Description

Technical Field

[0001] The utility model relates to the technical field of activated alumina production, in particular to a raw material moisture-proof device for activated alumina production. Background Art

[0002] Activated alumina is a porous alumina material that has been specially treated to have a high specific surface area, developed pores, strong adsorption capacity and high catalytic activity. Its chemical formula is generally expressed as Al2O3·nH2O (where 0<n<0.8). It is obtained by high-temperature dehydration of aluminum hydroxide (Al(OH)3). It contains a large number of pore structures inside, which give it unique physical and chemical properties.

[0003] Raw material moisture-proof equipment for activated alumina production generally refers to a device or system specially designed to store and protect the raw materials (mainly aluminum hydroxide or other aluminum-containing compounds) required for activated alumina production from moisture and keep them dry. The function of this type of equipment is to maintain a low humidity environment for the raw materials, prevent the raw materials from absorbing moisture, agglomerating or deteriorating, thereby ensuring that the subsequent processing can proceed smoothly and obtain high-quality activated alumina products.

[0004] During actual use, it was found that although the moisture-proof equipment for raw materials used in the production of activated alumina in the prior art can meet the production needs to a certain extent, the sealing state cannot be quickly restored at the entrance of the equipment after the raw materials are added or sampled, resulting in external humid air easily entering the interior of the equipment, causing the raw materials to be exposed to a humid environment for a long time, thereby increasing the risk of moisture absorption and agglomeration of the raw materials, affecting the quality and activity of the raw materials. Utility Model Content

[0005] The purpose of the utility model is to provide a moisture-proof device for raw materials used in the production of activated alumina, which has the advantages of rapid opening and closing of inlets and outlets and sealing, and solves the problem that external humid air can easily enter the interior of the equipment, causing the raw materials to be exposed to a humid environment for a long time, thereby increasing the risk of moisture absorption and agglomeration of the raw materials, and affecting the quality and activity of the raw materials.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a moisture-proof equipment for raw materials used in the production of activated alumina, comprising a drying mechanism, the drying mechanism comprising a sealing tank, a feed hopper is fixedly installed on the top of the sealing tank, a discharge pipe is fixedly installed on the bottom of the sealing tank, a sealing mechanism is fixedly installed inside the feed hopper and the discharge pipe, the sealing mechanism comprises a sealing tube, a sealing disk is rotatably installed inside the sealing tube, a sealing ring is fixedly installed inside the sealing tube, a cavity is defined inside the sealing ring, an inflation tube is defined inside the sealing tube, the inflation tube is fixedly connected to one side of the cavity, and an air pressure sensor is fixedly installed on the inner wall of the inflation tube.

[0007] As a preferred raw material moisture-proof equipment for the production of activated alumina according to the utility model, two sets of connecting ports are opened on the top of the sealed tank, and connecting pipes are fixedly connected to the tops of the connecting ports. A dehumidification component is fixedly connected to one side of the sealed tank through the connecting ports and the connecting pipes, and the dehumidification component is specifically an internal circulation dehumidifier.

[0008] As a preferred embodiment of the moisture-proof equipment for raw materials used in the production of activated alumina of the utility model, a plurality of legs are fixedly mounted on the bottom of the sealed tank.

[0009] As a preferred raw material moisture-proof device for producing activated alumina of the utility model, one side of the sealing disk is fixedly connected to a rotating shaft, one side of the sealing tube is fixedly installed with a motor, and the motor output shaft is fixedly connected to one side of the rotating shaft through a coupling.

[0010] As a preferred raw material moisture-proof device for producing activated alumina of the utility model, one side of the inflation pipe is fixedly connected to a one-way valve, and one side of the one-way valve is fixedly connected to an air compressor.

[0011] As a preferred embodiment of the moisture-proof equipment for raw materials used in the production of activated alumina of the utility model, a control panel is fixedly mounted on one side of the motor.

[0012] As a preferred embodiment of the moisture-proof equipment for raw materials used in the production of activated alumina of the utility model, the cavity is made of fluororubber.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model controls the opening and closing of the internal channel of the sealing tube by rotating the sealing disk, and inflates the interior of the cavity through the inflation tube, so that one side of the sealing ring is deformed to squeeze the outer wall of the sealing disk to fill the gap between the sealing tube and the sealing disk to complete the sealing. At the same time, the air pressure sensor is used to detect the air pressure inside the inflation tube and the cavity, ensuring that the system operates at the optimal working pressure, improving work efficiency and response speed. When feeding, a specified amount of raw materials is pre-loaded in the feed hopper, and the time and speed of feeding are accurately controlled by the sealing mechanism, while reducing unnecessary opening and closing of the sealing mechanism and accurately controlling the feeding amount. When discharging materials through the discharge pipe, the sealing mechanism can also accurately control the time and speed of feeding, and has the advantages of fast opening and closing of the inlet and outlet and sealing, which solves the problem that external humid air can easily enter the interior of the equipment, causing the raw materials to be exposed to a humid environment for a long time, thereby increasing the risk of moisture absorption and agglomeration of the raw materials, and affecting the quality and activity of the raw materials.

