Abstract

This application relates to an integrated steam curing and testing device, belonging to the technical field of cement product production and curing. It includes a housing and a steam generator, with the steam generator located on the back of the housing and a door on the front. This application utilizes a rotary motor. The operation of the rotary motor rotates a drive gear, which, through meshing with a driven gear, drives a rotating rod and a reciprocating screw. This causes a threaded cylinder to move along the reciprocating screw, which in turn causes a connecting block and a U-shaped plate to slide within a moving groove. The sliding of the U-shaped plate causes a U-shaped tube and nozzle to move within the housing, thus achieving uniform steam distribution and effectively improving the steam curing effect. Simultaneously, multiple impedance detection probes can comprehensively cover different areas inside the housing, thereby improving the accuracy and efficiency of the testing.

Description

Technical Field

[0001] This application relates to the production and maintenance of cement products, and in particular to an integrated steam curing and testing device. Background Technology

[0002] Cement products refer to products made using cement, steel bars, or appropriate sand and gravel. Cement curing is an important step, as it optimizes the degree of hydration hardening, strength development, and durability of cement.

[0003] A current patent (publication number: CN111844404A) discloses a sealed steam curing device for cement product production, including a base for support, a box for holding steam and cement products mounted on the base, a sealing door for the box, a water tank for holding liquid water on one side of the box, a lid for conveying steam on the top of the water tank, and a barrier for blocking debris in the middle of the base. This invention utilizes a low-pressure setting, taking advantage of the lower boiling point of water at the same temperature and pressure, to increase steam retention time and improve steam curing effect. The overall sealed design facilitates pressure control and ensures steam accumulation, further enhancing the steam curing effect. The water circulation system reduces waste and saves water resources.

[0004] While the device in the aforementioned comparative document solves the problem that the water after steam liquefaction cannot be recycled, which easily leads to the waste of water resources, the steam ejection structure of the device lacks mobility during the curing process. Long-term curing of the same location coupled with high steam curing temperature can easily lead to a decrease in steam curing efficiency. In order to solve the above problems, an integrated steam curing and testing device is proposed. Utility Model Content

[0005] The purpose of this application is to provide an integrated steam curing and testing device with advantages such as mobility, which solves the problem that the steam ejection structure lacks mobility during the curing process, and the high steam curing temperature during long-term curing of the same location can easily lead to a decrease in steam curing efficiency.

[0006] The steam curing and testing integrated device provided in this application adopts the following technical solution: it includes a box and a steam generator, the steam generator is located on the back of the box, and a door is provided on the front of the box;

[0007] The chamber has a vacuum layer inside. A movable groove is located at the top of the chamber. A fixed shell is fixedly connected to the back of the chamber. A rotating rod is tightly nested inside the movable groove via bearings. A driven gear and a reciprocating screw are fixedly connected to both ends of the rotating rod. The shaft end of the reciprocating screw is rotatably connected to the inside of the movable groove. A threaded cylinder is threaded onto the surface of the reciprocating screw. A connecting block is fixedly connected to the surface of the threaded cylinder. A through hole is located at the bottom of the movable groove. The bottom end of the connecting block slides through the through hole and is fixedly connected to a U-shaped plate. Multiple U-shaped tubes are fixedly connected to the inside of the U-shaped plate. Multiple nozzles are provided on the surface of the U-shaped tubes. A rotary motor is fixedly connected to the side of the fixed shell. The output end of the rotary motor rotates through the side of the fixed shell and is fixedly connected to a drive gear. The driven gear and the drive gear mesh with each other. Multiple impedance detection probes are fixedly connected to the inside of the chamber.

[0008] By adopting the above technical solution, a rotary motor is installed. When the rotary motor runs, the power gear rotates. Through the meshing of the power gear and the driven gear, the rotating rod and the reciprocating screw rotate. This causes the threaded cylinder to move along the reciprocating screw, which in turn causes the connecting block and the U-shaped plate to slide within the moving groove. The sliding of the U-shaped plate causes the U-shaped tube and the nozzle to move within the chamber, thereby achieving uniform steam distribution and effectively improving the steam curing effect. At the same time, multiple impedance detection probes can comprehensively cover different areas inside the chamber, thereby improving the accuracy and efficiency of the detection.

At the same time, the surface of the shrink tube is provided with a folded heat insulation sleeve, which can reduce the energy loss of steam during transmission and prevent steam leakage, thereby improving the sealing and safety of the overall device.

[0012] By adopting the above technical solutions and through special surface treatment of the reciprocating screw and threaded cylinder, their wear resistance and corrosion resistance can be significantly improved. The combination of the AlSiY alloy layer and the WC hard alloy layer enables the reciprocating screw to maintain high hardness and low wear characteristics during long-term operation, thereby extending its service life. At the same time, the Zn-Al alloy layer and Al2O3 ceramic layer inside the threaded cylinder, combined with the PTFE dispersion impregnation treatment, not only enhances the corrosion resistance but also significantly reduces the coefficient of friction, ensuring that the threaded cylinder has higher stability and smoothness in reciprocating motion.

