Description

Technical Field

[0001] This utility model relates to the field of refractory castable production technology, specifically to a refractory castable production device. Background Technology

[0002] Refractory castables are mixtures of refractory aggregates, binders, and admixtures, mixed with water (or liquid binders) to form a mortar suitable for casting. Unlike other monolithic refractories, refractory castables require a certain setting and hardening time after casting. Therefore, after casting, they need a certain curing period before demolding, followed by appropriate natural curing before baking and use.

[0003] For example, the authorization announcement number "CN220882817U" is titled "A Lightweight Refractory Castable Production Device with Crushing and Mixing Components." This device can crush agglomerated refractory castables, ensuring production efficiency and effectiveness. However, existing lightweight refractory castable production devices first crush large pieces of refractory castable through extrusion and grinding, then transport and mix them within a transverse spiral conveyor shaft, and finally filter and screen them. This process involves multiple layers of filter screens for screening, but the screens are simply stacked vertically without any additional structures to accelerate the refractory castable discharge and prevent clogging. As a result, the refractory castable is prone to clogging the filter screens, significantly impacting the production efficiency of the lightweight refractory castable production device.

[0004] Meanwhile, existing lightweight refractory castable production equipment generally requires subsequent filling of the refractory castable with a mixing agent and then uniformly and thoroughly mixing it inside a mixing device after crushing and sorting the refractory castable. The conventional mixing method uses a motor to drive the mixing rod vertically downward to stir the refractory castable. The refractory castable itself has a relatively high density, and its weight inside the mixing device is also very heavy. This will generate more wear and resistance on the rotating mixing rod. Therefore, long-term mixing will cause serious damage to the mixing rod, which will increase the production cost of refractory castable. Utility Model Content

[0005] The purpose of this invention is to solve the problems of low production efficiency and increased production cost of existing refractory castables, and to propose a refractory castable production device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a refractory castable production device, including a support plate, a crushing box, and a fixing plate. The crushing box is fixedly connected above the support plate, and the fixing plate is fixedly set on the ground on the side away from the support plate. The lower end of the support plate is provided with a refractory castable screening and feeding structure. The inner side of the crushing box is provided with a refractory castable extrusion and crushing structure. The top of the fixing plate is provided with a refractory castable stirring and mixing device.

[0008] Preferably, the refractory castable screening and feeding structure includes limiting blocks and a screening box. The screening box is fixedly connected to the lower end of the support plate. Multiple limiting blocks are fixedly connected to the inner wall of the screening box. Screening meshes are slidably connected above the multiple limiting blocks. Baffle plates are fixedly connected to the top of the multiple screening meshes. Multiple pushing rods are slidably connected to the side wall of the screening box. The front ends of the multiple pushing rods are fixedly connected to the side wall of the screening mesh.

[0009] Preferably, the front end of the outer wall of the screening box is rotatably connected to multiple material receiving gates via pins, and the inner sides of the multiple material receiving gates are arranged opposite to the lower end space of the screening screen.

[0010] Preferably, the refractory castable mixing device includes a positioning rod and a sleeve. The positioning rod is fixedly connected to one side of the top of the fixed plate. A flipping shaft is rotatably connected above the positioning rod. The sleeve is rotatably connected to the top of the flipping shaft. Multiple rotating bearings are fixedly connected to the inner side of the sleeve. A mixing tank is rotatably connected inside the rotating bearings. An agitator is fixedly installed inside the mixing tank. A first motor is fixedly installed on the outer wall of the bottom end of the sleeve. The output shaft of the first motor passes through the sleeve and is fixedly connected to the bottom end of the mixing tank.

[0011] Preferably, the mixing tank has a feeding hole fixedly provided at its front end.

[0012] Preferably, the refractory castable extrusion crushing structure includes a feed pipe and a discharge valve. The feed pipe is fixedly connected to the top of the crushing box. Two second motors are fixedly connected to the outside of the crushing box. Crushing rollers are fixedly installed at the output shaft ends of the two second motors. The discharge valve is fixedly connected to the bottom of the crushing box. The bottom of the discharge valve is connected to the inside of the screening box. A feeding trough is fixedly opened inside the crushing box.

