Description

Technical Field

[0001] This application relates to the field of water treatment technology, specifically to an automatic weighing hopper. Background Technology

[0002] In water treatment, the precise dosing of various treatment agents is a crucial step in ensuring treatment effectiveness. Currently, the industry commonly uses tanks to store and dispense treatment agents. Traditional tanks typically have graduation lines on the tank wall, and operators determine the discharge volume by observing the liquid level on the graduation lines. This method of observing the liquid level can meet the basic requirements for discharging volume control when treating conventional opaque raw materials.

[0003] However, when transparent raw materials are stored in the tank, the liquid level is difficult to distinguish from the outside of the tank because the transparent raw materials are similar in color to the tank wall. Consequently, it is impossible to accurately judge the discharge volume. During the preparation of the reagents, this difficulty in observation leads to inaccurate dosage, making it difficult for the water treatment products to achieve the expected results and the ideal treatment goals, which seriously affects the quality and efficiency of water treatment work. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automatic weighing hopper that can accurately measure the weight of the hopper body and the material inside in real time. This replaces the traditional method of observing the discharge volume based on the liquid level, effectively solving the problem that it is difficult to observe the liquid level of transparent raw materials, leading to inaccurate judgment of the discharge volume.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic weighing hopper, comprising a base plate, a weighing scale fixedly mounted on the upper surface of the base plate, a protective plate fixedly connected to the upper side of the weighing scale, a support frame assembly on the upper side of the protective plate, a hopper body on the inner side of the support frame assembly, a level fixedly connected to the upper surface of the base plate, four sets of rectangular array adjustable foot assemblies on the upper side of the base plate, a discharge pipe fixedly mounted at the bottom of the hopper body, a first valve fixedly mounted on the outer side of the discharge pipe, a distribution pipe fixedly connected to the outer side of the discharge pipe, reaction tank bodies on both sides of the base plate, and the two ends of the distribution pipe fixedly connected to the interior of the reaction tank bodies on both sides, with a second valve installed at both ends of the distribution pipe.

[0006] The above solution uses a base plate as a fundamental load-bearing component to provide stable support for the entire structure. The adjustable foot assembly, combined with a level, allows for horizontal adjustment of the base plate, ensuring accurate weighing. The weighing scale can then accurately measure the weight of the main body of the hopper and the material inside in real time, replacing the traditional method of relying on liquid level to observe the discharge volume. This effectively solves the problem of difficulty in observing the liquid level and inaccurate discharge volume judgment for transparent raw materials. Furthermore, the support frame assembly, located on the upper side of the protective plate, provides stable support for the hopper body, ensuring a stable and reliable weighing process.

[0007] Furthermore, the support frame assembly includes a support ring fixedly connected to the upper side of the protective plate, and the support ring and the protective plate are fixedly connected by bolts.

[0008] With the above solution, the support ring is detachably connected to the protective plate by bolts, which not only ensures the overall structural stability of the support frame assembly, but also facilitates thorough cleaning of the inside of the material barrel and avoids cross-contamination between different batches of raw materials.

[0009] Furthermore, three sets of triangular support frames in a circular array are fixedly connected to the upper side of the support ring. Horizontal struts are fixedly connected to the inner sides of each of the three sets of triangular support frames. A first fixing ring is fixedly connected to the upper side of each of the three sets of horizontal struts. The inner side of the first fixing ring is in contact with the outer side of the material barrel body.

[0010] Through the above scheme, the triangular support frame and the cross brace form a triangular support system. The first fixing ring generates a radial constraint force on the main body of the material bucket, which effectively suppresses the shaking of the material bucket during the feeding process. At the same time, the support points of the three sets of circumferential arrays keep the main body of the material bucket in the center position, preventing the weighing data of the weighing scale from being distorted due to off-center loading, and ensuring the stability and reliability of the transparent raw material metering process.

