Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery production technology, and in particular to a slurry transfer tank. Background Technology
[0002] In the production process of lithium-ion batteries, the slurry usually needs to be stored in a transfer tank and then sent to the coating machine for coating. The storage quality of the slurry in the transfer tank is crucial to the next coating process, which will affect the consistency of the appearance, thickness and areal density of the electrode, and thus affect the quality of the lithium-ion battery.
[0003] Currently, the feed inlet of the slurry transfer tank is generally located at the top or top of the tank. When the slurry enters the transfer tank, it falls directly to the bottom, causing air bubbles to form. If no defoaming measures are taken subsequently, defects such as air bubbles and exposed foil often appear on the electrode sheets during coating, resulting in quality abnormalities. In related technologies, agitators are usually used to defoam the slurry, removing air bubbles and thus improving coating quality. However, for high-viscosity slurries, the slurry layer in the transfer tank is relatively thick after the slurry is transported, making it difficult to remove air bubbles through simple agitation. Moreover, this defoaming method is time-consuming, inefficient, and also affects the quality and yield of the coated products. Utility Model Content
[0004] To address the shortcomings of the prior art, this utility model provides a slurry transfer tank, which avoids the problems of time-consuming and inefficient methods of removing air bubbles from slurry through simple stirring.
[0005] The technical effect to be achieved by this utility model is realized through the following technical solution:
[0006] This utility model provides a slurry transfer tank, comprising:
[0007] The tank body has an inlet and an outlet.
[0008] A feed pipe is installed at the feed inlet;
[0009] The discharge pipe is installed at the discharge port; and
[0010] A guide plate is connected to the inner wall of the tank body, and a guide cavity is formed between the guide plate and the inner wall of the tank body. The outlet of the feed pipe is connected to the guide cavity. A guide port is formed between the lower end of the guide plate and the inner wall of the tank body. The guide port is connected to the guide cavity, so that the slurry flowing into the guide cavity through the outlet flows out along the guide port to form a thin layer of slurry and flows down along the inner wall of the tank body.
[0011] In some implementations, the guide plate includes a first blocking wall and a guide wall. The first blocking wall is connected to the inner wall of the tank body, and the guide wall is inclined toward the inner wall of the tank body. The upper end of the guide wall is connected to the first blocking wall, and the lower end of the guide wall forms the guide port between itself and the inner wall of the tank body.
[0012] In this implementation, the slurry flows into the guide cavity through the discharge pipe and is blocked by the first barrier wall, thus flowing down along the first barrier wall and the guide wall. The first barrier wall prevents the slurry from falling directly into the bottom of the tank body and generating bubbles.
[0013] In some implementations, the guide plate further includes a second barrier wall and a third barrier wall. The second barrier wall is connected to one side of the first barrier wall, one side of the guide wall, and the inner wall of the tank body. The third barrier wall is connected to the other side of the first barrier wall, the other side of the guide wall, and the inner wall of the tank body. The second barrier wall and the third barrier wall enclose the two sides of the guide cavity so that the slurry in the guide cavity flows out only along the guide port.
[0014] In some implementations, both the first blocking wall and the guide wall extend circumferentially along the tank body. One side of the first blocking wall is connected to the other side of the first blocking wall, and one side of the guide wall is connected to the other side of the guide wall. One side of the guide cavity is connected to the other side of the guide cavity, so that the slurry in the guide cavity flows out only along the guide port.
[0015] In some implementations, the feed inlet is located at the top of the tank body, the discharge outlet is located at the bottom of the tank body, the guide plate is connected to the upper part of the inner wall of the tank body, the guide plate covers the feed inlet, and the feed pipe passes through the feed inlet so that the discharge outlet of the feed pipe is connected to the guide cavity.
[0016] Alternatively, the feed inlet is located at the top of the tank body, the discharge outlet is located at the bottom of the tank body, the guide plate is connected to the upper part of the inner wall of the tank body, and the feed pipe passes through the feed inlet and the guide plate so that the discharge outlet of the feed pipe is connected to the guide cavity.
