Description

Technical Field

[0001] This invention relates to the field of steelmaking technology, and in particular to a steelmaking feeding device and steelmaking equipment. Background Technology

[0002] Steelmaking is the core process in modern steel production. The process involves feeding various raw materials (such as scrap steel, ferroalloys, slagging agents, etc.) into a steelmaking furnace (such as a converter, electric arc furnace, etc.) according to process requirements for smelting and reaction.

[0003] As the first step in the steelmaking process, the efficiency, accuracy, and orderliness of the charging operation directly affect the stability of subsequent smelting processes, energy consumption, material yield, and the final quality of molten steel. In existing technologies, charging operations in steelmaking workshops typically rely on overhead cranes (bridge cranes) in conjunction with hoisting tools such as material baskets or electromagnetic chucks to lift materials from the stockpile to the furnace front and directly pour them into the steelmaking furnace. While this traditional charging method is direct, it has the following significant technical defects and limitations in actual production:

[0004] Material mixing impact and splashing issues: The materials required for steelmaking often vary in size and density. Traditional methods involve mixing materials of different sizes and pouring them into the furnace all at once. Larger, heavier materials falling into the molten steel generate violent impacts and splashes. This not only poses safety hazards and can easily damage the furnace lining, but also causes localized fluctuations in the temperature and composition of the molten steel, disrupting the stability of the molten pool and affecting the uniformity of the metallurgical reaction.

[0005] Heat loss and low energy efficiency: When charging a steelmaking furnace, the furnace cover or door needs to be opened, resulting in the escape of high-temperature flue gas and a large amount of radiant heat loss. The traditional charging process is time-consuming, especially when the material is loosely piled up and the pouring is not smooth, which prolongs the furnace opening time, causing huge waste of heat energy and increasing the energy consumption of steelmaking.

[0006] Lack of material pretreatment and classification: Existing feeding systems typically lack pretreatment functions for materials before the furnace. Direct feeding of unsorted and unprocessed materials into the furnace may result in fine powder being carried away by the flue gas prematurely (increasing dust levels), while larger materials may require longer melting and reaction times, affecting production rhythm and process control precision.

[0007] Insufficient automation and intelligence: The feeding process relies heavily on the experience and coordination of crane operators and ground control personnel, and the control of material hoisting paths, placement point positioning, and feeding sequence lacks precise automated coordination. This may lead to unstable feeding efficiency and make it difficult to achieve seamless integration and linkage with advanced steelmaking process control systems.

[0008] Inefficient space utilization and process integration: The working areas and timing of hoisting equipment (overhead cranes) and ground transportation equipment (such as rail flatbed trucks) often overlap and there is waiting time, resulting in insufficient logistics integration and limiting the improvement of the overall material flow efficiency in the workshop. Summary of the Invention

[0009] To address these issues, the industry has made some attempts at improvement, such as using dedicated feeding vehicles or conveyor belts. However, these often focus on a single transportation function and fail to fundamentally solve the problems of refined material processing (such as screening and compaction) before entering the furnace, as well as the sequential, precise, and rapid delivery. Therefore, there is an urgent need to develop an integrated steelmaking feeding device and corresponding steelmaking equipment that can achieve automatic material reception, intelligent classification, compact processing, orderly transportation, and precise step-by-step delivery, thereby improving the overall efficiency, stability, and economy of the steelmaking process.

[0010] The technical solutions provided by the embodiments of the present invention are as follows:

[0011] The present invention provides a steelmaking feeding device and steelmaking equipment, comprising: a hoisting structure and a conveying structure distributed below the hoisting structure;

[0012] The conveying structure includes a fixed plate, a slide rail, a drive trolley, and a storage cavity;

[0013] The fixed plate is distributed below the hoisting structure, the slide rail is fixed at equal intervals on the fixed plate, the storage cavity is distributed on one side of the drive trolley, and the drive trolley drives the storage cavity to slide on the slide rail, which is used to realize the material transportation of the storage cavity to the hoisting structure.

