Crushing apparatus for calcium oxide raw material

Abstract

This utility model discloses a crushing device for calcium oxide raw materials, including a base plate. By starting a first motor, the output of the first motor drives a drive rod to rotate. The rotation of the drive rod drives a drive gear to rotate, which in turn drives a driven gear. This solves the problem of the original equipment, which used conveyor blades to initially crush calcium oxide during transport by squeezing against the conveyor pipe wall. However, when the volume of the input calcium oxide solid was large, it would get stuck at the connection between the feeding bin and the conveyor pipe, preventing proper initial crushing. Furthermore, the cleaning and crushing processes within the crushing chamber were driven by two motors. During normal use, the simultaneous operation of both motors resulted in resource waste because the cleaning and crushing processes could not be synchronized, leading to collisions inside the crushing chamber and damage, thus reducing the efficiency of the crushing operation.

Description

Technical Field

[0001] This utility model relates to the field of raw material crushing technology, specifically to a crushing device for calcium oxide raw materials. Background Technology

[0002] Calcium oxide, commonly known as quicklime, is hygroscopic. In the production process of calcium oxide, large pieces of raw material need to be crushed into smaller pieces before being calcined in a furnace. Currently, the crushing equipment crushes calcium oxide raw materials into varying sizes, resulting in incomplete crushing. Furthermore, because calcium oxide powder is corrosive, it can easily cause injury to operators in the production workshop.

[0003] A search revealed patent publication number CN218924809U, which discloses a crushing device for calcium oxide processing raw materials, relating to the field of calcium oxide processing raw material crushing technology. This crushing device aims to solve the technical problem of difficulty in thoroughly and efficiently crushing calcium oxide during processing while ensuring worker safety. The device includes a crushing box with a feeding assembly fixedly connected to its upper end. A first motor is installed at the front end of the crushing box, and a crushing roller is installed at the rear end of the motor's output shaft. The lower end of the crushing box has equidistantly distributed filter through holes. The device utilizes the feeding assembly at the upper end of the crushing box to initially crush large pieces of calcium oxide processing raw materials. A crushing roller and a cleaning brush are installed inside the crushing box. The rapidly rotating crushing roller quickly breaks up the calcium oxide processing raw materials, while the cleaning brush cleans the raw materials adhering to the inner wall and the filter holes. By operating the crushing process in a sealed environment, worker safety is improved.

[0004] The existing technical solutions mentioned above have the following drawbacks: The original equipment initially crushes calcium oxide by squeezing the conveyor blades against the conveyor pipe wall during transportation. However, when the volume of the calcium oxide solid is large, it will get stuck at the connection between the feeding bin and the conveyor pipe, preventing the initial crushing of calcium oxide from proceeding normally. In addition, the cleaning and crushing modes in the crushing box are driven by dual motors. During normal use, the simultaneous operation of the two motors results in a waste of resources because the cleaning and crushing modes cannot be synchronized. This can lead to collisions inside the crushing box, causing damage to the crushing box and reducing the efficiency of the crushing operation. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a crushing device for calcium oxide raw materials, which has the advantage of high-efficiency crushing. It solves the problem that the original equipment used conveyor blades to initially crush calcium oxide during transport by squeezing against the conveying pipe wall. However, when the volume of the input calcium oxide solid was large, it would get stuck at the connection between the feeding bin and the conveying pipe, preventing the initial crushing of calcium oxide from proceeding normally. Furthermore, the cleaning and crushing modes within the crushing chamber were driven by dual motors. During normal use, the simultaneous operation of both motors resulted in resource waste because the cleaning and crushing modes could not be synchronized, leading to collisions inside the crushing chamber and damage, thus reducing the efficiency of the crushing operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for calcium oxide raw materials, comprising a base plate, a receiving box fixedly connected to the left side of the top of the base plate, a receiving container slidably connected to the bottom left side of the receiving box, a crushing chamber connected to the top of the receiving box, a support box connected to the top of the crushing chamber, support plates fixedly connected to the front and rear sides of the top of the base plate, a spiral chamber fixedly connected inside the support plates, the bottom left side of the spiral chamber connected to the top of the support box, a support column fixedly connected to the right side of the top of the base plate, a first motor fixedly connected to the top of the support column, a working groove opened on the top surface of the support column, a second motor fixedly connected to the bottom of the working groove, a double-roll crushing chamber connected to the top of the spiral chamber, a feeding bin connected to the top of the double-roll crushing chamber, a crushing component arranged on the right side of the bottom of the base plate, and a crushing component arranged inside the crushing chamber.

