Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a sealed and moisture-proof device for storing finished concrete admixtures. Background Technology

[0002] According to a concrete admixture storage structure disclosed in Chinese Publication No. CN218807966U, belonging to the field of concrete admixture technology, it includes a pressure tank, which is equipped with a negative pressure stabilizing mechanism and a timed stirring mechanism. The timed stirring mechanism includes a connecting plate at the bottom of the pressure tank and a storage pan above the connecting plate. A rotating shaft is rotatably mounted on the connecting plate, and the rotating shaft seals through the storage pan. A stirring plate is mounted on the upper side of the storage pan on the rotating shaft. The lower end of the rotating shaft is connected to a drive motor, which is electrically connected to a controller for controlling the drive motor. The controller has a built-in timed module. This utility model adds a corresponding timed stirring mechanism to the original pressure tank. Through this mechanism, different time settings can be made for different liquid additives to ensure the stability of the admixture composition during use.

[0003] In the storage of concrete admixtures using the aforementioned and existing technologies, although the sealed storage and moisture-proof devices can prevent external moisture from entering to a certain extent, the material inlet and outlet are the areas that come into frequent contact with the external environment. Each time material enters or leaves, outside air inevitably enters the storage device, and the moisture in this air tends to accumulate near the inlet and outlet, thus affecting the quality of the admixture and causing its performance to decline. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where outside air inevitably enters the storage device each time materials are loaded or unloaded, and to propose a sealed and moisture-proof storage device for finished concrete admixtures.

The tank has a discharge port, an electrically controlled valve at the bottom of the discharge port, a transition chamber at the bottom of the electrically controlled valve, a second cover at the bottom of the transition chamber, a tank cover at the top of the tank body, a feed inlet on the top surface of the tank cover, a first cover at the top of the feed inlet, a motor at the top of the tank cover, a stirring shaft at the bottom of the motor, spiral blades on the surface of the stirring shaft, a stirring rod at the bottom of the spiral blades, a partition inside the tank body, and filters on one side of the first exhaust pipe, the second exhaust pipe, the first air inlet pipe, and the second air inlet pipe.

[0006] Preferably, the first exhaust pipe, the second exhaust pipe, the first air inlet pipe, and the second air inlet pipe are all integrally formed with the tank body, and the partition is welded to the tank body. The partition is funnel-shaped. The first exhaust pipe and the first air inlet pipe are located on the top of the partition. The first exhaust pipe and the first air inlet pipe are mirror images of the tank body. The second exhaust pipe is perpendicular to the first exhaust pipe, and the second air inlet pipe is perpendicular to the first air inlet pipe.

[0007] Preferably, the can lid is installed on the top surface of the can body and is connected to the flange of the can body; the motor is installed on the top surface of the can lid and is bolted to the can lid; the first cover is bolted to the feed inlet; the stirring shaft passes through the can lid and the partition plate and is shaft-connected to the motor.

[0008] Preferably, the spiral blades are located at the top of the partition and are welded to the stirring shaft, and the stirring rods are located at the bottom of the partition and are welded to the stirring shaft.

[0012] Beneficial effects

[0013] In this invention, a partition is welded inside the tank to separate the internal space. The top of the partition is a transition chamber, and the bottom is a storage chamber. When materials enter the tank, they first fall into the transition chamber at the top of the partition for temporary storage. During this process, a fan blows outside air into the heater, where heating rods dry the air. The dried air is then transported through a conveying pipe to the first and second air inlets, and then into the transition and storage chambers of the tank. Air exchange occurs between the air in the transition and storage chambers, allowing humid air inside the tank to be discharged through the first and second exhaust pipes, preventing it from entering the storage chamber. The humid air then falls into the storage chamber at the bottom of the partition via spiral blades. Furthermore, a transition chamber is added to the bottom of the electrically controlled valve at the discharge port to prevent humid air from directly entering the tank through the inlet and outlet. This solves the problem of unavoidable outside air entering the storage device each time materials are fed in or out. Attached Figure Description

