Description

Technical Field

[0001] The present invention relates to the technical field of pneumatic conveying, and specifically, it is a pneumatic conveying device with an auxiliary blowing function. Background Art

[0002] Pneumatic conveying technology is an engineering technology that uses gas as a carrier to convey powdery, granular or fibrous materials in a closed pipeline. It is widely used in industries such as chemical engineering, electric power, metallurgy, food processing, pharmaceuticals, and environmental protection, and has the advantages of long conveying distance, good airtightness, and high degree of automation. However, traditional pneumatic conveying systems still have the following technical bottlenecks in practical applications. Traditional equipment relies on a single air source to provide conveying power. Especially when conveying high-density, highly viscous or easily caking materials, uneven air flow distribution in the pipeline may lead to a sudden increase in local resistance, reducing the conveying efficiency. Materials are prone to form blockages due to a decrease in speed or collisions and accumulations at pipe elbows and diameter changes, and frequent shutdowns are required for cleaning. In addition, the intense friction between the material and the pipe wall not only aggravates pipe wear but also affects product quality. Summary of the Invention

[0003] The purpose of the present invention is to provide a pneumatic conveying device with an auxiliary blowing function to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A pneumatic conveying device with an auxiliary blowing function, including a Roots blower, a cooling cylinder, a thermoelectric component, a silo, a silo feed pipe, and a feeding component. An air inlet filter pipe is provided at the air inlet end of the Roots blower, and the air inlet end of the Roots blower is connected to the cooling cylinder. The thermoelectric component is installed on the Roots blower and the cooling cylinder. The thermoelectric component includes several thermoelectric conductors and several semiconductor refrigeration chips. The thermoelectric conductors and the semiconductor refrigeration chips are connected to a control system through a circuit. The feeding component includes a feed pipe and a feed cylinder. The feed pipe is communicated with the feed cylinder. The silo feed pipe is a three-way pipe and is connected between the cooling cylinder and the feed pipe, and the silo feed pipe is also communicated with the silo. The Roots blower inputs high-pressure gas to provide high-speed air flow for the entire conveying device. The material to be conveyed in the silo enters the conveying device through the silo feed pipe, enters a round pipe after passing through the feeding component, and is finally conveyed to other storage tanks.

[0005] Furthermore, each of the thermoelectric conductors is formed by connecting two conductor materials with different materials in a closed loop. One end where the two conductor materials are connected is arranged on the air inlet side of the Roots blower, and the other end where the two conductor materials are connected is arranged on the air outlet side of the Roots blower. One of the conductor materials in each thermoelectric conductor is connected to a power storage module. Since the Roots blower compresses air during operation, the temperature on the air outlet side of the Roots blower is higher than that on the air inlet side. According to the first thermoelectric effect, i.e., the Seebeck effect, when there is a temperature difference between the two contact points in a loop composed of two materials, a thermoelectric current will be generated in the loop, and the corresponding electromotive force is called the thermoelectric potential. The electric energy is stored through the power storage module, and the function of power generation and power storage is realized through the temperature difference of the Roots blower.

[0006] Furthermore, several wedge-shaped grooves are spirally formed on the cooling cylinder. A semiconductor refrigerating sheet is installed on one side of each wedge-shaped groove facing the Roots blower. The refrigerating end of the semiconductor refrigerating sheet faces the inside of the cooling cylinder. Each semiconductor refrigerating sheet is connected to the power storage module through a circuit. The air output from the Roots blower has heat. The power storage module supplies power to the semiconductor refrigerating sheet, causing the semiconductor refrigerating sheet to start refrigerating and cooling the air flow output from the Roots blower to prevent the heated air flow from affecting the quality of the transported material. Since the wedge-shaped grooves are arranged spirally, the air flow flowing through the cooling cylinder also advances spirally to achieve more uniform cooling of the air flow.

[0007] Furthermore, the feeding pipe is horizontally arranged, and the feeding cylinder is vertically arranged. The feeding cylinder is in the shape of a frustum of a cone, with the diameter of the top of the feeding cylinder smaller than that of the bottom. A supporting fence is arranged at the bottom of the feeding cylinder, and a round pipe is arranged at the top of the feeding cylinder. The round pipe is internally connected to the feeding cylinder, and the diameter of the round pipe is the same as that of the feeding pipe.