[0007] In a preferred embodiment of this invention, the crushing assembly includes an active transmission rod, which is fixedly connected to the output end of a first motor. The active transmission rod passes through the right side of the double-roll crushing chamber. A drive gear is fixedly connected to the right side of the surface of the active transmission rod. A driven gear meshes with the rear side of the drive gear. A driven transmission rod is fixedly connected to the surface of the driven gear. The left side of the driven transmission rod passes through the right side of the double-roll crushing chamber. Toothed rollers are fixedly connected to the left sides of both the active and driven transmission rods. A spiral fan blade is fixedly connected to the output end of the second motor. The left side of the spiral fan blade extends to the left side of the spiral chamber.

[0008] In a preferred embodiment of this invention, the crushing assembly includes a drive shaft that is slidably connected inside the crushing chamber. The front side of the drive shaft passes through the front side of the crushing chamber and is fixedly connected to a third motor. Crushing plates are fixedly connected to the surface of the drive shaft, and the number of crushing plates is five. A feeding hole is provided at the bottom of the crushing chamber, and the number of feeding holes is several.

[0009] In a preferred embodiment of this invention, a cleaning plate is fixedly connected to the surface of the drive shaft, and a brush head is fixedly connected to the outer side of the cleaning plate. The number of brush heads is several, and the cleaning plate is located at the interval between the pulverizing plates.

[0010] As a preferred embodiment of this utility model, a sliding groove is provided at the bottom of the left side of the receiving box, and the receiving box is slidably connected to the inside of the sliding groove via a slide rail. A handle is fixedly connected to the left side of the receiving box, and the handle is used in conjunction with the sliding groove.

[0011] As a preferred embodiment of this utility model, a glass observation window is provided on the top left side of the receiving box, and the glass observation window is used in conjunction with the crushing component.

[0012] As a preferred embodiment of this utility model, the bottom of the base plate is fixedly connected with four self-locking casters.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the arrangement of crushing and grinding components, starts the first motor. The output of the first motor drives the active transmission rod to rotate, which in turn drives the active gear to rotate. The active gear, in turn, drives the driven gear to rotate, which in turn drives the driven transmission rod to rotate. The rotation of the active and driven transmission rods drives the toothed roller to rotate, thus initially crushing the input calcium oxide raw material. The material is then fed into a connected spiral chamber after initial crushing in the double-roller crushing chamber. The second motor is then started, and its output drives the spiral fan blades to rotate. As the spiral fan blades rotate, they transport the initially crushed calcium oxide into the grinding chamber. During this transport process, the calcium oxide undergoes further fine crushing due to the compression between the spiral fan blades and the spiral chamber wall. Finally, the third motor is started, and its output drives the transmission shaft to rotate. When the rotating shaft rotates, it drives the crushing plate and cleaning plate to rotate as well. The crushing plate crushes the calcium oxide that has been finely crushed before entering the crushing chamber, while the cleaning plate cleans the walls of the crushing chamber to prevent the crushed calcium oxide from adhering to them. This solves the problem of the original equipment, which used the conveyor blades to squeeze the calcium oxide against the conveying pipe wall during transport. However, when the volume of the calcium oxide solid was large, it would get stuck at the connection between the feeding chamber and the conveying pipe, preventing the initial crushing of the calcium oxide from proceeding normally. In addition, the cleaning and crushing modes in the crushing chamber are driven by two motors. During normal use, when the two motors work simultaneously, it wastes resources because the cleaning and crushing modes cannot be synchronized. This can lead to collisions inside the crushing chamber, causing damage and reducing the efficiency of the crushing operation.