[0013] The refractory castable production device proposed in this utility model has the following advantages: the operator can hold multiple push rods on the side and pull and shake them horizontally in sequence. The push rods can drive the screening screen to accelerate the discharge of blocked granules through the inertia of horizontal shaking. In this way, the screening screen of refractory castable is shaken by additional horizontal inertia, which reduces the situation of material blockage. Moreover, the crushed refractory castable is directly screened, eliminating the unnecessary spiral conveyor shaft mixing process and improving the production efficiency of the refractory castable production device.

[0014] When mixing refractory castables, connect the power supply and start the first motor at the bottom. The first motor will drive the mixing tank to rotate along the inner side of the casing under the rotating bearing. As the mixing tank rotates, the refractory castable and additives inside will be turned and stirred by gravity. The stirring wheel plays an auxiliary stirring function with less force. After the mixing is completed, the first motor is turned off. The operator uses mechanical equipment to rotate the casing along the turning shaft at a certain angle, so that the molded material inside the mixing tank can be poured out. The mixing tank's rotation is used to achieve the mixing process of high-density and high-weight refractory castables. The mixing effect is better while reducing the force and wear on the stirring rod, thus reducing the cost of refractory castable production equipment. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] Example 1:

[0024] Please see Figure 1-6In this embodiment, a refractory castable production device includes a support plate 1, a crushing box 2, and a fixing plate 3. The crushing box 2 is fixedly connected to the top of the support plate 1 and welded to the top of the support plate 1. The fixing plate 3 is fixedly set on the ground on the side away from the support plate 1. The lower end of the support plate 1 is provided with a refractory castable screening and feeding structure 6. The inner side of the crushing box 2 is provided with a refractory castable extrusion and crushing structure 5. The top of the fixing plate 3 is provided with a refractory castable stirring and mixing device 7.

[0025] The refractory castable screening and feeding structure 6 includes a limiting block 61 and a screening box 62. The screening box 62 is fixedly connected to the lower end of the support plate 1. The screening box 62 is used to screen and classify the crushed refractory castable according to the size of the aggregate particles. Multiple limiting blocks 61 are fixedly connected to the inner wall of the screening box 62. The limiting blocks 61 can support multiple screening plates 64 at the top, which are horizontally arranged inside the screening box 62. Screening mesh 64 is slidably connected above the multiple limiting blocks 61.

[0026] The screening mesh 64 is made of stainless steel metal mesh plate. The aperture of the screening mesh 64 gradually decreases from top to bottom, which can block refractory castable particles of different sizes for sorting. Multiple screening meshes 64 are fixedly connected to the top of the top of the meshes 64. The meshes 65 are set around the top of the screening meshes 64. The meshes 65 can prevent the screened particles from sliding out on both sides. Multiple push rods 63 are slidably connected to the side wall of the screening box 62. Therefore, when the crushing roller 54 squeezes the refractory castable and crushes it, it will fall down onto the screening mesh 64 and be initially screened by gravity.

[0027] Then, when material needs to be removed, the worker can hold the multiple push rods 63 on the side and pull and shake them horizontally in sequence. The push rods 63 can drive the screening screen 64 to accelerate the discharge of blocked particles through the inertia of horizontal shaking. The front ends of the multiple push rods 63 are fixedly connected to the side wall of the screening screen 64.

[0028] Multiple material picking doors 4 are rotatably connected to the front end of the outer wall of the screening box 62 via a pin. Multiple material picking doors 4 are provided, and the inner side of the multiple material picking doors 4 is relatively connected to the space screened out at the lower end of the screening screen 64. The material can be manually picked up after the material picking doors 4 are opened. The inner side of the multiple material picking doors 4 is relatively set to the lower end space of the screening screen 64.

