Description

Technical Field

[0001] The utility model belongs to the field, and specifically relates to a pigment grinding discharge flow control system. Background Art

[0002] Pigments are fine powdered solid substances that are insoluble in the paint base. When dispersed in the paint, they impart or enhance certain properties of the paint. These properties include color, hiding power, durability, mechanical strength, and corrosion resistance to metal substrates. After the pigment is ground and refined, the pigment needs to be transferred. However, during the transfer process of existing pigments, the discharge and feeding progress of the pigments are prone to be different, resulting in intermittent pigment delivery, which is not conducive to the subsequent processing of the pigments. In addition, the heat generated by the pigment during grinding can easily vaporize the pigment, resulting in blockage of the pigment feed port. Summary of the invention

The first pressure pump 222, the first control valve 120, the first flow valve 211 and the second flow valve 221 are all electrically connected to the control panel 300.

[0021] Furthermore, the pigment grinding discharge flow control system includes a liquid level sensor 230, which is arranged at the upper end of the transfer cylinder 200, and the lower end of the liquid level sensor 230 is correspondingly arranged at the lower end of the transfer cylinder 200, and the liquid level sensor 230 is electrically connected to the control panel 300.

[0022] Furthermore, a first detection tube 250 is provided at one end of the transfer cylinder 200, and the first detection tube 250 is a transparent tube. A first connecting port 241 is provided at the upper end of the transfer cylinder 200, and a first connecting portion 251 is provided at the upper end of the first detection tube 250, and the first connecting portion 251 is sealed and connected to the first connecting port 241. A second connecting port 242 is provided at the lower end of the transfer cylinder 200, and a second connecting portion 252 is provided at the lower end of the first detection tube 250, and the second connecting portion 252 is sealed and connected to the second connecting port 242.

[0024] Working principle: After being processed in the previous process, the pigment enters the grinder 100 through the first feed port 130, and is further ground by the grinder 100 in the grinder 100. Then, it is sent to the transfer cylinder 200 under the control of the first control valve 120. The liquid level sensor 230 can detect the liquid level height in the transfer cylinder 200. When the liquid level in the transfer cylinder 200 decreases, the first control valve 120 opens or replaces another grinder 100 to ensure that there is a certain amount of pigment remaining in the transfer cylinder 200, thereby ensuring that the subsequent processing of the pigment will not be intermittent and will be more stable.

[0025] When the pigment passes through the grinder 100, a large amount of heat is generated when the grinder 100 is working, which may cause part of the pigment to vaporize and enter the first feed port 130, which may easily cause the pigment to flow back and cause the first feed port 130 to be blocked. The liquid level of the pigment in the transfer cylinder 200 can also be directly observed through the first detection tube 250, which can be manually checked to avoid unstable pigment discharge.
