Description

Technical Field

[0001] The utility model relates to the technical field of cement production detection, in particular to a bottom mold rotation positioning mechanism. Background Art

[0002] Cement is a common building material that is made from limestone, clay and other materials that have been calcined and ground. Cement is widely used in the construction industry to make concrete, mortar and other building structures. It has good adhesion and durability, and can solidify and harden to form a strong structure. The main components of cement are limestone and clay, which are calcined at high temperatures to form clinker. The clinker is ground into a fine powder together with an appropriate amount of gypsum to form the final cement product. There are many varieties of cement, the most common ones are Portland cement, sulphoaluminate cement and ordinary Portland cement. Cement is widely used in construction. It can be used to build various projects such as houses, bridges, roads, tunnels, etc. Cement can be mixed with sand, gravel and water to form concrete, which is used to cast structures such as foundations, columns, beams and floor slabs. Cement can also be used with mortar for bricklaying, plastering and repair work.

[0003] Cement raw meal is a material that is ground to a certain fineness by mixing lime raw materials, clay raw materials and a small amount of correction raw materials (sometimes mineralizers, crystal seeds, etc. are added, and coal is added during vertical kiln production) in proportion. In the cement production process, it is necessary to control the products of each link to ensure that the quality of the final cement product meets the requirements. The higher the decomposition rate of cement raw meal, the higher the heat exchange efficiency of the kiln tail preheater and the better the working condition of the decomposition furnace. Therefore, the decomposition rate of raw meal entering the kiln is an important indicator for evaluating the working effect of the pre-decomposition furnace system, and it is also an important parameter for production control. Therefore, obtaining hot raw meal is the primary link of analysis and control.

[0004] The mortar test mold is a mold used to prepare cement mortar samples. In cement engineering, in order to test the performance of cement mortar, it is often necessary to prepare standardized samples for experiments.

[0028] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0029] In the prior art, the direction of the test mold base is usually adjusted by lifting tools such as trusses. Manual cooperation is usually required in this process, which makes it difficult to achieve automated mold removal, affecting the user experience.

[0030] In order to solve the above technical problems, Figures 1 to 5 As shown, a bottom mold rotation positioning mechanism is mainly used for the test mold base 6 of the rotating mortar test mold, so as to automatically clean the test mold base 6 later. The bottom mold rotation positioning mechanism is mainly composed of a rotating cylinder mounting seat 1, a rotating cylinder 2, a bottom mold fixing plate 3 and a speed control valve 4. It has a simple structure and is easy to install and operate. In order to ensure the stability of the rotating cylinder 2 during operation, the rotating cylinder 2 is installed on the rotating cylinder mounting seat 1. In order to make the rotating cylinder mounting seat 1 replaceable, that is, the height of the rotating cylinder 2 can be adjusted, the rotating cylinder 2 can be detachably installed on the rotating cylinder mounting seat 1. Specifically, a mounting hole can be opened in the rotating cylinder mounting seat 1, and a mounting hole is also set at the corresponding position of the rotating cylinder 2. The fixed connection between the rotating cylinder mounting seat 1 and the rotating cylinder 2 is realized by inserting a locking bolt and other connecting parts in the mounting hole. In order to realize the rotation of the bottom mold fixing plate 3 and further realize the rotation of the test mold base 6 placed on the bottom mold fixing plate 3, the bottom mold fixing plate 3 is installed at the output end of the rotating cylinder 2. The speed control valve 4 is installed on the rotating cylinder 2 and is used to control the speed of the rotating cylinder 2. The speed control valve 4 in this embodiment is an elbow type speed control valve, which has a small, clever and compact structure, is easy to install, and reduces the occupation of space.