[0017] In some implementations, the width of the flow guide is 5-30mm.
[0018] In some implementations, the inner wall of the baffle plate and / or the inner wall of the tank body is coated with an anti-stick coating.
[0019] In some implementations, an air extraction module connected to the interior of the tank body is also included, which can extract air from the interior of the tank body to allow air bubbles in the slurry to escape into the interior of the tank body.
[0020] In some implementations, a slurry circulation module is also included. The slurry circulation module includes a delivery pump and a multi-way valve located on the discharge pipeline. The multi-way valve is located downstream of the delivery pump. The discharge pipeline is connected to the inlet pipeline through the multi-way valve, so that the slurry circulates between the discharge pipeline, the inlet pipeline and the inside of the tank body under the drive of the delivery pump.
[0021] In some implementations, the slurry circulation module further includes a first switching valve and a third switching valve located on the feed pipeline, with the first switching valve located downstream of the multi-way valve and the third switching valve located upstream of the multi-way valve; the slurry circulation module further includes a second switching valve and a fourth switching valve located on the discharge pipeline, with the second switching valve located upstream of the multi-way valve and the fourth switching valve located downstream of the multi-way valve, so that the multi-way valve can switch between a feed state, a circulation flow state, and a discharge state.
[0022] In this implementation, by controlling the opening and closing of four switching valves to form a coordination, the function of the slurry transfer tank can be switched so that it can realize the functions of feeding, internal circulation and discharging.
[0023] In some implementations, a stirring module is also included. The stirring module includes a stirring paddle and a stirring drive. The stirring paddle is installed inside the tank body, and the stirring drive is installed outside the tank body and connected to the stirring paddle. The stirring drive can drive the stirring paddle to rotate and stir the slurry, so that the air bubbles in the slurry can escape into the tank body.
[0024] In some implementations, there are multiple feed pipes, and the outlets of the multiple feed pipes are spaced apart along the circumference of the tank body. The outlets of the multiple feed pipes are connected to one or more of the guide cavities.
[0025] In summary, this utility model has at least the following advantages:
[0026] The slurry transfer tank provided by this utility model has a guide plate on the inner wall of the tank body. The slurry flows into the guide cavity through the discharge pipe, and then flows down along the guide plate and out through the guide port to form a thin layer of slurry before flowing down along the inner wall of the tank body. This avoids the problem of slurry falling directly to the bottom of the tank body and generating air bubbles, and / or the problem of slurry falling directly to the bottom of the tank body and mixing with the original slurry to form air bubbles. Moreover, the formation of a thin layer of slurry makes it easier for the original air bubbles in the slurry to escape. This avoids the problem of long time and low efficiency of simple stirring to remove air bubbles from the slurry, and further ensures the quality and yield of the coated products.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0045] Example 1:
[0046] Please see the appendix Figure 1 ~Appendix Figure 4 The slurry transfer tank of this utility model includes a tank body 1, a feed pipe 2, a discharge pipe 3, and a guide plate 4.
[0047] Please see below. Figure 1 , Figure 1 The diagram illustrates the structural relationship between the tank body 1, the feed pipe 2, the discharge pipe 3, and the guide plate 4 in this embodiment of the present invention. Specifically, the tank body 1 has a feed inlet 11 and a discharge outlet 12; the feed pipe 2 passes through the feed inlet 11; the discharge pipe 3 passes through the discharge outlet 12; the guide plate 4 is connected to the inner wall of the tank body 1, and a guide cavity 4a is formed between the guide plate 4 and the inner wall of the tank body 1; the discharge outlet 21 of the feed pipe 2 is connected to the guide cavity 4a; a guide port 41 is formed between the lower end of the guide plate 4 and the inner wall of the tank body 1, and the guide port 41 is connected to the guide cavity 4a, so that the slurry flowing into the guide cavity 4a through the discharge outlet 21 flows out along the guide port 41 to form a thin layer of slurry and flows down along the inner wall of the tank body 1.
