Description

Technical Field

[0001] The present invention relates to the technical field of raw material sample preparation, in particular to a tool and method for preparing raw meal samples in the sintering process. Background Art

[0002] In the sintering process of the alumina industry, it is necessary to fry the slurry samples of alkali red mud, proportioning slurry, and qualified slurry into solid samples for detection to monitor and adjust the contents of various elements such as CaO, Na2O, Al2O3, SiO2, Fe2O3, TiO2, MgO, and K2O in the process materials. However, the existing pots and spatulas do not meet the requirements for frying samples.

[0003] Considering the volume and shape of the pot and spatula: When preparing samples, only 10-20 g of solid samples need to be fried. The volume of ordinary pots and spatulas is too large and too heavy, which causes a burden during the operation. Moreover, some pots are flat-bottomed, and the slurry is easy to spread after being poured in, resulting in the inability to quickly shovel up all the dried samples with a spatula after drying. In addition, the large area of the pot is not easy to clean. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a tool and method for preparing raw meal samples in the sintering process. The inner and outer surfaces of the frying pan are both arc-shaped, which is convenient for quickly shoveling and loosening the samples when frying and drying. The arc of the spatula head is adapted to the arc of the frying pan, and the spatula head can slide closely on the surface of the frying pan, better ensuring that the raw meal samples consolidated in the frying pan can be quickly shoveled off; the frying pan has the advantages of small volume and convenient operation.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0006] In the first aspect, a tool for preparing raw meal samples in the sintering process includes:

[0007] A frying pan, the inner and outer surfaces of the frying pan are both arc-shaped, and the edge of the frying pan is connected to a first handle; the outer diameter of the frying pan is 8-12 cm;

[0008] A spatula head, which is made of a trapezoidal plate structure and is arc-shaped. The arc of the spatula head is the same as that of the frying pan to facilitate shoveling off the samples, and one end of the spatula head is connected to a second handle.

[0009] As a further implementation method, heat insulation sleeves are sleeved on the ends of the first handle and the second handle, and connection rings are provided at the ends.

[0010] As a further implementation method, the front end of the first handle is fixed at the bottom of the edge position of the frying pan, the first handle is in a convex arc shape, and the front end of the first handle is tangent to the bottom surface of the frying pan.

[0011] As a further implementation method, the maximum included angle between the tangent of the bottom surface of the frying pan and the horizontal plane does not exceed 20°.

[0012] As a further implementation method, the short side of the shovel head is connected to the second handle, the long side of the shovel head is used for shoveling the sample, and the top surface at the long side of the shovel head is set as an inclined surface structure so that the cross section at the long side position of the shovel head is a sharp angle structure.

[0013] As a further implementation method, it further includes a guiding plate which is bent from a trapezoidal plate so that the guiding plate is arc-shaped, and the guiding plate is used to assist the frying pan to pour the sample into the material bucket.

[0014] As a further implementation method, it further includes a funnel body. A cylinder is connected to the lower opening of the funnel body. The outer diameter of the cylinder is 3.5 - 4 cm and is smaller than the inner diameter of the material bucket. A handle is provided on the outer side of the funnel body.

[0015] As a further implementation method, the length of the first handle is 15 - 18 cm.

[0016] As a further implementation method, the long side of the shovel head is 2 - 3 cm.

[0017] In a second aspect, a method for preparing a sintered raw material sample is characterized in that the tool for preparing a sintered raw material sample as described above is adopted, and it includes the following steps:

[0018] Take a set amount of raw material sample into the frying pan, transfer the frying pan to the electric heating device through the first handle, adjust the temperature of the electric heating device to heat the frying pan. When the raw material sample is nearly dried, use the long side of the shovel head to shovel the raw material sample in the frying pan through the second handle to prevent the raw material sample from sticking to the frying pan. Then crush the raw material sample into blocks, and then continue to crush the blocky raw material sample with the bottom surface of the shovel head; finally, use the funnel or the guiding plate to transfer the raw material sample in the frying pan to the material bucket of the crusher.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The inner and outer surfaces of the frying pan of the present invention are both arc-shaped, which is convenient for quickly shoveling and loosening the sample when frying. Both the frying pan and the shovel head are equipped with handles, and the curvature of the shovel head is adapted to the curvature of the frying pan. The shovel head can slide closely on the surface of the frying pan, maximizing the elimination of the gap when the bottom surface of the shovel head contacts the top surface of the frying pan, and better ensuring that the raw material sample consolidated in the frying pan can be quickly shoveled off; the outer diameter of the frying pan is 8 - 12 cm, which has the advantages of small volume and convenient operation.

