Description

Technical Field

[0001] This utility model relates to the field of preparation technology of bromhexine hydrochloride soluble powder, and in particular to an apparatus for preparing bromhexine hydrochloride soluble powder. Background Technology

[0002] Bromhexine hydrochloride soluble powder is a commonly used expectorant. Its preparation process usually includes multiple steps such as mixing, pulverizing, sieving, and remixing to ensure uniformity.

[0003] Traditional preparation processes typically involve mixing, crushing, and sieving in multiple steps. This means that preliminary mixing is first performed in a mixer, then the mixed material is transferred to a crusher for crushing, and finally sieved. During these multiple material transfers, powder leakage is very likely. Some equipment uses a design that connects the lifting mechanism of the hopper to the rotating mechanism that drives the material cylinder. This design usually means that the power component that drives the lifting of the hopper (such as a pneumatic or hydraulic cylinder) needs to be mounted on the rotating material cylinder support, rotating and lifting with the material cylinder. This increases the weight and moment of inertia of the rotating part, resulting in the rotating mechanism requiring greater driving power, high energy consumption, a high center of gravity, and poor operational stability. Utility Model Content

[0004] The purpose of this invention is to provide an apparatus for preparing bromhexine hydrochloride soluble powder in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for preparing bromhexine hydrochloride soluble powder, comprising a fixed frame, a V-shaped material cylinder at the upper end of the fixed frame, a valve at the bottom of the material cylinder, a rotating mechanism at the top of the fixed frame for driving the material cylinder to rotate around its axis, a hopper at the lower end of the fixed frame, a crushing mechanism at the bottom and inner cavity of the hopper, a connecting assembly at the outer side of the hopper, a cylinder connected to the connecting assembly at the bottom of the fixed frame, a motor three at the upper end of the hopper, a screen at the output end of the motor three extending into the hopper, and a buckle connecting the outer sides of the hopper and the material cylinder.

[0006] Preferably, the connecting assembly includes a semi-circular clamp one and a clamp two, both ends of which are equipped with side plates. One end of the side plates is hinged to each other, and the other end of the side plates is connected by a locking assembly. Support plates are installed on the outer ends of the side plates at both ends of the clamp one, and the bottom of the support plates is connected to the cylinder extension end.

[0007] Preferably, the locking assembly includes two rotating rods hinged to one side of the other end of the clamp two. The rotating rods are L-shaped, and a U-shaped rotating rod is hinged to one end of each of the two rotating rods. A handle is installed on one side of each rotating rod, and an insert rod is hinged to the inner side of each rotating rod. A limiting plate is also installed on one side of the other end of the clamp two, and a fixing plate is installed on one side of the other end of the clamp one. The end of the insert rod that passes through the limiting plate is pressed into contact with the fixing plate.

[0008] Preferably, the rotating mechanism includes a motor mounted on the upper end of the fixed frame, and both ends of the material cylinder are equipped with rotating shafts that are rotatably connected to the fixed frame, with one end of the rotating shaft connected to the output end of the motor.

[0009] Preferably, the crushing mechanism includes a second motor installed at the bottom of the hopper, the output end of the second motor extending into the hopper is connected to a vertical rod, and multiple blades are installed in an array on the outer side of the vertical rod.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] 1. In this application, the precise docking of the hopper and the cylinder is achieved by cylinder drive, and combined with the snap-locking, a completely sealed transmission channel is formed between the mixing and crushing stations. This eliminates the powder leakage problem caused by multiple material transfers in traditional step-by-step processes, which not only improves product yield, but also fundamentally avoids cross-contamination and environmental pollution, and significantly improves the operating environment.

[0012] 2. In this application, a split layout is set up, which completely decouples the rotating mechanism and the lifting mechanism (cylinder) in terms of mechanical structure. This makes the rotating mechanism that drives the material cylinder to rotate only include the material cylinder itself and its rotating shaft. Its total mass and volume are greatly reduced. The reduction of rotating mass directly leads to a significant reduction in its moment of inertia, resulting in higher stability and reliability. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 This utility model provides a technical solution: a preparation device for soluble bromhexine hydrochloride powder, including a fixed frame 1, a V-shaped material cylinder 2 at the upper end of the fixed frame 1, a valve 3 at the bottom of the material cylinder 2, a rotating mechanism 4 at the top of the fixed frame 1 for driving the material cylinder 2 to rotate around its axis, a material bin 5 at the lower end of the fixed frame 1, a crushing mechanism 6 at the bottom and inner cavity of the material bin 5, a connecting component 7 on the outer side of the material bin 5, a cylinder 8 connected to the connecting component 7 at the bottom end of the fixed frame 1, a motor 9 at the upper end of the material bin 5, a screen 901 at the output end of the motor 9 extending into the material bin 5, and a buckle 10 connecting the outer side of the material bin 5 and the material cylinder 2.