[0031] The above-mentioned rotating cylinder 2 includes a cylinder body 2-1, and a cylinder connecting plate 2-2 is installed at the output end of the above-mentioned cylinder body 2-1. In this embodiment, the output end of the above-mentioned cylinder body 2-1 is at the top of the cylinder body 2-1, that is, the cylinder connecting plate 2-2 is installed on the top of the cylinder body 2-1, and a cylinder connecting hole 2-3 is opened on the above-mentioned cylinder connecting plate 2-2, and the above-mentioned bottom mold fixing plate 3 is provided with a fixing plate connecting part 3-1, and a fixing plate connecting hole 3-2 is opened at the above-mentioned fixing plate connecting part 3-1. In order to ensure the assembly effect, the above-mentioned fixing plate connecting hole 3-2 is arranged corresponding to the above-mentioned cylinder connecting hole 2-3, and locking bolts and other connecting parts are passed through the above-mentioned fixing plate connecting hole 3-2 and the above-mentioned cylinder connecting hole 2-3 to realize the connection between the above-mentioned cylinder connecting plate 2-2 and the above-mentioned bottom mold fixing plate 3. In order to ensure the connection effect and reduce the probability of separation between the two, the fixing plate connection holes 3-2 and the cylinder body connection holes 2-3 are both multiple, and the multiple fixing plate connection holes 3-2 are evenly distributed along the circumference of the fixing plate connection portion 3-1, and the multiple cylinder body connection holes 2-3 are evenly distributed along the circumference of the cylinder body connection plate 2-2, which ensures the connection reliability while reducing the probability of the bottom mold fixing plate 3 tilting, thereby ensuring the stability of the test mold base 6 placed thereon. In order to prevent the locking bolt from protruding from the surface of the bottom mold fixing plate 3 and affecting the test mold base 6, the fixing plate connection holes 3-2 in this embodiment are countersunk holes, more specifically countersunk screw holes, so that the locking bolts can be locked in the countersunk screw holes.

[0032] In order to adapt to the output end of the rotating cylinder 2, the cylinder body connecting plate 2-2 and the fixed plate connecting portion 3-1 in this embodiment are both arranged in a circular shape, and the fixed plate connecting portion 3-1 is located in the middle position of the bottom mold fixing plate 3 to ensure the stability of the bottom mold fixing plate 3 during the driving process of the rotating cylinder 2.

[0033] In order to reduce the weight of the bottom mold fixing plate 3 itself and ensure the structural strength of the bottom mold fixing plate 3 itself, a weight-reducing groove 3-3 is provided on the bottom mold fixing plate 3. In this embodiment, there are four weight-reducing grooves 3-3, which are arranged at intervals along the circumference of the fixing plate connecting portion 3-1, and three surfaces of the weight-reducing groove 3-3 are planes and one surface is a curved surface, so as to match the shapes of the fixing plate connecting portion 3-1 and the bottom mold fixing plate 3.

[0034] In this embodiment, by providing positioning pins 5 at the four corners of the bottom mold fixing plate 3, the test mold base 6 can be prevented from falling during the rotation process, thereby ensuring the service life of the test mold base 6. Specifically, positioning pin holes 3-4 are respectively provided at the four corners of the bottom mold fixing plate 3, and the positioning pins 5 can be directly inserted into the positioning pin holes 3-4.

[0035] The rotary cylinder 2 in this embodiment is a low-speed rotary cylinder, which can provide more precise rotation control and is suitable for applications that require fine positioning and low-speed rotation, thereby ensuring that the test mold base 6 can be rotated into place to meet the needs of users. Compared with high-speed rotary cylinders, low-speed rotary cylinders usually require less energy to achieve the same rotation effect, which helps to save energy. Slow-speed rotary cylinders are usually more stable when running at low speeds, reducing mechanical vibration and unnecessary friction, which helps to improve system stability. Slow-speed rotary cylinders usually produce less noise, which is conducive to reducing the noise level of the working environment.

[0036] A bottom mold rotation and positioning mechanism in the present embodiment has a simple and ingenious structure. By setting a rotating cylinder 2 and a bottom mold fixing plate 3, the test mold base 6 can be moved to the bottom mold fixing plate 3 through lifting tools such as trusses, and then the bottom mold fixing plate 3 is driven by the rotating cylinder 2 to achieve the direction of the test mold base 6. It is ensured that the direction of rotation meets the requirements, reduces the difficulty of operation, enhances the user experience, and is conducive to the promotion and application of the above-mentioned bottom mold rotation and positioning mechanism in the market.
