After the material is homogenized in the homogenizing bin, the material is discharged through fluidization and enters an automatic packaging machine, and after high-precision automatic weighing, automatic bagging, automatic sealing, automatic code spraying and high-speed automatic stacking operations, product packaging is completed.
After the polyvinyl chloride powder flows out from the bottom of the homogenization silo, the conditions that the quality of the PVC product is abnormal, and the discharging amount is uneven, the packaging weight deviation is large and the weight is unqualified due to the fact that sundries such as bolts, nuts, plasticizing blocks and the like enter the PVC product possibly because of the abnormal production of the front end, the construction quality of the homogenization silo, the follow-up maintenance failure and the like are caused.
Disclosure of utility model
In order to reduce the probability of abnormal quality of polyvinyl chloride products, rapidly check the occurrence of foreign matters in the products and improve the accuracy of the weight of the packaged products, the utility model provides a polyvinyl chloride resin filter.
The technical scheme adopted for solving the technical problems is as follows: the polyvinyl chloride resin filter comprises a filter cylinder body, an upper connecting pipe, a lower connecting pipe and a screen group; the upper connecting pipe is arranged at the upper part of the filter cylinder body and is used for being connected with a discharge hole of the homogenization silo; the lower connecting pipe is arranged at the bottom of the filter cylinder and is used for being connected with a feeding port of the packaging machine; the screen group is arranged inside the filter cylinder body and used for intercepting sundries in the polyvinyl chloride resin, and comprises a fixed screen which is fixedly installed and a movable screen which is detachably installed, the size of the screen can be adjusted by changing the movable screen according to actual working conditions, and the intercepting effect is improved.
As a further improvement of the utility model, the filter cylinder is formed by surrounding an upper half cylinder body and a lower half cylinder body, and the upper half cylinder body and the lower half cylinder body are connected in a detachable way through a connecting device in an airtight way. It will be readily appreciated that the above-described attachment means may be selected from common attachment means such as flanges, catches, etc. The convenient dismantlement of filter barrel can be realized to this scheme, the inside clearance of barrel of being convenient for.
More preferably, the lower half cylinder has a conical ramp for gathering material towards the lower nozzle, the lower nozzle being arranged at the end of the conical ramp.
More preferably, the fixed screen and the movable screen are respectively disposed on the lower half cylinder horizontal section and the upper half cylinder horizontal section. This scheme is convenient for change or clearance fixed screen cloth and activity screen cloth.
As a further development of the utility model, the upper part of the filter cartridge is further provided with at least one reserved nipple, which comprises a cover plate sealing the nipple inlet. The upper reserved connecting pipe can be connected with other discharge ports of the homogenization storage bin, can be used for cleaning filtered sundries by hand holes, is reserved with a cover plate, and can be rapidly detached according to production conditions to check abnormal conditions.
The beneficial effects of the utility model are as follows: 1) The PVC plastic deformation-preventing device can prevent sundries such as equipment bolts, nuts, plasticizing blocks and the like from entering PVC products, and effectively reduces the probability of abnormal product quality. 2) The utility model is beneficial to rapidly checking the symptom of foreign matters in the product. 3) The utility model ensures that the PVC resin powder is more evenly discharged, and improves the accuracy of the weight of the packaged product.
