Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinder buffer tank monitoring system. Background Art

[0002] In industrial production, grinding equipment such as grinders are usually used to perform preliminary grinding of raw materials to reduce the particle size of the materials, increase the specific surface area of ​​the materials, and create good conditions for subsequent further processing or chemical reactions. Grinding machines are widely used in energy, metallurgy, chemicals, building materials and other industries. Grinding machines usually need to be used together with buffer tanks. For example, in the grinding process of lithium iron phosphate cathode materials, the grinder buffer tank provides temporary transfer buffer space for the slurry during the operation of the grinder, which is used to coordinate the working frequency of the front-end and back-end equipment, ensure that the slurry is stable and continuously enters the subsequent process, and effectively avoid the overall production progress being affected by the untimely or unstable supply of slurry.

[0003] For example, the utility model patent with application number CN201721683698.7 proposes a coarse grinding buffer device in the beverage processing process, which includes two main parts: a grinder and a buffer tank. The grinder and the buffer tank are connected through a connecting pipe, and the bottom of the buffer tank is provided with a stirring device, a discharge pipe, a control valve and other components.

[0004] However, when the material enters the buffer tank from the grinder, due to the lack of flow control, the flow rate cannot be flexibly adjusted, which can easily cause the buffer tank's feed rate to exceed its discharge rate, and the buffer tank's internal pressure to be too high. When the buffer tank exceeds the pressure limit, the buffer tank will spray, resulting in production stagnation and material loss. In severe cases, it will also cause pollution and damage to the surrounding environment and equipment. Utility Model Content

[0005] In view of this, it is necessary to provide a grinding mill buffer tank monitoring system to solve the problem of being unable to control the inlet and outlet rate ratio of the buffer tank.

[0006] The utility model provides a grinding machine buffer tank monitoring system, which is used for a connected grinding machine and a buffer tank, and includes a control component, wherein the control component includes a controller and a detection component, wherein the detection component has a detection end built into the buffer tank, and the detection end is used to detect the liquid level and / or pressure in the buffer tank, and the controller is electrically connected to the detection component to receive the liquid level signal and / or pressure signal detected by the detection end, and the controller is electrically connected to the grinding machine to control the action of the grinding machine according to the liquid level signal and / or pressure signal, so as to control the feeding rate of the buffer tank.

[0007] Furthermore, the detection element is a liquid level sensor and / or a pressure sensor.

[0008] Furthermore, the control component also includes a protective member, which is electrically connected to the grinder to detect the current and / or power of the grinder. The controller is electrically connected to the protective member to receive the current signal and / or power signal detected by the protective member, and controls the operation of the grinder according to the current signal and / or power signal.

[0009] Furthermore, the protective element is a current sensor and / or a power sensor.

[0010] Furthermore, the feed port of the buffer tank is connected to the discharge port of the grinder via a feed pipe.

[0011] Furthermore, a feed control valve is installed on the feed pipe, and the controller is electrically connected to the feed control valve. When the liquid level signal and / or the pressure signal is greater than a preset range value, the controller controls the opening and closing degree of the feed control valve to become smaller; when the liquid level signal and / or the pressure signal is less than the preset range value, the controller controls the opening and closing degree of the feed control valve to increase.

[0012] Furthermore, a feed flow meter is installed on the feed pipe.

[0013] Furthermore, the discharge port of the buffer tank is connected to a discharge pipe.

[0014] Furthermore, a discharge control valve is installed on the discharge pipe, and the controller is electrically connected to the discharge control valve. When the liquid level signal and / or the pressure signal is greater than a preset range value, the controller controls the opening and closing degree of the feed control valve to become larger; when the liquid level signal and / or the pressure signal is less than the preset range value, the controller controls the opening and closing degree of the feed control valve to become smaller.

[0015] Furthermore, a discharge flow meter is installed on the discharge pipe.

[0016] Compared with the prior art, the liquid level and / or pressure in the buffer tank can be detected by the detection end of the detection part, and the controller controls the action of the grinder according to the detected liquid level signal and / or pressure signal. Specifically, when the liquid level signal and / or pressure signal is greater than a preset value, the controller reduces the working power of the grinder, and the discharge rate of the grinder is reduced, that is, the feed rate of the buffer tank is reduced, thereby reducing the liquid level and / or pressure in the buffer tank. Similarly, when the liquid level signal and / or pressure signal is less than a preset value, the controller increases the working power of the grinder, and the discharge rate of the grinder is increased, that is, the feed rate of the buffer tank is increased, thereby increasing the liquid level and / or pressure in the buffer tank, thereby effectively managing the feed and discharge rate ratio of the buffer tank.

[0020] During implementation, the liquid level and / or pressure in the buffer tank 200 can be detected by the detection end of the detection member 320, and the controller 310 controls the operation of the grinder 100 according to the detected liquid level signal and / or pressure signal. Specifically, when the liquid level signal and / or pressure signal is greater than a preset value, the controller 310 reduces the working power of the grinder 100, and the discharge rate of the grinder 100 is reduced, that is, the feed rate of the buffer tank 200 is reduced, thereby reducing the liquid level and / or pressure in the buffer tank 200. Similarly, when the liquid level signal and / or pressure signal is less than a preset value, the controller 310 increases the working power of the grinder 100, and the discharge rate of the grinder 100 is increased, that is, the feed rate of the buffer tank 200 is increased, thereby increasing the liquid level and / or pressure in the buffer tank 200, thereby effectively controlling the feed and discharge rate ratio of the buffer tank 200.

[0021] The grinder 100 and the buffer tank 200 in this embodiment are connected, and the discharge rate of the grinder 100 is the same as the feed rate of the buffer tank 200. In order to facilitate the control of the feed and discharge rate ratio of the buffer tank 200, the system is implemented through a control component 300.

[0022] The control component 300 in this embodiment includes a controller 310 and a detection component 320.

The controller 310 is electrically connected to the pressure sensor 322 to receive the current signal and / or power signal detected by the pressure sensor 322, and control the operation of the grinder 100 according to the current signal and / or power signal.

At the same time, the controller 310 can reduce the feed speed and / or grinding time of the grinder 100 to avoid overload and damage to the equipment.

[0027] In one embodiment, the pressure sensor 322 is a current sensor 331 and / or a power sensor 332. The current sensor 331 may be a sensor of Sugon-CR1000, and the power sensor 332 may be a sensor of Agilent-E9301B.

[0028] The feed port of the buffer tank 200 in this embodiment is connected to the discharge port of the grinder 100 via a feed pipe 210 .

[0029] Among them, a feed control valve 211 is installed on the feed pipe 210, and the controller 310 is electrically connected to the feed control valve 211.