[0014] The inner wall of the storage cavity is fixed with a sieve plate, which divides the inner cavity of the storage cavity into upper and lower cavities. A squeezing structure is provided in the upper cavity, which is used to squeeze the material inside the storage cavity. The lower cavity is used to collect the material sieved by the sieve plate, thereby realizing the classified transportation of the material lifted by the hoisting structure in the storage cavity.

[0015] The upper cavity and the lower cavity of the receiving cavity are both equipped with electrically controlled doors, and the control terminals of the electrically controlled doors are controlled by an external computer system.

[0016] Three eddy current sensors are fixed on the top surface of the fixed plate on each of the slide rails. Each eddy current sensor can detect the position of the moving trolley and transmit the detection information to the external computer control system.

[0017] The receiving cavity is a tubular structure with openings at the top and bottom. A guide plate is fixed to the lower opening of the receiving cavity. The guide plate is an inclined plate structure. The end of the guide plate near the drive trolley is higher than the end of the guide plate away from the drive trolley, thereby allowing the material screened by the sieve plate to be conducted to the vicinity of the electrically controlled door.

[0018] The guide plate is rotatably connected to a support base plate at one end away from the drive trolley via a rotating hinge. The support base plate includes a sliding seat, a limiting baffle, and a support electric push rod.

[0019] The sliding seat is fixed to one side of the driving trolley, the limiting baffle is fixed to the bottom surface of the sliding seat, and the limiting baffle abuts against both sides of the slide rail. The supporting electric push rod is rotatably connected between the guide plate and the sliding seat.

[0020] The electrically controlled door of the upper cavity of the storage chamber includes an upper baffle, an upper sealing door, a first electric push rod, and an upper telescopic rod.

[0021] The upper baffle is fixed to the discharge end of the storage cavity, the upper sealing door is rotatably connected to the bottom surface of the upper baffle, the first electric push rod and the upper telescopic rod are rotatably connected between the upper sealing door and the upper baffle, and the upper telescopic rod is distributed on one side of the first electric push rod.

[0022] The electrically controlled door of the lower cavity of the storage chamber includes a lower baffle, a lower sealing door, a second electric push rod, and a lower telescopic rod;

[0023] The lower baffle plate is fixed to one end of the screen plate away from the drive trolley. The lower sealing door is rotatably connected to the lower end of the lower baffle plate. The second electric push rod and the lower telescopic rod are rotatably connected between the lower baffle plate and the lower sealing door. The lower telescopic rod is distributed on one side of the second electric push rod.

[0024] The extrusion structure includes a hydraulic cylinder, a baffle, and an extrusion plate;

[0025] The extrusion plate slides in the inner cavity of the upper part of the storage cavity. The lower end of the extrusion plate abuts against the sieve plate. A baffle is fixed to the inner wall of the storage cavity on the side of the extrusion plate away from the upper baffle. The baffle is elastic. A push hydraulic cylinder is fixed to the inner wall of the storage cavity on the side of the extrusion plate away from the upper baffle.

[0026] The hoisting structure includes a horizontal drive frame, a vertical drive frame, a storage structure, clamping components, and a pull rope;

[0027] The horizontal drive frame is distributed on one side of the fixed plate, the vertical drive frame slides horizontally on the horizontal drive frame, the storage structure slides vertically on the vertical drive frame, the clamping member is distributed below the storage structure, and the pull rope is fixed between the storage structure and the clamping member.

[0028] A steelmaking apparatus includes: a steelmaking furnace and a flue gas recovery structure;

[0029] The steelmaking furnace is used to collect the material discharged from the receiving chamber. The flue gas recovery structure is fixed on one side of the receiving end of the steelmaking furnace. When the material discharged from the receiving chamber is put into the receiving end of the steelmaking furnace, the flue gas recovery structure collects the flue gas at the receiving end of the steelmaking furnace.

[0030] The receiving end of the steelmaking furnace is fixed with an installation ring, and an inclined plate is fixed between the installation ring and the fixing plate. The inclined plate is used to guide the material discharged from the receiving cavity to the receiving end of the steelmaking furnace, so that the steelmaking furnace can melt the material discharged from the receiving cavity.

