Description

Technical Field

[0001] This application relates to the technical field of filtering devices, and particularly to a sand and gravel separation device. Background Art

[0002] In construction projects, a large amount of stone materials are used, and at the same time, a certain amount of waste stone materials will be generated. Therefore, operators need to sort the stone materials, re-sort the stone materials according to their sizes, and then reuse the stone materials, which better meets the concept of green buildings and saves construction costs.

[0003] In related technologies, when sorting crushed stones, a vibrating screen is usually used to vibrate the stone materials to complete the sorting of the stone materials; or the sand and gravel are separated by means of water washing to complete the sorting of the stone materials.

[0004] In view of the above related technologies, the vibrating screen method will cause the overall volume of the device to be relatively large and the separation effect to decline. The method of using water washing will cause a large shortage and waste of water resources, seriously affecting the economy. Utility Model Content

[0005] In order to be able to separate stone materials and ensure economy at the same time, this application provides a sand and gravel separation device.

[0006] This application provides a sand and gravel separation device, adopting the following technical solutions:

[0007] A sand and gravel separation device includes a filtering mechanism and a separation mechanism;

[0008] The filtering mechanism includes a filtering box and a reservoir. The filtering box is arranged obliquely downward along the traveling direction of the crushed stones. The top and bottom of the filtering box are respectively provided with a feed inlet and a discharge outlet, and a water outlet is provided at the end in the traveling direction of the sand and gravel. The water outlet is communicated with the inner cavity of the reservoir; a filter screen is fixedly connected inside the filtering box.

[0009] The separation mechanism includes an installation pipe. The installation pipe is located above the reservoir. The installation pipe is inclined upward along the traveling direction of the sand and gravel. The installation pipe passes through the discharge outlet and is fixedly connected to the filtering box. A sand outlet is provided at the top of the installation pipe in the vertical direction. A threaded piece is arranged along the long side direction in the inner cavity of the installation pipe, and the threaded piece is rotatably connected to the installation pipe.

[0010] By adopting the above technical solution, the setting of the filter box provides support for the installation of the filter screen. The filter screen can filter the sand and gravel. At the same time, the filter box is inclined, which enables the sand and gravel to slide downward, avoiding the accumulation of sand and gravel at the feed port. After the small-diameter sand and gravel pass through the filter screen, they can accumulate at the discharge port. The large-particle-size sand and gravel cannot pass through the filter screen and stay above the filter screen. The water flow can accelerate the flow rate of the fine sand and gravel to a certain extent and converge in the reservoir. Subsequently, the fine sand and gravel come into contact with the threaded pieces in the installation pipe, and the threaded pieces drive the fine sand and gravel to slide upward, taking the fine sand and gravel out of the installation pipe, thereby completing the separation of the sand and gravel. While being able to separate the sand and gravel, it avoids the waste of a large amount of water resources, improves the economic efficiency of the device, and facilitates the subsequent related operations of the operator.

[0011] Optionally, a blocking plate is provided at the water outlet, and the blocking plate is fixedly connected to the filter box.

[0012] By adopting the above technical solution, the setting of the blocking plate can block the larger-particle-size gravel above the filter screen, thereby preventing the large-particle-size sand and gravel from sliding out of the water outlet and falling into the reservoir, which is not convenient for the operator to collect accordingly.

[0013] Optionally, an observation port is provided at the top of the installation pipe.

[0014] By adopting the above technical solution, the setting of the observation port facilitates the operator to understand the rotation state of the threaded pieces and can also understand the amount of fine sand and gravel adhering to the threaded pieces to a certain extent, thereby understanding the effect of sand and gravel separation.

[0015] Optionally, the filtering mechanism further includes a fixing frame, the fixing frame is fixed to the ground, the fixing frame is fixedly connected with a plurality of fixing rods, and a shock-absorbing component is provided at the top of each fixing rod. The shock-absorbing component includes a fixing piece and a buffer piece. The fixing piece is fixedly connected to the filter box, one end of the buffer piece is fixedly connected to the fixing rod, and the other end is fixedly connected to the fixing piece.

