Description

Technical Field

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

[0002] Wear-resistant castable preparation equipment is a key piece of equipment used to produce high-performance wear-resistant castables. The preparation equipment is usually composed of a preparation cylinder, a mixing mechanism, a crushing mechanism, a drive and control system, etc. Wear-resistant castable preparation equipment is widely used in metallurgy, coal, thermal power, chemical, cement and other industries.

[0003] For example, Chinese patent CN212790819U, entitled "A Rapid Casting Device for Refractory Castables," includes an L-shaped body. A feed inlet is located at the top of the L-shaped body. A horizontally placed feed plate is fixedly connected to the inner wall of the L-shaped body. A screening port is located on the feed plate. A baffle is fixedly connected to the feed plate. A first motor is fixedly connected to the bottom of the L-shaped body. A first stirring rod is fixedly connected to the output end of the first motor through the bottom side wall of the L-shaped body. Stirring blades are fixedly connected to both sides of the first stirring rod. A second motor is fixedly connected to the protruding side wall of the L-shaped body. A second stirring rod is fixedly connected to the output end of the second motor through the protruding side wall of the L-shaped body. Spiral stirring blades are fixedly connected to the second stirring rod. A discharge port is located on the protruding side wall of the L-shaped body. A valve is installed on the discharge port. A screening turntable is sleeved on the first stirring rod. The screening turntable has the same area as the feed plate. Multiple screening ports are opened at equal angles on the feed plate.

[0004] While the existing technologies can achieve the preparation of castables, in practical use, the mixing effect of raw materials is not good enough. Usually, the raw materials are mixed using a fixed mixing rack, which makes it easy for small particles to pass directly through the mixing rack, thus reducing the mixing quality of the raw materials. On the other hand, the weighing of raw materials is not convenient. Usually, the raw materials need to be weighed in a centralized manner before preparation, which means that pre-weighing is required before each pouring of raw materials, thus reducing the efficiency of raw material preparation. Therefore, they do not meet the current needs. In response, we propose a wear-resistant castable preparation device. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant castable preparation device to solve the problems mentioned in the background art, such as insufficient mixing effect of raw materials and inconvenient weighing of raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant castable preparation device, comprising a base, a preparation tank disposed above the center of the base, a tank cover disposed at the upper end of the preparation tank, a rotating rod disposed at the lower end of the tank cover, the rotating rod being rotatably connected to the tank cover, mounting frames fixedly disposed above and below the rotating rod, a plurality of mounting cavities disposed inside the mounting frames, the mounting cavities being equidistantly distributed and having an open structure, a stirring plate disposed inside the mounting cavity, the stirring plate slidingly engaging with the mounting cavity, the stirring plate being equidistantly distributed, a threaded hole disposed inside the mounting frame near the center of the mounting cavity, the threaded hole having a through structure, and through holes disposed above and below the stirring plate, the through holes corresponding to the threaded holes.

[0007] Preferably, the mounting bracket is provided with a bolt outside the threaded hole opening, one end of the bolt extends into the interior of the mounting bracket through the threaded hole, and the other end of the bolt passes through the agitator plate through the through hole.

[0008] Preferably, connecting seats are fixedly installed on both sides of the outside of the preparation tank, a pressure sensor is fixedly installed at the lower end of the connecting seat, a support frame is fixedly installed at the lower end of the pressure sensor, and the lower end of the support frame is fixedly connected to the base.

[0009] Preferably, a plurality of heating wires are provided inside the side wall of the preparation tank, and the heating wires are distributed at equal intervals. A temperature sensor is fixedly provided below the front end of the preparation tank, and the probe structure of the temperature sensor extends into the interior of the preparation tank.

[0010] Preferably, a drive motor is fixedly installed at the center of the upper end of the can lid, the output shaft of the drive motor extends to the bottom of the can lid and is fixedly connected to the rotating rod, and a feeding hopper is fixedly installed at the upper end of the can lid on the side of the drive motor, the feeding hopper being connected to the preparation tank.

[0011] Preferably, a control panel is fixedly installed on one side of the support frame, and the control panel is electrically connected to the pressure sensor, heating wire, temperature sensor and drive motor.

[0012] Preferably, a discharge pipe is fixedly installed at the center of the lower end of the preparation tank, the discharge pipe is connected to the preparation tank, and a valve is fixedly installed on the outside of the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can adjust the gap of the stirring plates by means of the mounting cavity and bolts. Before mixing the raw materials, the stirring plates are adjusted according to the actual raw material type. At this time, a suitable number of stirring plates are placed in the mounting cavity and the stirring plates are kept in an equidistant distribution. At this time, the through holes on the stirring plates correspond to the threaded holes on the mounting frame. Then the operator aligns the bolts with the opening of the threaded holes and rotates them so that one end of the bolt moves into the threaded hole until the bolt is moved to the appropriate position. At this time, the bolt passes through the through hole and the stirring plate is fixed. Then the stirring mechanism is placed in the mixing tank to improve the stirring effect of the raw materials.