[0015] 2. By setting up the crushing component, this utility model can crush calcium oxide of different volumes fed into the raw material silo, avoiding the situation where large calcium oxide gets stuck at the connection between the feeding silo and the conveying pipe, which would prevent the calcium oxide crushing operation from being normal.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3As shown, the present invention provides a crushing device for calcium oxide raw materials, including a base plate 1. A receiving box 2 is fixedly connected to the left side of the top of the base plate 1. A receiving container 3 is slidably connected to the bottom left side of the receiving box 2. A crushing chamber 4 is connected to the top of the receiving box 2. A support box 5 is connected to the top of the crushing chamber 4. Support plates 6 are fixedly connected to the front and rear sides of the top of the base plate 1. A spiral chamber 7 is fixedly connected inside the support plate 6. The bottom left side of the spiral chamber 7 is connected to the top of the support box 5. A support column 8 is fixedly connected to the right side of the top of the base plate 1. A first motor 9 is fixedly connected to the top of the support column 8. A working groove 10 is opened on the top surface of the support column 8. A second motor 11 is fixedly connected to the bottom of the working groove 10. A double roller crushing chamber 12 is connected to the top of the spiral chamber 7. A feeding chamber 13 is connected to the top of the double roller crushing chamber 12. A crushing component 14 is arranged on the right side of the bottom of the base plate 1. A crushing component 15 is arranged inside the crushing chamber 4.

[0022] refer to Figure 2 The crushing assembly 14 includes an active drive rod 141, which is fixedly connected to the output end of the first motor 9. The active drive rod 141 passes through the right side of the double-roll crushing chamber 12. An active gear 142 is fixedly connected to the right side of the surface of the active drive rod 141. A driven gear 143 meshes with the rear side of the active gear 142. A driven drive rod 144 is fixedly connected to the surface of the driven gear 143. The left side of the driven drive rod 144 passes through the right side of the double-roll crushing chamber 12. Wolf tooth rollers 145 are fixedly connected to the left sides of the surfaces of both the active drive rod 141 and the driven drive rod 144. A spiral fan blade 146 is fixedly connected to the output end of the second motor 11. The left side of the spiral fan blade 146 extends to the left side of the spiral chamber 7.

[0023] As a technical optimization of this utility model, by setting the crushing component 14, the calcium oxide of different volumes fed into the raw material bin can be crushed, avoiding the large calcium oxide from getting stuck at the connection between the feeding bin 13 and the conveying pipe, which would prevent the calcium oxide crushing operation from being normal.

[0024] refer to Figure 3 The crushing assembly 15 includes a drive shaft 151, which is slidably connected inside the crushing chamber 4. The front side of the drive shaft 151 passes through the front side of the crushing chamber 4 and is fixedly connected to a third motor 152. Crushing plates 153 are fixedly connected to the surface of the drive shaft 151. There are five crushing plates 153. The bottom of the crushing chamber 4 is provided with a feeding hole 154. There are several feeding holes 154.

[0025] As a technical optimization of this utility model, by setting the crushing component 15, the calcium oxide after the crushing operation can be crushed more finely, avoiding the situation where the calcium oxide after the crushing operation is too large and affects subsequent production.

[0026] refer to Figure 3 A cleaning plate 16 is fixedly connected to the surface of the drive shaft 151, and a brush head 17 is fixedly connected to the outer side of the cleaning plate 16. There are several brush heads 17, and the cleaning plate 16 is located at the interval between the crushing plates 153.

[0027] As a technical optimization of this utility model, by setting the cleaning plate 16, the wall of the crushing chamber 4 can be cleaned simultaneously during the crushing operation in the crushing chamber 4, so as to avoid the situation where the crushed calcium oxide adheres to the wall of the crushing chamber 4 and affects the normal operation of the crushing operation.

[0028] refer to Figure 3 The bottom left side of the receiving box 2 is provided with a sliding groove 18. The receiving box 2 is slidably connected to the inside of the sliding groove 18 via a slide rail. A handle 19 is fixedly connected to the left side of the receiving box 2. The handle 19 is used in conjunction with the sliding groove 18.

