Description

Technical Field

[0001] This invention belongs to the field of feed machinery technology, specifically relating to an integrated conditioning and preservation machine. Background Technology

[0002] Conditioners and preservers, as key equipment in conditioning systems, are increasingly valued by feed manufacturers. In the conditioning process, the conditioner is located above the preserver, occupying too much vertical space. To achieve higher maturation and sterilization effects, the cylinders of conditioning and preservers are becoming larger, with more and more layers. While improving conditioning and preservement effects, this also continuously occupies vertical space, increasing plant construction and equipment maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated conditioning and preservation machine to solve the technical problems of existing conditioners being located above preservation machines, occupying a large amount of height space, and having high costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a quality conditioning and preservation integrated machine, comprising:

[0005] The quality assurance section includes the quality assurance chamber;

[0006] A conditioning section is arranged side by side with the preservation section. The conditioning section includes a conditioning chamber and a conditioning rotor assembly disposed within the conditioning chamber. The conditioning chamber is connected to the preservation chamber. A material feeding component is disposed on the conditioning rotor assembly. The conditioning rotor assembly drives the material feeding component to rotate, thereby conveying the material from the conditioning section to the preservation section.

[0007] In this invention, the rotors for the conditioning and preservation processes are arranged horizontally side-by-side, working collaboratively to achieve material transfer while reducing vertical space requirements. This facilitates process layout, saves space, and significantly reduces plant costs and subsequent maintenance costs. This invention is an integrated conditioning and preservation machine, possessing both conditioning and preservation functions to achieve the desired material conditioning and preservation effects.

[0008] To address the technical problem of insufficient material filling in the conditioning chamber, this invention employs the following technical solution: the conditioning rotor assembly includes a conditioning shaft and a conveying component mounted on the conditioning shaft. First reverse baffle assemblies are spaced apart on the conditioning shaft where the conveying component is located. These first reverse baffle assemblies are positioned opposite to the material movement direction driven by the conveying component. The first reverse baffle assemblies are used to improve the material filling degree of the conditioning chamber. This invention utilizes the first reverse baffle assemblies to prevent material from moving forward along the direction from the discharge end to the feed end, effectively ensuring the material filling degree within the conditioning chamber.

[0009] To address the technical problem of low reverse material conveying efficiency in the first reverse baffle assembly, this invention employs the following technical solution: the working area of ​​the first reverse baffle assembly is adjustable. This invention can increase the working area of ​​the first reverse baffle assembly, improve its reverse material conveying efficiency, and further ensure the material filling degree within the conditioning chamber.

[0010] To address the technical problem of adjusting the working area of ​​the first reverse baffle assembly, this invention employs the following technical solution: the first reverse baffle assembly includes a spirally arranged baffle base plate, the outer circumference of which may be provided with an extension plate; a side extension plate may be provided on the side of the baffle base plate. The extension plate and the side extension plate are used to increase the working area of ​​the first reverse baffle assembly. Extension portions and / or side extension portions can be added as needed, providing three ways to increase the working area of ​​the first reverse baffle assembly, offering great flexibility and selectivity.

[0011] To address the technical problem of low material feeding efficiency leading to material accumulation and blockage, this invention employs the following technical solution: A second reverse baffle assembly is spaced apart on the conditioning rotor where the feeding component is located. This second reverse baffle assembly cooperates with the feeding component to transport the material from the conditioning section to the preservation section. When the material reaches the end of the conditioning section, the feeding component at the end of the conditioning rotor, in conjunction with the second reverse baffle assembly, can quickly feed the material into the preservation section. This results in smooth material transport, high transport efficiency, and prevents material accumulation and blockage.

[0012] To solve the technical problem of how to implement the cooperating material feeding assembly and the second reverse baffle assembly, the present invention adopts the following technical solution: the material feeding assembly includes a first material feeding plate and a second material feeding plate; the first material feeding plate and the second material feeding plate are arranged in opposite directions;

[0013] The second reverse baffle assembly includes a second reverse baffle one and a second reverse baffle two; the second reverse baffle one and the second reverse baffle two are respectively disposed on both sides of the conditioned rotor, and the working area of ​​the second reverse baffle one and the second reverse baffle two is adjustable.

