Description

Technical Field

[0001] This utility model relates to the field of hydrocyclones, and more particularly to a multi-stage hydrocyclone. Background Technology

[0002] As mechanization increases and mining depth increases, the quality of raw coal deteriorates, and the content of pulverized coal in the coal being processed increases. Coal slime is first classified using hydrocyclones, which typically include components such as a cylinder, a cone, a feed pipe, an overflow pipe, and a discharge pipe.

[0003] Most existing multistage hydrocyclones are of the split type. Split-type multistage hydrocyclones facilitate later maintenance. The split-type multistage hydrocyclone includes an inlet section and an outlet section. Currently, the installation of multistage hydrocyclones is done manually. First, the outlet section with its base is placed in the installation position. Then, the inlet section is moved above the outlet section by personnel, and multiple fastening bolts are inserted and tightened in sequence to fix the inlet and outlet sections. However, when fixing the inlet section to the outlet section, the inlet section needs to be positioned. During this process, the flange of the inlet section is prone to lateral deviation. Personnel often need to tighten the fastening bolts in a diagonal sequence to ensure that the inlet section does not deviate during tightening. This makes the tightening process time-consuming, increases the labor intensity of personnel, and requires skilled personnel. Utility Model Content

[0016] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0017] like Figure 1 As shown in the figure, a multi-stage cyclone separator according to an embodiment of the present invention includes... The discharge cylinder section 1000, the inlet cylinder section 2000, the positioning assembly 3000, and the column pin; The discharge cylinder 1000 includes a discharge column 1100, a sinking cone 1200 and a support column 1300. One end of the discharge column 1100 is provided with a first flange 1400. Multiple pin holes 1410 and multiple mounting holes 1420 are opened on the circumference of the first flange 1400. The feed cylinder 2000 is located above the discharge cylinder 1000. The feed cylinder 2000 includes a feed cylinder 2100, a feed pipe 2200, and an overflow pipe 2300. A second flange 2400 is provided at one end of the feed cylinder 2100. Multiple pin holes 1410 and multiple positioning holes 2410 are opened on the circumference of the second flange 2400. The center of the mounting hole 1420 of the first flange 1400 and the center of the positioning hole 2410 of the second flange 2400 are both located on the same axis. Multiple positioning components 3000 are arranged circumferentially at the bottom of the first flange 1400. Each positioning component 3000 includes a pin cylinder 3100, a fixing member 3200, a connecting column 3300, a lateral moving member 3400, and an auxiliary lifting member 3500. The pin cylinder 3100 is located below the pin hole 1410 of the first flange 1400, and the fixing member 3200 is located below the mounting hole 1420 of the first flange 1400. A connecting column 3300 is provided between the fixing member 3200 and the pin cylinder 3100. The connecting column 3300 has a hollow cavity. The pin cylinder 3100 is provided with a hollow pin cavity 3110. The hollow cavity of the connecting column 3300 is connected to the hollow pin cavity 3110 and the inner cavity of the fixing member 3200. One end of the transverse member 3400 slides in the inner cavity of the fixing member 3200, and the other end of the transverse member 3400 passes through the hollow cavity of the connecting column 3300 and extends into the hollow pin cavity 3110. One end of the auxiliary lifting member 3500 extends into the inner cavity of the fixing member 3200 and cooperates with the transverse member 3400. The other end of the auxiliary lifting member 3500 passes through the fixing member 3200 and cooperates with the positioning hole 2410. The pin shaft 4000 passes through the pin hole 1410 of the first flange 1400, the pin hole of the second flange 2400, and the hollow pin cavity 3110 of the pin cylinder 3100. The other end of the pin shaft 4000 is engaged with the other end of the transverse component 3400. When installing the multi-stage hydrocyclone of this utility model, the user first needs to install multiple positioning components 3000 onto the bottom of the first flange 1400 of the discharge cylinder 1000, ensuring that the fixing component 3200 is located below the mounting hole 1420 and the pin cylinder 3100 is located below the pin hole 1410. After installing the multiple positioning components 3000, the discharge cylinder 1000 is moved to the installation position, and then the feed cylinder 2100 is placed above the discharge cylinder 1000, ensuring that the positioning hole 2410 of the second flange 2400 of the feed cylinder 2100 coincides with the mounting hole 1420 of the first flange 1400. At this time, the fastening hole 1430 of the first flange 1400 coincides with the fastening hole 1430 of the second flange 2400, and the pin hole 1410 of the first flange 1400 coincides with the pin hole 1410 of the second flange 2400. At this point, the user inserts multiple pins 4000 into the pin holes 1410 of the first flange 1400 and the second flange 2400 in sequence. The other end of the pin 4000 pushes the transverse component 3400, causing the transverse component 3400 to slide away from the pin cylinder 3100 within the fixing component 3200. At this time, the auxiliary lifting component 3500 slides through the transverse component 3400, changing from its initial position to a lifting state, so that the other end of the auxiliary lifting component 3500 extends into the positioning hole 2410 of the second flange 2400, thereby fixing the second flange 2400 and preventing it from wobbling left and right. Then, the user inserts multiple fastening bolts into the fastening holes 1430 of the first flange 1400 and the second flange 2400 in sequence and tightens the fastening bolts. Because the auxiliary lifting component 3500 rises and engages with the positioning hole 2410, the user does not need to tighten them in a diagonal order, thus saving overall installation time. When disassembling the feed cylinder 2100, after removing the fastening bolts, the column pin 4000 is then removed. At this time, the other end of the column pin 4000 no longer restricts the transverse movement component 3400, and the transverse movement component 3400 returns to its initial position, causing the auxiliary lifting component 3500 to return to its initial position along with the transverse movement component 3400. Thus, the second flange 2400 is no longer restricted, and it awaits the next installation of the feed cylinder body for auxiliary positioning.

