Description

Technical Field

[0001] This utility model relates to a testing device for high and low temperature resistant expanded perlite, belonging to the field of expanded perlite processing technology. Background Technology

[0002] Expanded perlite is a lightweight, porous mineral material, typically produced from natural volcanic perlite through high-temperature expansion. Its unique porous structure endows it with excellent thermal insulation, sound absorption, and seismic resistance properties, making it widely used in construction, agriculture, and industry. The production process involves heating natural perlite ore to high temperatures (approximately 800-1000℃), causing it to expand and form foam-like particles. After cooling, a material with extremely low density and good mechanical properties is obtained. Due to its excellent physical properties, expanded perlite is widely used in thermal insulation, soil improvement, and filtration. However, under extreme temperature conditions (such as high or low temperatures), the performance of expanded perlite may be affected. Therefore, research and testing of its high and low temperature resistance are particularly important and represent a key technology for its further application and optimization.

[0003] Authorization announcement number (CN215677820U) discloses a testing device for expanded perlite, including a base plate, a pair of swing arms on both sides of the base plate, a first connecting shaft above the base plate, and a second connecting shaft below the base plate. The second connecting shaft is fixedly connected to the bottom end of the pair of swing arms, and the first connecting shaft is fixedly connected to the pair of swing arms. The first connecting shaft is rotatably connected to the upper end surface of the base plate through a bearing seat. A placement frame is fixed to the top of the pair of swing arms, and several slots are recessed in the top of the placement frame. Measuring tubes are inserted into the slots, and a load-bearing component is detachably connected to the measuring tubes. A cylinder is hinged to the bottom surface of the base plate, and the output end of the cylinder is hinged to the second connecting shaft. This testing device simulates the compression and vibration during transportation by swinging back and forth between the measuring tubes containing expanded perlite and the load-bearing component, thereby testing the strength of expanded perlite by measuring the changes in its strength. It has a simple structure and better effect, and multiple measuring tubes can swing together, improving efficiency.

[0004] In summary, the aforementioned testing device for expanded perlite lacks performance testing under high and low temperature environments, potentially leading to insufficient assessment of its stability and practical application performance at extreme temperatures. Expanded perlite may experience changes in its expansion rate, pore structure damage, or thermal conductivity in high or low temperature environments, all of which affect its thermal insulation, heat preservation, and compressive strength. If the testing device cannot simulate alternating high and low temperature changes, it may be unable to accurately assess its long-term performance in construction, insulation, agriculture, and other fields, thus impacting the design optimization and application scope of expanded perlite. The lack of high and low temperature testing may also lead to the risk of performance degradation or failure in practical applications, failing to ensure the material's reliability under extreme environments.

[0005] Therefore, a testing device for high and low temperature resistant expanded perlite is proposed. Utility Model Content

[0006] In view of this, the present invention provides a testing device for high and low temperature resistant expanded perlite to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is as follows: A testing device for high and low temperature resistant expandable perlite includes a base, and a temperature regulating component is provided on the top of the base. The temperature regulating component includes a drive gear, which is movably connected to the top of the base through a rotating shaft. The surface of the drive gear is connected to driven gears through tooth meshing, and there are four driven gears, which are equidistantly distributed around the drive gear.

[0008] More preferably, an X-shaped plate is movably connected to the top of the driving gear, and a connecting rod is fixedly installed on the top of the driven gear. The connecting rod passes through the perimeter of the X-shaped plate and extends to the top of the X-shaped plate.

[0009] More preferably, heating rods are fixedly installed on both the front and rear sides of the connecting rod, and cooling rods are fixedly installed on both the left and right sides of the connecting rod.

[0010] More preferably, a bearing is movably connected to the top of the X-shaped plate, and a tank is movably connected to the top of the bearing, with the tank located inside the heating rod and the X-shaped plate.

[0011] More preferably, a tank is fixedly installed on the top of the base, and the output end of the tank is fixedly connected to the drive gear.

[0012] More preferably, a mounting plate is fixedly installed on the top of the base, a cylinder is fixedly installed on the top of the mounting plate, and a pressure hammer is fixedly connected to the output end of the cylinder.

[0013] More preferably, table legs are fixedly installed around the bottom of the base, and rubber pads are fixedly installed on the bottom of the table legs.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model, by starting the tank, drives the output end of the tank to rotate the drive gear. At the same time, the drive gear rotates and drives the driven gear on the surface to rotate through the meshing of the teeth. The drive gear also drives the X-shaped plate on the top to rotate. At the same time, the driven gear rotates and drives the heating rod and cooling rod on the top to rotate through the connecting rod. At the same time, the rotation of the X-shaped plate drives the heating rod and cooling rod to rotate around the tank. This can realistically simulate the performance changes of expanded perlite under extreme temperature conditions, thereby more accurately evaluating its stability and reliability in practical applications.

