Description

Technical Field

[0001] This invention relates to the field of dry mortar equipment technology, and in particular to a dry mortar preparation anti-segregation device and its usage method. Background Technology

[0002] Dry-mixed mortar is a mixture of loose powder and granular materials. Depending on the specific requirements of construction, it is prepared in different specifications based on particle size and proportion. After mixing, due to their different properties, secondary separation of powder and granular materials can occur during storage, transportation, and use. This phenomenon is known as "segregation" in dry-mixed mortar. The main cause of dry-mixed mortar segregation is the accumulation of materials into a cone shape. Because the angle of repose of powder and granular materials is different, the dry-mixed mortar naturally forms a cone shape during accumulation. The powder naturally rises with the cone, while granular materials such as sand and gravel naturally slide down from the edges, ultimately leading to segregation. If segregation is not effectively controlled during the preparation and storage of dry-mixed mortar, it will seriously affect the quality of the finished product and the quality of construction.

[0003] For example, CN106079099B discloses a dry mortar anti-segregation device, including a conveying component, a storage tank, and an anti-segregation component. This invention can effectively prevent mortar segregation by setting a three-level anti-segregation structure on the anti-segregation component and cooperating with the anti-segregation support.

[0004] Based on the above scheme, the anti-segregation support can help to distribute the mortar evenly at the bottom of the storage tank. However, the anti-segregation support can easily cause the dry mortar to accumulate in a cone shape in the storage tank. This causes large particles in the dry mortar to roll from the top to the bottom and gather at the outer edge of the mortar pile, resulting in segregation. Furthermore, due to the different specifications of dry mortar, the existing dry mortar anti-segregation device is not convenient to adjust the discharge rate in a timely manner according to the different specifications of dry mortar, which affects the anti-segregation effect during the preparation of dry mortar.

[0005] Therefore, it is necessary to solve the above problems by developing a dry mortar preparation anti-segregation device and its usage method. Summary of the Invention

The end of the discharge pipe away from the auger conveyor is located inside the feed hopper, and the opening of the discharge pipe faces downward.

[0018] A method for using a dry powder mortar preparation anti-segregation device, the specific steps of which are as follows:

[0019] S1. First, the dry mortar material is transported to the conveying hopper on the diversion buffer component through the feeding component.

[0020] S2. Secondly, the dry mortar material in the conveying hopper is diverted by the three diversion pipes in the diversion buffer assembly, and the segregation of the dry mortar material during the falling process is reduced by the conveying pipe.

[0021] S3. Finally, adjust the discharge rate of dry mortar by adjusting the discharge component, and discharge the dry mortar in the diversion buffer component to the collection component.

[0022] S4. Finally, by controlling the material collection component, the material collection component is made to collect materials evenly during the process of adjusting the cooperation between the discharge component and the material collection component.

[0023] The technical effects and advantages of this invention are as follows:

[0024] 1. This invention uses three diversion pipes to divert dry mortar material in the conveying hopper, preventing the large flow of dry mortar material from affecting the buffering effect of the diversion buffer component during its descent. This diversion reduces segregation of the dry mortar material. By using a buffer baffle, rubber pad, and electromagnetic spring working together, when the dry mortar material collides with the buffer baffle inside the conveying pipe, the electromagnetic spring is compressed, the buffer baffle deflects at a certain angle in the direction of compression, and the rubber pad provides cushioning. This buffers the dry mortar material in the conveying pipe, reducing its descent speed and thus decreasing the speed difference between powdery and granular materials, thereby preventing segregation during descent.

[0025] 2. This invention, by setting a fixed screen, allows dry mortar material to be evenly discharged through multiple outlets, expanding the discharge area. This disperses the dry mortar material as it falls through the fixed screen, preventing it from forming a conical accumulation and thus preventing segregation. The discharge rate in the regulating discharge component is adjusted based on the specifications and falling speed of the dry mortar material in the diversion buffer assembly. A second motor drives a gear to rotate clockwise, causing the outer gear ring to rotate counterclockwise. The regulating screen rotates along with the outer gear ring, causing the discharge port on the regulating screen to misalign with the discharge port on the fixed screen, changing the overlap area between the discharge port and the discharge port. This adjusts the discharge rate of the regulating discharge component. Through the cooperation between the diversion buffer assembly and the regulating discharge component, segregation of the dry mortar material during transportation is prevented.