[0021] 2. The maximum angle between the tangent line of the bottom surface of the stir-frying pan of the present invention and the horizontal plane does not exceed 20°. The purpose is to ensure that the raw material sample in the stir-frying pan is heated to the maximum extent and prevent the uneven heating of the sample caused by the large curvature of the stir-frying pan. This design can improve the heating efficiency.

[0022] 3. The shovel head of the present invention is made of a trapezoidal plate structure. Using the long side to scoop the sample can increase the contact area between the shovel head and the sample, improving work efficiency. At the same time, it can also ensure that when the raw material sample is almost dry, the clumped sample is shoveled off the stir-frying pan first before being crushed. If a short side shovel is used, the clumped sample will easily be broken first, making it difficult to shovel the clumped sample off the stir-frying pan first, greatly reducing work efficiency.

[0023] 4. The present invention utilizes a transfer tool to quickly transfer the sample in the stir-frying pan to the material barrel. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] It should be noted that the following detailed description is illustrative and aims to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0035] Embodiment 1

[0036] In a typical implementation of the present invention, referring to Figure 1 as shown, a sintering method raw material sample preparation tool includes a stir-frying pan 1, a shovel head 4 and a feeding structure.

[0037] As Figure 1 and Figure 2 shown, both the inner and outer surfaces of the stir-frying pan 1 are arc-shaped, which is formed by pressing a circular plate, with the same curvature everywhere, and the top edge is polished smoothly.

[0038] The edge of the stir-frying pan 1 is connected to the first handle 2 for convenient operation. The end of the first handle 2 is sleeved with a heat insulation sleeve 3, and the position of the heat insulation sleeve 3 serves as the holding part, playing a role in heat insulation.

[0039] As Figure 3 and Figure 4 shown, the shovel head 4 is used to loosen the solidified raw material sample in the stir-frying pan. The shovel head 4 is made of a trapezoidal plate structure and pressed into an arc-shaped plate structure.

[0040] When the sample in the stir-frying pan 1 is heated on the electric heating device 6, the flowing raw material sample is heated and dried, and it is easy to form a mass and stick to the stir-frying pan 1. One end of the shovel head 4 is connected to the second handle 5, which is convenient to hold the second handle 5. The raw material sample mass sticking to the stir-frying pan 1 can be shoveled off by the shovel head, and the raw material sample can also be shoveled into pieces. The raw material sample shoveled into pieces can be further crushed by the shovel head 4 to facilitate subsequent grinding work.

[0041] As Figure 1 and Figure 3 shown, heat insulation sleeves 3 are sleeved on the ends of both the first handle 2 and the second handle 5, and a connecting ring 21 is provided at the rear end of the handle. The setting of the heat insulation sleeve 3 can play a role in heat insulation and prevent the heated handle from scalding the hand.

[0042] As Figure 2 shown, the setting of the connecting ring 21 facilitates hanging the tool on a hook when the tool is not in use, which is convenient for storage.

[0043] The outer diameter of the frying pan 1 in this embodiment is 8 - 12 cm, preferably 10 cm, which is of appropriate size, small in mass, and convenient to operate without burden.

[0044] As Figure 4 shown, in order to enable the shovel head 4 to better shovel the raw material sample in the frying pan 1, the arc of the shovel head is consistent with the arc of the frying pan 1, and the shovel head 4 can slide closely on the surface of the frying pan 1, maximizing the elimination of the gap when the bottom surface of the shovel head 4 contacts the top surface of the frying pan 1, and better ensuring that the raw material sample consolidated in the frying pan 1 can be quickly shoveled off.

[0045] It can be understood that when the frying pan 1 containing the raw material sample is placed on the electric heating device for heating, as the sample gradually dries, it is necessary to increase the frying frequency and intensity of the shovel head 4 to ensure that the sample is evenly heated as a whole, and at the same time observe the change of the sample particles to prevent the sample from sticking or local sintering until the sample is nearly dried and the surface is in a loose state.

[0046] As Figure 2 shown, the front end of the first handle 2 is welded and fixed at the bottom of the edge position of the frying pan 1. The first handle 2 is arranged in the shape of a convex arc plate, and the front end of the first handle 2 is tangent to the bottom surface of the frying pan 1. The arc-shaped setting of the first handle can enable the staff to exert force better and is convenient for operation.