[0016] II. This utility model uses a starting cylinder, which drives a pressure hammer to move up and down through its output end. The pressure hammer tests the hardness of the material inside the tank, which can effectively evaluate the mechanical strength and compressive strength of expanded perlite under different environments, and help to understand whether it can withstand external pressure and impact in practical applications.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-6 As shown, this utility model embodiment provides a testing device for high and low temperature resistant expanded perlite, including a base 1, a temperature regulating component 7 is provided on the top of the base 1, the temperature regulating component 7 includes a drive gear 701, the drive gear 701 is movably connected to the top of the base 1 through a rotating shaft, the surface of the drive gear 701 is connected to a driven gear 702 through tooth meshing, and there are four driven gears 702, which are equidistantly distributed around the drive gear 701.

[0030] By activating the tank 707, the output end of the tank 707 drives the drive gear 701 to rotate. As the drive gear 701 rotates, it drives the driven gear 702 on the surface to rotate through the meshing of the teeth. The drive gear 701 also drives the X-shaped plate 703 on the top to rotate. As the driven gear 702 rotates, it drives the heating rod 705 and cooling rod 706 on the top to rotate through the connecting rod 708. As the X-shaped plate 703 rotates, it drives the heating rod 705 and cooling rod 706 to rotate around the tank 707. This can realistically simulate the performance changes of expanded perlite under extreme temperature conditions, thereby more accurately evaluating its stability and reliability in practical applications.

[0031] Example 2

[0032] like Figure 1-6As shown, in one embodiment, an X-shaped plate 703 is movably connected to the top of the driving gear 701, a connecting rod 708 is fixedly installed on the top of the driven gear 702, the connecting rod 708 passes through the four sides of the X-shaped plate 703 and extends to the top of the X-shaped plate 703, heating rods 705 are fixedly installed on both the front and rear sides of the connecting rod 708, and cooling rods 706 are fixedly installed on both the left and right sides of the connecting rod 708. A bearing 704 is movably connected to the top of the X-shaped plate 703, and a tank 707 is movably connected to the top of the bearing 704. The tank 707 is located inside the heating rods 705 and the X-shaped plate 703. The tank 707 is fixedly installed on the top of the base 1, and the output end of the tank 707 is fixedly connected to the driving gear 701. An mounting plate 4 is fixedly installed on the top of the base 1, and a cylinder 5 is fixedly installed on the top of the mounting plate 4. A pressure hammer 6 is fixedly connected to the output end of the cylinder 5. Table legs 2 are fixedly installed around the bottom of the base 1, and rubber pads 3 are fixedly installed on the bottom of the table legs 2.

[0033] By activating cylinder 5, cylinder 5 drives the pressure hammer 6 to move up and down through its output end. The pressure hammer 6 tests the hardness of the material inside tank 707, which can effectively evaluate the mechanical strength and compressive strength of expanded perlite under different environments, and help to understand whether it can withstand external pressure and impact in practical applications.

[0034] In operation, this invention works as follows: First, the expanded perlite to be tested is placed into the tank 707. Upon starting the tank 707, the output end of the tank 707 drives the drive gear 701 to rotate. Simultaneously, the drive gear 701, through tooth meshing, drives the driven gear 702 on the surface to rotate. The drive gear 701 also simultaneously drives the X-shaped plate 703 at the top to rotate. While the driven gear 702 rotates, it drives the heating rod 705 and cooling rod 706 at the top to rotate via the connecting rod 708. The rotation of the X-shaped plate 703, in turn, causes the heating rod 705 and cooling rod 706 to rotate circumferentially around the tank 707. This effectively simulates the performance changes of expanded perlite under extreme temperature conditions, thereby more accurately evaluating its properties. In practical applications, the stability and reliability of expanded perlite are assessed by activating tank 707. The output of tank 707 drives the drive gear 701 to rotate. Simultaneously, the drive gear 701, through tooth meshing, drives the driven gear 702 on the surface to rotate. The drive gear 701 also simultaneously drives the X-shaped plate 703 on top to rotate. The driven gear 702, while rotating, drives the heating rod 705 and cooling rod 706 on top to rotate via connecting rod 708. Finally, the rotation of the X-shaped plate 703 causes the heating rod 705 and cooling rod 706 to rotate around tank 707 in a circular motion. This realistically simulates the performance changes of expanded perlite under extreme temperature conditions, thus more accurately evaluating its stability and reliability in practical applications.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
