Description

Technical Field

[0001] This utility model relates to the field of transition kilns, and in particular to a template system for construction of transition kiln castables. Background Technology

[0002] Castable refractory is a common lining material for transition kilns. Its construction requires the use of formwork for fixing and shaping. On-site, wooden formwork is often used for segmented transition kiln construction. However, because the inner ring of the transition kiln is elliptical in a cold state, conventional wooden formwork makes it difficult to precisely control the thickness of the castable refractory, leading to uneven thermal stability of the cast layer and subsequent cracking and detachment. Furthermore, excessive circumferential segmentation also results in too many construction joints and material embedding, compression, and breakage.

[0003] Patent No. CN209655811U discloses a steel template for rotary kiln refractory construction. The steel template is composed of convex and concave steel templates connected by tenons and mortises. However, it also has problems such as uneven thickness of refractory and leakage. Patent No. CN 219599865U discloses a refractory construction mold unit and a refractory construction mold. The mold fixes the refractory between the vertical arc-shaped outer mold surface and the inner wall. However, this method is not suitable for refractory construction in rotary kilns.

[0004] To address the problems of uneven thickness and excessive construction joints in the current construction of castable refractory for transition kilns, a template system and installation / removal method for castable refractory construction in transition kilns are proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a template system for construction of transition kiln castables, which addresses the above-mentioned shortcomings. It solves the problems of the existing technology where the construction of transition kiln castables using wooden molds usually involves a large number of circumferential divisions, requiring multiple kiln rotations, resulting in slow construction. Furthermore, the excessive number of construction joints can lead to material entry and thermal extrusion breakage. At the same time, it solves the problem that in the existing technology, the inner ring of the transition kiln is elliptical in the cold state, making it difficult to accurately control its thickness with conventional wooden molds, resulting in uneven thickness after molding, uneven thermal deformation, and easy cracking and breakage.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1) This solution uses a strut assembly to connect to the inner wall of the transition kiln, thus fixing the entire template system. The use of retractable connecting rods allows the truss assembly and template assembly to adapt to the shape of the transition kiln's inner wall. This solves the problem in existing technologies where the inner ring of the transition kiln is elliptical in the cold state, making it difficult to precisely control the thickness of conventional wooden molds, resulting in uneven thickness and easy cracking and breakage after molding. Simultaneously, by setting the coverage area of ​​the template assembly to at least one-third of the transition kiln's inner wall cross-section, the pouring operation can be completed with fewer kiln rotations. This improves construction efficiency and reduces the formation of construction joints, preventing material from embedding into the joints of the poured layers and causing crushing.

[0019] 2) This solution can precisely control the uniformity of the refractory thickness according to the ellipticity of the kiln body; at the same time, the template component can be assembled outside the kiln and then moved into the kiln by a simple trolley, making installation and disassembly convenient; the casting of each ring can be completed by loosening the hydraulic cylinder once and turning it once, resulting in fast refractory construction speed, fewer construction joints, and low risk of material intrusion.

[0030] Example 1

[0031] like Figures 1-5 As shown, this utility model provides a technical solution:

[0032] A template system for construction of castable refractory in a conversion kiln includes, but is not limited to, a strut assembly 1, a truss assembly 2, and a template assembly 3. The strut assembly 1 is detachably connected to the inner wall 4 of the conversion kiln via a support member. The strut assembly 1 is telescopically connected to the truss assembly 2 via a connecting rod. The truss assembly 2 is connected to the template assembly 3. The template assembly 3 is pressed against the inner wall 4 of the conversion kiln with a predetermined support force through the telescopic connecting rod. The template assembly 3 covers at least one-third of the cross-section of the inner wall 4 of the conversion kiln.

[0033] Based on the above structure, the entire template system is fixed by connecting the strut assembly 1 to the inner wall 4 of the transition kiln. By setting a telescopic connecting rod, the truss assembly 2 and the template assembly 3 can adapt to the shape of the inner wall 4 of the transition kiln. This solves the problem in the prior art that the inner ring of the transition kiln is elliptical in the cold state, and it is difficult to accurately control its thickness with conventional wooden molds, resulting in uneven thickness and easy cracking and breakage after molding. At the same time, the coverage of the template assembly 3 is set to cover half of the cross-section of the inner wall 4 of the transition kiln. The pouring operation can be completed with fewer kiln rotations. On the one hand, it can improve construction efficiency, and on the other hand, it can reduce the generation of construction joints and avoid material embedding in the joint of the poured layer, which would cause it to be squeezed and broken.

[0034] As an example, the strut assembly 1 may include a support portion 11, a telescopic portion 12, and a connecting portion 13; the connecting portion 13 is coaxially sleeved in the length direction of the support portion 11, and the telescopic portions 12 are evenly spaced along the circumference of the connecting portion 13; the connecting portion 13 is rotatable relative to the support portion 11, and a locking device for locking the connecting portion 13 is provided on the support portion 11; a vertical rod 112 is provided in the support portion 11 and connected to the inner wall 4 of the transformation kiln.

