Description

Technical Field

[0001] The utility model relates to the technical field of limestone grinding and pulping, in particular to a fully automatic mill steel ball adding device and a fully automatic mill steel ball adding system. Background Art

[0002] At present, the main flue gas desulfurization process used in thermal power plants is limestone / gypsum wet desulfurization process, and wet ball mills are often used. The main function of the wet ball mill is to grind limestone into limestone slurry. Steel balls are the main material for grinding limestone in the ball mill. The grinding effect produced by the mutual collision and friction between the steel balls, limestone and the cylinder of the ball mill completes the slurry making of the ball mill. Steel balls are one of the important parts of the ball mill and one of the primary wear materials. Therefore, there are requirements for the amount and size of steel balls added to the ball mill. During the grinding process, the number of steel balls will decrease due to wear, so the ratio of steel balls will change, which is prone to reduce the pulping screening rate and coarseness, affecting the pulping efficiency and increasing power consumption. Too few steel balls will result in insufficient grinding, and the particle fineness will not meet the requirements, which will affect the consumption of limestone slurry in the absorption tower. The substandard slurry will cause slurry deposition at the bottom of the absorption tower. When it accumulates to a certain height, it will block the inlet of the slurry circulation pump, causing the liquid-gas ratio of the system to decrease. In the long run, it will cause incompletely reacted calcium sulfite to adhere to the surface of calcium carbonate, causing sulfite blinding; too many steel balls will increase the load, increase energy consumption, and cause waste of resources.

[0003] In order to ensure that the ratio of steel balls to feed materials in the ball mill meets the requirements, thermal power plants usually rely on the personal experience of the on-site operators of the desulfurization system. When there are fewer steel balls in the ball mill, they will add the steel balls manually. There are many ways to add steel balls manually. Some workers add steel balls to the ball mill by hand or with a shovel. Some use a crane to add balls to the ball mill through a ball adding funnel. Others use a crane to lift the steel balls to the weighing feeder platform on the second floor, and then manually put the steel balls into the ball adding port of the ball mill one by one. Although this method of manually adding steel balls can meet the ball adding needs of the ball mill, it has the following defects and disadvantages:

[0004] (1) It consumes a lot of labor and has a high labor intensity, and there are also risks of human and material safety;

[0005] (2) Due to fluctuations in actual unit load, sulfur content and other operating conditions on site, the daily demand for limestone grinding varies greatly. When the operating conditions change, the manual ball adding method cannot add steel balls according to the ball consumption ratio specified in the process. There is a possibility that the ball consumption ratio required by the process cannot be achieved, which affects the mill pulping efficiency or is lower than the ball consumption ratio, resulting in an imbalance in the steel ball ratio;

[0006] (3) There is no accurate data basis for artificially adding steel balls, and it is impossible to accurately count the current steel ball consumption, resulting in the phenomenon of adding too little or too much;

[0007] (4) It is impossible to add steel balls manually on time, resulting in reduced limestone grinding efficiency or waste of steel balls in the current period;

[0008] (5) Artificial ball addition cannot maintain the steel ball filling rate and the reasonable ratio of steel balls. Utility Model Content

[0031] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0033] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings or are used to describe the relative positional relationships of components in the vertical, perpendicular or gravity direction.

[0034] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection, or an indirect connection; it can be a wired connection, or a wireless connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] Embodiment 1

[0037] The first embodiment of the utility model provides a fully automatic grinding mill steel ball adding device, which may include a ball storage bin, a ball feeding mechanism, a blocking sensor, a ball loosening mechanism and a ball adding mechanism.

[0038] Specifically, a ball inlet is arranged at the top of the ball storage bin, and a ball outlet is arranged at the bottom of the ball storage bin.

[0039] The ball delivery mechanism is arranged at the goal entrance and is used for delivering the steel balls to be added to the ball storage bin.

[0040] The blocking sensor is set on the inner wall of the ball storage bin near the goal entrance to detect whether there is a ball stuck in the goal entrance. The detection principle of the blocking sensor is: when the running material blocks the goal entrance, the accumulated material exerts pressure on the inner wall of the ball storage bin near the goal entrance, causing the movable door in the blocking sensor to move and send out a signal. When the blocking material is cleared, the compression spring automatically restores the movable door to its original position.

[0041] The ball loosening mechanism is connected to the blocking sensor and is used to loosen the balls in the ball storage bin when a ball is stuck at the ball entry port.

[0042] The ball adding mechanism is connected to the ball outlet and is used for adding a part of the steel balls in the ball storage bin into the ball mill.

