Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, and in particular to a screening type sand filtering equipment. Background Art

[0002] In the prior art, fine sand is a commonly used raw material in construction. In the actual construction process, in order to ensure the particle size of fine sand, it is usually necessary to manually shovel the sand onto the upper part of the standing screen for sand filtering. However, the efficiency of this kind of sand filtering is not only affected by the intensity of manual labor, but also the sand filtering operation is interrupted due to the need to collect the filtered sand, resulting in a significant decrease in the sand filtering efficiency. Therefore, how to effectively improve the sand filtering efficiency is particularly important. Utility Model Content

[0003] The problem to be solved by the present application is that the existing fine sand material needs to be screened manually before use, and due to the influence of manual labor intensity, the continuous stability of the sand filtering efficiency cannot be guaranteed.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0014] The present application relates to a screening sand filter device, such as Figure 1-6 As shown, the sand filtering equipment includes a frame 3 for serving as a basic support, a screen frame 1 for performing screening operations is arranged on the top of the frame 3, and in order to facilitate the continuous screening operation of fine sand material, a screening assembly 5 detachably connected thereto is arranged inside the screen frame 1, and in order to facilitate the loading and unloading operation of the screening assembly 5, suspension assemblies 4 for hoisting and fixing the screen frame 1 are respectively arranged around the screen frame 1, and a driving assembly 2 for driving the screen frame 1 to perform reciprocating screening motion is arranged at the bottom of the screen frame 1, and in order to avoid the fine sand material and impurities after screening from being mixed together again, one end of the screening assembly 5 is a qualified material port 8 for discharging the fine sand material, and the other end of the screening assembly 5 is a discarded material port 9 for discharging impurities, thereby effectively avoiding secondary mixing of the fine sand material and impurities.

[0015] The screening component 5 includes a screen 15 and a screen plate 16. The screen 15 is arranged in the upper half of the screening component 5, and the screen plate 16 is arranged directly below the screen 15. The surface of the screen 15 is arranged in parallel with the screen frame 1, and the surface of the screen plate 16 is arranged at an angle of -3 to -5°, preferably -4.5°. The direction of movement of fine sand material on the upper part of the screen 15 is taken as the positive direction. Since there is a negative angle between the screen plate 16 and the screen frame 1, fine sand material with a qualified particle size will pass through the screen 15 and then fall to the upper part of the screen plate 16. Then, under the action of the inclined screen plate 16 and the gravity of the fine sand material itself, it will be discharged along the surface of the screen plate 16 along the qualified material port 8 at one end of the screen plate 16, while impurities with larger particle sizes will continue to move forward along the screen 15 and then be discharged from the waste material port 9 at the end of the screen 15.

[0016] In order to increase the screening rate of fine sand, the screen frame 1 is arranged at an angle of 1 to 3° relative to the horizontal plane, preferably 2°, so that the fine sand falling on the surface of the screen 15 to be screened can increase the gravitational potential energy and thus increase the movement speed.

[0017] The suspension assembly 4 includes a base block 18, a supporting ring 19, a hook 17, and a spring 20. The base block 18 is fixedly arranged at the middle position of the outer side of the screen frame 1. A supporting ring 19 rotatably connected to the base block 18 is arranged on one side of the base block 18, and a retractable hook 17 is arranged inside the supporting ring 19. The end of the hook 17 is connected to the screen 15, so as to suspend and pull the screen 15. In order to realize the pre-tightening effect of the hook 17, a spring 20 abutting against the supporting ring 19 is added to the other end of the hook 17, so as to realize the pre-tightening operation of the hook 17 under the action of the spring 20.

[0018] The driving assembly 2 includes a motor 14, a shaft 13, a balance wheel 12, a rocker arm 11, and a bracket 10. The motor 14 is arranged on one side of the lower part of the frame 3 to provide driving force, and the shaft 13 connected to the output shaft of the motor 14 is arranged on the upper part of the frame 3 through a bearing seat. In order to be able to drive the screening assembly 5 to move with the help of the shaft 13, a rocker arm 11 is added between the shaft 13 and the screen plate 16. In order to prevent the rocker arm 11 from getting stuck during operation, a balance wheel 12 is added between the rocker arm 11 and the shaft 13 to connect the two, and a bracket 10 is added between the rocker arm 11 and the screen plate 16 to connect the two.

[0019] In order to enable the screening assembly 5 to be driven by the swing rod 11 and then the frame 3 to perform a stable directional swing operation, a supporting plate 6 and a swing arm 7 for connection are respectively provided around the screen frame 1. The supporting plate 6 is fixedly connected to the screen frame 1, and the swing arm 7 is movably connected between the supporting plate 6 and the frame 3. With the help of the limiting effect of the swing arm 7, the stability of the screening assembly 5 during swinging is improved.

[0020] When in use, the fine sand material to be screened is poured into the screen frame 1, and then the motor 14 drives the shaft rod 13 to swing back and forth, and the shaft rod 13 will pull the swing rod 11 through the balance wheel 12 to perform a synchronous swing operation, and then the swing rod 11 will drive the screen plate 16 and the screen mesh 15 connected to the bracket 10 to perform a synchronous reciprocating swing operation. At this moment, the fine sand material to be screened on the upper part of the screen mesh 15 will produce a directional movement, and in the process of movement, the fine sand material with a particle size smaller than the aperture of the screen mesh 15 falls to the surface of the screen plate 16, and because the screen plate 16 is arranged inclined, the qualified fine sand material falling on the surface of the screen plate 16 is discharged along the qualified material port 8 at one end of the screen plate 16 under the action of its own gravity, and the impurities with larger particle sizes continue to move forward along the screen mesh 15 until they are discharged from the waste material port 9 at one end of the screen mesh 15, thereby avoiding the secondary mixing of fine sand material and impurities with the help of the separately arranged qualified material port 8 and waste material port 9, and at the same time, it also replaces the manual uniform and stable fine sand material screening operation.