[0011] Furthermore, a second fixing ring is provided between the support ring and the first fixing ring. Three sets of L-shaped support rods in a circumferential array are fixedly connected to the outer side of the second fixing ring. The two ends of the L-shaped support rods are respectively fixedly connected to the outer side of the first fixing ring and the outer side of the support ring.

[0012] With the above solution, the second fixing ring forms a secondary reinforcement layer between the support ring and the first fixing ring through the L-shaped support rod, which greatly improves the torsional resistance of the structure and ensures the accuracy of weighing data acquisition.

[0013] Furthermore, the adjustable foot assembly includes a fixed sleeve fixedly connected to the upper side of the base plate, a lead screw rotatably connected to the inner side of the fixed sleeve, a rotating handle fixedly connected to one end of the lead screw, and anti-slip textures provided on the outer side of the rotating handle.

[0014] The above solution uses a fixed sleeve and a lead screw to form a spiral lifting mechanism. The handle provides a labor-saving operating interface. At the same time, rotating the handle drives the lead screw to precisely adjust the local height of the base plate. With the help of a level, the equipment can be quickly leveled, eliminating weighing system errors caused by uneven ground and ensuring the absolute level of the transparent raw material metering reference surface.

[0015] Furthermore, the outer side of the lead screw is threaded with an internal threaded sleeve, and the bottom surface of the internal threaded sleeve is fixedly connected to a load-bearing base plate.

[0016] The above solution uses an internal threaded sleeve and a lead screw to form a self-locking support foot. The downward pressure generated by the threaded engagement keeps the load-bearing base plate firmly in contact with the ground, effectively preventing the adjustment mechanism from spontaneously shifting in a long-term vibration environment and maintaining the long-term stability of the weighing system.

[0017] Furthermore, the bottom surface of the load-bearing base plate is provided with anti-slip texture, and the load-bearing base plate is made of steel.

[0018] The above-mentioned solution, which combines the anti-slip texture on the bottom of the load-bearing base plate with steel material, increases the coefficient of friction with the ground and improves the structural resistance to deformation, while maintaining the long-term accuracy of the adjustment mechanism.

[0019] Furthermore, the fixed sleeve has two symmetrical guide grooves, and the outer side of the internal threaded sleeve is fixedly connected to two symmetrical sliders, with the outer side of the sliders slidably connected to the inner side of the guide grooves.

[0020] The above-mentioned solution, which sets up a guide groove and a slider to form a guide sliding structure to restrict the movement of the internal threaded sleeve, makes the height fine-tuning operation smoother and more precise, and further improves the leveling efficiency of the equipment.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This automatic weighing hopper uses a base plate as a fundamental load-bearing component to provide stable support for the entire structure. Adjustable feet, combined with a level, allow for horizontal adjustment of the base plate, ensuring accurate weighing. The weighing scale then accurately measures the weight of the hopper body and the material inside in real time, replacing the traditional method of relying on liquid level to observe the discharge volume. This effectively solves the problem of difficulty in observing the liquid level and inaccurate discharge volume judgment for transparent raw materials. Furthermore, the support frame assembly, located on the upper side of the protective plate, provides stable support for the hopper body, ensuring a stable and reliable weighing process.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 and Figure 2This embodiment of an automatic weighing hopper includes a base plate 1, which serves as a fundamental load-bearing component, providing stable support for the entire hopper structure. A weighing scale 2 is fixedly installed on the upper surface of the base plate 1. By setting the weighing scale 2, the weight of the hopper body 5 and the material inside can be accurately measured in real time, replacing the traditional method of observing the discharge volume based on the liquid level. This effectively solves the problem that it is difficult to observe the liquid level of transparent raw materials, leading to inaccurate judgment of the discharge volume. A protective plate 3 is fixedly connected to the upper side of the weighing scale 2. A support frame assembly 4 is provided on the upper side of the protective plate 3. The hopper body 5 is located inside the support frame assembly 4. A level 6 is fixedly connected to the upper surface of the base plate 1. Four sets of rectangular array adjustable foot assemblies 7 are provided on the upper side of the base plate 1. A discharge pipe 8 is fixedly installed at the bottom of the hopper body 5. A first valve 9 is fixedly installed on the outer side of the discharge pipe 8. A distribution pipe 10 is fixedly connected to the outer side of the discharge pipe 8. Both sides of the base plate 1 are equipped with reaction tank bodies 11. The two ends of the distribution pipe 10 are fixedly connected to the inside of the reaction tank bodies 11 on both sides. The above-mentioned connection of the distribution pipe 10 to the reaction tank bodies 11 on both sides can accurately control the material output and realize the precise dosing of the reagent. The two ends of the distribution pipe 10 are equipped with second valves 12. By setting the base plate 1 as a basic load-bearing component, it provides stable support for the entire structure. At the same time, with the action of the adjustable foot assembly 7 and the level 6, the base plate 1 can be adjusted horizontally to ensure the accuracy of weighing. Then, the weighing scale 2 can accurately measure the weight of the material barrel body 5 and the material inside in real time, replacing the traditional method of observing the discharge volume by liquid level. This effectively solves the problem that it is difficult to observe the liquid level of transparent raw materials, resulting in inaccurate judgment of the discharge volume. At the same time, the support frame assembly 4 is set on the upper side of the protective plate 3, which can stably support the material barrel body 5 and ensure the stability and reliability of the weighing process.