The tank body 1 has a partition 17 inside. A filter screen 18 is provided on one side of the first exhaust pipe 2, the second exhaust pipe 3, the first air inlet pipe 4, and the second air inlet pipe 5. The first exhaust pipe 2, the second exhaust pipe 3, the first air inlet pipe 4, and the second air inlet pipe 5 are all integrally formed with the tank body 1, and the partition 17 is welded to the tank body 1. The partition 17 is funnel-shaped. The first exhaust pipe 2 and the second exhaust pipe 3 are integrally formed with the tank body 1, and the first exhaust pipe 4 and the second air inlet pipe 5 are all integrally formed with the tank body 1. An air inlet pipe 4 is located on top of the partition 17. The first exhaust pipe 2 and the first air inlet pipe 4 are mirror images of each other with the tank body 1 as the center. The second exhaust pipe 3 is perpendicular to the first exhaust pipe 2, and the second air inlet pipe 5 is perpendicular to the first air inlet pipe 4. The tank cover 10 is installed on the top surface of the tank body 1 and is connected to the flange of the tank body 1. The motor 11 is installed on the top surface of the tank cover 10 and is bolted to the tank cover 10. The first sealing cap 16 is bolted to the feed inlet 15. The stirring shaft 12 passes through the tank cover 10 and the partition 17, and is shaft-connected to the motor 11. Spiral blades 13 are located on top of the partition 17 and are welded to the stirring shaft 12. The stirring rod 14 is...

The filter screens 18 are all set inside the tank body 1 and are threaded to the first exhaust pipe 2, the second exhaust pipe 3, the first air inlet pipe 4 and the second air inlet pipe 5. The air supply pipe 6 is flanged to the first air inlet pipe 4 and the second air inlet pipe 5. The top surface of the heater 7 is flanged to the bottom surface of the air supply pipe 6. The fan 8 is installed on the bottom surface of the heater 7 and is bolted to the heater 7. The electric control valve 20 is installed on the discharge port 19 and is flanged to the discharge port 19. The top surface of the transition chamber 21 is flanged to the bottom surface of the electric control valve 20. The second cover 22 is threaded to the bottom surface of the transition chamber 21.

[0024] Tank 1 is the main container for storing concrete admixtures, providing storage space for them. The first exhaust pipe 2 and the second exhaust pipe 3 are both located on the surface of tank 1, allowing humid air to escape during air exchange. The second exhaust pipe 3 and the first exhaust pipe 2 are located in the transition chamber and storage chamber of tank 1, respectively, maintaining a dry environment inside the tank. The first air inlet pipe 4 and the second air inlet pipe 5 are channels for dry air to enter the tank, also installed in the transition chamber and storage chamber of tank 1, respectively. Filters 18 are installed on the first exhaust pipe 2, the second exhaust pipe 3, the first air inlet pipe 4, and the second air inlet pipe 5 to prevent admixtures from flowing into the air inlet and exhaust pipes. The air supply pipe 6 connects the heater 7 to the first air inlet pipe 4 and the second air inlet pipe 5, responsible for supplying dry air. The heater 7 contains heating rods that heat and dry the outside air blown in by the fan 8, reducing air humidity. The blower 8 blows outside air into the heater 7 and pushes dry air to flow in the air supply pipe 6, thereby entering the tank 1 through the first air inlet pipe 4 and the second air inlet pipe 5. The control console 9, located on one side of the tank 1, can be used to adjust the speed of the blower 8 and the motor 11, control the temperature of the heater 7, and open and close the electrically controlled valve 20. The discharge port 19 is the channel for the admixture to flow out of the tank 1. The electrically controlled valve 20 at its bottom opens and closes according to the control signal from the control console 9, thereby controlling the discharge of the admixture. The transition chamber 21 at the bottom of the electrically controlled valve 20 acts as a buffer, preventing outside humid air from directly entering the tank 1 through the discharge port 19; the second cover 22 is used to seal the bottom of the transition chamber 21 and opens when discharge is needed. The tank cover 10 is connected to the tank 1 via a flange, facilitating installation and disassembly while ensuring the airtightness of the tank 1. The feed inlet 15 is located on the top surface of the tank cover 10 and serves as the channel for the admixture to enter the tank 1. The first cover 16 is used to seal the feed inlet 15 to prevent external moisture, dust, etc. from entering. The motor 11 at the top of the tank cover 10 rotates when energized, driving the stirring shaft 12 to rotate. The spiral blades 13 are mounted on the stirring shaft 12 and rotate at the top of the partition 17, conveying the material entering the transition chamber to the storage chamber of the tank 1. The stirring rod 14 is located at the bottom of the partition 17, stirring the admixture in the storage chamber to prevent clumping and ensure uniformity. The partition 17 divides the internal space of the tank 1 into a transition chamber and a storage chamber, allowing the material to be temporarily stored in the transition chamber and dried by air displacement before entering the storage chamber. Specific Implementation Example 2:

