Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and in particular to a dispersing and grading device for cement production. Background Technology

[0002] Cement is an important inorganic cementitious material, in powder form, usually made from raw materials such as limestone and clay through high-temperature calcination and grinding. When it comes into contact with water, it undergoes a hydration reaction, gradually hardening and gaining strength, firmly binding aggregates such as sand and stone to form solid concrete or mortar. Cement can be classified into general-purpose cement, special-purpose cement, and specialty cement according to its performance and uses. It is widely used in construction, roads, bridges, and water conservancy projects, and is an indispensable basic material for modern infrastructure construction, playing an important role in promoting economic development and improving people's livelihoods.

[0003] In cement production, dispersing and grading is a crucial step, directly impacting the quality and performance of the cement. However, existing dispersing and grading equipment for cement production typically uses a single dispersing roller to disperse cement raw materials. This simple structure has limited functionality, only capable of basic dispersing operations, resulting in insufficient dispersing. Consequently, agglomerated materials cannot be completely dispersed and enter the grading process. Furthermore, it cannot effectively grade the dispersed materials, failing to meet the particle size distribution requirements for cement production. In addition, dust leakage is prone to occur during the dispersing and grading process, causing material waste, polluting the production environment, and endangering the health of operators.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1:

[0031] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a dispersing and grading device for producing cement, including a support 1, a storage hopper 2 installed on the top of the support 1, a sealing cover 3 installed on the top of the storage hopper 2, a stirring assembly 4 installed inside the storage hopper 2, a fixing frame 5 fixed to the bottom of the storage hopper 2, and a baffle 6 slidably connected to the inner wall of the fixing frame 5, and the position of the baffle 6 corresponds to the position of the discharge port at the bottom of the storage hopper 2.

[0032] The support frame 1 serves as the overall support frame for the equipment, providing a foundation for the installation of other components. This ensures the overall stability and structural integrity of the equipment, allowing each component to be laid out and installed according to design requirements. The storage hopper 2 is used to store the cement raw materials to be processed; it is a temporary storage container for the raw materials before they enter the equipment for dispersing and grading. The sealing cover 3 is installed on top of the storage hopper 2, providing a seal to prevent dust and other impurities from spilling out during raw material storage and processing, ensuring a clean working environment. It also prevents external debris from entering the storage hopper 2 and contaminating the raw materials. It should be noted that the connection between the sealing cover 3 and the storage hopper 2 is made of rubber. The sealing gasket and the mixing component 4 are designed to break up clumps of cement raw materials into uniform granules through their internal structure, preparing them for subsequent grading. The fixing frame 5 provides an installation and sliding track for the baffle 6, allowing it to slide stably at the bottom outlet of the storage hopper 2, thus controlling the discharge. The baffle 6 can control the opening and closing of the bottom outlet of the storage hopper 2 by moving its position, thereby adjusting the discharge flow of cement raw materials to meet different production needs. It should be noted that a rubber sealing strip is provided at the connection between the baffle 6 and the storage hopper 2 to prevent leakage of cement raw materials from this point.

[0033] The inner wall of the support 1 is equipped with a discharge hopper 7, and the inner wall of the discharge hopper 7 is slidably connected to a screening frame 8. The bottom of the screening frame 8 is provided with several sets of screening holes 9, and a storage mechanism 10 is provided below the screening frame 8.

[0034] The discharge hopper 7 is designed to receive the dispersed cement raw materials flowing out from the bottom outlet of the storage hopper 2 and guide them to the screening frame 8 for grading. The screening frame 8 is slidably installed on the inner wall of the discharge hopper 7 and has several sets of screening holes 9 at its bottom to grade and screen the dispersed cement raw materials. Fine particles that meet the aperture requirements of the screening holes 9 will fall through the screening holes 9, while larger particles will remain in the screening frame 8, thus achieving the separation of raw materials of different particle sizes. When the screening frame 8 contains larger cement raw materials, it can be removed from the discharge hopper 7, and the sealing cover 3 can be opened to pour the cement raw materials in the screening frame 8 back into the storage hopper 2 for secondary dispersing.

[0035] The mixing assembly 4 includes a first dispersing roller 41 and a second dispersing roller 42 respectively disposed inside the storage hopper 2. One end of the first dispersing roller 41 and the second dispersing roller 42 are rotatably connected to the inner wall of the storage hopper 2 through a flange, and the first dispersing roller 41 and the second dispersing roller 42 are designed to be staggered.