[0008] Furthermore, a screw rod is rotatably installed inside the feeding cylinder. The screw rod is conical, and the contour of the screw rod fits the inner wall contour of the feeding cylinder. The rotating shaft of the screw rod penetrates the bottom of the feeding cylinder, and a driven bevel gear is installed at the bottom of the rotating shaft of the screw rod. The driven bevel gear is located in the supporting fence.

[0009] Furthermore, a servo motor is arranged at the bottom of the feeding cylinder. The servo motor is connected to the control system through a circuit. A driving bevel gear is installed on the motor shaft of the servo motor. The driving bevel gear meshes with the driven bevel gear for transmission. During the process of material transmission, the servo motor is powered on to drive the driving bevel gear to rotate. The driving bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the screw rod to rotate. During the rotation of the screw rod, the flow direction of the material at the corner is guided. Since the contour of the screw rod fits the inner wall contour of the feeding cylinder, it plays a role in preventing the transported material from accumulating at the corner, solving the technical problem of material accumulation caused by the weakening of energy at the pipeline corner in pneumatic transmission.

[0010] Further, a first pressure detection pipe is provided on the material feeding pipe, and a filter screen is provided at the position where the material feeding pipe communicates with the first pressure detection pipe. A second pressure detection pipe is provided on the circular pipe, and a filter screen is also provided at the position where the circular pipe communicates with the second pressure detection pipe. A sealing plug is slidably and sealingly arranged in each of the first pressure detection pipe and the second pressure detection pipe. Springs are provided on the sides of the first pressure detection pipe and the second pressure detection pipe close to the filter screens. Since the air flow in the material feeding pipe and the material feeding cylinder is in a high-speed flowing state, the interiors of the material feeding pipe and the material feeding cylinder are both in a low-pressure state. Therefore, the sealing plugs in the first pressure detection pipe and the second pressure detection pipe both move towards the low-pressure side against the elastic force of the springs.

[0011] Further, a sensor is provided on the outer side of the material feeding cylinder. A first piston cylinder and a second piston cylinder are provided inside the sensor. The first piston cylinder is connected to the first pressure detection pipe through a pipeline, and the second piston cylinder is connected to the second pressure detection pipe through a pipeline. The diameters of the first piston cylinder and the second piston cylinder are smaller than the diameters of the first pressure detection pipe and the second pressure detection pipe. Since the first piston cylinder and the first pressure detection pipe are in a communicating state, when the sealing plug in the first pressure detection pipe moves, the pressure in the first piston cylinder decreases, causing the piston rod in the first piston cylinder to move, and then driving the rack to move. Similarly, the movement of the piston rod in the second piston cylinder also drives the rack on it to move.

[0012] Further, a rack is installed on each of the piston rods of the first piston cylinder and the second piston cylinder. A telescopic rod is provided inside the sensor. A gear is rotatably installed on the telescopic rod. A rotational variable resistor is provided at the connection between the gear and the telescopic rod. The rotational variable resistor is electrically connected to the control system. The gear is arranged between a pair of racks and meshes with the pair of racks. When the low air pressures inside the material feeding pipe and the material feeding cylinder are the same, the two racks move the same distance, and the gear between them will not rotate, but only move along with the racks at the same time, and the resistance value of the rotational variable resistor will not change. When the low air pressures inside the material feeding pipe and the material feeding cylinder are different, the two racks move different distances, the gear rotates, and the resistance value of the rotational variable resistor changes. The control system judges the air pressure changes in the material feeding pipe and the material feeding cylinder through the change in the resistance value of the rotational variable resistor. If the air pressure in the circular pipe decreases, the servo motor increases the rotation speed of the screw rod to increase the air flow velocity in the circular pipe and compensate for the air pressure loss compared with the material feeding pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By providing a thermoelectric conductor and utilizing the characteristic that the temperature of the air outlet side of the Roots blower is higher than that of the air inlet side, when there is a temperature difference between the two contact points in the loop composed of the two materials, a thermoelectric current will be generated in the loop, and the corresponding electromotive force is called the thermoelectric potential. The electric energy is stored through the energy storage module, and the function of power generation and energy storage is realized through the temperature difference of the Roots blower.

