Description

Technical Field

[0001] This utility model relates to the field of vitamin D3 powder production and processing technology, specifically a device that can improve the material flowability of vitamin D3 powder. Background Technology

[0002] Vitamin D3 powder is a form of vitamin D3 supplement produced through ultraviolet radiation or chemical synthesis. It is commonly used for food fortification, dietary supplementation, or nutritional intervention for specific populations. Its core functions include promoting calcium absorption, maintaining bone health, and regulating immunity. It is suitable for people with insufficient sun exposure, low dietary intake, or absorption disorders. During the production and processing of vitamin D3 powder, after spray drying in a centrifugal spray granulator, the powder needs to pass through a material pipeline approximately 8 meters long, including two 90° turns and a 0.8-meter elevation gain section, before entering a vibrating screen for powder collection and sieving.

[0003] During the conveying process of vitamin D3 powder from spray drying to powder collection and sieving, material accumulation and blockage are highly likely to occur at the second 90° turn in the material pipeline, severely affecting the normal conveying of vitamin D3 powder. Currently, the solution is to have a dedicated person use a wooden hammer to tap the outer wall of the pipeline to promote normal material flow. However, the timing and force of the tapping both rely on the operator's experience, resulting in high labor costs, a large workload, and hindering precise control of automated conveying. Utility Model Content

[0004] The purpose of this invention is to overcome the defects and deficiencies of the existing technology and provide a device that can improve the flowability of vitamin D3 powder during conveying. In addition, it facilitates the precise control of automated conveying of vitamin D3 powder and replaces manual operation, thereby saving labor costs and reducing workload.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An apparatus for improving the flowability of vitamin D3 powder materials includes a centrifugal spray granulation dryer for spray drying vitamin D3 powder, a vibrating screen for sieving vitamin D3 powder, and a material pipeline connected between the two. The material pipeline includes a corner pipe section and a lifting pipe section connected in sequence. The apparatus is characterized in that a striking mechanism is provided on one side of the connection between the corner pipe section and the lifting pipe. The striking mechanism can reciprocate and is used to strike the pipe wall at the connection between the corner pipe section and the lifting pipe.

[0006] Furthermore, the striking mechanism includes a pendulum and a drive component for driving the pendulum to reciprocate.

[0007] Furthermore, the drive component includes a motor, a speed reducer, and a frequency converter for controlling the motor to rotate forward and backward. The input shaft of the speed reducer is connected to the output shaft of the motor, and a sleeve is fixedly connected to the output shaft of the speed reducer.

[0008] Furthermore, the pendulum includes a hammer head and a hammer handle, with the hammer handle fixedly fitted into the sleeve.

[0009] Furthermore, the hammerhead is made of wood or rubber.

[0010] Furthermore, the motor, reducer, and frequency converter are all mounted on the same platform, which is fixed to the material tank below by support columns.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention features a striking mechanism installed at the connection between the corner pipe section and the lifting pipe, specifically on one side of the second 90° corner of the material pipeline. This striking mechanism can reciprocate and swing to strike the pipe wall at the connection between the corner pipe section and the lifting pipe. The frequency of its reciprocating swing and striking is controlled by a frequency converter. This effectively improves the flowability of vitamin D3 powder during the conveying and lifting process, facilitates precise control of automated conveying of vitamin D3 powder, replaces manual operation, saves labor costs, and reduces workload.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] See Figure 1 , 2An apparatus for improving the flowability of vitamin D3 powder materials includes a centrifugal spray granulation dryer 1 for spray drying vitamin D3 powder, a vibrating screen 2 for sieving vitamin D3 powder, and a material pipeline 3 connected between the two. The material pipeline 3 includes a corner pipe section 31 and a lifting pipe section 32 connected in sequence. A striking mechanism 4 is provided on one side of the connection between the corner pipe section 31 and the lifting pipe section 32, that is, at the second 90° corner of the material pipeline 3. The striking mechanism 4 can reciprocate and swing to strike the pipe wall at the connection between the corner pipe section 31 and the lifting pipe section 32, that is, the pipe wall at the second 90° corner of the material pipeline 3.

[0016] In this invention, the striking mechanism 4 includes a pendulum 41 and a driving component for driving the pendulum to reciprocate.

