Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam curing kilns for cement poles, specifically a steam curing kiln for cement poles. Background Technology
[0002] Steam curing involves placing cement concrete components in a curing chamber and introducing steam to raise the temperature of the concrete, accelerating the hydration and hardening of cement and auxiliary binders, and allowing the concrete to reach its intended strength and hardness more quickly, thereby increasing production turnover and efficiency.
[0003] In the prior art, such as in publication number CN214725155U, a steam curing kiln for cement product production is disclosed. It includes a steam curing kiln body, with two steam valves mounted on its upper surface. A valve-opening base device is externally mounted on the kiln body, comprising a lower base fixedly connected to the lower part of the kiln body. A motor is fixedly connected to the upper part of the middle section of the lower base, and a support frame is fixedly connected to the upper parts of both the left and right sides of the lower base. In this steam curing kiln for cement product production, the movement of a rod sleeve to the right drives a movable rod to the right. The movable rod moves to the right within a T-slot, which in turn drives a push rod to the right. The push rod's movement to the right then drives the lower left movable rod to move synchronously to the right.
[0004] While the aforementioned patent improves the operating efficiency of the device by setting the turntable in a semi-circular shape, which facilitates the simultaneous operation of the two moving rods, it still relies on manual handling when placing heavy and bulky cement rods. This significantly increases labor costs and reduces handling efficiency. Furthermore, it lacks a structure to automatically transport the cement rods into the steam kiln and to precisely monitor the humidity and temperature inside the steam kiln. Imbalances in temperature and humidity can severely impact the curing effect on the cement rods. Therefore, this paper proposes a steam curing kiln for cement rods to address these issues. Utility Model Content
[0005] In order to overcome the shortcomings of existing technologies and solve the problems existing in existing steam curing kilns for cement poles, this utility model proposes a steam curing kiln for cement poles.
[0006] The technical solution adopted by this utility model to solve its technical problem is: the cement rod steam curing kiln of this utility model includes a curing kiln, and a pushing component is provided inside the curing kiln. The pushing component includes a mounting seat fixed to the inner wall, a drive motor and a lead screw in the sliding groove on the top surface of the mounting seat, a moving block threadedly connected to the lead screw, a bottom support on the top of the moving block, and an extrusion block driven by a bracket and a bolt rod on the bottom support.
[0007] The top of the curing kiln is equipped with a monitoring component, which includes a temperature sensor with an embedded temperature probe, a humidity sensor with an embedded adjacent humidity probe, and a controller inside an explosion-proof box.
[0008] Preferably, a steam generating structure is fixed on the top surface of the curing kiln, and the steam generating structure is connected to an exhaust pipe that runs through the inside of the curing kiln via a solenoid valve. The controller is electrically connected to both the solenoid valve and the drive motor.
[0009] Preferably, the extrusion block is vertically raised and lowered by a bearing at the bottom of the bolt rod, the base and the support plate form a horizontal bearing surface, and the moving block moves along the slide groove, causing the base and the support plate to move relative to each other.
[0010] Preferably, the signal output terminals of the temperature sensor and humidity sensor are connected to the controller, and the controller adjusts the opening and closing degree of the solenoid valve and the start and stop of the drive motor based on the monitoring data.
[0011] Preferably, when the bolt rod rotates, the bearing drives the extrusion block to clamp the cement rod on the base, and the drive motor drives the moving block through the lead screw to pull the cement rod into the curing kiln.
[0012] Preferably, the side of the curing kiln is connected to a sealing plate with a snap-fit structure via a hinge, and the bottom is supported by a bracket, one of which is connected to a support plate via a connecting plate.
[0013] The advantages of this utility model are:
[0014] 1. This utility model achieves the automatic clamping and displacement transportation of cement poles between the base and the support plate by using the drive motor of the component to drive the lead screw to move the moving block and the base plate, and in conjunction with the structural design of the extrusion block driven by the bolt rod on the bracket. This solves the problem of relying on manual handling for large-volume cement poles and improves the efficiency of cement pole handling.
[0015] 2. This utility model uses temperature and humidity sensors in the monitoring components to collect real-time data inside the curing kiln. Combined with the controller's dynamic adjustment of the solenoid valve's opening and closing degree, it precisely controls the steam supply of the outlet pipe, achieving the function of stabilizing the temperature and humidity environment. This solves the problem of excessively high or low humidity and temperature affecting the curing quality and improves the curing quality of cement poles. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figures 1-4 As shown, a steam curing kiln for cement bars includes a curing kiln 1. The curing kiln 1 is equipped with a pushing assembly 2. The pushing assembly 2 includes a mounting base 21 fixed to the inner wall, a drive motor 22 and a lead screw 23 in the sliding groove on the top surface of the mounting base 21, a moving block 24 threadedly connected to the lead screw 23, a bottom support 25 on the top of the moving block 24, and an extrusion block 29 driven by a bracket 26 and a bolt rod 27 on the bottom support 25.
[0024] During operation, the mounting base 21 is fixed to both sides of the inner wall of the curing kiln 1, and the chute on its top surface extends along the length of the curing kiln 1. The drive motor 22 is installed at one end of the chute, and its output end is coaxially connected to the lead screw 23 that passes through the chute. The surface of the lead screw 23 has a threaded structure that matches the bottom of the moving block 24. The moving block 24 is embedded in the chute and threaded with the lead screw 23. Its top extends out of the chute and is fixedly connected to the bottom surface of the base support 25. A bracket 26 is vertically welded to the surface of the base support 25. A threaded hole at the top of the bracket 26 is connected to a bolt rod 27. The bottom end of the bolt rod 27 is movably connected to the pressing block 29 through a bearing 28. When the bolt rod 27 is rotated, the pressing block 29 moves up and down along the axis of the bearing 28, forming an adjustable clamping space between itself and the surface of the base support 25. After the drive motor 22 is started, the lead screw 23 drives the moving block 24 to move horizontally along the chute, so that the base support 25 carrying the cement rod moves synchronously, realizing automated transportation.