[0024] The fixing frame 1 is welded from shaped steel (such as square tubes or angle steel) and serves as the main support for the entire device, providing the mounting base for all functional components. The V-shaped shape of the material cylinder 2, when rotated around its axis, causes strong convection, shearing, and diffusion motion of the material inside the cylinder, resulting in a mixing efficiency far higher than that of ordinary cylinders. In this embodiment, the valve 3 is preferably a pneumatic or electric butterfly valve or ball valve, which can achieve automatic opening and closing control. A manual slide gate valve can also be used. The rotating mechanism 4 is used to drive the material cylinder 2 to perform mixing motion. The hopper 5 is roughly inverted conical or cylindrical in shape, with an open top to receive material falling from the material cylinder 2. The connecting assembly 7 is used to achieve quick installation and fixation of the hopper 5. And connected to the lifting power, the core function is to clamp the outer wall of the hopper 5 in a quick-opening and closing manner, and effectively transmit the thrust of the lifting cylinder 8 to the hopper 5. The extension and retraction of the cylinder 8 can drive the entire hopper 5 assembly to rise or fall vertically. When the screen 901 is poured from the cylinder 2 into the hopper 5, the motor 9 needs to be started to rotate to a vertical state. When the screen 901 is poured from the hopper 5 into the cylinder 2, it needs to be rotated to block the top of the hopper 5. Powder of qualified particle size falls into the cylinder 2 through the screen 901, which is used to control the particle size of the crushed material. The latch 10 (such as quick clamp, butterfly nut latch, etc.) can provide additional clamping force to ensure the sealing of the joint and prevent powder leakage.

[0025] Specifically, such as Figure 2 As shown, the connecting component 7 includes a semi-circular clamp 1 701 and a clamp 2 702. Both ends of the clamp 1 701 and the clamp 2 702 are equipped with side plates 703. One side plate 703 is hinged to the other side plate, and the other side plate 703 is connected by a locking component 704. Support plates 705 are installed on the outer ends of the side plates 703 at both ends of the clamp 1 701. The bottom of the support plate 705 is connected to the telescopic end of the cylinder 8.

[0026] The side plates 703 are hinged together, allowing clamp 1 701 and clamp 2 702 to open and close like a book. The locking component 704 acts as a "switch" for the connecting component 7. The two support plates 705 are symmetrically arranged and form a two-point hinge with the cylinder 8, ensuring that the lifting force is evenly applied to clamp 1 701, thereby preventing the hopper 5 from tilting or jamming during the lifting process.

[0027] Specifically, such as Figure 3As shown, the locking assembly 704 includes two rotating rods 11 hinged to one side of the other end plate 703 of the clamp 2 702. The rotating rods 11 are L-shaped. One end of the two rotating rods 11 is hinged to a U-shaped rotating rod 12. A handle 16 is installed on one side of the rotating rod 12. An insert rod 13 is hinged to the inner side of the rotating rod 12. A limiting plate 14 is also installed on one side of the other end plate 703 of the clamp 2 702. A fixing plate 15 is installed on one side of the other end plate 703 of the clamp 1 701. One end of the insert rod 13 passes through the limiting plate 14 and is pressed into contact with the fixing plate 15.

[0028] When the handle 16 is pulled down, the operating force is amplified and converted into a horizontal thrust of the insertion rod 13 toward the fixed plate 15 through the composite lever system consisting of the L-shaped rotating rod 11 and the U-shaped rotating rod 12. After the insertion rod 13 passes through the limiting plate 14, it presses tightly against the fixed plate 15, thereby generating a huge locking force and firmly locking the two clamps together.

[0029] Specifically, such as Figure 4 As shown, the rotating mechanism 4 includes a motor 401 mounted on the upper end of the fixed frame 1, and rotating shafts 402 that are rotatably connected to the fixed frame 1 are mounted on both ends of the material cylinder 2. One end of the rotating shaft 402 is connected to the output end of the motor 401.

[0030] Motor 401 is preferably a geared motor (or geared motor), which is firmly mounted on a specially designed motor mounting plate on top of the fixed frame 1 with anchor bolts. The reason for choosing a geared motor is that it integrates a motor and a reducer, and can directly output a lower speed and a larger torque, which is perfectly suited to the working conditions required for mixing materials in the material cylinder 2. There is no need to configure an additional complex transmission system, making the structure very compact. The selected power of motor 401 needs to be calculated and determined according to the capacity and maximum loading amount of the material cylinder 2 to ensure that it can provide sufficient starting and running torque. The rotating shafts 402 at both ends are rotatably connected to the fixed frame 1 through mounted bearings (or bearing housings). A mounted bearing is a standard part that integrates a rolling bearing and a bearing housing. It is fixed to the fixed frame 1 with bolts, providing stable and reliable support for the rotating shafts 402 and effectively bearing radial loads. Its sealing structure can prevent dust from entering the bearing and extend its service life.