[0020] See also Figure 1-4 , a raw material moisture-proof equipment for producing activated alumina, comprising a drying mechanism 1, the drying mechanism 1 comprising a sealing tank 101, a feed hopper 102 is fixedly installed on the top of the sealing tank 101, a discharge pipe 103 is fixedly installed on the bottom of the sealing tank 101, a sealing mechanism 2 is fixedly installed inside the feed hopper 102 and the discharge pipe 103, the sealing mechanism 2 comprises a sealing tube 201, a sealing disk 202 is rotatably installed inside the sealing tube 201, a sealing ring 203 is fixedly installed inside the sealing tube 201, a cavity 204 is opened inside the sealing ring 203, an air filling tube 205 is opened inside the sealing tube 201, the air filling tube 205 is fixedly connected to one side of the cavity 204, and an air pressure sensor 211 is fixedly installed on the inner wall of the air filling tube 205;

[0021] During use, the opening and closing of the internal channel of the sealing tube 201 is controlled by rotating the sealing disk 202, and the interior of the cavity 204 is inflated through the inflation tube 205, so that one side of the sealing ring 203 is deformed and squeezed to squeeze the outer wall of the sealing disk 202 to fill the gap between the sealing tube 201 and the sealing disk 202 to complete the sealing. At the same time, the air pressure sensor 211 detects the air pressure inside the inflation tube 205 and the cavity 204 to ensure that the system operates at the optimal working pressure, improve work efficiency and response speed, and pre-load a specified amount of raw materials in the feed hopper 102 during feeding. The time and speed of feeding are accurately controlled by the sealing mechanism 2, and the unnecessary opening and closing of the sealing mechanism 2 can be reduced while the feeding amount can be accurately controlled. When discharging through the discharge pipe 103, the sealing mechanism 2 can also accurately control the time and speed of feeding, and has the advantages of fast opening and closing of the entrance and exit and sealing, which solves the problem that external humid air can easily enter the interior of the equipment, causing the raw materials to be exposed to a humid environment for a long time, thereby increasing the risk of moisture absorption and agglomeration of the raw materials, affecting the quality and activity of the raw materials.

[0022] Furthermore, two groups of connection ports 104 are provided on the top of the sealed tank 101, and a connection pipe 105 is fixedly connected to the top of the connection port 104. A dehumidification component 106 is fixedly connected to one side of the sealed tank 101 through the connection port 104 and the connection pipe 105. The dehumidification component 106 is specifically an internal circulation dehumidifier.

[0023] During use, through the cooperation between the connecting port 104, the connecting pipe 105, and the dehumidification component 106, the connecting pipe 105 circulates and dehumidifies the internal environment of the sealed tank 101. Since the internal circulation dehumidifier only processes the air in the enclosed space, it does not need to deal with the uncertain humidity brought by the outdoor fresh air. Therefore, under the same dehumidification effect, compared with the dehumidification system that processes a large amount of fresh air, its energy consumption is lower and the working efficiency is higher.

[0024] Furthermore, a plurality of legs 107 are fixedly mounted on the bottom of the sealed tank 101;

[0025] During use, the sealed can 101 is supported by a plurality of legs 107 to ensure that the sealed can 101 is placed stably.

[0027] During use, the sealing disk 202 can rotate quickly through the cooperation of the rotating shaft 206 and the motor 207, so that the sealing mechanism 2 can quickly control the opening and closing of the internal passage.

[0028] Furthermore, a one-way valve 209 is fixedly connected to one side of the inflation tube 205, and an air compressor 208 is fixedly connected to one side of the one-way valve 209;

[0029] During use, the interior of the inflation tube 205 is inflated by the air compressor 208, and the air pressure inside the cavity 204 and the inflation tube 205 is maintained by the one-way valve 209 to prevent the cavity 204 from losing pressure when the air compressor 208 is powered off or fails, thereby affecting the sealing effect.

[0030] Furthermore, a control panel 210 is fixedly mounted on one side of the motor 207;

[0031] During use, various parameters of the sealing mechanism 2 are displayed and controlled via the control panel 210 .

[0032] Further, the cavity 204 is made of fluororubber;

[0033] During use, the cavity 204 is made of fluororubber to ensure that the elasticity retention and sealing performance of the cavity 204 are still excellent in harsh environments.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
