Description

Technical Field

[0001] This utility model relates to the field of refractory material conveying technology, specifically a material conveying device for an unshaped refractory material packaging machine. Background Technology

[0002] Unshaped refractories, also known as bulk refractories, are composed of refractory aggregates, powders, binders, and additives mixed in a specific ratio, requiring no molding or firing process before use. Their main components include aggregates such as bauxite, mullite, and corundum; powders such as high-alumina powder and corundum powder; and binders such as calcium aluminate cement and phosphates.

[0003] Currently, the material conveying devices for packaging machines for unshaped refractory materials have formed a mature technology system centered on adapting to material characteristics. A multi-type conveying technology framework has been constructed to meet the material handling requirements of particle sizes of 0-5mm and temperatures ≤700℃. In mainstream solutions, screw conveyors generally adopt a design combining high-manganese steel blades with ceramic fiber linings, equipped with a dual-stage sealing system and frequency conversion drive, achieving stepless speed regulation from 0.1-1.2m / s.

[0004] However, the conveying devices used in the existing technology are prone to long processing time and processes when conveying unshaped refractory materials, which leads to wear on the conveying blades. When it comes to inspecting, disassembling, replacing or cleaning the blades, the entire blade needs to be disassembled and replaced or cleaned, resulting in relatively large losses.

[0005] Therefore, we urgently need to provide a material conveying device for packaging machines of unshaped refractory materials. Utility Model Content

[0025] 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 protection scope of the present utility model.

[0026] Example 1:

[0027] The existing conveying devices used in current technology are prone to wear on the conveying blades when conveying unshaped refractory materials due to the long processing time and procedures. Repairing, disassembling, replacing, or cleaning these blades requires disassembling and replacing the entire blade, resulting in relatively significant losses. Please refer to [reference needed]. Figures 1-5 The embodiment provides a material conveying device for an unshaped refractory packaging machine, which can effectively improve the cost and efficiency of disassembling, replacing and maintaining the conveying device. The material conveying device for the unshaped refractory packaging machine includes a base 1, an adjusting device installed on the top of the base 1, a conveying device installed on the top of the adjusting device, and a feeding device installed on the top left end of the conveying device.

[0028] The conveying device includes a conveying structure and a main structure, with the conveying structure installed in the middle of the main structure. The conveying structure includes a conveying motor 105, the output end of which is connected to a main shaft 106. A flange 107 is installed on the end of the main shaft 106 furthest from the conveying motor 105. A spiral blade 108 is connected to the side of the flange 107 furthest from the main shaft 106, and a secondary shaft 109 is connected to the right end of the spiral blade 108. The main structure includes a conveying cylinder 101, with an inspection port 102 installed in the center of the front surface of the outer surface of the conveying cylinder 101. A discharge port 103 is installed at the right end of the bottom of the conveying cylinder 101, and an ultrasonic vibrator 104 is installed in the center of the left side of the discharge port 103.

[0029] The conveyor motor 105 is detachably installed on the left end of the conveyor cylinder 101. The main shaft 106 is connected to the middle of the left end of the conveyor cylinder 101 through a sealed bearing. The auxiliary shaft 109 is connected to the middle of the right end of the conveyor cylinder 101 through a sealed bearing. The outer surface of the spiral blade 108 is slidably connected to the inner wall of the conveyor cylinder 101.

[0030] By using a conveying device, multiple spiral blades 108 are detachably connected via flanges 107, which facilitates the disassembly, cleaning, and maintenance of the spiral blades 108, while reducing maintenance costs.

[0031] The helical blade 108 adopts a multi-segment design with a pitch of 200-250mm and a blade thickness of 8-12mm. It is made of ZGMn13 wear-resistant high-manganese steel. Each segment of the helical blade 108 is welded to both ends with flanges 107, with specifications ranging from DN150 to DN200. The flanges 107 are connected using 4-6 M16×30 high-strength bolts (grade 8.8). A nitrile rubber gasket with a temperature resistance of over 300℃ is installed between the bolts and the flanges 107 (to prevent material leakage). The main shaft 106 and the auxiliary shaft 109 have a diameter of 50-60mm and are made of 45# steel (quenched and tempered, hardness HRC28-32). The main shaft 106 is connected to the flange 107 of the first segment of the helical blade 108 using a key (key specification 16×10×50). The auxiliary shaft 109 is also connected to the flange 107 of the last segment of the helical blade 108 using a key. A 10-15mm positioning step is provided at the shaft end to ensure blade coaxiality.

