Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a cement grinding aid measuring device. Background Art

[0002] During the cement production process, grinding aids need to be added to improve the grinding effect. Grinding aids are added at a fixed volume per minute, and are automatically added by an automatic constant speed quantitative addition mechanism. However, as the working time increases or other inducements occur, the amount added per minute will change, thus affecting the efficiency of cement production. In order to ensure that the amount added per minute is constant, the staff needs to regularly measure the amount added per minute. In the prior art, a measuring tool such as a graduated cylinder is placed under the addition head to receive the grinding aid dripping for one minute, and then the scale is read to obtain the amount added per minute. The grinding aid in the measuring tool is then poured into the production line at one time. This method is completely manually operated, time-consuming and labor-intensive, and is prone to causing cement splashing when poured into the cement production line, making the area around the measuring port dirty. Therefore, the utility model provides a cement grinding aid measuring device. Utility Model Content

[0003] The purpose of the utility model is to provide a cement grinding aid measuring device.

[0004] In order to solve the above technical problems, the purpose of this utility model is achieved as follows:

[0007] A vent pipe is provided on the top of the measuring cylinder; a fourth valve is provided on the vent pipe.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme, the measuring cylinder includes a top cover, a middle section and a bottom section; the top cover is detachably connected to the top of the middle section; the middle section is made of a transparent material, and the scale line is provided on the outer wall; the bottom section is connected to the bottom end of the middle section, and the discharge pipe is connected below it.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme, the placement rack includes a top seat, a middle part and a base; the top seat is connected to the top of the middle part, and a hole is opened in the center; the middle part is composed of a number of support rods arranged at intervals; the base is connected to the bottom end of the middle part, and a hole is opened in the center.

[0010] On the basis of the above solution and as a preferred solution of the above solution, the connection between the anti-overflow pipe and the feed pipe is located above the second valve.

[0011] On the basis of the above solution and as a preferred solution of the above solution, the anti-overflow pipe is L-shaped; the third valve is arranged on the section where the anti-overflow pipe is connected to the feed pipe.

[0012] The beneficial effects of the utility model are as follows: when measuring, the utility model first closes the first valve on the discharge pipe, then waits for one minute, and determines whether the dripping rate of the automatic grinding aid adding mechanism meets the demand by observing the amount of grinding aid accumulated in the measuring cylinder. Compared with traditional manual measurement, there is no need for staff to hold the measuring cylinder by hand, which reduces the labor intensity of measurement and saves time and effort. At the same time, after the measurement is completed, it is only necessary to open the first valve to allow the grinding aid in the measuring cylinder to drip into the cement production line from the discharge pipe. Compared with manually pouring the grinding aid in the measuring cylinder into the cement production line, it is more stable and will not cause cement splashing, which will cause the measuring area to become dirty. The number of cleaning times can be reduced, which saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 and Figure 2 As shown, a cement grinding aid measuring device includes a base frame 1, which is fixed to the cement production line and mounted on the grinding aid addition port provided on the cement production line. The base frame 1 has an opening, and a placement frame 2 is provided on the top, and a measuring cylinder 3 is disposed within the placement frame 2.

[0018] The rack 2 is a cylindrical structure, comprising a top seat 21, a middle portion 22, and a base 23. The top seat 21 is connected to the top of the middle portion 22, with a central hole for the measuring cylinder 3 to pass through. The middle portion 22 is composed of several spaced support rods to form a hollow structure, making it easy to view the scale of the internal measuring cylinder 3. The base 23 is connected to the bottom of the middle portion 22, with a central hole to allow the grinding aid in the measuring cylinder 3 to drip downward into the cement production line.

[0019] The measuring cylinder 3 has transparent sidewalls and scale lines 4 on its outer sidewalls. Specifically, the measuring cylinder 3 includes a top cover 31, a middle section 32, and a bottom section 33. The top cover 31 is removably connected to the top of the middle section 32, to which the feed pipe 6 is connected. The middle section 32 is made of a transparent material and has scale lines 4 on its outer wall. The bottom section is connected to the bottom end of the middle section 32, and below it is connected a discharge pipe 5. The discharge pipe 5 extends downward from the central through hole of the base 23 to the cement production line to reduce the height of the grinding aid dripping and reduce the dust and other impurities splashed by the grinding aid dripping.

[0020] Preferably, in order to keep the measuring cylinder 3 located in the placement rack 2 arranged vertically, a stepped structure adapted to the bottom section 33 is provided on the base 23 .

[0021] The discharge pipe 5 is equipped with a first valve 7 to control the flow of grinding aid from the measuring cylinder 3 into the cement production line. The feed pipe 6 is equipped with a second valve 8 to control the flow of grinding aid from the grinding aid addition device to the measuring cylinder 3. The top of the feed pipe 6 is connected to the automatic grinding aid addition device.

[0022] One side of the feed pipe 6 is connected to an overflow prevention pipe 9 equipped with a third valve 10. The bottom of the overflow prevention pipe 9 extends below the opening. This prevents overflow from the measuring cylinder 3. Once the measuring cylinder 3 is full of grinding aid, the grinding aid flows out of the overflow prevention pipe 9 and drips into the cement production line, preventing equipment failure or errors in the amount of grinding aid added due to human error. The third valve 10 controls the opening and closing of the overflow prevention pipe 9.

[0023] Preferably, the connection between overflow prevention pipe 9 and feed pipe 6 is located above second valve 8. Overflow prevention pipe 9 is L-shaped, and third valve 10 is located at the section where overflow prevention pipe 9 and feed pipe 6 meet. One section of the L-shaped overflow prevention pipe 9 is horizontal and connected to feed pipe 6, while the other section is vertical and extends downward to the cement production line. Third valve 10 is located on the horizontal section.

[0024] A vent pipe 11 is provided on the top of the measuring cylinder 3, and a fourth valve 12 is provided on the vent pipe 11. The vent pipe 11 is used to connect the inside of the measuring cylinder 3 with the outside atmosphere to avoid being blocked and causing the grinding aid to enter.

[0025] Measurement process: Ensure that the second valve 8, third valve 10, and fourth valve 12 remain open, then close the first valve 7 and start timing. When the set time is reached, close the second valve 8. After a period of stagnant time, observe the volume of grinding aid in the measuring tube 3 to determine the amount of grinding aid added per minute. After the measurement is completed, open the first valve 7 and the second valve 8 to maintain the normal flow of grinding aid addition.

[0026] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
