Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a factory wastewater treatment device. Background Technology

[0002] Wastewater treatment is an indispensable part of industrial production, especially in industries such as metallurgy and chemicals. If wastewater containing impurities such as iron oxide is discharged directly without effective treatment, it will cause serious environmental pollution.

[0003] Currently, in the field of industrial wastewater treatment, the common treatment method is to add coagulants, flocculants and other agents to the wastewater. The agents react with the pollutants in the wastewater to generate large particles that are easy to separate, so as to achieve the separation of pollutants from water.

[0004] However, traditional static dosing methods can easily lead to uneven distribution of flocculants and other chemicals, resulting in significant differences in the concentration of chemicals at different depths in the wastewater. This makes it difficult to achieve efficient and uniform mixing of chemicals and wastewater, leading to poor wastewater treatment results.

[0005] The aforementioned technologies suffer from the drawback of uneven distribution of flocculants and other chemicals during wastewater treatment. Summary of the Invention

[0006] In order to improve the problem of uneven distribution of flocculants and other chemicals during wastewater treatment, this application provides a factory wastewater treatment device.

[0007] The wastewater treatment equipment provided in this application adopts the following technical solution: A factory wastewater treatment device includes: a cylindrical body with an opening at the top, an inlet and an outlet; a support column connected to the bottom of the cylindrical body, the axis of the support column coinciding with the axis of the cylindrical body; a dosing mechanism including a sleeve and several blades, the sleeve being movably fitted onto the support column, the blades being circumferentially distributed on the sleeve, the sleeve having a first receiving cavity, and each of the blades having a second receiving cavity, the first receiving cavity and the second receiving cavity being in communication, forming a dosing chamber for holding chemical solution, the dosing chamber having a chemical outlet; and a pushing mechanism including a first pushing member and a second pushing member, both movably fitted onto the support column, the first pushing member being located above the sleeve for pushing the dosing mechanism from top to bottom, and the second pushing member being located below the sleeve for pushing the dosing mechanism from bottom to top, so that the dosing mechanism can move along the support column, and the blades can agitate the wastewater inside the cylindrical body.

[0008] By adopting the above technical solution, the efficiency and quality of wastewater treatment in the factory can be effectively improved. Specifically: the cylinder is used to carry wastewater, allowing it to enter through the inlet and exit through the outlet, facilitating wastewater treatment through the equipment. The top opening also facilitates the operation of the dosing mechanism. The support column provides guidance and support for the dosing mechanism, and the receiving cavity holds the chemical solution, allowing it to be discharged into the wastewater through the outlet for treatment. The first and second pusher components of the pushing mechanism are located above and below the cylinder, respectively. Alternating top-down and bottom-up pushes allow the dosing mechanism to move flexibly on the support column. This agitates the wastewater through the blades and ensures uniform mixing of the chemical at different depths within the wastewater throughout the treatment process, optimizing the wastewater treatment effect. Optionally, the dosing mechanism includes a discharging assembly. The lower end of the sleeve is provided with a discharging port. The discharging assembly includes a first support plate, a first sealing block, and a plurality of first elastic elements. The first support plate is fixedly connected to the first receiving cavity. One end of the first elastic element is connected to the first support plate, and the other end of the first elastic element is connected to the first sealing block. The first sealing block can block the discharging port. The upper end of the second pushing member is provided with a ball bearing assembly. The ball bearing assembly protrudes from the upper end surface of the second pushing member. When the second pushing member pushes the sleeve, the ball bearing assembly pushes against the first sealing block, thereby opening the discharging port.

[0009] By adopting the above technical solution, when the second pushing member pushes the sleeve upward, the ball bearing assembly pushes against the first sealing block, causing the discharge port to open and thus allowing the liquid to be discharged. This design enables the dosing mechanism to perform dosing during its upward movement after moving to the bottom of the cylinder, allowing the liquid to reach the bottom of the wastewater and achieving dosing at the bottom of the wastewater, which helps to improve the uniformity of liquid distribution.

[0010] Optionally, the blade is inclined such that the connecting line between the blade and the sleeve is spirally wound around the outer periphery of the sleeve's axis.