[0029] The screening box 62 is used to screen and classify the crushed refractory castable according to the size of the aggregate particles. The limiting block 61 can support multiple screening plates 64 horizontally arranged inside the screening box 62. The screening mesh 64 is made of stainless steel metal mesh plate. The aperture of the screening mesh 64 gradually decreases from top to bottom, which can prevent refractory castable particles of different sizes from being sorted. The baffle plate 65 can prevent the screened particles from sliding out on both sides. When the crushing roller 54 squeezes the refractory castable to crush it, it will fall down onto the screening mesh 64 and be initially screened by gravity.

[0030] Then, when material needs to be retrieved, the operator can hold multiple push rods 63 on the side and pull them horizontally in sequence. The push rods 63 can drive the screening screen 64 to accelerate the discharge of blocked granules through the inertia of horizontal shaking. There are multiple material retrieval gates 4, and the inner side of the multiple material retrieval gates 4 is relatively connected to the space screened at the lower end of the screening screen 64. The material can be manually retrieved after the material retrieval gates 4 are opened. In this way, the screening screen of refractory castable is shaken by additional horizontal inertia, which reduces the situation of material blockage and directly screens the crushed refractory castable. The unnecessary spiral conveyor shaft mixing process is eliminated, which improves the production efficiency of the refractory castable production device.

[0031] The refractory castable mixing device 7 includes a positioning rod 71 and a housing 72. The positioning rod 71 is fixedly connected to the top side of the fixed plate 3. The positioning rod 71 can support the front end of the outer wall of the housing 72 by means of the upper flip shaft 73. An additional vertical column is set on the upper rear side of the fixed plate 3 to provide auxiliary support for the housing 72. The upper part of the positioning rod 71 is rotatably connected to the flip shaft 73. The refractory castable that has been crushed and screened and various additives, such as plasticizers, dispersants, accelerators, retarders, expansion agents, degelatinizers and gelling agents, can be put into the feeding hole 8 of the mixing tank 74 inside the housing 72.

[0032] The sleeve 72 is rotatably connected to the top of the tilting shaft 73. Multiple rotating bearings 75 are fixedly connected to the inner side of the sleeve 72. When mixing and stirring the refractory castable, the power supply is connected to start the first motor 77 at the lower end. The first motor 77 will drive the mixing tank 74 to rotate along the inner side of the sleeve 72 under the rotating bearings 75. The mixing tank 74 is rotatably connected inside the rotating bearings 75. The stirring wheel 76 is fixedly installed inside the mixing tank 74. When the mixing tank 74 rotates, it drives the refractory castable and additives inside to tumble and stir under the action of gravity. The stirring wheel 76 plays an auxiliary stirring function and is subjected to less force.

[0033] After the mixing is completed, the first motor 77 is turned off. The staff uses mechanical equipment to rotate the casing 72 along the tilting shaft 73 at a certain angle, so that the formed material inside the mixing tank 74 can be poured out. The first motor 77 is fixedly installed on the bottom outer wall of the casing 72. Both the second motor 53 and the first motor 77 are servo motors. When selecting the motor model, you can choose a motor model that meets the usage requirements. The output shaft of the first motor 77 passes through the casing 72 and is fixedly connected to the bottom of the mixing tank 74. The front end of the mixing tank 74 is fixedly provided with a feeding hole 8.

[0034] When mixing refractory castables, the power supply is connected and the first motor 77 at the lower end is started. The first motor 77 will drive the mixing tank 74 to rotate along the inner side of the casing 72 under the rotating bearing 75. When the mixing tank 74 rotates, the refractory castable and additives inside are turned and stirred by gravity. The stirring wheel 76 plays an auxiliary stirring function with less force. After the mixing is completed, the first motor 77 is turned off. The operator uses mechanical equipment to rotate the casing 72 along the tilting shaft 73 at a certain tilt angle, so that the molded material inside the mixing tank 74 can be poured out. The mixing tank rotation is used to achieve the mixing process of high-density and high-weight refractory castables. The mixing effect is better while reducing the force and wear on the stirring rod, thus reducing the cost of refractory castable production equipment.