[0032] The conveying cylinder 101 has an inner diameter of 160-220mm and is made of Q345B steel plate (wall thickness 8-10mm). The inner wall of the cylinder can be optionally lined with a 1-2mm thick Al2O3 ceramic lining. The end caps of the conveying cylinder 101 are connected to the cylinder body by flanges for easy disassembly and maintenance. The inspection port 102 is located at the connection position of the flange 107 of each section of the spiral blade 108. Each section of the blade corresponds to one inspection port. The inspection port is rectangular with a size of 300×250mm. The flange is welded to the edge of the port. The cover plate is fastened with bolts (M12×20 bolts, 4 bolts). A heat-resistant sealing gasket (material same as the flange gasket) is installed on the inside of the cover plate. A handle is welded to the outside of the cover plate for easy opening. Both the main shaft 106 and the auxiliary shaft 109 use double-end mechanical seal bearings (model 22212CC / W33). The sealing cavity is filled with high-temperature resistant grease (model HT500, applicable temperature -20℃-200℃). The bearing housing and the end cover of the conveying cylinder 101 are connected by bolts (M10×20 bolts, 6 bolts) to prevent material dust from entering the bearing cavity. The ultrasonic vibrator 104, model CSB-2040, has a working power of 400W and a vibration frequency of 20-40kHz. It is fixed by bolts (M8×15 bolts, 4 bolts) to the left side of the cylinder wall of the discharge port 103 (50-80mm from the discharge port). A shock-absorbing pad (silicone material, 3mm thick, to reduce vibration transmission to the base) is installed between the vibrator and the cylinder wall. The discharge port 103 has a diameter of 100-150mm and is made of the same material as the conveyor cylinder 101. The inner wall of the discharge port 103 is rounded (rounded corner radius of 5mm to prevent material accumulation). A manual gate valve (model Z41H-16C) can be optionally installed for easy control of discharge start and stop.

[0033] When conveying refractory materials, the conveying motor 105 is started to drive the main shaft 106 to rotate. The main shaft 106 is connected to the multi-segment spiral blades 108 via the flange 107. The spiral blades 108 are detachably connected to the auxiliary shaft 109. The main shaft 106 and the auxiliary shaft 109 are connected to the conveying cylinder 101 via sealed bearings, thereby driving the spiral blades 108 to convey the refractory materials. When the spiral blades 108 experience wear after use, the inspection port 102 installed on the outer surface of the conveying cylinder 101 facilitates quick disassembly of the flange 107 connection, effectively improving the efficiency of inspection and disassembly. The detachable connection of the multi-segment spiral blades 108 effectively reduces the cost of maintenance and replacement. After conveying, the material is discharged through the discharge port 103. During the discharge process, the vibration of the ultrasonic vibrator 104 reduces material bridging, thereby effectively preventing blockage during material discharge.

[0034] Example 2:

[0035] Based on Implementation 1, existing technologies still have issues with the inconvenience of adapting and flexibly adjusting the material conveying angle, and the need to prevent material drop and impact during feeding, which could lead to material accumulation and adhesion. Please refer to [reference needed]. Figures 1-5 This embodiment provides a material conveying device for an unshaped refractory material packaging machine, which can effectively solve the problems of flexible adjustment of the conveying angle and easy accumulation and adhesion of materials during the feeding process. The material conveying device for the unshaped refractory material packaging machine includes an adjusting device including an asynchronous motor 201. An adjusting component 202 is connected to the output end of the asynchronous motor 201. A moving block 203 is installed in the middle of the outer surface of the adjusting component 202. A hydraulic cylinder 204 is installed on the top of the moving block 203. A hinge 205 is installed at the output end of the hydraulic cylinder 204. A hydraulic cylinder 206 is arranged on the left side of the hydraulic cylinder 204. A hinge 207 is installed at the output end of the hydraulic cylinder 206. The asynchronous motor 201 is detachably installed at the middle right end of the base 1. The outer surface of the moving block 203 is slidably connected to the inner wall of the sliding groove at the middle right end of the top surface of the base 1. The bottom of the hydraulic cylinder 206 is detachably connected to the middle of the top surface of the base 1 near the left end. The top of the hinge 1 205 and the hinge 2 207 are hinged to the outer surface of the conveying cylinder 101.

