Description

Technical Field

[0001] The utility model relates to the technical field of unloading devices, in particular to a unloading device for grinding aid stock solution. Background Art

[0002] Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It can significantly increase the hourly output of cement, the strength of cement at all ages, and improve its fluidity. Cement grinding aid can significantly reduce the electrostatic adsorption ball phenomenon formed during the grinding process, and can reduce the tendency of ultrafine particles formed during the grinding process to aggregate again. Cement grinding aid can also significantly improve cement fluidity, improve the grinding effect of the mill and the powder selection efficiency of the powder selector, thereby reducing grinding energy consumption.

[0003] At present, in the early stage of production, liquid grinding aids need to be stirred in a mixing tank for a certain period of time to produce a stock solution for preparing grinding aids. After the stirring is completed, the stock solution needs to be discharged from the mixing tank and loaded into a storage barrel. The existing method of discharging the grinding aid stock solution is mainly to manually control the opening and closing of the valve to input the stock solution in the mixing tank into the storage barrel. When the valve is opened, a large amount of stock solution gushes out from the discharge port, and the amount of discharge cannot be effectively controlled, resulting in the valve closing too late or too early, making the stock solution easy to spill during the operation process, resulting in a waste of stock solution; or the valve needs to be opened and closed continuously until the storage barrel is filled, which reduces the unloading efficiency of the stock solution to a certain extent.

[0032] Example 1

[0033] The utility model provides a discharging device for grinding aid stock solution, such as Figure 1 As shown, the raw liquid after mixing in the stirring tank flows out from the discharge port 1 and enters the upper pipe 5 connected to the discharge port 1, and the discharge pipe 4 is driven by the driving device to move on the bracket, so that the lower pipe 6 and the discharge pipe 4 are in the starting position; at this time, the lower outlet 11 is connected to the lower pipe 6, and the first cover plate 12 is not in contact with the upper end of the lower pipe 6, so that the raw liquid drives the first cover plate 12 to rotate on the support plate 7 through its own gravity acting on the first cover plate 12, so that the raw liquid passes through the upper outlet 10 and flows into the temporary storage chamber 8 formed by the combination of the lower pipe 6 and the discharge pipe 4; at the same time, because the second cover plate 13 is in contact with the support 3, the lower outlet 11 is in a closed state, preventing the raw liquid in the temporary storage chamber 8 from flowing to the outside;

[0034] When the stock liquid fills the temporary storage chamber 8, the driving device drives the discharge pipe 4 to move on the support 3, so that the lower pipe 6 and the discharge pipe 4 are in the discharge position; at this time, the first cover plate 12 contacts the upper end surface of the lower pipe 6, so that the first cover plate 12 rotates on the support plate 7 until the upper outlet 10 is in a closed state, so as to prevent the stock liquid from flowing from the upper pipe 5 to the outside; at the same time, the second cover plate 13 slides out from the support 3, so that the lower outlet 11 corresponds to the feed port 2, and the gravity of the stock liquid acting on the second cover plate 13 drives the second cover plate 13 to rotate on the sealing cover, so that the stock liquid flows out from the lower outlet 11 and flows into the storage barrel through the feed port 2; thereby, a certain amount of stock liquid is stored in the temporary storage chamber 8, and then the stock liquid is introduced from the temporary storage chamber 8 into the storage barrel, so as to realize the quantitative discharge of the discharge device, better control the amount of stock liquid discharge, and avoid the waste of stock liquid caused by spilling of the stock liquid; at the same time, there is no need to continuously open and close the valve until the storage barrel is filled, thereby improving the discharge efficiency of the stock liquid.

[0035] Example 2

[0036] Based on Example 1, Figure 1 and Figure 3 As shown, when the volume cover of the storage barrel is opened, a force greater than the resistance between the ball 25 and the groove 24 can be applied to push the support plate 7 upward, so that the support plate 7 contacts the inclined surface 18 of the next support block 17, and the component force generated after the contact drives the support block 17 to slide inward, and compresses the return spring 19 until the support plate 7 moves upward to the specified position. At this time, the corresponding support block 17 is driven to slide out again under the action of the rebound force of the return spring 19, so that its upper end surface contacts the support plate 7, thereby changing the capacity of the temporary storage chamber 8 and changing the amount of inclined material of the unloading device at one time, so as to meet the unloading needs of storage barrels of different volumes; when it is necessary to move the support plate 7 downward, move the vertical block 16 to both sides until the support block 17 no longer contacts the support plate 7, so that the support plate 7 can slide between the vertical blocks 16 at will, thereby changing the capacity of the temporary storage chamber 8.

[0037] Example 3

[0038] Based on Example 2, Figure 1 and Figure 4 As shown, since the adjusting block 22 is threadedly connected to the upper pipe 5, the adjusting block 22 is moved on the upper pipe 5 by rotating it on the upper pipe 5, thereby changing the position of the adjusting block 22, changing the compression amount of the clamping spring 23, and changing the rebound force applied by the clamping spring 23 on the sealing gasket 21, so that the sealing gasket 21 is squeezed by the clamping spring 23 and fully deformed, and fits with the side walls of the upper pipe 5 and the discharge port 1 respectively, further strengthening the sealing between the upper pipe 5 and the discharge port 1, and preventing the raw liquid from flowing out of the gap to the outside; similarly, strengthening the sealing between the lower pipe 6 and the discharge pipe 4.

[0039] Example 4

[0040] Based on Example 2, Figure 1 and Figure 2 As shown, the driving rod 29 is driven to rotate along the rotating cylinder 27 as the center by the rotating cylinder 27. Since the two ends of the connecting rod 30 are rotatably connected to the end of the driving rod 29 and the end of the ring 28, and the ring 28 is sleeved on the outside of the discharge pipe 4, the discharge pipe 4 is driven to reciprocate on the bracket. At the same time, the sliding connection between the L-shaped block 14 and the L-shaped groove 15 plays a positioning role for the discharge pipe 4 and the lower pipe 6 sliding between the support plate 7 and the support 3, thereby ensuring the stability of the overall structure.
