Description

Technical Field

[0001] The invention relates to the technical field of cement production, and in particular to a cement grinding particle size detection system. Background Art

[0002] In the cement manufacturing process, cement grinding is an important link that determines the quality and performance of cement. The purpose of cement grinding is to grind clinker, gypsum and other additives to an appropriate fineness to ensure that the hydration reaction of cement is fully carried out, thereby achieving the expected strength and durability. The uniformity and fineness of particle size are important indicators of cement performance, so particle size detection technology occupies an important position in cement production.

[0003] Sieving is a classic and widely used technology for cement powder particle size detection. It uses sieves with different apertures to separate powder particles to determine their particle size distribution. This method is simple to operate and low-cost, and is suitable for particle detection in various particle size ranges. The sieving method is based on the different particle sizes. The powder is passed through a series of sieves with different apertures through vibration or other mechanical forces. Smaller particles pass through the sieves, while larger particles are retained on the sieves. The particle size distribution of the powder is obtained by weighing the residue on each sieve and calculating the mass percentage of each particle size.

[0004] In the screening process of cement grinding particle size detection, if too much material is placed in the screen at one time, it will have a negative impact on the screening efficiency and the accuracy of the results. Too much material will cause the screen holes to be blocked, reduce the screening efficiency, make it difficult for fine particles to pass through the screen, and thus affect the accuracy of the particle size distribution data. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] refer to Figure 1-Figure 7 , a cement grinding particle size detection system, comprising:

[0041] A detection bracket 100, on which a feed tank 101 is provided;

[0042] A box body 102 is arranged on the detection bracket 100, and the box body 102 is located at the bottom of the feed tank 101;

[0043] A plurality of screening tanks 103 are arranged on the outer wall of the box body 102, and screening nets 104 are respectively arranged on the outer wall, top and bottom of the screening tank 103, and the screening net 104 at the bottom of the screening tank 103 is threadedly connected to the screening tank 103;

[0044] A connecting pipe 105 is provided between the feed tank 101 and the screening tank 103, the top of the connecting pipe 105 is connected to the feed tank 101, and the bottom of the connecting pipe 105 passes through the screening net 104 on the top of the screening tank 103 and is connected to the screening tank 103;

[0045] A vibration component for moving the screening tank 103 up and down is provided between the box body 102 and the screening tank 103;

[0046] A release component provided between the box body 102 and the connecting tube 105, used for opening and closing the connecting tube 105;

[0047] Wherein, the release component can open the connection pipe 105 for a preset time when the vibrating component moves the screening tank 103 up and down for a preset number of times;

[0048] Wherein, the vibrating component can rotate the screening tank 103 by a preset angle while moving the screening tank 103 up and down;

[0049] By setting up the feed tank 101, the cement powder particles that need to be tested for particle size can be sampled in the feed tank 101. When in use, the operator can start the vibration component, and the vibration component moves up and down the position of the screening tank 103, which can make the screening tank 103 vibrate. When the screening tank 103 moves up and down to a preset number of times, the connecting pipe 105 can be opened for a preset time. At this time, part of the cement powder in the feed tank 101 can enter the screening tank 103 through the connecting pipe 105. In specific applications, the screening nets 104 on the multiple screening tanks 103 can be set with different diameter meshes to correspond to particles of different particle sizes. The sieving tank 103 can be used to collect particles. The up and down movement of the sieving tank 103 generates vibrations, which can sieve the cement powder entering the sieving tank 103, shake out the powder smaller than the mesh diameter from the sieving tank 103, and retain the cement particles larger than the mesh diameter in the sieving tank 103 to achieve particle collection. Multiple sieving tanks 103 work at the same time, and can quickly complete multi-stage screening. The sieving nets 104 of the multiple sieving tanks 103 have different apertures, and can grade and screen samples of different particle sizes. After the screening is completed, the operator can collect samples of different particle sizes in each sieving tank 103 respectively, and obtain water content by analyzing the samples of each particle size. The particle size distribution of the mud powder grinding particles can be determined to guide production and quality control. Furthermore, the set release component can open the connecting pipe 105 for a preset time when the vibrating component moves the screening tank 103 up and down for a preset number of times. When the screening work is in progress, the connecting pipe 105 is intermittently opened to release a part of the cement powder to ensure that during screening, for a large amount of cement powder sample to be tested, a large amount of cement powder will not be poured into the screening tank 103, so as to avoid the particles in the screening tank 103 being unable to jump due to a large amount of powder, thereby affecting the screening efficiency, thereby improving the screening accuracy and efficiency. In addition, during the vibration While the components move the screening tank 103 up and down, the screening tank 103 can also rotate at a preset angle. When the particles stored in the screening tank 103 gradually increase, the new batch of powder will be on the top of the original particles. During the up and down movement of the screening tank 103, the new batch of powder will hit the screening net 104 on the top of the screening tank 103. The rotation of the screening tank 103 can provide centrifugal force for the powder and particles, allowing the powder and particles to hit the side wall of the screening tank 103 and the filter net on the side wall, so that the powder and particles are more evenly distributed when hitting the side wall of the screening tank 103, and further screened by the screening net 104 on the side wall. This rotational movement not only improves the screening efficiency, but also effectively reduces the accumulation of particles, ensuring the comprehensiveness and uniformity of each screening, thereby further improving the accuracy and efficiency of the screening, and solving the problem that too much material is put into the screen at one time in the prior art, which will have a negative impact on the screening efficiency and the accuracy of the results. Too much material will cause the screen holes to be blocked, reducing the screening efficiency and making it difficult for fine particles to pass through the screen, thus affecting the accuracy of the particle size distribution data.