[0036] The first dispersing roller 41 and the second dispersing roller 42 are the core components for dispersing cement raw materials. Through their staggered structural design, when the raw materials pass between them, they are subjected to compression, shearing and friction forces in different directions, thereby breaking up the clumped cement raw materials into uniform particles, preparing them for subsequent grading.

[0037] Example 2:

[0038] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the storage mechanism 10 includes a base plate 101 fixed to the inner wall of the support 1, a placement frame 102 fixed to the top of the base plate 101, and a storage frame 103 slidably connected to the inner wall of the placement frame 102.

[0040] The base plate 101 is fixed to the inner wall of the bracket 1 to provide a stable support foundation for the placement frame 102. The placement frame 102 is set to provide installation and placement space for the storage frame 103, so that the storage frame 103 can be stably placed inside the equipment. The storage frame 103 is set to collect fine cement raw materials screened from the screening frame 8, which facilitates subsequent storage and further processing. It should be noted that a rubber sealing strip is set at the connection between the storage frame 103 and the placement frame 102 to prevent cement raw materials from leaking from here.

[0041] Specifically, a fixed frame 11 is installed on one side of the storage hopper 2, and an installation frame 12 is installed on the top of the sealing cover 3. The outer side of the installation frame 12 is rotatably connected to the outer side of the fixed frame 11 through a connecting plate.

[0042] The fixing bracket 11 is rotatably connected to the mounting bracket 12 via a connecting plate, providing support and connection points for the opening and closing of the sealing cover 3, allowing the sealing cover 3 to rotate around the connection point with the fixing bracket 11 to realize the opening and closing operation of the sealing cover 3. The mounting bracket 12 is rotatably connected to the outside of the fixing bracket 11 via the connecting plate, and is also connected to the snap-fit ​​block 14 via the fixing bolt 15, serving to connect the sealing cover 3 and the fixing bracket 11, ensuring the stability and sealing of the sealing cover 3 when closed.

[0043] Specifically, two sets of support blocks 13 are rotatably connected to the other side of the storage hopper 2. A snap-fit ​​block 14 is rotatably connected to the top of the support block 13. A fixing bolt 15 is threadedly connected to the inner wall of the snap-fit ​​block 14, and the outer side of the fixing bolt 15 is threadedly connected to the inner wall of the mounting bracket 12.

[0044] The support block 13 is provided to provide rotational support for the snap-fit ​​block 14, allowing the snap-fit ​​block 14 to rotate within a certain range, facilitating connection and fixing with the mounting frame 12. The snap-fit ​​block 14 is connected to the fixing bolt 15 through the inner wall thread and is also connected to the inner wall thread of the mounting frame 12, which can realize the firm connection between the sealing cover 3 and the storage hopper 2, ensuring that the sealing cover 3 can effectively seal the storage hopper 2 when closed.

[0045] Example 3:

[0046] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a support base 16 is installed on the outside of the bracket 1, and a horizontally arranged motor 17 is installed on the top of the support base 16.

[0048] The support base 16 is provided to provide a stable support foundation for the motor 17, so that the motor 17 can be firmly installed on the equipment and ensure the stability of the motor 17 during operation. The motor 17 serves as a power source to provide power for the rotation of the first dispersing roller 41, and drives the first gear 18 to rotate through the output end, thereby driving the entire dispersing assembly to work and realize the dispersing treatment of cement raw materials.

[0049] Specifically, a first gear 18 is fixed to the output end of the motor 17, and the shaft of the first gear 18 is fixedly connected to one end of the first dispersing roller 41 through a flange. A gear belt 19 is meshed with the outer side of the first gear 18, and a second gear 20 is meshed with the inner wall of the gear belt 19. The shaft of the second gear 20 is fixedly connected to one end of the second dispersing roller 42 through a flange. Limiting discs 21 for preventing the gear belt 19 from deviating are fixed on both sides of the first gear 18 and the second gear 20.

