoke 8 and rotates this moment, stainless steel brush yoke 8 cleans the filth of filter core 6 inboard down, then these filths can be merged into the waste water that sewage collector 3 originally, after sewage valve 4 opens, these filths are discharged. In this way, during backwashing, all the filter elements 6 are not required to stop working, so that the production stop loss can be reduced, and compared with the existing filter with a single filter element 6, the design of a plurality of groups of filter elements 6 can bring greater efficiency and benefits.

Further, four are no less than to the quantity of first dead lever 2, and each first dead lever 2 all uses the centre of a circle of base 1 as central annular array, improve the fastness that base 1 and sewage collector 3 are fixed.

Furthermore, the number of the filter fixing pipes 5 is not less than four, and each filter fixing pipe 5 is arranged in an annular array by taking the circle center of the sewage collector 3 as the center, and a plurality of groups of filter elements 6 are arranged, so that greater efficiency and benefit can be brought, and even when one filter element 6 is backwashed, other filter elements 6 are not stopped, so that the loss can be reduced.

The working principle is as follows: when the mining backwashing filter is used, firstly, wastewater enters from the main water inlet device 11, then enters the filter fixing pipe 5 through the water inlet pipe 9, and is filtered by the filter element 6, clear water is discharged from the water outlet pipe 12, when the pressure difference detector detects that the pressure difference of the inner side and the outer side of one of the filter elements 6 exceeds a preset threshold value, the clear water is sent to the control box through the pressure difference transmitter, the control box controls the speed reducer 7 of the filter element 6 to be started, the sewage valve 4 is controlled to be opened, the liquid inlet valve 10 is closed, the wastewater can flow into other filter elements 6 at the moment, so that the whole machine halt is not needed, the speed reducer 7 on the filter element 6 drives the stainless steel brush holder 8 to rotate, the stainless steel brush holder 8 cleans dirt on the inner side of the filter element 6, then the dirt can be merged into the original wastewater of the sewage collector 3, and the dirt.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
