Description

Technical Field

[0001] The present application relates to the technical field of calcium carbonate storage, and in particular to a heavy calcium carbonate storage device. Background Art

[0002] Heavy calcium carbonate, also known as heavy calcium carbonate, is made by grinding natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdered inorganic filler with the advantages of high chemical purity, high inertness, resistance to chemical reactions, and thermal stability. During the transfer of heavy calcium carbonate to storage containers, a large amount of dust will occur. The dust in the air will not only pollute the production environment, but also have an impact on the health of the workers. In addition, during the storage process, heavy calcium carbonate powder is prone to precipitation or agglomeration. If it is not handled in a timely manner, the heavy calcium carbonate will easily become blocked at the discharge port when the storage container is discharged, which is not conducive to the next step of production. Utility Model Content

[0003] In order to address the deficiencies of the above-mentioned prior art, the present application provides a heavy calcium carbonate storage device, which can not only avoid the phenomenon of large amounts of dust being emitted during the discharge of heavy calcium carbonate powder, but also avoid the difficulty in discharging due to precipitation or agglomeration of heavy calcium carbonate powder during storage.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A heavy calcium carbonate storage device includes a tank body with a cylindrical structure, an upper end surface of the tank body is provided with a feed port, a stirring rod is provided in the tank body, a stirring blade is provided on the stirring rod, and a discharge port is provided at the bottom of the tank body;

[0006] A dust cover is provided on the side cover around the feed port, one end of the dust cover is open, and two guide rails are provided on both sides of the bottom of the dust cover along its own length direction. The guide rails are installed on the upper end surface of the tank body and extend from the opening to a predetermined length. A fixed seat is provided on the guide rail, and the outer wall of the fixed seat matches the inner wall of the dust cover. Two slide grooves are provided at the bottom of the fixed seat, and the slide grooves match the guide rails one by one.

[0007] The interior of the fixing seat is hollow and is used to place the barrel body in an inverted manner. The inner wall of one side of the fixing seat in the length direction is a V-shaped clamping surface, and the other side is open. A rotating rod is provided at the opening. One end of the rotating rod is rotatably mounted on the top of the fixing seat, and a torsion spring is provided at the rotating mounting position. The rotating rod is used to limit the barrel body inverted in the fixing seat when it is rotated and flipped down.

[0008] The bottom surface of the fixing seat is provided with a baffle groove along its width direction, and the baffle groove runs through the rear end surface of the fixing seat. A baffle is movably placed on the baffle groove to support the inverted barrel body and close or open the barrel body opening;

[0009] A drop opening is provided below the baffle groove, the diameter of the drop opening is smaller than the diameter of the feed opening, the diameter of the barrel flange is larger than the diameter of the feed opening, and when the fixing seat completely enters the dust cover, the drop opening is coaxial with the feed opening.

[0010] The beneficial effect of the present invention is that the barrel body is fixed by a fixed seat, and then the fixed seat is moved to the inside of the dust cover by using the cooperation of the slide groove and the guide rail, so that the barrel body, the discharge port and the feed port remain coaxial, and the baffle can be removed to discharge the heavy calcium carbonate powder in the barrel body. In this process, the dust cover and the fixed seat provide a relatively closed environment for the discharge of heavy calcium carbonate powder, reducing the pollution of the production environment and the harm to the health of the workers caused by the dust emitted during the discharge process. In addition, during the storage of the heavy calcium carbonate powder, the heavy calcium carbonate powder in the tank body is regularly stirred by a stirring rod, which not only evenly distributes the heavy calcium carbonate powder in the tank body after discharge, but also effectively avoids the problem of discharge difficulties caused by the precipitation or agglomeration of the heavy calcium carbonate powder during use, thereby speeding up the discharge speed to a certain extent.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] An embodiment of the present application provides a heavy calcium carbonate storage device, including a tank body 1, a fixing seat 4, a baffle groove 44 and a discharge port 41.

[0020] The tank body 1 is a cylindrical structure, with a feed port 2 provided on the upper end surface of the tank body 1 , a stirring rod 11 provided inside the tank body 1 , a stirring blade provided on the stirring rod 11 , and a discharge port 5 provided at the bottom of the tank body 1 .

[0021] A dust cover 3 is provided on the side cover around the feed port 2, one end of the dust cover 3 is open, and two guide rails 31 are provided on both sides of the bottom of the dust cover 3 along its own length. The guide rails 31 are installed on the upper end surface of the tank body 1 and extend from the opening to a predetermined length. A fixed seat 4 is movable on the guide rail 31, and the outer wall of the fixed seat 4 matches the inner wall of the dust cover 3. Two slide grooves 43 are provided at the bottom of the fixed seat 4, and the slide grooves 43 match the guide rails 31 one by one. The open setting of the dust cover 3 is used to allow the fixed seat 4 to pass through and enter to form a closed unloading environment.

[0022] The interior of the fixing seat 4 is hollow and is used to place the barrel body inverted. The inner wall on one side of the length direction of the fixing seat 4 is a V-shaped clamping surface 46, and the other side is open. A rotating rod 42 is provided at the opening. One end of the rotating rod 42 is rotatably installed on the top of the fixing seat 4, and a torsion spring is provided at the rotating installation. The rotating rod 42 is used to limit the barrel body inverted in the fixing seat 4 when it is rotated and flipped down.

