Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, specifically to a grinding media addition device. Background Technology

[0002] Mills such as fine grinding equipment and ultrafine grinding equipment require the addition of grinding media such as ceramic particles during operation. These grinding media grind and peel the ore, thus grinding it to the required size range. Since the size of the grinding media decreases as grinding progresses, and some grinding media is lost with the slurry, the size and quantity of the grinding media directly affect the grinding effect. Therefore, a specified amount of ceramic particles needs to be added to the mill at regular intervals.

[0003] In related technologies, a hopper is used to hold ceramic particles, and an electronic scale is installed at the outlet of the hopper. A conveyor belt leading to the mill is located below the electronic scale. Ceramic particles are released through the hopper, and their weight is measured on the electronic scale. The conveyor belt then transports the required weight of ceramic particles to the mill. However, ceramic particles are prone to jamming and clogging in the hopper, preventing them from being discharged smoothly. Simultaneously, some ceramic particles accumulate on the electronic scale, and the quantity of accumulated particles is unstable. Therefore, determining the quantity of added ceramic particles by weighing with the electronic scale is inaccurate, resulting in unstable particle size of the ground ore. Utility Model Content

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is for reference. Figure 1 This invention describes a grinding media addition device according to an embodiment of the present invention.

[0028] like Figure 1 As shown, the grinding media adding device of this utility model embodiment includes a hopper 1, a liquid supply pipe 2, a weighing sensor and a conveying pipe 3.

[0029] The hopper 1 is used to contain grinding media. Specifically, the grinding media is preferably, but not limited to, ceramic particles, and the diameter of the ceramic particles is preferably, but not limited to, 1 mm to 4 mm.

[0030] The liquid supply pipe 2 is connected to the hopper 1 and is used to supply liquid medium to the hopper 1. Specifically, as follows: Figure 1 As shown, the liquid supply pipe 2 can be configured such that its outlet end extends into the interior of the hopper 1 or is installed on the wall of the hopper 1, or its outlet end is positioned opposite to the top inlet of the hopper 1. The liquid medium is preferably, but not limited to, water.

[0031] Weighing sensor ( Figure 1(Not shown) is connected to hopper 1 and is used to obtain the total weight of hopper 1 and the medium inside hopper 1. Specifically, the medium inside hopper 1 can be only grinding media, or it can be a mixture of grinding media and liquid media.

[0032] The conveying pipe 3 is operably connected to the outlet of the hopper 1, and the outlet end of the conveying pipe 3 is used to communicate with the mill 4. Specifically, the outlet of the hopper 1 is operably connected to the conveying pipe 3 to provide a mixture of liquid medium and grinding medium to the conveying pipe 3 when connected, and to stop providing the mixture of liquid medium and grinding medium to the conveying pipe 3 when disconnected, thereby enabling controlled supply of grinding medium according to the operating requirements of the mill 4. The outlet end of the conveying pipe 3 can be configured to extend into the mill 4 or be located on the wall of the mill 4, or it can be configured to be opposite to the opening of the mill 4. The mill 4 is preferably, but not limited to, a fine grinding device and an ultrafine grinding device, and more preferably an ultrafine grinding device.

[0033] When the grinding media adding equipment is running, the liquid supply pipe 2 supplies liquid media into the hopper 1. The outlet of the hopper 1 is connected to the conveying pipe 3 so that the mixture of grinding media and liquid media in the hopper 1 is supplied to the conveying pipe 3 and then to the mill 4 through the conveying pipe 3, thereby ensuring that the grinding media is smoothly supplied from the hopper 1 to the mill 4.

[0034] Meanwhile, the weighing sensor acquires the total weight of hopper 1 and the mixture of grinding media and liquid media inside hopper 1. Since the rate at which liquid media is fed into hopper 1 and the rate at which it is discharged from hopper 1 can be preset and measured, the weight of grinding media discharged from hopper 1 can be calculated by acquiring the total weight through the weighing sensor. When the weight of grinding media discharged from hopper 1 reaches the requirements of mill 4, the outlet of hopper 1 and the conveying pipe 3 are disconnected, thereby accurately supplying the mill 4 with the required weight and quantity of grinding media.

[0035] The grinding media adding device of this utility model supplies liquid media to the hopper through a supply pipe. The liquid media carries the grinding media out of the hopper and is then supplied to the mill through a conveying pipe, ensuring smooth delivery of the grinding media and avoiding material jamming or blockage in the hopper and conveying pipe. A weighing sensor obtains the total weight of the hopper and the media within it, thereby accurately determining the weight of the grinding media discharged from the hopper.

