A detection mechanism is fixedly connected to the upper surface of the storage tank, and a dehumidification mechanism is rotatably connected to the inner wall of the storage tank. The dehumidification mechanism includes a rotating shaft rotatably connected to the inner wall of the storage tank. A cleaning rod and a stirring plate are fixedly connected to the outer surface of the rotating shaft, and a filter screen is fixedly connected to the inner wall of the storage tank. This utility model relates to the field of calcium oxide storage technology. This calcium oxide storage device draws humid air from the tank by activating a centrifugal fan.

Description

Technical Field

[0001] This utility model relates to the field of calcium oxide storage technology, specifically a calcium oxide storage device. Background Technology

[0002] Calcium oxide is an important chemical raw material widely used in steel, construction, and chemical industries. Because calcium oxide is hygroscopic, it gradually deteriorates and loses its quality when exposed to air; therefore, appropriate storage techniques are necessary to maintain its quality.

[0003] The patent publication number "CN219791217U" discloses a "calcium oxide storage device," which includes a storage tank. The storage tank has a dehumidification mechanism inside, an inlet at the top, an outlet at the bottom, and a support rod fixedly mounted above the inside of the tank. A hollow motor housing is located in the center of the support rod. The dehumidification mechanism includes a drive motor, a stirring rod, and blade assemblies. The drive motor is fixedly mounted inside the motor housing, and its output shaft is connected to the stirring rod. Multiple blade assemblies are sleeved on the outside of the stirring rod. Firstly, the sealing cap and adsorbent effectively prevent calcium oxide from being contaminated by external factors. A humidity sensor detects the humidity level inside the storage tank, and moisture is removed by an electric heating wire and the dehumidification mechanism, preventing clumping and demonstrating a higher level of intelligence.

[0004] When the stirring mechanism in the existing calcium oxide storage device stirs the calcium oxide, it inevitably generates a large amount of fine powder. This powder rises with the airflow to the surface of the adsorbent at the top of the storage tank, forming a dense covering layer. The powder blocks the filter pore structure of the adsorbent, hindering its contact with humid air, resulting in a significant decrease in moisture absorption efficiency. Therefore, there is a problem of low moisture absorption efficiency.

[0005] Therefore, this invention provides a calcium oxide storage device to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a calcium oxide storage device that solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a calcium oxide storage device, comprising a storage tank, a detection mechanism fixedly connected to the upper surface of the storage tank, and a dehumidification mechanism rotatably connected to the inner wall of the storage tank. The detection mechanism includes a feed pipe fixedly connected to the upper surface of the storage tank, a cover plate threadedly connected to the inner wall of the feed pipe, and a laser distance sensor fixedly connected to the inner wall of the cover plate. The dehumidification mechanism includes a rotating shaft rotatably connected to the inner wall of the storage tank, a cleaning rod and a stirring plate fixedly connected to the outer surface of the rotating shaft, a filter screen fixedly connected to the inner wall of the storage tank, a sliding frame attached to the upper surface of the filter screen, a silica gel adsorption layer filled in the inner wall of the sliding frame, and a centrifugal fan fixedly connected to the upper surface of the storage tank. The outer surface of the cleaning rod is slidably connected to the lower surface of the filter screen.

[0008] Furthermore, the suction port of the centrifugal suction fan is fixedly connected to a solenoid valve, the other end of the solenoid valve is fixedly connected to a hose, the other end of the hose is fixedly connected to a sealing plate, and the outer surface of the sealing plate is hinged to the outer surface of the storage tank.

[0009] By adopting the above technical solution, the solenoid valve can be used to easily seal the hose, preventing gas from entering the storage tank from the hose.

[0010] Furthermore, a first humidity sensor is fixedly connected to the upper surface of the sealing plate, and multiple sets of temperature sensors and a second humidity sensor are fixedly connected to the inner wall of the storage tank. A control panel is fixedly connected to the outer surface of the storage tank.

[0011] Using the above technical solution, the first humidity sensor facilitates the detection of air humidity above the first heating resistance wire, and multiple temperature sensors and a second humidity sensor facilitate the detection of temperature and humidity of calcium oxide at different heights in the storage tank.

[0012] Furthermore, a geared motor is fixedly connected to the upper surface of the storage tank, the output end of the geared motor is fixedly connected to the upper end of the rotating shaft, and a pressure relief valve is fixedly connected to the upper surface of the storage tank.

[0013] Using the above technical solution, by starting the geared motor, the output shaft of the geared motor drives the rotating shaft to rotate, and the rotating shaft drives multiple sets of stirring plates to rotate. The rotation of the stirring plates facilitates the stirring of calcium oxide in the storage tank and prevents clumping.

[0014] Furthermore, multiple sets of first heating resistance wires are fixedly connected to the inner wall of the stirring plate, and multiple sets of second heating resistance wires are spaced apart inside the storage tank.

[0015] By adopting the above technical solution, the calcium oxide in the storage tank can be heated by activating the first heating resistance wire and the second heating resistance wire. The calcium oxide is heated more evenly by simultaneously heating the inner wall and the middle part of the storage tank.

[0016] Furthermore, a sealing gasket is attached to the lower surface of the laser distance sensor, and a sealing groove is provided on the upper surface of the feed pipe, while a discharge valve is fixedly connected to the lower surface of the storage tank.

[0017] Using the above technical solution, the lower surface of the laser distance sensor is used to compress the sealing gasket, which facilitates the sealing of the feed pipe.

