Description

Technical Field

[0001] This utility model relates to the technical field of powder storage and conveying equipment, and in particular to a pulse-assisted flow powder container. Background Technology

[0002] Powder containers generally refer to silos, storage tanks, etc., which are widely used in chemical, food, and pharmaceutical industries to store powder materials such as flour, plastic granules, and cement.

[0003] Existing powder containers suffer from numerous problems in practical applications, severely restricting production efficiency and safety. Powders inside the container are prone to bridging on the inner wall or clogging the discharge port due to gravity compaction, electrostatic adsorption, or humidity, resulting in poor material flow. This requires manual tapping or unblocking, affecting production continuity and posing operational safety hazards. Although some containers are equipped with vibrating motors to aid flow, the vibration intensity is fixed and cannot adapt to powders of different particle sizes and moisture levels. Furthermore, long-term vibration can easily cause structural fatigue in the container. Traditional pneumatic flow aids often use continuous jet mode, which is not only energy-intensive and noisy, but may also cause powder splashing or stratification due to excessive airflow, further affecting the quality of material processing. Therefore, a pulse-assisted flow powder container is proposed to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a pulse-assisted flow powder container, which aims to solve many problems existing in the practical application of existing powder containers, which seriously restrict production efficiency and safety. Powder in the container is easily compacted by gravity, electrostatic adsorption, or affected by humidity, forming bridges on the inner wall or blocking the discharge port, resulting in poor material discharge. Manual knocking or unblocking is required, which not only affects the continuity of production, but also poses operational safety hazards. Although some containers are equipped with vibration motors to assist flow, the vibration intensity is fixed and cannot be adapted to powders of different particle sizes and humidity. Moreover, long-term vibration can easily cause fatigue of the container structure. Traditional pneumatic flow-assisting devices mostly adopt a continuous jet mode, which is not only energy-intensive and noisy, but may also cause powder to splash or separate due to excessive airflow, further affecting the quality of material processing.

[0005] To achieve the above objectives, the present invention proposes a pulse-assisted flow powder container, which includes a container body, a conical discharge hopper connected to the bottom of the container body, a discharge valve provided at the bottom of the conical discharge hopper, a pulse-assisted flow mechanism provided on the outside of the container body, and a pressure monitoring component provided on the top of the container body.

An air storage tank is connected to the input end of the electromagnetic pulse valve. An air compressor is installed on the outside of the air storage tank. The output end of the air compressor is connected to the air storage tank. A controller is bolted to the left side of the container body. The controller is electrically connected to the air compressor and the electromagnetic pulse valve respectively. A vibration structure is installed on the outside of the conical discharge hopper.

[0007] Preferably, the pressure monitoring component includes a pressure sensor disposed on the top of the container body, the monitoring end of the pressure sensor penetrating through the top of the container body and extending into the interior of the container body, and a breathing valve connected to the top of the container body.

[0008] Preferably, the vibration structure includes a vibration ring fixedly connected to the outside of the conical discharge hopper, a linkage plate fixedly connected to the outside of the vibration ring, and an eccentric vibration motor provided around the top of the linkage plate, the eccentric vibration motor being electrically connected to the controller.

[0012] Preferably, a support plate is welded to the left side of the conical discharge hopper, and a rubber support sleeve is adhered to the top of the support plate, with the rubber support sleeve located on the outside of the gas storage tank.

[0013] Preferably, the pulse nozzles are equidistantly distributed along the circumference of the container body, and the spraying end of the pulse nozzle is inclined at 30-45 degrees toward the central axis of the container body.

[0014] In the technical solution of this utility model, by setting up a container body, a conical discharge hopper, a pulse flow aid mechanism and a pressure monitoring component, the pulse flow aid mechanism controls the pulse nozzle of the annular air box to spray airflow through an electromagnetic pulse valve, which can accurately impact the powder bridging on the inner wall of the container.