[0014] The material enters the tail end of the conditioning section, and under the action of the tail material feeding assembly and the second reverse baffle assembly, the material enters the preservation section. The material feeding assembly consists of two bent material feeding plates; the baffle base plate of the second reverse baffle assembly can be appropriately supplemented with a baffle extension plate and a baffle side extension plate to increase the working area and ensure the material feeding effect.

[0015] To solve the problem of steam backflow, the present invention adopts the following technical solution: a steam jacket assembly is provided on the conditioning chamber and / or the preservation chamber, and a check structure is provided on the steam jacket assembly to prevent steam backflow, thereby solving the steam backflow problem in the conditioning section.

[0016] To address the technical problem of how to implement the check valve structure, the present invention adopts the following technical solution: the check valve structure includes a valve body, and an elastic plug is provided inside the valve body. When the steam pressure is greater than the force of the elastic plug, the check valve structure opens, and steam enters the heating and conditioning chamber or the preservation chamber; when the steam pressure is less than the force of the elastic plug, the check valve structure closes to prevent steam from flowing back from the jacket of the conditioning chamber or the preservation chamber.

[0017] To address the technical problem of fixed and unadjustable material conveying efficiency, this invention employs the following technical solution: the material conveying component on the tempering rotor is a paddle assembly, comprising several helically arranged material conveying paddles, the installation angle of which is adjustable. The intermediate conveying section uses adjustable-direction paddles; by adjusting the installation angle of the paddles, the material conveying efficiency can be controlled, allowing the material to continuously move along the material flow direction under the action of the paddles.

[0018] To address the technical problem of organic head material in the material, this invention adopts the following technical solution: a feed inlet is provided on the conditioning chamber, and a feed dispersing component is provided on the conditioning rotor near the feed inlet of the conditioning chamber to disperse the head material in the incoming material. The feed inlet of the rotor in the conditioning process adopts a dispersing bar structure to ensure that the material is free of organic head material.

[0019] To address the technical problem of condensate accumulation inside the rotor, which is used as a steam heating structure, the present invention adopts the following technical solution: a preservation rotor assembly is provided inside the preservation chamber, the preservation rotor assembly includes a preservation rotor and a material conveying component provided on the preservation rotor, and the preservation rotor is connected to the steam supply assembly via a steam pipe;

[0020] A condensate return auger is provided on the inner wall of the quality preservation rotor, and a condensate return structure is provided on the quality preservation rotor. The condensate return auger is used to push the condensate inside the quality preservation rotor back towards the condensate return structure and discharge the condensate inside the quality preservation rotor.

[0021] Steam enters the rotor to heat it. The steam condenses to form condensate. A condensate return auger is added inside the rotor in the quality preservation section. This auger is a reverse auger. When the equipment is running, the reverse auger pushes the condensate inside the rotor back into the condensate return pipe, thus discharging the condensate inside the rotor.

[0022] To solve the technical problem of how to install the condensate return structure, the present invention adopts the following technical solution: the condensate return structure is sleeved outside the steam inlet pipe, and the condensate return structure is coaxially arranged with the steam inlet pipe.

[0023] To address the technical problem of insufficient material filling in the preservation chamber, this invention employs the following technical solution: a reverse baffle assembly is installed in the middle of the preservation rotor to provide directional material movement and improve the material filling within the preservation chamber.

[0024] To solve the technical problem of sealing at the operating door, the present invention adopts the following technical solution: an operating door is provided on the conditioning chamber and the preservation chamber respectively, and a sealing structure is provided on the operating door.

[0025] To address the technical problem of how to achieve a sealing structure, the present invention adopts the following technical solution: the sealing structure includes a first sealing element disposed on the inner side of the operating door. The first sealing element is fixed to the inner wall of the tempering operating door. When the operating door is closed, the inner sealing strip is positioned between the operating door and the tempering chamber and is pressed together to form a first seal.

[0026] To further address the technical issue of sealing, this invention employs the following technical solution: the sealing structure further includes a second sealing element. A boss is provided on the inner wall of the operating door, and the second sealing element is provided on the surrounding side walls of the boss. The second sealing element is embedded in a sealing groove of the operating door. When the operating door is closed, the side-embedded sealing strip fits against the side wall of the cylinder opening, preventing material from entering the gap between the operating door and the inner cylinder, and also preventing steam and moisture from flowing out, thus forming a second seal. This invention employs a double-sealing structure for the operating door, achieving equipment sealing through the double sealing strips on the operating door.

