Description

Technical Field

[0001] This utility model belongs to the field of steel fiber castable mixing technology, and particularly relates to a modified and improved steel fiber castable mixing device. Background Technology

[0002] The steel fiber castable mixing device is a special mixing equipment used to uniformly disperse steel fibers with refractory aggregates, powders and binders. Its core function is to solve the problems of easy agglomeration, sedimentation and damage of steel fibers by optimizing the mixing structure (such as layered and zoned design, flexible blades or airflow assistance), so as to ensure that the fibers are uniformly distributed in three dimensions in the castable, thereby improving the crack resistance, toughness and high temperature performance of the material.

[0003] For example, Chinese patent CN222792417U discloses a mixing device for nano-ceramic spraying and casting refractory. It includes a substrate, a support assembly below the substrate, a mixing cylinder fixedly mounted on the upper surface of the substrate, a mixing assembly inside the mixing cylinder, a driving device for rotating the mixing assembly fixedly mounted on the lower surface of the substrate, an extension plate fixedly mounted on the right side wall of the substrate, a water tank fixedly mounted on the upper surface of the extension plate, a water pump inside the water tank, a water guide pipe connected to the upper end of the water tank, and a water guide assembly mounted on the upper side wall of the mixing cylinder. This invention uses a rotating shaft to drive the first, second, and third crossbars to rotate. Because the lengths of the first, second, and third crossbars are different, uniform mixing of the nano-ceramic spraying and casting refractory can be achieved, completing the mixing of the nano-ceramic spraying and casting refractory in one step, greatly reducing rework and improving work efficiency.

[0004] The above-mentioned patent has the following problems: In actual use, it does not have the function of collecting dust. Due to the hard texture of steel fibers, they are prone to generating fine fiber particles when they collide with the blades and cavity walls during the mixing process. These particles are then released with the airflow to form dust. The dust not only pollutes the workshop environment but may also harm the health of the operators (long-term inhalation of steel fibers may cause respiratory damage), which is not conducive to the use of the equipment by the staff. In view of this, we propose a modified and improved steel fiber castable mixing device. Utility Model Content

[0005] The purpose of this invention is to provide a device for mixing modified and improved steel fiber castables to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a mixing device for modified and enhanced steel fiber castable, comprising:

[0007] The box body has a first rotating shaft rotatably mounted on its top, which extends into the interior of the box body. The bottom of the first rotating shaft is rotatably mounted on the bottom of the inner wall of the box body. Two symmetrically distributed first stirring rods are fixedly connected to the outside of the first rotating shaft, and multiple circumferentially distributed second stirring rods are fixedly connected to the outside of the first rotating shaft.

[0008] Two collection boxes are fixedly connected to the top of the box body. A second rotating shaft is rotatably installed on one side of each of the two collection boxes. One end of each of the two second rotating shafts passes through the interior of the two collection boxes. Multiple circumferentially distributed air intake fan blades are fixedly connected to the exterior of each of the two collection boxes. Air ducts are connected to both sides of each of the two collection boxes. The other end of each of the two air ducts is connected to the top of the box body.

[0009] A first rotating assembly is disposed outside the first rotating shaft and is used to drive the first rotating shaft to rotate.

[0010] The second rotating assembly is disposed outside the two second rotating shafts and is used to drive the two second rotating shafts to rotate simultaneously.

[0011] In this technical solution, the raw material is conveyed into the interior of the box through the feed pipe. The first rotating component can be activated by starting the motor to drive the first rotating shaft to rotate. The rotation of the first rotating shaft drives the two first stirring rods to move in a circle around the first rotating shaft, and drives multiple second stirring rods to move in a circle around the first rotating shaft. Through the circular motion of the first and second stirring rods, the steel fiber castable can be mixed. The mixed steel fiber castable can be taken out from the interior of the box through the discharge pipe. The opening and closing of the feed pipe and the discharge pipe can be controlled by the solenoid valves set outside the feed pipe and the discharge pipe. Through the above structure, the steel fiber castable can be mixed.

[0012] The second rotating component drives the suction fan blades to rotate around the second rotating shaft, generating suction inside the collection box. This suction draws the dust generated during mixing into the collection box through the air duct. The filter plate prevents dust from contacting the suction fan blades and damaging them. This structure effectively collects fine fiber particles generated during mixing by the collision of raw materials with the first and second mixing rods. This prevents the fiber particles from escaping with the airflow and forming dust, which could pollute the workshop environment and harm the health of operators, thus making the equipment more convenient for workers to use.

[0013] In the above technical solution, further, a feed pipe is connected to one side of the box body, and a discharge pipe is connected to one side of the box body. Solenoid valves are provided on the outside of both the feed pipe and the discharge pipe.

[0014] In this technical solution, raw materials can be conveyed through the set discharge pipe and feed pipe, and the opening or closing of the feed pipe and discharge pipe can be controlled by the solenoid valve set outside the feed pipe and discharge pipe.