[0011] By adopting the above technical solution, the inclined blade arrangement allows the connection line between the blade and the sleeve to spiral around the outer circumference of the sleeve's axis, effectively reducing the resistance experienced by the blade during mixing and improving mixing efficiency. Simultaneously, this design also enables the dosing mechanism to automatically rotate around the axis of the support column as it moves along the column, further enhancing the uniformity of drug-sewage mixing and the sewage treatment effect.

[0012] Optionally, the pushing mechanism includes a first connecting rope and a winding assembly. The winding assembly is mounted on the cylinder. A first end of the first connecting rope is connected to the first pushing member. A second end of the first connecting rope is wound around the winding assembly through a first reversing assembly. The first connecting rope can pull the first pushing member downward.

[0013] By adopting the above technical solution, the combined use of the first connecting rope and the winding assembly can effectively control the downward movement of the first pushing component, ensuring that the dosing mechanism accurately reaches the bottom of the cylinder for drug delivery. At the same time, this structural design simplifies the mechanical transmission system, reducing the complexity of the equipment and maintenance costs.

[0014] Optionally, the pushing mechanism includes a second connecting rope, the first end of which is connected to the second pushing member, and the second end of which is wound around the winding assembly via a second reversing component. The second connecting rope can pull the second pushing member upward.

[0015] By adopting the above technical solution, the second connecting rope can effectively pull the second pushing member upward, ensuring that the dosing mechanism can move smoothly upward along the support column, thereby making the liquid in the dosing chamber evenly distributed in the sewage and improving the sewage treatment effect.

[0016] Optionally, the winding assembly includes a drive member and a winding shaft. The cylinder is provided with a support platform. The drive member is mounted on the support platform. The output end of the drive member is throttle-connected to one end of the winding shaft. The other end of the winding shaft is rotatably connected to the side wall of the cylinder. The winding shaft is used to wind the first connecting rope and the second connecting rope.

[0017] By adopting the above technical solution, the drive component can precisely control the rotation of the winding shaft, thereby achieving synchronous or asynchronous pulling of the first and second connecting ropes. This design not only improves the stability and accuracy of the vertical movement of the dosing mechanism but also effectively reduces the need for manual operation, enhancing the automation level of the equipment. Simultaneously, the support platform provides a stable mounting foundation for the drive component, ensuring the operational reliability of the entire system.

[0018] Optionally, the pushing mechanism includes a connecting sleeve, which is fitted around the outer periphery of the support column. The two ends of the connecting sleeve are respectively connected to the first pushing member and the second pushing member. A sleeve is fitted around the outer periphery of the connecting sleeve, and both the first connecting rope and the second connecting rope pass through the sleeve.

[0019] By adopting the above technical solution, the connection sleeve makes the linkage between the first and second pushers more stable and reliable, which helps to achieve the pushing effect on the dosing mechanism.

[0020] Optionally, the pushing mechanism includes a first horn and a second horn, both horn-shaped. The smaller end of the first horn with a smaller diameter is connected to the end of the first pushing member away from the sleeve. The larger end of the first horn with a larger diameter extends away from the sleeve. The first horn is used to limit the second connecting rope and accelerate the flow rate of sewage from the larger end to the smaller end of the first horn, so as to impact the first pushing member. The smaller end of the second horn with a smaller diameter is connected to the end of the second pushing member away from the sleeve. The larger end of the first horn with a larger diameter extends away from the sleeve. The second horn is used to limit the first connecting rope and accelerate the flow rate of sewage from the larger end to the smaller end of the second horn (48), so as to impact the second pushing member and reduce the residence time of impurities in the pushing mechanism.

[0021] By adopting the above technical solution, the design of the first and second horn tubes effectively limits the positions of the second and first connecting ropes, preventing excessive deviation during use. Simultaneously, the horn tube's gradually narrowing design significantly accelerates the flow of sewage, generating a greater impact force on the first and second pushing components, ensuring they can complete their up-and-down reciprocating motion more stably and efficiently. Furthermore, this accelerated flow effectively reduces the residence time of impurities within the pushing mechanism, lowering the risk of clogging and improving the overall efficiency and reliability of the sewage treatment equipment.