[0029] As a technical optimization of this utility model, by setting the chute 18, the material receiving box 3 can be taken out more conveniently by cooperating with the handle 19 and the slide rail, so as to avoid the excessive amount of crushed calcium oxide in the material receiving box 3 during the crushing operation, which would affect the normal operation of the crushing chamber 4.

[0030] refer to Figure 3 A glass observation window 20 is provided on the top left side of the receiving box 3. The glass observation window 20 is used in conjunction with the crushing component 15.

[0031] As a technical optimization of this utility model, by setting the glass observation window 20, the amount of crushed calcium oxide in the receiving box 3 can be observed more conveniently through the glass observation window 20, so as to avoid the receiving box 3 collecting too much crushed calcium oxide during the crushing operation, which would affect the normal operation of the crushing chamber 4.

[0032] refer to Figure 1 The bottom of the base plate 1 is fixedly connected with four self-locking casters 21.

[0033] As a technical optimization of this utility model, the self-locking caster wheel 21 can fix the base plate 1 when it moves to the working area where the crushing operation is required, so as to avoid the interruption of the crushing operation due to the position displacement of the base plate 1 during the crushing operation.

[0034] The working principle and usage process of this utility model are as follows: In use, the user first feeds calcium oxide raw material into the feeding hopper 13, starts the first motor 9, and the output of the first motor 9 drives the active transmission rod 141 to rotate. The rotation of the active transmission rod 141 drives the active gear 142 to rotate, which in turn drives the driven gear 143 to rotate. The driven gear 143 then drives the driven transmission rod 144 to rotate. The rotation of the active and driven transmission rods 141 and 144 simultaneously drives the toothed roller 145 to rotate, thus initially crushing the fed calcium oxide raw material. The crushed material then enters the connected spiral chamber 7 after initial crushing in the double-roller crushing chamber 12. The second motor 11 is then started, and its output drives the spiral fan blades 146 to rotate. When the fan blade 146 rotates, it carries the initially crushed calcium oxide into the crushing chamber 4. During the conveying process, the calcium oxide is finely crushed by the squeezing of the spiral fan blade 146 and the wall of the spiral chamber 7. The third motor 152 is started, and the output end of the third motor 152 drives the transmission shaft 151 to start rotating. When the transmission shaft 151 rotates, it drives the crushing plate 153 and the cleaning plate 16 to start rotating. When the crushing plate 153 rotates, it crushes the calcium oxide that has been finely crushed in the crushing chamber 4. When the cleaning plate 16 rotates, it cleans the wall of the crushing chamber 4 to prevent the crushed calcium oxide from adhering to the wall of the crushing chamber 4. The calcium oxide that has been crushed in the crushing chamber 4 enters the inside of the receiving box 3 through the bottom feeding hole 154, achieving a high-efficiency crushing effect.

[0035] In summary: This calcium oxide raw material crushing equipment comprises: a base plate 1, a receiving box 2, a receiving hopper 3, a crushing chamber 4, a support box 5, a support plate 6, a spiral chamber 7, a support column 8, a first motor 9, a working trough 10, a second motor 11, a double-roll crushing chamber 12, a feeding chamber 13, a crushing assembly 14, a drive transmission rod 141, a drive gear 142, a driven gear 143, a driven transmission rod 144, a toothed roller 145, a spiral fan blade 146, a crushing assembly 15, a transmission shaft 151, a third motor 152, a crushing plate 153, a conveying hole 154, a cleaning plate 16, a brush head 17, a chute 18, a handle 19, and a glass observation window 20. The use of the self-locking caster wheel 21 solves the problem of the original equipment's initial crushing of calcium oxide by the compression of the conveying pipe wall by the transport blades during transportation. However, when the volume of the calcium oxide solid input is large, it will get stuck at the connection between the feeding bin and the conveying pipe, which will prevent the initial crushing of calcium oxide from proceeding normally. In addition, the cleaning mode and the crushing mode in the crushing box are driven by dual motors. During normal use, the two motors work at the same time, which causes waste of resources. Because the cleaning mode and the crushing mode cannot be synchronized, collisions occur inside the crushing box, which can damage the crushing box and reduce the efficiency of the crushing operation.