[0027] This utility model provides a pulse-assisted flow powder container, which aims to solve many problems existing in the practical application of powder containers, which seriously restrict production efficiency and safety. Powder in the container is prone to bridging or blocking the discharge port on the inner wall due to gravity compaction, electrostatic adsorption or humidity, resulting in poor material discharge. Manual knocking or clearing is required, which not only affects the continuity of production, but also poses operational safety hazards. Although some containers are equipped with vibration motors to assist flow, the vibration intensity is fixed and cannot be adapted to powders of different particle sizes and moisture content. Moreover, long-term vibration can easily cause fatigue of the container structure. Traditional pneumatic flow-assisting devices mostly adopt a continuous jet mode, which is not only energy-intensive and noisy, but may also cause powder to splash or separate due to excessive airflow, further affecting the quality of material processing.

[0028] like Figure 1-5 As shown, the present invention provides a pulse-assisted flow powder container, including a container body 1, a conical discharge hopper 2 connected to the bottom of the container body 1, a discharge valve provided at the bottom of the conical discharge hopper 2, a pulse-assisted flow mechanism 3 provided on the outside of the container body 1, and a pressure monitoring component 4 provided on the top of the container body 1.

[0029] The pulse flow assist mechanism 3 includes an annular air box 31 fixedly connected to the outside of the container body 1. A pulse nozzle 32 is connected to the inside of the annular air box 31. The inside of the pulse nozzle 32 penetrates the outside of the container body 1 and extends into the inside. An electromagnetic pulse valve 33 is connected to the outside of the annular air box 31. An air storage tank 34 is connected to the input end of the electromagnetic pulse valve 33. An air compressor 35 is installed on the outside of the air storage tank 34. The output end of the air compressor 35 is connected to the air storage tank 34. A controller 36 is bolted to the left side of the container body 1. The controller 36 is electrically connected to the air compressor 35 and the electromagnetic pulse valve 33 respectively. A vibration structure 37 is installed on the outside of the conical discharge hopper 2.

[0030] In this invention, a container body 1, a conical discharge hopper 2, a pulse flow assist mechanism 3, and a pressure monitoring component 4 are configured. During use, powder enters and is stored through a material valve at the top of the container body 1. When discharging, the discharge valve is opened, and the powder falls naturally along the conical discharge hopper 2. When bridging or blockage occurs, the controller 36 starts the air compressor 35, storing compressed air in the air tank 34. Simultaneously, the electromagnetic pulse valve 33 is triggered, causing the gas in the air tank 34 to enter the annular air chamber 31. The gas is then sprayed into the container body 1 through the pulse nozzles 32 inside the annular air chamber 31, precisely impacting the powder bridging area. This process breaks down agglomerates and adherents. If the powder has high viscosity, the vibration structure 37 on the outside of the conical discharge hopper 2 is activated simultaneously. The vibration is transmitted to the conical discharge hopper 2 to assist the powder in detaching from the inner wall. Throughout the process, the pressure monitoring component 4 monitors the pressure inside the container body 1 in real time to prevent abnormal pressure caused by pulsed airflow. The controller 36 can adjust the pulse frequency and airflow intensity according to the powder characteristics (such as particle size and humidity) to form a synergistic flow aid with the vibration structure 37. This not only solves the structural fatigue problem of traditional single vibration, but also avoids the high energy consumption and powder splashing of continuous air jet, ensuring smooth material feeding and improving production efficiency and safety.

[0031] Please refer to the following: Figure 3 The pressure monitoring component 4 includes a pressure sensor 41 disposed on the top of the container body 1. The monitoring end of the pressure sensor 41 penetrates through the top of the container body 1 and extends into the interior of the container body 1. A breather valve 42 is connected to the top of the container body 1. In this embodiment, by setting the pressure monitoring component 4, the monitoring end of the pressure sensor 41 can sense the changes in air pressure inside the container body 1 in real time and transmit the data to the controller 36. When the pressure inside the container body 1 becomes abnormal due to pulse jetting or feeding, the controller 36 can adjust the relevant components in conjunction, and the breather valve 42 will automatically open to balance the internal and external air pressure, so as to avoid the abnormal pressure causing deformation of the container body 1 or affecting the powder discharge, and ensure the safe operation of the equipment.

