Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to a mixing hopper for mixing montmorillonite raw materials. Background Technology

[0002] The hopper mixer is one of the pieces of equipment used in the production of solid dosage forms of pharmaceuticals to complete the mixing process. It is mainly used for mixing solid particles with powder, powder with particles, and powder with powder in the pharmaceutical industry. It is also suitable for the production process of powder materials in the food and fine chemical industries.

[0003] During the mixing process, a large amount of dust will float in the powder material. After the powder material is added, it is not easy to seal and cover it. As a result, the floating dust will affect the control environment and quality, and pose a safety hazard to the staff.

[0004] To address the aforementioned problems, this utility model document proposes a mixing hopper for mixing montmorillonite raw materials. Utility Model Content

[0005] This utility model provides a mixing hopper for mixing montmorillonite raw materials, which solves the shortcomings of the prior art. During the mixing process, a large amount of dust floats in the powder material, and it is not easy to seal and cover the powder material after adding it. As a result, the floating dust will affect the control environment and quality, and pose safety hazards to the workers.

[0006] This utility model provides the following technical solution:

[0007] A mixing hopper for mixing montmorillonite raw materials includes:

[0008] A mixing hopper frame, wherein a support frame is fixedly installed on the outside of the mixing hopper frame, and a trolley for supporting and placing the support frame is installed at the bottom of the support frame;

[0009] The bottom of the mixing hopper frame is connected to a screw conveyor. Two through holes are opened on the outer wall of one end of the screw conveyor. A material leveling frame is fixedly installed at the through holes on the outer wall of the screw conveyor.

[0010] The covering mechanism is installed on the mixing hopper frame to cover and protect the mixing hopper frame.

[0011] In one possible design, the cover mechanism includes a frame, a sealing cover, a sliding groove, a limiting block, a mounting groove, a spring, and a limiting opening block. The frame is fixedly disposed on the outside of the mixing hopper frame, the sealing cover is slidably connected to the top of the mixing hopper frame, and the sliding groove is opened inside the sealing cover to limit its sliding on the frame.

[0012] In one possible design, an abutment block is fixedly provided on one side of the inner wall of each of the slides, and multiple limiting blocks are fixedly provided on the frame to limit the abutment block when the sealing cover is closed. Multiple mounting slots are opened on the top side of the frame, and each spring is fixedly provided on the bottom side of the inner wall of the mounting slot. The limiting block is fixedly provided on the top of the spring to limit the abutment block when the sealing cover is opened.

[0013] In one possible design, a first motor is fixedly installed on one side of the mixing hopper frame. The output end of the first motor passes through one side of the mixing hopper frame and extends into the interior of the mixing hopper frame. A stirring shaft is fixedly installed on the output end of the first motor via a coupling. Multiple stirring rods are fixedly installed on the outer wall of the stirring shaft. The end of the stirring shaft away from the first motor is rotatably connected to the inner wall of one side of the mixing hopper frame. A second motor is fixedly installed at the bottom of the uniform material frame. The output end of the second motor passes through the bottom side of the uniform material frame and extends into the interior of the uniform material frame. A rotating cone is fixedly installed on the output end of the second motor via a coupling. Multiple stirring racks are fixedly installed on the outer wall of the rotating cone.

[0014] In one possible design, the bottom side of the material leveling frame has a discharge port, and the bottom side of the material leveling frame has a moving groove that communicates with the discharge port. A sealing plate is slidably connected inside the moving groove, and a sealing ring is provided on the inner wall of the sealing plate. An electric push rod is fixedly installed on the outer side of the material leveling frame, and the output end of the electric push rod is fixedly connected to one side of the sealing plate.

[0015] In one possible design, the top side of the trailer is hinged to four locking frames for securing the support frame. Each locking frame has two bolts running through its top side, and the top side of the trailer has multiple threaded holes for bolt thread connection.