[0036] The feeding device includes a feed inlet 301, a rotating shaft 302 connected to the middle of the feed inlet 301, a guide plate 303 mounted on the middle of the outer surface of the rotating shaft 302, a torsion spring 304 mounted on one end of the front and back of the rotating shaft 302, and a piezoelectric ceramic micro-vibrator 305 mounted on the middle of the bottom surface of the guide plate 303. The feed inlet 301 is fixedly installed on the top left end of the conveying cylinder 101, the outer surface of the rotating shaft 302 is rotatably connected to the inner wall of the circular hole in the feed inlet 301, and the end of the torsion spring 304 away from the rotating shaft 302 is fixedly connected to the outer surface of the feed inlet 301.

[0037] By adjusting the device and the feeding device, the conveying angle of the conveying cylinder 101 can be adapted and adjusted. At the same time, the installation of the torsion spring 304 and the guide plate 303 buffers the feeding while the piezoelectric ceramic micro-vibrator 305 effectively prevents the feeding material from piling up and sticking together.

[0038] The asynchronous motor 201, model Y80M1-2, has a rated power of 0.75kW and a rated speed of 2840r / min. The motor is equipped with an electromagnetic braking device (braking within 0.5s after power failure to prevent the moving block from slipping). The motor is bolted to the base (1) via a motor seat (made of Q235 steel) (M10×25 bolts, 4 bolts). The motor output shaft and the adjusting component (202) are connected by a coupling (elastic coupling, model XL3, to compensate for coaxiality error). The adjusting component 202 consists of a threaded rod and a threaded cylinder. The threaded rod has a diameter of 30-40mm, a pitch of 5-8mm, and is made of 40Cr (heat treatment, hardness HRC28-32). The surface is plated with hard chrome (thickness 0.05mm, to improve wear resistance). The inner diameter of the threaded cylinder matches that of the threaded rod, the cylinder wall thickness is 8-10mm, and the material is also 40Cr. The threaded cylinder and the moving block (203) are connected by welding (full welding, weld height 6mm).