[0031] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0032] 1. This invention utilizes a sieve plate within the receiving chamber to automatically separate materials into upper and lower layers based on particle size during material transport. Combined with an independently controlled electrically operated door, it ensures that materials are fed into the steelmaking furnace strictly following a "fine to coarse" order. This design avoids the problems of mixed materials of different sizes and violent splashing of molten steel, as well as large fluctuations in molten pool temperature and composition, caused by the one-time dumping of materials into the furnace in traditional methods. It significantly improves the stability and safety of the feeding process, creating favorable conditions for subsequent efficient and stable metallurgical reactions.

[0033] 2. This invention features a compression structure driven by a hydraulic cylinder at the upper part of the receiving cavity, which compresses loose materials into dense blocks within the cavity. This significantly increases the material capacity for a single transport and makes the material pouring into the furnace faster and smoother. Combined with fully automated track conveying and positioning, the entire feeding process is compact, significantly shortening the opening time of the steelmaking furnace charging port, thereby minimizing the escape of high-temperature flue gas and radiant heat loss within the furnace, achieving significant energy savings and improved production efficiency.

[0034] 3. The entire device is centrally controlled by an external computer control system, utilizing eddy current sensors for precise positioning of the drive trolley (e.g., points A, B, and C), coordinating various stages such as hoisting, receiving, pressing, transporting, and dumping. From material receiving and sorting to fixed-point feeding, a continuous and precise automated production line is formed. This not only reduces reliance on manual operation and improves the reliability and repeatability of feeding operations, but also lays a solid hardware foundation for the intelligent linkage control of material flow and the main smelting process in the steelmaking workshop.

[0045] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0046] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0047] In practical use, when traditional steelmaking feeding devices feed steelmaking equipment, the feeding device usually brings loose materials into the steelmaking equipment. When the loose materials are put into the steelmaking equipment, larger particles will be put into the steelmaking equipment along with smaller particles. At this time, the molten steel splashed by the larger particles will disturb the airflow inside the steelmaking equipment. The disturbed airflow will cause the smaller particles to be suspended inside the steelmaking equipment, making it difficult for the smaller particles to be put into the molten steel inside the steelmaking equipment, thus affecting the steelmaking equipment's ability to melt materials. In order to solve this problem, the following structure is proposed.

[0048] like Figures 1 to 8 As shown, an embodiment of the present invention provides a steelmaking feeding device and steelmaking equipment, including: a hoisting structure and a conveying structure distributed below the hoisting structure;

[0049] The conveying structure includes a fixed plate 2, a slide rail 23, a drive trolley 41, and a receiving cavity 4;

[0050] The fixed plate 2 is distributed below the hoisting structure, and the slide rail 23 is fixed on the fixed plate 2 at equal intervals. The storage cavity 4 is distributed on one side of the drive trolley 41. The drive trolley 41 drives the storage cavity 4 to slide on the slide rail 23 to realize the material transportation of the storage cavity 4 to the hoisting structure.

[0051] The inner wall of the storage cavity 4 is fixed with a sieve plate 415. The sieve plate 415 divides the inner cavity of the storage cavity 4 into upper and lower cavities. The upper cavity is equipped with a squeezing structure, which is used to squeeze the material inside the storage cavity 4. The lower cavity is used to collect the material screened by the sieve plate 415, thereby realizing the classified transportation of the material lifted by the hoisting structure in the storage cavity 4.

[0052] The upper cavity and the lower cavity of the storage cavity 4 are both equipped with electrically controlled doors at their discharge ends. The control end of the electrically controlled doors is controlled by an external computer system.

[0053] Specifically, in actual use, the staff first fixes the fixing plate 2 on the ground, and then the hoisting structure hoists the materials required for steelmaking into the inside of the storage cavity 4. When the materials required for steelmaking are hoisted into the inside of the storage cavity 4, the sieve plate 415 can screen the materials required for steelmaking. The smaller materials screened by the sieve plate 415 can be distributed in the lower cavity of the storage cavity 4, and the larger materials screened by the sieve plate 415 can be distributed in the upper cavity of the storage cavity 4. This can realize the classification and storage of materials hoisted by the hoisting structure in the storage cavity 4.

