Description

Technical Field

[0001] The utility model relates to the field of particle material drying, in particular to a particle material drying box. Background Art

[0002] At present, many health care products are packaged and sold in the form of granules, and these granular health care products are basically prepared by mixing powder and liquid through a series of processes, so these granular health care products need to be dried and dehydrated during the preparation process. Patent announcement document CN207066089U discloses an oven that can dry and dehydrate granular materials, but the oven of this structure does not have a mesh plate that can filter gas, so the oven of this structure will inevitably cause dust to adhere to the health care product particles when drying the health care product particles, affecting the purity and storage time of the health care product particles. Utility Model Content

[0003] In view of the above problems, the utility model proposes a drying box for granular materials. The drying box is provided with a dust filter screen plate, which is used to filter the air in the drying box, thereby reducing the dust content of the air in the drying box, ensuring that the surface of the granular materials after drying contains less dust, and improving the purity of the granular materials.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A particle material drying box comprises an outer box body, an inner box body, a grille-type exhaust fan, an electric heating component and a dust filter screen, the inner box body is fixedly arranged in the outer box body by a suspension plate, the inner box body and the suspension plate divide the space in the outer box body into an air intake chamber and an exhaust chamber, the inner box body is provided with an air intake through hole and an exhaust through hole, the exhaust through hole is connected with the exhaust chamber, the air intake through hole and the air intake chamber are in a connected state, the electric heating component is arranged in the air intake chamber or on the inner box body or between the air intake chamber and the inner box body, the dust filter screen is arranged on the box wall of the outer box body, and the mesh holes on the dust filter screen are connected with the air intake chamber, the grille-type exhaust fan is installed in the exhaust chamber, and the grille-type exhaust fan is located at the top of the outer box body.

[0006] The working process of this drying box is as follows: first, the grille exhaust fan works, and the airflow in the environment enters the air intake cavity through the dust filter screen, and then enters the inner box through the air intake hole, and then enters the exhaust cavity through the exhaust hole after entering the inner box, and then is discharged into the environment through the grille exhaust fan. Since the gas entering the inner box is filtered by the dust filter screen, the amount of dust attached to the surface of the granular material after drying can be reduced, and the purity of the granular material (i.e., health products) can be improved.

[0007] In this drying box, the gas is heated by the heating component before or after entering the inner box.

[0008] In this drying box, a grille exhaust fan is used to forcibly form an internal and external convection airflow, which can form a flowing airflow. The flowing airflow has a good drying effect on granular materials. Compared with a simple heating oven, an oven with flowing airflow can dry granular materials at a relatively low temperature, and the low drying temperature can greatly reduce the probability of cracking of granular materials during the drying process.

[0009] Optionally, a drying box is further included, wherein the drying box is arranged on the dust filter screen and is located in the air inlet cavity.

[0010] The specific drying box is a mesh box filled with absorbent (including but not limited to calcium chloride and silica gel, etc.) and cotton balls. After the gas enters, it is first filtered by the dust filter screen and then dehydrated by the drying box to reduce the moisture in the gas, so that the granular material can be dried faster.

[0011] Optionally, a box opening is provided on the inner box body, and the box opening is located on the side wall of the box body. A clamping groove is provided at the box opening of the inner box body, and a box door is inserted into the clamping groove.

[0012] In this type of inner box, the oven door is directly inserted into the clip groove of the inner box. Compared with the rotating door, the clip-type oven door has a simple installation structure and is easy to operate. However, the volume of the entire oven cannot be made too large, so this type of oven is used for small-batch tests in laboratories.

[0013] Optionally, a sealing gasket is provided at the box opening of the inner box body.

[0014] The function of the sealing gasket is to seal the gap between the box opening and the box door to avoid air leakage at the box opening or reduce the amount of air leakage at the box opening.

[0015] Optionally, a handle and an observation glass are provided at the door.

[0016] The handle is provided on the door to facilitate users to carry it, and the observation glass is provided to facilitate users to observe the state of the granular materials during the drying process.

[0017] Optionally, the electric heating component is a coil-type electric heating component, the electric heating component is arranged in the air inlet cavity, and the electric heating component is located on one side of the air inlet hole.

[0018] The coil-type electric heating component heats up quickly and dissipates heat evenly.

[0019] Optionally, there are two exhaust cavities, which are respectively located on both sides of the inner box body, and an exhaust fan is disposed in each exhaust cavity.

[0020] Optionally, a temperature sensor and a gas humidity sensor are provided in the inner box.

[0021] The temperature sensor and the gas humidity sensor are provided to monitor the gas temperature and gas humidity in the inner box.

[0022] Optionally, universal wheels are provided on the outer box body, and the universal wheels are provided at the four corners of the bottom of the outer box body.

[0023] Universal wheels are arranged on the outer box body to facilitate the movement of the entire drying box as needed.

[0024] Optionally, a control host is also included, and the control host is arranged on the box.

[0025] The specific control host is a programmable PLC, the gas humidity sensor and the temperature sensor are electrically connected to the control host, and the electric heating component is also electrically connected to the control host. The gas humidity sensor and the temperature sensor transmit the measured data to the control host, and the control host then adjusts the working state of the electric heating component according to the measured data.

[0026] The beneficial effects of the utility model are as follows: by setting a dust filter screen plate, the air in the oven is filtered by the dust filter screen plate, the dust content of the air in the oven is reduced, the surface of the granular material after drying is ensured to contain less dust, and the purity of the granular material is improved.
