Description

Technical Field

[0001] The utility model relates to the technical field of sodium ion battery production, in particular to a device for screening out large-particle impurities at a feed outlet. Background Art

[0002] Sodium-ion batteries (SIBs) are a new type of high-energy-density battery. Unlike the graphite anode material used in lithium-ion batteries, conventional graphite is considered incompatible with SIBs due to the small interlayer spacing between graphite layers. Therefore, sodium ions with larger radii require greater energy to intercalate between the graphite layers, preventing reversible intercalation and deintercalation within the effective potential window. Research on SIB anode materials includes hard carbon, soft carbon, titanium-based oxides, and alloys, with hard carbon being the most studied. Currently, commercial SIBs primarily use hard carbon as their anode material.

[0003] In actual production, the equipment uses agricultural and forestry waste rich in lignin, cellulose, and hemicellulose (such as straw, sawdust, rice husks, fruit shells, coconut shells, palm shells, tree branches and bark, logs, firewood, and palm fiber) as raw materials. Through dry distillation and pyrolysis, the carbon and hydrogen elements in the raw materials are converted into a mixed combustible gas with high calorific value, such as hydrogen, methane, ethane, and carbon monoxide. Simultaneously, charcoal and byproducts such as wood vinegar and tar are produced. The sintering process produces a large number of large impurity particles and tar lumps, which seriously affect subsequent processing. Therefore, measures must be taken to remove these large particles at the discharge end. Utility Model Content

[0004] In order to solve the above problems, the utility model aims to propose a device for screening out large particles of impurities at the discharge port. The discharge speed is slowed down and the material is coarsely screened through a large-mesh screen (to prevent extra-large particles from affecting the outflow of impurities on the inclined screen). The large particles of impurities generated in the sintered material can be screened out and collected as a whole through an external collection bucket. The additional screening process of the sintered material can be eliminated, and the large particles of impurities in the material can be removed simply and efficiently. The charcoal and by-products wood vinegar and tar are screened out through the inclined screen, solving the problem of machine jamming encountered in the next process section.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A device for screening out large particles of impurities at a discharge port, comprising a connecting pipe, wherein a movable flange for connecting to the discharge port of the equipment is provided at the upper end of the connecting pipe, a large-mesh screen is provided at the upper end of the connecting pipe, and an inclined screen is provided at the lower end. The bottom of the inclined screen corresponds to a stainless steel pipe on the side of the connecting pipe, and a discharge pipe is connected below the inclined screen. The stainless steel pipe is connected to an external collection bucket through a hose.

[0007] Furthermore, the large mesh sieve has a pore size of 2 cm, and the oblique sieve has a pore size of 1 cm.

[0008] Furthermore, the stainless steel tube is set at an angle of 45 degrees.

[0009] Furthermore, an observation port is provided on the side between the connecting pipe and the discharge pipe.

[0010] Furthermore, the inner side of the observation port is provided with upper and lower stepped iron wires and a track for inserting the screen.

[0011] Beneficial effects: The utility model slows down the material feeding speed and performs coarse screening of the material through a large-mesh screen (to prevent extra-large particles from affecting the outflow of impurities on the inclined screen). The large-particle impurities generated in the sintered material can be screened out and collected as a whole through an external collection bucket, which can save the additional screening process of the sintered material, simply and efficiently remove the large-particle impurities in the material, and screen out the charcoal and by-products wood vinegar and tar through the inclined screen, thereby solving the problem of machine jamming encountered in the next process section.

[0015] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] Example 1

[0017] See also Figure 1-2 : A device for screening out large particles of impurities at a discharge port, comprising a connecting pipe 1, a movable flange 101 for connecting to the discharge port of the equipment is provided at the upper end of the connecting pipe 1, a large-mesh screen 2 is provided at the upper end of the connecting pipe 1, and an inclined screen 3 is provided at the lower end. The bottom of the inclined screen 3 corresponds to a stainless steel pipe 4 on the side of the connecting pipe 1, and a discharge pipe 5 is connected below the inclined screen 3. The stainless steel pipe 4 is connected to an external collection bucket through a hose 6.

[0018] In this embodiment, the material feeding speed is slowed down and the material is coarsely screened by a large-mesh screen (to prevent oversized particles from affecting the outflow of impurities on the inclined screen). The large-particle impurities generated in the sintered material can be screened out and collected as a whole through an external collection bucket, which can save the additional screening process of the sintered material, simply and efficiently remove the large-particle impurities in the material, and screen out the charcoal and by-products wood vinegar and tar through the inclined screen, thereby solving the problem of machine jamming encountered in the next process section.

[0019] In a specific example, the large mesh sieve 2 has a pore size of 2 cm, and the oblique sieve has a pore size of 1 cm.

[0020] In practical applications, large mesh screens and inclined screens can be selected with different mesh sizes according to needs.

[0021] In a specific example, the stainless steel tube 4 is arranged at an angle of 45 degrees.

[0022] In this embodiment, the angle between the stainless steel pipe and the discharge pipe is set to 45°.

[0023] In a specific example, an observation port 7 is further provided on the side between the connecting pipe 1 and the discharge pipe 5 .

[0024] In this embodiment, the discharge effect of the sieved particles can be observed through the observation port, and the large-mesh screen can be replaced and cleaned in time; in actual use, the actual screening effect can be observed through the observation port. If small particles are intercepted, the size of the screen holes can be appropriately increased; after the screening material is observed, if larger particles still exist, the size of the drying mesh can be reduced to effectively intercept them.

[0025] In a specific example, the inner side of the observation port 7 is provided with upper and lower stepped iron wires and a track 701 for inserting a screen.

[0026] In this embodiment, the slope of the screen can be adjusted by inserting the screen track in an up and down step-by-step manner. After the right side is opened, the pipeline is non-standardly modified into a rectangular opening, and iron wire and the screen track are welded from top to bottom at the opening. The slope of the inclined screen can be changed by inserting different tracks to enhance the screening effect according to the particles of the material being fed.

[0027] In summary, in this embodiment, after sintering, the material or particles fall into the discharge pipe through the flange. When passing through the large-mesh screen (assuming the screen opening is 2 cm), the material larger than the screen opening is screened out, preventing oversized particles from affecting the screening effect of the inclined screen and preventing the inclined screen from clogging. The majority of the remaining material is screened by the inclined screen, and large particles of impurities flow out of the discharge pipe to the hose and into the prepared collection bucket. The observation port is used to observe the status of the material on the large-mesh screen. The large-mesh screen is cleaned once every 1 ton of production.

[0028] In actual use, the actual screening effect can be observed through the observation port. If small particles are intercepted, the size of the screen holes can be appropriately increased. After the screening material is observed, if there are still larger particles, the size of the screen holes can be reduced to effectively intercept them.

[0029] In actual use, the observation port is used to observe whether the large particles screened out can be discharged smoothly along the pipeline. By pulling out the inclined screen, inserting different screen wire tracks, and changing the slope of the screen, it is ensured that the large particles screened out can flow out to the hose.

[0030] The material discharge method is direct discharge through the discharge pipe. After the transformation using this technology, useless large particles of impurities can be effectively screened out, and the expected impurity removal effect can be achieved without adding additional screening devices. It is low-cost, simple, easy to transform, and has a wide range of applications.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