[0054] After the storage cavity 4 classifies and stores the materials hoisted by the hoisting structure, the drive trolley 41 drives the storage cavity 4 to slide on the slide rail 23 to realize the transportation of materials hoisted by the hoisting structure. When the storage cavity 4 moves to the vicinity of the steelmaking equipment, the materials inside the storage cavity 4 can be poured into the interior of the steelmaking equipment.

[0055] It is important to note that when the receiving chamber 4 is emptying materials into the steelmaking equipment, both the upper and lower discharge ends of the receiving chamber 4 are equipped with electrically controlled doors. Operators can pre-open the lower electrically controlled door of the receiving chamber 4, allowing smaller materials screened by the sieve plate 415 to be fed into the steelmaking equipment. After the smaller materials are fed into the steelmaking equipment, operators can open the upper electrically controlled door of the receiving chamber 4, allowing larger materials screened by the sieve plate 415 to be fed into the steelmaking equipment. This prevents both larger and smaller materials from being fed into the steelmaking equipment simultaneously, ensuring that the materials required for steelmaking do not mix with the molten steel inside the equipment.

[0056] In one possible implementation, three eddy current sensors 24 are fixed on the top surface of the fixed plate 2 on each slide rail 23. Each eddy current sensor 24 can detect the position of the drive trolley 41 and transmit the detection information to the external computer control system.

[0057] Specifically, in order to facilitate the differentiation of the position of the eddy current sensor 24, the eddy current sensor 24 on the slide rail 23 near the clamping member 13 is set as B, the eddy current sensor 24 on the slide rail 23 away from the steelmaking furnace 3 is set as A, and the eddy current sensor 24 on the slide rail 23 near the steelmaking furnace 3 is set as C.

[0058] In the initial state, the drive trolley 41 is parked above the eddy current sensor 24 at part A. When the hoisting structure needs to transport materials into the storage cavity 4, the drive trolley 41 drives the storage cavity 4 to slide forward on the slide rail 23. When the drive trolley 41 moves to above the eddy current sensor 24 at part B, the eddy current sensor 24 at part B can transmit a signal to the external computer control system. During this process, the external computer control system controls the drive trolley 41 to stop moving, which facilitates the hoisting structure to transport materials into the storage cavity 4.

[0059] After the hoisting structure delivers materials into the receiving cavity 4, the external computer control system controls the drive trolley 41 to move forward. During this process, the extrusion structure extrudes the materials inside the receiving cavity 4. When the materials are extruded by the extrusion structure, the sieve plate 415 can screen the materials inside the receiving cavity 4, thereby realizing the screening and receiving of the materials transported by the hoisting structure in the receiving cavity 4.

[0060] In one possible implementation, the receiving cavity 4 is a tubular structure with openings at the top and bottom. A guide plate 49 is fixed to the lower opening of the receiving cavity 4. The guide plate 49 is an inclined plate structure. The end of the guide plate 49 near the drive trolley 41 is higher than the end of the guide plate 49 away from the drive trolley 41, so that the material screened by the sieve plate 415 is conducted to the vicinity of the electric control door.

[0061] Specifically, after the sieve plate 415 sieves the material inside the receiving cavity 4, the lower cavity of the receiving cavity 4 can receive the material sieved by the sieve plate 415. At this time, smaller materials will be distributed in the lower cavity of the receiving cavity 4, and larger materials will be distributed in the upper cavity of the receiving cavity 4, thereby realizing the classification and storage of materials hoisted by the hoisting structure in the receiving cavity 4.

[0062] In one possible implementation, the end of the guide plate 49 away from the drive trolley 41 is rotatably connected to a support base plate via a rotating hinge 416. The support base plate includes a sliding seat 48, a limiting baffle 411, and a support electric push rod 410.

[0063] The sliding seat 48 is fixed on one side of the drive trolley 41, and the limiting baffle 411 is fixed relative to the bottom surface of the sliding seat 48. At the same time, the limiting baffle 411 abuts against both sides of the slide rail 23, and the electric push rod 410 is rotatably connected between the guide plate 49 and the sliding seat 48.

