[0002] Sand making machines are used for crushing ore materials and are widely used in many fields such as metallurgy, building materials, highways, railways, water conservancy and chemical industries. The sand making machine includes a vibrating screen to screen the crushed sand and gravel aggregates. During the dry process of screening sand and gravel, a large amount of dust is generated, and it is usually necessary to install a dust removal device on the vibrating screen. During the wet process of screening sand and gravel, it is usually necessary to install a spray device on the vibrating screen. In the prior art, it is usually necessary to install one of the dust removal device and the spray device based on the required sand making process. When the sand making process needs to be changed, the original structure is dismantled and the new structure is reinstalled. For example, when it is necessary to switch from dry sand making to wet sand making, it is necessary to first dismantle the original dust removal device and then install the spray device on the upper side of the vibrating screen. Or, when it is necessary to switch from wet sand making to dry sand making, it is necessary to dismantle the original spray device and then install the dust removal device on the vibrating screen. The operation process is time-consuming and labor-intensive. Summary of the Invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] The following combination Figures 1 to 4 A vibrating screen assembly and sand making equipment provided by an embodiment of the present invention are described. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation to the present invention.

[0035] An embodiment of the first aspect of the present invention provides a vibrating screen assembly, such as Figure 1 and Figure 2 As shown, the vibrating screen assembly includes:

[0036] The vibrating screen body 100 includes a screen cavity;

[0037] The dust removal device 200 is in communication with the sieve cavity and is used to remove dust from the sieve cavity;

[0038] The spraying device 300 is arranged in the sieve cavity and is used to spray liquid into the sieve cavity to perform wet sand making.

[0039] The vibrating screen assembly provided by the present invention includes a vibrating screen body 100, a dust removal device 200 and a spray device 300. The vibrating screen body 100 includes a sieve cavity. The sand and gravel are vibrated and screened in the sieve cavity. The dust removal device 200 and the spray device 300 are connected and arranged in the sieve cavity. In other words, the dust removal device 200 and the spray device 300 are connected and arranged in the sieve cavity at the same time. When dry sand making is required, the spray device 300 is closed to stop spraying, and the dust removal device 200 is opened so that the dust in the sieve cavity is removed by the dust removal device 200; when wet sand making is required, the dust removal device 200 is closed to stop dust removal, and the spray device 300 is opened so that the spray device 300 sprays water or other liquids into the sieve cavity.

[0040] Through this structural setting, when the sand making process needs to be switched, there is no need to dismantle and reinstall the dust removal device 200 or the spray device 300. It is only necessary to adjust the working status of the dust removal device 200 and the spray device 300, which saves time and effort in the operation process.

[0041] In one embodiment of the present invention, the vibrating screen body 100 further includes a housing 110 and a plurality of vibrating screen bodies 130. A screen cavity is formed inside the housing 110. The vibrating screen bodies 130 are spaced apart and arranged in the screen cavity from top to bottom.

[0042] For example, Figure 1 As shown, a sieve cavity is formed within the housing 110. The screening process of the sand and gravel aggregate is carried out within the sieve cavity. In this embodiment, three vibrating screen bodies 130 are spaced apart from each other in the sieve cavity of the housing 110 from top to bottom. The sieve apertures of the different vibrating screen bodies 130 have different diameters to screen out sand and gravel aggregates of different qualities. A discharge port is provided on the right side of the housing 110, through which the target sand and gravel aggregates, after being screened by the vibrating screen bodies 130, are discharged.

[0043] In one embodiment of the present invention, the dust removal device 200 includes a dust cover 210, a dust collector, and an induced draft fan. The housing 110 has a top opening. The dust cover 210 is positioned over the top opening and is provided with an inlet 500 and a dust removal port 220. The inlet 500 communicates with the sieve cavity. The dust removal port 220 is connected to the dust collector, which in turn is connected to the induced draft fan.