[0015] 2. The energy storage module is used to supply power to the semiconductor refrigeration sheet, causing the semiconductor refrigeration sheet to start refrigerating and cooling the air flow output by the Roots blower, so as to prevent the heated air flow from affecting the quality of the conveyed material. The air flow flowing through the cooling cylinder advances in a spiral manner to achieve more uniform cooling of the air flow.

[0016] 3. The sensor is used to detect the air pressure changes in the feeding pipe and the feeding cylinder. If the air pressure in the round pipe decreases, the servo motor increases the rotation speed of the screw rod, increases the air flow velocity in the round pipe, compensates for the air pressure loss between the round pipe and the feeding pipe, and at the same time, the screw rod prevents the conveyed material from accumulating at the corner, solving the technical problem of material accumulation caused by the weakening of energy at the pipe corner in pneumatic transmission.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment: As Figures 1-7 shown, the present invention provides a technical solution, a pneumatic conveying device with an auxiliary blowing function, including a Roots blower 1, a cooling cylinder 5, a thermoelectric component, a silo, a silo feed pipe 6 and a feeding component. An air inlet filter pipe 2 is arranged at the air inlet end of the Roots blower 1. The air inlet end of the Roots blower 1 is connected to the cooling cylinder 5. The thermoelectric component is installed on the Roots blower 1 and the cooling cylinder 5. The thermoelectric component includes several thermoelectric conductors 3 and several semiconductor refrigeration chips 23. The thermoelectric conductors 3 and the semiconductor refrigeration chips 23 are connected to the control system through circuits. The feeding component includes a feeding pipe 7 and a feeding cylinder 8. The feeding pipe 7 is communicated with the feeding cylinder 8. The silo feed pipe 6 is a three-way pipe. The silo feed pipe 6 is connected between the cooling cylinder 5 and the feeding pipe 7. The silo feed pipe 6 is also communicated with the silo. The Roots blower 1 inputs high-pressure gas to provide high-speed airflow for the entire conveying device. The material to be conveyed in the silo enters the conveying device through the silo feed pipe 6, passes through the feeding component and then enters the round pipe until it is conveyed to other storage tanks.

[0027] Each thermoelectric conductor 3 is formed by connecting two conductor materials with different materials in a closed loop. One end where the two conductor materials are connected is arranged on the air inlet side of the Roots blower 1, and the other end where the two conductor materials are connected is arranged on the air outlet side of the Roots blower 1. One of the conductor materials in each thermoelectric conductor 3 is connected with a power storage module 4. Since the Roots blower 1 compresses air during operation, the temperature on the air outlet side of the Roots blower 1 is higher than that on the air inlet side. According to the first thermoelectric effect, that is, the Seebeck effect, when there is a temperature difference between the two contact points in the loop composed of two materials, a thermoelectric current will be generated in the loop, and the corresponding electromotive force is called the thermoelectric potential. The electric energy is stored through the power storage module 4, and the function of power generation and power storage is realized through the temperature difference of the Roots blower 1.

[0028] Several wedge-shaped grooves are spirally arranged on the cooling cylinder 5. A semiconductor refrigeration chip 23 is installed on one side of each wedge-shaped groove facing the Roots blower 1. The refrigerating end of the semiconductor refrigeration chip 23 faces the inside of the cooling cylinder 5. Each semiconductor refrigeration chip 23 is connected to the power storage module 4 through a circuit. The air output from the Roots blower 1 has heat. The power storage module 4 supplies power to the semiconductor refrigeration chip 23, so that the semiconductor refrigeration chip 23 starts to refrigerate, cooling the airflow output from the Roots blower 1 to prevent the heated airflow from affecting the quality of the conveyed material. Since the wedge-shaped grooves are spirally arranged, the airflow flowing through the cooling cylinder 5 also advances spirally to achieve more uniform cooling of the airflow.

