Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand processing, and particularly relates to a quartz sand vibrating sieving device. Background Art

[0002] Quartz sand is a product obtained by crushing quartz stone multiple times. Among them, due to multiple crushings, the particle sizes of quartz sand are not the same. Therefore, it is necessary to use vibrating screens with different mesh numbers to achieve classification and screening.

[0003] For example, the patent with the publication number CN216420121U discloses a multi-stage vibrating sieve for the particle size of modified silica sand. This patent uses a vibration motor as the vibration power source, and uses primary vibrating sieve plates, secondary vibrating sieve plates, and tertiary vibrating sieve plates with different pore diameters to screen modified silica sand with different particle sizes and finally guide it out by a recovery pipe and a converging inclined plate to achieve four-stage screening of modified sand. However, in the technical solution, since it drives the multi-stage vibrating sieve plates to perform multiple sieving by vibrating the outer shell, in the actual sieving process, the entire vibration motor needs to support the entire vibrating outer shell, multi-stage vibrating sieve plates, and quartz stones located on the multi-stage vibrating sieve plates and the vibrating outer shell. Therefore, the overall load is large, the quality requirements for the vibration motor are high, and the vibration motor is easily damaged. In addition, in the actual vibration process, since the position of the vibrating sieve plate is fixed relative to the vibrating outer shell, some quartz stones will be stuck in the mesh holes of the vibrating sieve plate during the vibrating sieving process, resulting in a reduction in the sieving area of the vibrating sieve plate and seriously affecting the subsequent sieving efficiency. Summary of the Utility Model

[0004] In order to overcome one of the deficiencies of the prior art, the purpose of the utility model is to provide a quartz sand vibrating sieving device, which can effectively improve the sieving efficiency and the requirements for the driving equipment.

[0005] To solve the above problems, the technical solutions adopted by the utility model are as follows:

[0006] A quartz sand vibrating sieving device, comprising a frame, a plurality of vibrating sieve vibrating mechanisms and a discharging mechanism. A vibrating cavity is obliquely arranged on the frame. All the vibrating sieves are stacked in sequence in the vibrating cavity, and one end of all the vibrating sieves located at the discharging end is hinged on one end of the frame located at the discharging end of the vibrating cavity. The vibrating mechanism includes a driving motor, a cam installed on the output end of the driving motor and a driving frame. The driving motor is installed on the frame. The driving frame is vertically slidably installed on the frame. One end of the driving frame is eccentrically connected to the cam. A plurality of inclined guide grooves are arranged on the driving frame. Both sides of one end of all the vibrating sieves for feeding are slidably installed in the corresponding inclined guide grooves through sliders. The discharging mechanism is arranged at the lower end of the vibrating cavity, and the discharging mechanism can receive and separately discharge the materials discharged from different vibrating sieves.

[0007] Further, at least one of the inclined guide grooves has a spatial component parallel to the discharging direction of the vibrating sieve.

[0008] Further, the driving frame includes a cross bar and sliding rods arranged at both ends of the cross bar. The two sliding rods are respectively slidably installed on both sides of the frame. A plurality of the inclined guide grooves are arranged on each sliding rod. A driving rod is hinged in the middle of the cross bar, and one end of the driving rod is eccentrically hinged to the cam.

[0009] Further, a reducer is connected to the output end of the driving motor, and the cam is installed on the output end of the reducer.

[0010] Further, the discharging mechanism includes a collecting hopper and a plurality of discharging pipes. The collecting hopper is communicated and arranged at the lower end of the vibrating cavity. A plurality of partition plates are arranged on the collecting hopper. All the partition plates divide the collecting hopper into a plurality of feeding cavities. One end of each feeding cavity for feeding can receive the materials discharged from the discharging end of the corresponding vibrating sieve, and one end of each feeding cavity for discharging is communicated with the discharging pipe.

[0011] Further, a receiving tongue is arranged on one end of each partition plate close to the discharging end of the vibrating sieve, and the receiving tongue extends into the area between adjacent vibrating sieves in the vibrating cavity.

[0012] Further, a control valve is arranged on each discharging pipe.

[0013] Further, a feeding hopper is arranged at one end of the frame far from the discharging mechanism, and the feeding hopper is located above the uppermost vibrating sieve.

