Further, the connection between feed pump 1 and buffer tank 3 and the connection between feed pump 1 and storage tank 100 are connected by butt-welding straight-through joint. Butt-welding straight-through joint is installed on feed pump 1, buffer tank 3 and storage tank 100, and two butt-welding straight-through joints are connected by pipeline, so that feed pump 1 can be disassembled and repaired.

The material is transported to the buffer tank 3 under the action of the feed pump 1 and then transported from the buffer tank 3 to the metering tank 5. Further, the buffer tank 3 has a large volume and can be separated from other structures during transportation to avoid damage caused by instability of the buffer tank 3 during transportation. In one or more embodiments, a liquid level gauge 4 is arranged in the buffer tank 3 to detect the liquid level in the buffer tank 3. Specifically, the liquid level gauge 4 is installed in the buffer tank 3 by a sleeve to facilitate adjustment of the installation height of the liquid level gauge 4. Further, the liquid level gauge 4 is pre-set with a high threshold and a low threshold. The high threshold and the low threshold are adjusted and set according to actual needs. The liquid level gauge 4 is linked with the feed pump 1 and the air source valve 2. When the liquid level gauge 4 detects that the liquid level in the buffer tank 3 reaches the low threshold, the air source valve 2 is opened and the feed pump 1 is operated to pump the material from the storage tank 100 into the buffer tank 3. When the liquid level reaches the high threshold, the air source valve 2 is closed and the feed pump 1 stops operating.

[0031] Continuing to refer to Figure 1 In one or more embodiments, a tank opening is formed in the metering tank 5, the tank opening is in communication with the second opening through a feeding pipeline, and a feeding valve 6 is arranged on the feeding pipeline. Specifically, the feeding valve 6 is sealingly connected to the metering tank 5 and the buffer tank 3 through a metal hose, and the metal hose has a certain degree of freedom to ensure the accuracy of the weighing of the metering tank 5. The feeding valve 6 is connected in a straight-through manner at both ends to facilitate installation and maintenance of the feeding valve 6. Further, the metering tank 5 is connected with a weight detector 11 for detecting the weight of the material in the metering tank 5. Specifically, the weight detector 11 is installed directly below the metering tank 5, and the tank opening of the metering tank 5 is connected through a metal hose which has a certain degree of freedom to ensure the accuracy of the weighing of the metering tank 5. Further, the weight detector 11 is pre-set with an upper threshold and a lower threshold, which are adjusted and set according to actual needs. The weight detector 11 is linked with the feeding valve 6. When the weight detector 11 detects that the weight of the material in the metering tank 5 reaches the lower threshold, the feeding valve 6 is opened, and the material flows from the buffer tank 3 into the metering tank 5. When the weight of the material in the metering tank 5 reaches the upper threshold, the feeding valve 6 is closed. Further, a manual pipeline is arranged between the buffer tank 3 and the metering tank 5 to manually control the opening and closing of the pipeline, so that the material in the buffer tank 3 flows into the metering tank 5.

[0032] Continuing to refer to Figure 1The connecting pipeline is communicated with the material spraying pump 8 at one end and with the material supplementing pipeline at the other end. Further, the filter 7 is arranged on the connecting pipeline. Specifically, the filter 7 is a clamp split type filter 7. The clamp split type filter 7 generally comprises a cylinder body and an integrated stainless steel filter core. The cylinder body is provided with a blowdown valve at the bottom, and the filter core can be pulled out integrally from the top, thereby facilitating cleaning of the filter core. Further, a set value is preset in the weight detector 11, and the set value is set by the staff according to the formula; the material spraying pump 8 is linked with the weight detector 11, and when the staff manually opens the material spraying pump 8 or the material spraying pump 8 receives the feedback signal of the mixer 200, the material spraying pump 8 is opened to spray the material; when the weight detector 11 detects that the weight reduction of the material in the metering tank 5 reaches the set value, the material spraying pump 8 is closed, and one batch of material spraying is completed. With the execution of the batch, the material in the metering tank 5 gradually reduces, and when it is less than the lower threshold value, the material will be automatically supplemented. Further, the material supplementing valve 6 is linked with the material spraying pump 8, and the material supplementing valve 6 is closed when the material spraying pump 8 is opened, and the material spraying pump 8 is closed when the material supplementing valve 6 is opened, that is, the automatic material supplementing function is disabled during the material spraying period, and for the same reason, the automatic material spraying function is also disabled during the automatic material supplementing period. The material supplementing time of the metering tank 5 is less than 5 min, which does not affect the normal production at all. This interlocking function can ensure the independence of the material supplementing and spraying functions and ensure the accuracy of metering. Further, the material spraying pump 8 is a rotary vane pump, and the material spraying pump 8 is connected with a material discharging pipeline. The material spraying pump 8, the connecting pipeline and the material discharging pipeline are all connected through butt-welding type straight-through joints, which facilitates on-site piping with the mixer 200. Further, the material discharging pipeline is provided with a spray head at the end away from the material spraying pump 8. The spray head is installed inside the mixer 200 and maintains a certain height with the material, avoiding contact between the spray head and the overturned material when the mixer 200 is stirred, so as to reduce the uniformity of the mixed material. The number of the spray heads is matched with the flow of the material spraying pump 8, avoiding the addition of the material before it is atomized, so as to reduce the uniformity of the mixed material. Further, the material spraying valve 9 is arranged on the material discharging pipeline and is linked with the material spraying pump 8; the material spraying valve 9 is opened when the material spraying pump 8 is opened and is closed when the material spraying pump 8 is closed. Further, the straight-through pipeline 10 is arranged between the material spraying pump 8 and the buffer tank 3, and the valve is arranged on the straight-through pipeline 10, so that the material can be transported into the buffer tank 3 through the straight-through pipeline 10 to adjust the concentration of the material in the buffer tank 3.