[0027] To address the problem of uneven material distribution in the preservation chamber, this invention employs the following technical solution: a discharge port is provided on the preservation chamber, and a material dispersing component is installed on the preservation rotor near the discharge port to disperse the material and discharge it to the discharge port of the preservation chamber. The material dispersing component disperses the material, preventing accumulation at the discharge port and ensuring uniform material distribution.

[0028] To address the technical problem of how to implement the material dispersing component, this invention adopts the following technical solution: the material dispersing component includes a dispersing ring and a dispersing and pushing plate, which are sequentially arranged on the quality-preserving rotor along the discharge direction. The dispersing ring and the dispersing and pushing plate disperse the material, preventing material accumulation at the discharge port and ensuring uniform discharge. Attached Figure Description

[0054] The invention will now be further described with reference to the accompanying drawings.

[0055] like Figure 1-3 As shown, the integrated conditioning and preservation machine 10 includes a preservation section and a conditioning section. The conditioning section includes a conditioning chamber 100. A feed inlet 101 is provided on one side of the conditioning chamber 100. A conditioning rotor assembly is installed inside the conditioning chamber 100. The conditioning rotor assembly is divided into a feeding section, a conveying section, and a bulk material section according to the material flow direction. The feeding section conveys material forward in both forward and reverse rotation; the conveying section and the bulk material section convey material forward in both forward rotation.

[0056] Please refer to Figure 4-7 The quenching and tempering rotor assembly includes a quenching and tempering shaft 102, with both ends supported on bearing seats. A quenching and tempering drive mechanism 104 drives and connects to the quenching and tempering shaft 102. A material conveying component 103 is provided on the quenching and tempering shaft 102. The material conveying component 103 can be a paddle assembly, including several helically arranged material conveying blades, the installation angle of which is adjustable. The material conveying component 103 can also be a material conveying auger.

[0057] In one embodiment, in order to ensure the material temperature in the conditioning chamber, the conditioning shaft 102 adopts a hollow structure, and a steam inlet pipe 108 is connected to the conditioning shaft 102.

[0058] To improve the material filling rate of the conditioning chamber, a first reverse baffle assembly 120 is provided at intervals on the conditioning shaft where the conveying component is located. The first reverse baffle assembly 120 drives the material to move in the opposite direction to the material movement direction driven by the conveying component 103. Specifically, the first reverse baffle assembly includes a spirally arranged baffle base plate 121.

[0059] To further improve the material filling degree of the conditioning chamber, the working area of ​​the first reverse baffle assembly 120 is adjustable. Specifically, an extension plate 122 may be provided on the outer circumference of the baffle base plate 121; a side extension plate 123 may be provided on the side of the baffle base plate. The extension plate and the side extension plate are used to increase the working area of ​​the first reverse baffle assembly.

[0060] To ensure stable material temperature within the conditioning chamber, a steam jacket assembly 400 is installed on the conditioning chamber.

[0061] Please refer to Figure 8-9 To prevent steam backflow, a check structure 410 is provided on the steam jacket assembly.

[0062] The check valve 410 includes a valve body 411, within which a resilient plug is installed. The resilient plug includes a resilient element 412 and a plug 413 connected together. When the steam pressure is greater than the force of the resilient plug, the check valve opens, allowing steam to enter the heating and conditioning chamber. When the steam pressure is less than the force of the resilient plug, the check valve closes, preventing steam from flowing back from the conditioning chamber jacket.

[0063] To ensure the quality preservation effect of tempering, the tempering section also adopts the form of electric heating plate 600 with electric heating elements pasted on the outside of the tempering chamber.

[0064] A feeding dispersing assembly 107 is installed on the conditioning shaft 102 near the feed inlet 101 of the conditioning chamber 100 to disperse the die head material in the feed inlet of the conditioning chamber. Preferably, the feeding dispersing assembly 107 includes a mounting sleeve and dispersing rods. The mounting sleeve can be an integral structure or a separate structure. The dispersing rods are radially welded to the mounting sleeve and are evenly distributed on the mounting sleeve.