[0043] Furthermore, in a possible implementation, the bottom of the ball storage bin can be arranged tilted. By tilting the bottom of the ball storage bin, the steel balls in the ball storage bin can automatically move along the bottom of the ball storage bin toward the ball outlet under the action of gravity.

[0044] Further, in a possible implementation, the ball loosening mechanism can be configured as one or more vibrators. For example, a small electric vibrator or ultrasonic vibrator can be used, which can vibrate the outer wall or specific components of the ball storage bin to generate slight vibrations, thereby helping to loosen the steel ball stuck in the ball slot.

[0045] Of course, the present invention is not limited to this, and other types of equipment such as knocking equipment, rotating brushes, etc. can also be applied to the ball loosening mechanism of the present invention, as long as the desired effect of loosening the steel balls can be achieved.

[0046] Further, in a possible implementation, the ball transport mechanism may include a power motor, two rollers, a conveyor belt, and a plurality of ball claws, wherein the power motor is connected to the roller, the conveyor belt is arranged between the two rollers, and the plurality of ball claws are arranged on the conveyor belt at intervals.

[0047] Of course, the present invention is not limited to this, and other types of equipment such as chain transmission equipment, screw conveyors, vibrating conveying devices, etc. can also be applied to the ball conveying mechanism of the present invention, as long as the desired effect of conveying steel balls can be achieved.

[0048] Furthermore, in a possible embodiment, the ball adding mechanism can be configured as a material drop chute and a drum ball claw, and the ball outlet of the ball storage bin is connected to the drum ball claw through the material drop chute. The drum ball claw can be composed of a drum and a ball claw, wherein the drum is composed of an elongated cylindrical body, usually made of metal or wear-resistant material, and a series of spherical protrusions or tooth-like structures, called ball claws, are fixed on the surface of the drum. These ball claws can be made of metal or wear-resistant plastic. The main function of the drum ball claw is to transport materials or products through rolling motion. When the drum rotates, the ball claw will contact and push the material to transport it from one position to another. The ball claw with a spherical or tooth-like structure arranged on the surface of the drum can effectively grab and hold the material to prevent it from sliding or falling.

[0049] Furthermore, in another possible implementation, the ball adding mechanism can also be configured as a material drop chute and a baffle, and the ball outlet of the ball storage bin is connected to the baffle through the material drop chute. When it is necessary to add balls to the ball mill, the baffle can be lifted to input the steel balls from the material drop chute to the ball adding mechanism, and when there is no need to add balls to the ball mill, the baffle can be closed to temporarily store the steel balls in the material drop chute.

[0050] In addition, the drop chute can also be set at an angle, which is conducive to the steel balls automatically moving along the ball outlet of the ball storage bin toward the roller ball claws or baffles under the action of gravity.

[0051] Furthermore, in a possible implementation, the fully automatic grinding mill steel ball adding device may further include a buffer. The buffer is provided at the ball outlet to reduce the speed at which the steel ball enters the ball adding mechanism. Since the mass of the steel ball is relatively large, if the steel ball enters the ball adding mechanism at a relatively high speed, it is easy to cause damage to the ball adding mechanism. Therefore, the buffer may be provided to reduce the speed at which the steel ball enters the ball adding mechanism (such as the chute and the baffle, etc.).

[0052] For example, the buffer may be configured as a buffer roller, the inner surface of which may be covered with a damping material having a high friction coefficient, such as rubber or polyurethane, for absorbing part of the kinetic energy of the steel ball, thereby slowing down the speed of the steel ball.

[0053] For another example, the buffer can be configured as a reducer, such as a gear reducer or a chain drive reducer, which can slow down the speed at which the steel balls are discharged by changing the transmission ratio, thereby achieving a buffering effect.

[0054] Of course, the present invention is not limited to this, and other types of buffering devices such as cylinder damping devices, spring buffering devices, hydraulic buffering devices, etc. can also be applied to the buffer of the present invention as long as the desired buffering effect can be achieved.

[0055] Furthermore, in a possible implementation, the fully automatic grinding mill steel ball adding device may further include a ball counter, which is disposed at the ball outlet end of the ball adding mechanism and is used to measure the number of steel balls output from the fully automatic grinding mill steel ball adding device.

[0056] Furthermore, in a possible implementation, the fully automatic grinding mill steel ball adding device may further include at least one ball position sensor. The ball position sensor is arranged on the inner side wall of the ball storage bin and is used to detect the storage height of the steel balls in the ball storage bin.

[0057] In order to better understand the above exemplary embodiments of the present invention, they are further described below in conjunction with specific examples and drawings.

