Description

Technical Field

[0001] This utility model relates to the field of potassium fluoroborate preparation technology, specifically to a grading and screening device for potassium fluoroborate preparation waste residue. Background Technology

[0002] During the preparation of potassium fluoroborate, incomplete reaction, incomplete product separation, or impurities introduced by raw materials / processes can lead to the generation of waste residue. This waste residue can be reused after screening, thus achieving recycling.

[0003] During screening, a vibrating screen is used. To achieve fine screening, multiple screen frames and screens are usually stacked to enable grading. Waste residue is usually poured directly onto the screen for screening. However, because the waste residue is damp and easily clumps together and sticks to the screen, it needs to be cleaned regularly, which is quite troublesome. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem this invention aims to solve is that wet waste residue is prone to clumping and sticking to the screening screen, requiring regular cleaning, which is quite troublesome.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a grading and screening device for potassium fluoroborate preparation waste residue, including a vibrating screen, a support on the vibrating screen, a sleeve on the support that cooperates with the vibrating screen, a shell on the sleeve, a conveyor belt inside the shell, a smoothing mechanism inside the shell for smoothing the waste residue on the conveyor belt, an insertion hole on one side of the smoothing mechanism inside the shell, an insert plate movably inserted into the insertion hole, an extension rod on the bottom surface of the insert plate, a drying plate on the extension rod for drying the waste residue on the surface of the conveyor belt, and a crushing mechanism for breaking up clumps inside the shell on one side of the drying plate.

[0008] As an improvement, the smoothing mechanism includes two limiting plates inside the housing to limit the conveyor belt, and the limiting plates are provided with inclined plates to scrape the waste residue.

[0009] As an improvement, the crushing mechanism includes a rotating shaft rotatably disposed within a housing, a flattening roller mounted on the rotating shaft, and a motor for driving the rotating shaft to rotate on the housing.

[0010] As an improvement, the rotation direction of the rotating shaft is opposite to the rotation direction of the conveyor belt shaft.

[0011] As an improvement, the conveyor belt is equipped with a scraper for scraping off waste residue from the surface of the conveyor belt.

[0012] As an improvement, a connecting sleeve is provided between the sleeve and the vibrating screen. The connecting sleeve is deformable and can adapt to the vibration of the vibrating screen.

[0013] As an improvement, the insert plate is fixedly connected to the housing by bolts.

[0014] (III) Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] A conveyor belt is used to transport the waste residue. A leveling mechanism is used to evenly spread the waste residue on the conveyor belt. Insert plates, extension rods, and drying plates are used to dry the waste residue to prevent it from sticking to the filter screen and causing blockage during subsequent screening. A crushing mechanism is used to disperse the dried and agglomerated waste residue for easy screening. A sleeve and connecting sleeve are used to allow the dried waste residue to enter the screening screen from the sleeve. Since the waste residue is somewhat hazardous and inhalation is harmful to health, a connecting sleeve is used to prevent powder from overflowing from the gap between the sleeve and the screening screen.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As per the instructions Figures 1 to 4 As shown, a grading and screening device for potassium fluoroborate preparation waste residue includes a vibrating screen 1, a support 2 on the vibrating screen 1, a sleeve 3 on the support 2 that cooperates with the vibrating screen 1, a housing 4 on the sleeve 3, a conveyor belt 5 inside the housing 4, a smoothing mechanism 6 inside the housing 4 for smoothing the waste residue on the conveyor belt 5, an insertion hole 7 on one side of the smoothing mechanism 6 inside the housing 4, an insert plate 8 movably inserted into the insertion hole 7, the insert plate 8 being fixedly connected to the housing 4 by bolts, an extension rod 9 on the bottom surface of the insert plate 8, a drying plate 10 on the extension rod 9 for drying the waste residue on the surface of the conveyor belt 5, and a crushing mechanism 11 for breaking up clumps inside the housing 4 on one side of the drying plate 10.

[0026] First, the waste residue is poured onto conveyor belt 5, ensuring it is evenly distributed. Conveyor belt 5 then transports the waste residue, while leveling mechanism 6 pushes excess residue to the sides, maintaining the thickness of the residue on conveyor belt 5 to ensure effective drying and prevent the bottom residue from remaining uncooked due to excessive thickness. The residue then passes through drying plate 10 (existing technology, details omitted here), which dries the waste residue. After drying, crushing mechanism 11 breaks up any clumps of powder, facilitating subsequent sieving. The crushed waste residue powder then falls from the end of conveyor belt 5 into sleeve 3, and then onto vibrating screen 1. Vibrating screen 1 performs grading and sieving of the waste residue powder (existing technology, details omitted here). This grading and sieving process yields waste residue of different mesh sizes for later use.

[0027] As per the instructions Figures 2 to 6 As shown, the smoothing mechanism 6 includes two limiting plates 12 inside the housing 4 that limit the conveyor belt 5. The limiting plates 12 are provided with inclined plates 13 for smoothing the waste residue. When the conveyor belt 5 transports the waste residue past the limiting plates 12, the excess powder will be blocked by the inclined plates 13, thus keeping the excess powder at the limiting plates 12. When there is less powder on the subsequent conveyor belt 5, the excess powder will fill in to ensure the thickness of the waste residue powder, which is convenient for subsequent drying. The setting of the limiting plates 12 can prevent the powder from falling off the conveyor belt 5.

[0028] The crushing mechanism 11 includes a rotating shaft 14 rotatably disposed inside the housing 4, a flattening roller 15 mounted on the rotating shaft 14, and a motor 16 mounted on the housing 4 to drive the rotating shaft 14 to rotate. The rotation direction of the rotating shaft 14 is opposite to the rotation direction of the conveyor belt 5. The flattening roller 15 is a certain distance away from the surface of the conveyor belt 5. The motor 16 drives the flattening roller 15 to rotate. Since the rotation direction of the rotating shaft 14 is opposite to the rotation direction of the conveyor belt 5, the flattening roller 15 cooperates with the conveyor belt 5 to squeeze the waste residue powder on the conveyor belt 5, thereby crushing some lumps.

[0029] The conveyor belt 5 is equipped with a scraper 17 for scraping off the waste residue on the surface of the conveyor belt 5. In order to prevent powder from staying on the conveyor belt 5, the scraper 17 is set on the conveyor belt 5 to scrape off the powder staying on the conveyor belt 5 and make it fall into the sleeve 3.

[0030] A connecting sleeve 18 is provided between the sleeve 3 and the vibrating screen 1. The connecting sleeve 18 is deformable and can adapt to the vibration of the vibrating screen 1. By setting the connecting sleeve 18, the scattering of waste residue powder can be prevented. By setting the deformable connecting sleeve 18, it can adapt to the vibration of the vibrating screen 1.

[0031] In practical use, the waste residue is poured onto the conveyor belt 5, and then the conveyor belt 5 is started. The conveyor belt 5 moves the waste residue and then passes through the leveling mechanism 6. The leveling mechanism 6 adjusts the waste residue to maintain its thickness within a certain range to facilitate subsequent drying. Then, the adjusted waste residue passes through the drying plate 10, which dries the waste residue to ensure that there is no moisture in it. After drying, the waste residue passes through the crushing mechanism 11, which disperses the agglomerated waste residue. Then, it enters the sleeve 3 and falls onto the vibrating screen 1. The vibrating screen 1 classifies and screens the waste residue. After screening, the waste residue flows out from each discharge port and is collected by a collection tool, completing the classification and screening process.