[0065] A dispersing component 108 is installed on the conditioning shaft 102 of the feed inlet 101, which is far away from the conditioning chamber 100, to disperse the conditioning material and facilitate the material feeding component to feed the material evenly.

[0066] Please refer to Figure 13-14 A tempering operation door 105 is installed on the tempering chamber 100. Preferably, the tempering operation door 105 has an arc-shaped plate structure. A boss 1051 is provided on the inner wall of the tempering operation door 105.

[0067] A sealing structure 500 is provided on the tempering operation door 105. A first sealing element 510, namely the inner edge sealing strip, is fixed to the inner side of the door edge of the tempering operation door 105. The inner edge sealing strip is fixed to the inner wall of the tempering operation door. When the operation door is closed, the inner edge sealing strip is located between the operation door and the tempering chamber and is pressed tightly to form a first seal.

[0068] To further improve the sealing effect, mounting grooves are machined on the four sides of the boss 1051. The second sealing element 502, namely the side-embedded sealing strip, is placed in the mounting groove. The side-embedded sealing strip is embedded in the sealing groove of the operating door. When the operating door is closed, the side-embedded sealing strip fits against the side wall of the cylinder opening, so that materials will not enter the gap between the operating door and the inner cylinder, and steam and moisture will also be prevented from flowing out, forming a second seal.

[0069] The present invention utilizes a first sealing element 501 and a second sealing element 502 to form an operating door sealing structure 500, thereby forming a double-sealed operating door and improving the sealing effect.

[0070] Please refer to Figure 1-4 The preservation section and the conditioning section are arranged side by side. The preservation section includes a preservation chamber 200. The preservation chamber 200 is connected to the conditioning chamber 100, specifically, the discharge end of the conditioning chamber 100 is connected to the feed end of the preservation chamber 200. The preservation chamber 200 is provided with a discharge port 206. The discharge port 206 of the preservation chamber 200 and the feed port 101 of the conditioning chamber 100 are located on the same side of the integrated conditioning and preservation machine 10.

[0071] Please refer to Figure 10-12 A quality preservation rotor assembly is installed inside the quality preservation chamber 200, and the quality preservation rotor assembly is arranged parallel to the quality preservation rotor assembly. The quality preservation rotor assembly includes a quality preservation shaft 202. A material conveying component 203 is provided on the quality preservation shaft 201.

[0072] In one embodiment, in order to ensure the material temperature in the preservation chamber, the preservation shaft 202 adopts a hollow structure, and a steam inlet pipe 207 is connected to the preservation shaft 201.

[0073] To improve the material conveying speed at the connection between the conditioning and preservation chambers, a material feeding assembly 110 is installed on the conditioning rotor 101. Specifically, the material feeding assembly 110 includes a first feeding plate 111 and a second feeding plate 112, both of which are bent. The bending directions of the first feeding plate 111 and the second feeding plate 112 are opposite. The conditioning rotor assembly drives the material feeding assembly to rotate, conveying the material from the conditioning section to the preservation section.

[0074] To further improve material conveying efficiency, a second reverse baffle assembly is installed on the conditioning shaft 102 where the material feeding assembly 110 is located. The second reverse baffle assembly cooperates with the material feeding assembly 110 to convey the material from the conditioning section to the preservation section.

[0075] The second reverse baffle assembly on the quenching rotor, where the feeding assembly is located, includes a first reverse baffle 124 and a second reverse baffle 125; the first reverse baffle 124 and the second reverse baffle 125 are respectively disposed on both sides of the quenching rotor shaft. Extended plates and side plates can be installed on the first reverse baffle 124 and the second reverse baffle 125 to increase their working area.

[0076] The material enters the tail end of the conditioning section, and under the action of the tail material feeding assembly and the second reverse baffle assembly, the material enters the preservation section. The material feeding assembly consists of two bent material feeding plates; the baffle base plate of the second reverse baffle assembly can be appropriately supplemented with a baffle extension plate and a baffle side extension plate to increase the working area and ensure the material feeding effect.

[0077] In one embodiment, in order to observe the real-time material condition at the connection between the preservation chamber 200 and the conditioning chamber 100, an observation window 201 is designed on the preservation chamber 200, and the observation window 201 and the discharge port 206 are located at both ends of the preservation chamber 200.