[0031] Specifically, such as Figure 5 As shown, the crushing mechanism 6 includes a second motor 601 installed at the bottom of the hopper 5. The output end of the second motor 601 extends into the hopper 5 and is connected to a vertical rod 602. Multiple blades 603 are installed in an array on the outer side of the vertical rod 602.

[0032] Motor 2 601 is a high-power, high-speed motor, typically a three-phase asynchronous motor or a series-wound motor, to provide sufficient grinding linear velocity. It is vertically bolted and flange-mounted to the center of the bottom of hopper 5. High-performance mechanical seals or oil seals are installed between the flange and the bottom cover of hopper 5, and at the location where the output shaft of motor 2 601 passes through the bottom cover. This sealing structure effectively prevents powder from hopper 5 from entering the interior of motor 2 601 or leaking into the environment, ensuring the reliability and safety of the equipment operation. Blade 603 can be designed in different shapes (such as hammer type or turbine type) to optimize grinding. The motor 601 drives the upright 602 to rotate at high speed, which in turn drives the blades 603 to impact, shear, and grind the material. The upright 602 is a vertically installed rigid shaft, which serves as the main shaft of the entire crushing disc. Its length is determined according to the height of the hopper 5. It is necessary to ensure that the blades 603 at the top of the upright 602 can effectively act on the material near the screen 901. The upper end of the upright 602 can be rotatably connected to the top cover of the hopper 5 or an additional support beam through a deep groove ball bearing. This can greatly improve the stability of the upright 602 when rotating at high speed, reduce vibration and sway, and extend the life of the mechanical seal and bearings.

[0033] In summary, the apparatus for preparing bromhexine hydrochloride soluble powder provided in this embodiment is used as follows:

[0034] Loading and initial mixing: Start motor 401, drive rotating shaft 402 and rotate material cylinder 2 180 degrees and then stop. This operation changes the valve 3 at the bottom of material cylinder 2 from downward to upward, making it easier to add materials manually or mechanically from above. Open valve 3 and put various raw materials into material cylinder 2. Then close valve 3 and start motor 401 again to drive material cylinder 2 to continue rotating. Utilizing the characteristics of V-shaped material cylinder 2, the material is fully convection, shearing and diffusion in the cylinder to achieve initial mixing. After completion, stop motor 401.

[0035] Unloading into the hopper and crushing: Control motor 1 401 to rotate the cylinder so that its valve 3 is directly above the lower hopper 5. Start motor 3 9 to drive the screen 901 to rotate to a vertical state (i.e., open state, forming an open inlet). Start cylinder 8 to push the entire hopper 5 upward through connecting component 7 until its top is tightly fitted with valve 3 at the bottom of cylinder 2. Open valve 3, and the preliminarily mixed material falls into hopper 5. Start motor 2 601 to drive the upright 602 and blade 603 to rotate at high speed to crush and grind any lumps that may exist in the material.

[0036] Preparation for backfilling: Restart motor 39 to drive screen 901 to rotate to a horizontal position, close the top opening of hopper 5, open locking component 704, release clamps 701 and 702 from the outer wall of hopper 5, operate buckle 10 to firmly fix the upper end of hopper 5 to the outer side of cylinder 2. At this time, hopper 5 and cylinder 2 change from a separate state that can be raised and lowered to a whole that can rotate synchronously. Cylinder 8 retracts, causing connecting component 7 to descend and reset, detaching from hopper 5.

[0037] Overall Tilting and Screening: Start motor 401 to drive the material cylinder 2 and the hopper 5 to rotate 180 degrees together. This operation causes the hopper to rotate from bottom to top, and the material inside falls onto the screen 901, which has become the bottom, under the action of gravity. At the same time or after the tilting, motor 601 can be started again, and the rotating blades 603 will throw the material onto the screen 901, which will also play a role in crushing and pushing. Powder with qualified particle size falls into the material cylinder 2 below through the holes of the screen 901, while larger particles are trapped in the material 5 and continue to be crushed by the blades 603 until they can pass through the screen 901. The powder screened back to the material cylinder 2 has a uniform particle size. At this time, the material cylinder 2 can be kept rotating to allow the material to undergo the final stage of homogenization and mixing in the material cylinder 2, so as to obtain a high-quality bromhexine hydrochloride soluble powder product.