[0035] Working principle:

[0036] The refractory castable production equipment is used for the production and processing of refractory castables. Refractory castables are mixtures of refractory aggregates, powders and binders. After adding water or other liquids, they are suitable for construction by pouring or vibration methods.

[0037] Screening and filtration structure of refractory castable production equipment:

[0038] The screening box 62 is used to screen and classify the crushed refractory castable according to the size of the aggregate particles. The limiting block 61 can support multiple screening plates 64 horizontally arranged inside the screening box 62. The screening mesh 64 is made of stainless steel metal mesh plate, and the aperture of the screening mesh 64 gradually decreases from top to bottom. This can prevent refractory castable particles of different sizes from being separated. The baffle plate 65 can prevent the screened particles from sliding out on both sides. After the refractory castable is crushed by the crushing roller 54 above, it will fall down onto the screening mesh 64 and be initially screened by gravity. Then, when it is necessary to pick up the material... At this time, the staff can hold the multiple push rods 63 on the side and pull and shake them horizontally in sequence. The push rods 63 can drive the screening screen 64 to accelerate the discharge of blocked granules through the inertia of horizontal shaking. There are multiple material picking doors 4. The inner side of the multiple material picking doors 4 is relatively connected to the space screened at the lower end of the screening screen 64. The material can be manually picked up after the material picking doors 4 are opened. In this way, the screening screen of refractory castable is shaken by additional horizontal inertia, which reduces the situation of material blockage and directly screens the crushed refractory castable, eliminating the unnecessary spiral conveyor shaft mixing process.

[0039] The mixing and stirring production structure of the refractory castable production unit:

[0040] The positioning rod 71 supports the front end of the outer wall of the casing 72 using the upper flip shaft 73. An additional vertical column is set on the rear side above the fixing plate 3 to provide auxiliary support for the casing 72. The feeding hole 8 of the mixing tank 74 inside the casing 72 can be used to put in crushed and screened refractory castable and various additives, such as plasticizers, dispersants, accelerators, retarders, expansion agents, degumming-gelling agents, etc. When mixing and stirring the refractory castable, the power supply is connected and the lower first motor 77 is started. The first motor 77 will drive the mixing tank 74 to rotate along the inner side of the casing 72 under the bearing 75. When the mixing tank 74 rotates, it drives the refractory castable and additives inside to tumble and stir under the action of gravity. The stirring wheel 76 plays an auxiliary stirring function with less force. After the stirring is completed, the first motor 77 is turned off. The operator uses mechanical equipment to rotate the casing 72 along the flip shaft 73 at a certain tilt angle, so that the formed material inside the mixing tank 74 can be poured out.

[0041] Example 2:

[0042] Please see Figure 1-6 In this embodiment, a refractory castable production device further includes a refractory castable extrusion and crushing structure 5, which includes a feed pipe 51 and a discharge valve 55. The feed pipe 51 is fixedly connected to the top of the crushing box 2. The feed pipe 51 is used to put large pieces of refractory castable that need to be crushed into the crushing box 2. Two second motors 53 are fixedly connected to the outside of the crushing box 2.

[0043] Crushing rollers 54 are fixedly installed at the output shaft ends of the two second motors 53. When the power is connected and the second motors 53 are started, the second motors 53 can drive the two opposing crushing rollers 54 on the inner side to rotate. The two crushing rollers 54 will crush the falling refractory castable. Finally, the discharge valve 55 is opened to let the crushed refractory castable powder fall into the screening box 62 below. The discharge valve 55 is fixedly connected to the lower end of the crushing box 2. The lower end of the discharge valve 55 is connected to the inner side of the screening box 62. The discharge valve 55 can be a conventional solenoid valve. The inside of the crushing box 2 is fixedly provided with a feeding trough 52.