[0078] In one embodiment, in order to ensure the material temperature in the preservation chamber, the preservation shaft 202 adopts a hollow structure, and a steam inlet pipe 207 is connected to the preservation shaft 201.

[0079] In one embodiment, a condensate return structure 300 is connected to the preservation rotor 201 to drain the condensate inside. The condensate return structure 300 includes a condensate return auger 310 and a condensate return pipe 320. The condensate return auger 310 is disposed on the inner wall of the preservation rotor 201. The rotation direction of the condensate return auger 310 is opposite to the rotation direction of the conveyor 203 on the preservation rotor 201. The condensate return auger is used to push the condensate inside the preservation rotor back towards the condensate return structure, thereby draining the condensate from the preservation rotor.

[0080] Specifically, the condensate return pipe 320 includes a horizontal pipe 321 and a vertical pipe 322. The horizontal pipe 321 is sleeved outside the steam inlet pipe 207, and the horizontal pipe 321 and the steam inlet pipe 207 are coaxially arranged. The horizontal pipe 321 is preferably a stepped pipe.

[0081] In one embodiment, in order to improve the material filling degree in the preservation chamber, a reverse baffle assembly 220 is provided on the preservation shaft 202 where the conveyor 203 is located to provide material directional movement.

[0082] Specifically, the reverse baffle assembly 220 drives the material to move in the opposite direction to the material movement direction driven by the conveyor 203. Preferably, the reverse baffle assembly 220 includes helically arranged blades. The blades are spaced apart.

[0083] Please refer to Figure 13-14 In one embodiment, a preservation operation door 205 is provided on the preservation cavity, and a boss 2051 is provided on the inner wall of the operation door 205. A sealing structure 500 is provided on the operation door 205. The sealing structure 500 includes a first sealing element 510, which is provided on the inner side of the door edge of the operation door 205.

[0084] In one embodiment, to further improve the sealing effect of the preservation cavity, a second sealing element 502 is provided on the surrounding sidewalls of the boss 2051. The first sealing element 501 and the second sealing element 502 constitute the operating door sealing structure 500.

[0085] A conditioning operation door 105 is installed on the conditioning chamber 200. Preferably, the conditioning operation door 105 has an arc-shaped plate structure. A boss 1051 is provided on the inner wall of the conditioning operation door 105.

[0086] A sealing structure 500 is provided on the shelf-life operation door 205. A first sealing element 510, namely the inner edge sealing strip, is fixed to the inner side of the door edge of the shelf-life operation door 205. The inner edge sealing strip is fixed to the inner wall of the shelf-life operation door. When the shelf-life operation door is closed, the inner edge sealing strip is located between the shelf-life operation door and the shelf-life cavity and is pressed tightly to form a first seal.

[0087] To further improve the sealing effect, mounting grooves are machined on the four sides of the boss 2051. The second sealing element 502, namely the side-embedded sealing strip, is placed in the mounting groove. The side-embedded sealing strip is embedded in the sealing groove of the preservation operation door. When the operation door is closed, the side-embedded sealing strip is in contact with the side wall of the cylinder opening, so that the material will not enter the gap between the preservation operation door and the opening of the preservation cavity, and at the same time, it will prevent steam and moisture from flowing out, forming a second seal.

[0088] The quality preservation section of the integrated quality preservation machine of the present invention utilizes a first sealing element 501 and a second sealing element 502 to form an operating door sealing structure 500, thereby forming a double-sealed operating door and improving the sealing effect.

[0089] In one embodiment, in order to break up the material and discharge it to the outlet of the preservation chamber, a discharge breaking assembly 210 is installed on the preservation rotating shaft 202 near the outlet to break up the material and discharge it to the outlet of the preservation chamber.

[0090] Specifically, the discharge dispersing assembly 210 includes a dispersing ring 211 and a dispersing and feeding plate 212, which are arranged sequentially on the quality-preserving rotor along the discharge direction.

[0091] In one embodiment, to ensure stable material temperature within the conditioning chamber, a steam jacket assembly is installed on the preservation chamber for heating the material. For better conditioning and preservation effects, the preservation section can also employ an electric heating jacket with externally attached heating elements.

[0092] To ensure stable material temperature within the conditioning chamber, a steam jacket assembly 400 is installed on the conditioning chamber.

