Description

Technical Field

[0001] The invention relates to the field of building production, in particular to a cement clinker performance detection device. Background Art

[0002] In the field of modern construction engineering, cement is a key basic material. Its quality is directly related to the safety and durability of buildings. Cement clinker is the core intermediate product in the cement production process. Its performance plays a decisive role in the quality of cement products. The fineness of cement clinker affects the hydration rate and strength development of cement. Therefore, when using it, it is necessary to use a detection device to measure the fineness of cement clinker to control it within an appropriate range, which helps to judge the quality and uniformity of the clinker.

[0003] The steps for traditional cement clinker fineness detection are as follows: first accurately weigh an appropriate amount of cement clinker sample and place it in a clean negative pressure sieve, cover the sieve cover and place it on the sieve seat, turn on the sieving instrument for 2 minutes, if there is a sample attached to the sieve cover, tap it to make it fall off, after the sieving is completed, weigh all the sieve residues with a balance, and then calculate the proportion of coarse particles remaining on the sieve to the total amount of cement based on the mass of the sieve residue and the mass of the sample, so as to reflect the fineness of the cement clinker. If the ratio is high, there are more coarse particles and the fineness is coarse, otherwise it is fine. This test result is extremely critical to accurately control the quality of cement production and optimize product performance, because it affects the hydration reaction characteristics and strength development of cement in subsequent applications.

[0004] There are certain defects in the process of cement clinker performance detection device: during the screening process, cement clinker is partially screened on the screen. As the cement clinker becomes clogged in the aperture of the screen and the screening time is long, the degree of blockage increases, the screening efficiency will gradually decrease, and the number of fine particles passing through the screen will decrease, resulting in an increase in the measured mass of the screen residue, making the calculated fineness larger than the actual value, and the screen blockage situation is difficult to maintain consistency in each test, which increases the uncertainty of the measurement results. Secondly, during the screening process, part of the cement clinker sample will adhere to the top of the screen cover and the side walls of the drying seat. Even if it is tapped to make it fall, it may not be possible to completely guarantee that all attached samples can return to the screen to participate in the screening, thereby affecting the accuracy of the measurement results.

[0005] Therefore, it is necessary to propose a cement clinker performance detection device to solve the above technical problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a cement clinker performance detection device, which solves the technical problems that when the cement clinker performance detection device is screened, the screen is easily blocked locally, resulting in reduced screening efficiency, increased mass of screen residue, resulting in a larger calculated value of fineness, and the blockage situation is difficult to be consistent, increasing measurement uncertainty; at the same time, the samples are attached to the side walls of the screen cover and the screen seat and it is difficult to fully return to the screen, affecting the measurement accuracy.

[0014] Preferably, one end of the second injection hole is aligned with the conical shape of the screen cover.

[0015] The present invention has achieved the following beneficial effects: (1) The present invention sets an anti-blocking component. When the anti-blocking plate rotates, it pushes the first cleaning brush that repel each other, driving the rotating rod to rotate slowly. The rotating rod drives the first cleaning brush to use the brush to clean the screen sample to prevent fine particles from accumulating and clogging the screen. The anti-blocking plate rotates to block part of the screen channel, changing the distribution of fine particles, making the screening of other parts of the screen smoother, preventing the entire screen from being blocked, and ensuring continuous and stable screening. The first cleaning brush cleans in real time, and fine particles on the screen can be brushed off as soon as they tend to accumulate, keeping the screen transparent. Compared with traditional devices, there is no need to wait for the screening to end and deal with the blockage, reducing the measurement error caused by the blockage. When the base moves up and down, the gap between the anti-blocking plate and the screen changes, and the particles that cause the blockage can be cleaned under the action of negative pressure. This synergistic effect makes the anti-blocking system of the screen more perfect, and it can operate more stably in each detection, reducing the uncertainty of the measurement results caused by the difference in the blockage of the screen.