[0026] 3. This invention adjusts the material discharge component and the material collection component to work together. The output shaft of the third motor drives the turntable and the storage tank to rotate together. Then, the scraper paddle quickly and evenly scrapes the dry mortar material in the storage tank, avoiding the formation of a cone-shaped accumulation of dry mortar material in the storage tank and causing segregation. Then, the controller controls the hydraulic lifting column to drive the support base, turntable and storage tank to descend at a uniform speed, so that the dry mortar material evenly fills the storage tank.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] First embodiment: as follows Figure 1-10As shown, a dry powder mortar preparation anti-segregation device of the present invention includes a feeding component 1, a diversion buffer component 2, an adjusting discharge component 3, and a collecting component 4. There are three adjusting discharge components 3, and all three adjusting discharge components 3 are located below the diversion buffer component 2. The diversion buffer component 2 and the adjusting discharge component 3 are located above the collecting component 4. The feeding component 1 is located on one side of the diversion buffer component 2.

[0040] In use, the dry mortar material is transported to the diversion and buffer component 2 through the feeding component 1. The diversion and buffer component 2 buffers the dry mortar material to prevent segregation during the falling process. Then, the discharge volume of the regulating discharge component 3 is adjusted in a timely manner according to the specifications of the dry mortar material and the falling speed. The diversion and buffer component 2 and the regulating discharge component 3 work together to prevent segregation of the dry mortar material during transportation. Then, the regulating discharge component 3 and the collecting component 4 work together to make the dry mortar material evenly fill the storage tank 406.

[0041] like Figure 2 As shown, the feeding assembly 1 includes a mounting frame 101. An auger conveyor 102 is fixedly mounted on the top of the mounting frame 101. A first motor 103 is fixedly mounted on one end of the auger conveyor 102. A feed hopper 104 is fixedly mounted on the surface of the auger conveyor 102. A discharge pipe 105 is fixedly mounted on the end of the auger conveyor 102 away from the feed hopper 104. The feed hopper 104 and the discharge pipe 105 are respectively fixedly mounted on both sides of the auger conveyor 102. The feed hopper 104 is configured as a funnel structure that is larger at the top and smaller at the bottom. The end of the discharge pipe 105 away from the auger conveyor 102 is located inside the feeding hopper 201, and the opening of the discharge pipe 105 faces downward.

[0042] In use, by turning on the first motor 103, the spiral blades inside the auger conveyor 102 rotate and transport the dry mortar material inside the feed hopper 104 to the discharge pipe 105. Due to the spiral shape of the spiral blades, the dry mortar material is squeezed and stirred during the conveying process, which avoids the phenomenon of segregation of the dry mortar material during the feeding process. Then, the dry mortar material is discharged into the conveying hopper 201 on the diversion buffer assembly 2 through the discharge pipe 105.

[0043] like Figure 4 , Figure 5 , Figure 6As shown, the diversion buffer assembly 2 includes a conveying hopper 201. Three diversion pipes 202 are fixedly installed at the lower end of the conveying hopper 201. A conveying pipe 203 is fixedly installed at the lower end of the three diversion pipes 202. A buffer seat 204 is fixedly installed inside the conveying pipe 203. A buffer baffle 205 is movably hinged to the surface of the buffer seat 204. A rubber pad 206 is fixedly installed on the surface of the buffer baffle 205. Multiple buffer seats 204 are provided, and adjacent buffer seats 204 are staggered inside the conveying pipe 203. A buffer frame 207 is fixedly installed at the lower end of the buffer seat 204. An electromagnetic spring 208 is fixedly installed on the surface of the buffer frame 207. Multiple electromagnetic springs 208 are provided, and multiple electromagnetic springs 208 are fixedly installed between the buffer frame 207 and the buffer baffle 205.

