Description

A sodium bromide feeding and screening device Technical Field

[0001] This utility model relates to the field of sodium bromide screening technology, and in particular to a sodium bromide feeding and screening device. Background Technology

[0002] Sodium bromide is an inorganic compound composed of sodium and bromine. It is a white crystalline or granular substance, commonly soluble in water, and the solution is neutral. In the urea recovery process, soda ash (sodium carbonate) and urea are dissolved in hot water and fed into a reverberatory furnace to slowly react with bromine to produce sodium bromide. The sodium bromide product is then obtained through processes such as activated carbon decolorization, filtration, evaporation crystallization, centrifugation, and drying.

[0003] Dried sodium bromide often has defects such as varying particle sizes and excessive impurities, requiring screening to meet requirements. Existing screening devices use screens with fixed positions and apertures. Due to the fixed aperture size, graded screening cannot be achieved, resulting in low screening efficiency and incomplete screening. Furthermore, the screens are prone to clogging, and if not cleaned promptly, this further reduces screening efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a sodium bromide feeding and screening device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sodium bromide feeding and screening device includes a screening box, with an inlet and an outlet respectively provided at the top and bottom of the screening box. A rotating shaft is rotatably arranged inside the screening box, and a motor for driving the rotating shaft is installed on the top of the screening box. Several screening plates are fixedly connected to the rotating shaft, arranged at intervals from top to bottom and located inside the screening box.

[0007] Several metal rods are installed at the top edge of the screening plate, and an elastic striking component that cooperates with the metal rods is fixedly connected to the inner wall of the screening box. The rotation of the screening plate drives the metal rods to reciprocate and intermittently contact the elastic striking component, thereby achieving slight vibration of the screening plate.

[0008] Two rotating rods perpendicular to the rotating shaft are rotatably mounted on it. A cutting roller and a brush roller are respectively fixedly sleeved on the two rotating rods, and the cutting roller and the brush roller respectively contact the surface of the screening plate.

[0009] Preferably, the aperture of the plurality of screening plates is arranged from large to small from top to bottom.

[0010] Preferably, the elastic striking assembly includes a box body fixedly connected to the inner wall of the screening box, a pivot pin fixedly connected inside the box body, a striking rod hinged to the pivot pin, a horizontal shaft fixedly connected inside the box body, a slider slidably disposed on the horizontal shaft, a spring sleeved on the horizontal shaft, the two ends of the spring respectively abutting against the slider and the box body, and a connecting rod hinged between the slider and the striking rod.

[0011] Preferably, every two metal rods form a group, and the metal rods in each group are in contact with the striking rod at intervals.

[0012] Preferably, the rotating shaft is hollow and has a receiving section thereon, the screening plate is fixedly connected to the bottom of the receiving section, the rotating rod is rotatably mounted on the receiving section, and the opposite ends of the two rotating rods respectively pass through the receiving section and are fixedly connected to rotating bevel gears.

[0013] Preferably, a support rod is fixedly connected to the top of the screening box, and the end of the support rod away from the screening box passes through and extends into the rotating shaft. The support rod and the rotating shaft are connected by a sealed bearing, and a fixed bevel gear located in the receiving section and meshing with the rotating bevel gear is fixedly sleeved on the support rod.

[0014] Preferably, the surface of the screening box is provided with cleaning through holes that match the screening plate, and a sealing plate that can close the cleaning through holes is hinged to the screening box.

[0015] Preferably, a sprocket is fixedly sleeved between the output end of the motor and the top end of the rotating shaft, and a chain is provided between the two sprockets for transmission.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this application, by using a rotatable screening plate with apertures arranged from large to small from top to bottom, sodium bromide particles pass through screening plates of different apertures sequentially under the action of gravity and rotational force, achieving graded screening. At the same time, the cooperation between the metal rod at the top of the screening plate and the elastic striking component causes the screening plate to vibrate slightly during rotation, which helps the particles pass through the screen holes better and prevents the particles from clogging the screen holes, further optimizing the screening effect and greatly improving the screening efficiency.

[0018] 2. In this application, while the rotating shaft rotates, the rotating rod moves along with it and rotates by the cooperation of the rotating bevel gear and the fixed bevel gear, thereby driving the cutting roller and the brush roller to rotate. The cutting roller can cut the sodium bromide particles, reduce the particle size, and facilitate subsequent screening. At the same time, the brush roller can clean the surface of the screening plate, prevent the screen holes from clogging, and ensure that the screening is carried out continuously and stably.

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] As shown in Figures 1-7, this utility model provides a sodium bromide feeding and screening device, including a screening box 100. The top and bottom of the screening box 100 are respectively provided with a feed inlet and a discharge outlet. A rotating shaft 200 is rotatably arranged inside the screening box 100. A motor 300 for driving the rotating shaft 200 to rotate is installed on the top of the screening box 100. Several screening plates 400 are fixedly connected to the rotating shaft 200 and are arranged at intervals from top to bottom and located inside the screening box 100.

[0030] Several metal rods 500 are installed at the top edge of the screening plate 400. An elastic striking component 600 that cooperates with the metal rods 500 is fixedly connected to the inner wall of the screening box 100. The rotation of the screening plate 400 drives the metal rods 500 to reciprocate and intermittently contact the elastic striking component 600, thereby achieving slight vibration of the screening plate 400.