[0064] Specifically, the drive trolley 41 can move the receiving cavity 4 through the sliding seat 48, thereby enabling the drive trolley 41 to transport the material inside the receiving cavity 4, facilitating the dumping of the material into the steelmaking equipment. When the drive trolley 41 moves above the eddy current sensor 24 at point C, the eddy current sensor 24 can transmit a signal to the external computer control system. At this time, the external computer control system can control the supporting electric push rod 410 to work, thereby causing the receiving cavity 4 to rotate on the sliding seat 48, facilitating the dumping of the material inside the receiving cavity 4 into the steelmaking equipment.

[0065] In one possible implementation, the electrically controlled door of the upper cavity of the storage cavity 4 includes an upper baffle 42, an upper sealing door 43, a first electric push rod 44, and an upper telescopic rod 417.

[0066] The upper baffle 42 is fixed to the discharge end of the storage cavity 4, the upper sealing door 43 is rotatably connected to the bottom surface of the upper baffle 42, the first electric push rod 44 and the upper telescopic rod 417 are rotatably connected between the upper sealing door 43 and the upper baffle 42, and the upper telescopic rod 417 is distributed on one side of the first electric push rod 44.

[0067] In one possible implementation, the electrically controlled door of the lower cavity of the storage cavity 4 includes a lower baffle 45, a lower sealing door 47, a second electric push rod 46, and a lower telescopic rod 418.

[0068] The lower baffle 45 fixes the screen plate 415 away from the end of the drive trolley 41. The lower sealing door 47 is rotatably connected to the lower end of the lower baffle 45. The second electric push rod 46 and the lower telescopic rod 418 are rotatably connected between the lower baffle 45 and the lower sealing door 47. The lower telescopic rod 418 is distributed on one side of the second electric push rod 46.

[0069] Specifically, when the material inside the receiving cavity 4 needs to be poured into the steelmaking equipment, the external computer control system pre-controls the second electric push rod 46 to work. At this time, the second electric push rod 46, together with the lower telescopic rod 418, drives the lower sealing door 47 to open, which can realize the pouring of a small amount of material into the steelmaking equipment.

[0070] When smaller materials are poured into the steelmaking equipment, the external computer control system controls the first electric push rod 44 to work. At this time, the first electric push rod 44, together with the telescopic rod 417, drives the upper sealing door 43 to open, so that larger materials inside the receiving cavity 4 can be poured into the steelmaking equipment.

[0071] It should be noted that when workers pour smaller materials into the steelmaking equipment, the smaller weight of the materials avoids causing a large impact on the molten steel, which facilitates the airflow balance inside the steelmaking equipment and makes it easier for workers to put larger materials into the steelmaking equipment later.

[0072] In one possible implementation, the extrusion structure includes a hydraulic cylinder 412, a baffle 413, and an extrusion plate 414.

[0073] The extrusion plate 414 slides in the inner cavity of the upper part of the storage cavity 4. The lower end of the extrusion plate 414 abuts against the sieve plate 415. A baffle plate 413 is fixed to the inner wall of the storage cavity 4 on the side of the extrusion plate 414 away from the upper baffle plate 42. The baffle plate 413 is elastic. A push hydraulic cylinder 412 is fixed to the inner wall of the storage cavity 4 on the side of the extrusion plate 414 away from the upper baffle plate 42.

[0074] Specifically, after the hoisting structure puts materials into the receiving cavity 4, the external computer control system drives the hydraulic cylinder 412 to work. At this time, the hydraulic cylinder 412 can drive the extrusion plate 414 to extrude the materials inside the receiving cavity 4, so that the materials can occupy a more compact space in the receiving cavity 4. This avoids the need for more time when the materials inside the receiving cavity 4 are poured into the steelmaking equipment. It also avoids the need for the receiving port of the steelmaking equipment to be open for a long time when receiving materials, thus preventing a lot of heat from being discharged from the receiving port of the steelmaking equipment.

[0075] When the extrusion plate 414 extrudes the material inside the receiving cavity 4, the size of the compressed material inside the receiving cavity 4 depends on the extrusion force applied to the material by the hydraulic cylinder 412. The operator can control the hydraulic cylinder 412 to work according to the external computer control system.