[0047] It can be understood that the maximum included angle between the tangent line of the bottom surface of the frying pan 1 in this example and the horizontal plane does not exceed 20°. The purpose is to maximize the heating of the raw material sample in the frying pan 1 and prevent the situation of uneven heating of the sample caused by too large an arc of the frying pan 1. This design can improve the heating efficiency.

[0048] As Figure 3 and Figure 4 shown, since the shovel head 4 is formed by bending a trapezoidal plate structure, the short side of the shovel head 4 is connected to the second handle, and the long side of the shovel head 4 is used to shovel the sample. Using the long side to shovel the sample can increase the contact area between the shovel head 4 and the sample and improve work efficiency; at the same time, it can also ensure that when the raw material sample is nearly dried, the agglomerated sample is first shoveled off from the frying pan 1, and then the crushing work is carried out. If the short side is used to shovel the sample, it is easy to cause the agglomerated sample to be shoveled off first, which is not convenient for the agglomerated sample to be shoveled off from the frying pan 1 first, greatly reducing the work efficiency.

[0049] In order to better shovel the sample, as Figure 4 shown, the top surface at the long side of the shovel head 4 is set as an inclined surface structure, so that the cross-section at one end of the long side of the shovel head 4 is a sharp angle structure. When shoveling the sample, the agglomerated sample can be better shoveled off.

[0050] In a preferred example, after the trapezoidal plate is bent into the shovel head 4 , the upper surface of one end of the long side of the shovel head 4 is polished so that the thickness of the end of the long side of the shovel head 4 is smaller, forming a tip 41 .

[0051] For transferring the sample crushed by the shovel head 4, a transfer tool is needed to transfer the sample into a material bucket, and then the material bucket is placed in a grinder for grinding.

[0052] like Figure 5 and Figure 6 As shown, the transfer tool includes a guide plate 7, which is formed by bending a trapezoidal plate so that the guide plate 7 is arc-shaped. Figure 5 As shown, the upper end of the guide plate 7 can be concave and polished to form an arc-shaped edge 8, which is better close to the edge of the bottom surface of the frying plate 1. The lower end of the guide plate 7 is the discharge port 9, and its width is smaller than the inner diameter of the barrel. When transferring the sample, the upper end of the guide plate 7 abuts the edge of the bottom surface of the frying plate 1, and the lower end abuts the inner side of the top of the barrel. Slowly rotate the frying plate 1 and the guide plate to tilt them, and then pour the loose sample into the barrel.

[0053] Alternatively, a funnel structure can be used, such as Figure 7 As shown, the funnel body 11 includes a funnel body 11, the lower opening of which is connected to a cylinder 12. The outer diameter of the cylinder 12 is 3.5-4 cm, which is smaller than the inner diameter of the bucket. The outer side of the funnel body is provided with a handle 13 for easy operation. The diameter of the top opening of the funnel body 11 is 14-15 cm, which is larger than the diameter of the stir-fry pan 1.

[0054] The opening size of the top end of the funnel body 11 is larger than the outer diameter of the stir-frying pan 1 , and the funnel body can also be used to assist in transferring the raw material sample in the stir-frying pan.

[0055] It can be understood that the long side of the shovel head is 2-3 cm, preferably 3 cm.

[0056] It is understood that the stir-frying pan 1 has a thickness of 0.1 cm, a handle thickness of 0.15 cm, and a length of 23-28 cm, preferably 25 cm. All preparation tools can be made of stainless steel plates, which do not chemically react with the elements CaO, Na2O, Al2O3, SiO2, Fe2O3, TiO2, MgO, and K2O in the material at 250°C.

[0057] Embodiment 2

[0058] In a typical embodiment of the present invention, referring to Figures 1-7 As shown, a method for preparing a raw material sample by sintering method is characterized by using the raw material sample preparation tool by sintering method described in Example 1, comprising the following steps:

[0059] Use a sampling spoon to take a set amount (15 g) of raw material sample into the frying pan 1, and transfer the frying pan 1 to the electric heating device 6 through the first handle 2. The electric heating device 6 is a prior art. Adjust the temperature of the electric heating device 6 to heat the frying pan to achieve heating of the sample. During the frying process, use the second handle to gently turn the sample with the shovel head.

[0060] When the raw material sample is nearly dried, use the second handle 5 to shovel the raw material mass sample in the frying pan 1 with the long side of the shovel head 4 to prevent the raw material mass sample from sticking to the frying pan 1. Then, crush the raw material sample into lumps, and further crush the lumpy raw material sample with the bottom surface of the shovel head 4. Finally, use a funnel or a guiding plate 7 to transfer the raw material sample in the frying pan 1 to the hopper of the crusher.

[0061] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