[0018] Furthermore, as shown in the figure, the other end of the material drop column 1100 is connected to the large-diameter end of the material sinking cone 1200, and the small-diameter end of the material sinking cone 1200 has a material sinking port 1210. Multiple support columns 1300 are arranged on the bottom circumference of the first flange 1400. The support columns 1300 are used to support the entire device and ensure the stability of the entire device during operation.

[0019] Further, as shown in the figure, an overflow pipe 2300 is provided through the other end of the feed cylinder 2100. One end of the overflow pipe 2300 extends into the feed cylinder 2100. The feed pipe 2200 is tangent to the side wall of the other end of the feed cylinder 2100. One end of the feed pipe 2200 extends into the inner cavity of the other end of the feed cylinder 2100.

[0020] Further, as shown in the figure, the fixing member 3200 includes a fixing housing 3210 and a mounting cylinder 3220. The mounting cylinder 3220 is disposed on the top of the fixing housing 3210 and is sleeved in the mounting hole 1420. A lifting cylinder cavity 3221 is provided at the center of the mounting cylinder 3220. The lifting cylinder cavity 3221 communicates with the inner cavity of the fixing housing 3210. A sliding port 3211 is opened at one end of the fixing housing 3210, and a movable hole 3213 is opened at the other end of the fixing housing 3210. A sliding groove 3212 is opened at the bottom of the inner cavity of the fixing housing 3210. The diameter of the mounting cylinder 3220 is the same as the diameter of the mounting hole 1420, ensuring that the mounting cylinder 3220 fits into the mounting hole 1420. The diameter of the lifting cavity 3221 opened in the mounting cylinder 3220 is the same as the diameter of the positioning hole 2410. The sliding groove 3212 is used to assist and limit the sliding of the transverse member 3400. When the transverse member 3400 is at the maximum stroke position, one end of the transverse member 3400 extends out of the sliding port 3211.

[0021] Further, as shown in the figure, the movable hole 3213 communicates with the hollow cavity of the connecting post 3300, and a sliding hole 3120 is provided on the outer side wall of the bottom of the pin cylinder 3100. The sliding hole 3120 communicates with the pin cavity 3110 and the hollow cavity of the connecting post 3300. The inner cavity of the fixed housing 3210 communicates with the pin cavity 3110 through the movable hole 3213, the hollow cavity of the connecting post 3300, and the sliding hole 3120. This allows the other end of the transverse member 3400 to engage with the pin shaft 4000 provided in the pin cavity 3110 through the sliding hole 3120, the hollow cavity of the connecting post 3300, and the sliding hole 3120.

