Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate processing technology, and in particular to a pulverizer for producing nano-calcium carbonate. Background Technology

[0002] Nano calcium carbonate is widely used in the rubber, plastics, ink, coating, sealant and adhesive industries. Nano calcium carbonate needs to be crushed during processing. Traditional crushing equipment cannot screen the crushed nano calcium carbonate, so subsequent screening is required.

[0003] Existing technology CN209985506U discloses a pulverizer for producing nano-calcium carbonate, including a frame, support legs, a left feeding hopper, a right feeding hopper, a first motor, a first pulverizing shaft, a first pulverizing blade, a second motor, a second pulverizing shaft, a second pulverizing blade, a third motor, a third pulverizing shaft, a third pulverizing blade, a left motor support plate, a right motor support plate, an upper circular roller mill, a lower circular roller mill, a vibrating screen plate, a discharge gate, and a latch. The aforementioned device has the vibrating screen plate located below the lower circular roller mill, which can screen the pulverized nano-calcium carbonate and remove unqualified raw materials.

[0004] However, the sieved nano-calcium carbonate needs to be manually reintroduced into the device, which makes the operation cumbersome and reduces processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a pulverizer for the production of nano-calcium carbonate, which solves the problem that in the existing pulverizer for the production of nano-calcium carbonate, the sieved nano-calcium carbonate needs to be manually put back into the device, resulting in cumbersome operation and reduced processing efficiency.

[0006] To achieve the above objectives, this utility model provides a pulverizer for producing nano-calcium carbonate, comprising a shell and a feed pipe. The feed pipe is fixedly installed on one side of the shell and communicates with the shell. It also includes a screening assembly. The screening assembly includes a rotating plate, a screen plate, a baffle plate, a feed housing, and a pulverizing component. The rotating plate is rotatably connected to the shell and located inside the shell. The screen plate is fixedly connected to the rotating plate and located on one side of the rotating plate. The baffle plate is connected to the screen plate and disposed on the screen plate. The feed housing is fixedly connected to the shell and located inside the shell. The pulverizing component is disposed on the feed housing.

[0007] The screening component further includes a collection frame, which is connected to the outer shell and located inside the outer shell.

[0008] The screening assembly further includes a stirring component, which includes a rotating shaft and stirring blades. The rotating shaft is rotatably connected to the outer shell and is located inside the outer shell. The stirring blades are fixedly connected to the rotating shaft and are disposed on the rotating shaft.

[0009] The baffle plate includes a housing, a spring, a plate body, and a moving shaft. The housing is fixedly connected to the screen plate and located outside the screen plate. The plate body is slidably connected to the housing and passes through the screen plate. The two ends of the spring are respectively connected to the housing and the plate body, and the spring is located inside the housing. The moving shaft is fixedly connected to the plate body and located on one side of the plate body.

[0010] The screening assembly further includes a drive base, which is fixedly connected to the housing and located inside the housing.

[0011] This utility model discloses a pulverizer for producing nano-calcium carbonate. In operation, the first and second rotary motors are started. The first rotary motor drives the rotating plate, the sieve plate, and the baffle plate to rotate, while the two second rotary motors drive the two pulverizing rollers to rotate in opposite directions. At this time, the nano-calcium carbonate to be pulverized is added to the outer casing through the feed hopper and the feed pipe. The nano-calcium carbonate falls along the feed pipe between the two pulverizing rollers, where it is pulverized. The pulverized nano-calcium carbonate falls onto the sieve plate and is sieved, allowing qualified nano-calcium carbonate to pass through the sieve. The unqualified nano-calcium carbonate remains inside the sieve plate. The first rotary motor drives the sieve plate to rotate, causing the unqualified nano-calcium carbonate to rotate as well. The baffle plate prevents the nano-calcium carbonate from slipping off the inside of the sieve plate, thus affecting its lifting. As the sieve plate and baffle plate rotate, the unqualified nano-calcium carbonate gradually rises and rotates to the top of the feed shell. There, under gravity, it falls back into the feed shell and is re-crushed by the crushing roller until it reaches the required particle size standard. This avoids the problem of reduced processing efficiency caused by manually transferring and crushing unqualified nano-calcium carbonate. Attached Figure Description

