The utility model relates to drying equipment. The drying equipment comprises a drying groove, a first air conveying assembly, a filtering assembly and an air outlet assembly. The drying groove is provided with an air inlet and an air outlet. The first gas conveying assembly comprises a gas conveying main path and a gas conveying branch path, the first end of the gas conveying branch path communicates with the first end of the gas conveying main path, the second end of the gas conveying branch path communicates with the drying groove through the gas inlet, and the second end of the gas conveying main path communicates with the external environment. The filtering assembly comprises a first filter and a second filter, and the first filter and the second filter are both arranged on the gas conveying main path. The air outlet assembly comprises an air outlet main path and an air outlet branch path, the first end of the air outlet main path communicates with the air conveying main path, the communicating position is located on the downstream of the first filter and the second filter, the second end of the air outlet main path communicates with the first end of the air outlet branch path, and the second end of the air outlet branch path communicates with the drying groove through an air outlet. According to the technical scheme, the problem that in the prior art, the clean fresh air conveying rate is low, and consequently the drying efficiency is low is effectively solved.

The utility model relates to a coal tar purification device. Purification structure two includes purification box no. 2, the left side of purification box no. 2 is installed with a plurality of side filter membranes, the left side of purification box no. 2 is installed with the slag removal plate for carrying out the cleaning to the impurity, the bottom of purification box no. 2 is installed with the connecting thin plate for guiding the impurity, the inside of purification box no. 2 is installed with two power assemblies for cooperating with the connecting thin plate and accelerating the impurity right movement. The utility model discloses through the slag removal plate to the impurity cleaning on the side filter membrane, makes the impurity fall to the slag removal pipe in through the connecting thin plate, and through the setting of two power assemblies, accelerates the rate of the impurity to the slag removal pipe conveying, the utility model discloses through the setting of the collection cylinder and the slag removal pipe, makes the baffle close after the slag removal pipe, can take down the collection cylinder and remove the impurity in the collection cylinder, and then is installed below the slag removal pipe, makes purification structure two during the operation can clean the impurity, avoids the shutdown cleaning impurity and influences the impurity cleaning efficiency.

The present application relates to the technical field of metal cutting tools, and provides a micro-textured tool and a processing method thereof, which comprises a tool base body, a fan fin structure micro-texture, a raceway roller structure and a stepped structure are arranged on the tool base body rear face, a plurality of fan fin structure micro-textures are arranged close to the main cutting edge and the edge array of the tool base body, a plurality of stepped structures are equidistantly arranged on one side of the fan fin structure micro-texture, and two groups of raceway roller structures are communicated with the stepped structures and are arranged on the two sides of the stepped structures respectively. The fan fin structure micro-texture, the raceway roller structure and the stepped structure are matched with each other, which can not only promote the occurrence of derivative cutting and the quality of the processed surface, but also reduce the tool wear and prolong the service life of the tool.

The present application relates to a kind of chemical reaction preparation equipment, specifically a kind of reversible esterification reaction control device that catalytic reaction moves to product direction, including truss and electric control heating furnace installed on truss, truss is also installed with cooling mechanism, cooling mechanism is communicated with the inside of reaction dish;Reaction dish is also provided with feeding mechanism and acceleration mechanism, and acceleration mechanism cooperates with feeding mechanism and cooling mechanism.By the way of mechanical interlocking cooperation, the corresponding cooperation relationship between the gas circulation rate in reaction dish, cooling rate, stirring speed and the feeding rate of reactant is established, the faster the stirring speed, the feeding rate of reactant is followed up, at the same time, the gas circulation rate in reaction dish and the cooling rate of gas are also accelerated, to ensure that the concentration of reactant in reaction dish is constantly increasing, and product water is constantly reduced, which is conducive to the direction of product to promote reversible reaction.
