Description

Technical Field

[0001] This application relates to the field of weighing equipment technology, and in particular to a connection structure for discharging material from a weighing tank. Background Technology

[0002] A weighing tank is a device used to measure the weight of materials. Weighing tanks are widely used in chemical, food, pharmaceutical and other industrial fields.

[0003] A weighing tank typically consists of a tank body and a load cell. The tank body holds the material, while the load cell is installed at the bottom of the tank or on a support assembly. The load cell converts gravity signals into electrical signals, which are then converted into tank weight data by a control unit. A discharge pipe is located at the bottom of the tank, connecting to the next process equipment via a conveying pipeline to deliver a fixed quantity of material to that equipment.

[0004] In existing technology, the discharge pipe of the tank is a bent pipe structure, and some material will adhere to the inner wall of the bent section of the discharge pipe. Since it is difficult for workers to clean the material on the bent section of the discharge pipe, when the material accumulates to a certain amount in the bent section of the discharge pipe, the solidified material will block the discharge pipe, thus affecting the discharge of the weighing tank. Utility Model Content

[0005] To facilitate the cleaning of accumulated materials in the discharge pipe and reduce the risk of material clogging the discharge pipe, this application provides a connection structure for discharging materials from a weighing tank.

[0006] This application provides a connection structure for discharging material from a weighing tank, which adopts the following technical solution:

[0007] A connection structure for discharging material from a weighing tank is disclosed. The weighing tank has a discharge pipe at its bottom, the discharge pipe having a bent section. The discharge pipe is used to connect to a conveying pipeline to quantitatively convey material to a process equipment. The connection structure includes a flexible connecting pipe and fasteners. Two fasteners are provided, located at both ends of the flexible connecting pipe. One end of the flexible connecting pipe is detachably connected to the discharge pipe via the fasteners, and both ends of the flexible connecting pipe are detachably connected to the conveying pipeline via the fasteners.

[0008] By adopting the above technical solution, a flexible connecting pipe is added between the existing discharge pipe and the conveying pipe, so that workers can periodically separate the flexible connecting pipe from the discharge pipe. This allows workers to use tools to clean the material on the inner wall of the discharge pipe, reducing the risk of material clogging the discharge pipe.

[0009] Optionally, a support component may also be included, which is used to support the flexible connecting pipe.

[0010] By adopting the above technical solution, the flexible connection pipe is supported by the support components, thereby reducing the stress on the flexible connection pipe.

[0011] Optionally, the support assembly includes a base plate, a sleeve, a connecting column, and a support plate. The base plate is disposed on the ground, the sleeve is vertically disposed on the base plate, the sleeve has an insertion groove for the connecting column to be inserted, the connecting column is threaded to the side wall of the insertion groove, and the support plate is disposed on the connecting column and is used to support the flexible connecting pipe.

[0012] By adopting the above technical solution, the support height of the support plate can be adjusted through the threaded connection between the connecting column and the sleeve; this adapts to the on-site installation height of the flexible connection pipe, making it easier for workers to install the connection structure.

[0013] Optionally, it also includes an elastic sealing ring, which is fixed on the inner peripheral wall of the flexible connecting pipe. There are two elastic sealing rings, which are disposed at both ends of the flexible connecting pipe. The elastic sealing ring is used to press and abut against the discharge pipe or conveying pipe.

[0014] By adopting the above technical solution and setting an elastic sealing ring, the sealing performance of the connection between the flexible connection pipe and the discharge pipe or conveying pipe can be improved, reducing the risk of material leakage.

[0015] Optionally, the flexible connecting pipe includes a flow section and a connecting section. There are two connecting sections, which are disposed on both sides of the flow section. The connecting sections are integrally formed with the flow section. The inner diameter of the connecting section is larger than the inner diameter of the flow section. The connecting section is used for sleeve connection with the discharge pipe or conveying pipe. The elastic sealing ring is disposed on the inner peripheral wall of the connecting section and abuts against the flow section.

[0016] By adopting the above technical solution, the elastic sealing ring abuts against the flow section, so that the side wall of the flow section has a limiting effect on the elastic sealing ring, reducing the risk of the elastic sealing ring falling off.

[0017] Optionally, the fastener includes a fixing component and a moving component. The fixing component has a through-passage channel for the connecting section to pass through. The fixing component includes an integrally formed fixing connection part and a fixing abutment part. The inner peripheral wall of the fixing connection part is used to bond and fix it to the outer peripheral wall of the discharge pipe or conveying steel pipe. The outer peripheral wall of the fixing connection part is provided with external threads. The fixing abutment part has several clearance grooves spaced in annularly, so that the fixing abutment part has clearance space for inward or outward expansion. The outer periphery of the fixing abutment part is provided with a first guide surface. The moving component is sleeved on... The fixed component has an outer periphery, and the movable component includes a movable connecting part and a movable abutting part. The inner peripheral wall of the movable connecting part is provided with an internal thread. The movable connecting part is threadedly connected to the fixed connecting part. The movable abutting part is disposed opposite to the fixed abutting part. The inner peripheral wall of the movable abutting part is provided with a second guide surface. When the movable connecting part is threadedly connected to the fixed connecting part, the second guide surface abuts against the first guide surface, and the movable connecting part forces the fixed connecting part to retract inward. The retraction of the fixed connecting part clamps the connecting segment.