[0016] In this application, during use, firstly, the mixing hopper frame is moved and supported by a trolley. Four locking frames are rotatably connected to the trolley via hinges. These locking frames can be bolted to the screw holes on the trolley to securely clamp and lock the support frame, ensuring the stability of the mixing hopper frame during operation. Next, the montmorillonite raw materials and powders to be mixed are put into the mixing hopper frame. Then, the first motor is started, and its output end drives the stirring shaft to rotate through a coupling. Multiple stirring rods are fixed on the stirring shaft. These stirring rods, as the stirring shaft rotates, thoroughly stir and mix the raw materials in the mixing hopper frame. After the mixing is completed in the mixing hopper frame, the raw materials enter the screw conveyor through the outlet at the bottom of the mixing hopper frame. The screw blades of the screw conveyor push the raw materials forward along its interior. At the same time, the material equalization frame fixed at the through hole on the outer wall of the screw conveyor further equalizes and disperses the raw materials. The output end of the second motor is used to drive the rotating cone to rotate through a coupling. Multiple stirring frames fixed on the rotating cone stir and equalize the raw materials, further ensuring the uniformity of the raw materials.

[0017] After the raw materials pass through the equalization frame, they can be discharged through the discharge port on the bottom side of the equalization frame. The opening and closing of the discharge port is controlled by a sealing plate controlled by an electric push rod. When discharge is required, the electric push rod pushes the sealing plate to slide along the moving groove, opening the discharge port. After discharge is completed, the electric push rod pulls the sealing plate back to its original position, closing the discharge port. The sealing ring on the inner wall of the sealing plate ensures the sealing of the discharge port and prevents raw material leakage. In addition, in order to cover and protect the mixing hopper frame and prevent raw material splashing and environmental pollution, the equipment is also equipped with a cover protection mechanism. The sealing cover is slidably connected to the frame through a sliding groove, which can be easily opened and closed. When the sealing cover is closed, the abutment block in the sliding groove cooperates with the limit block on the frame to close the sealing cover. The limiting mechanism ensures stability and allows the sealing cover to close to a certain degree of tightness, achieving a sealed coverage effect on the mixing hopper frame. This prevents a large amount of dust from floating during the mixing process, thus preventing the floating dust from affecting the control environment and quality, and avoiding safety hazards for workers. Simultaneously, when the sealing cover is open, the spring and limiting block in the mounting groove remain in a non-compressed state, thereby limiting the abutment block and preventing the sealing cover from accidentally slipping off when it opens. By pressing the limiting block, the spring force compresses it, allowing the sealing cover to slide off and be removed for easy cleaning, thus improving convenience.

[0018] In this utility model, the mixing hopper for mixing montmorillonite raw materials has a cover mechanism that allows the sealing cover to be closed to a certain degree of sealing, achieving the effect of sealing and covering the mixing hopper frame, and preventing a large amount of dust from floating in the powder material during the mixing process.

[0019] In this utility model, the mixing hopper for mixing montmorillonite raw materials, through the arrangement of a screw conveyor, a stirring rod, a uniform material frame and a stirring rack, can fully stir and mix the raw materials in the mixing hopper frame, and can further homogenize and disperse the raw materials, and further ensure the uniformity of the raw materials.

[0020] In this invention, the sealing cover can be closed to a certain degree of sealing, achieving the effect of sealing and covering the mixing hopper frame. This prevents a large amount of dust from floating in the powder material during the mixing process, thus preventing the floating dust from affecting the control environment and quality, and avoiding safety hazards to the workers.

Multiple mounting grooves 14 are opened on the top side of the frame 10. Each spring 15 is fixedly installed on the bottom side of the inner wall of the mounting groove 14. A limiting block 16 is fixedly installed on the top of the spring 15 to limit the abutment blocks when the sealing cover 11 is open. When the sealing cover 11 is closed, the abutment blocks in the slide groove 12 cooperate with the limiting blocks 13 on the frame 10 to limit the sealing cover 11, ensuring... To ensure its stability, the sealing cover 11 can be closed to a certain degree of sealing, achieving the effect of sealing and covering the mixing hopper frame 1. When the sealing cover 11 is opened, the spring 15 and the limiting block 16 in the mounting groove 14 will always be in a non-compressed state, which can limit the abutment block and prevent the sealing cover 11 from accidentally slipping off when it is opened. By pressing the limiting block 16, under the elastic force of the spring 15, the limiting block 16 can be driven into a compressed state. At this time, the sealing cover 11 can be slid off and disassembled, which is convenient for cleaning the sealing cover 11 and improves convenience.
