Problems solved by technology

[0003] Xylene sulfonic acid, usually refers to 2,4-xylene sulfonic acid, is a white crystalline solid; it is mainly used as a catalyst for phenolic and furan resin sand cores or mold curing systems, because the smaller the particle size of the catalyst, the better the catalytic ability Strong, so p-xylene sulfonic acid needs to be ground before use. Most of the existing grinding devices use manual grinding, but the manual grinding method is not effective and efficient, and cannot meet the needs of mass production and processing.

Embodiment Construction

[0016] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0017] see figure 1 with image 3 , a xylene sulfonic acid catalyst grinding device, comprising a base 1, a grinding bucket 10, a grinding plate 11, an extrusion device 14 and a grinding head 21, the left and right sides of the upper surface of the base 1 are fixed with support columns 2 by bolts, The support column 2 is perpendicular to the surface of the base 1 and the upper end of the support column 2 is welded to the connecting plate 3. The center position of the base 1 is fixed with a bearing seat 4 by screws, and a rolling bearing is installed inside the bearing seat 4 for rotation, and the bearing seat 4 A rotating shaft 5 is installed on the rolling bearing with an interference fit, and a gear 6 is installed on the rotating shaft 5 with an interference fit. The upper end of the rotating shaft 5 is fixedly connected with a grinding barrel 1...

Abstract

The invention discloses an xylenesulfonic acid catalyst grinding apparatus. The xylenesulfonic acid catalyst grinding apparatus comprises a base, a grinding drum, a grinding plate, an extruding apparatus and a grinding head, wherein the left side and the right side of the upper surface of the base are respectively fixedly provided with supporting columns by virtue of bolts, a bearing seat is fixedly installed on the center of the base by virtue of a screw, a roller bearing in the bearing seat is provided with a rotating shaft in an interference fit manner, the rotating shaft is provided with agear in an interference fit manner, the upper end of the rotating shaft is fixedly connected with the grinding drum, and the extruding apparatus is fixedly installed on the center of the upper side of a connecting plate. When the xylenesulfonic acid catalyst grinding apparatus moves downwardly, a distance between the lower surface of the grinding head and the upper surface of the grinding plate can be reduced, an effect for increasing an extruding force and matching the rotation of the grinding drum can be achieved, so that the xylenesulfonic acid catalyst can be more sufficiently ground; andmeanwhile, in the up-down movement process of the grinding head, an effect for vibrating the grinding plate can be achieved, and sieve pores in the grinding plate can be effectively prevented from being blocked.

Description

technical field [0001] The invention relates to a grinding device, in particular to a xylenesulfonic acid catalyst grinding device. Background technique [0002] In a chemical reaction, a substance that can change the chemical reaction rate (increase or decrease) of the reactants without changing the chemical balance, and whose quality and chemical properties have not changed before and after the chemical reaction is called a catalyst (a solid catalyst is also called a catalyst). According to statistics, more than 90% of industrial processes use catalysts, such as chemical, petrochemical, biochemical, and environmental protection. There are many kinds of catalysts, which can be divided into liquid catalysts and solid catalysts according to the state; according to the phase state of the reaction system, they can be divided into homogeneous catalysts and heterogeneous catalysts. Homogeneous catalysts include acid, alkali, soluble transition metal compounds and peroxide catalys...