[0044] For example, Figure 1 and Figure 2As shown, the top of the housing 110 is provided with a top opening. A dust shield 210 is provided at the top opening. The dust shield 210 is provided with an inlet 500. The inlet 500 is connected to the sieve cavity so that material can be fed into the sieve cavity through the inlet 500. The inlet material is located at the left end of the dust shield 210, or in other words, the inlet 500 is located on the upper left side of the sieve cavity. The outlet is located on the right side of the housing 110, or in other words, the outlet is located on the right side of the sieve cavity. The vibrating screen bodies 130 are arranged in an inclined direction with the left side higher and the right side lower, and each vibrating screen body 130 is parallel to each other. The dust shield 210 is also provided with a dust removal port 220. The dust removal port 220 is connected to the dust collector through a dust removal pipeline. The dust collector is connected to an induced draft fan to provide the dust collector with power to absorb dust. During the dry sand making process, the induced draft fan and the dust collector are turned on, and the dust generated during the screening of sand and gravel aggregates is sucked into the dust collector.

[0045] In one embodiment of the present invention, the dust removal port 220 is rotatably connected to a dust removal baffle that can be flipped and switched between a dust removal blocking position and a dust removal opening position.

[0046] In the dust removal blocking position, the dust removal baffle flips toward the side close to the dust removal port 220 to close the dust removal port 220; in the dust removal opening position, the dust removal baffle flips toward the side away from the dust removal port 220 to open the dust removal port 220.

[0047] For example, the dust removal baffle is rotatably connected to the inner side of the dust cover 210 in correspondence with the dust removal port 220. The dust removal baffle can be flipped relative to the dust cover 210 to switch between a dust removal blocking position and a dust removal open position. When dry sand making is required, the dust removal baffle is flipped to a position that avoids the dust removal port 220, so that the sieve cavity and the dust removal port 220 are connected to each other. The dust collector and the induced draft fan are turned on, and the spray device 300 is turned off. At this time, turning on the dust collector and the induced draft fan can achieve the dust removal effect required for dry sand making. When wet sand making is required, the dust removal baffle is flipped to a position that blocks the dust removal port 220, so that the sieve cavity and the dust removal port 220 are blocked from each other. The dust collector and the induced draft fan are turned off, and the spray device 300 is turned on. At this time, the spray device 300 can spray water into the sieve cavity, and the muddy water generated during the sand and gravel screening process cannot enter the dust removal port 220, thereby effectively protecting the dust collector.

[0048] In one embodiment of the present invention, the vibrating screen assembly further includes a base 700. The vibrating screen body 100 further includes support columns 120. The housing 110 is connected to the base 700 via the support columns 120. The dust removal device 200 further includes support rods 230 and elastic connectors 600. The dust cover 210 is connected to the base 700 via the support rods 230, and the edge of the dust cover 210 is connected to the edge of the top opening via the elastic connector 600.

[0049] For example, Figure 1 and Figure 4 As shown, the vibrating screen assembly also includes a base 700, which is supported and fixed to the ground. A plurality of support columns 120 are arranged at intervals between the shell 110 and the base 700. One end of each support column 120 is welded to the shell 110, and the other end of each support column 120 is connected to the base 700 by screws or other fasteners. A plurality of support rods 230 are arranged at intervals between the dust cover 210 and the base 700. One end of each support rod 230 is welded to the dust cover 210, and the other end of each support rod 230 is connected to the base 700 by screws or other fasteners. During the vibration of the vibrating screen body 100, its shell 110 will also vibrate to a certain extent. The top opening edge of the shell 110 is connected to the dust plate by an elastic connector 600. For example, the elastic connector 600 includes but is not limited to a multi-stage elastic rubber connecting sleeve. Thus, on the one hand, the dust shielding effect of the dust shield 210 can be improved, and on the other hand, the dust shield 210 and the shell 110 can be effectively prevented from being damaged during the screening vibration process through the form of soft connection.

[0050] In one embodiment of the present invention, the spray device 300 includes a plurality of spray pipes 310. Each spray pipe 310 is connected to the inner side of the dust shield 210 at intervals. A plurality of spray holes 312 are arranged on the spray pipe 310.

[0051] Furthermore, in one embodiment of the present invention, the spray pipe 310 is a square spray pipe. The square spray pipe includes a fixed connection surface and a spray surface 311. The fixed connection surface is attached to the inner side of the dust cover 210. The spray holes 312 are arranged on the spray surface 311.

