Description

Technical Field

[0001] The invention belongs to the technical field of material storage tanks, and in particular relates to a material storage tank with automatic feeding and weighing functions. Background Art

[0002] A storage tank is a container used to store and store various substances (such as liquids, gases or solid particles). It is usually used in many fields such as industry, chemical industry, food, pharmaceuticals, energy, etc. Its main function is to store raw materials, finished products or intermediate products to ensure the smooth progress of the production process, avoid the waste of raw materials, and help automate the production process. In the production and processing of liquid products such as hair care shampoo, skin care cleansing, creams and lotions, it is usually necessary to store materials in liquid storage tanks, so as to store processed intermediate materials in the production process, ensure that there are enough materials for processing in the subsequent links, and maintain the smooth progress of the production process.

[0003] However, existing liquid storage tanks usually have the following technical problems when storing materials:

[0004] During the storage process, the materials in the storage tank cannot be weighed, resulting in inaccurate inventory management, which in turn affects the production plan. At the same time, the liquid level of the materials in the tank cannot be monitored, resulting in excessive amounts of materials entering the storage tank during the storage process, causing the storage tank to be overloaded, which not only wastes products and increases processing costs, but also pollutes the working environment;

[0005] When storing liquid products, different products have different fluidities, but existing storage tanks cannot adjust the feeding speed according to the fluidity of the products. For products with poor fluidity, if the feeding speed is too fast, it is easy to cause local excessive accumulation in the storage tank, affecting the feeding efficiency and uniformity. For products with good fluidity, if the feeding speed is too slow, it will affect the storage efficiency of the product, resulting in a decrease in overall production efficiency.

[0006] Therefore, there is an urgent need for a storage tank with automatic feeding and weighing functions that can perform weighing and automatically shut off feeding when the material is excessive, and can adjust the feeding speed according to the fluidity of the product.

[0022] Compared with the existing technology, the advantages of the storage tank with automatic feeding and weighing functions are:

[0023] The present invention provides a weighing mechanism and a feeding mechanism. When storing materials, the material is transported into the tank body by a material pump. The material's own gravity presses the piezoelectric sensor to monitor the weight of the material in real time, thereby realizing an automatic weighing function. At the same time, during the feeding process, the increase in the material liquid level will drive the float plate to rise, so that the material liquid level can be detected by the distance between the distance sensor and the float plate. When the material liquid level approaches the top of the tank body, the material pump is automatically closed through the PLC control panel to prevent excessive material from entering the storage tank, avoid waste of material, and save processing costs.

[0024] The present invention provides an adjusting mechanism. During the feeding process, the fluidity of the material is detected by a moving plate. When the fluidity of the material is poor, the shear stress of the material during the conveying process is large, and the larger the distance that the moving plate is driven to move in the sliding groove, the smaller the gap between the two baffle plates is, and the feeding speed of the material is reduced, thereby avoiding local excessive accumulation in the storage tank due to excessive feeding speed, thereby improving the feeding efficiency and uniformity. When the fluidity of the material is good, the shear stress of the material during the conveying process is small, thereby increasing the gap between the two baffle plates and increasing the feeding speed of the material, so that the material can fill the storage tank more quickly, thereby improving the overall production efficiency.

[0025] The present invention sets a vibration mechanism. During the feeding process, the motor drives the worm to rotate, and then the worm wheel drives the transmission rod to rotate, so that the two transmission plates can reciprocate horizontally along the reciprocating thread sections on both sides of the transmission rod. In the process of the two transmission plates approaching each other, the swing plate can swing away from the conveying cylinder and hit the outer wall of the conveying cylinder under the elastic force of the second spring. Therefore, during the feeding process, vibration is introduced to promote the flow of materials and avoid material blockage during the feeding process.

[0026] The present invention provides an air flow distribution mechanism. While the motor drives the worm to rotate, the annular plate is also driven to rotate through the driving gear and the annular tooth groove, so that the annular air guide box at the lower end of the annular plate is rotated, and the air flow is evenly transported into the tank body through the exhaust nozzle at the lower end of the annular air guide box. The impact of the air flow on the material in the tank body enables the material to flow and distribute more evenly.