[0013] Preferably, slide rails are fixedly connected to both sides of the bottom of the box, a connecting plate is provided at the bottom of the U-shaped plate, and pulleys are movably connected to both sides of the bottom of the connecting plate by means of pins, and the pulleys are slidably connected in the slide rails;

[0014] By adopting the above technical solution, the smoothness of the U-shaped plate moving inside the box can be improved through the cooperation structure of the slide rail and pulley, while also reducing frictional resistance and ensuring its accuracy and reliability in reciprocating motion.

[0015] Preferably, a collection hopper is provided at the bottom of the box, and a support frame is provided on the inner side of the collection hopper;

[0016] By adopting the above technical solution, the combination of the collection hopper and the support frame can effectively collect condensate or other liquids inside the box, and the stable support of the support frame can prevent the collection hopper from deforming or shifting during use.

[0017] Preferably, a reflux pump is provided on the side of the steam generator, the input end of the reflux pump is located at the bottom of the collection hopper, and the output end of the reflux pump is located inside the steam generator;

[0018] By adopting the above technical solution and setting up a reflux pump, the liquid collected in the collection hopper can be efficiently transferred to the steam generator, thereby realizing the recycling of resources.

[0019] Preferably, an exhaust fan is provided on the top of the housing, and the input end of the exhaust fan is located at the top inside the housing;

[0020] By adopting the above technical solution and installing an exhaust fan, moisture or excess gas inside the box can be effectively removed, thereby maintaining a stable environment inside the box.

[0021] Preferably, the vacuum layer is provided with multiple support blocks, the four corners of the bottom of the box are fixedly connected with support feet, and the side of the box is provided with a control panel;

[0022] By adopting the above technical solution and setting support blocks, the structural strength of the vacuum layer can be effectively enhanced, preventing deformation caused by internal and external pressure differences. At the same time, the design of the support feet can make the box more stable when placed, avoiding shaking or tilting caused by uneven ground.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This integrated steam curing and testing device utilizes a rotary motor. The motor's operation rotates a drive gear, which, through meshing with a driven gear, drives a rotating rod and a reciprocating screw. This causes a threaded cylinder to move along the reciprocating screw, which in turn moves a connecting block and a U-shaped plate within a sliding groove. The sliding of the U-shaped plate causes the U-shaped tube and nozzle to move within the chamber, achieving uniform steam distribution and effectively improving steam curing results. Furthermore, multiple impedance detection probes comprehensively cover different areas within the chamber, thereby... It can improve the accuracy and efficiency of detection. Through special surface treatment of the reciprocating screw and the threaded cylinder, its wear resistance and corrosion resistance can be significantly improved.

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0034] Example 1: An integrated steam curing and testing device, referring to... Figure 1 , Figure 4 and Figure 5 It includes a housing 1 and a steam generator 2. The steam generator 2 is located on the back of the housing 1, and a door 104 is provided on the front of the housing 1.

[0035] The housing 1 has a vacuum layer 101 inside. A movable groove 108 is formed at the top of the housing 1. A fixed shell 1017 is fixedly connected to the back of the housing 1. A rotating rod 1025 is tightly nested inside the movable groove 108 via bearings. A driven gear 1016 and a reciprocating screw 1010 are fixedly connected to both ends of the rotating rod 1025, respectively. The shaft end of the reciprocating screw 1010 is rotatably connected to the inside of the movable groove 108. A threaded cylinder 1011 is threaded onto the surface of the reciprocating screw 1010. A connecting block 1012 is fixedly connected to the surface of the threaded cylinder 1011. A through hole 109 is formed at the bottom of the movable groove 108. The bottom end of the connecting block 1012 slides through the through hole 109 and is fixedly connected to a U-shaped plate 1013. The U-shaped plate 1013 contains... Multiple U-shaped tubes 1014 are fixedly connected to the side, and multiple nozzles 1015 are provided on the surface of the U-shaped tubes 1014. A rotary motor 1018 is fixedly connected to the side of the fixed housing 1017. The output end of the rotary motor 1018 rotates through the side of the fixed housing 1017 and is fixedly connected to a drive gear 1019. The driven gear 1016 meshes with the drive gear 1019. Multiple impedance detection probes 103 are fixedly connected to the inside side of the housing 1. By setting up the rotary motor 1018, the operation of the rotary motor 1018 can make the drive gear 1019 rotate. Through the meshing of the drive gear 1019 and the driven gear 1016, the rotating rod 1025 and the reciprocating screw 1010 can be driven to rotate, thereby making the threaded cylinder rotate. 1011 moves along the reciprocating screw 1010, which drives the connecting block 1012 and the U-shaped plate 1013 to slide within the moving groove 108. The sliding of the U-shaped plate 1013 causes the U-shaped tube 1014 and the nozzle 1015 to move within the housing 1, thus achieving uniform steam distribution and effectively improving steam curing. Simultaneously, multiple impedance detection probes 103 can comprehensively cover different areas inside the housing 1, thereby improving detection accuracy and efficiency. The steam generator 2's steam output end is located on the inner side of the housing 1 and is fixedly connected to a contraction tube 201. The output end of the contraction tube 201 is fixedly connected to the surface of the U-shaped tube 1014. By setting the contraction tube 201, the steam can be generated... The steam generated by generator 2 is centrally transmitted to U-shaped tube 1014 to ensure efficient steam utilization. Simultaneously, a folded insulation sleeve is installed on the surface of the contraction tube 201 to reduce energy loss during steam transmission and prevent steam leakage, thus improving the overall sealing and safety of the device. The surface of the reciprocating screw 1010 is sequentially coated with an AlSiY alloy layer and a WC hard alloy layer. The inner side of the threaded cylinder 1011 is sequentially coated with a Zn-Al alloy layer and an Al2O3 ceramic layer, and impregnated with PTFE dispersion. Through these special surface treatments of the reciprocating screw 1010 and the threaded cylinder 1011, their wear resistance and corrosion resistance are significantly improved. The combination of the AlSiY alloy layer and the WC hard alloy layer...This allows the reciprocating screw 1010 to maintain high hardness and low wear characteristics during long-term operation, thereby extending its service life. Simultaneously, the Zn-Al alloy layer and Al2O3 ceramic layer inside the threaded cylinder 1011, combined with PTFE dispersion impregnation treatment, not only enhance corrosion resistance but also significantly reduce the coefficient of friction, ensuring higher stability and smoothness of the threaded cylinder 1011 during reciprocating motion.