[0035] Based on the above structure, the entire support part 11 is supported by the vertical rod 112 and forms a stable connection structure with the inner wall 4 of the transformation kiln. Through the connecting part 13 that rotates relative to the support part 11, the next pouring area can be constructed by rotating the transformation kiln after the predetermined area is poured, without the need to set up additional connection points. The truss assembly 2 and the template assembly 3 connected to the truss assembly 2 rotate synchronously relative to the support part 11 at the specified position, which can ensure that adjacent pouring units are in the same position within the same annular plane, thus ensuring the integrity of the poured body within the same annular plane.

[0036] As an example, the support 11 may include a central rod 111 and a vertical rod 112. The vertical rod 112 is vertically arranged on both sides of the central rod 111. One end of the vertical rod 112 is connected to the inner wall 4 of the transformation kiln through a stiffening plate 116, and the other end is connected to the central rod 111 by locking.

[0037] A pre-reserved part 113 is welded to the inner wall 4 of the transformation kiln. One end of the vertical rod 112 is connected to the pre-reserved part 113 through a stiffening plate 116, which can ensure the connection strength between the vertical rod 112 and the transformation kiln.

[0038] The locking component can be a clamp structure. A first clamp 114 and a second clamp 115 are provided on the end of the vertical rod 112 away from the inner wall 4 of the transformation kiln. The two ends of the first clamp 114 and the second clamp 115 are connected by bolts. A groove structure that matches the size of the central rod 111 is provided at the center of the first clamp 114 and the second clamp 115. The central rod 111 is inserted into the central groove structure to achieve quick assembly and disassembly with the vertical rod 112.

[0039] Based on the above structure, in this solution, a reserved part 113 is set on the inner wall 4 of the transformation kiln to provide a connection foundation for the vertical rod 112, and the stiffening plate 116 makes the entire support system more stable. The locking part of the clamp structure can quickly assemble and disassemble the central rod 111 and the vertical rod 112, reducing the difficulty of later assembly.

[0040] As an example, the telescopic part 12 may include a fixed support rod 121, a telescopic support rod 122, and a telescopic mechanism; the telescopic mechanism is disposed between the telescopic support rod 122 and the fixed support rod 121, and the end of the fixed support rod 121 away from the telescopic mechanism is connected to the connecting part 13; the end of the telescopic support rod 122 away from the telescopic mechanism is connected to the truss system through a support rod connector; the support rod connector is a pin-connected rotatable structure (the telescopic rod moves flexibly during extension and retraction to ensure the reliability of the structure).

[0041] Based on the above structure, the length of the entire telescopic part 12 can be adjusted by the telescopic mechanism, thereby realizing the self-adjustment of the inner diameter of the transformation kiln. Since it is designed for the case where the inner ring of the transformation kiln is elliptical in a cold state, this device can achieve the same thickness of casting layer for transformation kilns in different forms. Ensuring the consistency of the casting layer thickness can avoid cracking and damage caused by different expansion coefficients after heating.

[0042] As an example, the telescopic mechanism may specifically include a hydraulic cylinder 123, a hydraulic baffle 124, a hydraulic rod 125, and a connecting spring 126. A hydraulic chamber 127 is provided in the hydraulic cylinder 123, and the hydraulic baffle 124 is disposed within the hydraulic chamber 127. The hydraulic chamber 127 also has an oil hole 128 connecting to the outside; the oil hole 128 facilitates the input and output of hydraulic oil into the hydraulic chamber 127. The hydraulic rod 125 is connected to the hydraulic baffle 124. A spring chamber 129 is provided around the circumference of the hydraulic rod 125 in the telescopic mechanism. The connecting spring 126 is disposed within the spring chamber 129, with one end connected to the end of the spring chamber 129 and the other end connected to the circumferential position of the end of the telescopic support rod 122. The hydraulic rod 125 is connected to the center position of the end of the telescopic support rod 122. Lubricating grease may be provided in the hydraulic chamber 127.

[0043] Based on the above structure, the position of the hydraulic baffle 124 can be adjusted by inputting or outputting hydraulic oil into the hydraulic chamber 127 through the oil hole 128. The left and right movement of the telescopic support rod 122 is driven by the hydraulic rod 125. When a retraction movement is required, the connecting spring 126 in the stretched state can provide pull-back assistance. The working principle of the telescopic mechanism extension / retraction is as follows: the telescopic mechanism extends; oil is injected into the oil hole 128 → the oil pressure of the hydraulic cylinder 123 increases → the hydraulic baffle 124 pushes the telescopic support rod 122 connected to the hydraulic rod 125 closer to the template → the spring is stretched → until the template is pressed against the inner wall 4 of the transformation kiln; the telescopic mechanism retracts; oil is slowly returned from the oil hole 128 → the spring rebounds → the telescopic support rod 122 retracts. The grease-containing cavity provides the movement stroke for the telescopic support rod 122. The telescopic mechanism is used to press the template system against the inner wall 4 of the transformation kiln to achieve control of the thickness of the transformation kiln castable.