[0025] Furthermore, a monitoring component 6 is provided on the top of the curing kiln 1. The monitoring component 6 includes a temperature sensor 61 embedded in a temperature probe hole, a humidity sensor 62 embedded in an adjacent humidity probe hole, and a controller 64 inside an explosion-proof box 63. A steam generating structure 3 is fixed on the top surface of the curing kiln 1. The steam generating structure 3 is connected to the gas outlet pipe 5 that runs through the inside of the curing kiln 1 through a solenoid valve 4. The controller 64 is electrically connected to the solenoid valve 4 and the drive motor 22 respectively.
[0026] During operation, temperature probe holes and adjacent humidity probe holes are opened along the length of the top surface of curing kiln 1. Temperature sensors 61 are embedded in the temperature probe holes, with their probes extending to the center of the internal cavity of curing kiln 1. Humidity sensors 62 are embedded in the humidity probe holes, with their probes parallel to those of temperature sensors 61 and spaced 10-15 cm apart. An explosion-proof enclosure 63 is bolted to the side of the humidity probe holes. A controller 64 is installed inside the enclosure. The input terminals of the controller 64 are connected to the temperature sensors 61 and 62 via shielded wires, and the output terminals are electrically connected to the solenoid valve 4 and the drive motor 22 via cables. The probe holes of temperature sensors 61 and 62 are filled with high-temperature resistant sealant. A heat-insulating gasket is placed between the explosion-proof enclosure 63 and the top surface of curing kiln 1. During monitoring, temperature sensors 61 collect cavity temperature data in real time, humidity sensors 62 simultaneously detect steam humidity, and the controller 64 dynamically adjusts the opening of the solenoid valve 4 and the operating speed of the drive motor 22 by comparing with preset thresholds to achieve precise control of the curing environment.
[0027] Furthermore, a steam generating structure 3 is fixed on the top surface of the curing kiln 1. The steam generating structure 3 is connected to the gas outlet pipe 5 that runs through the inside of the curing kiln 1 via a solenoid valve 4. The controller 64 is electrically connected to the solenoid valve 4 and the drive motor 22 respectively.
[0028] During operation, the steam generating structure 3 is connected to the solenoid valve 4 and the exhaust pipe 5. Combined with the control of the opening of the solenoid valve 4 by the controller 64, the steam supply is dynamically achieved, ensuring that the steam environment inside the curing kiln 1 quickly reaches the set parameters, avoiding the lag of traditional manual adjustment.
[0029] Furthermore, when the bolt rod 27 rotates, it drives the extrusion block 29 to clamp the cement rod on the base support 25 through the bearing 28, and the drive motor 22 drives the moving block 24 through the lead screw 23 to pull the cement rod into the curing kiln 1.
[0030] During operation, the bolt rod 27 rotates and drives the pressing block 29 through the bearing 28 to form an adjustable clamping force, which avoids damage to the surface of the cement rod due to rigid extrusion. At the same time, the drive motor 22 drives the moving block 24 through the lead screw 23 to achieve stepless speed change, thereby improving transportation efficiency.
[0031] Furthermore, the side of the curing kiln 1 is connected to the sealing plate 8 with the snap-fit structure 9 via the hinge 7, and the bottom is supported by the support 10, one of which is connected to the support plate 12 via the connecting plate 11.
[0032] During operation, the quick-locking design of the sealing plate 8 connected by the hinge 7 and the snap-fit structure 9, combined with the load-bearing support structure of the bracket 10 and the connecting plate 11, forms a seamless connection between the enclosed maintenance space and the external load-bearing platform, realizing efficient loading and unloading and sealing operations in one, reducing steam leakage and heat loss.
[0033] Working principle: After the cement rod is placed on the horizontal bearing surface formed by the base 25 and the support plate 12, the bolt rod 27 on the rotating bracket 26 drives the extrusion block 29 to press down vertically through the bearing 28, clamping and fixing the cement rod. After the drive motor 22 starts, it drives the lead screw 23 to rotate, causing the moving block 24 to move inward along the sliding groove of the mounting base 21, driving the base 25 and the cement rod to slide into the curing kiln 1 synchronously. The sealing plate 8 is closed by the hinge 7 and locked by the snap-fit structure 9, forming a closed curing space. The steam generated by the steam generating structure 3 is injected into the kiln through the outlet pipe 5 after the flow rate is regulated by the solenoid valve 4. The temperature sensor 61 and humidity sensor 62 monitor the internal environment in real time. The controller 64 dynamically adjusts the opening of the solenoid valve 4 according to the data to control the steam supply, and at the same time regulates the start and stop and the moving speed of the drive motor 22. After curing is completed, the drive motor 22 rotates in reverse, the base 25 moves out with the cement rod, and the extrusion block 29 is released to unload the material. By promoting the automated transportation of component 2, monitoring the closed-loop control of component 6, and the synergistic effect of the sealing structure, efficient and precise steam curing of cement poles can be achieved.
[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
