Description

Technical Field

[0001] The utility model relates to the technical field of powder preparation equipment, in particular to a powder distribution device. Background Art

[0002] Powder materials can be divided into inorganic powder and organic powder. Inorganic powder includes talc, mica, silicon dioxide, calcium carbonate, barium sulfate, magnesium hydroxide, zinc oxide, feldspar powder, glass powder, silicon powder, nano calcium carbonate, nano zinc oxide, nano silicon dioxide, etc. Organic powder includes nylon powder, PMMA (polymethyl methacrylate), etc.

[0003] Powder materials can also be divided into high-performance ceramic materials, nanomaterials, biomass powder materials and metal-based composite materials. These materials have specific physical and chemical properties and are suitable for aerospace, automobile manufacturing, electronics, medical treatment, environmental protection and energy.

[0004] The production of powder materials goes through the main processes of polymerization, precipitation, washing, filtration, drying, etc. The moisture content of the powder materials after washing and filtration is as high as over 50%, and the viscosity is extremely high, so the requirements for the distribution device used in the production process are relatively high.

[0005] Chinese patent CN205351944U discloses a drying device for high-moisture content powder biomass, which includes a drying tower, a conical tube and a sand cleaning chamber, as well as a feeding mechanism, a discharging mechanism and a high-temperature air duct arranged in sequence from top to bottom. The feeding mechanism includes a wet material bin and a screw feeder, the wet material bin is connected to the screw feeder, and the screw feeder is installed on the feed port at a downward tilt; this method is continuous feeding during material distribution. Due to the uneven distribution of powder slurry, the material distribution is uneven during the flow drying process, resulting in excessive heat in the part where the material thickness is insufficient when high-temperature heating drying is set, causing the material to deteriorate. At the same time, in the area where the material thickness is excessively concentrated, the material moisture content is high and the drying effect is poor. This is likely to lead to material loss and rework. The energy consumption is large and the product quality is poor.

[0006] In view of the above problems, the utility model provides a device for spreading powder materials with high moisture content. Utility Model Content

[0007] The technical problem solved by the utility model is that in the traditional powder material processing process, the feeding method of high-moisture content powder material has problems such as uneven distribution and inability to control the amount of distribution per unit time. These problems will affect the subsequent processing procedures of the powder material, thereby affecting the production efficiency of the whole process.

[0008] The utility model aims to provide a device for spreading powder materials with high moisture content, which can spread the materials evenly from the outlet of the spreading device to the conveying device according to a certain thickness through the linkage between the bottom valve of the silo and the conveying speed of the conveyor belt, and through a combination of feeding port vibration, partition pre-distribution, conveyor belt vibration and the like, so as to achieve uniform conveying of the materials and ensure the process quality.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A device for spreading powder materials with a high moisture content comprises a silo (1), a vibrator (3) is arranged at the bottom of the silo, the vibrator (3) is connected to a motor (4), a partition (2) is arranged at the connection of the silo, the partition can rotate horizontally, and the end of the silo is connected to a conveying device to output materials.

[0011] Preferably, the partitions are arranged in a number, preferably 3-10, and the partitions can be rotated horizontally and can be set according to parameters such as material flow and viscosity. The angle of the partition (2) can be fixed or can be rotated periodically for adjustment.

[0012] Preferably, the conveying device is composed of a wheel drum (6), a motor (4) and a conveyor belt (7); and the conveyor belt is made of an alloy material.

[0013] Preferably, the number of vibrators (3) below the silo is 1-4, and the number of vibrators (3) below the conveyor belt is 1-4. The vibrators (3) can be set with different vibration frequencies and intensities to meet the fluidity requirements and paving uniformity of the powder slurry.

[0014] Preferably, the outlet of the silo (1) is an angled outlet and is provided with a bottom valve (9). The bottom valve (9) is an automatic ball valve or a butterfly valve, and the opening of the bottom valve can be adjusted according to the conveyor belt material speed to control the feeding speed.

[0015] Preferably, the conveyor belt of the conveying device is composed of a plurality of conveyor belts (7), the speed of the conveyor belt (7) is 0.5-5 m / min, and anti-side overflow baffles (8) are arranged on both sides of each conveyor belt.

[0016] Preferably, the transmission device at the end of the material distribution device has a width of 0.5-2m, and the anti-overflow baffle (8) of a single conveyor belt has a height of 2-10cm.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] When the material is discharged from the bottom valve through the adjustable angle partition and enters the conveying device, it can be evenly spread through vibration, thereby improving the conveyor belt filling rate while ensuring a certain belt speed, and further increasing the processing capacity of the conveying device;

[0019] The flat spreading device of the utility model is suitable for powder materials with high moisture content, and solves the problem that in the traditional processing of powder materials with high moisture content, uneven spreading will easily produce differences in spreading thickness, thereby causing differences in the quality of subsequent processing steps and affecting the production quality of the entire process.

[0020] The utility model solves the problem that powder materials with high moisture content cannot be spread continuously and evenly, improves the spreading device, facilitates further material processing, and achieves better technical effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example

[0028] like Figure 1-3As shown, taking silicone resin micropowder as an example, the initial moisture content of silicone resin micropowder material is 30-60wt%. It is transported to the silo through a pipeline, and the material passes through a vibrator to keep the material in a powder state, and then passes through the partition at the connection of the silo and is discharged from the bottom valve. Since the bottom valve opening is small and the width of the conveyor belt is large, it is necessary to periodically adjust the partition angle to adjust the discharge direction, so that the silicone resin micropowder material enters the conveying device and is pre-laid on the conveying steel belt; at the same time, the conveying speed of the silicone resin micropowder material is adjusted by controlling the opening of the bottom valve;

[0029] The silicone resin micro-powder material is then vibrated by a vibrator to achieve uniform spreading of the micro-powder material to a thickness of 4 cm and a loading width of 0.8 m, so that the silicone resin micro-powder material can enter the next process.
