Liquid product high-pressure filtering device and use method thereof

Abstract

The invention discloses a liquid product high-pressure filtering device. The device comprises a pump, a first switching valve, a second switching valve, a third switching valve, a fourth switching valve, a fifth switching valve, a sixth switching valve, a seventh switching valve, an eighth switching valve, a ninth switching valve, a first filter, a second filter and a third filter. Meanwhile, theinvention discloses a use method of the device. Accordingly, by means of mutual cooperation of the multiple switch valves, automatic block removing of the filter screen is achieved, manpower resourcesfor replacing the filter screen for a traditional device are saved, and the service life of the filter screen is prolonged; meanwhile, in the block removing process, downtime is not needed, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a high-pressure filter device for liquid products and a method for using the same, and belongs to the technical field of high-pressure filter for liquid products. Background technique [0002] Traditional liquid products (such as glue, toothpaste, adhesives, etc.) high-pressure filtration devices such as figure 1 As shown, the liquid product enters the filter from the inlet, and the cross-section of the filter is larger than that of the inlet, so the flow rate of the product inside the filter is relatively slow, which is convenient for filtering out impurities. The filter screen is the core component of the filter. It is characterized by a large mesh density and small mesh holes, which can filter out tiny impurities to improve the purity of the product. The filter screen resists the high pressure of the liquid product from the inlet through the compression force of the bolt connection, and at the same time blocks the passage o...

Problems solved by technology

[0003] When the impurities on the filter screen accumulate to a certain extent, it will be blocked and affect the normal flow. At this time, a new filter screen needs to be replaced. The general steps for replacement are: first suspend the flow of liquid products; because the pressure required for the flow of liquid products is very high, so The volume and wall thickness of the filter are very large. To replace the filter, you must first disassemble the filter manually, then remove the fastening bolts for connection, take out the filter, replace it with a new filter, and then re-tighten it. Bolt connection, after a set of procedures, consumes a lot of manpower and time