[0036] Please see Figure 3 The bottom of the housing 1 is fixedly connected to slide rails 1020 on both sides. The bottom of the U-shaped plate 1013 is provided with a connecting plate 1021. The bottom of the connecting plate 1021 is movably connected to pulleys 1022 on both sides by pins. The pulleys 1022 are slidably connected in the slide rails 1020. Through the cooperation structure of the slide rails 1020 and the pulleys 1022, the stability of the U-shaped plate 1013 moving inside the housing 1 can be improved, and the frictional resistance can be reduced to ensure its accuracy and reliability in reciprocating motion.

[0037] Please see Figure 4 The bottom of the housing 1 is equipped with a collection hopper 107, and the inside side of the collection hopper 107 is equipped with a support frame 106. Through the cooperative structure of the collection hopper 107 and the support frame 106, the condensate or other liquid inside the housing 1 can be effectively collected. The support frame 106 provides stable support and prevents the collection hopper 107 from deforming or shifting during use. The side of the steam generator 2 is equipped with a return pump 202. The input end of the return pump 202 is located at the bottom of the collection hopper 107, and the output end of the return pump 202 is located inside the steam generator 2. By setting the return pump 202, the liquid collected by the collection hopper 107 can be efficiently transferred to the steam generator 2, thereby realizing the recycling of resources.

[0038] Please see Figure 1 , Figure 2 and Figure 3 A fan 105 is installed on the top of the housing 1, and the input end of the fan 105 is located at the top inside the housing 1. By installing the fan 105, the moisture or excess gas inside the housing 1 can be effectively removed, thereby maintaining the stability of the environment inside the housing 1. Multiple support blocks 102 are installed inside the vacuum layer 101. Support feet 1023 are fixedly connected to the four corners of the bottom of the housing 1. A control panel 1024 is installed on the side of the housing 1. By installing the support blocks 102, the structural strength of the vacuum layer 101 can be effectively enhanced, preventing deformation caused by internal and external pressure differences. At the same time, the design of the support feet 1023 can make the housing 1 more stable when placed, avoiding shaking or tilting caused by uneven ground.

[0039] The implementation principle of this application embodiment is as follows: When in use, people start the device through the control panel 1024, and then the steam generator 2 starts to work and generates high-temperature steam. The generated steam is concentrated and transmitted to the U-shaped tube 1014 through the contraction tube 201, and is evenly distributed into the interior of the box 1 through the nozzle 1015. The rotary motor 1018 starts, driving the power gear 1019, the driven gear 1016, the rotating rod 1025 and the reciprocating screw 1010 to work together, so that the threaded cylinder 1011 moves back and forth along the reciprocating screw 1010, which can push the U-shaped plate 1013 and its connected U-shaped tube 1014 and nozzle 1015 to slide in the box 1, which can ensure that the steam can cover the entire curing area and achieve a uniform steam curing effect.

[0040] During the maintenance period, under the action of the impedance detection probe 103, the status data of different areas inside the box 1 can be monitored in real time, and the information is fed back to the control system to optimize the operating parameters. As the steam condenses, the liquid gradually gathers into the collection hopper 107. Under the stable support of the support frame 106, the condensate is drawn by the return pump 202 and transported back to the steam generator 2, forming a recycling of resources.

[0041] When the exhaust fan 105 is running, it can remove excess moisture or gas, ensuring that the environment inside the enclosure 1 remains stable.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