[0032] For further information, please continue to refer to [link / reference]. Figure 4The vibration structure 37 includes a vibration ring 371 fixedly connected to the outside of the conical discharge hopper 2. A linkage plate 372 is fixedly connected to the outside of the vibration ring 371. An eccentric vibration motor 373 is provided around the top of the linkage plate 372. The eccentric vibration motor 373 is electrically connected to the controller 36. In this embodiment, by setting the vibration structure 37, the controller 36 starts the eccentric vibration motor 373 according to the characteristics of the powder. The centrifugal force generated by the rotation of the motor is transmitted to the vibration ring 371 through the linkage plate 372, causing the vibration ring 371 to drive the conical discharge hopper 2 to generate high-frequency vibration. This effectively solves the blockage caused by the stickiness or compaction of the powder in the discharge hopper. It works in conjunction with the pulse airflow to improve the smoothness of material discharge.

[0033] Please continue to refer to this. Figure 2 The inner wall of the container body 1 is coated with a polytetrafluoroethylene (PTFE) anti-stick layer, the thickness of which is 1-3 mm. In this embodiment, by setting the PTFE anti-stick layer, its 1-3 mm thickness can reduce the adhesion between the powder and the inner wall of the container body 1, reduce the adhesion of the powder to the inner wall caused by static electricity or humidity, and, in conjunction with pulsed airflow and vibration, further prevent bridging formation. At the same time, it facilitates cleaning and extends the equipment maintenance cycle.

[0034] Please refer to Figure 2 The controller 36 has a touch screen 5 embedded on its surface, and the controller 36 has a preset database of pulse parameters for different powders. In this embodiment, by setting the touch screen 5, the operator can directly access the preset database of pulse parameters for different powders (such as airflow intensity and frequency) in the controller 36, or manually input parameters to achieve precise control of the pulse flow-aiding mechanism 3, adapt to various powder characteristics, and operate conveniently and efficiently.

[0035] Additionally, please refer to Figure 2 A buzzer 6 is installed on the top of the controller 36 and is electrically connected to the controller 36. In this embodiment, by setting the buzzer 6, when the pressure sensor 41 detects abnormal pressure, equipment failure, or poor flow assistance, the controller 36 triggers the buzzer 6 to emit an alarm sound, promptly reminding the operator to intervene and avoid production interruption or safety hazards caused by the problem persisting.

[0036] Additionally, please refer to Figure 5 A support plate 7 is welded to the left side of the conical discharge hopper 2, and a rubber sleeve 8 is bonded to the top of the support plate 7. The rubber sleeve 8 is located on the outside of the gas storage tank 34. In this embodiment, by setting the support plate 7 and the rubber sleeve 8, the support plate 7 and the rubber sleeve 8 provide stable support for the gas storage tank 34. At the same time, the rubber sleeve 8 uses elasticity to buffer the vibration generated by the gas storage tank 34 during operation, reducing the impact of vibration transmission on the normal use of the gas storage tank 34.

[0037] Additionally, please refer to Figure 2The pulse nozzles 32 are evenly distributed around the circumference of the container body 1, and the spraying ends of the pulse nozzles 32 are inclined at 30-45 degrees toward the central axis of the container body 1. In this embodiment, by setting pulse nozzles 32 evenly distributed around the circumference of the container body 1 and inclined at 30-45 degrees toward the central axis, a uniform annular pulse airflow can be formed. The oblique spray can accurately impact the inner wall of the container body 1 and the powder accumulation area, enhance the airflow's debriding effect on bridging, and guide the powder to flow toward the conical discharge hopper 2, thereby improving the flow assist efficiency.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