[0018] Beneficial effects

[0019] This invention provides a calcium oxide storage device. Compared with the prior art, it has the following advantages:

[0020] 1. This calcium oxide storage device draws humid air from the tank by activating a centrifugal fan. The air passes through a filter screen to intercept dust and a silica gel adsorption layer to absorb moisture before being discharged. At the same time, the rotating shaft drives the cleaning rod to rotate. The rotation of the cleaning rod rubs against the lower surface of the filter screen, which facilitates the removal of calcium oxide debris adsorbed on the lower surface of the filter screen. This prevents calcium oxide debris from continuously adsorbing on the lower surface of the filter screen, which would reduce the air permeability of the lower surface of the filter screen.

[0021] 2. This calcium oxide storage device can activate a laser distance sensor to detect the calcium oxide level in the storage tank when the reduction motor stops working and the concentration of calcium oxide debris in the storage tank is low, thereby facilitating timely replenishment of calcium oxide.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 4 This application provides a calcium oxide storage device, including a storage tank 1. A detection mechanism 2 is fixedly connected to the upper surface of the storage tank 1, and a dehumidification mechanism 3 is rotatably connected to the inner wall of the storage tank 1. The dehumidification mechanism 3 includes a rotating shaft 306 rotatably connected to the inner wall of the storage tank 1. A cleaning rod 315 and a stirring plate 307 are fixedly connected to the outer surface of the rotating shaft 306. A filter screen 316 is fixedly connected to the inner wall of the storage tank 1. A sliding frame 310 is attached to the upper surface of the filter screen 316. The inner wall of the sliding frame 310 is filled with a silicone adsorption layer 311. A centrifugal fan 312 is fixedly connected to the upper surface of the storage tank 1. The outer surface of the cleaning rod 315 is slidably connected to the lower surface of the filter screen 316.

[0031] Furthermore, a solenoid valve 301 is fixedly connected to the air intake of the centrifugal suction fan 312, a hose 302 is fixedly connected to the other end of the solenoid valve 301, a sealing plate 303 is fixedly connected to the other end of the hose 302, the outer surface of the sealing plate 303 is hinged to the outer surface of the storage tank 1, a first humidity sensor 304 is fixedly connected to the upper surface of the sealing plate 303, and multiple sets of temperature sensors 313 and second humidity sensors 314 are fixedly connected to the inner wall of the storage tank 1, a control panel 4 is fixedly connected to the outer surface of the storage tank 1, a reduction motor 305 is fixedly connected to the upper surface of the storage tank 1, the output end of the reduction motor 305 is fixedly connected to the upper end of the rotating shaft 306, and a pressure relief valve 6 is fixedly connected to the upper surface of the storage tank 1. Multiple sets of first heating resistance wires 308 are fixedly connected to the inner wall of the stirring plate 307, and multiple sets of second heating resistance wires 309 are spaced apart inside the storage tank 1.

[0032] In this embodiment, the centrifugal fan 312 is activated to draw humid air from the tank. After the air passes through the filter screen 316 to intercept dust and the silica gel adsorption layer 311 to adsorb moisture, it is discharged. At the same time, the rotating shaft 306 drives the cleaning rod 315 to rotate. The rotation of the cleaning rod 315 rubs against the lower surface of the filter screen 316, which facilitates the removal of calcium oxide debris adsorbed on the lower surface of the filter screen 316. This prevents the calcium oxide debris from continuously adsorbing on the lower surface of the filter screen 316, which would reduce the air permeability of the lower surface of the filter screen 316.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the detection mechanism 2 includes a feed pipe 203 fixedly connected to the upper surface of the storage tank 1, a cover plate 202 threadedly connected to the inner wall of the feed pipe 203, and a laser distance sensor 201 fixedly connected to the inner wall of the cover plate 202.

[0034] Furthermore, a sealing gasket 204 is attached to the lower surface of the laser distance sensor 201, and a sealing groove is provided on the upper surface of the feed pipe 203. A discharge valve 5 is fixedly connected to the lower surface of the storage tank 1.

[0035] In this embodiment, when the reduction motor 305 stops working and the concentration of calcium oxide debris in the storage tank 1 is low, the laser distance sensor 201 can be activated to detect the calcium oxide level in the storage tank 1, thereby facilitating timely replenishment of calcium oxide.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: First, calcium oxide is added to storage tank 1 through feed pipe 203. The feed pipe 203 is sealed by rotating cover plate 202. The material height is monitored in real time by laser distance sensor 201. Then, reduction motor 305 is started, which drives shaft 306 to rotate stirring plate 307. This prevents calcium oxide from clumping and achieves uniform dehumidification by synchronously heating the first heating resistance wire 308 in stirring plate 307 with the second heating resistance wire 309 on tank wall. At the same time, centrifugal fan 312 is started to draw out humid air from the tank. After dust is intercepted by filter screen 316 and moisture is absorbed by silica gel adsorption layer 311, the air is discharged. Simultaneously, shaft 306 drives cleaning rod 315 to rotate, and the rotating cleaning rod 315 rubs the lower surface of filter screen 316. This facilitates the removal of calcium oxide debris adsorbed on the lower surface of the filter screen 316, preventing the continuous adsorption of calcium oxide debris on the lower surface of the filter screen 316 and thus reducing the air permeability of the lower surface of the filter screen 316. Multiple temperature sensors 313 and a second humidity sensor 314 in the storage tank 1 facilitate the detection of temperature and humidity of calcium oxide at different heights in the storage area. When calcium oxide reacts with water, causing excessive pressure in the storage tank 1, the pressure relief valve 6 can quickly release the gas in the storage tank 1, preventing the storage tank 1 from exploding. It should be noted that when the reduction motor 305 stops working and the concentration of calcium oxide debris in the storage tank 1 is low, the laser distance sensor 201 can be activated to detect the calcium oxide height in the storage tank 1.