[0048] In this embodiment, the slurry flows in the feed pipe 2. Since the discharge port 21 is connected to the guide cavity 4a, and a guide port 41 is formed between the lower end of the guide plate 4 and the inner wall of the tank body 1, the slurry flows into the guide cavity 4a and out of the guide port 41 to form a thin layer of slurry that then flows down the inner wall of the tank body 1, thereby reducing the generation of bubbles. That is, the guide plate 4 provides a buffer process when the slurry flows into the bottom of the tank body 1, and since the guide port 41 is set downward, it ensures that the slurry flows down the inner wall of the tank body 1 without falling directly into the bottom of the tank body 1. This avoids the problem of slurry falling directly into the bottom of the tank body 1 and generating bubbles, and the problem of slurry falling directly into the bottom of the tank body 1 and mixing with the original slurry to form bubbles. This also avoids the problem that it is difficult to remove bubbles from the slurry by simple stirring when the slurry viscosity is high. It is understandable that when the slurry flows out along the guide port 41 and down the inner wall of the tank body 1, the guide port 41 restricts the thickness of the flowing slurry, causing the slurry to form a thin layer, which facilitates the escape of the original air bubbles in the slurry.
[0049] The aforementioned slurry transfer tank, with a guide plate 4 installed on the inner wall of the tank body 1, allows the slurry to flow into the guide cavity 4a through the outlet 21. The slurry then flows down along the guide plate 4 and out through the guide port 41, forming a thin layer of slurry that flows down the inner wall of the tank body 1. This avoids the problem of slurry falling directly to the bottom of the tank body 1 and generating bubbles, and / or the problem of slurry falling directly to the bottom of the tank body 1 and mixing with the original slurry to form bubbles. Furthermore, the formation of a thin layer of slurry makes it easier for the original bubbles in the slurry to escape, thus avoiding the time-consuming and inefficient method of removing bubbles from the slurry by simple stirring. This further ensures the quality and yield of the coated products.
[0050] In some preferred embodiments, the guide plate 4 includes a first blocking wall 42 and a guide wall 43. The first blocking wall 42 is connected to the inner wall of the tank body 1, and the guide wall 43 is inclined toward the inner wall of the tank body 1. The upper end of the guide wall 43 is connected to the first blocking wall 42, and the lower end of the guide wall 43 forms a guide port 41 between itself and the inner wall of the tank body 1.
[0051] The slurry flows into the guide cavity 4a through the discharge port 21 and is blocked by the first baffle wall 42, thus flowing down along the first baffle wall 42 and the guide wall 43. The first baffle wall 42 prevents the slurry from falling directly into the bottom of the tank body 1 and generating air bubbles. The guide wall 43 guides the slurry out of the guide port 41, preventing the slurry from accumulating in the guide cavity 4a and ensuring that the slurry flows smoothly out of the guide port 41, forming a thin layer of slurry that flows down the inner wall of the tank body 1. Preferably, both the guide plate 4 and the inner wall of the tank body 1 are smooth surfaces to enhance the fluidity of the slurry and prevent the slurry from accumulating on the guide plate 4 or the inner wall of the tank body 1.
[0052] In some preferred embodiments, please refer to Figure 2 , Figure 2 The diagram illustrates the structural relationship between the second blocking wall 44, the third blocking wall 45, and the first blocking wall 42 in this embodiment of the invention. Specifically, the guide plate 4 further includes a second blocking wall 44 and a third blocking wall 45. The second blocking wall 44 is connected to one side of the first blocking wall 42, one side of the guide wall 43, and the inner wall of the tank body 1. The third blocking wall 45 is connected to the other side of the first blocking wall 42, the other side of the guide wall 43, and the inner wall of the tank body 1. The second blocking wall 44 and the third blocking wall 45 are closed at both ends of the guide cavity 4a, so that the slurry in the guide cavity 4a flows out only along the guide port 41. The second blocking wall 44 and the third blocking wall 45 are arranged opposite to each other and together with the first blocking wall 42 form the guide plate 4, so that both ends of the guide plate 4 are sealed to the inner wall of the tank body 1, thereby ensuring that the slurry can only flow out from the guide port 41 after entering the guide cavity 4a, further guaranteeing the reliability of the slurry flowing down the inner wall of the tank body 1.
