Description

Technical Field

[0001] The utility model belongs to the technical field of sand and gravel screening equipment, and specifically relates to a quartz sand screen. Background Art

[0002] Quartz sand screen is widely used in chemical, metallurgical, building materials and other industries for screening, filtering and separating quartz sand and other materials.

[0003] Traditional quartz sand screens often face some challenges during the screening process. Due to the high hardness and abrasiveness of quartz sand, the screens are often easily worn, which not only affects the screening efficiency but also limits the service life of the screens. What is more difficult is that traditional quartz sand screens are usually designed as an integral structure. Once local wear occurs, the entire screen needs to be replaced. This not only increases operating costs, but also causes a waste of resources. Utility Model Content

[0004] The purpose of the present invention is to provide a quartz sand screen, which can reduce the operating cost and improve the resource utilization efficiency.

[0005] The technical solutions adopted in this utility are as follows:

[0006] A quartz sand screen comprises a mounting plate, a plurality of first mounting grooves are provided on the top of the mounting plate, a connecting groove is provided on the inner bottom wall of the first mounting groove, a rotating shaft is rotatably installed on the inner wall of the first mounting groove, a rotating plate is fixed on the outer wall of the rotating shaft, torsion springs are provided on the outer wall of the rotating shaft and on both sides of the rotating plate, a second mounting groove is provided on one side of the rotating plate, a detachable plug-in plate is plugged into the inside of the second mounting groove, and the outer wall of the plug-in plate is slidably connected to the inner wall of the second mounting groove, a third mounting groove is provided on the top of the plug-in plate, a screen body is provided on the inner wall of the third mounting groove, a bolt is spirally screwed on the top of the plug-in plate, and a bottom side of the bolt passes through the plug-in plate and the rotating plate and extends into the mounting plate.

[0007] Furthermore, ramp plates are rotatably mounted on both sides of the mounting plate.

[0008] Furthermore, a plurality of iron sheets are arranged at the bottom of the ramp plate, and a plurality of magnets magnetically attracted to the iron sheets are arranged at the top of the mounting plate.

[0009] The technical effects achieved by this utility model are:

[0010] The practical quartz sand screen realizes the partial replacement function of the screen by cleverly arranging multiple detachable screen bodies on the mounting plate. When one of the screen bodies needs to be replaced due to wear, there is no need to replace the entire screen, but only the worn screen body needs to be easily disassembled and replaced, thereby reducing the operating cost and improving the resource utilization efficiency, bringing greater convenience and economic benefits to screening operations in the chemical, metallurgical, building materials and other industries.

[0016] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0017] like Figure 1-3As shown, a quartz sand screen comprises a mounting plate 1, a plurality of first mounting grooves 2 are provided on the top of the mounting plate 1, a connecting groove 3 is provided through the inner bottom wall of the first mounting groove 2, a rotating shaft 5 is rotatably installed on the inner wall of the first mounting groove 2, a rotating plate 4 is fixed on the outer wall of the rotating shaft 5, a torsion spring 6 is provided on the outer wall of the rotating shaft 5 and on both sides of the rotating plate 4, a second mounting groove 7 is provided on one side of the rotating plate 4, a detachable plug-in plate 8 is plugged into the interior of the second mounting groove 7, and the outer wall of the plug-in plate 8 is slidably connected to the inner wall of the second mounting groove 7, a third mounting groove 10 is provided through the top of the plug-in plate 8, a screen body 9 is provided on the inner wall of the third mounting groove 10, a bolt 11 is spirally screwed on the top of the plug-in plate 8, and the bottom side of the bolt 11 passes through the plug-in plate 8 and the rotating plate 4 and extends into the mounting plate 1, so as to facilitate the screen body 9 It is divided into multiple parts, and when a part is seriously worn, it is convenient to replace it, avoiding the need to replace a whole screen body 9 of the traditional screen body 9, which increases the operating cost and wastes resources. When the screen body 9 is replaced, the corresponding bolts 11 are first disassembled, because the torsion spring 6 drives the rotating plate 4 to rotate, so that the rotating plate 4 is rotated and separated from the first mounting groove 2, and then the plug-in plate 8 is pulled out from the second mounting groove 7, and the new plug-in plate 8 is inserted into the second mounting groove 7, and then the bolts 11 are passed through the plug-in plate 8 and the rotating plate 4 in turn and screwed into the mounting plate 1, so as to complete the installation and fixation of the screen body 9; slide rails are arranged on both sides of the plug-in plate 8, and the inner wall of the second mounting groove 7 is provided with a slide groove slidably connected to the slide rail, which is convenient for the plug-in sliding of the plug-in plate 8 in the second mounting groove 7, which is more practical;

[0018] like Figure 1-2 As shown, connecting ears 13 are fixed on the four corners of the outer wall of the mounting plate 1 to facilitate the connection between the mounting plate 1 and the vibrating screen machine;

[0019] like Figure 1-2 As shown, ramp plates 12 are rotatably installed on both sides of the mounting plate 1. The ramp plates 12 are arranged to place sand and gravel into the connecting gap, so that the sand and gravel can be accurately placed on the screen body 9, which is relatively perfect; a plurality of iron sheets 15 are arranged at the bottom of the ramp plate 12, and a plurality of magnets 14 magnetically attracted to the iron sheets 15 are arranged at the top of the mounting plate 1, which is convenient for fixing the ramp plate 12 on both sides of the top of the mounting plate 1, and also convenient for the ramp plate 12 to be rotated and separated from the top of the mounting plate 1, which is relatively practical;

[0020] like Figure 3 As shown, the inner walls of the first mounting groove 2 and the second mounting groove 7 are both provided with sealing rings, which increase the sealing of the connection between the first mounting groove 2 and the rotating plate 4 and the second mounting groove 7 and the plug-in plate 8, and prevent sand and gravel from falling into the connection seams, which is relatively perfect.