[0027] The present invention provides a suction component, and during the rotation of the annular plate, multiple guide wheels installed at the lower end of the annular plate are periodically resisted by the guide protrusions, thereby driving the reciprocating vertical displacement of the annular piston plate, and continuously passing through the suction channel to discharge the outside air through the exhaust nozzle, thereby realizing automatic suction of the outside gas and automatic discharge of the gas, without the need to provide an additional driving source such as a suction pump, the overall linkage of the device is high, and the degree of automation is improved while saving processing costs.

DETAILED DESCRIPTION

[0036] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0037] Example: Refer to Figures 1 to 7 , a storage tank with automatic feeding and weighing functions, comprising:

[0038] The tank body 1, specifically, has a discharge port and an exhaust port on the side wall inside the tank body 1. The discharge port is used to discharge the material inside the tank body 1 after storage is completed, and the exhaust port is used to prevent the subsequent suction component 66 from causing excessive air pressure inside the tank body 1 during operation to prevent potential safety hazards. In addition, both the discharge port and the exhaust port are provided with an opening and closing valve, which can be closed during storage to prevent the material from overflowing;

[0039] The weighing mechanism 2 is used to automatically weigh the material in the tank body 1. The weighing mechanism 2 includes a bearing plate 21 which is sealingly and slidably connected to the inner wall of the tank body 1. A plurality of piezoelectric sensors 22 distributed in a circumferential array are provided between the lower wall of the bearing plate 21 and the inner bottom wall of the tank body 1.

[0040] The feeding mechanism 3 is used to automatically stop feeding after the feeding is completed to avoid the overflow of the material. The feeding mechanism 3 includes a material pump 31 fixedly connected to the upper end of the tank body 1. The output end of the material pump 31 is connected to the inside of the tank body 1. A floating plate 32 is slidably connected to the inner wall of the tank body 1 in the vertical direction. A distance sensor 33 is fixedly connected to the position above the floating plate 32 in the tank body 1. A PLC control panel is provided on the outer wall of the tank body 1. The PLC control panel controls the closing of the material pump 31 according to the electrical signal transmitted by the distance sensor 33.

[0041] In view of the problem that the prior art cannot weigh the materials in the storage tank, resulting in inaccurate inventory management, which in turn affects the production plan, and at the same time, the liquid level of the material in the tank body cannot be monitored, resulting in excessive material entering the storage tank during the storage process, causing the storage tank to be overloaded, which not only wastes products and increases processing costs, but also pollutes the working environment. The present invention sets a weighing mechanism 2 and a feeding mechanism 3. When storing materials, the material is transported into the tank body 1 through a material pump 31, so that the material falls on the supporting plate 21. The piezoelectric sensor 22 is pressed by the material's own gravity to monitor the weight of the material in real time, realize the automatic weighing function, and avoid inaccurate inventory management. At the same time, during the feeding process, the increase in the material liquid level will drive the floating plate 32 to rise, so that the material liquid level is detected by the distance between the distance sensor 33 and the floating plate 32. When the material liquid level approaches the top of the tank body 1, the material pump 31 is automatically closed through the PLC control panel to prevent excessive material from entering the storage tank, avoid waste of materials, and save processing costs.

[0042] The regulating mechanism 4 is used to adjust the material discharge speed according to the fluidity of the material. The regulating mechanism 4 includes a conveying cylinder 41 fixedly connected to the upper end of the tank body 1, and a conveying channel 42 is fixedly connected on the side wall of the conveying cylinder 41. The output end of the material pump 31 is connected to the conveying channel 42. A sliding groove 43 is opened on the inner wall of the conveying channel 42. A moving plate 44 is slidably connected in the sliding groove 43. A first spring 45 is provided between the moving plate 44 and the inner wall of the sliding groove 43. Two side plates 46 are fixedly connected to the lower end of the conveying channel 42. Two symmetrically arranged rotating rods 47 are rotatably connected between the two side plates 46. A material blocking plate 48 is fixedly connected to each rotating rod 47, and the inclination angle of the material blocking plate 48 is controlled by the moving plate 44.