[0018] By adopting the above technical solution, workers can rotate the sliding component to make the fastener include a flexible connecting pipe, thus facilitating worker operation.

[0019] Optionally, the fixed abutment is located on the side of the fixed connection portion away from the flow section; when the fastener moves away from the flow section, the movable abutment forces the fixed abutment to retract inward, so that the fixed abutment retracts inward to clamp the connection section.

[0020] By adopting the above technical solution, the moving part moves away from the flow section. When the operator rotates the moving part, the connecting section of the flexible connection pipe tends to move towards the discharge pipe and the conveying steel pipe, thereby increasing the squeezing effect of the side wall of the flow section on the elastic sealing ring and improving the connection sealing performance of the flexible connection pipe.

[0021] Optionally, along the axial direction of the fixed abutment portion, the inner peripheral wall of the fixed abutment portion is provided with a plurality of limiting grooves spaced apart.

[0022] By adopting the above technical solution, a groove is provided on the inner peripheral wall of the fixed abutment part to improve the friction between the fixed abutment part and the flexible connecting pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By adding a flexible connecting pipe between the existing discharge pipe and the conveying pipe, workers can periodically separate the flexible connecting pipe from the discharge pipe, so that workers can use tools to clean the material on the inner wall of the discharge pipe, reducing the risk of material clogging the discharge pipe;

[0025] 2. The elastic sealing ring abuts against the flow section, so that the side wall of the flow section has a limiting effect on the elastic sealing ring, reducing the risk of the elastic sealing ring falling off;

[0026] 3. The moving part moves away from the flow section, so that when the operator rotates the moving part, the connecting section of the flexible connection pipe tends to move towards the discharge pipe and the conveying steel pipe, thereby increasing the squeezing effect of the side wall of the flow section on the elastic sealing ring and improving the connection sealing performance of the flexible connection pipe.

[0034] The following is in conjunction with the appendix Figure 1 Section 6 provides further details regarding this application.

[0035] This application discloses a connection structure for discharging material from a weighing tank. (Refer to...) Figure 1The weighing tank 1 has a discharge pipe 11 at its bottom, which has a bend 111. The discharge pipe 11 is used to connect to the conveying pipe 2 to quantitatively convey materials to a process device. Materials easily adhere to the bend 111 of the discharge pipe 11. After a certain amount of material accumulates in the bend 111, the condensed material will block the discharge pipe 11, thus affecting the discharge from the weighing tank. In this embodiment, both the discharge pipe 11 and the conveying pipe 2 are steel pipe structures.

[0036] Reference Figure 2 The connection structure for discharging material from the weighing tank is located between the discharge pipe 11 and the conveying pipe 2. The connection structure for discharging material from the weighing tank includes a flexible connecting pipe 3, a sealing ring 4, a support component 5, and fasteners 6.

[0037] Reference Figure 2 One end of the flexible connecting pipe 3 is detachably connected to the discharge pipe 11, and the other end of the flexible connecting pipe 3 is detachably connected to the conveying pipe 2. The connection method between the flexible connecting pipe 3 and the discharge pipe 11 is the same as the connection method between the flexible connecting pipe 3 and the conveying pipe 2; in this embodiment, the connection method between the flexible connecting pipe 3 and the discharge pipe 11 is used as an example for explanation.

[0038] Reference Figure 2 and Figure 3 The flexible connecting pipe 3 includes a flow section 31 and a connecting section 32. Two connecting sections 32 are provided, located on both sides of the flow section 31, and are integrally formed with the flow section 31. The inner diameter of the connecting section 32 is larger than the inner diameter of the flow section 31. One end of the connecting section 32 is fitted onto the outside of the discharge pipe 11, and the other end of the connecting pipe is fitted onto the outer periphery of the conveying pipe 2. The bottom wall of the flow section 31 abuts against the discharge pipe 11 or the conveying pipe 2.

[0039] Reference Figure 3 The elastic sealing ring 4 is fixed on the inner circumferential wall of the connecting section 32 in the flexible connecting pipe 3, and abuts against the flow section 31. The abutment between the elastic sealing ring 4 and the flow section 31 provides a limiting effect on the elastic sealing ring 4, reducing the risk of the elastic sealing ring 4 falling off. Two elastic sealing rings 4 are provided, located at both ends of the flexible connecting pipe 3; the two elastic sealing rings 4 respectively press against the discharge pipe 11 and the conveying pipe 2; this improves the sealing performance of the connection between the flexible connecting pipe 3 and the discharge pipe 11 or the conveying pipe 2, reducing the risk of material leakage.

[0040] Reference Figure 2 and Figure 3Two fasteners 6 are provided, and the two fasteners 6 are located at both ends of the flexible connecting pipe 3. One end of the flexible connecting pipe 3 is detachably connected to the discharge pipe 11 via the fasteners 6, and both ends of the flexible connecting pipe 3 are detachably connected to the conveying pipe 2 via the fasteners 6. In this embodiment, the structure of the fastener 6 is explained using the fastener 6 on the discharge pipe 11 as an example.

