Description
Technical Field
The utility model relates to a millipore filtration equipment improves design technical field, especially relates to a switching device for millipore filter bottom.
Background
In industrial production, liquid materials often carry insoluble foreign matters and the like, and in order to remove insoluble substances in a solution and ensure the clarity of the solution, a filter is needed to filter the solution. The filters more commonly used in the industry are filter presses or microporous filters.
The existing microporous filter mainly comprises a filtering cavity and a filter element, wherein after the filter filters for a certain number of times, the filter element is blocked by insoluble substances in a solution, so that the characteristics of high filtering pressure, low filtering speed and the like are caused, the filter needs to be regularly backwashed so as to recover the filtering function of the filter, filter residues backwashed during the backwashing process of the filter are discharged through a bottom cover, the opening and closing of the bottom cover are generally controlled by a pneumatic valve, and the pneumatic valve cannot be opened due to the fact that a material enters the pneumatic valve through an air pipe because the air pipe is directly contacted with the material; and moreover, the pneumatic valve cannot control the opening and closing degree of the bottom cover, the solution in the cavity can flow out greatly and overflows from the recovery basin, and the overflowed solution can not only corrode the ground, but also cause metal waste.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's not enough, provide a switching device for microporous filter bottom, the bottom of this device is opened mode simple structure, has not only practiced thrift the cost, has still improved production efficiency.
In order to achieve the above purpose, the utility model discloses a technical scheme is: the utility model provides an opening and closing device for microporous filter bottom, this opening and closing device is located microporous filter's bottom below, and the bottom is located the cavity bottom, is equipped with the filter core in the cavity, and opening and closing device includes the bottom and is located the stainless steel flange that bottom below set up, the lateral part of bottom install pneumatic control valve, plastic flange connects the plastic flange under the stainless steel flange, plastic flange lower part welding plastic tubing, plastic tubing middle part drilling and installation ball valve.
The stainless steel flange and the plastic flange have the same size.
And a gasket and a sealing ring are arranged between the stainless steel flange and the plastic flange.
And a sealing ring is arranged between the ball valve and the plastic pipe.
The pneumatic control valve is connected with an external air pipe.
The ball valve is made of PPR materials.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model mainly controls the opening degree of the ball valve by hand, further controls the outflow rate of the solution, and prevents the solution from overflowing from the liquid receiving basin and entering a ground pool to cause metal waste; the ball valve replaces a pneumatic control valve, the effect of opening the bottom cover is achieved, the ball valve is not easy to damage, the convenience of opening the bottom cover is greatly improved, the bottom cover opening mode is simple in structure, the cost is saved, and the production efficiency is improved.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic diagram of the present invention before improvement.
The labels in the figures are: 1. a cavity; 2. a filter element; 3. a bottom cover; 4. a flange; 5. a liquid receiving basin; 6. an air tube; 7. a pneumatic control valve; 8. a ball valve; 9. and (3) a plastic pipe.
Detailed Description
The following detailed description is provided to further explain the technical features and advantages of the present invention by referring to the accompanying drawings in combination with the embodiments.
As shown in fig. 1-2, the utility model discloses a switching device for microporous filter bottom, this switching device are located microporous filter's bottom 3 below, and the bottom is located cavity 1 bottom, is equipped with filter core 2 in the cavity, and switching device includes bottom and the stainless steel flange 4 that is located the bottom below setting, the lateral part of bottom install pneumatic control valve 7, plastic flange connects the plastic flange down under the stainless steel flange, plastic flange lower part welding plastic tubing 9, the drilling of plastic tubing middle part and installation ball valve 8.
Furthermore, the stainless steel flange and the plastic flange have the same size. And a gasket and a sealing ring are arranged between the stainless steel flange and the plastic flange. And a sealing ring is arranged between the ball valve and the plastic pipe. The pneumatic control valve is connected with an external air pipe 6. The ball valve is made of PPR material, and PPR is short for polypropylene type III, also called polypropylene random copolymer.
As shown in fig. 2, the improved microporous filter mainly comprises a cavity and a filter element, and the lower part of the improved microporous filter comprises a bottom cover, a flange, a liquid receiving basin 5, an air pipe and a pneumatic control valve, wherein in the operation of the daily backwashing filter, a solution in the cavity flows into the liquid receiving basin through a channel connected with the bottom cover, the bottom cover is controlled to be opened and closed to the pneumatic control valve connected with the air pipe, the air pipe can be seen from the figure to be in contact with the solution in the cavity, after the solution enters the pneumatic control valve through the air pipe, a fine element in the pneumatic control valve is damaged, so that the bottom cover cannot be opened, the filter cannot be normally cleaned due to the fact that the bottom cover cannot be opened, so that the filtration is affected, and the production efficiency is affected to a certain extent. The bottom only needs about 2 seconds from 0 to 100% degree of opening and shutting, can not control the bottom opening and shutting degree, and a large amount of solution can enter into and connect the liquid basin, and because of connect the liquid basin small, liquid flow is big in the twinkling of an eye, and solution can spill over from connecing the liquid basin, and the liquid that overflows can flow into the ground pond to beat the water treatment workshop and lead to the workshop metal extravagant, the liquid that overflows still can will connect ground corrosion around the liquid basin, influence site environment. The existing mode for opening the bottom cover is complex in operation, the production cost is increased due to the fact that a damaged pneumatic control valve needs to be replaced frequently, and the unsmooth opening mode of the bottom cover can reduce labor production efficiency.
The improved structure is shown in figure 1, the bottom cover is opened in a mode that a flange on the filter is made of stainless steel and is provided with a screw hole, a plastic flange with the same size can be made of a plastic plate made of PPR materials, a plastic pipe is welded on one side below the plastic flange, a PPR ball valve is installed on one side of the plastic pipe, after improvement, the bottom cover is opened through a pneumatic control valve and is in a normally open state, and the speed of a solution entering a liquid receiving basin can be controlled only by manually controlling the ball valve in the backwashing process.
