Description

Technical Field

[0001] The utility model relates to the technical field of latex product preparation, in particular to a purification device for preparing latex products. Background Art

[0002] Latex is a general term for colloidal emulsions formed by polymer particles dispersed in water. Usually, the water dispersion system of rubber particles is called latex, and the water dispersion system of resin particles is called emulsion. It can be directly used as surface coating, to make films and adhesives, etc., and can be processed into raw rubber and latex products. It is widely used in daily life and can be divided into three categories: natural latex, synthetic latex and artificial latex.

[0003] The existing dialysis device needs to pull up the semipermeable membrane and flush it with water when in use, and the process is relatively cumbersome. Based on these problems, Chinese patent CN219424121U discloses a purification device for preparing a latex product. The purification device for preparing a latex product can support the device by installing support legs, can play an anti-slip role by installing anti-slip pads, can observe the situation inside the tank by installing an observation window, can observe the height of the water injection by installing a connecting vessel, can dialyze and purify the latex by installing a dialysis mechanism, can lift the dialysis assembly by installing a handle, can perform dialysis purification by installing a semipermeable membrane, and can discharge waste water by installing a drain pipe and a valve.

[0004] Before purifying the latex product, the device needs to first introduce the latex product into the semipermeable membrane, then fix the semipermeable membrane to the connecting block, then fix the connecting block to the connecting rod, and finally extend the semipermeable membrane containing the latex product into the tank filled with water. This process not only wastes the time and energy of the staff, but also in the process of pouring the latex product into the semipermeable membrane, the dust in the air will also enter the semipermeable membrane along with the latex product, which not only affects the quality of the latex product after purification, but also brings many inconveniences to the purification of the latex product.
