Description

Technical Field

[0001] The utility model relates to the field of cement processing equipment, in particular to a raw material ball mill for cement production. Background Art

[0002] Raw materials for cement production, such as raw coal and limestone, need to be ground. A commonly used grinding device is a ball mill, which includes a power-driven cylinder with a certain number of steel balls loaded into the cylinder as grinding bodies. When the cylinder of the ball mill rotates, the grinding bodies are attached to the cylinder lining and carried away by the cylinder due to inertia, centrifugal force, and friction. When they are brought to a certain height, they are thrown down under the action of gravity, thereby crushing the materials in the cylinder. Currently, the patent document with authorization announcement number CN206519209U discloses a ball mill, including a ball mill cylinder for holding the material to be ground, a transmission system connected to the ball mill cylinder for driving the ball mill cylinder to rotate, a liquid supply system arranged on the ball mill cylinder for injecting a liquid medium into the ball mill cylinder, and a constant temperature heating system arranged in the ball mill cylinder for constant temperature heating of the liquid medium injected into the ball mill cylinder. When the ball mill is running, the cylinder rotates at a high speed. When an emergency occurs, the cylinder needs to be stopped as soon as possible. However, the above-mentioned ball mill is not equipped with a braking system. Therefore, when the transmission system stops providing power to the cylinder, the cylinder will continue to rotate for a long time under the action of inertia, which is not conducive to safe production. Utility Model Content

[0003] In view of this, the utility model provides a raw material ball mill for cement production, which can reduce the rotation speed of the ball mill by first using a friction component, and then release the limit of the rack through the second cylinder, so that the torsion spring releases the compressed elastic potential energy, pushes the rack up and moves it closer to the circular gear, so that the rack is stuck in the circular gear, limits and fixes the ball mill, and stops the ball mill from rotating.

[0004] In order to solve the above technical problems, the utility model provides a raw material ball mill for cement production, including a base plate, the base plate is used to connect and support a first support platform and a second support platform, the first support platform and the second support platform are symmetrically arranged on the base plate, the first support platform and the second support platform are used to limit the support of the ball mill, the first support platform and the second support platform are rotatably provided with a ball mill, the ball mill is used to crush cement raw materials, the first support platform is provided with a friction component for decelerating the ball mill, and the second support platform is provided with an emergency stop component for stopping the rotation of the ball mill.

[0005] The friction assembly includes a first cylinder symmetrically arranged on the first support platform. The first cylinder is used to drive the arc-shaped brake pad to move up and down to prevent the arc-shaped brake pad from contacting the brake ring for a long time. The output end of the first cylinder is connected to a arc-shaped brake pad that fits the surface of the ball mill. The arc-shaped brake pad and the brake ring are used in conjunction to slow down the rotation speed of the ball mill.

[0006] Grooves matching the first cylinder are provided at both ends of the first support platform. The grooves are used to place the first cylinder. The first cylinder is fixedly arranged in the grooves. A brake ring used in conjunction with the arc-shaped brake pad is connected to the ball mill. The brake ring is arranged under the arc-shaped brake pad. The arc-shaped brake pad is driven downward by the first cylinder to fit tightly with the brake ring, thereby slowing down the rotation speed of the ball mill.

[0007] The emergency stop assembly includes a circular gear connected to one end of the ball mill, the circular gear is fixed on the ball mill, the circular gear is used to cooperate with the rack, the circular gear is set on one side of the second support platform, and a rack matching the circular gear is provided under the circular gear. The teeth on the rack are clamped in the teeth of the circular gear to limit and fix the ball mill, so that the ball mill stops rotating.

[0008] A boss is provided at one end of the base plate, and a first connecting rod and a second connecting rod are provided between the boss and the second support platform. The first connecting rod and the second connecting rod are fixedly arranged on the boss, and the second connecting rod is arranged at the lower right side of the first connecting rod. The first connecting rod is used to connect the rack and limit the rack so that the rack rotates around the first connecting rod. One end of the rack is rotatably set on the first connecting rod, and the other end of the rack is connected to a limiting hole. The limiting hole is used to limit the rack so that the rack is away from the circular gear when not in use.

[0009] A second cylinder is provided on the other side of the second support platform. The second cylinder is used to control the use of the rack. When an emergency stop is required, the output end of the second cylinder is pulled out of the limiting hole, and the output end of the second cylinder passes through the second support platform and is movably arranged in the limiting hole. When the rack is not in use, the torsion spring is squeezed to insert the output end of the second cylinder into the limiting hole.

[0010] The second connecting rod is provided with a torsion spring for making the rack fit with the circular gear. The torsion spring is located at the angle between the rack and the base plate. The torsion spring is used to release the compressed elastic potential energy of the rack when it is not limited by the second cylinder, so as to push the rack up and move it closer to the circular gear, so that the rack is stuck in the circular gear, limit and fix the ball mill, and stop the ball mill from rotating.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] 1. The output end of the first cylinder drives the arc-shaped brake pad to move downward, so that the arc-shaped brake pad fits the brake ring. The mutual friction between the arc-shaped brake pad and the brake ring reduces the rotation speed of the ball mill.