[0032] Please see Figure 1 and Figure 3The support frame assembly 4 includes a support ring 401 fixedly connected to the upper side of the protective plate 3. The support ring 401 and the protective plate 3 are fixedly connected by bolts. The support ring 401 and the protective plate 3 are detachably connected by bolts, which ensures the overall structural stability of the support frame assembly 4 and facilitates thorough cleaning of the inside of the material barrel body 5, avoiding cross-contamination between different batches of raw materials. Three sets of circumferentially arrayed triangular support frames 402 are fixedly connected to the upper side of the support ring 401. Horizontal support rods 403 are fixedly connected to the inner side of each of the three sets of triangular support frames 402. A first fixing ring 404 is fixedly connected to the upper side of each of the three sets of horizontal support rods 403. The inner side of the first fixing ring 404 contacts the outer side of the material barrel body 5. The triangular support frames 402 and the horizontal support rods 403 form a triangular support system. The first fixing ring 404 exerts a radial constraint force on the material barrel body 5, effectively suppressing the shaking of the material barrel during the feeding process. At the same time, the three sets of circumferentially arrayed support points keep the material barrel body 5 in a centered position. To prevent distortion of weighing data from the weighing scale 2 due to off-center loading and ensure stable and reliable measurement of transparent raw materials, a second fixing ring 405 is provided between the support ring 401 and the first fixing ring 404. Three sets of L-shaped support rods 406 in a circular array are fixedly connected to the outer side of the second fixing ring 405. The corners of the L-shaped support rods 406 are fixedly connected to the second fixing ring 405. Then, the two ends of the L-shaped support rods 406 are fixedly connected to the outer side of the first fixing ring 404 and the support ring 401. Thus, the L-shaped support rods 406, together with the triangular support frame 402, can form a triangular support structure, further increasing the stability of the material barrel body 5. The two ends of the L-shaped support rods 406 are respectively fixedly connected to the outer side of the first fixing ring 404 and the outer side of the support ring 401. The second fixing ring 405, through the L-shaped support rods 406, forms a secondary reinforcement layer between the support ring 401 and the first fixing ring 404, which greatly improves the torsional resistance of the structure and ensures the accuracy of weighing data acquisition.

