Description

Technical Field

[0001] The utility model relates to the field of new energy, and in particular to a sampling tool and a positive electrode material production system. Background Art

[0002] During the production of cathode materials, frequent sampling is required for self-inspection and customer inspection. At the same time, since cathode materials have very strict requirements on the foreign matter index of finished products, foreign matter exceeding the standard will affect battery safety and performance, so the introduction of foreign matter needs to be strictly controlled throughout the production process. When sampling finished product packaging, due to the long opening of the inner bag of the ton bag, the sampling personnel need to hold the sampling spoon and extend their arms into the package to scoop the material multiple times, which is easy to introduce foreign matter.

[0003] Generally speaking, the scooping process is as follows: wear disposable gloves before sampling, clean the sampling spoon with dust-free paper, then use a magnetic rod to demagnetize the body and the sampling spoon, and finally hold the spoon handle and reach into the ton bag to scoop the material multiple times. In the packaging process, the sampling personnel will take samples of each package of finished products for self-inspection and customer inspection. The sampling volume is large and the labor intensity of scooping materials multiple times is high. In addition, it is not convenient to bag after sampling using the current sampling tools. The sampling bag opening is small, and the material is easy to spill during the bagging process.

[0004] The existing sampling tools are similar in structure to common kitchen spoons, and mainly consist of a handle and a head. The sampling process has the following problems:

[0005] (1) During the sampling process, the sleeves and gloves of the sampler will rub against the inner bag of the packaging, and foreign matter on the clothes or gloves will fall directly into the ton bag, causing foreign matter to be introduced into the material.

[0006] (2) When taking samples, the sleeves of personnel are easily contaminated by materials, which is inconvenient to clean.

[0007] (3) Each time sampling is performed, a pair of disposable gloves is consumed, which wastes costs.

[0008] (4) The scooping operation is inconvenient and requires high frequency, which results in high labor intensity for employees.

[0009] (5) Due to the small opening of the sampling bag, the material is easily spilled when pouring it into the sampling bag with an ordinary sampling spoon.

[0010] (6) Ordinary sampling spoons take a small amount of samples each time, and each sample needs to be scooped and refilled multiple times.

[0011] In summary, there is an urgent need to solve the problem of foreign matter being easily introduced during the sampling process, while also reducing the consumption of disposable gloves and lowering the sampling cost.

[0012] In view of this, this application is filed. Utility Model Content

[0036] Please refer to Figure 1 and Figure 2 The embodiment of the utility model provides a sampling tool 100 , including a shovel head 110 , a shovel handle 120 , a handle portion 130 and a protective cover 140 .

[0037] It should be noted that the protective cover 140 is used to protect the operator's hands and arms during use to avoid contact with the inner bag of the packaging, thereby reducing the risk of introducing foreign matter during sampling; avoiding the extensive use of disposable gloves and reducing sampling costs; and preventing materials from adhering to clothing and hands during the sampling process, thereby reducing the frequency of employee clothing cleaning.

[0038] The protective cover 140 has a sealing end 141 and an open end 142 opposite to the sealing end 141, the shovel head 110 is connected to one end of the shovel handle 120, the sealing end 141 of the protective cover 140 is connected to the other end of the shovel handle 120, the handle portion 130 has a connecting end and a gripping end opposite to the connecting end, the connecting end of the handle portion 130 is connected to the inside of the protective cover 140, and the gripping end of the handle portion 130 is located inside the protective cover 140. When in use, the operator holds the handle portion 130, and the hand and arm can avoid contact with the inner bag of the package in the protective cover 140, reducing the risk of introducing foreign matter during sampling.

[0039] In some embodiments, the shovel head 110 includes a shovel tip 111 and a shovel bottom 112, the shovel tip 111 is connected to one end of the shovel bottom 112, and the other end of the shovel bottom 112 is connected to one end of the shovel handle 120. When sampling, the shovel tip 111 is inserted into the material, so that the material enters the shovel bottom 112, and the sampling tool 100 is taken out as a whole after the material volume reaches the required amount. When sampling is performed using the shovel head 110 with the shovel tip 111, the sampling method is changed from scooping to shoveling, which makes it easier to insert the material during sampling, saves more effort, and makes it easier to put the material into the bag when bagging, and the material is not easy to spill.

