Description

Technical Field

[0001] This utility model relates to the technical field of sand storage tanks for cyclone sand separators, and specifically to a sand storage tank for a cyclone sand separator. Background Technology

[0002] A hydrocyclone sand separator is designed based on the sieving principle of solid particles rotating within a fluid. It integrates cyclone and filtration, achieving sand removal, turbidity reduction, and solid-liquid separation in water treatment. The hydrocyclone sand separator utilizes centrifugal separation. When water enters the equipment tangentially from the inlet under pressure, it generates a strong rotational motion. Due to the density difference between sand and water, the combined effects of centrifugal force, centripetal force, buoyancy, and fluid drag cause the less dense water to rise and exit through the outlet. The denser sand particles, under the influence of fluid inertia, centrifugal force, and their own gravity, fall along the cone wall into the bottom of the device. When the accumulated debris at the bottom of the cone reaches a certain level, the valve below is opened, allowing the sand to flow out of the hydrocyclone sand separator under the action of the water flow, thus achieving the purpose of sand removal.

[0003] Publication (Announcement) No.: CN209759073U discloses a cyclone sand separator discharge device, including a sand storage tank, which is a horizontally placed cylindrical shape. The sand storage tank has a sand inlet at the upper end and a sand discharge outlet at the lower end. A rotating shaft is horizontally arranged inside the sand storage tank. Both ends of the rotating shaft are rotatably connected to the side wall of the sand storage tank. One end of the rotating shaft extends outside the sand storage tank and can be fixed by a locking mechanism. Two discs are sleeved on both sides of the rotating shaft. The discs are tightly attached to the inner wall of the sand storage tank and can rotate. Multiple blades are arranged around the rotating shaft. The blades are located between the discs and the discs, and the blade ends are tightly attached to the inner wall of the sand storage tank and can rotate. The area enclosed by two adjacent blades, the discs, and the rotating shaft forms a sand storage hopper.

[0004] In the prior art:

[0005] First, the debris separated by the existing hydrocyclone sand separator accumulates directly at the bottom of the conical tank. Since there is no mechanism or device to prevent the sand from rising, the rotating water flow often picks up and carries the sand away, resulting in the discharge of sewage containing a large amount of debris.

[0006] Secondly, the debris and gravel separated by the cyclone separator accumulate at the bottom of the conical tank, concentrating in the center and sliding outwards. During the accumulation process, the debris and gravel at the bottom of the conical tank will accumulate in a cone-shaped structure, making the space around the conical tank ineffective. This causes the top layer of gravel in the cone-shaped structure to be easily swept away again by the rotating water flow and discharged from the outlet, affecting the cleaning purpose of the cyclone screening.

[0007] Third, the debris and gravel fall in a scattered manner when screened out, causing the debris and gravel to accumulate in the cone of the tank and fall in a scattered and slow manner, which affects the efficient collection and recycling of debris and gravel.

[0008] Therefore, a sand storage tank for a cyclone sand separator is needed. Utility Model Content

[0009] To address the problems existing in the prior art, this utility model provides a sand storage tank for a cyclone sand separator, aiming to improve the efficiency of rope-type length calibration and increase the product calibration accuracy, thereby avoiding inaccurate product length measurement parameters.

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a sand storage tank for a cyclone sand separator, comprising an upper tank, a lower tank, and a pressure pump. The bottom of the upper tank is bolted to the lower tank, and the bottom of the lower tank is connected to the pressure pump via a pipe. An opening and closing valve is provided at the connection between the lower tank and the pipe. A support frame is provided in the upper part of the interior of the upper tank, and a cone-shaped dispersion component is provided in the upper part of the support frame. A spiral guide plate is provided on the inner surface of the upper tank at the bottom of the support frame, and the bottom of the spiral guide plate extends to the top of the interior of the lower tank.

[0011] Preferably, the support frame is arranged in a "cross" shape and a reinforcing plate is provided in the middle. The dispersion component includes several concave arc-shaped acceleration plates. The arc-shaped acceleration plates are evenly distributed along the axial direction of the upper tank cylinder to form a conical hollow structure. The arc-shaped acceleration plates are fixedly installed between each other by stiffening plates.