[0015] (2) This utility model can weigh the raw materials by means of a pressure sensor and a connecting seat. Before mixing the raw materials, the weight data on the control panel is cleared to zero, and then the raw materials are added to the mixing tank through the feeding hopper. As the raw materials are added, the pressure sensor will change data due to the pressure of the connecting seat. At this time, the amount of raw materials added is displayed on the control panel in real time until the appropriate amount of raw materials is added. When adding other raw materials, the weight data on the control panel is cleared to zero before adding, thereby improving the accuracy of raw material addition.

[0016] (3) This utility model can heat the raw materials by means of a temperature sensor and a heating wire. When the raw materials are mixed, all kinds of raw materials are concentrated in the preparation tank. At this time, the heating wire is energized. When the current flows through the heating wire which has its own resistance, the heating wire will generate a certain amount of heat. At this time, the heat on the heating wire is transferred to the raw materials through the tank wall. During this process, the raw materials are continuously stirred. At the same time, the operator observes the value displayed on the temperature sensor until the raw materials are heated to a suitable temperature, which accelerates the hydration reaction of the raw materials. At the same time, heating can promote the discharge of air bubbles in the raw materials, reduce porosity, and thus improve the corrosion resistance of the wear-resistant layer.

[0024] Please see Figure 2 , Figure 3 and Figure 4 A rotating rod 13 is provided at the lower end of the can lid 7. The rotating rod 13 is rotatably connected to the can lid 7. Mounting brackets 14 are fixedly provided on the upper and lower sides of the rotating rod 13. The mounting brackets 14 have several mounting cavities 17 inside. The mounting cavities 17 are evenly distributed and have an open structure. A stirring plate 15 is provided inside the mounting cavity 17. The stirring plate 15 slides with the mounting cavity 17 and is evenly distributed. A threaded hole 19 is provided inside the mounting bracket 14 near the center of the mounting cavity 17. The threaded hole 19 has a through structure. Through holes 20 are provided on the upper and lower sides of the stirring plate 15. The through holes 20 correspond to the positions of the threaded holes 19. A bolt 16 is provided on the outside of the mounting bracket 14 at the opening of the threaded hole 19. One end of the bolt 16 extends into the interior of the mounting bracket 14 through the threaded hole 19, and the other end of the bolt 16 passes through the through hole 20 through the stirring plate 15, so as to fix the stirring plate 15 with the bolt 16.

[0025] Please see Figure 1 and Figure 2Both sides of the preparation tank 6 are fixedly equipped with connecting seats 5. A pressure sensor 4 is fixedly installed at the lower end of the connecting seat 5. A support frame 2 is fixedly installed at the lower end of the pressure sensor 4. The lower end of the support frame 2 is fixedly connected to the base 1, so as to facilitate the weighing of the added raw materials through the pressure sensor 4.

[0026] Please see Figure 1 , Figure 2 and Figure 3 The preparation tank 6 has several heating wires 18 arranged inside the side wall. The heating wires 18 are evenly distributed. A temperature sensor 10 is fixedly installed below the front end of the preparation tank 6. The probe structure of the temperature sensor 10 extends into the interior of the preparation tank 6 to facilitate heating of the raw materials through the heating wires 18.

[0027] Working principle: In use, first adjust the stirring plate 15 according to the actual type of raw material. Then, place an appropriate number of stirring plates 15 into the mounting cavity 17, ensuring that the stirring plates 15 are evenly distributed. At this time, the through holes 20 on the stirring plate 15 correspond to the threaded holes 19 on the mounting bracket 14. Then, the operator aligns the bolt 16 with the opening of the threaded hole 19 and rotates it, causing one end of the bolt 16 to move into the threaded hole 19 until the bolt 16 is moved to the appropriate position. At this time, the bolt 16 passes through the through hole 20 and passes through the stirring plate 15, completing the fixation of the stirring plate 15. Then, the weight data on the control panel 3 is zeroed. Then, the raw material is added to the preparation tank 6 through the feed hopper 9. The pressure sensor 4 changes data when subjected to pressure from the connector 5. At this time, the amount of raw material added is displayed on the control panel 3 in real time until the appropriate amount of raw material is added. The amount of raw material added has taken into account the weight loss after drying. When adding other raw materials, the weight data on the control panel 3 is reset to zero before adding. When mixing raw materials, the heating wire 18 is energized. When the current flows through the heating wire 18 which has its own resistance, the heating wire 18 will generate a certain amount of heat. At this time, the heat on the heating wire 18 is transferred to the raw material through the tank wall. During this process, the raw material is continuously stirred. At the same time, the operator observes the value displayed on the temperature sensor 10 until the raw material is heated to the appropriate temperature.