[0043] The adjusting mechanism 4 also includes two liquid storage chambers 49 opened in the side wall of the conveying cylinder 41, and a piston block 410 is sealed and slidably connected in the liquid storage chamber 49. Push plates 411 are fixedly connected to the upper and lower side walls of the movable plate 44. The two push plates 411 are respectively sealed and slidable on the inner walls of the two liquid storage chambers 49. The position above the piston block 410 in the liquid storage chamber 49 is filled with hydraulic oil. A first rack 412 is fixedly connected to the bottom of the piston block 410 through a connecting rod, and a first gear 413 meshing with the first rack 412 is fixedly connected to the middle position of the rotating rod 47.

[0044] Specifically, the bottom ends of both sides of the conveying cylinder 41 are fixedly connected with material guide plates to prevent the material from contacting the first gear 413 and to prevent the material from overflowing from both sides of the baffle plate 48 as much as possible, thereby improving the effect of regulating the material discharge speed.

[0045] In view of the problem that the prior art cannot adjust the feeding speed according to the fluidity of the product, for products with poor fluidity, if the feeding speed is too fast, it is easy to cause local excessive accumulation in the storage tank, affecting the feeding efficiency and uniformity. For products with good fluidity, if the feeding speed is too slow, it will affect the storage efficiency of the product, resulting in a decrease in the overall production efficiency. The present invention sets an adjustment mechanism 4. During the feeding process, the fluidity of the material is detected by the moving plate 44. When the fluidity of the material is poor, the shear stress of the material during the conveying process is large, and the larger the distance that the moving plate 44 is displaced in the sliding groove 43, the larger the distance that the push plate 411 moves toward the inner side of the liquid storage chamber 49, and the piston block 410 is able to move downward in the liquid storage chamber 49 and pass through the first gear 413 and the first gear 413 drive the rotating rod 47 to rotate, so that the baffle plate 48 on the rotating rod 47 swings toward the middle position of the conveying cylinder 41, thereby reducing the gap between the two baffle plates 48, reducing the feeding speed of the material, avoiding local excessive accumulation in the storage tank caused by excessive feeding speed, and improving the feeding efficiency and uniformity. When the fluidity of the material is good, the shear stress of the material during the conveying process is small, the smaller the displacement distance of the moving plate 44 in the sliding groove 43, the piston block 410 moves upward in the liquid storage chamber 49, causing the baffle plates 48 on the rotating rod 47 to swing toward the two sides of the conveying cylinder 41, thereby increasing the gap between the two baffle plates 48, and increasing the feeding speed of the material, so that the material can fill the storage tank more quickly, thereby improving the overall production efficiency.

[0046] A vibration mechanism 5 is provided at the upper end of the tank body 1 to avoid material blockage during feeding and to prevent the material from adhering to the inner wall of the conveying cylinder 41. The vibration mechanism 5 includes a motor 51 fixedly connected to the upper end of the tank body 1, a worm 52 is fixedly connected to the output end of the motor 51, two support plates 53 are fixedly connected to the upper end of the tank body 1, a transmission rod 54 is provided between the two support plates 53, a worm wheel 55 meshing with the worm 52 is provided in the middle position of the transmission rod 54, reciprocating thread sections 56 are provided on both sides of the transmission rod 54, and the transmission rod A transmission plate 57 is threadedly connected to the reciprocating thread section 56 on 54, and a second rack 58 is fixedly connected to the transmission plate 57. The upper end of the tank body 1 is rotatably connected to two symmetrically arranged swing rods 59, and a second gear 510 meshing with the second rack 58 at the corresponding position is installed on the swing rod 59 through a one-way bearing. A swing plate 511 is fixedly connected to the swing rod 59, and an impact roller 512 is fixedly connected to the side of the swing plate 511 close to the conveying cylinder 41, and a second spring 513 is provided between the swing plate 511 and the outer wall of the conveying cylinder 41.

[0047] Specifically, the transmission plate 57 is slidably connected to the upper wall of the tank body 1 in the horizontal direction, so that the transmission plate 57 will not rotate along the reciprocating thread segment 56 when moving along the reciprocating thread segment 56, thereby avoiding motion interference.