[0044] In use, the dry mortar material in the hopper 201 is diverted into the conveying pipe 203 through three diversion pipes 202. Because the powder and granular materials in the dry mortar have different properties, their falling speeds are also different. Therefore, segregation is prone to occur during the descent of the dry mortar material into the conveying pipe 203. A buffer baffle 205 is installed to buffer the dry mortar material, reducing its falling speed and the speed difference between the powder and granular materials, thus mitigating segregation. When the dry mortar material collides with the buffer baffle 205, the rubber pad 206 provides some cushioning. Then, due to the gravity of the dry mortar material, the electromagnetic spring 208 is compressed, and the buffer baffle 205 deflects at a certain angle in the direction of compression of the electromagnetic spring 208, thereby reducing the impact force when the dry mortar material collides with the buffer baffle 205. The projectile height of the dry mortar material is reduced to prevent the separation of powdery and granular materials due to the high ejection height, thereby reducing segregation during the descent. Three diversion pipes 202 are installed to divert the dry mortar material in the conveying hopper 201, preventing the large discharge volume from affecting the buffering effect of the diversion buffer component 2 during descent. This also prepares for the uniform collection of the subsequent collection component 4. The diversion design mitigates segregation by using buffer baffles 205, rubber pads 206, and electromagnetic springs 208 in conjunction to buffer the dry mortar material within the conveying pipe 203, reducing its descent speed and thus minimizing the speed difference between powdery and granular materials, thereby preventing segregation during descent.

[0045] like Figure 7 , Figure 8 , Figure 9As shown, the adjustable discharge assembly 3 includes a discharge bin 301. A fixed screen plate 302 is fixedly installed at the bottom of the discharge bin 301. A fixed frame 303 is fixedly installed on the surface of the discharge bin 301. An external gear ring 304 is movably installed on the surface of the fixed frame 303. A gear 305 is movably installed at one end of the external gear ring 304. A second motor 306 is fixedly installed on the surface of the gear 305. An adjustable screen plate 307 is fixedly installed on the inner wall of the external gear ring 304. The surface of the fixed screen plate 302 has multiple discharge ports, which are arranged in a ring on the surface of the fixed screen plate 302. The adjustable screen plate 307 is movably installed below the fixed screen plate 302. The surface of the adjustable screen plate 307 has multiple discharge ports, and the size of the discharge ports is equal to the size of the discharge ports.

[0046] During use, dry mortar materials tend to accumulate into a cone shape during discharge. Since powder and granular materials have different angles of repose, during this accumulation process, the powder naturally rises with the cone, while granular materials such as sand and gravel naturally slide down from the edges, ultimately leading to separation of the powder and granular materials. Therefore, by setting an adjusting discharge component 3 to regulate the dry mortar material in the diversion buffer component 2, segregation caused by the cone-shaped accumulation of dry mortar material is avoided. When the dry mortar material is transported to the discharge hopper 301 through the conveying pipe 203, a fixed screen 302 is set to ensure uniform discharge through multiple discharge ports, expanding the discharge area. This allows the dry mortar material to be dispersed through the fixed screen 302, preventing it from falling straight down and forming a cone-shaped accumulation, thus playing a certain role in preventing segregation.

[0047] In actual use, by turning on the second motor 306, the second motor 306 drives the gear 305 to rotate clockwise. The rotation of the gear 305 causes the outer gear ring 304 to rotate counterclockwise. Then, the adjusting screen 307 rotates together with the outer gear ring 304, thereby causing the discharge port on the adjusting screen 307 to be misaligned with the discharge port on the fixed screen 302. By changing the overlapping area of ​​the discharge port and the discharge port, the discharge volume is changed. By adjusting the screen 307 and the fixed screen 302 in coordination, the discharge volume is adjusted according to the amount of dry mortar material being fed. A lower degree of overlap results in a smaller discharge volume.

[0048] like Figure 10As shown, the material collection assembly 4 includes a base 401, a hydraulic lifting column 402 fixedly mounted on the surface of the base 401, a support base 403 fixedly mounted on the upper end of the hydraulic lifting column 402, a third motor 404 fixedly mounted on the surface of the support base 403, and a turntable 405 rotatably connected to the output shaft of the third motor 404 via bearings. A storage bin 406 is movably mounted above the turntable 405. Three pressure weighing sensors 407 are fixedly mounted inside the base 401. 07 are respectively set on the base 401. The controller 408 is fixedly set on the surface of the base 401, and the pressure weighing sensor 407 is electrically connected to the controller 408. A rotating groove is opened at the position where the output shaft of the third motor 404 is connected to the support base 403. The output shaft of the third motor 404 moves through the support base 403 and extends into the interior of the turntable 405. An annular limiting groove is provided at the position where the support base 403 is connected to the turntable 405. A placement groove is provided on the surface of the turntable 405, and the storage bucket 406 is placed inside the placement groove.