[0023] The bottom surface of the fixed seat 4 is provided with a baffle groove 44 along its own width direction, and the baffle groove 44 runs through the rear end surface of the fixed seat 4. A baffle 45 is movably placed on the baffle groove 44. The baffle 45 is used to support the inverted barrel body and close the barrel body opening. The setting of the baffle groove 44 enables the baffle 45 to move in or out from the side along the width direction, and to move in or out from the rear end of the fixed seat 4 along the length direction.

[0024] The drop port 41 is arranged below the baffle groove 44. The diameter of the inner wall of the barrel body is smaller than the diameter of the drop port 41. The diameter of the drop port 41 is smaller than the diameter of the feed port 2, so that the heavy calcium carbonate powder from the inside of the barrel body can smoothly pass through the drop port 41 and the feed port 2 in sequence. The diameter of the feed port 2 is smaller than the diameter of the barrel body flange to prevent the barrel body from falling into the tank body 1, and when the fixed seat 4 is completely entered into the dust cover 3, the drop port 41 is coaxial with the feed port 2. A stirring rod 11 is provided in the tank body 1, and a stirring blade is provided on the stirring rod 11. A discharge port 5 is provided at the bottom of the tank body 1.

[0025] When in use, the baffle 45 is placed on the top of the barrel body, and then through the setting of the baffle groove 44, the baffle 45 and the barrel body are inverted and placed into the fixing seat 4 along the width direction of the fixing seat 4, and the rotating rod 42 is rotated to fix the barrel body together with the V-shaped clamping surface, while keeping the barrel body and the blanking port 41 coaxial.

[0026] The fixed seat 4 is moved to move the barrel into the dust cover 3. When the fixed seat 4 is completely inside the dust cover 3, the discharge port 41 is coaxial with the feed port 2, that is, the barrel and the feed port 2 remain coaxial. At this time, the baffle 45 is pulled out backward to connect the interior of the barrel with the feed port 2. The heavy calcium carbonate powder inside the barrel enters the interior of the tank 1 through the feed port 2 under the action of gravity. At this point, one feeding is completed. The dust cover 3 and the fixed seat 4 prevent the dust raised during the feeding process from directly contacting the staff and entering the air to pollute the production environment. After the feeding is completed, wait for a period of time until the dust settles, and then remove the fixed seat 4. During the storage of heavy calcium carbonate, in order to avoid the difficulty of discharging the heavy calcium carbonate powder due to precipitation or agglomeration, the inside of the tank body 1 can be stirred regularly using the stirring rod 11. Under the stirring action of the stirring rod 11, the heavy calcium carbonate powder is evenly distributed in the tank body 1, and the discharge of the heavy calcium carbonate powder is smoother when it is taken out.

[0027] The rotating rod 42 includes two horizontal sections and a vertical section vertically arranged between the two horizontal sections. One of the horizontal sections is used to be rotatably connected to the top of the fixed seat 4, and the other horizontal section is used to form a clamping fixation with the V-shaped clamping surface 46 to the inverted barrel body. The vertical section is used to connect the two horizontal sections. When the torsion spring is in a natural state, the vertical section is in a horizontal state. When the rotating rod 42 is in a clamping state, the vertical section is in a vertical state, and the outer side surface of the vertical section facing the opening is flush with the outer wall of the fixed seat 4.

[0028] The top of the dust cover 3 is rotatably provided with a vertically arranged screw 33, and a push rod 32 is movable on the screw 33. The inner side surface of the push rod 32 is flush with the side of the fixed seat 4 with an opening. The push rod 32 is used to push the rotating rod 42 so that the outer side surface of the vertical section does not protrude from the outer wall of the fixed seat 4. When the push rod 32 moves to the preset highest point, the bottom of the push rod 32 is higher than the rotating rod 42. When the push rod 32 moves to the preset lowest point, the outer side surface of the push rod 32 is used to abut against the outer side surface of the vertical section. When the cam 32 is in contact with the outer wall of the dust cover 3, the cam 32 is in contact with the outer wall of the dust cover 3, and the cam 32 is in contact with the inner wall of the dust cover 3. When the cam 32 is in contact with the outer wall of the dust cover 3, the cam 32 is in contact with the outer wall of the dust cover 3, and the cam 32 is in contact with the outer wall of the dust cover 3. When the cam 32 is in contact with the outer wall of the dust cover 3, the cam 32 is not in contact with the outer wall of the dust cover 3, and the cam 32 is not in contact with the outer wall of the dust cover 3. When the cam 32 is in contact with the outer wall of the dust cover 3, the cam 32 is not in contact with the outer wall of the dust cover 3, and the cam 32 is not in contact with the outer wall of the dust cover 3.

[0029] A protrusion 441 extends from the inner wall of the baffle groove 44 along the length direction of the fixing seat 4. There is a predetermined distance between the protrusion 441 and the top and bottom of the baffle groove 44. A groove 451 is opened along the length direction on the side of the baffle 45 facing the fixing seat 4. The groove 451 is used to match the protrusion 441 so that the relative sliding between the baffle 45 and the baffle groove 44 can be carried out more stably.

[0030] Two stirring rods 11 are symmetrically provided on both sides of the guide rail 31 inside the tank body 1. The stirring blades of the two stirring rods 11 are staggered, which enhances the stirring effect and makes the discharge smoother. The two stirring rods 11 pass through the top of the tank body 1 and are coaxially connected to a driving wheel and a driven wheel respectively. The driving wheel and the driven wheel are connected by a transmission belt, and the rotation of the driving wheel is driven by a motor.

[0031] A handle is provided on the baffle 45 to facilitate moving the baffle 45 .

[0032] In application, the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
