Description
Technical Field
[0001] This utility model relates to the field of slag brick making technology, and in particular to a pretreatment device for solid waste slag brick making raw materials. Background Technology
[0002] With the increasing awareness of environmental protection and the promotion of the concept of resource recycling, the use of solid waste slag to produce building bricks has become an important way to realize the resource utilization of waste. In this process, the slag needs to be pretreated, including crushing, screening, drying and activation.
[0003] Currently, most existing slag pretreatment devices achieve their effects using the following technologies;
[0004] Crushing technologies: Jaw crushers are used for coarse crushing and have a simple structure; cone crushers are suitable for medium and fine crushing and produce uniform products; impact crushers can produce fine and uniform products, but the parts wear out quickly.
[0005] Screening technology: Vibrating screens have high screening efficiency and accuracy, and adjustable parameters, but their components are easily damaged; drum screens are suitable for a variety of materials and are not prone to clogging, but they occupy a large area and have lower accuracy.
[0006] Magnetic separation technology: It uses a magnetic field to adsorb magnetic substances in slag, removing ferromagnetic impurities. It is often used in conjunction with other technologies to improve the purity of slag.
[0007] Mixing technology: Paddle mixers have a simple structure and low cost, but the mixing uniformity is generally poor; ribbon mixers have a good mixing effect and can process large quantities of materials, but they consume a lot of energy and have a large equipment size.
[0008] Drying technology: Rotary kiln drying has a large processing capacity, but the investment and energy consumption are high; airflow drying is fast and efficient, but it has requirements for materials and requires dust removal equipment.
[0009] Currently, existing slag pretreatment devices have been found to have at least the following technical problems in actual use;
[0010] Existing slag pretreatment devices require screening after crushing to recycle larger particles for further crushing. However, the filter screens of existing screening devices are mostly fixedly connected inside the screening chamber, making them difficult to disassemble and clean. Therefore, most existing slag screening devices suffer from clogged filter screens that are difficult to clean. Utility Model Content
[0011] To address the shortcomings of existing technologies, this utility model provides a pretreatment device for solid waste slag brick-making raw materials, solving the problem of difficult-to-clean filter screens in existing slag screening devices.
[0012] To achieve the above objectives, this utility model provides the following technical solution:
[0013] A pretreatment device for raw materials for brick making from solid waste slag includes two support legs and a screening chamber. One support leg is fixedly connected to a PLC controller. A high-strength spring is installed between the support leg and the screening chamber. A screening mechanism for screening slag is slidably connected to the inner side of the screening chamber. The screening chamber is equipped with a limiting mechanism to limit the movement of the screening mechanism. Connecting plates are fixedly connected to both side walls of the screening chamber. Vibration motors are fixedly connected to the top surfaces of both connecting plates. The screening mechanism includes a filter plate with two through holes at one end. The limiting mechanism includes a limiting plate, an inclined groove, a limiting sleeve, and a bolt.
[0014] Preferably, a guide plate is fixedly connected to the inner wall of the screening chamber, a discharge port is fixedly connected to one side of the screening chamber, and a discharge funnel is fixedly connected to the bottom of the screening chamber.
[0015] Preferably, there are two limiting plates, both of which are fixedly connected to the inner wall of the screening chamber.
[0016] Preferably, the inclined chute is located on the side of the screening chamber away from the limiting plate, and there are two limiting sleeves and two bolts, with both limiting sleeves fixedly connected to the screening chamber.
[0017] Preferably, the filter plate is inserted into the inner side of the inclined groove, the filter plate is clamped between two limiting plates, the two plugs are slidably sleeved with the two limiting sleeves respectively, and the two plugs are inserted into the two through holes respectively.
[0018] Preferred configuration: Two support legs are fixedly connected to a back plate, and six high-strength springs are fixedly connected to the top surface of each support leg. Twelve high-strength springs are fixedly connected to two connecting plates respectively. Eight high-strength springs are fixedly connected to the surface of the back plate, and the ends of the eight high-strength springs away from the back plate are fixedly connected to the screening chamber.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. After prolonged use, some slag may adhere to the surface of the filter plate, potentially causing blockage. In this case, the two plugs can be pulled out directly from the limiting sleeve to separate the plugs from the through holes. The filter plate can then be pulled out directly from the inclined groove, making disassembly quick and easy. The filter plate can then be cleaned. In this application, the filter plate can be disassembled simply by pulling out the two plugs. Compared to existing threaded or welded filter plates, this application facilitates disassembly and cleaning, solving the problem of difficult-to-clean filter screens in existing slag screening devices.
[0021] II. In this application, slag solid waste crushed by an impact crusher is received through a screening bin. Part of the slag falling into the screening bin directly contacts the filter plate, while the other part contacts the guide plate and is guided by the guide plate to the end of the filter plate away from the discharge port. During the screening process, two vibration motors are started by a PLC controller. The vibration motors drive the entire screening bin to vibrate through a connecting plate. Due to the setting of high-strength springs, the vibration frequency of the screening bin is increased, causing the slag to jump above the filter plate. Slag that meets the standards falls directly through the filter plate into the discharge funnel, while larger slag particles will continuously jump downwards on the surface of the filter plate and finally be discharged through the discharge port. This application can vibrate while screening, giving it the advantage of being less prone to clogging. Attached Figure Description

[0035] Two support legs 1 are fixedly connected to a back plate 102. Six high-strength springs 3 are fixedly connected to the top surface of each of the two support legs 1. Twelve high-strength springs 3 are fixedly connected to two connecting plates 205 respectively. Eight high-strength springs 3 are fixedly connected to the surface of the back plate 102. The ends of the eight high-strength springs 3 away from the back plate 102 are fixedly connected to the screening chamber 2.
[0036] Support leg 1: Supports screening chamber 2, connects to back plate 102 and high-strength spring 3, and provides stable support for the whole.
[0037] Screening bin 2: Receives slag solid waste crushed by impact crusher. The guide plate 202 inside guides the slag, the discharge port 201 discharges larger slag particles, and the discharge funnel 203 collects slag that meets the standards, playing the main role of screening slag.

[0052] Working principle:
[0053] In the first step, this application receives slag solid waste crushed by an impact crusher through a screening bin 2. Part of the slag falling into the screening bin 2 directly contacts the filter plate 5, and the other part contacts the guide plate 202. The guide plate 202 guides the filter plate 5 away from the discharge port 201. During the screening process, two vibration motors 4 are started by the PLC controller 101. The vibration motors 4 drive the entire screening bin 2 to vibrate through the connecting plate 205. Due to the setting of the high-strength spring 3, the vibration frequency of the screening bin 2 is increased, causing the slag to jump above the filter plate 5. Slag that meets the standard falls directly through the filter plate 5 into the discharge funnel 203. Larger slag particles will continuously jump downward on the surface of the filter plate 5 and finally be discharged through the discharge port 201. Finally, it is introduced into the crusher for crushing again through an external pneumatic conveyor to achieve screening.
[0054] The second step is that after the filter plate 5 has been used for a long time, some slag will stick to the surface, which may cause blockage. At this time, the two plugs 208 can be pulled out directly from the limiting sleeve 207 to separate the plugs 208 from the through hole 501. Then the filter plate 5 can be pulled out directly from the inclined groove 206 to disassemble the filter plate 5, which is convenient and quick. Then the filter plate 5 can be cleaned.
[0055] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