[0022] Optionally, the blade is provided with a drug injection port, and the drug injection mechanism is provided with a drug injection assembly. The drug injection assembly includes a second support plate, a second sealing block, and a second elastic member. The second support plate is fixedly disposed in the second accommodating cavity. One end of the second elastic member is connected to the second support plate, and the other end of the second elastic member is connected to the second sealing block. The second sealing block can block the drug injection port.

[0023] By adopting the above technical solution, when it is necessary to add medicine, pressing the second sealing block can send the medicine from the medicine inlet into the second receiving cavity. After the medicine is added, the second sealing block is released. At this time, the second sealing block will seal the medicine inlet under the action of the second elastic element to prevent the medicine from leaking.

[0024] Optionally, a maintenance platform is provided around the outer periphery of the cylinder, and the maintenance platform is located above the inlet.

[0025] By adopting the above technical solution, the maintenance platform facilitates inspection and maintenance work by operators during equipment operation, improving work efficiency. Positioning the maintenance platform above the inlet allows operators easier access to the inlet, facilitating observation and cleaning of the water intake, ensuring normal equipment operation. Simultaneously, the maintenance platform facilitates the replenishment of chemicals in the dosing mechanism, reducing operational difficulty.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the dynamic dosing mechanism and the stirring function of the blades, the uniform distribution of the chemical solution in the wastewater is achieved, which increases the probability of contact between the chemical solution and impurities in the wastewater, thereby significantly improving the wastewater treatment effect; 2. The design of the support column allows the dosing mechanism to move up and down inside the cylinder, while the inclined blades reduce movement resistance, enhance stirring efficiency, and effectively avoid the problem of uneven distribution of flocculants and other chemicals caused by traditional static dosing methods. 3. The first and second pusher components of the propulsion mechanism work together to ensure that the dosing mechanism can move stably along the support column, further ensuring the uniform release of the liquid and the full mixing of the wastewater, and solving the problem of separating high-density impurities such as iron oxide from water.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, a factory wastewater treatment device (hereinafter referred to as "the device") is disclosed. The device includes a cylinder 1, a support column 2, a dosing mechanism 3, and a pushing mechanism 4, which are used to evenly distribute flocculant and other chemical solutions in the wastewater within the cylinder 1, thereby optimizing the separation effect of impurities such as iron oxide in the wastewater.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, the cylinder 1 is used to hold sewage. The cylinder 1 has an inlet 11 and an outlet 12, allowing sewage to enter through the inlet 11 and be discharged through the outlet 12 after treatment. The top of the cylinder 1 is open for easy dosing of chemicals by the dosing mechanism 3. The bottom of the support column 2 is connected to the bottom of the cylinder 1, and the axis of the support column 2 coincides with the axis of the cylinder 1. The support column 2 provides guiding support for the dosing mechanism 3. The dosing mechanism 3 includes a sleeve 31 and several blades 32. The sleeve 31 is movably fitted onto the support column 2, and the blades 32 are circumferentially distributed on the sleeve 31. The sleeve 31 has a first receiving cavity 311, and each of the blades 32 has a second receiving cavity 321. The first receiving cavity 311 and the several second receiving cavities 321 are connected, forming a dosing chamber for holding the chemical solution. The blades 32 have outlets 322, allowing the chemical solution to be initially discharged into the sewage for sewage treatment. In this embodiment, the outlet 322 is tilted upwards, allowing the liquid medicine to flow out initially and slowing down the discharge rate to some extent. This ensures that the liquid medicine continues to be discharged after reaching the bottom of the cylinder 1, mitigating the problem of liquid medicine accumulating on the upper layer of wastewater due to excessively fast output speed from the outlet 322. Simultaneously, the diameter of the outlet 322 is made relatively small according to actual needs, so that a large amount of liquid medicine remains in the dosing chamber when it moves to the bottom of the cylinder 1.

