Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machine-made sand powder control, in particular to a water-washing powder control device for machine-made sand processing in a gravel field. Background Art
[0002] In the production process of machine-made sand, the raw sand and gravel often contain high dust content and agglomeration, which not only increases the complexity and energy consumption of the subsequent sand washing process, but may also have an adverse effect on the normal operation of the production equipment, such as clogging the pipeline and wearing the equipment.
[0003] Traditional gravel production processes typically use simple crushing equipment to crush the sand and gravel. However, this method often fails to effectively remove dust and loose lumps from the sand and gravel. Furthermore, the lack of effective dispersion and collision mechanisms during the falling process of the crushed sand and gravel makes it difficult to fundamentally resolve the dust and clumping issues. Furthermore, the dust generated during the crushing process easily escapes into the air, posing a threat to the working environment and the health of operators.
[0004] Therefore, this application provides a device for washing and controlling powder of machine-made sand in a gravel field to meet the needs. Utility Model Content
[0005] The technical problem addressed by this utility model is to provide a water-washing and dust-control device for machine-made sand in gravel quarries. This device addresses the existing problem of using simple crushing equipment to crush sand and gravel in the existing machine-made sand processing process. However, this method often fails to effectively remove dust and loose lumps from the sand and gravel. Furthermore, the lack of effective dispersion and collision mechanisms during the falling process of the crushed sand and gravel makes it difficult to fundamentally resolve the dust and agglomeration issues. Furthermore, the dust generated during the crushing process easily escapes into the air, posing a threat to the working environment and the health of operators.
[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0007] A device for controlling powder by washing and washing machine-made sand in a gravel field comprises: a box body with a hopper on the top and a discharge bin on the bottom; a crushing assembly comprising a support rod fixed inside the box body, and a baffle fixed above the support rod by a first spring, the baffle being an inverted V-plate structure for dispersing falling sand and gravel materials; a dust suction assembly comprising a dust suction pipe arranged on the side wall of the box body for connecting to a dust removal device to suck dust inside the box body.
[0008] Preferably, there are a plurality of crushing components, which are distributed in a staggered rectangular array in the vertical direction.
[0009] Preferably, the dust suction pipe is arranged at an angle and tilts downward from the outside to the inside on the side wall of the box.
[0010] Preferably, it also includes an inspection port, which is opened on the side wall of the box body and completely covers the plurality of crushing components.
[0011] Preferably, it also includes a sealing plate, which is sealed and connected to the inspection port by bolts.
[0012] Preferably, it also includes a protective plate, which is rotatably connected to the inner wall of the box, and the protective plate is located above the tube body of the dust suction pipe inside the box, and the bottom of the protective plate is connected to the top of the dust suction pipe wall through a second spring.
[0013] Preferably, the vertical projection pattern of the protective plate completely covers the vertical projection pattern of the tube body of the dust collection tube located inside the box.
[0014] Preferably, a protective component is also included, including a railing and a screen. There are several railings, and they are all fixed on the inner wall of the nozzle of the dust suction pipe inside the box; the screen is arranged at one end of the dust suction pipe near the railing.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects:
[0016] 1. By installing several staggered crushing assemblies consisting of support rods, a first spring, and baffles, the sand and gravel collide with the baffles multiple times during the falling process, effectively loosening lumps in the sand and gravel and removing attached dust. At the same time, the dust collection assembly promptly extracts dust from the interior of the box, significantly reducing the dust content in the sand and gravel, facilitating subsequent sand washing operations, improving the working environment, and protecting the health of operators.
[0017] 2. By setting the first spring, it not only provides a buffer for the collision between the sand and gravel and the baffle, reducing the wear of the equipment, but also further promotes the loosening of the sand and gravel through the vibration of the spring, improves the crushing effect, and ensures the quality of the finished sand.
[0018] 3. The suction pipe is set at an angle and supplemented by protective components such as protective plates and screens, which effectively prevents sand and gravel from directly impacting the suction pipe and reduces the risk of blockage. At the same time, the dual protection of the grille railing and screen further ensures that large particles of sand and gravel will not enter the suction pipe, thereby improving the efficiency of the suction component and the service life of the equipment.
[0019] 4. The inspection port covers all crushing components, making it convenient for operators to carry out daily inspection and maintenance of the equipment, thereby improving the reliability and operating efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0028] The following describes in detail a device for washing and controlling powder in crushed stone processing machine-made sand provided by the present invention, in conjunction with the accompanying drawings and specific embodiments. It is also noted that, to provide a more detailed description, the following embodiments are best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternatives to implement them. Furthermore, the accompanying drawings are provided solely for the purpose of describing the embodiments in greater detail and are not intended to limit the present invention to any specific extent.