[0016] (2) The present invention sets a cleaning component. When the first cleaning brush rotates, the second cleaning brush is linked to rotate. Due to the special structure of the second cleaning brush, it can fit tightly against the side wall of the sieve seat and the top wall of the sieve cover. The friction of the bristles is used to automatically scrape and clean the sample without additional power. The sample adhering to the side wall and the top wall is effectively removed to prevent it from falling and affecting the screening result, thereby ensuring the accuracy of the screening. The compressed gas machine sprays gas intermittently, and the gas is sprayed out through the second injection pipe and the second injection hole on the driving seat in turn. The rotation of the rotating rod drives the driving seat to rotate and the threaded seat is hollow to assist, so that the gas is blown from the second injection holes at different angles along the conical shape of the sieve cover and the vicinity of the sieve seat. The sample that falls back on the sieve is removed in time, the interference with the screening is reduced, the screening environment is maintained stable, and the screening quality is improved. One end of the second injection hole is along the conical shape of the sieve cover, so that the gas can better fit the inner surface and cover the entire inner surface, thereby reducing cleaning dead corners and enhancing the coverage range.

[0017] (3) The present invention sets a back-blowing assembly. When the base moves up and down and the anti-blocking plate rotates, the compressed gas machine is started to allow gas to be ejected from the first injection hole, and the position of the injection hole changes accordingly. The compressed gas machine can be used to clean the different positions of the screen. The compressed gas machine works intermittently to clean the blockage of the screen while avoiding interference with the screening process, thereby ensuring a stable screening environment and accurate measurement results, enhancing the anti-blocking effect, and more effectively avoiding blockage of the screen.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, a cement clinker performance detection device comprises a detection box 1 and a dust suction device, an open slot is provided on the top of the detection box 1, a base 11 is provided on the top of the detection box 1 and in the open slot, a suction hole 111 in a ring array is provided on the bottom wall of the base 11, a suction pipe 112 connected to the suction hole 111 is fixedly connected below the base 11, an end of the suction pipe 112 away from the base 11 is connected to the dust suction device, the base 11 is opened upward, a sieve seat 12 is provided on the top of the base 11, and a sieve cover 13 is provided on the top of the sieve seat 12, when cement clinker is sieved on the sieve, the dust suction device can timely suck away fine particles on the sieve through the suction holes 111 and the suction pipe 112 on the base 11; like Figure 3-Figure 5As shown, the anti-blocking component 2 is arranged inside the base 11 and is used to prevent the screen inside the screen seat 12 from being blocked. The anti-blocking component 2 includes: a motor 21, which is installed on the bottom wall of the open groove through the motor 21 seat; a linkage seat 22, which is fixedly installed on the bottom wall of the open groove; a linkage hole 23, which is opened in the inner cavity at the top of the linkage seat 22; two bevel gears 24, which are meshed and rotatably connected to the linkage hole 23, and the output end of the motor 21 is fixedly connected to the middle of one of the bevel gears 24; a transmission rod 25, which One end rotates through the inside of the linkage seat 22 and is fixedly connected to the middle of another bevel gear 24, and the other end of the transmission rod 25 slides through the inside of the base 11; the anti-blocking plate 26, which is a semi-arc-shaped structure, is arranged below the sieve seat 12 and is close to each other; the rotating rod 27 is arranged in the middle of the lower part of the sieve cover 13; the first cleaning brush 28 is plugged and installed below the rotating rod 27, and the brush on the first cleaning brush 28 is close to the sieve net in the sieve seat 12; the anti-blocking plate 26 and the first cleaning brush 28 are arranged to repel each other; It should be noted that when it is detected that the screen inside the screen seat 12 is clogged with fine particles, the motor 21 is started, and its output end drives one of the bevel gears 24 to rotate, and the other bevel gear 24 drives the transmission rod 25. The rotation of the moving rod will drive the anti-blocking plate 26 to rotate. Due to the action of the dust suction device, the inside of the base 11 is in a negative pressure state, and the gas enters the inside of the base 11. In this case, the anti-blocking plate 26 rotates slowly as a whole in the screen, which can block part of the screening channels of the screen. This makes the screening of other unblocked parts of the screen more effective, because the fine particles that may have been blocked in these channels will be redistributed under the action of the anti-blocking plate 26, avoiding local excessive blockage, thereby improving the screening effect; When the anti-blocking plate 26 rotates, it pushes the first cleaning brush 28. Since the anti-blocking plate 26 and the first cleaning brush 28 are arranged to repel each other, the first cleaning brush 28 and the rotating rod 27 will slowly rotate in the sieve seat 12 under the push of the anti-blocking plate 26. During the screening process, the rotating rod 27 drives the first cleaning brush 28 to evenly clean the sample on the sieve with the brush to prevent fine particles from accumulating on the sieve and clogging the sieve. The rotation of the anti-blocking plate 26 can block part of the channels of the screen. This method changes the distribution of fine particles on the screen. In the traditional screening process, fine particles are easily accumulated and blocked in certain local areas of the screen, resulting in a decrease in screening efficiency. The anti-blocking plate 26 uses its own characteristics to block part of the channels. The air pressure is greater in another area, which redistributes the fine particles and makes the screening of other parts of the screen smoother, effectively preventing the blockage of the entire screen and ensuring the continuity and stability of the screening process. The first cleaning brush 28 cleans the screen in real time under the drive of the anti-blocking plate 26. During the screening process, once the fine particles on the screen tend to accumulate, the first cleaning brush 28 can brush them off, so that the screen always maintains a good transparent state. Compared with traditional devices, there is no need to wait until the screening is completed to deal with the blockage problem, reducing the measurement error caused by blockage.