[0053] In some preferred embodiments, please refer to Figure 3 Both the first blocking wall 42 and the guide wall 43 extend circumferentially along the tank body 1. One end of the first blocking wall 42 is connected to the other end of the first blocking wall 42, and one end of the guide wall 43 is connected to the other end of the guide wall 43. One end of the guide cavity 4a is connected to the other end of the guide cavity 4a, so that the slurry in the guide cavity 4a flows out only along the guide port 41. That is, the guide plate 4 extends circumferentially along the tank body 1. In this way, the length of the guide plate 4 and the guide port 41 is increased, which can more quickly distribute the slurry flowing out of the discharge pipe 21 and make the slurry flow out evenly from the guide port 41.
[0054] In some preferred embodiments, please refer to Figure 1 The inlet 11 is located at the top of the tank body 1, and the outlet 12 is located at the bottom of the tank body 1. A guide plate 4 is connected to the upper part of the inner wall of the tank body 1 and covers the inlet 11. The feed pipe 2 passes through the inlet 11 so that the outlet 21 of the feed pipe 2 is connected to the guide cavity 4a. The slurry flows into the guide cavity 4a through the outlet 21 and is blocked by the guide plate 4, thus flowing down along the guide plate 4, preventing the slurry from falling directly to the bottom of the tank body 1 and generating bubbles.
[0055] Alternatively, please see Figure 4The inlet 11 is located at the top of the tank body 1, and the outlet 12 is located at the bottom of the tank body 1. The guide plate 4 is connected to the upper part of the inner wall of the tank body 1. The feed pipe 2 passes through the inlet 11 and the guide plate 4, so that the outlet 21 of the feed pipe 2 is connected to the guide cavity 4a. The feed pipe 2 passes through the inlet 11 and the guide plate 4 in sequence, so that the outlet 21 is connected to the guide cavity 4a. After the slurry flows into the guide cavity 4a through the outlet 21, part of the slurry is blocked by the inner wall of the tank body 1 and flows down the inner wall of the tank body 1. The other part of the slurry is blocked by the guide plate 4 and flows down the guide plate 4. After the slurry flows out through the guide port 41, it forms a thin layer of slurry and continues to flow down the inner wall of the tank body 1, avoiding the problem of the slurry falling directly into the bottom of the tank body 1 and generating bubbles.
[0056] In some preferred embodiments, the width of the flow inlet 41 is 5-30 mm. This ensures that the slurry can flow smoothly out of the flow cavity 4a, while also ensuring that the slurry forms a thin layer, making it easier for any air bubbles in the slurry to escape, further guaranteeing the quality and yield of the coated product.
[0057] In some more preferred embodiments, the inner wall of the guide plate 4 and / or the inner wall of the tank body 1 is coated with an anti-stick coating. This prevents the slurry from sticking to the guide plate 4 and the tank body 1, thus avoiding the problem of slurry accumulation on the inner wall of the guide plate 4 and / or the tank body 1, and preventing the defoaming effect from being affected by slurry accumulation.
[0058] Example 2:
[0059] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the slurry transfer tank of this utility model. Please refer to the appendix. Figure 5 ~Appendix Figure 6 .
[0060] Please see below. Figure 5 , Figure 5 The diagram illustrates the structural relationship between the air extraction module 5 and the tank body 1 in this embodiment of the invention. Specifically, the slurry transfer tank also includes an air extraction module 5 connected to the interior of the tank body 1. The air extraction module 5 can extract air from the interior of the tank body 1 to make it easier for air bubbles in the slurry to escape into the interior of the tank body 1.
[0061] In this embodiment, the air extraction module 5 continuously extracts air from inside the tank body 1 to reduce the pressure inside the tank body 1, making it easier for air bubbles in the slurry to escape into the tank body 1. These air bubbles are then extracted from inside the tank body 1, achieving a better defoaming effect. Preferably, the air extraction module 5 can be an air extraction pipeline and a negative pressure source. Under the action of the negative pressure source, air is extracted from inside the tank body 1 through the air extraction pipeline. In some embodiments, the negative pressure source can be an air pump or a negative pressure pipeline, etc.