[0040] In some embodiments, the width of the shovel tip 111 gradually decreases from one end close to the shovel bottom 112 to the other opposite end. The shovel tip 111 is triangular, which makes it easier to insert materials when shoveling, saves effort in operation, and makes it easier to put materials into bags without spilling them.

[0041] Furthermore, the shovel tip 111 is inclined upward from one end close to the shovel bottom 112 to the other end opposite thereto, so that after the shovel tip 111 is inserted into the material, the material can fall quickly into the shovel bottom 112 by utilizing the slope.

[0042] Furthermore, the longitudinal section of the shovel bottom 112 is arc-shaped, with a low middle and two sides inclined upward, so that after the material enters the shovel bottom 112, it is not easy to slide, and the material is better stored; cleaning is more convenient, and cleaning without dead ends can be achieved.

[0043] Specifically, the sizes of the shovel tip 111 and the shovel bottom 112 are not limited and can be specifically designed according to the sampling amount to avoid repeated scooping of a sample.

[0044] Furthermore, the shovel handle 120 is rod-shaped with no limit on length, and can be reasonably designed according to the sampling depth. For example, the length of the shovel handle 120 can be 20mm-40mm, such as 20mm, 25mm, 30mm, 35mm, 40mm, etc.

[0045] In some embodiments, the protective cover 140 includes a cylinder 143, one end of which is open, and the other end of which is sealed and connected to the end of the shovel handle 120. When in use, the operator enters the cylinder 143 from the sealed end 141, holds the handle 130 to shovel materials, and uses the cylinder 143 to protect the hands and arms.

[0046] In some embodiments, the cross section of the sealing end 141 of the cylinder 143 is arc-shaped, and the arc-shaped transition makes the manufacturing easier and the connection more stable. The sealing end 141 can be a hemispherical structure, which is convenient for material collection and processing.

[0047] Specifically, the connection positions of the shovel handle 120 and the handle portion 130 and the protective cover 140 correspond. The shovel handle 120 and the handle portion 130 can be an integral structure or two parts, which is not limited here and can be reasonably designed based on the principle of convenient processing.

[0048] In an optional embodiment, the length of the barrel 143 is 25mm-35mm, and the length of the handle 130 is 10mm-20mm. By reasonably designing the lengths of the barrel 143 and the handle 130, the barrel 143 can provide good protection for the hands and arms.

[0049] Specifically, the length of the barrel 143 should be greater than the length of the handle 130, and the difference between the two lengths is preferably more than 15 mm. The length of the barrel 143 can be 25 mm, 28 mm, 30 mm, 32 mm, 35 mm, etc., and the length of the handle 130 can be 10 mm, 12 mm, 15 mm, 18 mm, 20 mm, etc.

[0050] It should be noted that the material of each part of the sampling tool 100 is not limited, and it can be a non-metallic wear-resistant material, and the specific material is not limited here.

[0051] It should be noted that during use, the working principle of the sampling tool 100 is as follows: when sampling, the sampling personnel holds the handle 130 with one hand, inserts the shovel head 110 into the material under the protection of the protective cover 140, and then takes out the material, and aligns the shovel tip 111 with the sampling pocket to load the material.

[0052] The embodiment of the utility model also provides a positive electrode material production system, including a sampling tool 100, and may also include storage equipment, reactors and other equipment. The sampling tool 100 is used to perform sampling in the storage device, which is easy to operate and has a lower sampling cost.

[0053] In summary, the utility model provides a sampling tool and a positive electrode material production system. By improving the sampling tool, improving the shovel head structure, and adding a protective cover, the improved sampling tool has the following advantages:

[0054] (1) During use, the operator holds the handle, and the shovel head and handle enter the package, and uses the shovel head to scoop the material. During this process, the hands and arms are inside the protective cover to avoid contact with the inner bag of the package, reducing the risk of foreign matter introduced during sampling;

[0055] (2) Disposable gloves do not need to be used during the sampling process, which reduces the cost of using disposable gloves;

[0056] (3) Reduce the chances of operators' clothing being contaminated and reduce the frequency of employee clothing cleaning.

[0057] (4) The shovel head is designed in a triangular shape, which makes it easier to insert materials when shoveling, saves effort in operation, and makes it easier to put materials into bags without spilling them.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