[0029] like Figure 1 - Figure 5As shown, the embodiment of the utility model provides a device for controlling powder by washing and washing machine-made sand in a gravel field, comprising: a box body 1, a hopper 2 is provided on the top for feeding sand and gravel to be crushed, and a discharge bin 3 is provided on the bottom for discharging the crushed sand and gravel; a crushing assembly, comprising a support rod 7 fixed inside the box body 1, and a baffle 9 fixed above the support rod 7 by a first spring 8, the baffle 9 is an inverted V-plate structure, which is used to disperse the falling sand and gravel materials, and there are several crushing assemblies, which are distributed in an staggered rectangular array in the vertical direction, so as to ensure that the sand and gravel materials contact and collide with the baffle 9 in at least one of the crushing assemblies during the falling process inside the box body 1; a dust suction assembly, comprising a dust suction pipe 6 arranged on the side wall of the box body 1, which is used to connect a dust removal device to suck the dust inside the box body 1, and the dust removal device is preferably a bag dust collector, and the air is sucked to the outside by an air pump.
[0030] Among them, one end of the support rod 7 is vertically fixedly connected to the inner wall of the box body 1, and the single support rod 7 supports the fixed baffle 9 through multiple first springs 8, and there is a certain gap between the two ends of the baffle 9 and the inner wall of the box body 1 to ensure that sand and gravel can pass normally.
[0031] By setting up several crushing assemblies composed of support rods 7, first springs 8, and baffles 9 and distributed in an alternating manner, the sand and gravel will collide with the baffles 9 during the falling process, thereby loosening the lumps in the sand and gravel and separating the dust attached to the sand and gravel, and the dust separated from the sand and gravel is sucked and filtered out by the dust suction assembly, thereby reducing the dust content in the sand and gravel and facilitating the subsequent sand washing work; and by setting the first spring 8 to support the support rods 7 and the baffles 9, a certain buffering effect is played on the collision and contact between the sand and gravel and the baffles 9, and the collision of the sand and gravel causes the baffles 9 to vibrate self-excitedly, which can further improve the loosening effect of the agglomerated sand and gravel.
[0032] like Figure 2 As shown, the dust suction pipe 6 is tilted and tilted downward from the outside to the inside on the side wall of the box body 1 to prevent sand and gravel from falling directly into the dust suction pipe 6 and causing blockage. The tilted setting allows the sand and gravel that enter the dust suction pipe 6 to be discharged by themselves under the action of gravity.
[0033] like Figure 2 As shown, it also includes an inspection port 4, which is opened on the side wall of the box body 1, and the inspection port 4 completely covers several crushing components, making it easy to inspect and maintain all crushing components, wherein the inspection port 4 is opened on the side wall of the box body 1 away from the support rod 7 fixedly connected.
[0034] like Figure 1 As shown, it also includes a sealing plate 5, which is sealed and connected to the inspection port 4 through bolts to ensure the sealing of the side wall of the box body 1 and prevent dust from escaping during the crushing process and affecting the working environment.
[0035] like Figure 4 and Figure 5 As shown, it also includes a protective plate 11, which is rotatably connected to the inner wall of the box body 1, and the protective plate 11 is located above the tube body of the dust suction tube 6 inside the box body 1, and the bottom of the protective plate 11 is connected to the top of the tube wall of the dust suction tube 6 through the second spring 10; the vertical projection pattern of the protective plate 11 completely covers the vertical projection pattern of the tube body of the dust suction tube 6 inside the box body 1.
[0036] By setting a protective plate 11 above the dust suction pipe 6 inside the box 1, sand and gravel are prevented from directly colliding and wearing the dust suction pipe 6, and the impact of sand and gravel is buffered by setting a second spring 10, which effectively extends the service life of the protective plate 11.
[0037] like Figure 5 As shown, it also includes a protective component, including a railing 12 and a screen 13. There are several railings 12, and they are all fixed on the inner wall of the nozzle of the dust suction pipe 6 inside the box body 1; the screen 13 is arranged inside the dust suction pipe 6 near one end of the railing 12.
[0038] Due to the collision between the sand and gravel and the baffle 9, it will inevitably rebound, causing the sand and gravel to bounce into the dust suction pipe 6. By setting the grid-type railing 12, large particles of sand and gravel are initially blocked, and a screen 13 is set inside the dust suction pipe 6 for secondary sorting to prevent large particles of sand and gravel from entering the dust suction pipe 6, resulting in reduced efficiency of the dust suction component and waste of sand and gravel.
[0039] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.
[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