[0022] This utility model provides a pulverizer for producing nano-calcium carbonate, including a shell 101, a feed pipe 102, and a screening component 104. The screening component 104 includes a rotating plate 105, a screen plate 106, a baffle plate 107, a feed shell 108, a pulverizing component 109, and a collection frame 110. The screening component 104 also includes a stirring component 111. The baffle plate 107 includes a shell 114, a spring 115, a plate 116, and a moving shaft 117. The screening component 104 also includes a drive seat 118. The rotating plate 105 and the screen plate 106 are driven to rotate by a first rotary motor 119, so that the screen plate 106 can drive the unqualified nano-calcium carbonate to rotate, thereby causing the unqualified nano-calcium carbonate to fall back into the feed shell 108 for re-pulverization until it can pass through the sieve holes on the screen plate 106. It can be understood that the above solution can be used to improve the processing efficiency of nano-calcium carbonate, and can also be used to improve the screening efficiency of nano-calcium carbonate.

[0023] In this specific embodiment, the feed pipe 102 is fixedly installed on one side of the outer shell 101 and communicates with the outer shell 101; a feed hopper 103 is provided at the top of the feed pipe 102, and the nano-calcium carbonate to be crushed is conveniently added into the interior of the outer shell 101 through the feed hopper 103 and the feed pipe 102.

[0024] The rotating plate 105 is rotatably connected to the outer shell 101 and located inside the outer shell 101; the sieve plate 106 is fixedly connected to the rotating plate 105 and located on one side of the rotating plate 105; the baffle plate 107 is connected to the sieve plate 106 and disposed on the sieve plate 106; the feed shell 108 is fixedly connected to the outer shell 101 and located inside the outer shell 101 and on the inner side of the sieve plate 106; the crushing component 109 is disposed on the feed shell 108; multiple baffle plates 107 are disposed and evenly distributed on the sieve plate 106; the sieve plate 106 is circular and has sieve holes to screen unqualified nano-calcium carbonate after crushing. The outer casing 101 has a first rotary motor 119 installed on one side. The output end of the first rotary motor 119 passes through the outer casing 101 and is connected to the rotating plate 105. The crushing component 109 includes two crushing rollers 122, which are rotatably installed inside the feed shell 108. The outer casing 101 also has a second rotary motor 120 installed on it. The output end of the second rotary motor 120 passes through the outer casing 101 and the feed shell 108 and is connected to the crushing rollers 122. The feed shell 108 has two guide plates 123 installed on it. The guide plates 123 are used to guide nano-calcium carbonate between the two crushing rollers 122.

[0025] In use, the first rotary motor 119 and the second rotary motor 120 are started. The first rotary motor 119 drives the rotating plate 105, the sieve plate 106, and the baffle plate 107 to rotate, while the two second rotary motors 120 drive the two crushing rollers 122 to rotate in opposite directions. At this time, the nano-calcium carbonate to be crushed is added to the outer shell 101 through the feed hopper 103 and the feed pipe 102. The nano-calcium carbonate falls between the two crushing rollers 122 along the feed pipe 102 and is crushed by the crushing rollers 122. The crushed nano-calcium carbonate falls onto the sieve plate 106 and is screened by the sieve plate 106 so that qualified nano-calcium carbonate can pass through the sieve holes on the sieve plate 106. The substandard nano-calcium carbonate remains inside the sieve plate 106. At this time, the first rotary motor 119 drives the sieve plate 106 to rotate, which in turn causes the sieve plate 106 to rotate the substandard nano-calcium carbonate. The baffle plate 107 prevents the nano-calcium carbonate from sliding off the inside of the sieve plate 106, thus affecting the lifting of the nano-calcium carbonate. As the sieve plate 106 and the baffle plate 107 rotate, the substandard nano-calcium carbonate gradually rises and rotates to the top of the feed shell 108. At this time, the substandard nano-calcium carbonate falls back into the feed shell 108 under the action of gravity, and is then crushed again by the crushing roller 122 until it reaches the required particle size standard. This avoids the problem of reduced processing efficiency caused by manually transferring and crushing substandard nano-calcium carbonate.

