Description

Technical Field

[0001] The utility model relates to the technical field of plasticizer preparation, in particular to a device for preparing a plasticizer for wet-mixed mortar. Background Art

[0002] Wet-mix mortar stabilizer is the core material for producing wet-mix mortar in concrete mixing plants. It is made of a variety of organic and inorganic water-retaining thickening materials and retarders through high-tech. It is a special composite additive that can control the hardening speed and other performance indicators of wet-mix mortar. It has good properties of slow setting, reinforcement, plasticity preservation, improved adhesion, easy for construction workers to apply and spray, and can improve the mechanical properties and durability of wet-mix mortar after hardening. There are usually certain impurities in the preparation process of stabilizer. When used, the presence of impurities can easily cause the quality of the finished wet-mix mortar to decrease, and the raw materials of the stabilizer need to be decontaminated.

[0003] According to the search, the Chinese Patent Network with patent number CN220941782U discloses "a device for preparing plasticizer for wet-mixed mortar". By starting the driving motor and using the connecting rod to drive the cam to rotate, the cross support rod is pushed toward one side of the feed trough, that is, the screen plate is driven to move to one side in the annular groove. After that, under the action of the limiting spring, the cross support rod and the screen plate move in the opposite direction, thereby achieving the effect of left and right vibration. Compared with the method of directly using the screen plate for filtering, the filtration efficiency is improved to a certain extent. However, when the screen plate vibrates left and right, it will move into the annular groove. There are plasticizers that have not been filtered and impurities that have been intercepted on the screen plate. In the process of left and right vibration, these materials are easy to enter the annular groove with the movement of the screen plate, causing blockage and affecting the subsequent operation of the screen plate. At the same time, the amplitude of the left and right vibration is small, and its filtration efficiency still needs to be further improved. Utility Model Content