[0029] The feeding pipe 7 is horizontally arranged, the feeding cylinder 8 is vertically arranged, the feeding cylinder 8 is in the shape of a frustum of a cone, the diameter of the top of the feeding cylinder 8 is smaller than that of the bottom, a supporting shroud is arranged at the bottom of the feeding cylinder 8, a circular pipe is arranged at the top of the feeding cylinder 8, the circular pipe is internally communicated with the feeding cylinder 8, the diameter of the circular pipe is the same as that of the feeding pipe 7, a screw rod 9 is rotatably installed inside the feeding cylinder 8, the screw rod 9 is conical, the contour of the screw rod 9 fits with the inner wall contour of the feeding cylinder 8, the rotating shaft of the screw rod 9 penetrates through the bottom of the feeding cylinder 8, a driven bevel gear 10 is installed at the bottom of the rotating shaft of the screw rod 9, the driven bevel gear 10 is located in the supporting shroud, a servo motor 12 is arranged at the bottom of the feeding cylinder 8, the servo motor 12 is electrically connected with the control system through a circuit, a driving bevel gear 11 is installed on the motor shaft of the servo motor 12, the driving bevel gear 11 is meshed with the driven bevel gear 10 for transmission. During the process of material transmission, the servo motor 12 is powered on to drive the driving bevel gear 11 to rotate, the driving bevel gear 11 drives the driven bevel gear 10 to rotate, the driven bevel gear 10 drives the screw rod 9 to rotate. During the rotation of the screw rod 9, the flow direction of the material at the corner is guided. Since the contour of the screw rod 9 fits with the inner wall contour of the feeding cylinder 8, it plays a role in preventing the conveyed material from accumulating at the corner, and solves the technical problem of material accumulation caused by the weakening of energy at the pipeline corner in pneumatic transmission.

[0030] A first pressure detection pipe 13 is arranged on the feeding pipe 7, a filter screen is arranged at the position where the feeding pipe 7 is communicated with the first pressure detection pipe 13, a second pressure detection pipe 14 is arranged on the circular pipe, and a filter screen is also arranged at the position where the circular pipe is communicated with the second pressure detection pipe 14. A sealing plug 15 is slidably and sealingly arranged in both the first pressure detection pipe 13 and the second pressure detection pipe 14. A spring 16 is arranged on the inner side of the first pressure detection pipe 13 and the second pressure detection pipe 14 close to the filter screen. A sensor 17 is arranged on the outer side of the feeding cylinder 8. A first piston cylinder 18 and a second piston cylinder 19 are arranged inside the sensor 17. The first piston cylinder 18 is communicated with the first pressure detection pipe 13 through a pipeline, and the second piston cylinder 19 is communicated with the second pressure detection pipe 14 through a pipeline. The cylinder diameters of the first piston cylinder 18 and the second piston cylinder 19 are smaller than the pipe diameters of the first pressure detection pipe 13 and the second pressure detection pipe 14. Since the air flow in the feeding pipe 7 and the feeding cylinder 8 is in a high-speed flow state, the inside of the feeding pipe 7 and the feeding cylinder 8 is in a low-pressure state. Therefore, the sealing plugs 15 in the first pressure detection pipe 13 and the second pressure detection pipe 14 both move towards the low-pressure side against the elastic force of the spring 16. Since the first piston cylinder 18 is in communication with the first pressure detection pipe 13, when the sealing plug 15 in the first pressure detection pipe 13 moves, the pressure in the first piston cylinder 18 decreases, causing the piston rod in the first piston cylinder 18 to move, and then driving the rack 20 to move. Similarly, the piston rod of the second piston cylinder 19 also drives the rack 20 on it to move.

