Description

Technical Field

[0001] This utility model relates to the field of storage device technology, specifically a quartz sand storage device. Background Technology

[0002] Quartz sand is a granular material made from natural quartz or vein quartz through crushing, screening and other processes. Its main component is silicon dioxide, which usually contains more than 90%.

[0003] Because the amount of quartz sand stored at one time varies, the existing storage devices cannot change their spatial structure. As a result, when the quartz sand is insufficient, the storage devices occupy a lot of space, which is not conducive to space allocation. Furthermore, the large volume of the storage devices is also not conducive to transportation. Utility Model Content

[0004] The purpose of this invention is to provide a quartz sand storage device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quartz sand storage device, comprising a base, three sets of support legs fixedly connected to the upper part of the base, an outer storage tank fixedly connected to the upper part of the support legs, an inner storage tank slidably connected inside the outer storage tank, a discharge port fixedly connected to the lower center of the outer storage tank, a feed port fixedly connected to the upper center of the inner storage tank, two sets of connecting plates fixedly connected to the upper sides of the inner storage tank, two sets of mounting brackets fixedly connected to the upper sides of the base, threaded rods threadedly connected inside the mounting brackets, a rotating disk fixedly connected to the lower part of the threaded rods, the upper part of the threaded rod on the left side rotatably connected to the connecting plate, and a support pad fixedly connected to the upper part of the threaded rod on the right side.

[0006] Preferably, the lower side of the inner storage tank is provided with a ramp.

[0007] Preferably, a drop platform is provided on the lower side of the interior of the outer storage tank.

[0008] Preferably, an installation plate is fixedly connected to the lower inner side of the inner storage tank, an outer support rod is fixedly connected to the upper part of the installation plate, an inner support rod is slidably connected inside the outer support rod, a falling cone is fixedly connected to the upper part of the inner support rod, and several sets of buffer grooves are opened on the outer side of the falling cone.

[0009] Preferably, a lifting plate is fixedly connected to the lower part of the inner support rod, and a spring is fixedly connected between the lifting plate and the inner wall of the outer support rod, with the spring sleeved on the inner wall of the inner support rod.

[0010] Preferably, four sets of omnidirectional wheels are fixedly connected to the lower part of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a rotating disc to drive the threaded rods on both sides to move up and down. The threaded rod on the left side drives the inner storage tank to move up and down along the inside of the outer storage tank through the connecting plate. The threaded rod on the right side drives the support pad to fit tightly against the lower part of the connecting plate to support the inner storage tank. The height of the storage device can be adjusted according to the amount of quartz sand stored, thereby changing the space occupied by the equipment and facilitating the transportation of the storage device.

[0013] 2. This utility model also allows quartz sand falling from the feed inlet to slide outward from the top of the falling cone. Due to the buffering effect of multiple buffer grooves on the falling speed, when the quartz sand falls into the falling cone, the quartz sand drives the lifting plate to move downward through the inner support rod, thereby stretching the spring and buffering the impact. Furthermore, due to the reciprocating motion of the spring, it is more conducive to shaking off the residual quartz sand at the falling cone, thus preventing the quartz sand from damaging the storage device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: a quartz sand storage device, including a base 1, three sets of support legs 2 fixedly welded to the upper part of the base 1, an outer storage tank 3 fixedly welded to the upper part of the support legs 2, an inner storage tank 4 slidably installed inside the outer storage tank 3, a discharge port 11 fixedly welded to the lower middle part of the outer storage tank 3, and a feed port 10 fixedly welded to the upper middle part of the inner storage tank 4. By feeding quartz sand through the feed port 10, the inner storage tank 4 is moved up and down along the inner storage tank 3, thereby changing the overall height of the device. When quartz sand is needed, the discharge port 11 is opened by controlling the solenoid valve to allow the quartz sand to be used. For sand discharge, two sets of connecting plates 5 are fixedly welded to the upper two sides of the inner storage tank 4, and two sets of mounting brackets 6 are fixedly welded to the upper two sides of the base 1. Threaded rods 7 are installed inside the mounting brackets 6, and a rotating disk 8 is fixedly welded to the lower part of the threaded rods 7. The upper part of the left threaded rod 7 is rotatably connected to the connecting plate 5, and a support pad 9 is fixedly welded to the upper part of the right threaded rod 7. By rotating the rotating disk 8, the threaded rods 7 on both sides are moved up and down. The left threaded rod 7 moves the inner storage tank 4 up and down through the connecting plate 5, and the right threaded rod 7 moves the support pad 9 to fit tightly against the lower part of the connecting plate 5 to support the inner storage tank 4.

[0020] An inclined platform 13 is provided on the lower side of the inner storage tank 4 to facilitate its downward movement and insertion into the quartz sand. A drop platform 14 is provided on the lower side of the inner storage tank 3 to facilitate the quartz sand falling into the discharge port 11 for discharge. An installation plate 15 is fixedly welded to the lower inner side of the inner storage tank 4, and an outer support rod 16 is fixedly welded to the upper part of the installation plate 15. An inner support rod 17 is slidably installed inside the outer support rod 16, and a drop cone 18 is fixedly welded to the upper part of the inner support rod 17. Several sets of buffer grooves 19 are provided on the outer side of the drop cone 18. The quartz sand falling into the feed port 10 slides outward from the upper part of the drop cone 18. Multiple buffer grooves 19 buffer the falling speed to prevent the quartz sand from damaging the storage device; a lifting plate 21 is fixedly welded to the lower part of the inner support rod 17, and a spring 20 is fixedly welded between the lifting plate 21 and the inner wall of the outer support rod 16. The spring 20 is sleeved on the inner wall of the inner support rod 17. When the quartz sand falls into the falling cone 18, the quartz sand drives the lifting plate 21 to move downward through the inner support rod 17, thereby stretching the spring 20, which buffers the falling. Due to the reciprocating motion of the spring 20, it is more conducive to shaking off the residue at the falling cone 18; four sets of universal wheels 12 are threaded on the lower part of the base 1 to facilitate the transportation of quartz sand in the storage device.

[0021] Working principle: When in use, the rotating disc 8 drives the threaded rods 7 on both sides to move up and down. The left threaded rod 7 drives the inner storage tank 4 to move up and down along the inside of the outer storage tank 3 through the connecting piece 5. The right threaded rod 7 drives the support pad 9 to stick tightly to the lower part of the connecting piece 5 to support the inner storage tank 4. The quartz sand falling in through the feed port 10 slides outward from the top of the falling cone 18. Due to the buffering of the multiple sets of buffer grooves 19, when the quartz sand falls into the falling cone 18, the quartz sand drives the lifting plate 21 to move downward through the inner support rod 17, thereby stretching the spring 20 and buffering the impact. Due to the reciprocating motion of the spring 20, it is more conducive to shaking off the residual quartz sand at the falling cone 18, thus preventing the quartz sand from damaging the storage device.
