Description

Technical Field

[0001] The utility model relates to the technical field of cement production detection, in particular to a mortar test mold. 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] A mortar test mold is a mold used to prepare cement mortar specimens. In cement engineering, in order to test the performance of cement mortar, it is often necessary to prepare standardized specimens for experiments. The molds used to prepare these cement mortar specimens are called mortar test molds. These molds are usually made of metal or plastic and have specific sizes and shapes to ensure that the prepared cement mortar specimens meet standard specifications.

Therefore, they cannot be understood as limitations on the present invention.

[0024] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0025] Since the existing mortar test mold is usually an integral structure and due to the viscosity of cement mortar, the test mold and the sample are sometimes stuck together, making it difficult to remove the sample and affecting the subsequent cleaning of the test mold, thereby affecting the reuse of the test mold.

[0026] In order to solve the above technical problems, Figures 1 to 3 As shown, a mortar test mold is mainly composed of a base 1, an upper mold 2 and a locking member 3. Specifically, the base 1 has a base body 1-1. In order to facilitate the placement of the upper mold 2 and the sample, the base body 1-1 is flat and its size is adapted to the size of the upper mold 2. In order to fix the upper mold 2, the base body 1-1 in this embodiment has a stopper 1-2 at one end, and a connecting seat 1-3 that also plays a shielding role at the other end of the base body 1-1. In order to ensure the stability of the upper mold 2 during the placement process, the stopper 1-2, the connecting seat 1-3 and the base body 1-1 are all set at an angle. In this embodiment, the stopper 1-2, the connecting seat 1-3 and the base body 1-1 are vertically arranged. On the one hand, the structural strength of the base 1 itself can be ensured. On the other hand, the vertically arranged stopper 1-2 and the connecting seat 1-3 can fit the side of the upper mold 2 to ensure the stability of the upper mold 2, thereby ensuring the stability of the sample placed in the upper mold 2 and the quality of the sample. In order to make the base 1 adapt to upper molds 2 of different models and sizes, in this embodiment, a connecting hole 1-4 is opened in the connecting seat 1-3, the upper mold 2 is installed on the base body 1-1, and the upper mold 2 is fixed between the block 1-2 and the connecting seat 1-3 by inserting the locking member 3 in the connecting hole 1-4, and finally one end of the locking member 3 is abutted against the upper mold 2 to fix the position of the upper mold 2. The above setting method can realize the detachable installation between the base 1 and the upper mold 2 on the one hand, and the base 2 can adapt to upper molds 2 of different models and sizes on the other hand, so that it has a wider range of applications and reduces the use cost of the enterprise.

[0027] Due to the viscosity of cement mortar, the test mold and the sample sometimes stick together, making it difficult to remove the sample. In this embodiment, in order to further facilitate the removal of the sample, the test mold 2 is designed as a split structure. Specifically, the upper mold 2 is mainly composed of a front baffle 2-1, a rear baffle 2-2 and two side baffles 2-3. The front baffle 2-1 is arranged opposite to the rear baffle 2-2 and is surrounded by the two side baffles 2-3 to form a cubic structure, i.e., a receiving cavity for placing the sample. In order to achieve rapid disassembly and assembly, in this embodiment, both the front baffle 2-1 and the rear baffle 2-2 are provided with an installation groove 2-5. The cross-sectional width of the installation groove 2-5 is adapted to the thickness of the side baffle 2-3. The side baffle 2-3 is embedded in the installation groove 2-5.

[0028] In order to facilitate the preparation of multiple samples, a middle partition 2-4 is provided between the two side baffles 2-3. Similarly, the front baffle 2-1 and the rear baffle 2-2 corresponding to the position of the middle partition 2-4 are provided with mounting grooves 2-5, and the middle partition 2-4 is embedded in the mounting grooves 2-5. The middle partition 2-4 can divide the test mold into multiple parts, so that each part can be filled with cement mortar separately, which is convenient for preparing multiple samples. The middle partition 2-4 can also effectively prevent the test mold from deforming when filling cement mortar, ensuring that the size and shape of the prepared samples are accurate. The setting of the middle partition 2-4 can also prepare multiple samples at one time, which improves the efficiency of sample preparation and saves time and cost. In actual use, the position of the middle partition 2-4 can be adjusted according to the size and shape of the sample.