[0031] A rack 20 is installed on the piston rods of both the first piston cylinder 18 and the second piston cylinder 19. An expansion rod 21 is arranged inside the sensor 17. A gear 22 is rotatably installed on the expansion rod 21. A rotary rheostat (not shown in the figure) is arranged at the connection between the gear 22 and the expansion rod 21. The rotary rheostat is electrically connected to the control system circuit. The gear 22 is arranged between a pair of racks 20 and meshes with the pair of racks 20. When the low air pressures inside the feeding pipe 7 and the feeding cylinder 8 are the same, the two racks 20 move the same distance, and the gear 22 between them will not rotate but only move simultaneously with the racks 20, and the resistance value of the rotary rheostat will not change. When the low air pressures inside the feeding pipe 7 and the feeding cylinder 8 are different, the two racks 20 move different distances, the gear 22 rotates, and the resistance value of the rotary rheostat changes. The control system judges the air pressure changes in the feeding pipe 7 and the feeding cylinder 8 through the change in the resistance value of the rotary rheostat. If the air pressure in the circular pipe decreases, the servo motor 12 increases the rotation speed of the screw rod 9 to increase the air flow velocity in the circular pipe and compensate for the air pressure loss between it and the feeding pipe 7.

[0032] Working principle of the present invention: The Roots blower 1 inputs high-pressure gas to provide high-speed air flow for the entire conveying device. The materials to be conveyed in the silo enter the conveying device through the silo feeding pipe 6, enter the circular pipe after passing through the feeding assembly, and are finally conveyed to other storage tanks. Since the Roots blower 1 compresses air during operation, the temperature on the air outlet side of the Roots blower 1 is higher than that on the air inlet side. According to the first thermoelectric effect, i.e., the Seebeck effect, when there is a temperature difference between two contact points in a loop composed of two materials, a thermoelectric current will be generated in the loop, and the corresponding electromotive force is called the thermoelectric potential. The electric energy is stored through the energy storage module 4, and the function of power generation and energy storage is realized through the temperature difference of the Roots blower 1.

[0033] The air output from the Roots blower 1 has heat. The energy storage module 4 supplies power to the semiconductor refrigeration sheet 23, causing the semiconductor refrigeration sheet 23 to start refrigerating and cooling the air flow output from the Roots blower 1 to prevent the heated air flow from affecting the quality of the conveyed materials. Since the wedge-shaped grooves are arranged in a spiral pattern, the air flow passing through the cooling cylinder 5 also advances spirally to achieve more uniform cooling of the air flow.

[0034] During the process of material transmission, the servo motor 12 is powered on to drive the driving bevel gear 11 to rotate. The driving bevel gear 11 drives the driven bevel gear 10 to rotate. The driven bevel gear 10 drives the screw rod 9 to rotate. During the rotation of the screw rod 9, it guides the flow direction of the material at the corner. Since the contour of the screw rod 9 fits the inner wall contour of the feeding cylinder 8, it plays a role in preventing the conveyed materials from accumulating at the corner, solving the technical problem of material accumulation caused by the weakening of energy at the pipeline corner in pneumatic transmission.

[0035] Since the airflows in the feeding pipe 7 and the feeding cylinder 8 are in a high-speed flow state, the interiors of the feeding pipe 7 and the feeding cylinder 8 are both in a low-pressure state. Therefore, the sealing plugs 15 in the first pressure detection pipe 13 and the second pressure detection pipe 14 both move towards the low-pressure side against the elastic force of the springs 16. Since the first piston cylinder 18 is in communication with the first pressure detection pipe 13, when the sealing plug 15 in the first pressure detection pipe 13 moves, the pressure in the first piston cylinder 18 decreases, causing the piston rod in the first piston cylinder 18 to move, and then driving the rack 20 to move. Similarly, the piston rod movement of the second piston cylinder 19 also drives the rack 20 on it to move.

[0036] When the low air pressures inside the feeding pipe 7 and the feeding cylinder 8 are the same, the two racks 20 move the same distance, and the gear 22 between them will not rotate but only move simultaneously with the racks 20, and the resistance value of the rotary variable resistor will not change. When the low air pressures inside the feeding pipe 7 and the feeding cylinder 8 are different, the two racks 20 move different distances, the gear 22 rotates, and the resistance value of the rotary variable resistor changes. The control system judges the air pressure changes in the feeding pipe 7 and the feeding cylinder 8 through the change in the resistance value of the rotary variable resistor. If the air pressure in the circular pipe decreases, the servo motor 12 increases the rotation speed of the screw rod 9 to increase the air flow velocity in the circular pipe and compensate for the air pressure loss with the feeding pipe 7.