[0049] like Figure 7 As shown, a connecting rod 308 is fixedly installed at the lower end of the adjusting screen 307, and the connecting rod 308 is located at the center of the adjusting screen 307. A scraper paddle 309 is fixedly installed at one end of the connecting rod 308. Three scraper blades are installed inside the scraper paddle 309, and the three scraper blades are arranged in a ring on the surface of the connecting rod 308.

[0050] When dry mortar material is discharged into the storage hopper 406 through the adjusting discharge component 3, the adjusting discharge component 3 and the collecting component 4 work together to ensure that the dry mortar material evenly fills the storage hopper 406. During use, the third motor 404 is turned on, causing its output shaft to drive the turntable 405 to rotate. The storage hopper 406, placed on the turntable 405, rotates along with it. Then, the scraper paddle 309 quickly and evenly scrapes the dry mortar material in the storage hopper 406, preventing the dry mortar material from accumulating in the storage hopper. The conical accumulation in the bucket 406 leads to segregation, which also reduces the gaps between the dry mortar materials during accumulation. Then, the controller 408 controls the hydraulic lifting column 402 to drive the support base 403, turntable 405 and storage bucket 406 to descend at a uniform speed, so that the adjusting discharge component 3 maintains a certain distance from the dry mortar materials in the storage bucket 406, and avoids the adjusting discharge component 3 from being buried in the dry mortar materials, thereby affecting the smoothness of the discharge of the adjusting discharge component 3.

[0051] It is worth noting that when the material passes through the diversion buffer component 2, the falling material can generate an impact force on the buffer baffle 205, thus causing the electromagnetic spring 208 to compress. In this way, the electromagnetic spring 208 can achieve a buffering effect on the material during feeding by its own compression, preventing the material from being fed too quickly and causing segregation. At the same time, the electromagnetic spring 208 uses the amount of compression to detect the weight of the falling material in real time, which can effectively detect the state of the falling material. The tilt angle of the buffer baffle 205 is closely related to the feeding speed of the material. Therefore, the dynamic change of the buffer baffle 205 can effectively adjust the feeding speed of the material. The feeding speed of the material also directly affects the discharge speed of the discharge component 3. In this way, the discharge volume of the discharge component 3 can be adjusted in real time according to the amount of material fed, achieving a one-to-one correspondence between feeding and discharge. This not only prevents material accumulation but also plays a role in diverting and preventing segregation of the material.

[0052] It is worth noting that among the several sets of electromagnetic springs 208 installed in the diversion buffer assembly 2, the top two sets of electromagnetic springs 208 serve to buffer the material initially introduced and detect the material quantity. The middle sets of electromagnetic springs 208 adjust the tilt angle of the buffer baffle 205 when the above two sets of electromagnetic springs 208 detect a significant change in the material quantity. The bottom two sets of electromagnetic springs 208 are used to calibrate the material feeding speed that is finally introduced into the regulating discharge assembly 3 after the middle electromagnetic springs 208 adjust the material feeding speed. This allows for the verification of the effectiveness of the material buffering and anti-segregation of the diversion buffer assembly 2.

[0053] In actual use, the feeding component 1 conveys materials via the auger conveyor 102. This means that the material cannot always be conveyed in a fixed quantity. Consequently, material may accumulate and suddenly increase, or become discontinuous and decrease. The increased material volume accelerates the falling speed, increasing the possibility of segregation during feeding. Conversely, when the material decreases, the lack of restraint on large particles causes them to fall faster than small powder particles, exacerbating segregation. Therefore, each situation must be analyzed individually.

[0054] When the compression of the top two sets of electromagnetic springs 208 increases, it indicates that the amount of material introduced into the diversion buffer assembly 2 from the feeding component 1 has increased. This causes the material to fall too quickly, and the impact force on the middle sets of electromagnetic springs 208 during the fall will increase, leading to an increase in the compression of the middle sets of electromagnetic springs 208. At this time, the controller 408 controls the current introduced into the middle sets of electromagnetic springs 208 to increase the elastic coefficient of the electromagnetic springs 208. This increases the supporting force of the electromagnetic springs 208 on the buffer baffle 205, reducing the impact of the material on the buffer baffle 205. The angle of deflection after compression slows down the falling speed of the material. After the feeding speed is adjusted by the middle set of electromagnetic springs 208, the material falls along the buffer baffle 205. The compression of the two bottom electromagnetic springs 208 under the pressure of the material can be used to directly measure the falling speed of the material. If the compression of the bottom electromagnetic springs 208 is still greater than before, the controller 408 continues to increase the current of the middle set of electromagnetic springs 208, thereby continuously improving the blocking and buffering effect of the middle buffer baffle 205 on the material, until the compression of the bottom electromagnetic springs 208 returns to normal.