[0039] The movable block 203 is a cuboid (150×100×80mm) made of Q345B steel. Two sets of linear guide sliders (model HGW20CC, compatible with HGR20 guide rails) are mounted on its bottom. The guide rails are fixed within the sliding grooves of the base 1. The sliding grooves are located at the right end of the center of the top surface of the base, with a width of 50-60mm and a depth of 30-40mm. The length of the guide rail matches the adjustment stroke of the movable block (typically 300-500mm). Limiting blocks (made of rubber to prevent impact) are provided at both ends of the groove. Grease passages are provided on the guide rail surface, with grease fittings (model M6×1) at the ends of the passages. It is recommended to inject lithium-based grease (model GB / T7324-2010, No. 2) every 500 hours of operation to prevent guide rail wear. Both hydraulic cylinder 1 (204) and hydraulic cylinder 2 (206) are model HOB40×100-FA, with a working pressure of 10-16MPa, a rated thrust of 12.56-20.10kN, and a stroke of 100mm (150mm or 200mm stroke can be selected according to angle adjustment requirements). The cylinder body is made of No. 20 seamless steel pipe, and the piston rod is made of No. 45 steel (chrome-plated surface, 0.05mm thick). A one-way throttle valve (model L-10H, for adjusting lifting speed) is installed at the oil inlet of the hydraulic cylinder. Both hinge 1 (205) and hinge 2 (207) are double-ear hinge structures, made of 45 steel (heat treated), with a hinge hole diameter of 25mm. A copper sleeve (made of ZCuSn5Pb5Zn5 to reduce wear) is installed inside the hole. The top of the hinge is welded to the conveyor cylinder (101) (welding position: hinge 1 is 200-300mm from the right end of the conveyor cylinder, and hinge 2 is 300-400mm from the left end of the conveyor cylinder). The bottom is connected to the hydraulic cylinder piston rod by a pin (pin diameter 24mm, made of 40Cr, and fixed at both ends with cotter pins). The feed inlet 301 has a funnel-shaped structure with an upper diameter of 300-400mm and a lower diameter matching the inner diameter of the conveyor cylinder 101 (160-220mm). It is made of Q235B steel plate (5-6mm wall thickness). The lower opening is welded to the conveyor cylinder (full weld, 5mm weld height), and the upper edge is welded with a flange (10mm width to prevent material spillage). The rotating shaft 302 has a diameter of 20-25mm and is made of 45# steel (heat treated). Its length matches the width of the feed inlet (320-420mm). Both ends of the shaft are connected to the sidewalls of the feed inlet via deep groove ball bearings (model 6205). The bearing seats are fixed with bolts (M8×15 bolts, 2 bolts). An annular groove (5mm wide, 2mm deep, to prevent slippage of the torsion spring) is provided at the connection point between the shaft end and the torsion spring 304.The guide plate 303 is a rectangular plate structure with a length of 250-350mm, a width of 150-200mm, and a thickness of 5-8mm. It is made of NM400 wear-resistant steel plate (suitable for material impact and wear). The guide plate is welded to the rotating shaft (302) in the middle (welding length 100-150mm, weld height 4mm). Two to three 10mm diameter weight-reducing holes are opened on the plate surface (evenly distributed to reduce rotational inertia). The piezoelectric ceramic microvibrator 305, model PZT-40 / 5, has a working power of 50-80W, a vibration frequency of 50-100Hz, and a working voltage of 220VAC. The microvibrator is fixed to the center of the bottom surface of the guide plate 303 with bolts (M6×10 bolts, 2 bolts). An insulating gasket (made of epoxy resin, 2mm thick, to prevent leakage) is installed at the fixing position. The microvibrator wires are led out through the internal wiring hole of the rotating shaft (to avoid wire tangling). The torsion spring 304 is made of 60Si2Mn spring steel with a wire diameter of 3-4mm, an outer diameter of 20-25mm, an effective number of coils of 5-6, a free length of 50-60mm, and a stiffness of 1.5-2.0N・m / rad. One end of the torsion spring is embedded in the annular groove of the rotating shaft 302, and the other end is welded to the side wall of the feed port 301 (the welding point is 50-60mm away from the center of the rotating shaft). The initial preload is 5-8N・m (to ensure that the guide plate is tilted at an angle of 30°-45° in its natural state, so as to achieve feed buffering).

[0040] When adjusting the conveying angle of the conveying cylinder 101, hydraulic cylinder 204 is activated to drive hinge 205 to adjust the height of the right end of the conveying cylinder 101. At the same time, hydraulic cylinder 206 drives hinge 207 to rise and fall, effectively ensuring flexible adjustment of the angle of the conveying cylinder 101. When hydraulic cylinder 204 drives hinge 205 to rise and fall, asynchronous motor 201 is activated to drive adjusting component 202 for transmission. The output end of asynchronous motor 201 drives threaded rod to rotate. The outer surface of threaded rod is connected to the internal thread of threaded cylinder. The outer surface of threaded cylinder is fixedly connected to moving block 203. Thus, moving block 203 drives hydraulic cylinder 204 to move, preventing motion interference when adjusting the angle of conveying cylinder 101. Meanwhile, when feeding at the feed inlet 301, the connection between the guide plate 303 and the rotating shaft 302, as well as the torsion springs 304 installed at both ends of the rotating shaft 302, facilitate the buffering and adjustment of the rotation angle of the guide plate 303, thereby achieving the buffering of the feeding by the guide plate 303. Furthermore, the piezoelectric ceramic micro-vibrator 305 installed at the bottom of the guide plate 303 facilitates the micro-vibration of the guide plate 303, preventing material adhesion while effectively reducing material dust caused by vibration.