[0052] For example, Figure 2 and Figure 3 As shown, along the extension direction of the vibrating screen body 130, or in other words, along the direction from the feed port 500 to the discharge port, a plurality of square spray pipes are arranged at intervals on the inner side of the dust cover 210. The upper surface of the square spray pipe is a fixed connection surface. The fixed connection surface is attached to the inner side of the dust cover 210, and its four edges are welded to the dust cover 210 to enhance the connection strength between the two. In this embodiment, the opposite surface of the fixed connection surface is the injection surface 311. A plurality of spray holes 312 are provided on the injection surface 311. For example, the spray holes 312 are arrayed in the form of multiple rows and columns on the injection surface 311 to enhance the uniformity of the injection of the injection surface 311, thereby enhancing the sand washing effect of wet sand making, and making the flow of sand and gravel aggregates on the vibrating screen body 130 more uniform, thereby effectively protecting the vibrating screen body 130.

[0053] It should be noted that the above embodiment is merely an illustrative embodiment of the present invention and does not constitute any limitation on the present invention. The spray surface 311 on the square spray pipe includes but is not limited to the opposite surface of the fixed connection surface, and can be any one or more planes other than the fixed connection surface.

[0054] In one embodiment of the present invention, a slide groove is provided on the injection surface 311. A nozzle baffle is slidably connected in the slide groove. The nozzle baffle can slide and switch between a nozzle blocking position and a nozzle opening position.

[0055] In the nozzle blocking position, the nozzle baffle blocks each nozzle 312 to separate each nozzle 312 from the sieve cavity; in the nozzle opening position, the nozzle baffle avoids each nozzle 312 to connect each nozzle 312 with the sieve cavity.

[0056] Specifically, the size of the spray hole baffle is adapted to the layout range of the spray holes 312 on the injection surface 311. The injection surface 311 is provided with a slide groove, and the spray hole baffle is slidably connected to the slide groove. When dry sand making is required, the spray hole baffle is slid to the spray hole blocking position so that the spray hole baffle blocks all the spray holes 312 on the corresponding injection surface 311. Furthermore, it can prevent the dust generated during the dry sand making process from clogging the spray holes 312 in the inlet spray holes 312. When wet sand making is required, the spray hole baffle is slid to the spray hole opening position so that all the spray holes 312 on the injection surface 311 are connected to the sieve cavity. Furthermore, the water transported by the square spray pipe is sprayed into the sieve cavity through each spray hole 312.

[0057] In addition, a limiting structure may be provided between the spray hole baffle and the slide groove to prevent the spray hole baffle from falling off the slide groove.

[0058] It should be noted that the above embodiment is merely an illustrative embodiment of the present invention and does not constitute any limitation on the present invention. In other embodiments of the present invention, a nozzle baffle may be rotatably connected to the injection surface 311. The nozzle baffle can be flipped relative to the injection surface 311 to block or avoid the nozzle 312. When the nozzle baffle blocks the nozzle 312, it is secured to the injection surface via a snap fastener.

[0059] In another embodiment of the present invention, the dust shield 210 is further provided with a viewing window 400. A monitoring device is installed at the viewing window 400. The monitoring device is used to monitor the vibration screening status of the sieve cavity. A flow control valve is provided on the spray pipe 310. The flow control valve controls the amount of water entering the sieve cavity through the spray pipe 310.

[0060] During actual use, staff can remotely monitor the vibration screening status within the sieve cavity through monitoring equipment. For example, during wet sand production, staff can monitor the spraying status of the spray pipe 310 and the screening status of the sand and gravel aggregate through monitoring equipment. Based on these conditions, the opening size of the flow control valve can be adjusted in real time to improve the quality of wet sand production.

[0061] An embodiment of the second aspect of the present invention provides a sand making device comprising the vibrating screen assembly as described above.

[0062] For example, in one embodiment of the present invention, the sand making equipment includes a sand making machine.

[0063] Furthermore, in the sand making equipment provided by the present invention, since it includes the vibrating screen assembly as described above, it also has the advantages as described above.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