[0093] To prevent steam backflow, a check structure is installed at the steam inlet of the steam jacket assembly. This structure consists of a spring and a check plug. The steam one-way check device achieves unidirectional steam flow through a spring, valve core, and valve body, preventing material from flowing back into the steam pipeline.

[0094] The check valve structure 410 includes a valve body 413, within which a resilient plug is installed, comprising an elastic element 412 and the plug 413. When the steam pressure exceeds the force of the resilient plug, the check valve structure opens, allowing steam to enter the heating and preservation chamber. When the steam pressure is less than the force of the resilient plug, the check valve structure closes, preventing steam from flowing back from the preservation chamber interlayer. When steam is supplied, the resilient plug is stressed, compressing the spring and separating the resilient plug from the retaining ring, allowing high-temperature steam to enter the conditioning section through the gap. When there is no steam or the internal pressure exceeds the external pressure, the resilient plug and retaining ring close, preventing material backflow.

[0095] This invention relates to an integrated conditioning and preservation machine, comprising a preservation and discharge section. This structure includes a condensate return system, an auger conveyor, a reverse baffle assembly, a dispersing ring, and a dispersing and pushing plate. Steam enters the rotor to heat it, and the steam condenses to form condensate. During preservation operation, a reverse auger is added inside the rotor. During operation, the reverse auger pushes the condensate inside the rotor back towards the condensate return system, thus discharging the condensate. Material enters the preservation section from the conditioning section, and is heated by steam passing through the steam jacket and inside the rotor. The material moves forward continuously under the action of the auger. The reverse baffle assembly facilitates the reverse movement of the material, increasing the filling degree of the cylinder. The material passes through the dispersing ring and dispersing and pushing plate to uniformly enter the next process.

[0096] The conditioning process rotor inlet adopts a dispersing bar structure to ensure that the material is free of machine head material. Semi-circular augers are added at intervals in the middle to block the material from moving forward, increasing the equipment's fullness. A bent material-pushing plate at the tail of the baffle plate conveys the material from the conditioner to the retainer. The retaining process rotor has reverse augers at intervals in the middle to ensure the material is pushed back, guaranteeing the fullness of the retaining process. A dispersing ring at the tail ensures that the material does not clump before entering the next process. This invention forms an integrated conditioning and retaining machine, consisting of a conditioning feeding section and a retaining discharging section, with two conditioning and retaining rotors arranged horizontally side-by-side.

[0097] Working process of the integrated conditioning and preservation machine:

[0098] During the operation of the conditioning section, the dispersing bar in the rotor feeding section of the conditioning section can disperse the head material in the incoming material; the intermediate conveying section uses adjustable direction blades to make the material move continuously along the material flow direction under the action of the blades, and at the same time, the first reverse baffle assembly in the intermediate conveying section ensures the material filling degree; when the material runs to the tail of the conditioning section, the material pushing assembly at the tail of the conditioning rotor, in conjunction with the second reverse baffle assembly, can push the material into the preservation section;

[0099] When the material enters the preservation section, it is conveyed forward by the rotation of the spiral rotor. An adjustable reverse baffle on the preservation rotor ensures the material fills the cavity. Depending on the material fill level, additional baffle extension plates or side baffles can be added to extend the working area of ​​the baffle base plate. At the tail end of the preservation section, the material is propelled to the next stage by the tail-end material distribution ring and material feeding plate.

[0100] Material enters the conditioning and preservation integrated machine through the conditioning feed inlet. Driven by the rotation of the conditioning feed cylinder rotor, the material is conveyed forward. At the same time, a first reverse baffle assembly is configured on the conditioning rotor to ensure the material filling of the conditioning cylinder. A material guide plate structure is set at the connection between the conditioning feed cylinder and the preservation discharge cylinder. The rotating material guide plate guides the material to be conveyed from the conditioning feed cylinder to the preservation discharge cylinder. The material in the preservation discharge cylinder is conveyed forward by the rotation of the preservation rotor and finally reaches the discharge port of the conditioning and preservation integrated machine. Under the dispersing action of the dispersing ring and the plate at the discharge port, the material can be evenly fed to other equipment, such as a pellet mill.

[0101] The above embodiments are only for illustrating the technical features and concepts of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made according to the spirit and embodiments of the present invention should be covered within the scope of protection of the present invention.