[0026] Secondly, the collection frame 110 is connected to the outer shell 101 and is located inside the outer shell 101; the collection frame 110 collects the nano-calcium carbonate that passes through the sieve plate 106.

[0027] Meanwhile, the stirring component 111 includes a rotating shaft 112 and a stirring blade 113. The rotating shaft 112 is rotatably connected to the outer shell 101 and is located inside the outer shell 101. The stirring blade 113 is fixedly connected to the rotating shaft 112 and is disposed on the rotating shaft 112. A third rotary motor 121 is also installed on the outer shell 101. The output end of the third rotary motor 121 passes through the outer shell 101 and is connected to the rotating shaft 112. The third rotary motor 121 drives the rotating shaft 112 to rotate, thereby driving the stirring blade 113 to rotate. This causes the stirring blade 113 to agitate the nano-calcium carbonate falling on the sieve plate 106, thereby improving the sieving efficiency and preventing the accumulation of nano-calcium carbonate from affecting the sieving process.

[0028] In addition, the housing 114 is fixedly connected to the sieve plate 106 and is located outside the sieve plate 106; the plate 116 is slidably connected to the housing 114 and passes through the sieve plate 106; the two ends of the spring 115 are respectively connected to the housing 114 and the plate 116, and the spring 115 is located inside the housing 114; the moving shaft 117 is fixedly connected to the plate 116 and is located on one side of the plate 116.

[0029] Finally, the drive seat 118 is fixedly connected to the housing 101 and is located inside the housing 101.

[0030] Two movable shafts 117 are provided, located on both sides of the plate 116 respectively. Two drive seats 118 are provided, located on both sides inside the outer casing 101 respectively. A force is applied to the plate 116 by the spring 115, allowing the plate 116 to extend out of the casing 114 and thus be positioned inside the sieve plate 106, facilitating the lifting of substandard nano-calcium carbonate. The drive seats 118 are located at the rotating shaft 112 and the stirring blade 113. Since the rotating shaft 112 and the stirring blade 113 are located inside the sieve plate 106, to prevent interference between the rotating shaft 112 and the stirring blade 113, when the sieve plate 106... When rotated, the housing 114, the plate 116, and the moving shaft 117 will rotate. When the moving shaft 117 rotates to the drive seat 118, the drive seat 118 drives the moving shaft 117 to move, which in turn drives the plate 116 to move, causing the plate 116 to squeeze the spring 115 and retract into the housing 114. At this time, there is no interference between the plate 116 and the stirring blade 113. When the plate 116 leaves the drive seat 118, the plate 116 extends again under the action of the spring 115, thereby avoiding the problem of interference between the baffle plate 107 and the stirring blade 113.

[0031] When using the nano-calcium carbonate production pulverizer of this invention, the nano-calcium carbonate to be pulverized is first poured into the feed pipe 102 through the feed hopper 103. The nano-calcium carbonate then falls along the feed pipe 102 between the two pulverizing rollers 122 inside the feed shell 108. Then, the second rotary motor 120 is started to drive the two pulverizing rollers 122 to rotate in opposite directions to pulverize the nano-calcium carbonate. The pulverized nano-calcium carbonate particles then fall onto the sieve plate 106. The sieve holes on the sieve plate 106 screen the material. Qualified nano-calcium carbonate particles pass through the sieve holes and fall into the collection frame 110 below, waiting for further processing or packaging, while unqualified particles... The particles remain inside the sieve plate 106 and are gradually lifted above the feed shell 108 as the sieve plate 106 rotates. During this process, the baffle plate 107 prevents unqualified nano-calcium carbonate particles from sliding off the inside of the sieve plate 106, ensuring that the material can be smoothly lifted above the feed shell 108. After the unqualified nano-calcium carbonate particles are lifted above the feed shell 108, they fall back into the feed shell 108 under the action of gravity and are crushed again by the crushing roller 122. This process is repeated until all particles reach the required particle size standard, thereby avoiding the need for manual transfer of unqualified nano-calcium carbonate particles and improving processing efficiency.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