[0062] In some preferred embodiments, please continue to refer to Figure 5 , Figure 5 The diagram illustrates the structural relationship between the discharge pipe 3 and the inlet pipe 2 in this embodiment of the present invention. Specifically, the slurry transfer tank also includes a slurry circulation module 6, which includes a delivery pump 61 and a multi-way valve 62 located on the discharge pipe 3. The multi-way valve 62 is located downstream of the delivery pump 61, and the discharge pipe 3 is connected to the inlet pipe 2 through the multi-way valve 62, so that the slurry circulates between the discharge pipe 3, the inlet pipe 2, and the inside of the tank body 1 under the drive of the delivery pump 61.
[0063] In this embodiment, the flow direction of the slurry is changed between the discharge pipe 3, the feed pipe 2, and the tank body 1 by controlling the flow direction switch of the multi-way valve 62. Specifically, when feeding is required, the feed pipe 2 can be opened and the discharge pipe 3 can be closed by controlling the multi-way valve 62, so that the slurry enters the tank body 1 along the feed pipe 2; when discharging, the discharge pipe 3 can be opened and the feed pipe 2 can be closed, and the delivery pump 61 can be started, so that the slurry inside the tank body 1 flows out along the discharge pipe 3 under the drive of the delivery pump 61; when the slurry inside the tank body 1 reaches a certain volume, the discharge pipe 3 and the feed pipe 2 can be connected by controlling the multi-way valve 62, and the delivery pump 61 can be started, so that the slurry circulates between the discharge pipe 3, the feed pipe 2, and the tank body 1. That is, after the slurry continuously flows out along the guide port 41, a thin layer of slurry is formed. It can also be combined with the air extraction module 5 to remove air bubbles in the slurry, so as to achieve a better defoaming effect.
[0064] In some preferred embodiments, please refer to Figure 6 , Figure 6 The diagram illustrates the structural relationship between the switching valve, the feed pipe 2, and the discharge pipe 3 in this embodiment of the present invention. Specifically, the slurry circulation module 6 further includes a first switching valve 63 and a third switching valve 64 disposed on the feed pipe 2. The first switching valve 63 is located downstream of the multi-way valve 62, and the third switching valve 64 is located upstream of the multi-way valve 62. The slurry circulation module 6 also includes a second switching valve 65 and a fourth switching valve 66 disposed on the discharge pipe 3. The second switching valve 65 is located upstream of the multi-way valve 62, and the fourth switching valve 66 is located downstream of the multi-way valve 62, so that the multi-way valve 62 can switch between a feeding state, a circulating flow state, and a discharge state.
[0065] In this embodiment, by controlling the opening and closing of four switching valves in coordination, the function of the slurry transfer tank can be switched to achieve feeding, internal circulation, and discharging functions. Specifically, the third switching valve 64 and the fourth switching valve 66 are closed, the first switching valve 63 and the second switching valve 65 are opened, and the multi-way valve 62 is controlled to connect the discharge pipeline 3 and the feed pipeline 2. The delivery pump 61 is started, so that the slurry continuously circulates along the feed pipeline 2, the inside of the tank body 1, and the discharge pipeline 3 under the drive of the delivery pump 61. After the slurry continuously flows out along the guide port 41, a thin layer of slurry is formed. It can also be combined with the air extraction module 5 to remove air bubbles in the slurry, which enhances the air bubble removal effect and further ensures the quality and yield of the coated product.
[0066] Furthermore, by closing the second switching valve 65 and the fourth switching valve 66, and opening the first switching valve 63 and the third switching valve 64, the feed pipe 2 is opened by controlling the multi-way valve 62. The slurry flows along the feed pipe 2 into the tank body, thus realizing the feeding operation. Then, by closing the first switching valve 63, the third switching valve 64, and the air extraction module 5, and opening the second switching valve 65 and the fourth switching valve 66, the conveying pump 61 is started. The conveying pump 61 drives the slurry to flow along the discharge pipe 3 to the coating machine, thus realizing the coating material supply.