[0031] Two rotating rods 700 perpendicular to the rotating shaft 200 are rotatably mounted on the shaft. A cutting roller 800 and a brush roller 900 are respectively fixedly sleeved on the two rotating rods 700. The cutting roller 800 and the brush roller 900 respectively contact the surface of the screening plate 400.

[0032] In this embodiment, the apertures of several screening plates 400 are arranged from large to small from top to bottom to achieve graded screening.

[0033] In this embodiment, the elastic striking component 600 includes a box 601 fixedly connected to the inner wall of the screening box 100. A shaft pin 602 is fixedly connected inside the box 601. A striking rod 603 is hinged to the shaft pin 602. A horizontal shaft 604 is fixedly connected inside the box 601. A slider 605 is slidably disposed on the horizontal shaft 604. A spring 606 is sleeved on the horizontal shaft 604. The two ends of the spring 606 abut against the slider 605 and the box 601, respectively. A connecting rod 607 is hinged between the slider 605 and the striking rod 603. A metal rod 500 contacts the striking rod 603 and causes it to deflect. The striking rod 603 pushes the slider 605 to slide along the horizontal shaft and compress the spring 606 through the connecting rod 607.

[0034] In this embodiment, every two metal rods 500 form a group, and each group of metal rods 500 contacts the striking rod 603 at intervals.

[0035] In this embodiment, the rotating shaft 200 is hollow and has a receiving section 201 on it. The screening plate 400 is fixedly connected to the lower part of the receiving section 201. The rotating rods 700 are rotatably mounted on the receiving section 201. The opposite ends of the two rotating rods 700 respectively penetrate into the receiving section 201 and are fixedly connected to a rotating bevel gear 202. The top of the screening box 100 is fixedly connected to a support rod 203. The end of the support rod 203 away from the screening box 100 penetrates and extends into the rotating shaft 200. The support rod 203 and the rotating shaft 200 are connected by a sealed bearing. A gear located in the receiving section 201 is fixedly sleeved on the support rod 203. The fixed bevel gear 204 meshes with the rotating bevel gear 202. When the rotating shaft 200 rotates, it drives the rotating rod 700 to move circumferentially. During this process, the rotating bevel gear 202 remains meshed with the fixed bevel gear 204. The rotating bevel gear 202 rotates under the action of the fixed bevel gear 204, which in turn drives the rotating rod 700 to rotate the cutting roller 800 and the brush roller 900. The rotation of the cutting roller 800 has a cutting effect on the sodium bromide particles, which reduces the size of the sodium bromide particles and facilitates subsequent processing. The rotating brush roller 900 can clean the screening plate 400 and prevent the screening plate 400 from clogging during the screening process.

[0036] In this embodiment, the surface of the screening box 100 is provided with a cleaning through hole 101 that matches the screening plate 400. A sealing plate 102 that can close the cleaning through hole 101 is hinged on the screening box 100. The sealing plate 102 is closed during screening and can be opened after screening to clean the screening plate through the cleaning through hole 101.

[0037] In this embodiment, sprockets 301 are fixedly sleeved between the output end of the motor 300 and the top end of the rotating shaft 200, respectively. A chain 302 is provided between the two sprockets 301 for transmission. The motor 300 drives the sprockets 301 to rotate, and the transmission of the chain 302 causes the other sprocket 301 to drive the rotating shaft 200 to rotate.

[0038] How to use and how to work this device:

[0039] When the device is in use, sodium bromide particles are first fed into the screening box 100 through the feed port at the top of the screening box 100. The motor 300 drives the rotating shaft 200 to rotate through the sprocket 301 and the chain 302. The rotating shaft 200 drives the screening plate 400 to rotate. The screening plate 400 is set with the aperture from large to small from top to bottom. Under the action of gravity and rotational force, the sodium bromide particles pass through the screening plates 400 with different apertures in sequence to achieve grading and screening.

[0040] When the rotating shaft 200 rotates, it can drive the rotating rod 700 to move circumferentially. Through the cooperation of the rotating bevel gear 202 and the fixed bevel gear 204, the rotating rod 700 is driven to rotate. The cutting roller 800 and the brush roller 900 on the rotating rod 700 rotate accordingly. The cutting roller 800 cuts the sodium bromide particles to reduce the particle size, which facilitates subsequent screening and improves the screening effect and efficiency. The brush roller 900 can clean the surface of the screening plate 400 to prevent the screen holes from clogging and ensure that the screening is continuous and stable.

[0041] Meanwhile, the metal rods 500 on the top of the screening plate 400 rotate with the screening plate 400. Every two metal rods 500 form a group. The metal rod 500 in front first contacts the striking rod 603 and pushes the striking rod 603. The striking rod 603 pushes the slider 605 along the crossbar through the connecting rod 607 and squeezes the spring 606. As the rotation continues, the metal rod 500 and the striking rod 603 separate. Under the action of the spring 606, the slider 605 is pushed, which drives the connecting rod 607 to reset the striking rod 603. The striking rod 603 can then strike the next metal rod 500, causing the screening plate 400 to vibrate slightly, which can better perform screening and prevent particles from clogging the screen holes.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