[0076] When the extrusion plate 414 extrudes the material inside the receiving cavity 4, the upper baffle 42 can block the material inside the receiving cavity 4, thereby facilitating the material to form inside the receiving cavity 4. When the extruded material needs to be put into the steelmaking equipment, the lower baffle 45 can guide the material, thereby facilitating the material to be put into the steelmaking equipment.

[0077] It should be noted that when the screen plate 415 screens the material, the extrusion plate 414 moves in contact with the screen plate 415. This allows the extrusion plate 414 to clean the material stuck on the screen plate 415. At the same time, when the material inside the receiving cavity 4 is poured out, the material on the screen plate 415 can also be separated from the screen plate 415 under the action of gravity, thereby achieving the self-cleaning effect of the screen plate 415 of the device.

[0078] In one possible implementation, the hoisting structure includes a horizontal drive frame 1, a vertical drive frame 11, a storage structure 12, a clamping member 13, and a pull rope 131.

[0079] The horizontal drive frame 1 is distributed on one side of the fixed plate 2, the vertical drive frame 11 slides horizontally on the horizontal drive frame 1, the storage structure 12 slides vertically on the vertical drive frame 11, the clamping member 13 is distributed below the storage structure 12, and the pull rope 131 is fixed between the storage structure 12 and the clamping member 13.

[0080] Specifically, the horizontal drive frame 1 is provided with a structure that drives the vertical drive frame 11 to move horizontally, and the vertical drive frame 11 is provided with a structure that drives the storage structure 12 to move vertically. The storage structure 12 can be selected as an electric hoist that can be purchased on the market.

[0081] When the hoisting structure needs to carry materials into the storage cavity 4, the horizontal drive frame 1 and the vertical drive frame 11 adjust the position of the clamping member 13, so that the clamping member 13 can clamp the materials required for steelmaking. When the clamping member 13 needs to clamp the materials required for steelmaking, the storage structure 12 controls the height of the clamping member 13 through the pull rope 131, so that the clamping member 13 can clamp the materials required for steelmaking.

[0082] After the clamping member 13 clamps the material required for steelmaking, the horizontal drive frame 1 and the vertical drive frame 11 adjust the position of the clamping member 13, so that the clamping member 13 can easily drive the material required for steelmaking into the receiving cavity 4. The clamping member 13 can be selected as an electric mechanical gripper that can be purchased on the market.

[0083] A steelmaking apparatus includes: a steelmaking furnace 3 and a flue gas recovery structure 31;

[0084] The steelmaking furnace 3 is used to collect the material discharged from the receiving chamber 4. The flue gas recovery structure 31 is fixed on one side of the receiving end of the steelmaking furnace 3. When the material discharged from the receiving chamber 4 is put into the receiving end of the steelmaking furnace 3, the flue gas recovery structure 31 collects the flue gas at the receiving end of the steelmaking furnace 3.

[0085] In one possible implementation, a mounting ring 22 is fixed to the receiving end of the steelmaking furnace 3, and an inclined plate 21 is fixed between the mounting ring 22 and the fixing plate 2. The inclined plate 21 is used to guide the material discharged from the receiving cavity 4 to the receiving end of the steelmaking furnace 3, thereby enabling the steelmaking furnace 3 to melt the material discharged from the receiving cavity 4.

[0086] Specifically, in actual use, the steelmaking furnace 3 can melt the materials required for steelmaking. When the materials inside the receiving cavity 4 are fed into the inclined plate 21, the materials can slide into the interior of the steelmaking furnace 3 under the action of gravity, which facilitates the melting of the materials required for steelmaking by the steelmaking furnace 3. The inclined plate 21 can be selected as a corrugated plate that can be purchased on the market. The rectangular groove of the corrugated plate can drive the materials required for steelmaking to be transferred to the interior of the steelmaking furnace 3.

[0087] When materials need to be added to the receiving end of the steelmaking furnace 3, the external computer control system controls the flue gas recovery structure 31 to work. The flue gas recovery structure 31 will drive the heat from the receiving end of the steelmaking furnace 3 to the outside. The staff can connect the heat recovery structure to the emission end of the flue gas recovery structure 31, thereby realizing the recovery and utilization of flue gas inside the steelmaking furnace 3.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