[0041] Reference Figure 3 The fastener 6 includes a fixing part 61 and a moving part 62. The fixing part 61 has a through-passing channel for the connecting section 32 to pass through. The moving part 62 is sleeved on the outer periphery of the fixing part 61 and is threadedly connected to the fixing part 61.

[0042] Reference Figure 4 and Figure 5 The fixing member 61 includes an integrally formed fixing connection part 611 and a fixing abutment part 612, with the fixing abutment part 612 disposed on the side of the fixing connection part 611 away from the flow section 31. The inner peripheral wall of the fixing connection part 611 is bonded and fixed to the outer peripheral wall of the discharge pipe 11, and the outer peripheral wall of the fixing connection part 611 is provided with external threads.

[0043] Reference Figure 5 and Figure 6 The fixed abutment portion 612 has several clearance grooves 6121 spaced out in an annular pattern, so that the fixed abutment portion 612 has clearance space that can be recessed or expanded outward. The fixed abutment portion 612 has a first guide surface 6122 on its outer periphery. In this embodiment, the distance from the first guide surface 6122 to the discharge pipe 11 increases along the direction away from the flow section 31 of the flexible connecting pipe 3.

[0044] Reference Figure 4 and Figure 6 The movable component 62 is sleeved on the outer periphery of the fixed component 61. The movable component 62 includes a movable connecting portion 621 and a movable abutting portion 622. The inner peripheral wall of the movable connecting portion 621 is provided with an internal thread, and the movable connecting portion 621 is threadedly connected to the fixed connecting portion 611. The movable abutting portion 622 is disposed opposite to the fixed abutting portion 612, and the inner peripheral wall of the movable abutting portion 622 is provided with a second guide surface 6221. In this embodiment, along the direction away from the flow section 31 of the flexible connecting pipe 3, the distance from the second guide surface 6221 to the discharge pipe 11 increases progressively.

[0045] Reference Figure 4 and Figure 6When the movable connecting part 621 is threadedly connected to the fixed connecting part 611, the fixed part 61 moves away from the flow section 31, and the second guide surface 6221 abuts against the first guide surface 6122. When the fixed part 61 continues to rotate towards the discharge pipe 11, the movable connecting part 621 forces the fixed connecting part 611 to retract inward, and the fixed connecting part 611 retracts inward to clamp the connecting section 32. The operator can rotate the sliding part to make the fastener 6 include the flexible connecting pipe 3, thereby facilitating the operator's operation.

[0046] Reference Figure 5 and Figure 6 Simultaneously, through the coordinated action of the first guide surface 6122 and the second guide surface 6221, when the moving part 62 moves towards the discharge pipe 11, the moving part 62 causes the fixed part 61 and the flexible connecting pipe 3 to both tend to move towards the discharge pipe 11. This allows the flow section 31 in the flexible connecting pipe 3 to further compress the elastic sealing ring 4, thereby improving the sealing performance between the flexible connecting pipe 3 and the discharge pipe 11. Therefore, when the weighing tank conveys materials to the next process equipment, the risk of material leakage can be reduced.

[0047] Reference Figure 6 Meanwhile, along the axial direction of the fixed abutment portion 612, a plurality of limiting grooves 6123 are spaced apart on the inner peripheral wall of the fixed abutment portion 612. By providing grooves on the inner peripheral wall of the fixed abutment portion 612, the frictional force between the fixed abutment portion 612 and the flexible connecting pipe 3 is increased.

[0048] Reference Figure 2 The support assembly 5 includes a base plate 51, a sleeve 52, a connecting column 53, and a support plate 54. The base plate 51 is placed on the ground, and the sleeve 52 is vertically mounted on the base plate 51. The sleeve 52 has an insertion groove 521 for the connecting column 53 to be inserted into. The connecting column 53 is threadedly connected to the side wall of the insertion groove 521. The support plate 54 is mounted on the connecting column 53 and is used to support the flexible connecting pipe 3. By using the support assembly 5 to support the flexible connecting pipe 3, the tensile force on the connection parts at both ends of the flexible connecting pipe 3 can be reduced when materials flow through it, thus reducing the risk of grout leakage. The threaded connection between the connecting column 53 and the sleeve 52 allows adjustment of the support height of the support plate 54, enabling the support assembly 5 to adapt to the on-site installation height of the flexible connecting pipe 3, facilitating the installation of the connection structure by the workers.

[0049] The implementation principle of a connection structure for discharging material from a weighing tank according to an embodiment of this application is as follows:

[0050] Reference Figure 1 and Figure 2By adding a flexible connecting pipe 3 between the existing discharge pipe 11 and the conveying pipe 2, the staff can periodically separate the flexible connecting pipe 3 from the discharge pipe 11, so that the staff can use tools to clean the material on the inner wall of the discharge pipe 11, reducing the risk of material clogging the discharge pipe 11.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