[0055] When the elastic coefficient of the middle electromagnetic spring 208 increases to the first threshold, but the compression of the bottom electromagnetic spring 208 is still increasing, it indicates that the material introduced into the diversion buffer assembly 2 from the feeding assembly 1 is large and has exceeded the buffering capacity of the diversion buffer assembly 2. At this time, the controller 408 controls the speed of the first motor 103 in the feeding assembly 1 to reduce the material conveying amount, and at the same time controls the current value of all electromagnetic springs 208 except the bottom one to reach the maximum. In this way, the ultimate buffering and diversion of the material can be achieved through multiple sets of electromagnetic springs 208, and emergency measures can be taken when the material is discharged. The bottom electromagnetic spring 208 still detects the material discharge amount based on its own compression amount, which serves as the control signal of the device when the material is discharged.

[0056] It is worth noting that when the lowest electromagnetic spring 208 detects an increase in compression, the material is introduced from the diversion buffer assembly 2 into the regulating discharge assembly 3. At this time, the controller 408 controls the number of rotations of the second motor 306 based on the change in compression of the lowest electromagnetic spring 208. This, in turn, drives the regulating screen 307 to rotate by a corresponding angle through the meshing of the gear 305 and the external gear ring 304. This allows the discharge port on the regulating screen 307 to be misaligned with the discharge port on the fixed screen 302. The amount of misalignment is determined by the change in compression of the lowest electromagnetic spring 208. By increasing the overlapping area of ​​the discharge port and the discharge port, the increase in the weight of the material during discharge is matched, preventing material accumulation and segregation.

[0057] Conversely, when the compression of the top two sets of electromagnetic springs 208 decreases, it indicates that the amount of material introduced into the diversion buffer assembly 2 by the feeding assembly 1 is less. As a result, the force exerted on the buffer baffle 205 when the material falls decreases, and the deflection angle of the buffer baffle 205 is larger. This causes the rolling tilt angle of the material on the buffer baffle 205 to decrease, which leads to larger particles falling first before smaller particles. This results in uneven material falling and segregation. Therefore, the controller 408 controls the first motor 103 in the feeding assembly 1 to increase its speed, thereby increasing the amount of material introduced into the diversion buffer assembly 2 per unit. By increasing the amount of material, segregation during material falling is avoided. Increasing the amount of material restricts the degree of freedom between large particles during material falling, thus limiting large particles and preventing segregation.

[0058] This allows the electromagnetic spring 208 to be adjusted in real time to buffer the material according to the amount of material introduced into the diversion buffer component 2 from the feeding component 1, ensuring that the material speed introduced from the bottom of the diversion buffer component 2 into the regulating discharge component 3 is always within the standard speed range, which can greatly reduce segregation. Through the cooperation between the diversion buffer component 2 and the regulating discharge component 3, the segregation of dry mortar materials during transportation can be effectively avoided.

[0059] It is worth noting that during the material collection process, when the discharge port of the discharge component 3 is increased, the amount of material in the storage tank 406 increases. Therefore, the amount of material in the storage tank 406 is detected by the pressure weighing sensor 407. Based on this, the controller 408 adjusts the speed of the third motor 404 in real time according to the weight change of the pressure weighing sensor 407 to match the change in the amount of material discharged, ensuring that the material is in a uniform state during discharge and improving the anti-segregation effect of the material.

[0060] Second embodiment: The present invention also discloses a method for using a dry powder mortar preparation anti-segregation device, the specific steps of which are as follows:

[0061] S1. First, the dry mortar material is transported to the conveying hopper 201 on the diversion buffer assembly 2 through the feeding component 1.

[0062] S2. Secondly, the dry mortar material in the conveying hopper 201 is diverted by the three diversion pipes 202 in the diversion buffer assembly 2, and the segregation of the dry mortar material during the falling process is reduced by the conveying pipe 203.

[0063] S3. Then, by adjusting the discharge component 3, the discharge amount of dry mortar material is adjusted, and the dry mortar material in the diversion buffer component 2 is discharged into the collection component 4.

[0064] S4. Finally, by controlling the material collection component 4, the material collection component 4 is made to collect materials evenly during the process of adjusting the cooperation between the discharge component 3 and the material collection component 4.