[0050] As a further solution of the present invention, the vibration component includes a connecting boss 200 provided on one side of the screening tank 103, the connecting boss 200 extends into the box body 102 and is slidably connected to the box body 102, a turntable 201 is rotatably connected in the box body 102, and a top contact boss 202 is connected to the top of the turntable 201;

[0051] By setting the turntable 201, when in use, the operator can rotate the turntable 201. The rotation of the turntable 201 can drive the top contact boss 202 on its top to rotate. When the top contact boss 202 rotates to a preset angle, it can contact the connecting boss 200, and can press the connecting boss 200 to move the connecting boss 200 upward. The connecting boss 200 can drive the screening tank 103 to move upward. When the top contact boss 202 leaves the connecting boss 200, the screening tank 103 is reset downward by gravity, thereby achieving the purpose of moving the screening tank 103 up and down to generate vibration.

[0052] As a further solution of the present invention, the outer wall of the screening tank 103 is connected with a connecting ring 203, and the connecting ring 203 is slidably connected to the connecting boss 200;

[0053] By providing the connection ring 203 , the connection ring 203 can connect the screening tank 103 with the connection boss 200 .

[0054] As a further solution of the present invention, a connecting shaft 204 connected to the screening net 104 at the top of the screening tank 103 is provided at the bottom of the connecting pipe 105, and a first spring 205 is provided between the connecting shaft 204 and the connecting pipe 105;

[0055] By setting the connecting shaft 204, when the screening tank 103 moves upward, the connecting shaft 204 can ensure the connection between the connecting pipe 105 and the screening tank 103, and the first spring 205 can generate potential energy when the screening tank 103 moves upward, which is convenient for the subsequent resetting of the screening tank 103. In addition, the elastic force of the first spring 205 can also provide assistance when the screening tank 103 moves downward, enhance the vibration effect, and thus improve the screening efficiency. When the vibrating component drives the screening tank 103 to move up and down, the elastic potential energy of the first spring 205 can effectively buffer the vibration impact, protect the structural integrity of the screening device, and extend the service life of the equipment. During the up and down movement of the screening tank 103, the stable connection between the connecting shaft 204 and the connecting pipe 105 avoids the problems of powder leakage and reduced screening accuracy. This design enables the screening tank 103 to work stably and continuously during the vibration process, ensuring that the cement powder is fully graded and screened during the screening process. Finally, through the particle size analysis of each screening tank 103, the particle size distribution of the cement powder particles can be accurately obtained, thereby guiding production and quality control and improving the quality and performance of cement products.

[0056] As a further solution of the present invention, a gear 206 is slidably connected to the connecting shaft 204, a connecting frame 207 rotatably connected to the gear 206 is connected to the box body 102, and a rack 208 meshing with the gear 206 is slidably connected to the connecting frame 207;

[0057] By setting the gear 206, the connecting frame 207 can limit the position of the gear 206. When the screening tank 103 moves upward, the connecting shaft 204 can slide in the gear 206. When the screening tank 103 needs to be rotated, the position of the movable rack 208 can allow the screening tank 103 to rotate with the connecting shaft 204 as the center. Through this design, the screening tank 103 can not only move up and down during the vibration process, but also rotate when needed, further enhancing the screening effect. The rotating action makes the powder and particles more evenly distributed in the screening tank 103, avoiding the accumulation of particles on one side of the screening tank 103, thereby improving the uniformity and accuracy of the screening. At the same time, the rotation can also promote the contact between the particles and the screen, enhance the efficiency of the particles passing through the screen, and further improve the screening efficiency.