[0022] Further, as shown in the figure, the transverse component 3400 includes a transverse slider 3410, a transverse spring 3430, and a transverse column 3420. The transverse slider 3410 is slidably disposed in the sliding groove 3212. A lifting protrusion 3411 is provided at the top end of the transverse slider 3410 near the movable hole 3213. A lifting ramp 3412 is provided between the lifting protrusion 3411 and the top surface of the transverse slider 3410. The transverse column 3420 is provided at the end of the transverse slider 3410 near the movable hole 3213. The other end of the transverse column 3420 extends into the pin cavity 3110 through the movable hole 3213, the hollow cavity of the connecting column 3300, and the sliding hole 3120. The other end of the transverse column 3420 is engaged with the pin shaft 4000 in the pin cavity 3110. The transverse spring 3430 is sleeved on one end of the transverse column 3420. One end of the transverse spring 3430 is connected to one end of the transverse slider 3410, and the other end of the transverse spring 3430 is connected to the inner wall of the movable hole 3213 of the fixed housing 3210. When the transverse slider 3410 is in its initial position, the other end of the transverse column 3420 extends into the pin cavity 3110. When the pin is inserted into the pin cavity 3110 and the other end of the pin is descending, it continuously pushes the transverse column 3420 out of the pin cavity 3110, thereby driving the transverse slider 3410 to move towards the sliding port 3211. At the same time, the transverse spring 3430 is gradually stretched, so that the auxiliary lifting member 3500 reaches the lifting protrusion 3411 of the transverse slider 3410, raising the height of the auxiliary lifting member 3500. Then, the auxiliary lifting member 3500 cooperates with the positioning hole 2410. When the pin shaft 4000 exits the pin cavity 3110, the transverse spring 3430 will return to its initial state, thereby dragging the transverse slider 3410 to move towards the movable hole 3213, so that the other end of the transverse column 3420 re-extends into the pin cavity 3110.

[0023] Preferably, as shown in the figure, the other end of the pin 4000 is conical and the other end of the transverse column 3420 is hemispherical, so that when the other end of the pin 4000 descends, it better assists the transverse column 3420 in moving.

[0024] Further, as shown in the figure, the auxiliary lifting component 3500 includes a lifting column 3510 and an auxiliary wheel set 3520. One end of the lifting column 3510 is sleeved in the lifting cylinder cavity 3221. The diameter of the lifting column 3510 is the same as the diameter of the positioning hole 2410. One end of the lifting column 3510 is engaged with the positioning hole 2410. The other end of the lifting column 3510 is provided with the auxiliary wheel set 3520. The auxiliary wheels are engaged with the top of the transverse slider 3410, the lifting ramp 3412, and the top of the lifting protrusion 3411, respectively. The lifting column 3510 is fitted inside the lifting cylinder cavity 3221, restricting the lifting column 3510 to move up and down only within the lifting cylinder cavity 3221. When the transverse slider 3410 is in its initial position, the auxiliary wheel assembly 3520 at the other end of the lifting column 3510 is located on the top surface of the transverse slider 3410 near the sliding opening 3211. As the transverse slider 3410 gradually moves, the auxiliary wheel assembly 3520 gradually passes through the lifting ramp. When 3412 reaches the lifting protrusion 3411, there is a height difference between the top of the lifting protrusion 3411 and the top of the transverse slider 3410. Therefore, as the lifting slide 3412 and the lifting protrusion 3411 rise, one end of the lifting column 3510 protrudes out of the lifting cylinder cavity 3221. Conversely, when the transverse slider 3410 returns to the initial position, the lifting column 3510 will return to the initial position, so that one end of the lifting column 3510 returns to the lifting cylinder cavity 3221.

[0025] Preferably, as shown in the figure, a connecting boss is provided on the top of the fixed housing 3210 and the pin cylinder 3100 to fix the first flange 1400. Both the connecting boss and the first flange 1400 are provided with connecting threaded holes, so that the user can screw the bolts into the connecting threaded holes to fix the positioning component 3000 to the bottom of the first flange 1400. The above-mentioned mounting bolts are existing technology, so they will not be described in detail.