[0023] like Figure 4 and Figure 6 As shown, a threaded seat 29 is provided at the top of the rotating rod 27 , and the threaded seat 29 is threadedly connected below the screen cover 13 .

[0024] It should be noted that the threaded connection method allows the rotating rod 27 to be easily installed under the sieve cover 13. The staff only needs to align the threaded seat 29 on the top of the rotating rod 27 with the threaded part under the sieve cover 13, and then rotate the rotating rod 27 to firmly install it in place. This is very beneficial for the maintenance and servicing of the equipment, and can reduce the time and workload of equipment maintenance. At the same time, the position of the rotating rod 27 under the sieve cover 13 can be fine-tuned to achieve the best fit between the first cleaning brush 28 and the screen.

[0025] like Figure 3 , Figure 7 and Figure 8As shown, the vibration assembly 211 is arranged on the bottom wall of the open groove, and the vibration assembly 211 includes: a limit rod 212, which is provided in two groups, and each group is four, and the lower parts of the two groups of limit rods 212 are symmetrically installed on the bottom wall of the open groove; a support plate 2121, which is fixedly installed on the top of the limit rod 212, and a round hole is opened in the middle; a bearing seat 213, which is provided in two groups, and one group is two, and the lower parts of the two groups of bearing seats 213 are symmetrically installed on the bottom wall of the open groove; a cam 214, which is rotatably connected between a group of bearing seats 213; a movable plate 215, which is slidably connected to the top of a group of limit rods 212, and a connecting rod passing through the inner side of the round hole is fixedly connected to the top of the connecting rod, and the connecting rod is fixed to the bottom of the base 11 fixed connection; an extrusion wheel 216, which is rotatably connected under the movable plate 215 and is tightly attached to the side wall of the cam 214; a driving roller 217, which is rotatably connected to the side wall of the bearing seat 213 and is fixedly connected to the cam 214; a transmission roller 218, of which there are two, and the two transmission rollers 218 are both installed at the end of the linkage seat 22 away from the motor 21, and are fixedly connected to the bevel gear 24 connected to the output end of the motor 21, and a transmission belt is connected between the driving rollers 217 and the two transmission rollers 218 located at the left and right ends, and a compression spring 219, of which there are two groups, one group is one, and the two groups of compression springs 219 are connected between the movable plate 215 and the open slot.

[0026] It should be noted that when the anti-blocking component 2 is used to start the motor 21, the motor 21 drives the bevel gear 24 to rotate. Since the transmission roller 218 is fixedly connected to the bevel gear 24 connected to the output end of the motor 21, the rotation of the bevel gear 24 will drive the transmission roller 218 to rotate synchronously, and the rotation of the transmission roller 218 will drive the driving roller 217 to rotate through the transmission belt. The rotation of the driving roller 217 will cause the cam 214 to rotate synchronously. When the raised part of the cam 214 pushes the extrusion wheel 216, the movable plate 215 will move downward, and the compression spring 219 will be compressed to store elastic potential energy. When the raised part of the cam 214 rotates, the compression spring 219 will be compressed to store elastic potential energy. The spring 219 releases elastic force to push the movable plates 215 on both sides to move upward, so that the movable plates 215 can move up and down, and the base 11 can also be driven to move up and down synchronously through the connecting rod. When the movable plate 215 moves upward, its top will impact the support plate 2121, and its bottom will impact the bearing seat 213. Therefore, the impact of the movable plate 215, the support plate 2121 and the bearing seat 213 will cause the base 11 to vibrate, and then transmit the vibration to the screen seat 12 and the screen, thereby effectively reducing the occurrence of screen blockage. The base 11 generates up and down vibrations, and the anti-blocking plate 26 is arranged under the sieve seat 12 and is in close contact with each other. As the base 11 moves up and down, the relative position between the anti-blocking plate 26 and the sieve is constantly changing. When the base 11 moves upward, the anti-blocking plate 26 and the sieve are just in close contact. When the base 11 moves downward, the anti-blocking plate 26 will create gaps on the sieve. At this time, the particles will be on the surface of the anti-blocking plate 26. Under the action of negative pressure, the particles are more easily sucked into the base 11, so that the particles that may cause the sieve to be blocked can be cleaned in time to prevent them from staying on the sieve for a long time and further blocking the sieve.