[0058] As a further solution of the present invention, a top rod 209 is connected to the top of the connecting boss 200, a top contact block 210 is connected inside the rack 208, and a second spring 211 is connected between the rack 208 and the connecting frame 207;

[0059] By setting the push rod 209, when the connecting boss 200 moves upward to allow the screening tank 103 to move upward, the push rod 209 moves upward to press the top contact block 210, and the top contact block 210 is forced to move to drive the rack 208 to move, and the rack 208 can rotate the connecting shaft 204 through the gear 206, and the rotation of the connecting shaft 204 can drive the screening tank 103 to rotate. When the connecting boss 200 is reset downward, the push rod 209 leaves the top contact block 210, and the rack 208 is reset by the force of the second spring 211, so that the screening tank 103 can be reset and rotated. This design ensures that the screening tank 103 can perform necessary rotation operations while moving up and down, so that the materials in the screening tank 103 can be fully vibrated and screened. Through the cooperation of the push rod 209 and the top contact block 210, the rotation action is automatically triggered each time the screening tank 103 rises, further optimizing the screening effect. The precise meshing of the rack 208 and the gear 206 makes the rotation of the screening tank 103 stable and controllable, avoiding possible deviation or instability during the rotation process.

[0060] As a further solution of the present invention, the release component includes a blocking frame 300 disposed in the feed tank 101, the blocking frame 300 can close the top of the connecting pipe 105, the bottom of the blocking frame 300 extends to the bottom of the feed tank 101, and a third spring 301 is connected between the blocking frame 300 and the feed tank 101;

[0061] By setting the third spring 301, the third spring 301 can limit the position of the sealing frame 300, so that the sealing frame 300 can close the top of the connecting pipe 105, thereby avoiding the overflow of cement powder. When screening is required, the screening tank 103 moves downward to drive the sealing frame 300 to move downward, so that the top of the connecting pipe 105 is opened, and the cement powder can smoothly enter the connecting pipe 105 and enter the screening tank 103 for screening operations.

[0062] As a further solution of the present invention, a rotating shaft 302 is rotatably connected to the box body 102, the rotating disk 201 is connected to the rotating shaft 302, a reciprocating screw rod 303 is connected to the rotating shaft 302, a moving ring 304 is threadedly connected to the reciprocating screw rod 303, a limiting tube 305 is connected to the top of the moving ring 304, and a limiting rod 306 slidably connected to the limiting tube 305 is connected to the top of the box body 102;

[0063] By setting the reciprocating screw rod 303, when in use, the rotating shaft 302 can be rotated, and the rotation of the rotating shaft 302 can move the position of the moving ring 304 upward through the reciprocating screw rod 303. When the moving ring 304 moves upward to a preset position, it can contact the blocking frame 300 at the bottom of the feeding tank 101. When the connecting ring 203 continues to move upward, it can touch the position of the closing frame, allowing the closing frame to move upward and away from the connecting pipe 105, so as to achieve the purpose of opening the connecting pipe 105. When the rotating shaft 302 continues to rotate, the reciprocating screw rod 303 rotates to move the moving ring 304 to the extreme position, and then starts to move downward, so as to reset the closing frame, so as to achieve the purpose of closing the connecting pipe 105.

[0064] As a further solution of the present invention, the top of the rotating shaft 302 extends into the feed tank 101 and is connected to a plurality of blades 307;

[0065] By providing the blades 307, the cement powder in the feed tank 101 can be stirred when the shaft 302 rotates, preventing the powder from agglomerating and settling in the feed tank 101, thereby ensuring that the cement powder enters the connecting pipe 105 evenly, and improving the accuracy and efficiency of screening. The stirring action of the blades 307 can keep the powder in the feed tank 101 in a flowing state, ensuring that the powder can be smoothly transported to the screening tank 103 when the connecting pipe 105 is opened, and preventing the powder from clogging the connecting pipe 105.

[0066] As a further solution of the present invention, the detection bracket 100 is connected to a motor 308, and the driving shaft of the motor 308 is connected to the rotating shaft 302;

[0067] By setting the motor 308 , the setting of the motor 308 can provide driving force for the rotation of the rotating shaft 302 .
