Description

Technical Field

[0001] This utility model relates to the field of ventilation and moisture-proof technology for storage tanks, and in particular to an intelligent ventilation and moisture-proof structure for cement storage tanks. Background Technology

[0002] Cement, also known as cement, is a powdery hydraulic inorganic binder that hardens when mixed with water. It is not usually used alone, but rather combined with sand and gravel to form mortar or concrete. In construction sites, storage tanks are often needed to hold large quantities of cement. Cement storage tanks are closed containers for storing bulk materials and are suitable for storing bulk materials such as grain, cement, and fly ash.

[0003] A search revealed that patent (application number: 202022505658.1) discloses "a novel cement storage tank". This device uses a locking block and a stop block to move a side brush plate to one side of the mounting plate. The side brush plate abuts against the stop block, causing the stop block to move into the first spring groove. The side brush plate then moves the locking block into the mounting groove. Afterward, the side brush plate is pushed downward, causing the side brush plate to move the locking block into the locking groove. At the same time, the stop block pops out and abuts against the top of the side brush plate to install and fix the side brush plate.

[0004] However, existing cement storage tanks directly place cement inside during storage. If left for too long, moisture and humidity from the air will seep into the tank, causing the cement to become damp, clump, and harden, reducing its hardness and making it unusable. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an intelligent ventilation and moisture-proof structure for cement storage tanks, which overcomes the shortcomings of the prior art and effectively solves the problem that when cement is placed directly in the tank, moisture and humidity in the air will penetrate into the tank, causing the cement to clump and harden, thus reducing the hardness of the cement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart ventilation and moisture-proof structure for a cement storage tank includes a storage tank body. A ventilation mechanism is connected to the top of the storage tank body, and a discharge mechanism is connected to the bottom of the storage tank body. The ventilation mechanism includes a top cover, a fixing frame fixed to the top of the top cover, a fixing pipe inserted and fixed between the fixing frame and the top cover, a ventilation pipe slidably connected inside the fixing pipe, a fan connected to the top of the ventilation pipe, a sleeve plate sleeved and fixed to the bottom of the outer wall of the ventilation pipe, a multi-stage push rod motor connected to one end of the top of the sleeve plate, and an air outlet assembly connected to the bottom of the ventilation pipe. The air outlet assembly includes a circular shell, scrapers fixed at equal intervals around the outer wall of the circular shell, air outlets inserted and fixed at equal intervals around the top of the circular shell, a humidity sensor installed on the top of the circular shell, a servo motor installed on the top of the inner wall of the circular shell, and a pressure sensor installed on the bottom of the circular shell.

[0008] When material is added to the storage tank, the multi-stage push rod motor retracts, causing the ventilation duct to move upward, bringing the air outlet assembly closer to the top cover. After the material is added, the multi-stage push rod motor extends, causing the ventilation duct to move downward, so that the bottom of the air outlet assembly comes into contact with the top of the material inside the storage tank. When the pressure sensor receives pressure after contacting the material, the multi-stage push rod motor stops extending, and the servo motor starts, driving two gears to mesh and rotate, causing the circular shell to rotate around the ventilation duct. The scraper smooths the material, and the humidity sensor detects the humidity inside the storage tank. The fan ventilates and dries the storage tank through the ventilation duct, the circular shell, and the air outlet.

[0009] Preferably, a feed inlet is provided on one side of the top of the top cover, and a round cover is inserted into the top of the feed inlet.

[0010] Materials are added into the storage tank through the feed inlet.

[0011] Preferably, a solenoid valve is provided at the connection between the fan and the ventilation duct, and a filter screen is provided at one end of the fan's air inlet.

[0012] When the ventilation and drying of the storage tank is completed, the solenoid valve is closed to prevent the inside of the storage tank from communicating with the outside. The filter screen can reduce the entry of objects such as willow catkins into the storage tank.

[0013] Preferably, the annular inner wall of the fixed pipe is provided with a sliding groove, and the outer wall of the ventilation pipe is fixed with a sliding strip that matches the sliding groove.

[0014] By sliding the slider along the groove, the ventilation duct can be prevented from rotating inside the fixed duct.

[0015] Preferably, the outer wall of the ventilation pipe is rotatably connected to the circular shell through a sealed bearing, and the bottom end of the outer wall of the ventilation pipe and the output shaft of the servo motor are both fitted with meshing gears.

[0016] A servo motor drives two gears to mesh and rotate, causing the round shell to rotate around the ventilation pipe.

[0017] Preferably, the discharge mechanism includes a discharge pipe and a spiral conveying roller rotatably connected inside the discharge pipe, and the top end of the discharge pipe is inserted and connected to the bottom of the storage tank body.

[0018] By rotating the screw conveyor roller, the material is conveyed in the discharge pipe and discharged from the bottom of the discharge pipe, which avoids the problem of not being able to stop the closing when picking up material.

[0019] Preferably, one end of the spiral conveying roller is connected to a rotary handle located outside the discharge pipe, and a pipe plug is inserted into the bottom end of the discharge pipe. A control box for installing the controller is provided outside the storage tank body, and the humidity sensor, servo motor, fan and pressure sensor are all electrically connected to the controller.