[0041] like Figure 3 , Figure 4 and Figure 5 As shown, the pushing mechanism 4 includes a first pushing member 41 and a second pushing member 42, both of which are movably sleeved on the support column 2. The first pushing member 41 is located above the sleeve 31 and is used to push the dosing mechanism 3 from top to bottom; the second pushing member 42 is located below the sleeve 31 and is used to push the dosing mechanism 3 from bottom to top. The pushing mechanism 4 enables the dosing mechanism 3 to move along the support column 2, and the blades 32 can stir the wastewater in the cylinder 1, improving the mixing degree. The first pushing member 41 and the second pushing member 42 of the pushing mechanism 4 are located above and below the sleeve 31, respectively. Through alternating top-down and bottom-up pushing, the dosing mechanism 3 can move flexibly on the support column 2. On the one hand, the blades 32 achieve stirring of the wastewater; on the other hand, it ensures that the drug is uniformly mixed at different depths in the wastewater throughout the treatment process, optimizing the wastewater treatment effect.

[0042] like Figure 3 , Figure 4 and Figure 5As shown, optionally, the blade 32 is inclined, so that the connecting line between the blade 32 and the sleeve 31 is spirally wound around the outer circumference of the axis of the sleeve 31. This inclined arrangement of the blade 32, with the connecting line spirally wound around the outer circumference of the axis of the sleeve 31, effectively reduces the resistance experienced by the blade 32 during stirring, thus improving stirring efficiency. Simultaneously, this design also allows the dosing mechanism 3 to automatically rotate around the axis of the support column 2 due to the pushing force of the wastewater as it moves along the support column 2, further enhancing the uniformity of the mixing of the drug and wastewater and the wastewater treatment effect.

[0043] like Figure 3 , Figure 6 and Figure 7 As shown, optionally, the pushing mechanism 4 includes a first connecting rope 43 and a winding assembly 44. The winding assembly 44 is mounted on the cylinder 1. The first end of the first connecting rope 43 is connected to the first pushing member 41, and the second end of the first connecting rope 43 is wound around the winding assembly 44 through a first reversing assembly. The first connecting rope 43 can pull the first pushing member 41 downward. The cooperative use of the first connecting rope 43 and the winding assembly 44 can effectively control the downward movement of the first pushing member 41, ensuring that the dosing mechanism 3 accurately reaches the bottom of the cylinder 1 for drug delivery. At the same time, this structural design simplifies the mechanical transmission system and reduces the complexity and maintenance cost of the equipment. The side wall of the cylinder 1 is provided with a reversing groove for installing the first reversing assembly and allowing the first connecting rope 43 to move within the reversing groove.

[0044] like Figure 3 , Figure 6 and Figure 7 As shown, optionally, the pushing mechanism 4 includes a second connecting rope 45. The first end of the second connecting rope 45 is connected to the second pushing member 42, and the second end of the second connecting rope 45 is wound around the winding assembly 44 via a second reversing component. The second connecting rope 45 can pull the second pushing member 42 upwards. The second connecting rope 45 can effectively pull the second pushing member 42 upwards, ensuring that the dosing mechanism 3 can smoothly move upwards along the support column 2, thereby evenly distributing the chemical solution in the dosing chamber in the sewage and improving the sewage treatment effect. In this embodiment, both the first reversing component and the second reversing component include several fixed pulleys so that the first connecting rope 43 and the second connecting rope 45 can extend from the dosing mechanism 3 to the winding assembly 44.

