Abstract
The utility model discloses a device for feeding lime in a painting wastewater treatment process, which comprises a lime hopper and a feeding pump, wherein the feeding pump is connected with the lime hopper through pipelines, and the feeding pump comprises a pump body; both sides of the pump body are respectively provided with a pump cover; a membrane barrier is respectively arranged between each pump cover and the pump body; the upper side and the lower side of each pump cover are respectively provided with an inlet and outlet branch pipe; a longitudinal main valve and a transverse pilot valve are arranged in the pump body; and the inlet and outlet branch pipe, the main valve and the pilot valve are mutually communicated through pipelines arranged inside the pump body. The utility model has the advantages of no shaft gland, no leakage and self absorption function. Because the utility model works in a positive displacement type, and the inlet is a ball valve, the device can not be blocked easily.
Description
Technical field:
The utility model relates to a kind of pump that feeds intake, and specifically is the device that adds lime in a kind of coating wastewater treating processes.
Background technology:
In the coating wastewater treating processes, need add a kind of chemical agent lime, prior art adopts volume pump to add usually, because volume pump accurate measurement, dosage is easy to control, and volume is little, is convenient to characteristics such as installation, uses through actual afterwards, find because lime easily deposits, and have particulate matter to exist, the volume pump suction port is less, and particulate matter is easily blocked at the vacuum breaker place, make the volume pump can't works better, also in pipeline, set up the tap water washpipe afterwards, but it is not obvious to produce effects, to this user also often complaint.
Summary of the invention:
Technical problem to be solved by this invention provides the device that adds lime in a kind of coating wastewater treating processes, and this installs reliable and stable work, can not stopped up by lime.
Add the device of lime in a kind of coating wastewater treating processes described in the utility model, comprise lime bin, with the feed intake pump of lime bin by pipe connection, the pump that it is characterized in that feeding intake comprises the pump housing, both sides at the pump housing are provided with pump cover respectively, barrier film is set respectively between each pump cover and the pump housing is installed into outlet stool respectively in the both sides up and down of pump cover, main valve longitudinally is set in the pump housing, horizontal pilot valve is installed in the pump housing, import and export arm, main valve and pilot valve utilize the passage of pump housing inside to be interconnected respectively.
The utility model device feeds intake to lime, and to adopt pneumatic diaphragm pump, pneumatic diaphragm pump be a kind ofly to be used to carry graininess big to pump, the pump of the slurry flow that impeller pump can't be carried.It is power with pressurized air, promote diaphragm movement, once arrived limit position, the pressurized air distribution valve changes the turnover direction of pressurized gas automatically, thereby changes membranous traffic direction, and it is constantly back and forth moved, this pump does not have the axle envelope, do not have leakage and have the function of self-priming, because positive displacement work and import are ball valve, so be not easy to be blocked.
Description of drawings:
Fig. 1 is the utility model pump structure structure iron that feeds intake.
Embodiment:
The present invention is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, add the device of lime in a kind of coating wastewater treating processes of the present utility model, comprise lime bin, with the feed intake pump of lime bin by pipe connection, the pump that feeds intake comprises the pump housing 1, both sides at the pump housing 1 are provided with pump cover 2 respectively, at each pump cover 2 and 1 of the pump housing barrier film 3 is set respectively, both sides up and down at pump cover 2 are installed into outlet stool 4 respectively, main valve longitudinally is set in the pump housing 1, horizontal pilot valve is installed in the pump housing 1, imports and exports arm 4, main valve and pilot valve utilize the passage 6 of the pump housing 1 inside to be interconnected respectively.On the pump housing, also be provided with sourdine 5.