[0029] In order to prevent the upper mold 2 from sliding to the side during use, thereby affecting the quality of the sample. A positioning hole 1-5 is opened on the base 1 located on the side of the upper mold 2, and a positioning member 4 is inserted into the positioning hole 1-5. The position of the upper mold 2 is fixed by three-sided positioning, and then the position of the sample is fixed to ensure the quality of the sample. The three-sided positioning is positioning by the positioning member 4, the block 1-2 and the locking member 3. The positioning member 4 is a positioning pin, which can provide precise positioning to ensure that the positional relationship between the base body 1-1 and the upper mold 2 is accurate, which is conducive to assembly and fixation. The positioning pin is usually made of high-strength material, which can provide reliable connection and fixing to ensure structural stability. The positioning pin is detachable, which is convenient for future maintenance and replacement. Through the use of positioning pins, assembly can be carried out quickly and accurately, improving production efficiency and reducing assembly time.

[0030] The above-mentioned block 1-2 can be one or more, and its main purpose is to realize the positioning of one end of the upper mold 2. In this embodiment, there are two above-mentioned blocks 1-2, and the two above-mentioned blocks 1-2 are arranged at a distance. The appropriate spacing can promote air circulation, which is beneficial to heat dissipation and ventilation, and thus improves the rate of sample molding. If there is one above-mentioned block 1-2, the length must also be similar to the total length of the above-mentioned two blocks 1-2 to ensure the stability of the end of the upper mold 2. In this embodiment, the two above-mentioned blocks 1-2 are arranged at a distance and close to the side of the above-mentioned base body 1-1, which can ensure that the weight of the base 1 itself can be reduced while supporting the end of the upper mold 2, so as to facilitate the transportation of the mobile base 1.

[0031] The base 1 is integrally formed, that is, the base body 1-1, the stopper 1-2 and the connecting seat 1-3 are integrally formed. The integral forming can ensure that the connection between the base body 1-1, the stopper 1-2 and the connecting seat 1-3 is more firm, and improve the overall strength and stability; the integral forming can also ensure that the size and position of the base body 1-1, the stopper 1-2 and the connecting seat 1-3 are accurate, avoiding problems caused by assembly errors. The integral forming can reduce the manufacturing and assembly processes of parts, improve production efficiency and reduce production costs. The integral forming can eliminate the seams between components, making the product appearance more beautiful and improving the overall texture.

[0032] The locking member 3 is a locking bolt, and the connecting holes 1-4 are threaded holes. The threaded holes can be closely matched with the locking bolts to provide a firm connection, thereby ensuring the safety and stability between the connecting seat 1-3 and the locking member 3. The threaded connection is convenient for disassembly and replacement, which is beneficial for future maintenance and repair work, and is convenient for disassembly and assembly of the upper mold 2, reducing the difficulty of disassembly and assembly. The threaded holes can be adjusted as needed, so that the position and angle of the locking bolts can be flexibly changed according to the position of the upper mold 2, thereby improving applicability and adjustability.

[0033] Due to the viscosity of cement mortar, the test mold and the sample sometimes stick together, making it difficult to remove the sample. The mortar test mold in this embodiment, that is, the base 1 and the upper mold 2 are usually made of metal or plastic. The metal test mold is usually made of cast iron or steel, has high wear resistance and stability, and is suitable for long-term use. The plastic test mold is usually made of polymer material, has good anti-sticking and formability, and is suitable for one-time or short-term use. The user can choose a suitable test mold according to needs.

[0034] A mortar test mold in the present embodiment has an ingenious structure. The base and the upper mold are detachably arranged. When taking samples, it is only necessary to separate the base from the upper mold and then tap the upper mold to separate the sample from the upper mold. This facilitates the removal of the sample and ensures the integrity of the sample. At the same time, it is convenient to clean the test mold later, thereby ensuring the cleanliness of the test mold and enhancing the user experience. This is conducive to the promotion and application of the above-mentioned mortar test mold in the field of cement production and testing technology.