[0020] The screw conveyor roller is rotated by the rotary handle, and the bottom of the discharge pipe is closed by the pipe plug to prevent moisture from coming into contact with the material inside the storage tank from the bottom.

[0021] The beneficial effects of this utility model are as follows:

[0022] A multi-stage push rod motor extends, driving the ventilation duct downwards so that the bottom of the air outlet assembly comes into contact with the top of the material inside the storage tank. When the pressure sensor receives pressure after contacting the material, the multi-stage push rod motor stops extending, and a servo motor starts, driving two gears to mesh and rotate, causing the circular shell to rotate around the ventilation duct. A scraper smooths the material, and a humidity sensor detects the humidity inside the storage tank. The fan ventilates and dries the storage tank through the ventilation duct, the circular shell, and the air outlet. This effectively solves the problem in existing technologies where cement is placed directly inside the tank, allowing moisture and dampness from the air to penetrate the tank, causing the cement to clump and harden, thus reducing its hardness.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example:

[0030] Reference Figure 1-4 A smart ventilation and moisture-proof structure for a cement storage tank includes a storage tank body 1, a ventilation mechanism 2 connected to the top of the storage tank body 1, and a discharge mechanism 3 connected to the bottom of the storage tank body 1. The ventilation mechanism 2 includes a top cover 4, a fixing frame 5 fixed to the top of the top cover 4, a fixing pipe 6 inserted and fixed between the fixing frame 5 and the top cover 4, a ventilation pipe 7 slidably connected inside the fixing pipe 6, a fan 8 connected to the top of the ventilation pipe 7, a sleeve plate 10 sleeved and fixed to the bottom of the outer wall of the ventilation pipe 7, a multi-stage push rod motor 11 connected to the top of the sleeve plate 10, and an air outlet assembly 12 connected to the bottom of the ventilation pipe 7. The air outlet assembly 12 includes a circular shell 13, scrapers 14 fixed at equal intervals around the outer wall of the circular shell 13, air outlets 15 inserted and fixed at equal intervals around the top of the circular shell 13, a humidity sensor 16 installed on the top of the circular shell 13, a servo motor 17 installed on the top of the inner wall of the circular shell 13, and a pressure sensor 18 installed on the bottom of the circular shell 13.

[0031] A feed inlet is provided on one side of the top of the top cover 4. A round cover is inserted into the top of the feed inlet. Material is added into the storage tank body 1 through the feed inlet. A solenoid valve is provided at the connection between the blower 8 and the ventilation pipe 7. A filter screen 9 is provided at one end of the air inlet of the blower 8. When the ventilation and drying of the storage tank body 1 is completed, the solenoid valve is closed to prevent the interior of the storage tank body 1 from communicating with the outside. The filter screen 9 can reduce the entry of objects such as willow catkins into the storage tank body 1. A sliding groove is provided on the annular inner wall of the fixed pipe 6. A sliding strip that matches the sliding groove is fixed on the outer wall of the ventilation pipe 7. The sliding strip slides along the sliding groove to prevent the ventilation pipe 7 from rotating inside the fixed pipe 6.

[0032] The outer wall of the ventilation pipe 7 is rotatably connected to the circular shell 13 via a sealed bearing. Gears meshing with each other are fixedly fitted onto the bottom end of the outer wall of the ventilation pipe 7 and the output shaft of the servo motor 17. The servo motor 17 drives the two gears to mesh and rotate, causing the circular shell 13 to rotate around the ventilation pipe 7. The discharge mechanism 3 includes a discharge pipe 19 and a spiral conveying roller 20 rotatably connected within the discharge pipe 19. The top end of the discharge pipe 19 is inserted and connected to the bottom of the storage tank body 1. By rotating the spiral conveying roller 20, the material is conveyed within the discharge pipe 19 and discharged from the bottom of the discharge pipe 19. The material is discharged from the bottom, which avoids the problem of not being able to stop the closing when picking up the material. One end of the screw conveyor roller 20 is connected to a rotating handle 21 located outside the discharge pipe 19. A pipe plug 22 is inserted into the bottom end of the discharge pipe 19. A control box for installing the controller is set outside the storage tank body 1. The humidity sensor 16, servo motor 17, fan 8 and pressure sensor 18 are all electrically connected to the controller. The rotating handle 21 rotates the screw conveyor roller 20, and the bottom end of the discharge pipe 19 is closed through the pipe plug 22 to prevent moisture from contacting the material in the storage tank body 1 from the bottom.

[0033] Working principle:

[0034] During operation, when material is added to the storage tank body 1, the multi-stage push rod motor 11 retracts, causing the ventilation pipe 7 to move upward, bringing the air outlet assembly 12 closer to the top cover 4. After the material is added, the multi-stage push rod motor 11 extends, causing the ventilation pipe 7 to move downward, so that the bottom of the air outlet assembly 12 abuts against the top of the material in the storage tank body 1. When the pressure sensor 18 contacts the material and receives pressure, the multi-stage push rod motor 11 stops extending, and the servo motor 17 starts, driving two gears to mesh and rotate, causing the circular shell 13 to rotate around the ventilation pipe 7. The scraper 14 smooths the material, and the humidity sensor 16 detects the humidity inside the storage tank body 1. The fan ventilates and dries the inside of the storage tank body 1 through the ventilation pipe 7, the circular shell 13, and the air outlet 15.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