[0016] By adopting the above technical solution, the setting of the fixing frame provides support for the installation of the fixing rods. The setting of the fixing rods provides support for the installation of the shock-absorbing components. The fixing piece can be used as a connection between the filter box and the elastic piece. The setting of the elastic piece can effectively reduce the impact of the sand and gravel on the filter box when the sand and gravel are put into the filter box, thereby protecting the filter box.

[0017] Optionally, the filtering mechanism further includes an observation component, the observation component includes a support platform and a climbing ladder. The top wall of the support platform is flush with the filter box, and the support platform is fixed beside the filter box. One end of the climbing ladder is fixedly connected to the support platform, and the other end is fixed to the ground.

[0018] By adopting the above technical solutions, the setting of the support platform facilitates the operator to understand the relevant structures inside the filter box and the sorting state, and then control the speed of sand and gravel feeding. The setting of the climbing ladder enables the operator to climb to the upper part of the support platform, increasing the convenience for the operator.

[0019] Optionally, a water pump is provided at the reservoir.

[0020] By adopting the above technical solutions, the setting of the water pump facilitates the operator to pump out the water in the reservoir and perform subsequent related operations, enabling the reuse of water resources and improving the overall economic effect.

[0021] Optionally, a scraping component is provided at the sand outlet of the installation pipe. The scraping component includes an installation rod and a scraping plate. One end of the installation rod is fixedly connected to the installation pipe, and the other end is fixedly connected to the scraping plate. The scraping plate abuts against the side wall of the threaded piece.

[0022] By adopting the above technical solutions, the setting of the connecting rod can fix the scraping plate to the side wall of the installation pipe, thereby completing the fixation of the scraping plate to the installation pipe. The scraping plate can abut against the threaded piece to scrape the fine sand adhered to the side wall of the scraping plate, enabling the sand to leave the threaded piece and fall into the sand outlet.

[0023] Optionally, the separation mechanism further includes a vibration motor, which is fixedly connected to the bottom wall of the filter box.

[0024] By adopting the above technical solutions, the vibration motor can cause the filter box to vibrate to a certain extent, thereby accelerating the filtering effect of the filter screen on the sand and gravel.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. By setting the filter box and the separation structure, the sand and gravel are filtered through the filter screen, and the fine sand and gravel are separated through the threaded piece to complete the separation operation of the sand and gravel;

[0027] 2. By setting the shock absorption component, the impact on the filter box when the sand and gravel are put into the filter box can be reduced;

[0028] 3. By setting the observation component, it is convenient for the operator to control the state of the relevant structures inside the filter box and the sand and gravel content. BRIEF DESCRIPTION OF THE DRAWINGS

[0050]

[0050] The implementation principle of Embodiment 1 is as follows: The operator first puts the sand and gravel and water together into the interior of the filter box 13 through the feed port 131. Subsequently, the sand and gravel are filtered under the action of the filter screen 15. The sand and gravel slide along the inclined direction of the filter box 13.

[0051]

[0051] The first motor 22 drives the threaded piece 24 to rotate, thereby driving the fine sand at the discharge port 132 and sliding upward until it falls into the reservoir 17 at the sand outlet 211, and is collected by the operator accordingly.

[0052] Embodiment 2

[0053]

[0053] The difference between this embodiment and Embodiment 1 is that under the action of gravity, the filtering effect of the sand and gravel is poor, and at the same time, part of the sand and gravel will adhere to the threaded piece 24 and cannot fall, thereby affecting the filtering effect of the sand and gravel.

[0055] Referring to Figure 4 , a vibration motor 18 is installed on the bottom wall of the filter box 13.

[0056] The implementation principle of Embodiment 2 is as follows: The threaded piece 24 rotates, so that the sand and gravel adhered to the threaded piece 24 come into contact with the scraping plate 262, and the scraping plate 262 makes the fine sand and gravel leave the threaded piece 24.

[0057] The vibration motor 18 improves the filtering effect of the filter screen 15 on the sand and gravel.