[0014] Further, the mesh number of the sieve meshes in all the vibrating sieves gradually increases from top to bottom.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] A quartz sand vibrating sieving device of the present utility model is provided with a vibration cavity inside the frame, which is convenient for installing multiple layers of vibrating sieves. The vibration cavity is fixed relative to the discharging mechanism. Therefore, during the discharging process, the material will not swing along with the vibrating sieve, ensuring stable discharging. Among them, a driving motor drives a driving frame to slide up and down through a cam. During the up and down sliding process of the driving frame, it can drive one end of the vibrating sieve for feeding to swing up and down around the other end to provide a reciprocating up and down motion. And an inclined guide groove is arranged on the driving frame. Therefore, it can effectively guide the upper end of the vibrating sieve to slide, enabling the vibrating sieve to have sufficient movement space. In this application, since only all the vibrating sieves need to be driven to operate, the overall load is reduced, the requirements for the driving motor are reduced, and the production cost is reduced. At the same time, by arranging the inclined guide groove on the driving frame, during the vibration process, the vibrating sieve can also vibrate up and down relative to the driving frame. Through the mutual vibration between the vibrating sieve and the inclined guide groove, the material stuck on the vibrating sieve can be effectively shaken off, which can improve the sieving efficiency to a certain extent.

Specific Embodiments

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Refer to Figures 1 to 3A vibrating sieving device for quartz sand is shown, which includes a frame 10, a plurality of vibrating screens 20, a vibrating mechanism 30 and a discharging mechanism 40. A vibrating cavity 11 is inclinedly arranged on the frame 10; all the vibrating screens 20 are stacked in sequence in the vibrating cavity 11, and one end of all the vibrating screens 20 located at the discharging end is hinged to the frame 10 at the discharging end of the vibrating cavity 11; the vibrating mechanism 30 includes a driving motor 31, a cam 32 installed on the output end of the driving motor 31 and a driving frame 33. The driving motor 31 is installed on the frame 10, the driving frame 33 is vertically slidably installed on the frame 10, one end of the driving frame 33 is eccentrically connected to the cam 32, and a plurality of inclined guide grooves 34 are arranged on the driving frame 33. Both sides of the feeding end of all the vibrating screens 20 are slidably installed in the corresponding inclined guide grooves 34 through sliders 21; the discharging mechanism 40 is arranged at the lower end of the vibrating cavity 11, and the discharging mechanism 40 can receive and separately discharge the materials discharged from different vibrating screens 20.

[0025] Among them, the vibrating cavity 11 is integrally inclined, mainly for facilitating discharging, and the discharging mechanism 40 is connected to the lower end of the vibrating cavity 11, so that the materials at the bottom of the vibrating screen 20 and the vibrating cavity 11 can automatically roll into the discharging mechanism 40 during vibration effectively. In addition, in the above embodiment, the inclination direction of the inclined guide groove 34 is selected according to actual requirements. For example, in this application, the inclination direction of the inclined guide groove 34 is generally the same as the inclination direction of the vibrating screen 20; actually, the inclination slope of the inclined guide groove 34 is greater than the inclination slope of the vibrating screen 20. Such a setting is mainly to enable the feeding end of the entire vibrating screen 20 to have sufficient moving space, so as to increase the vibration amplitude of the entire vibrating screen 20, and thus ensure the sieving quality of the entire vibrating screen 20. Of course, in some improved embodiments, the inclination direction of the inclined guide groove 34 is generally perpendicular to or obtuse with the inclination direction of the vibrating screen 20, and this can also realize the up and down vibration of the vibrating screen 20. Therefore, in the above embodiment, at least one spatial component of the inclined guide groove 34 is parallel to the discharging end direction of the vibrating screen 20, and such a setting can realize the relative movement between the feeding end of the vibrating screen 20 and the driving frame 33.

[0026] In one embodiment, in order to ensure the sieving quality and achieve graded sieving, the mesh numbers of the inner sieves of all the vibrating screens 20 gradually increase from top to bottom.

[0027] Furthermore, in order to facilitate feeding and avoid the materials colliding with the topmost feeding hopper 12 during the feeding process and causing jumping, which affects the final sieving quality, in one embodiment, a feeding hopper 12 is arranged at one end of the frame 10 away from the discharging mechanism 40, and the feeding hopper 12 is located above the topmost vibrating screen 20.