[0036] In some embodiments of the present invention, the grinding media adding device further includes a support frame ( Figure 1 (Not shown in the image) The support frame is equipped with a horizontally arranged support platform, which supports the hopper 1. A weighing sensor is located between the support platform and the hopper 1, thereby enabling the acquisition of the total weight of the hopper 1 and the medium inside the hopper 1.

[0037] In some embodiments, the grinding media adding device of this utility model further includes a pressure supply component 5, which is connected to the conveying pipe 3 and is used to supply liquid media with a certain pressure to the conveying pipe 3. Along the flow direction of the medium in the conveying pipe 3, the outlet of the pressure supply component 5 and the outlet of the hopper 1 are sequentially connected to the conveying pipe 3.

[0038] like Figure 1 As shown, the mixture of grinding media and liquid media in the conveying pipe 3 moves from left to right. The pressure supply component 5 is connected to the conveying pipe 3 and is located upstream of the outlet of the hopper 1, along the flow direction of the mixture in the conveying pipe 3. In other words, the connection point of the pressure supply component 5 and the conveying pipe 3 is located to the left of the connection point between the outlet of the hopper 1 and the conveying pipe 3. The pressure supply component 5 is used to supply liquid media with a certain pressure to the conveying pipe 3 to push the mixture in the conveying pipe 3 towards the mill 4, ensuring that the grinding media discharged from the hopper 1 completely and smoothly enters the mill 4.

[0039] The liquid medium supplied by the pressure supply component 5 to the conveying pipe 3 can be the same as or different from the liquid medium supplied by the liquid supply pipe 2 to the hopper 1, but is preferably the same.

[0040] In some embodiments, the pressure supply assembly 5 includes a connected pipe body 51 and a variable frequency pipeline pump 52. The inlet end of the pipe body 51 is connected to the liquid supply pipe 2, and the outlet end of the pipe body 51 or the outlet end of the variable frequency pipeline pump 52 is connected to the delivery pipe 3.

[0041] like Figure 1 As shown, the pressure supply assembly 5 includes a pipe body 51 and a variable frequency pipeline pump 52. The inlet end of the pipe body 51 is connected to the liquid supply pipe 2 to supply liquid medium into the pipe body 51 through the liquid supply pipe 2. The variable frequency pipeline pump 52 can be installed on the pipe body 51 and located between the two ends of the pipe body 51, or it can be connected to the outlet end of the pipe body 51.

[0042] When the variable frequency pipeline pump 52 is installed on the pipe body 51 and located between the two ends of the pipe body 51, the outlet end of the pipe body 51 is connected to the delivery pipe 3.

[0043] When the variable frequency pipeline pump 52 is connected to the outlet end of the pipe body 51, the inlet end of the variable frequency pipeline pump 52 is connected to the outlet end of the pipe body 51, and the outlet end of the variable frequency pipeline pump 52 is connected to the delivery pipe 3.

[0044] Preferably, the variable frequency pipeline pump 52 is installed on the pipe body 51 and located between the two ends of the pipe body 51. The outlet end of the pipe body 51, the outlet of the hopper 1, and the inlet end of the conveying pipe 3 are connected by a tee.

[0045] When the grinding media adding equipment is running, a portion of the liquid media supplied by the liquid supply pipe 2 enters the hopper 1 and carries the grinding media in the hopper 1 into the conveying pipe 3. Another portion of the media supplied by the liquid supply pipe 2 enters the pipe body 51 and, after passing through the variable frequency pipeline pump 52, has a certain speed and pressure. Then, it enters the conveying pipe 3, which drives the grinding media discharged from the hopper 1 to move towards the mill 4 and finally enters the mill 4.

[0046] Therefore, the variable frequency pipeline pump 52 is used to adjust the rate at which the grinding media enters the mill 4, so as to add the grinding media to the mill 4 quantitatively and uniformly, and ensure the stability of the particle size of the output of the mill 4.