[0045] Optionally, the winding assembly 44 includes a drive component 441 and a winding shaft 442. The cylinder 1 is provided with a support platform 13, on which the drive component 441 is mounted. The support platform 13 provides a stable mounting foundation for the drive component 441, ensuring the operational reliability of the entire system. The output end of the drive component 441 is drive-connected to one end of the winding shaft 442, and the other end of the winding shaft 442 is rotatably connected to the side wall of the cylinder 1. The winding shaft 442 is used to wind the first connecting rope 43 and the second connecting rope 45. The drive component 441 can be a motor, which can precisely control the rotation of the winding shaft 442, thereby achieving synchronous or asynchronous pulling of the first connecting rope 43 and the second connecting rope 45. This design not only improves the stability and accuracy of the vertical movement of the dosing mechanism 3, but also effectively reduces the need for manual operation and enhances the automation level of the equipment. In this embodiment, the winding assembly 44 is provided in one set. The second end of the first connecting rope 43 is connected to the second end of the second connecting rope 45 and wound around the winding shaft 442. The outer periphery of the winding shaft 442 is provided with a rough layer. The second ends of the first connecting rope 43 and the second connecting rope 45 can both be flexible ropes made of rough materials such as hemp rope, so that both the first connecting rope 43 and the second connecting rope 45 have sufficient friction with the winding shaft 442. There is no relative sliding between the first connecting rope 43 and the second connecting rope 45 and the winding shaft 442, so that the first pushing member 41 and the second pushing member 42 can rise or fall synchronously through the rotation of the winding shaft 442, reducing the risk of interference caused by the reverse pulling of the first connecting rope 43 and the second connecting rope 45. In other embodiments, two sets of winding assemblies 44 can be provided, with the two sets of winding assemblies 44 corresponding to the first pushing member 41 and the second pushing member 42, respectively.

[0046] like Figure 3 , Figure 4 and Figure 5As shown, optionally, the pushing mechanism 4 includes a connecting sleeve 46, which is fitted around the outer periphery of the support column 2. The two ends of the connecting sleeve 46 are respectively connected to the first pushing member 41 and the second pushing member 42. A sleeve 31 is fitted around the outer periphery of the connecting sleeve 46, and both the first connecting rope 43 and the second connecting rope 45 pass through the sleeve 31. The connecting sleeve 46 improves the overall integrity of the pushing mechanism 4, thereby increasing reliability during vertical movement, reducing friction on the ropes due to relative motion, and extending rope life. The first end of the first connecting rope 43 and the first end of the second connecting rope 45 can both be made of steel wire rope. The tension of the first connecting rope 43 on the first pushing member 41 forms a first angle with the axis of the support column 2, and the tension of the second connecting rope 45 on the second pushing member 42 forms a second angle with the support column 2. The connecting sleeve 46 makes the linkage between the first pushing member 41 and the second pushing member 42 more stable and reliable. To improve the reliability of the pulling action, two connectors can be provided at the first end of the first connecting rope 43 and two connectors can be provided at the first end of the second connecting rope 45, thereby increasing the connection points with the first pusher 41 and the second pusher 42, and the two connectors on the same rope are symmetrically arranged. The tension of the first connecting rope 43 on the first pusher 41 is set at a first angle with the axis of the support column 2, and the tension of the second connecting rope 45 on the second pusher 42 is set at a second angle with the support column 2. Both the first and second angles change periodically, causing the dosing mechanism 3 to be in an inclined state, which helps to cause the blade 32 to rotate due to uneven force, thereby improving the degree of stirring.

[0047] like Figure 3 , Figure 4 and Figure 5 As shown, optionally, the pushing mechanism 4 includes a first horn-shaped tube 47 and a second horn-shaped tube 48. The smaller end of the first horn-shaped tube 47 is connected to the end of the first pushing member 41 away from the sleeve 31, and the larger end of the first horn-shaped tube 47 extends away from the sleeve 31. The first horn-shaped tube 47 is used to limit the second connecting rope 45 and accelerate the flow rate of sewage from the larger end to the smaller end of the first horn-shaped tube 47, thereby impacting the first pushing member 41. The smaller end of the second horn-shaped tube 48 is connected to the end of the second pushing member 42 away from the sleeve 31, and the larger end of the first horn-shaped tube 47 extends away from the sleeve 31. The second horn-shaped tube 48 is used to limit the first connecting rope 43 and accelerate the flow rate of sewage from the larger end to the smaller end of the second horn-shaped tube 48, thereby impacting the second pushing member 42 and reducing the residence time of impurities in the pushing mechanism 4.