[0048] In order to further avoid the blockage of materials during the feeding process, the present invention is provided with a vibration mechanism 5. During the feeding process, the motor 51 drives the worm 52 to rotate, and then the worm wheel 55 drives the transmission rod 54 to rotate, so that the two transmission plates 57 can reciprocate horizontally along the reciprocating threaded sections 56 on both sides of the transmission rod 54. In the process of the two transmission plates 57 approaching each other, the second rack 58 will drive the swing rod 59 to rotate through the second gear 510, so that the swing plate 511 can swing away from the conveying cylinder 41, and when the second rack 58 is separated from the second gear 510, the swing rod 59 and the swing plate 511 can hit the outer wall of the conveying cylinder 41 under the elastic force of the second spring 513, so that during the feeding process, vibration is introduced to promote the flow of materials and avoid the blockage of materials during the feeding process. In the process of the two transmission plates 57 moving away from each other, the second gear 510 cannot rotate under the action of the one-way bearing, so that the swing plate 511 can only periodically move away from the conveying cylinder 41 to avoid motion interference.

[0049] An air flow distribution mechanism 6 is provided above the tank body 1, which is used to evenly transport the air flow into the tank body 1 during the feeding process. The air flow distribution mechanism 6 includes a driving gear 61 fixedly connected to the peripheral side wall below the worm 52. An annular plate 62 is rotatably connected to the upper wall of the tank body 1. An annular tooth groove 63 meshing with the driving gear 61 is provided on the inner wall of the annular plate 62. The part of the annular plate 62 extending into the tank body 1 is fixedly connected to an annular air guide box 64. The lower end of the annular air guide box 64 is fixedly connected to a plurality of exhaust nozzles 65 distributed in a circular array. A suction assembly 66 is provided in the annular air guide box 64 for automatically sucking outside air to save a driving source.

[0050] In order to improve the uniformity of materials during storage, the present invention sets an air flow distribution mechanism 6. While the motor 51 drives the worm 52 to rotate, it also drives the annular plate 62 to rotate through the driving gear 61 and the annular tooth groove 63, so that the annular air guide box 64 at the lower end of the annular plate 62 rotates, and the air flow is evenly transported into the tank body 1 through the exhaust nozzle 65 at the lower end of the annular air guide box 64. The impact of the air flow on the material in the tank body 1 allows the material to flow and distribute more evenly.

[0051] The suction assembly 66 includes an annular piston plate 661 which is sealingly and slidably connected to the inner wall of the annular air guide box 64, the upper end of the annular piston plate 661 is fixedly connected to a connecting plate 662, the part of the connecting plate 662 extending above the annular plate 62 is fixedly connected to a mounting ring plate 663, the lower wall of the mounting ring plate 663 is rotatably connected to a plurality of guide wheels 664 distributed in a circular array, the upper end of the tank body 1 is fixedly connected to a plurality of guide protrusions 665 distributed in a circular array, the guide wheel 664 periodically contacts and rolls with the plurality of guide protrusions 665, the peripheral side wall of the annular air guide box 64 is fixedly connected to an exhaust channel 666, and the exhaust channel 666 extends to the top of the tank body 1.

[0052] Specifically, one-way valves are provided in the air suction channel 666 and the multiple exhaust nozzles 65. Through the setting of the one-way valve, when the annular piston block 410 performs reciprocating vertical displacement in the annular air guide box 64, the outside air can only be pumped into the annular air guide box 64 through the air suction channel 666, and the air in the annular air guide box 64 can only be pumped out through the exhaust nozzles 65 to avoid air backflow. At the same time, considering that the air suction channel 666 is annular in arrangement and it is inconvenient to set a one-way valve therein, a sealing ring plate can be fixedly installed in the air suction channel 666, and a plurality of air inlet nozzles distributed in a circular array are provided on the sealing ring plate. There are multiple one-way valves in the air suction channel 666 and they are respectively arranged in each air inlet nozzle.

[0053] Specifically, the connecting plate 662 is slidably connected to the annular plate 62 in the vertical direction, a vertical limit slider is arranged on the side wall of the connecting plate 662, and a vertical limit groove which cooperates with the limit slider for sliding is arranged on the contact surface between the annular plate 62 and the connecting plate 662, so that the connecting plate 662 can only slide up and down along the annular plate 62, thereby limiting the connecting plate 662, so that when the guide wheel 664 contacts the guide protrusion 665, the connecting plate 662 can only move in the vertical direction relative to the annular plate 62, avoiding its rotation relative to the annular plate 62, resulting in the annular piston plate 661 being unable to perform reciprocating vertical displacement (the limit slider and the limit groove are both existing common technologies, and can be set at any position of the connecting plate 662 and the annular plate 62, so they are not marked in the figure).