[0015] In the above technical solution, the first rotating component further includes a motor, which is disposed on the top of the housing. The output end of the motor is rotatably mounted on the top of the housing. A drive gear is fixedly sleeved on the output end of the motor. A driven gear is fixedly sleeved on the outside of the first rotating shaft. The drive gear and the driven gear are meshed together.

[0016] In this technical solution, since the driving gear and the driven gear are meshed together, the rotation of the driving gear can drive the driven gear and the first rotating shaft to rotate.

[0017] In the above technical solution, a support frame is fixedly connected to the top of the housing, and the motor is fixedly mounted on the support frame.

[0018] In this technical solution, the support frame ensures that the motor will not idle during operation.

[0019] In the above technical solution, the second rotating component further includes a first bevel gear, which is fixedly connected to the top of the first rotating shaft, and a second bevel gear is fixedly connected to one end of each of the two second rotating shafts, with the first bevel gear meshing with the two second bevel gears.

[0020] In this technical solution, since the first bevel gear is meshed with the two second bevel gears, the rotation of the first bevel gear can drive the two second bevel gears and the two second rotating shafts to rotate.

[0021] In the above technical solution, furthermore, each of the two collection boxes has multiple equally spaced ventilation holes on one side.

[0022] In this technical solution, multiple ventilation holes are provided to allow air circulation inside the collection box.

[0023] Furthermore, in the above technical solution, filter plates are fixedly connected inside both collection boxes.

[0024] In this technical solution, the filter plate prevents dust from coming into contact with the intake fan blades and causing damage to them.

[0025] The beneficial effects of this utility model are:

[0026] The raw materials are fed into the chamber through the feed pipe. The first rotating component, when activated by a motor, drives the first rotating shaft to rotate. This rotation causes two first stirring rods and multiple second stirring rods to move around the shaft. The circular motion of the first and second stirring rods mixes the steel fiber castable. The mixed steel fiber castable is then removed from the chamber through the discharge pipe. The feed and discharge pipes are opened and closed by solenoid valves located outside them. This structure allows for the mixing of the steel fiber castable.

[0027] The second rotating component drives the suction fan blades to rotate around the second rotating shaft, generating suction inside the collection box. This suction draws the dust generated during mixing into the collection box through the air duct. The filter plate prevents dust from contacting the suction fan blades and damaging them. This structure effectively collects fine fiber particles generated during mixing by the collision of raw materials with the first and second mixing rods. This prevents the fiber particles from escaping with the airflow and forming dust, which could pollute the workshop environment and harm the health of operators, thus making the equipment more convenient for workers to use.

[0036] Example 1: This example provides a mixing device for modified and enhanced steel fiber castable, comprising:

[0037] Box 1, with a first rotating shaft 8 rotatably mounted on the top of the box 1, the first rotating shaft 8 extending into the interior of the box 1, the bottom of the first rotating shaft 8 rotatably mounted on the bottom of the inner wall of the box 1, two symmetrically distributed first stirring rods 10 fixedly connected to the outside of the first rotating shaft 8, and multiple circumferentially distributed second stirring rods 11 fixedly connected to the outside of the first rotating shaft 8.

[0038] Two collection boxes 13 are fixedly connected to the top of the box body 1. A second rotating shaft 14 is rotatably installed on one side of each of the two collection boxes 13. One end of each of the two second rotating shafts 14 passes through the interior of the two collection boxes 13. Multiple circumferentially distributed suction fan blades 16 are fixedly connected to the exterior of each of the two collection boxes 13. Air ducts 19 are connected to both sides of each of the two collection boxes 13. The other end of each of the two air ducts 19 is connected to the top of the box body 1.

[0039] The first rotating assembly is disposed outside the first rotating shaft 8 and is used to drive the first rotating shaft 8 to rotate.

[0040] The second rotating assembly is disposed outside the two second rotating shafts 14 and is used to drive the two second rotating shafts 14 to rotate simultaneously.

[0041] The raw materials are conveyed into the interior of the housing 1 through the feed pipe 2. The first rotating component can drive the first rotating shaft 8 to rotate by the starter motor 6. The rotation of the first rotating shaft 8 drives the two first stirring rods 10 to move around the first rotating shaft 8 in a circular motion, and drives the multiple second stirring rods 11 to move around the first rotating shaft 8 in a circular motion. Through the circular motion of the first stirring rods 10 and the second stirring rods 11, the steel fiber castable can be mixed. The mixed steel fiber castable can be taken out from the interior of the housing 1 through the discharge pipe 3. The opening or closing of the feed pipe 2 and the discharge pipe 3 can be controlled by the solenoid valve 4 set outside the feed pipe 2 and the discharge pipe 3. Through the above structure, the steel fiber castable can be mixed.

[0042] The second rotating component drives the suction fan blade 16 to rotate around the second rotating shaft 14, which generates suction inside the collection box 13. This suction draws the dust generated during mixing into the collection box 13 through the air duct 19. The filter plate 17 prevents dust from contacting the suction fan blade 16 and damaging it. This structure collects fine fiber particles that are easily generated by the collision between the raw materials and the first and second stirring rods 10 and 11 during mixing. This prevents the fiber particles from escaping with the airflow and forming dust, which would pollute the workshop environment and harm the health of the operators, thus making it more convenient for the operators to use.