[0028] This quartz sand vibrating sieving device is provided with a vibration cavity 11 inside the frame 10, which is convenient for installing multiple layers of vibrating sieves 20. The vibration cavity 11 is fixed relative to the discharging mechanism 40. Therefore, during the discharging process, the material will not swing along with the vibrating sieve 20, ensuring stable discharging. Among them, the driving motor 31 drives the driving frame 33 to slide up and down through the cam 32. During the up and down sliding process of the driving frame 33, it can drive one end of the vibrating sieve 20 for feeding to swing up and down around the other end to provide a reciprocating up and down movement. There is an inclined guide groove 34 provided on the driving frame 33. Therefore, it can effectively guide the upper end of the vibrating sieve 20 to slide, enabling the vibrating sieve 20 to have sufficient movement space. In this application, since only all the vibrating sieves 20 need to be driven to operate, the overall load is reduced, the requirements for the driving motor 31 are reduced, and the production cost is reduced. At the same time, by providing the inclined guide groove 34 on the driving frame 33, during the vibration process, the vibrating sieve 20 can also vibrate up and down relative to the driving frame 33. Through the mutual vibration between the vibrating sieve 20 and the inclined guide groove 34, the material stuck on the vibrating sieve 20 can be effectively shaken off, which can improve the sieving efficiency to a certain extent.

[0029] Further referring to Figures 1 to 3 , in order to facilitate the description of how to perform up and down movement through the driving frame 33, in an embodiment of the present application, the driving frame 33 includes a cross bar 35 and sliding rods 36 provided at both ends of the cross bar 35. The two sliding rods 36 are respectively slidably installed on both sides of the frame 10. A plurality of the inclined guide grooves 34 are provided on each sliding rod 36. The middle of the cross bar 35 is hinged with a driving rod 37, and one end of the driving rod 37 is eccentrically hinged with the cam 32. The main purpose of providing the two sliding rods 36 is to enable both sides of the feeding end of the vibrating sieve 20 to be driven synchronously, making the vibrating sieve 20 more stable during the movement process and avoiding movement jamming. The design of the cross bar 35 serves the purpose of connecting and stabilizing the two sliding rods 36. In addition, during the actual movement process, the cross bar 35 and the two sliding rods 36 together form a C-shaped structure. When the driving motor 31 drives the cam 32 to rotate, the eccentric connection between the cam 32 and the driving rod 37 can drive the C-shaped structure formed by the cross bar 35 and the two sliding rods 36 to slide up and down on the frame 10, and then can drive the vibrating sieve 20 to swing up and down around its discharging end to achieve sieving.

[0030] Furthermore, in order to provide greater driving force and protect the driving motor 31, a speed reducer is connected to the output end of the driving motor 31, and the cam 32 is installed on the output end of the speed reducer.

[0031] Further referring to Figure 3, in order to better perform nesting and without affecting the vibration of each vibrating screen 20, the discharging mechanism 40 includes a collecting hopper 41 and a plurality of discharging pipes 42. The collecting hopper 41 is communicatively provided at the lower end of the vibrating cavity 11. A plurality of partition plates 43 are provided on the collecting hopper 41. All the partition plates 43 divide the collecting hopper 41 into a plurality of feeding cavities 44. One end of each feeding cavity 44 for feeding can receive the materials discharged from the discharging end of the corresponding vibrating screen 20, and one end of each feeding cavity 44 for discharging is communicated with the discharging pipe 42. In fact, in this application, all the discharging pipes 42 can exist independently or can be collectively arranged in a pipeline, which is selected according to actual needs. In this application, for the sake of simplicity of the structure, the discharging pipes 42 exist independently to facilitate extended arrangement. In addition, one side of the opening of the collecting hopper 41 is fixedly installed on the frame at the discharging lower end of the vibrating cavity 11, so as to facilitate docking the materials discharged from different vibrating screens 20. In addition, in the above-mentioned embodiment, the lowermost feeding cavity 44 is actually the bottom of the collecting hopper 41, so it can be directly discharged outward without a partition plate 43.

[0032] In the above improved embodiment, a receiving tongue 45 is provided at one end of each partition plate 43 close to the discharging end of the vibrating screen 20. The receiving tongue 45 extends into the area between adjacent vibrating screens 20 in the vibrating cavity 11. The main purpose of such a setting is to better receive the materials discharged from each vibrating screen 20 and prevent them from falling onto the next layer of vibrating screen 20. In fact, during actual use, the insertion amount of the receiving tongue 45 does not exceed one-sixth of the length of the vibrating screen 20, so as to prevent it from blocking the falling of the materials.

[0033] In an improved embodiment, in order to facilitate controlling the later discharging, a control valve 46 is provided on each discharging pipe 42.

[0034] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