[0027] like Figure 4 As shown, in order to further screen better on the base 11, ultrasound is provided on the side wall of the sieve seat 12, and an L-shaped hole is opened on the outer side of the base 11 to facilitate ultrasound to pass through its horizontal end and then be inserted into its horizontal end for fixing. The high-frequency vibration generated by the ultrasonic device when it is working can be transmitted to the screen and cement clinker particles, so that the particles remain dispersed, which is conducive to the smooth passage of fine particles through the screen.

[0028] like Figure 4 and Figure 5 As shown, a back-blowing assembly 221 is provided in the anti-blocking plate 26, and the back-blowing assembly 221 includes: a compressed gas machine 222, which is installed below the linkage seat 22; a first injection pipe 223, which is plugged and installed in the output port of the compressed gas machine 222, and the end of the first injection pipe 223 away from the linkage seat 22 is rotatably connected to the bevel gear 24 through a rotating joint, and a gas hole is opened in the transmission rod 25; a first injection hole 224, which is opened at the top of the anti-blocking plate 26, and is connected to the gas hole in the transmission rod 25.

[0029] It should be noted that when the base 11 moves up and down, the compressed gas machine 222 is started, which can suck in and pressurize the external gas, so that the gas enters the first injection pipe 223. The gas entering through the rotary joint can enter the gas hole inside the transmission rod 25 along the first injection pipe 223, and then be ejected from the first injection hole 224. In this process, as the base 11 moves up and down and the anti-blocking plate 26 rotates, the position of the injection hole is also constantly changing, so that the injection operation can be performed on different positions of the screen. It is worth noting that the compressed gas machine 222 works intermittently. The intermittent operation can avoid excessive interference with the screening process while clearing the blockage of the screen, so that the screening can be carried out in a relatively stable environment, ensuring the accuracy of the measurement results.

[0030] The gas ejected by the back-blowing component 221 can blow these attached particles away from the screen and return them to the screening process, further effectively preventing the accumulation of particles on the screen and keeping the screen unobstructed. This jet cleaning method cooperates with the rotation of the anti-blocking plate 26 mentioned above and the vibration generated by the vibration component. When the anti-blocking plate 26 rotates, it can change the airflow environment under the screen, and the jet can further enhance the cleaning effect of the particles under the screen on this basis. At the same time, the vibration component keeps the particles in an active state, and the jet can better blow these active particles away from the screen, forming a coordinated anti-blocking system, which greatly improves the effect of preventing the screen from being blocked.

[0031] like Figure 4 As shown, the interior of the sieve cover 13 is in a conical structure. The cleaning component 3 is arranged inside the sieve cover 13 and is used to clean the sample adhered to the side walls of the sieve seat 12 and the top wall of the sieve cover 13 during the screening process. The cleaning component 3 includes a second cleaning brush 31. The second cleaning brush 31 is provided with a horizontal end and an inclined end, wherein the horizontal end is flush with the side wall of the sieve seat 12, and the inclined end is flush with the conical shape of the sieve cover 13.

[0032] It should be noted that when the anti-blocking component 2 starts working, the slow rotation of the first cleaning brush 28 will drive the second cleaning brush 31 to rotate as well. Since the horizontal end of the second cleaning brush 31 is flush with the side wall of the sieve seat 12, and the inclined end is flush with the conical shape of the sieve cover 13, the second cleaning brush 31 can always fit closely to the side wall of the sieve seat 12 and the top wall of the sieve cover 13 in the process of following the rotation of the first cleaning brush 28. During rotation, the friction between the bristles and the side wall and the top wall can be used to scrape off the samples adhering to these parts, thereby achieving effective cleaning of the samples on the side wall of the sieve seat 12 and the top wall of the sieve cover 13. Through the coordinated rotation with the first cleaning brush 28, the second cleaning brush 31 can achieve automatic rotation cleaning action without the need for additional power drive.