[0026] Reference Figure 1-4A sealed and moisture-proof storage device for finished concrete admixtures, further based on the basic structure in Specific Embodiment 1, allows the following process: When concrete admixtures need to be added to tank 1, the first cover 16 is opened, allowing the material to enter the transition chamber at the top of the partition 17 inside tank 1 through the feed inlet 15. At this time, the control console 9 starts the fan 8 and heater 7. The fan 8 blows outside air into the heater 7, where it is heated and dried by the heating rods inside. The dried air is then transported through the air supply pipe 6 to the first air inlet pipe 4 and the second air inlet pipe 5, thus entering the transition chamber and storage chamber of tank 1 to exchange with the air inside the tank. The humid air is discharged through the first exhaust pipe 2 and the second exhaust pipe 3. During this process, the filter screen 18 prevents the admixture from flowing into the first air inlet pipe 4, the second air inlet pipe 5, the first exhaust pipe 2, and the second exhaust pipe 3. The motor 11 drives the stirring shaft 12 and the spiral blades 13 to rotate, ensuring even distribution of the material in the transition chamber and transporting the admixture into the storage chamber at the bottom of the partition 17. The stirring rod 14 stirs the admixture in the storage chamber to prevent clumping. During discharge, the control console 9 opens the electronically controlled valve 20, allowing the admixture to enter the transition chamber 21. At this time, the second cover 22 closes to prevent the entry of humid air from the outside. When it is time to release the admixture, simply open the second cover 22 to discharge the material.

[0027] In summary:

[0028] 1. In this utility model, a partition 17 is welded inside the tank body 1 to separate the internal space of the tank body 1. The top of the partition 17 is a transition chamber, and the bottom of the partition 17 is a storage chamber. When the material enters the tank body 1, it first falls into the transition chamber at the top of the partition 17 for temporary storage. During this process, the blower 8 blows outside air into the heater 7, where the heating rod inside the heater 7 dries the air. The air is then transported through the air supply pipe 6 to the first air inlet pipe 4 and the second air inlet pipe 5, and then enters the tank body 1 through the first air inlet pipe 4 and the second air inlet pipe 5. In the transition chamber and storage chamber, air exchange with the internal transition chamber and storage chamber of tank 1 is carried out, so that the humid air inside tank 1 is discharged through the first exhaust pipe 2 and the second exhaust pipe 3, preventing the humid air from entering the storage chamber of tank 1. The air then falls into the storage chamber at the bottom of the partition 17 through the spiral blades 13. In addition, a transition chamber is added to the bottom surface of the electric control valve 20 at the discharge port 19 to prevent humid air from directly entering the interior of tank 1 through the feed port 15 and the discharge port 19. This solves the problem that outside air inevitably enters the storage device every time material is fed in or out.
