Description

Technical Field

[0001] This utility model belongs to the field of cement testing technology, and specifically relates to a rapid testing device for low-alkali cement. Background Technology

[0002] Low-alkali cement, by reducing the alkali content in the cement, can effectively reduce the risk of alkali-aggregate reaction in the active aggregates of concrete, thereby improving the strength of the concrete.

[0003] Currently, Chinese utility model patent CN221100743U discloses a device for detecting the alkali content of low-alkali cement. This device mainly reduces the possibility of white smoke mixing into the air by adjusting the rotation of the smoke extraction pipe to bring it closer to the smoke outlet. However, this method of extracting white smoke only increases the amount of white smoke extracted and cannot completely draw the white smoke into the purification device. Some white smoke will still mix into the air and cause pollution, resulting in poor extraction efficiency. Furthermore, the smoke extraction pipe lacks internal protection, which not only allows white smoke to be drawn in but also easily draws in cement dust and other impurities, causing blockages and affecting normal use. Utility Model Content

[0004] The purpose of this invention is to provide a rapid testing device for low-alkali cement, which has the advantages of improving the efficiency of white smoke extraction, avoiding omissions, and protecting the smoke extraction pipe to prevent cement dust and other impurities from entering the interior.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a low-alkali cement rapid testing device, including a workbench, a bracket bolted to the top of the workbench, a flue gas purification device bolted to the top of the bracket, a cement testing instrument body bolted to the workbench and the bracket, a smoke outlet opened at the top of the cement testing instrument body, a motor bolted to one side of the top of the bracket, a first bevel gear bolted to the output end of the motor, a threaded tube rotatably connected through the inside of the bracket, a second bevel gear meshing with the first bevel gear fixedly sleeved on the top surface of the threaded tube, a threaded cylinder threadedly sleeved on the bottom surface of the threaded tube, an isolation cover welded to the bottom of the threaded cylinder, a through groove communicating with the threaded tube opened inside the isolation cover, and a sealing plug slidably inserted into the bottom of the threaded tube adhered to the top of the isolation cover.

[0006] Using the above technical solution, the surface of the smoke outlet can be covered by the downward sliding of the isolation cover, thus preventing the white smoke from mixing with the outside air, ensuring the extraction effect of white smoke, and avoiding leakage. Simultaneously, when the isolation cover is reset, the threaded pipe can be sealed with a sealing plug to prevent backflow of white smoke. The spring force drives the sliding frame to slide downward, thus pressing the filter screen tightly against the top of the smoke outlet to filter the emitted white smoke. This prevents cement dust and other impurities from entering the interior and causing blockage of the smoke extraction pipe, ensuring white smoke extraction efficiency and improving practicality.

[0007] The present invention is further configured such that: a sliding frame is slidably connected inside the isolation cover, a filter screen for use with the smoke outlet is bolted inside the sliding frame, and springs bolted to the isolation cover are fixedly connected to both sides of the top of the sliding frame.

[0008] The above technical solution filters out white smoke, preventing cement dust and other impurities from entering the interior and causing blockage inside the smoke extraction pipe.

[0009] The present invention is further configured such that: one end of the flue gas purification device is bolted to a connecting pipe that is rotatably connected to the top of the threaded pipe, and sealing rings that are slidably connected to each other are bonded between the threaded pipe and the connecting pipe.

[0010] By adopting the above technical solution, the threaded pipe can rotate on the surface of the connecting pipe while maintaining continuous transmission of white smoke, thus improving the sealing performance of the connection.

[0011] The present invention is further configured such that: sliding rods are welded to both sides of the bottom of the bracket, and limiting sleeves that are slidably connected to the sliding rods are bolted to both sides of the top of the isolation cover.

[0012] The above technical solution is used to limit the sliding of the isolation cover and improve the stability of its vertical sliding.

[0013] The present invention is further configured such that a sealing gasket, which is used in conjunction with the cement testing instrument body, is adhered to the bottom of the isolation cover.

[0014] By adopting the above technical solution, the sealing performance of the isolation cover after it is placed on top of the cement detector body is improved, preventing white smoke from spreading outward.

[0015] The present invention is further configured such that: a water tank is bolted to one side of the top of the workbench, and a water outlet pipe is bolted to one side of the top of the water tank.

[0016] The above technical solution facilitates the rapid addition of water to cement for testing. It also allows for convenient handwashing after the testing is completed.

[0017] The present invention is further configured such that lighting lamps are bolted to both sides of the bottom of the bracket.

[0018] The above technical solution is used to provide supplemental lighting, which facilitates cement testing operations when light is insufficient.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By sliding the isolation cover downwards, the surface of the smoke outlet can be covered, thus preventing the white smoke from mixing with the outside air, ensuring the effectiveness of white smoke extraction, and avoiding leakage. At the same time, when the isolation cover is reset, the threaded pipe can be sealed by inserting a sealing plug to prevent the white smoke from flowing back;