[0043] Example 2: This example provides a modified and improved steel fiber castable mixing device. In addition to the technical solutions of the above examples, it also has the following technical features: a feed pipe 2 is connected to one side of the box body 1, a discharge pipe 3 is connected to one side of the box body 1, and a solenoid valve 4 is provided on the outside of both the feed pipe 2 and the discharge pipe 3.

[0044] The raw materials can be transported through the discharge pipe 3 and the feed pipe 2. The feed pipe 2 and the discharge pipe 3 can be opened or closed by the solenoid valve 4 set outside the feed pipe 2 and the discharge pipe 3.

[0045] Example 3: This example provides a modified and improved steel fiber castable mixing device. In addition to the technical solutions of the above examples, it also has the following technical features: the first rotating component includes a motor 6, which is disposed on the top of the housing 1. The output end of the motor 6 is rotatably mounted on the top of the housing 1. The output end of the motor 6 is fixedly sleeved with a drive gear 7. The external side of the first rotating shaft 8 is fixedly sleeved with a driven gear 9. The drive gear 7 and the driven gear 9 are meshed and connected.

[0046] Since the driving gear 7 and the driven gear 9 are meshed together, the rotation of the driving gear 7 can drive the driven gear 9 and the first rotating shaft 8 to rotate.

[0047] Example 4: This example provides a modified and improved steel fiber castable mixing device. In addition to the technical solutions of the above examples, it also has the following technical features: a support frame 5 is fixedly connected to the top of the box 1, and a motor 6 is fixedly installed on the support frame 5.

[0048] The support frame 5 ensures that the motor 6 will not idle during operation.

[0049] Example 5: This example provides a modified and improved steel fiber castable mixing device. In addition to the technical solutions of the above examples, it also has the following technical features: the second rotating component includes a first bevel gear 12, which is fixedly connected to the top of the first rotating shaft 8. One end of each of the two second rotating shafts 14 is fixedly connected to a second bevel gear 15, and the first bevel gear 12 is meshed with the two second bevel gears 15.

[0050] Since the first bevel gear 12 is meshed with the two second bevel gears 15, the rotation of the first bevel gear 12 can drive the two second bevel gears 15 and the two second rotating shafts 14 to rotate.

[0051] Example 6: This example provides a modified and enhanced steel fiber castable mixing device. In addition to the technical solutions of the above examples, it also has the following technical features: multiple equidistant ventilation holes 18 are provided on one side of each of the two collection boxes 13.

[0052] The multiple ventilation holes 18 allow air to circulate inside the collection box 13.

[0053] Example 7: This example provides a modified and improved steel fiber castable mixing device. In addition to the technical solutions of the above examples, it also has the following technical features: filter plates 17 are fixedly connected inside both collection boxes 13.

[0054] The filter plate 17 prevents dust from coming into contact with the intake fan blades 16 and causing damage to them.

[0055] Working principle: When it is necessary to mix the steel fiber castable, the raw material is first transported into the interior of the housing 1 through the feed pipe 2. The motor 6 is started, and the output end of the motor 6 drives the drive gear 7 to rotate. Since the drive gear 7 and the driven gear 9 are meshed, the rotation of the drive gear 7 drives the driven gear 9 and the first rotating shaft 8 to rotate. The rotation of the first rotating shaft 8 drives the two first stirring rods 10 to move around the first rotating shaft 8 in a circle, and drives the multiple second stirring rods 11 to move around the first rotating shaft 8 in a circle. Through the circular motion of the first stirring rods 10 and the second stirring rods 11, the steel fiber castable can be mixed. The mixed steel fiber castable can be taken out from the interior of the housing 1 through the discharge pipe 3. The solenoid valve 4 set outside the feed pipe 2 and the discharge pipe 3 can control the opening or closing of the feed pipe 2 and the discharge pipe 3. Through the above structure, the steel fiber castable can be mixed.

[0056] The rotation of the first rotating shaft 8 drives the first bevel gear 12 to rotate. Since the first bevel gear 12 is meshed with the two second bevel gears 15, the rotation of the first bevel gear 12 drives the two second bevel gears 15 and the two second rotating shafts 14 to rotate. Subsequently, the suction fan blades 16 rotate around the second rotating shafts 14, which generates suction inside the collection box 13. This allows the dust generated during the stirring process to be sucked into the collection box 13 through the air duct 19. The filter plate 17 prevents the dust from contacting the suction fan blades 16 and damaging them. Through the above structure, the fine fiber particles that are easily generated by the collision between the raw materials and the first stirring rod 10 and the second stirring rod 11 during the stirring process can be collected. This avoids the disadvantages of fiber particles escaping with the airflow and forming dust, polluting the workshop environment, and harming the health of the operators, thus making it more convenient for the operators to use.