[0017] Specifically, the drive components include a motor 42, a reducer 43, and a frequency converter 44 for controlling the forward and reverse rotation of the motor 42. The input shaft of the reducer 43 is connected to the output shaft of the motor 42, and a sleeve 45 is fixedly connected to the output shaft of the reducer 43.

[0018] Furthermore, the pendulum 41 includes a hammer head 411 and a hammer handle 412. The hammer handle 412 is fixedly fitted into the sleeve 411 to connect the pendulum 41 and drive it to perform reciprocating swing.

[0019] Furthermore, the hammer 411 is made of wood or rubber, which can strike the pipe wall at the connection between the corner pipe section 31 and the lifting pipe 32 without causing damage.

[0020] In this utility model, the motor 42, the reducer 43 and the frequency converter 44 are all installed on the same platform 5. The platform 5 is fixed to the material tank 7 below by the support column 6, so as to realize the installation of the motor 42, the reducer 43 and the frequency converter 44.

[0021] The present invention will be further described below with reference to the accompanying drawings: In use, the motor 42 drives the pendulum 41 to swing back and forth through the reducer 43. The hammer head 411 strikes the pipe wall at the connection between the corner pipe section 31 and the lifting pipe 32 at a set frequency, that is, strikes the pipe wall at the second 90° corner of the material pipe 3.

[0022] Specifically, motor 42 is a three-phase asynchronous motor that can rotate in both directions, and its power is 0.75KW.

[0023] The frequency converter 44 uses the Siemens MM440 frequency converter.

[0024] The specific steps and parameter settings for connecting and controlling the Siemens MM440 frequency converter 44 and the three-phase asynchronous motor 42 are as follows: 1. Wiring method (1) Main circuit wiring: The input terminals (R, S, T) of the frequency converter are connected to a three-phase power supply.

[0025] The output terminals (U, V, W) of the frequency converter are connected to the corresponding terminals of the three-phase asynchronous motor.

[0026] (2) Wiring of the control circuit: Digital input terminals (e.g., 5, 6, 7, 8, 9): used for start / stop control, multi-speed control, etc. For example, terminals 5 and 9 can be used for remote start / stop control, and terminals 6, 7, and 8 can be used for multi-speed control.

[0027] Analog input terminals (such as 3, 4 or 10, 11): used to receive analog signals (such as 0-10V voltage or 4-20mA current output from a potentiometer) to adjust the frequency.

[0028] Analog output terminals (such as 12, 13 or 26, 27): can output 0-20mA current signals for monitoring inverter status (such as frequency, current, etc.).

[0029] Relay output terminals (such as 18, 19, 20, etc.): used to output inverter operating status signals (such as fault, running, etc.).

[0034] Input the motor nameplate parameters: P0304 (rated voltage), P0305 (rated current), P0307 (rated power), P0310 (rated frequency), P0311 (rated speed).

[0035] P0700 = 1 or 2 (Command source selection: 1 for BOP, 2 for terminal).

[0036] P1000 = 1, 2, or 3 (Frequency setting selection: 1 for BOP potentiometer, 2 for analog input 1, 3 for fixed frequency).

[0037] P1080 (minimum frequency), P1082 (maximum frequency).

[0038] P1120 / P1121 (acceleration / deceleration time).

[0039] P1300 = 0 (linear V / F control).

[0040] P3900 = 1 or 3 (End quick commissioning and reset parameters or calculate motor data only).

[0041] (2) Multi-speed control parameters: Configure the digital input terminal functions (such as P0701, P0702, P0703, etc.) to multi-speed commands.

[0042] Set fixed frequencies (such as P1001, P1002, P1003, etc.) to correspond to different speed segments.

[0043] (3) Analog control parameters: Set the analog input type (e.g., P0756 = 2 to select 4-20mA current input).

[0044] Adjust the correspondence between analog input and frequency (e.g., set P0757-P0760 to 4-20mA corresponding to 0-50Hz).

[0045] 3. Control Logic (1) Start-stop control: Start and stop are achieved via digital input terminals (such as 5 and 9). Pressing the start button starts the motor according to the set acceleration time; releasing the button stops the motor.

[0046] (2) Multi-speed control: Different speeds can be selected by combining different digital input terminals. For example, pressing buttons SB3, SB4, and SB5 will cause the motor to run at different frequencies.

[0047] (3) Analog speed control: By outputting a 4-20mA signal to the analog input terminal via an external potentiometer or DCS system, the output frequency of the frequency converter can be adjusted, thereby controlling the motor speed.