[0067] Example 3:
[0068] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the slurry transfer tank of this utility model. Please refer to the appendix. Figure 7 ~Appendix Figure 8 .
[0069] Please see below. Figure 7 , Figure 7 The diagram illustrates the structural relationship between the stirring module 7 and the tank body 1 in this embodiment of the present invention. Specifically, the slurry transfer tank further includes a stirring module 7, which includes a stirring paddle 71 and a stirring drive 72. The stirring paddle 71 is installed inside the tank body 1, and the stirring drive 72 is installed outside the tank body 1 and connected to the stirring paddle 71. The stirring drive 72 can drive the stirring paddle 71 to rotate and stir the slurry, so that the air bubbles in the slurry can escape into the tank body 1.
[0070] In this embodiment, the stirring paddle 71 continuously stirs the slurry under the drive of the stirring drive 72, so that the air bubbles in the slurry escape into the tank body 1. It can also be combined with the air extraction module 5 to extract the air bubbles from the tank body 1, thereby improving the defoaming effect and further ensuring the quality and yield of the coated product.
[0071] In some preferred embodiments, please refer to Figure 8There are multiple feed pipes 2, and the outlet ports 21 of the multiple feed pipes 2 are arranged at intervals along the circumference of the tank body 1. The outlet ports 21 of the multiple feed pipes 2 are connected to one or more guide cavities 4a. Due to the multiple feed pipes 2, the efficiency of slurry flowing into the guide cavity 4a through the outlet ports 21 is improved. There are multiple guide plates 4, and the multiple guide plates 4 are arranged at intervals along the circumference of the tank body 1, so that the multiple guide cavities 4a are arranged one-to-one with the multiple outlet ports 21, or the guide plates 4 extend along the circumference of the tank body 1, so that the number of guide cavities 4a is one, and the multiple outlet ports 21 are connected to one guide cavity 4a, so that the slurry flows into the guide cavity 4a through the outlet ports 21, and the slurry flows out along the guide port 41 to form a thin layer of slurry and flows down the inner wall of the tank body 1, which improves the slurry conveying efficiency and ensures the reliability of defoaming. It is understandable that the number of feed pipes 2 can be increased according to the actual defoaming requirements, as long as the slurry output from the feed pipes 2 forms a thin layer of slurry after flowing out of the guide port 41 and flows down along the inner wall of the tank body 1.
[0072] Furthermore, multiple feed pipes 2 are arranged between the guide chamber 4a and the third switching valve 64; the third switching valve 64 and the fourth switching valve 66 are closed, the first switching valve 63 and the second switching valve 65 are opened, and the delivery pump 61 is started so that the slurry enters the tank body 1 along the feed pipe 2 and is then output from the discharge pipe 3. The discharge pipe 3 is connected to the feed pipe 2 through the multi-way valve 62, and then enters the tank body 1 again through the feed pipe 2. This cycle continues, and the air extraction module 5 can be used to continuously extract the air from the tank body 1 to remove air bubbles from the slurry.
[0073] The slurry transfer tank of this utility model has a guide plate 4 set on the inner wall of the tank body 1. The slurry flows into the guide cavity 4a through the discharge pipe 21, and then flows down along the guide plate 4 and out along the guide port 41 to form a thin layer of slurry before flowing down along the inner wall of the tank body 1. This avoids the problem of slurry falling directly to the bottom of the tank body 1 and generating air bubbles, and / or the problem of slurry falling directly to the bottom of the tank body 1 and mixing with the original slurry to form air bubbles. Moreover, the formation of a thin layer of slurry makes it easier for the original air bubbles in the slurry to escape. This avoids the problem of long time and low efficiency of simple stirring to remove air bubbles from the slurry, and further ensures the quality and yield of the coated products.
[0074] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0075] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0076] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