[0044] As an example, the connecting part 13 may include a strut connecting sleeve 131 and a rotary bearing 132; the strut connecting sleeve 131 is rotatably connected to the central rod 111 via the rotary bearing 132;

[0045] Multiple telescopic parts 12 are provided at intervals within a circumferential range of 90°, 120° or 180° of the connecting sleeve; the template assembly 3 is fixed as a whole by connecting the multiple telescopic parts 12 with the truss assembly 2.

[0046] The coverage range of the selected expansion joint 12 is chosen according to actual needs. For example, if the expansion joint 12 with a coverage range of 90° is selected, it can pour one-quarter of the ring surface each time, and it requires 3 kiln rotations to complete the construction of the entire ring surface. If the expansion joint 12 with a coverage range of 120° is selected, it can pour one-third of the ring surface each time, and it requires 2 kiln rotations to complete the construction of the entire ring surface. If the expansion joint 12 with a coverage range of 180° is selected, it can pour half of the ring surface each time, and it requires 1 kiln rotation to complete the construction of the entire ring surface.

[0047] As an example, the locking device may include a friction ring 133 and a locking nut 134, with external threads provided at least in a partial area at both ends of the central rod 111, the locking nut 134 being sleeved on the external threads on both sides of the central rod 111, and the friction ring 133 being provided at both ends of the support rod connecting sleeve 131;

[0048] Based on the above structure, the friction ring 133 is resisted by rotating the locking nuts 134 on both sides, and finally the position of the center rod 111 and the support connecting sleeve is locked (the front and rear locking nuts 134 on the center rod 111 are tightened and squeezed by the friction ring 133 to generate friction locking).

[0049] As an example, the truss assembly 2 may include multiple truss units 21, adjacent truss units 21 are connected by U-shaped buckles 22, and truss elastic buckles 23 are also provided between adjacent truss units 21. The truss elastic buckles 23 are made of rubber, and the end face of the truss assembly 2 away from the telescopic part 12 is connected to the template assembly 3.

[0050] Based on the above structure, the telescopic part 12 is connected to the truss assembly 2 through the strut connector. The truss unit 21 is connected as a whole through multiple elastic buckles 23 that can deform elastically. When the telescopic strut 122 extends, the truss system undergoes elastic deformation, pressing the template system onto the inner wall 4 of the transformation kiln, thereby achieving control of the thickness of the elliptical 5 castable material on the inner wall 4 of the transformation kiln.

[0051] As an example, the template assembly 3 may include a steel mold 31, a vibration unit 32, a connecting unit 33, and a support unit 34; the vibration unit 32 is disposed on the steel mold 31 and can extend and retract along the thickness direction of the steel mold 31; the connecting unit 33 is disposed between the side plates of adjacent steel molds 31; the support unit 34 is disposed on one side plate of the steel mold and a sealing part 322 is provided at the end of the steel mold 31; the sealing part 322 may be a sealing strip.

[0052] The support unit 34 is located on the end of the steel mold 31 away from the already cast body.

[0053] Based on the above structure, the connecting unit 33 can strengthen the support strength of the two side plates of the steel mold 31 and avoid cavity deformation. The support unit 34 is set on one side plate of the steel mold to strengthen the support on one side. Since the pouring is done by contacting the already poured body on the front side, the support unit 34 does not need to be set on the contact side. The support unit 34 is set at the end away from the already poured body to prevent the poured concrete from overflowing from that side. The sealing part 322 can achieve the contact seal at the end to prevent material leakage.

[0054] As an example, the steel mold 31 may include a connecting horizontal plate 311, a first supporting side plate 312, a second supporting side plate 313, and an end plate; the connecting horizontal plate 311, the first supporting side plate 312, the second supporting side plate 313, and the end plate together constitute the cavity structure to be poured; the connecting unit 33 may be a high-temperature fiber 331 and a fiber fastener 332; the high-temperature fiber 331 is fixed between the first supporting side plate 341 and the second supporting side plate 313 by the fiber fastener 332;

[0055] Based on the above structure, the high-temperature fiber 331 can strengthen the cavity between the first support side plate 312 and the second support side plate 313, preventing deformation. The fiber lock 332 can enable the quick replacement of the high-temperature fiber 331, facilitating subsequent operations.

[0056] As an example, the support unit 34 may include a support side plate 341 and a switch magnetic strip 342; the support side plate 341 is connected to the end of the second side plate, and the switch magnetic strip is disposed at the end of the support side plate 341 away from the second support side wall.

[0057] Based on the above structure, since the inner side of the conversion kiln is a magnetically attracted metal structure, the switch magnetic strip 342 can be set to adjust the strength of its second support sidewall. The switch magnetic strip 342 and the high-temperature fiber 331 prevent the steel mold 31 casting material from being squeezed and deformed.

[0058] As an example, vibration units 32 can be spaced between truss assembly 2 and template assembly 3, and vibration units 32 are fixed to damping blocks 321 of truss unit 21.