[0054] Specifically, the positions above the tank body 1 on both sides of the exhaust channel 666 are fixedly connected by a first U-shaped block, and the positions above the tank body 1 on both sides of the annular plate 62 are fixedly connected by a second U-shaped block, to prevent the tank body 1 from being separated by the annular plate 62 and the exhaust channel 666, causing instability of the tank body 1 as a whole.

[0055] In addition, the present invention sets a suction assembly 66, and during the rotation of the annular plate 62, multiple guide wheels 664 at the lower end of the mounting ring plate 663 will be periodically resisted by the guide protrusion 665, so that the mounting ring plate 663 can drive the connecting plate 662 and the annular piston plate 661 to periodically move upward and fall under the action of gravity. Through the reciprocating vertical displacement of the annular piston plate 661, the outside air is continuously pumped into the annular air guide box 64 through the suction channel 666, and the air in the annular air guide box 64 is continuously discharged through the exhaust nozzle 65, thereby realizing automatic suction of external gas and automatic discharge of gas, without the need to set up an additional driving source such as a suction pump, and the overall linkage of the device is high, which improves the degree of automation and saves processing costs.

[0056] The present invention can be explained by the following operation mode:

[0057] When storing materials, the materials are transported into the tank body 1 through the material pump 31, so that the materials fall on the carrying plate 21. The weight of the materials is pressed on the piezoelectric sensor 22 by the material's own gravity, and the weight of the materials is monitored in real time to realize the automatic weighing function. At the same time, during the feeding process, the increase of the material liquid level will drive the floating plate 32 to rise, so that the liquid level of the materials is detected by the distance between the distance sensor 33 and the floating plate 32. When the material liquid level approaches the top of the tank body 1, the material pump 31 is automatically closed through the PLC control panel to prevent excessive material from entering the storage tank;

[0058] During the feeding process, the fluidity of the material is detected by the moving plate 44. When the fluidity of the material is poor, the shear stress of the material during the conveying process is large, and the larger the displacement distance of the moving plate 44 in the sliding groove 43, the piston block 410 moves downward in the liquid storage chamber 49, and the first gear 413 and the first gear 413 are used to swing the transfer baffle plate 48 to the middle position of the conveying cylinder 41, thereby reducing the gap between the two baffle plates 48 and reducing the feeding speed of the material. When the fluidity of the material is good, the shear stress of the material during the conveying process is small, and the smaller the displacement distance of the moving plate 44 in the sliding groove 43, the piston block 410 moves upward in the liquid storage chamber 49, and the two baffle plates 48 swing to the two sides of the conveying cylinder 41, thereby increasing the gap between the two baffle plates 48 and increasing the feeding speed of the material.

[0059] The worm 52 is driven to rotate by the motor 51, and the transmission rod 54 is driven to rotate by the worm wheel 55, so that the two transmission plates 57 can reciprocate horizontally along the reciprocating threaded sections 56 on both sides of the transmission rod 54, and the swing plate 511 can swing away from the conveying cylinder 41 through the second rack 58 and the second gear 510. When the second rack 58 is separated from the second gear 510, the swing rod 59 and the swing plate 511 can hit the outer wall of the conveying cylinder 41 under the elastic force of the second spring 513, so that vibration is introduced during the feeding process to promote the flow of materials;

[0060] When the worm 52 rotates, the annular plate 62 is driven to rotate through the driving gear 61 and the annular tooth groove 63, so that the annular air guide box 64 at the lower end of the annular plate 62 rotates. During the rotation of the annular plate 62, the multiple guide wheels 664 installed at the lower end of the annular plate 663 will be periodically abutted by the guide protrusion 665, so that the annular piston plate 661 performs reciprocating vertical displacement, continuously pumping outside air into the annular air guide box 64 through the exhaust channel 666, and continuously exhausting the air in the annular air guide box 64 through the exhaust nozzle 65. The impact of the airflow on the material in the tank body 1 allows the material to flow and distribute more evenly.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