[0021] 2. The spring force causes the sliding frame to slide downwards, thus pressing the filter screen tightly against the top of the smoke outlet to filter the emitted white smoke. This prevents cement dust and other impurities from entering the interior and causing blockages in the smoke extraction pipe, ensuring efficient white smoke extraction and improving practicality.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A rapid testing device for low-alkali cement includes a workbench 1, a support 2 bolted to the top of the workbench 1, and a flue gas purification device 5 bolted to the top of the support 2. The flue gas purification device 5 is an SDE-1200 plasma flue gas purifier manufactured by Shangyu Smart Environmental Protection Technology Co., Ltd. A cement testing instrument body 3, bolted to the workbench 1, is located between the workbench 1 and the support 2. The cement testing instrument body 3 is an SSWY-910 rapid concrete alkali content tester manufactured by Shanghai Shengshi Huike Testing Equipment Co., Ltd. The top of the cement testing instrument body 3... The bracket 2 has a smoke outlet 4. A motor 6 is bolted to one side of the top of the bracket 2. A first bevel gear 7 is bolted to the output end of the motor 6. A threaded tube 9 is rotatably connected through the inside of the bracket 2. A second bevel gear 8, which meshes with the first bevel gear 7, is fixedly sleeved on the top surface of the threaded tube 9. A threaded cylinder 11 is threadedly sleeved on the bottom surface of the threaded tube 9. An isolation cover 10 is welded to the bottom of the threaded cylinder 11. The isolation cover 10 has a through groove 12 communicating with the threaded tube 9 inside. A sealing plug 13, which slides into the bottom of the threaded tube 9, is glued to the top of the isolation cover 10. By sliding the isolation cover 10 downwards, the surface of the smoke outlet 4 can be covered, thereby preventing the white smoke from mixing with the outside air, ensuring the extraction effect of the white smoke, and avoiding leakage. At the same time, when the isolation cover 10 is reset, the sealing plug 13 can also be inserted and sealed to the threaded tube 9 to prevent the white smoke from flowing back.

[0030] refer to Figure 1 , Figure 4 One end of the flue gas purification device 5 is bolted to a connecting pipe 17 that rotatably communicates with the top of the threaded pipe 9. Sealing rings 18 are bonded between the threaded pipe 9 and the connecting pipe 17, allowing the threaded pipe 9 to rotate on the surface of the connecting pipe 17 while maintaining continuous flow of white smoke, thus improving the sealing at the connection.

[0031] refer to Figure 2 , Figure 4 Sliding rods 19 are welded to both sides of the bottom of the bracket 2, and limiting sleeves 20, which are slidably connected to the sliding rods 19, are bolted to both sides of the top of the isolation cover 10. These are used to limit the sliding of the isolation cover 10 and improve the stability of its vertical sliding.

[0032] refer to Figure 2 , Figure 4 The bottom of the isolation cover 10 is bonded with a sealing gasket 21 that works in conjunction with the cement detector body 3. This improves the sealing performance of the isolation cover 10 after it is placed on top of the cement detector body 3, preventing white smoke from spreading outwards.

[0033] Brief description of the operation: By turning on the motor 6, the first bevel gear 7 rotates and meshes with the second bevel gear 8, causing the second bevel gear 8 to drive the threaded tube 9 to rotate inside the bracket 2. Then, the second bevel gear 8 engages with the threaded cylinder 11, causing the isolation cover 10 to slide up and down on the top of the cement detector body 3 under the limitation of the sliding rod 19 and the limiting sleeve 20. When the isolation cover 10 slides down, it can cover the smoke outlet 4, isolating the surrounding air. Thus, after the white smoke comes out from inside the smoke outlet 4, it can be extracted through the through groove 12 and the threaded tube 9 and enter the flue gas purification device 5 for purification, preventing the white smoke from mixing with the air. At the same time, after the white smoke is extracted, when the motor 6 drives the isolation cover 10 to slide down and reset, the sealing plug 13 can also slide down to seal the bottom of the threaded tube 9, thereby preventing the white smoke from flowing back into the air and causing pollution.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 , Figure 4 A rapid testing device for low-alkali cement includes a sliding frame 14 slidably connected inside an isolation cover 10. A filter screen 16, which works in conjunction with a smoke outlet 4, is bolted inside the sliding frame 14. Springs 15, also bolted to the isolation cover 10, are fixedly connected to both sides of the top of the sliding frame 14. The spring force of the springs 15 causes the sliding frame 14 to slide downwards, thus pressing the filter screen 16 tightly against the top of the smoke outlet 4 to filter the emitted white smoke. This prevents cement dust and other impurities from entering the interior and causing blockage of the smoke extraction pipe, ensuring efficient white smoke extraction and improving practicality.

[0036] refer to Figure 1 , Figure 2 A water tank 22 is bolted to one side of the top of the workbench 1, and a water outlet pipe 23 is bolted to one side of the top of the water tank 22. This facilitates the rapid addition of water to the cement for testing. It also makes it convenient to wash hands after testing.

[0037] refer to Figure 2 Lighting lamps 24 are bolted to both sides of the bottom of the bracket 2 to provide supplemental lighting, facilitating cement testing operations in low-light conditions.

[0038] Brief description of the operation: When the motor 6 drives the isolation cover 10 to move downwards and fit into the cement detector body 3, the isolation cover 10 can cover the top of the smoke outlet 4. At this time, the filter screen 16 can be driven by the elastic force of the spring 15 to slide the sliding frame 14 downwards, thereby pressing the filter screen 16 tightly against the top of the smoke outlet 4, filtering the white smoke and preventing cement dust and other impurities from entering the interior.