[0048] The design of the first horn tube 47 and the second horn tube 48 effectively limits the position of the first connecting rope 43 and the second connecting rope 45, preventing excessive deviation during use. Simultaneously, the horn tube's gradually narrowing design significantly accelerates the flow of sewage, generating a greater impact force on the first and second pushing members 41 and 42, ensuring more stable and efficient up-and-down reciprocating motion. Furthermore, this accelerated flow effectively reduces the residence time of impurities within the pushing mechanism 4, lowering the risk of clogging and improving the overall efficiency and reliability of the sewage treatment equipment.

[0049] like Figure 3 , Figure 4 and Figure 8 As shown, optionally, the dosing mechanism 3 includes a discharging assembly 33, with a discharging port at the lower end of the sleeve 31. The discharging assembly 33 includes a first support plate 331, a first sealing block 332, and several first elastic members 333. The first support plate 331 is fixedly connected to the first receiving cavity 311. One end of each first elastic member 333 is connected to the first support plate 331, and the other end is connected to the first sealing block 332. The first sealing block 332 can block the discharging port. The upper end of the second pushing member 42 is provided with a ball assembly 421, which protrudes from the upper surface of the second pushing member 42. When the second pushing member 42 pushes the sleeve 31, the ball assembly 421 pushes the first sealing block 332, thereby opening the discharging port.

[0050] When the second pusher 42 pushes the sleeve 31 upward, the ball assembly 421 pushes against the first sealing block 332, opening the discharge port and allowing the liquid to be discharged. This design allows the dosing mechanism 3 to dosing during its ascent after moving to the bottom of the cylinder 1, ensuring the liquid reaches the bottom of the wastewater and improving the uniformity of liquid distribution. The discharge port is used for further discharging of liquid from the outlet 322, and its flow rate is greater than that of the outlet 322. The ball assembly 421 includes a mounting groove on the upper surface of the second pusher 42 and several balls. The balls roll within the mounting groove to reduce friction on the dosing mechanism 3, allowing it to rotate freely.

[0051] like Figure 3 , Figure 4 and Figure 9As shown, optionally, the blade 32 is provided with a dosing port, and the dosing mechanism 3 is provided with a dosing assembly 34. Since wastewater enters the dosing chamber during the dosing process, clean water can be poured into the dosing chamber through the dosing port before adding more medication to improve the cleanliness of the dosing chamber. The dosing assembly 34 includes a second support plate 341, a second sealing block 342, and a second elastic element 343. The second support plate 341 is fixedly disposed within the second receiving cavity 321. One end of the second elastic element 343 is connected to the second support plate 341, and the other end is connected to the second sealing block 342, which can seal the dosing port. When medication needs to be added, pressing the second sealing block 342 allows the medication to be fed from the dosing port into the second receiving cavity 321. After dosing is completed, releasing the second sealing block 342 causes it to seal the dosing port under the action of the second elastic element 343, preventing medication leakage. Both the first elastic element 333 and the second elastic element 343 can be springs.

[0052] like Figure 3 As shown, optionally, a maintenance platform 14 is provided around the outer periphery of the cylinder 1. The maintenance platform 14 is located above the inlet 11, reducing operator interference with wastewater input and improving safety. The maintenance platform 14 facilitates inspection and maintenance by operators during equipment operation, improving work efficiency. Positioning the maintenance platform 14 above the inlet 11 allows operators easier access to the inlet 11, facilitating observation and cleaning of the incoming water, ensuring normal equipment operation. Simultaneously, the maintenance platform 14 facilitates the replenishment of chemicals in the dosing mechanism 3, reducing operational difficulty.

[0053] Understandably, the equipment also includes necessary structures for connection, support, drive, positioning, limiting, sealing and control functions to enable the equipment to operate normally; the shape, size, material and quantity of each part of the equipment can be determined as needed to achieve the corresponding functions.

[0054] The implementation principle of a factory wastewater treatment device in this application embodiment is as follows: through the dynamic dosing of the dosing mechanism 3 and the stirring function of the blades 32, the uniform distribution of the chemical solution in the wastewater is achieved, the contact probability between the chemical solution and impurities in the wastewater is increased, thereby improving the wastewater treatment effect.

[0055] 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.