[0047] Furthermore, the variable frequency pipeline pump 52 includes a motor, a frequency converter, a booster pump, and an impeller. The booster pump has an inlet end and an outlet end of the variable frequency pipeline pump 52 and is connected to the pipe body 51. The impeller is located inside the booster pump, and the motor is located on the booster pump and connected to the impeller to drive the impeller to rotate. The frequency converter is connected to the motor to adjust the speed of the motor and the impeller, thereby adjusting the speed of the liquid medium passing through the booster pump and giving the liquid medium a certain pressure. Therefore, by adjusting the frequency of the frequency converter, the speed of the liquid medium supplied from the pipe body 51 to the delivery pipe 3 can be adjusted, thereby adjusting the rate at which the grinding media enters the mill 4.

[0048] Preferably, the booster pump is configured with a high head and low flow rate; more preferably, the booster pump has a head of 70m to 90m, such as 70m, 80m, or 90m, and a flow rate of 12m³ / h. 3 / h~14m 3 / h, for example, 12m 3 / h、13m 3 / h, 14m 3 / h etc.

[0049] It is understood that the variable frequency pipeline pump 52 is not limited to including a pressurization pump; in other embodiments, the variable frequency pipeline pump 52 includes a peristaltic pump or a centrifugal pump.

[0050] In some embodiments of the present invention, the grinding media adding device further includes a terminal ( Figure 1 (Not shown in the image) The terminal is electrically connected to the weighing sensor to receive the total weight obtained by the weighing sensor, thereby obtaining the rate at which the grinding media is discharged from the hopper 1. The terminal is also electrically connected to the variable frequency pipeline pump 52 to adjust the frequency of the variable frequency pipeline pump 52 according to the rate at which the grinding media is discharged from the hopper 1.

[0051] Specifically, the terminal is preferably, but not limited to, a controller, a computer, etc.

[0052] The terminal is electrically connected to the weighing sensor to receive the total weight of hopper 1 and the mixture of grinding media and liquid media inside hopper 1, which is acquired and transmitted by the weighing sensor. The rate at which liquid media is fed into hopper 1 and the rate at which it is discharged from hopper 1 can be preset or measured. The rates at which liquid media is fed into hopper 1 and discharged from hopper 1 are input to the terminal in advance.

[0053] During the use of the grinding media adding equipment, the terminal can calculate the weight of the grinding media discharged from hopper 1 in real time based on the total weight obtained by the weighing sensor in real time, and further calculate the rate at which the grinding media is discharged from hopper 1 based on the rate at which the input liquid media is fed into hopper 1 and the rate at which the input liquid media is discharged from hopper 1.

[0054] The terminal is electrically connected to the variable frequency pipeline pump 52 to adjust the frequency of the variable frequency pipeline pump 52 according to the rate at which the grinding medium is discharged from the hopper 1 and the supply rate of the grinding medium required by the mill 4 that is pre-input to the terminal, so that the grinding medium in the conveying pipe 3 enters the mill 4 at the supply rate required by the mill 4, thereby ensuring the stability of the particle size of the output of the mill 4.

[0055] Furthermore, the terminal is electrically connected to the mill 4. The mill 4 can obtain the linear particle size of the ore particles inside it and transmit the linear particle size to the terminal. The terminal analyzes the received linear particle size to obtain the required supply rate of grinding media for the mill 4 and adjusts the frequency of the variable frequency pipeline pump 52 accordingly.

[0056] In some embodiments, the grinding media adding device of this utility model further includes a first valve 6, which is disposed on the liquid supply pipe 2 and located upstream of the inlet end of the pipe body 51 along the medium flow direction in the liquid supply pipe 2.

The first valve 6 is located on the left side of the connection position between the inlet end of the pipe body 51 and the liquid supply pipe 2. In other words, along the flow direction of the medium in the liquid supply pipe 2, the first valve 6 is located upstream of the inlet end of the pipe body 51.

[0058] When the first valve 6 is opened, the liquid medium in the supply pipe 2 is simultaneously supplied to the hopper 1 and the pipe body 51. When the first valve 6 is closed, the liquid medium in the supply pipe 2 is simultaneously stopped from supplying the hopper 1 and the pipe body 51. The supply of liquid medium is controlled by opening and closing the first valve 6, thereby controlling the supply of grinding media.

[0059] The first valve 6 can be opened and closed manually or automatically.

[0060] Preferably, the terminal is electrically connected to the first valve 6 to control the opening and closing of the first valve 6. In other words, the first valve 6 is opened and closed automatically via the terminal.

[0061] More preferably, during the use of the grinding media adding equipment, the terminal first controls the opening of the first valve 6, and then adjusts the frequency of the variable frequency pipeline pump 52.
