Technical Field

[0001] The utility model relates to the technical field of calcium hydroxide production, in particular to a screening device with a multi-stage screening structure. Background Art

[0002] Calcium hydroxide is a white powdery solid with the chemical formula Ca(OH). It is commonly known as slaked lime or hydrated lime, and its aqueous solution is called clear limewater. Calcium hydroxide has the general properties of an alkali and is a strong base. Although it is a strong dibasic base, it is only slightly soluble in water. Calcium hydroxide has a wide range of industrial applications.

[0003] At present, when calcium hydroxide is produced and processed, most of the raw materials need to be screened to facilitate subsequent processing in different steps. However, most of the existing screening devices adopt a one-stage screening method, which results in the need for multi-stage screening of the raw materials. The intermediate filter screen needs to be frequently replaced during use to achieve multi-stage screening of the materials, which makes the device inconvenient to use and affects subsequent use.

[0021] In this embodiment, Figure 1 and Figure 2 As shown, support legs 11 are fixedly installed at the four corners of the lower end of the fixed base 1, and a slide 12 is fixedly installed inside the fixed base 1. This structure can support the entire device through the support legs 11 under the fixed base 1, and at the same time facilitate the subsequent docking of the collection device.

[0022] In this embodiment, Figure 1 and Figure 2 As shown, a fixing bar 14 is fixedly installed at the lower end of each mounting frame 13, and a reserved groove 15 is opened at the upper end of each mounting frame 13. Each mounting frame 13 and the fixed base 1 are superimposed on each other through the reserved groove 15 and the fixing bar 14. This structure can facilitate the docking and assembly of the mounting frames 13 by coordinating the reserved groove 15 opened above the mounting frame 13 with the fixing bar 14 installed at the bottom.

[0023] In this embodiment, Figure 1 and Figure 2 As shown, a sliding groove 17 is provided at the side end of each mounting frame 13, and a blocking plate 16 is fixedly installed on the left and right inner walls of each mounting frame 13. This structure can be supported by the blocking plate 16 and the sliding groove 17 is grooved, which is convenient for the subsequent installation and use of the sliding base plate 2, filter plate 3 and other parts.

[0024] In this embodiment, Figure 1 and Figure 3As shown, each sliding base plate 2 is slidably installed inside the mounting frame 13 by cooperating with the blocking plate 16 and the sliding groove 17. A rotating shaft 24 is rotatably installed inside each sliding base plate 2, and a rotating motor 25 is rotatably installed on the side end of each rotating shaft 24. A toggle ring 23 is sleeved on the outer surface of each rotating shaft 24. This structure can drive the rotating shaft 24 to rotate by the rotating motor 25 and drive the toggle ring 23 to rotate, so as to facilitate the subsequent vibration of the filter plate 3.

[0025] In this embodiment, Figure 1 and Figure 3 As shown, a connecting plate 21 is fixedly installed on the upper end of each sliding base plate 2, and a fixed handle 22 is fixedly installed on the side end of each sliding base plate 2. This structure can facilitate docking with the filter plate 3 through the connecting plate 21 installed on the side end of the sliding base plate 2, and then cooperate with the fixed handle 22 to facilitate pulling the whole.

[0026] In this embodiment, Figure 1 、 Figure 3 and Figure 4 As shown, a rotating plate 31 is fixedly installed on the side end of each filter plate 3, and a rotating column 32 is fixedly installed on the left and right sides of each rotating plate 31. Each filter plate 3 is rotatably installed above the sliding bottom plate 2 through the rotating plate 31, the rotating column 32 and the connecting plate 21. This structure can facilitate the use of the filter plate 3 by cooperating with the connecting plate 21 through the rotating plate 31 and the rotating column 32 installed on the side end of the filter plate 3.

[0027] The use method and advantages of the utility model: The screening device with a multi-stage screening structure works as follows when in use:

[0028] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, first, when using, the user places the device on a horizontal surface, picks up the fixed base 1, installs the support legs 11 at the four corners below the fixed base 1, installs the slide 12 inside the fixed base 1, then picks up the installation frame 13, installs the fixing bar 14 below the installation frame 13, installs the blocking plate 16 inside the installation frame 13, and then assembles the three installation frames 13, and installs them along the lower fixing bar 14 and the reserved groove 15 opened above the installation frame 13, then stacks the three installation frames 13, and then installs the fixing bar 14 installed below the lowest installation frame 13 and the groove above the fixed base 1, and then the user picks up the sliding base 2 , install the rotating shaft 24 inside the sliding base plate 2, install the rotating motor 25 on the side end of the rotating shaft 24, and sleeve the toggle ring 23 on the outer surface of the rotating shaft 24, then install the fixed handle 22 on the side end of the sliding base plate 2, install the connecting plate 21 above the sliding base plate 2, and then pick up the filter plate 3, install the rotating plate 31 on the side end of the filter plate 3, and install the rotating columns 32 on the left and right sides of the rotating plate 31. Then, the assembled filter plate 3 is installed above the sliding base plate 2 along the rotating plate 31, the rotating column 32 and the connecting plate 21, and then three groups of sliding base plates 2 and filter plate 3 parts are assembled, and filter screens 33 with different pore sizes are installed inside each filter plate 3, and then each assembled sliding base plate 2 is assembled. The filter plate 3 is connected to the three mounting frames 13 in sequence from top to bottom along the pore size of the filter screen 33, and is installed through the sliding groove 17 opened at the side end of each mounting frame 13 and the blocking plate 16 installed inside. The filter screen 33 with the largest pore is installed in the uppermost mounting frame 13. When the user needs to use the device, the user pours the material to be screened from the top into the device, and then starts all the rotating motors 25 inside the device. At the same time, a collection box is placed in the pore below the fixed base 1. As the rotating motor 25 starts, the rotating shaft 24 is driven to rotate, thereby driving the dial ring 23 to rotate. When the dial ring 23 rotates, it cooperates with the protrusions on both sides to adjust the filter plate 3. One side is tilted to make the filter plate 3 vibrate inside the device, and then the material falling on the filter screen 33 will be continuously screened under the vibration of the filter plate 3, and the material smaller than the pore size will quickly fall onto the filter screen 33 below. The above operation is performed until it completely passes through all the filter screens 33. At this time, the material will fall on the landslide 12 for concentration, and then cooperate with the collection device under the fixed base 1 for collection. When the user needs to collect the residual material inside the device, the user pulls the fixed handle 22 from the side end, and the fixed handle 22 drives the sliding bottom plate 2 and the filter plate 3 to slide out from the inside of the device, thereby facilitating the subsequent cleaning of the residual material on the filter plate 3.

Persons skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