[0012] Preferably, the support frame and the dispersion components are made of R31233 alloy.

[0013] Preferably, the curvature of the arc-shaped accelerator plate is set to 90 degrees.

[0014] In summary, this utility model provides a sand storage tank for a cyclone sand separator. A dispersing component collects sand and debris, accelerating their downward sliding. The debris flows to a spiral guide plate located at the bottom of the upper tank, where it is swirled and slid into the lower tank. The dispersing component prevents the sand and debris from being carried out of the outlet by centripetal force, buoyancy, and fluid drag. The dispersing component acts as a barrier, and the debris is circumferentially dispersed before being accelerated out by the spiral guide plate and collected in the lower tank. This solves the problems of slow falling speed and scattered debris, achieving the technical effect of swirling transport by the spiral guide plate, allowing sand and debris to be collected in the lower tank.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown:

[0022] This utility model relates to a sand storage tank for a cyclone sand separator, comprising an upper tank 1, a lower tank 2, and a pressure pump 3. The bottom of the upper tank 1 is bolted to the lower tank 2, and the bottom of the lower tank 2 is connected to the pressure pump 3 via a pipe. An opening and closing valve 4 is provided at the connection between the lower tank 2 and the pipe. A support frame 5 is provided in the upper part of the interior of the upper tank 1, and a cone-shaped dispersion component 6 is provided in the upper part of the support frame 5. A spiral guide plate 7 is provided on the inner surface of the upper tank 1 at the bottom of the support frame 5, and the bottom of the spiral guide plate 7 extends to the inner top of the lower tank 2.

[0023] To address the technical problems in existing technologies, such as the swirling and swirling of sand and gravel, gaps around the bottom of the conical tank, uneven descent of the conical tank, and slow descent speed, this patent adopts the following technical structure: A support frame 5 is installed inside the tank at the bottom of the inlet of the upper tank cylinder 1. A conical dispersion component 6 is installed on the upper part of the support frame 5. When sand and gravel and debris swirl into the upper tank cylinder 1, the conical end of the dispersion component 6 disperses the sand and gravel and debris onto the body of the dispersion component 6. The dispersion component 6 collects the sand and gravel and debris, accelerates their downward sliding, and flows into the spiral guide at the bottom of the upper tank cylinder 1. Plate 7, through the spiral guide plate 7, swirls and slides to collect the sand and debris into the lower tank 2, thus achieving collection into the lower tank 2. The setting of the dispersion component 6 solves the problem that the sand and debris swirling out are carried out of the outlet again by the centripetal force, buoyancy and fluid drag force. The dispersion component 6 blocks the sand and debris, and the circumferential dispersion of the sand and debris is then accelerated out by the spiral guide plate 7 and collected into the lower tank 2. This solves the problems of slow falling speed and scattered falling, and achieves the technical effect of swirling conveying by the spiral guide plate 7, which can collect the sand and debris into the lower tank 2.

[0024] In at least one embodiment, the support frame 5 is arranged in a "cross" shape and a reinforcing plate 11 is provided in the middle. The dispersing component 6 includes several concave arc-shaped accelerating plates 12. The arc-shaped accelerating plates 12 are evenly distributed along the axial direction of the upper tank 1 to form a conical hollow structure. The arc-shaped accelerating plates 12 are fixedly installed by stiffening plates 13. Through the arc-shaped structure of the arc-shaped accelerating plates 12, sand and debris are collected in the arc-shaped groove of the arc-shaped accelerating plates 12. Under the action of gravity and swirling force, the sand and debris are accelerated to slide down. After being guided by the spiral guide plate 7, they are collected and transported to the lower tank 2, realizing the collection and concentration of sand and debris and effectively utilizing the storage space in the lower tank 2.

[0025] In at least one embodiment, to enhance the support of the support frame 5 and the dispersing component 6 for the swirling gravel and debris and to increase their wear resistance, both the support frame 5 and the dispersing component 6 are made of R31233 alloy.

[0026] In at least one embodiment, in order to enable the arc-shaped accelerator plate 12 to accelerate the swirling sand and debris to slide off most effectively, the arc of the arc-shaped accelerator plate 12 is set to 90 degrees.

[0027] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