[0050] The first gear 18 can rotate under the drive of the motor 17, and simultaneously drive the second gear 20 to rotate via the gear belt 19. The gear belt 19 is designed to transmit power, transferring the rotation of the first gear 18 to the second gear 20. The second gear 20 can rotate under the drive of the first gear 18, thereby driving the second dispersing roller 42 to rotate and cooperate with the first dispersing roller 41 to complete the dispersing of cement raw materials. The limiting plate 21 is designed to prevent the gear belt 19 from deviating from the gear during transmission, ensuring stable meshing between the gear belt 19, the first gear 18, and the second gear 20. To ensure the reliability and stability of power transmission, during use, the first gear 18 rotates under the drive of the motor 17. The first gear 18 drives the first dispersing roller 41 to rotate and at the same time drives the gear belt 19 to rotate. The gear belt 19 drives the second gear 20 to rotate, and the second gear 20 drives the second dispersing roller 42 to rotate. At this time, the first dispersing roller 41 and the second dispersing roller 42 rotate in a staggered manner. When the raw material passes between them, it can be subjected to compression, shearing and friction forces in different directions, thereby breaking the lumpy cement raw material into uniform particles.

[0051] Specifically, a cylinder 22 is fixed to the inner wall of the bracket 1, and a connecting seat 23 is fixed to the bottom of the baffle 6, with the outer side of the connecting seat 23 rotatably connected to the piston rod of the cylinder 22.

[0052] The cylinder 22 drives the baffle 6 to slide within the fixed frame 5 through the extension and retraction of the piston rod, thereby controlling the opening and closing of the discharge port of the storage hopper 2 and adjusting the discharge flow rate. The connecting seat 23 is rotatably connected to the piston rod of the cylinder 22, serving to connect the baffle 6 and the cylinder 22, allowing the piston rod of the cylinder 22 to drive the baffle 6 to slide through the connecting seat 23. It should be noted that the cylinder 22 is used in conjunction with an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and a flow control valve. During use, the air compressor compresses ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure, then delivers it to the control valve through an air pipe. The directional control valve switches the airflow channel according to an electrical signal to determine the extension and retraction direction of the cylinder 22. The flow control valve adjusts the airflow speed and controls the movement speed of the cylinder 22. Compressed air enters the rod chamber or rodless chamber of the cylinder 22, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion.

[0053] Specifically, the inner wall of the discharge hopper 7 is fixed with a ramp strip 24 and a support strip 25, and the bottom of the ramp strip 24 is slidably connected to the top of the screen frame 8, and the top of the support strip 25 is slidably connected to the bottom of the screen frame 8.

[0054] The ramp strip 24 provides support and guidance for the screening frame 8, allowing it to slide stably within the discharge hopper 7. Furthermore, its ramp design helps guide cement raw materials smoothly into the screening frame 8 for screening. The support strip 25 provides bottom support for the screening frame 8, ensuring its stability during the screening process and preventing it from shaking or tilting due to the impact of the raw materials, thus affecting the screening effect.

[0055] Working Principle: When this cement dispersing and grading equipment is in operation, the sealing cover 3 is first opened, and the cement raw material to be processed is poured into the storage hopper 2. Then, the sealing cover 3 is tightened and secured using a fixing frame 11, mounting frame 12, support block 13, snap-fit ​​block 14, and fixing bolts 15. Next, the motor 17 is started, driving the first gear 18 to rotate. The first gear 18, through a gear belt 19, drives the second gear 20 to rotate synchronously. Since the first gear 18 is fixedly connected to the first dispersing roller 41 and the second gear 20 to the second dispersing roller 42 via flanges, the first and second dispersing rollers 41 and 42 begin to rotate, and since they are staggered, they can fully disperse the cement raw material in the storage hopper 2. The dispersed raw material reaches the bottom of the storage hopper 2, and the machine is then started. The cylinder 22 piston rod drives the baffle 6 to slide within the fixed frame 5 via the connecting seat 23, controlling the opening of the discharge port so that the raw material falls into the screening frame 8 in the discharge hopper 7. Since the bottom of the screening frame 8 is provided with several screening holes 9, fine particles smaller than the aperture of the screening holes 9 fall through the screening holes 9, while coarse particles larger than the aperture remain in the screening frame 8. At the same time, the inclined bar 24 and the support bar 25 support and guide the screening frame 8 from the top and bottom respectively, ensuring that the screening frame 8 slides stably for screening. The falling fine particles enter the storage mechanism 10, pass through the placement frame 102 fixed on the bottom plate 101 in sequence, and finally fall into the storage frame 103 slidably connected within the placement frame 102 for storage. The coarse particles remaining in the screening frame 8 can be further dispersed to achieve the dispersion and grading of cement raw materials.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