[0033] like Figure 3 , Figure 4 and Figure 6 As shown, a driving seat 32 is installed and connected to the top of the rotating rod 27, and a threaded seat 29 is rotatably connected to the top of the driving seat 32. The interior of the threaded seat 29 is a hollow structure. A second injection hole 33 in a circular array is opened on the top of the driving seat 32. A second injection pipe 34 is plugged and connected to the top of the sieve cover 13. The second injection pipe 34 is connected to the second injection hole 33, and one end of the second injection pipe 34 is fixedly connected to the output end of the compressed gas machine 222.

[0034] It should be noted that when the compressed gas machine 222 sprays intermittently, the gas is output from its output end into the second spray pipe 34 connected thereto, and then flows into the second spray hole 33 on the top of the drive seat 32 along the connected path. Since the rotating rod 27 will rotate during the screening process to drive the drive seat 32 to rotate, and the threaded seat 29 is hollow to assist gas transmission, the gas can be smoothly sprayed out from the second spray holes 33 at different angles. Through jet cleaning, the sample that falls back onto the sieve near the sieve cover 13 and the sieve seat 12 can be removed in time.

[0035] One end of the second injection hole 33 is in the same direction as the conical shape of the sieve cover 13, so that the ejected gas can better fit the inner surface of the sieve cover 13 and fully purge the attached sample. The gas injection along this shape can ensure that the entire inner surface can be effectively covered, reduce cleaning dead corners, and enhance the coverage range.

[0036] The working principle of the present invention is that the device for testing the performance of cement clinker is used: during the screening process, the dust collecting device can timely absorb fine particles from the screen through the suction holes 111 in a circular array on the base 11 and the suction pipe 112 connected thereto by using negative pressure, thereby preventing fine particles from randomly accumulating in the screen and the device, and maintaining a relatively clean screening environment: After the motor 21 is started, the output end of the motor 21 drives one of the bevel gears 24 to rotate, and the other bevel gear 24 meshing with it rotates accordingly, thereby driving the transmission rod 25 to rotate, and the transmission rod 25 drives the anti-blocking plate 26 to rotate slowly under the sieve seat 12. Under the negative pressure state inside the base 11, the anti-blocking plate 26 can block part of the sieving channel of the sieve when it rotates, redistribute the fine particles that may have blocked the channel, make the sieving of other parts of the sieve more effective, and prevent local excessive blockage. When the anti-blocking plate 26 rotates, it will push the first cleaning brush 28 because it repel each other with the first cleaning brush 28, and use the brush to clean the sample on the sieve in real time to prevent the accumulation of fine particles from clogging the sieve; The motor 21 of the anti-blocking component 2 is started to drive the bevel gear 24 to rotate, and the cam 214 is rotated synchronously through the transmission roller 218 and the driving roller 217. When the cam 214 protrudes and pushes the extrusion wheel 216, the movable plate 215 moves down to compress the spring 219 to store energy. The protrusion rotates, and the spring releases energy to push the movable plate 215 up. The base 11 is driven up and down through the connecting rod to generate vibration, which is transmitted to the screen seat 12 and the screen to reduce blockage. The movement of the base 11 causes the gap between the anti-blocking plate 26 and the screen to change, and the blocked particles are cleared by negative pressure. Start the compressed gas machine 222, and the external air is ejected from the first ejection hole 224 of the anti-blocking plate 26 through the first ejection pipe 223 and the gas hole in the transmission rod 25. As the base 11 moves and the anti-blocking plate 26 rotates, the position of the ejection hole changes, and the air can be ejected to different places of the screen; When the anti-blocking component 2 is started, the first cleaning brush 28 rotates to drive the second cleaning brush 31 to rotate. The second cleaning brush 31 can fit the side wall of the sieve seat 12 and the top wall of the sieve cover 13 due to its structure. When rotating, the friction force of the bristles scrapes the sample and automatically cleans it. The compressed gas machine 222 sprays gas intermittently, and the gas enters the second injection pipe 34 from the output end and then enters the second injection hole 33 of the driving seat 32. The rotating rod 27 rotates to drive the driving seat 32 to rotate, and the gas is ejected from the second injection holes 33 at different angles, and blows the sieve cover 13 and the vicinity of the sieve seat 12 along the cone shape to remove the sample that falls back on the sieve and reduce the impact on the screening.
