Description

Technical Field

[0001] The utility model relates to the technical field of curing agent production, in particular to a curing agent production raw material screening device. Background Art

[0002] Curing agent, also known as hardener, curing agent or setting agent, needs to be added when making adhesives, coatings and castables. The raw materials used for curing agent production are mostly granules or powders, which are prone to agglomeration after long-term storage. Therefore, when making curing agent, it is necessary to screen the agglomerates in the raw materials. The conventional screening method is to directly screen out the agglomerates without reusing the agglomerates, which results in a waste of curing agent raw materials.

[0003] Therefore, a technical solution is currently needed to solve the technical problem of directly screening out lumps in the curing agent raw materials and causing waste during the production of the curing agent. Utility Model Content

[0004] The invention purpose of the utility model is to provide a raw material screening device for curing agent production in order to solve the technical problem that agglomerates in curing agent raw materials are directly screened out during curing agent production, resulting in waste.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A curing agent production raw material screening device, comprising a tank body and a barrel,

[0007] The top of the tank body is provided with a first feed hopper, the bottom of the tank body is provided with a first discharge port, the side of the tank body is provided with a material distribution port, a screen is obliquely provided inside the tank body, and the material distribution port is provided on the side of the lower end of the screen;

[0008] A second feed hopper is provided at the top of the barrel, a second discharge port is provided at the bottom of the barrel, the second feed hopper is arranged below the material distribution port, a rotating shaft is provided in the barrel, a motor is driven to rotate the rotating shaft at the top of the barrel, and a plurality of cutters are connected to the side of the rotating shaft.

[0009] The utility model discloses a raw material screening device for curing agent production. When in use, the curing agent raw material with agglomerates is fed into the tank body from the first feed hopper of the tank body. Under the screening effect of the screen, qualified particles fall below the screen and are further discharged from the first discharge port, while the agglomerated curing agent raw material rolls along the inclined partition to the distribution port and further falls into the barrel from the second feed hopper. The agglomerated curing agent raw material is broken up by a rotating cutter in the barrel and finally discharged through the second discharge port. The present application firstly screens the curing agent material through the screen in the tank body, and then breaks up the screened agglomerated materials by the cutter in the barrel, which not only facilitates the use of qualified raw materials, but also enables the agglomerated raw materials to be recycled, thereby improving the curing agent production quality and reducing the curing agent production cost.

[0010] As a preferred solution of the utility model, a vibration motor is provided in the tank body, and the vibration motor abuts against the bottom of the screen. The vibration motor can drive the screen to vibrate, so that the normal particles of the curing agent raw material on the screen are more likely to fall below the screen, and also make the agglomerated curing agent raw material more likely to roll down to the material distribution port to avoid clogging of the screen.

[0011] As a preferred embodiment of the utility model, a plurality of convex teeth are evenly arranged on the upper surface of the cutter, and the convex teeth are arranged vertically. The agglomerated curing agent raw materials fall from top to bottom in the barrel, and when they fall on the upper surface of the cutter, they collide with the vertically arranged convex teeth, thereby breaking up the agglomerated curing agent. The convex teeth apply vertical force to the agglomerated curing agent, and the cutter rotates horizontally to the agglomerated curing agent. The crushing in two directions enables the agglomerated curing agent to be crushed more thoroughly, which is convenient for the agglomerated curing agent to be used in curing agent production.

[0012] As a preferred solution of the utility model, a drying mechanism is also included, the drying mechanism includes an air supply pipe, the air supply pipe is connected to a fan, the side wall of the barrel is provided with a plurality of air inlet holes, the air inlet holes are connected to the air supply pipe through a branch pipe. By arranging the drying mechanism to supply air into the barrel, the moisture in the curing agent raw material after scattering can be reduced, the time for the curing agent to undergo secondary agglomeration can be extended, and the raw material can be used for the production of the curing agent.

[0013] As a preferred solution of the utility model, the air supply pipe is also connected to an electric heater, which is arranged between the fan and the barrel. The electric heater can heat the air sent into the barrel, and the hot air can be used to dry the curing agent raw materials scattered in the connection, thereby improving the drying efficiency of the curing agent raw materials.

[0014] As a preferred solution of the utility model, an exhaust nozzle is provided on the top of the barrel, which is convenient for accelerating the discharge of water vapor in the barrel and improving the drying efficiency of the curing agent raw material in the barrel.

[0015] As a preferred solution of the utility model, a partition net is arranged on the top of the exhaust nozzle, which can prevent foreign matter from entering the barrel and reduce the curing agent raw materials inside the barrel from scattering out through the exhaust nozzle, thereby protecting the working environment and reducing the waste of curing agent raw materials.

[0016] As a preferred solution of the utility model, a sleeve is detachably provided on the top of the exhaust nozzle, and the partition net is arranged in the sleeve. The partition net is arranged along the cross section of the sleeve, and the sleeve is detachably connected to the exhaust nozzle. The sleeve and the partition net play a role in dust prevention and exhaust for the exhaust nozzle. After long-term use, the sleeve can be removed from the exhaust nozzle to facilitate cleaning of debris or dirt on the partition net, so as to maintain good exhaust performance of the exhaust nozzle.

[0017] As a preferred solution of the utility model, the sleeve is threadedly connected to the exhaust nozzle, so that the connection between the sleeve and the exhaust nozzle is more stable, and the sleeve can be easily assembled and disassembled on the exhaust nozzle.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] The present application firstly screens the curing agent materials through the screen in the tank body, and then breaks up the agglomerated materials through the cutter in the barrel, which not only facilitates the use of qualified raw materials, but also can recycle the agglomerated raw materials, thereby improving the production quality of the curing agent and reducing the production cost of the curing agent.