[0033] Please see Figure 1 , Figure 4 and Figure 5The adjustable foot assembly 7 includes a fixed sleeve 701 fixedly connected to the upper side of the base plate 1. A lead screw 702 is rotatably connected to the inner side of the fixed sleeve 701. A handle 705 is fixedly connected to one end of the lead screw 702. The outer side of the handle 705 is provided with anti-slip texture. By setting the fixed sleeve 701 and the lead screw 702 to form a spiral lifting mechanism, the handle 705 provides a labor-saving operating interface. At the same time, rotating the handle 705 drives the lead screw 702 to accurately adjust the local height of the base plate 1. With the help of the level 6, the equipment can be quickly leveled, eliminating the weighing system error caused by uneven ground and ensuring the absolute level of the transparent raw material metering reference surface. An internal threaded sleeve 703 is threadedly connected to the outer side of the lead screw 702. A load-bearing base plate 704 is fixedly connected to the bottom surface of the internal threaded sleeve 703. By setting the internal threaded sleeve 703 and the lead screw 702 to form a self-locking support foot, the downward pressure generated by the threaded engagement makes the base plate 704 rotatably connected to the base plate 1. The load-bearing base plate 704 remains in close contact with the ground, effectively preventing spontaneous displacement of the adjustment mechanism in long-term vibration environments and maintaining the long-term stability of the weighing system. The bottom surface of the load-bearing base plate 704 is provided with anti-slip textures. The load-bearing base plate 704 is made of steel. This combination of anti-slip textures and steel material increases the coefficient of friction with the ground and improves the structure's resistance to deformation, maintaining the long-term accuracy of the adjustment mechanism. The fixed sleeve 701 has two symmetrical guide grooves 706. Two symmetrical sliders 707 are fixedly connected to the outer side of the internal threaded sleeve 703, and the outer side of the sliders 707 is slidably connected to the inner side of the guide grooves 706. The guide grooves 706 and sliders 707 form a guiding sliding structure that restricts the movement of the internal threaded sleeve 703, making height fine-tuning operations smoother and more precise, further improving the equipment's leveling efficiency.

[0034] In this embodiment, an automatic weighing hopper is provided with a base plate 1 as a basic load-bearing component, which provides stable support for the entire structure. At the same time, with the help of the adjustable foot assembly 7 and the level 6, the base plate 1 can be adjusted horizontally to ensure the accuracy of weighing. Then, the weighing scale 2 can accurately measure the weight of the hopper body 5 and the material inside in real time, replacing the traditional method of observing the discharge volume by liquid level. This effectively solves the problem that it is difficult to observe the liquid level of transparent raw materials, which leads to inaccurate judgment of the discharge volume. Meanwhile, the support frame assembly 4 is set on the upper side of the protective plate 3, which can stably support the hopper body 5 and ensure that the weighing process is stable and reliable.

[0035] The working principle of the above embodiment is as follows: After the raw materials are loaded into the main body 5 of the material bucket, the weighing scale 2 monitors the changes in material quality in real time. The raw materials are distributed to the main bodies 11 of the reaction tanks on both sides through the conveying channel formed by the discharge pipe 8 and the distribution pipe 10. At the same time, the first valve 9 and the second valve 12 can control the opening and closing of the discharge pipe 8 and the distribution pipe 10. Then, the level 6 continuously detects the level of the base plate 1. If tilting occurs, the operator rotates the handle 705 in the adjustable foot assembly 7 to drive the lead screw 702 to rise and fall. The internal threaded sleeve 703 and the load-bearing base plate 704 are connected to the load-bearing base plate 704. The synergistic effect achieves precise leveling. The support frame component 4 forms a stable support frame through the rigid connection between the support ring 401 and the protective plate 3. Then, the triangular truss system composed of the triangular support frame 402, the cross brace 403 and the first fixing ring 404 ensures the stability of the material barrel body 5. Then, the reinforcement layer composed of the second fixing ring 405 and the L-shaped support rod 406 further improves the stability of the material barrel body 5. The whole process relies entirely on the mass sensing data of the weighing scale 2 to replace the traditional liquid level observation, eliminate visual judgment errors, and realize the accurate measurement and distribution of transparent raw materials.