[0013] 2. Start the second cylinder, retract the output end of the second cylinder and pull it out from the limit hole, so that the rack and the circular gear are fitted together. The second cylinder releases the limit function of the rack, which can reduce direct contact between workers and equipment.

[0014] 3. The torsion spring releases the compressed elastic potential energy, pushing the rack up and moving it closer to the circular gear, so that the rack is stuck in the circular gear, limiting and fixing the ball mill, and stopping the ball mill from rotating.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0021] like Figure 1-4 As shown:

[0022] This embodiment provides a raw material ball mill for cement production, including a base plate 100, which is used to connect and support a first support platform 101 and a second support platform 102. The first support platform 101 and the second support platform 102 are symmetrically arranged on the base plate 100, and the first support platform 101 and the second support platform 102 are used to provide limited support for a ball mill 103. A ball mill 103 is rotatably arranged on the first support platform 101 and the second support platform 102, and the ball mill 103 is used to crush cement raw materials. A friction component 110 for decelerating the ball mill 103 is provided on the first support platform 101, and an emergency stop component 120 for stopping the rotation of the ball mill 103 is provided on the second support platform 102.

[0023] The friction assembly 110 includes a first cylinder 111 symmetrically arranged on the first support platform 101. The first cylinder 111 is used to drive the arc-shaped brake pad 112 to move up and down to prevent the arc-shaped brake pad 112 from being in contact with the brake ring 114 for a long time. The output end of the first cylinder 111 is fixedly connected to a arc-shaped brake pad 112 that fits the surface of the ball mill 103. The arc-shaped brake pad 112 is used in conjunction with the brake ring 114 to slow down the rotation speed of the ball mill 103.

[0024] Grooves 113 matching the first cylinder 111 are provided at both ends of the first support platform 101. The grooves 113 are used to place the first cylinder 111. The first cylinder 111 is fixedly arranged in the grooves 113. A brake ring 114 used in conjunction with the arc-shaped brake pad 112 is connected to the ball mill 103. The brake ring 114 is fixedly arranged on the ball mill 103. The brake ring 114 is arranged below the arc-shaped brake pad 112. The arc-shaped brake pad 112 is pressed down by the first cylinder 111 to fit tightly with the brake ring 114, thereby slowing down the rotation speed of the ball mill 103.

[0025] The emergency stop component 120 includes a circular gear 121 connected to one end of the ball mill 103. The circular gear 121 is fixed on the ball mill 103. The circular gear 121 is used to cooperate with the rack 122. The circular gear 121 is set on one side of the second support platform 102. A rack 122 matching the circular gear 121 is provided below the circular gear 121. The teeth on the rack 122 are clamped in the teeth of the circular gear 121 to limit and fix the ball mill 103, so that the ball mill 103 stops rotating.

[0026] A boss 123 is provided at one end of the base plate 100, and a first connecting rod 124 and a second connecting rod 125 are provided between the boss 123 and the second support platform 102. The first connecting rod 124 and the second connecting rod 125 are fixedly arranged on the boss 123, and the second connecting rod 125 is arranged at the lower right side of the first connecting rod 124. The first connecting rod 124 is used to connect the rack 122 and limit the rack 122 so that the rack 122 rotates around the first connecting rod 124. One end of the rack 122 is rotatably set on the first connecting rod 124, and the other end of the rack 122 is connected with a limiting hole 126. The limiting hole 126 is used to limit the rack 122 so that the rack 122 is away from the circular gear 121 when not in use.

[0027] A second cylinder 128 is provided on the other side of the second support platform 102. The second cylinder 128 is used to control the use of the rack 122. When an emergency stop is required, the output end of the second cylinder 128 is pulled out of the limiting hole 126, and the output end of the second cylinder 128 passes through the second support platform 102 and is movably set in the limiting hole 126. When the rack 122 is not in use, the torsion spring 129 is squeezed to make the output end of the second cylinder 128 inserted into the limiting hole 126.

[0028] A torsion spring 129 is sleeved on the second connecting rod 125 for making the rack 122 fit with the circular gear 121. The torsion spring 129 is located at the angle between the rack 122 and the base plate 100. The torsion spring 129 is used to release the compressed elastic potential energy of the rack 122 when it is not limited by the second cylinder 128, so as to push the rack 122 up and move it closer to the circular gear 121, so that the rack 122 is stuck in the circular gear 121, limit and fix the ball mill 103, and stop the ball mill 103 from rotating.

[0029] Working principle: When the ball mill 103 needs to stop rotating, start the first cylinder 111, and the output end of the first cylinder 111 drives the arc-shaped brake pad 112 to move downward, so that the arc-shaped brake pad 112 fits with the brake ring 114, and the rotation speed of the ball mill 103 is reduced through the mutual friction between the arc-shaped brake pad 112 and the brake ring 114. When the rotation speed of the ball mill 103 decreases, start the second cylinder 128, and the output end of the second cylinder 128 is retracted and pulled out from the limiting hole 126. The torsion spring 129 releases the compressed elastic potential energy, and pushes the rack 122 up to move closer to the circular gear 121, so that the rack 122 is stuck in the circular gear 121, and the ball mill 103 is limited and fixed, so that the ball mill 103 stops rotating.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