[0058] like Figure 1 As shown, a fully automatic grinding mill steel ball adding device consists of a conveyor belt 3, a motor 4, a ball claw 5, a ball storage bin 6, a material blocking sensor 7, a vibrator 8, a buffer 9, a material drop chute 10, a roller ball claw 11, a high-level sensor 12, a low-level sensor 13 and a ball counter 14.

[0059] Among them, the top of the ball storage bin 6 is provided with a goal entrance, the bottom of the ball storage bin 6 is provided with a ball outlet, and an inclined bottom plate is provided at the bottom of the ball storage bin 6, and a bracket for supporting the bottom plate is provided below the bottom plate. One end of the conveyor belt 3 is provided at the goal entrance of the ball storage bin 6, and the other end of the conveyor belt 3 is provided in the ball storage box 1. The ball storage box 1 stores a plurality of steel balls 2 to be added, and the ball storage box 1 has a certain height difference with the goal entrance of the ball storage bin 6, and the steel balls 2 need to be transferred to the ball storage bin 6 through the conveyor belt 3. The motor 4 is connected to the conveyor belt 3 to provide the power required for the conveyor belt to transfer the steel balls. A plurality of ball claws 5 are arranged at intervals on the surface of the conveyor belt 3 to fix the position of the steel balls 2 on the conveyor belt 3. A blocking sensor 7 is provided on the side wall below the goal entrance of the ball storage bin 6 to detect whether there is a stuck ball at the goal entrance. A vibrator 8 is provided on the bottom plate of the ball storage bin 6, and the vibrator 8 is used to loosen the balls when a stuck ball occurs. The ball outlet of the ball storage bin 6 is connected to the roller ball claw 11 through the drop chute 10, and a buffer 9 is also provided at the ball outlet of the ball storage bin 6 to buffer the speed of the steel ball entering the drop chute 10. A high position sensor 12 and a low position sensor 13 are provided on the side wall of the ball storage bin 6, and a ball counter 14 is provided at the ball outlet end of the roller ball claw 11.

[0060] Embodiment 2

[0061] The second embodiment of the utility model provides a fully automatic grinding mill steel ball adding system, which comprises: a ball storage box, a ball adding controller and the fully automatic grinding mill steel ball adding device in the above embodiment.

[0062] Specifically, one end of the fully automatic mill steel ball adding device is connected to a ball storage box, and the other end of the fully automatic mill steel ball adding device is connected to a ball adding controller. The ball storage box is placed on the ground and is used to store the steel balls to be added. The ball adding controller is used to control the fully automatic mill steel ball adding device to complete the ball adding according to the specified steel ball adding amount according to the real-time feeding amount of the ball mill and the current of the ball mill. The ball adding controller is also used to control the ball loosening mechanism to loosen the balls in the ball storage bin according to the detection signal of the blocking sensor.

[0063] When the fully automatic mill steel ball adding device is working, the steel balls in the ball storage box on the ground can be automatically transported to the ball storage bin. When the fully automatic mill steel ball adding device is needed to add balls, the steel ball specific gravity and ball consumption ratio are manually set on the DCS or on-site controller, and the fully automatic mill steel ball adding device is started. The fully automatic mill steel ball adding device is controlled by the ball adding controller to automatically add steel balls according to the set time or quality. The ball adding controller can accurately collect the limestone processing volume of the weighing feeder belt scale or the DCS control system, and accurately calculate the amount of steel balls added per unit time in combination with the steel ball parameters and ball consumption ratio set on the DCS system or the fully automatic mill steel ball adding device.

[0064] The control logic of the ball adding controller for the fully automatic grinding mill steel ball adding device is as follows: when the weighing feeder is running, the cumulative instantaneous feeding amount per hour is intelligently predicted through a functional relationship, and the baseline amount of steel balls to be added + the deviation between the rated current of the mill and the actual operating current is corrected to correct the amount of steel balls added; when the accumulated amount of steel balls is greater than 1, a command is issued to open the on-site actuator once, and when the on-site sensor captures the steel ball adding signal, a closing command is issued to move the actuator; each successful addition of steel balls accumulates once.

[0065] Of course, the fully automatic grinding mill steel ball adding device can also be switched to manual mode at any time to continuously add steel balls to the ball mill, and accumulate historical values ​​and current values ​​on the display.

[0066] Furthermore, in a possible implementation, the system may further include an alarm, which is connected to the fully automatic grinding mill steel ball adding device and the ball adding controller, respectively, and is used to provide different levels of sound and light alarms according to different types of system failure conditions. Here, different types of system failure conditions may include insufficient ball storage bin, operation failure of the fully automatic grinding mill steel ball adding device, and network communication failure.

However, the present invention is not limited to the specific details in the above embodiments.

[0068] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0069] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
