Description

Technical Field

[0001] This application relates to the technical field of chemical industry, and in particular to a discharge port switching device for a scraper discharge centrifuge. Background Technology

[0002] The scraper discharge centrifuge can automatically perform processes such as feeding, separation, washing, dewatering, liquid discharge, unloading, and screen washing at full speed. It features a novel structure, stable operation, high degree of automation, low labor intensity, large production capacity, good washing effect, and low moisture content in the filter cake.

[0003] A scraper discharge centrifuge discharge port switching device is disclosed on the Chinese Patent Network (publication number: CN217313930U). It includes a hopper, a hopper support, and a power mechanism. The top of the hopper is open, and the bottom of the hopper is inclined to form a guide slope. A first discharge port is formed on one side of the end of the guide slope, and a second discharge port is formed on the opposite side of the first discharge port. First connecting rods are respectively arranged in the middle of the other two sides of the hopper, and second connecting rods are respectively arranged on the other two sides of the hopper near the first discharge port. The two second connecting rods are connected by a first rotating rod. The hopper support is fixedly connected to the outer wall of the scraper discharge centrifuge where the discharge port is located, and is used to support the hopper and the power mechanism. The hopper support is hinged to the hopper at the extended end of the first connecting rod, and the power mechanism is hinged to the hopper at the middle of the first rotating rod, providing power for the rotation of the hopper.

[0004] The following problems exist in this solution: By adjusting the angle of the distribution hopper to switch the discharge, the material is discharged from both ends of the distribution hopper into different collection chambers for collection. However, after one type of material is discharged, the inside of the distribution hopper is not cleaned, which will cause residual material to be discharged into the other collection chamber when switching the discharge, resulting in poor material distribution effect. Therefore, there are certain drawbacks.

[0005] Therefore, in order to solve the above problems, this application provides a scraper discharge centrifuge outlet switching device. Utility Model Content

[0009] Preferably, the top of the fixing plate is provided with a sliding groove, a slider is installed in the sliding groove at the top of the fixing plate, and the top of the slider is connected to the bottom of the rack.

[0010] Preferably, one end of the rotating rod passes through one of the vertical plates and a gear is installed thereon. The gear meshes with the rack. The outer ring surface of the rotating rod is fixedly connected to the two support seats. When the rotating rod rotates and drives the material distribution hopper to rotate, it does not interfere with the two vertical plates.

[0011] Preferably, the two ends of the scraper are slidably connected to the outer ring surfaces of the two slide bars, and the outer side of the scraper is in contact with the bottom and inner side walls of the hopper.

[0012] Preferably, each of the fixed blocks is equipped with a telescopic rod on its top, a return spring is installed on the outer ring surface of the telescopic rod, a horizontal plate is installed on the top of the telescopic rod, a limit rod is installed at the bottom of the horizontal plate away from the telescopic rod, and limit holes are symmetrically opened at both ends of the top of the scraper, and the outer ring surface dimension of the limit rod is adapted to the inner sidewall dimension of the limit hole.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] This scraper discharge centrifuge discharge port switching device uses a rack sliding on the top of a fixed plate to drive a gear to rotate. The gear's rotation drives a rotating rod, which in turn drives the distribution hopper to rotate via two sets of support seats. This allows for angle adjustment of the distribution hopper, facilitating material discharge from the lower end by tilting the hopper. The device also pushes a scraper to slide on two sliding rods, scraping away any remaining sticky material inside the distribution hopper. This prevents residual material from flowing into the other collection chamber during discharge switching, which would otherwise result in poor material distribution. A limiting rod is inserted into a limiting hole to fix the scraper at one end of the distribution hopper, ensuring that the scraper remains at the higher tilt end when the hopper is tilted, preventing material from flowing out from the higher end and causing waste.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.

[0024] A scraper discharge centrifuge outlet switching device, as described in the following reference. Figure 1 - Figure 6 The system includes a base 1, a scraper discharge centrifuge 2 mounted on one top end of the base 1, a discharge hopper 3 mounted on the outside of the scraper discharge centrifuge 2, support frames 4 symmetrically mounted on both ends of the scraper discharge centrifuge 2 below the discharge hopper 3, a reinforcing plate 5 mounted on the bottom of the support frame 4, a support plate 6 mounted between the outer sides of the support frame 4, upright plates 7 symmetrically mounted on both ends of the top of the support plate 6, a rotating rod 8 mounted between the outer sides of the upright plates 7, support seats 9 symmetrically mounted on both ends of the rotating rod 8, a distribution hopper 10 mounted on the top of the support seats 9, fixing blocks 11 symmetrically mounted on both sides of the outer ends of the distribution hopper 10, a sliding rod 12 mounted between the outer sides of the fixing blocks 11, and a scraper 13 mounted between the outer sides of the sliding rod 12 and inside the distribution hopper 10.

[0025] Reference Figure 1 - Figure 4 One of the support frames 4 has a fixed plate 14 installed on its top, and a rack 15 installed on its top. An electric telescopic rod 16 is installed on the top of the support frame 4 and close to the fixed plate 14. A connecting plate 17 is installed on the movable end of the electric telescopic rod 16, and one end of the connecting plate 17 is connected to one end of the rack 15. The extension or retraction of the electric telescopic rod 16 drives the connecting plate 17 to move. When the connecting plate 17 moves, it simultaneously drives the rack 15 to move on the top of the fixed plate 14. A sliding groove is provided on the top of the fixed plate 14, and a slider 18 is installed in the sliding groove on the top of the fixed plate 14. The top of the slider 18 is connected to the bottom of the rack 15. When the rack 15 moves, it simultaneously drives the slider 18 to slide in the sliding groove on the top of the fixed plate 14, thereby increasing the stability of the rack 15 moving on the top of the fixed plate 14.

[0026] Reference Figure 1 - Figure 4 One end of the rotating rod 8 passes through one of the vertical plates 7 and a gear 19 is installed thereon. The gear 19 meshes with the rack 15. The rack 15 slides on the top of the fixed plate 14, thereby driving the gear 19 to rotate. When the gear 19 rotates, it drives the rotating rod 8 to rotate, which in turn drives the distribution hopper 10 to rotate through the two sets of support seats 9. This allows for angle adjustment of the distribution hopper 10, making it easier to tilt the distribution hopper 10 so that the material can be discharged from the lower end, thus achieving switching of discharge. The outer ring surface of the rotating rod 8 is fixedly connected to the two support seats 9, and the rotating rod 8 does not interfere with the two vertical plates 7 when it drives the distribution hopper 10 to rotate, thereby avoiding the situation where the distribution hopper 10 gets stuck during rotation.

[0027] Reference Figure 5The two ends of the scraper 13 are slidably connected to the outer ring surfaces of the two slide bars 12, and the outside of the scraper 13 is in contact with the bottom and the inner side walls of the hopper 10. By pushing the scraper 13, the scraper 13 is driven to slide on the two slide bars 12, thereby scraping off and discharging the residual sticky material inside the hopper 10, so as to avoid the residual material being discharged into another collection chamber when the hopper 10 switches to discharge, which would result in poor material distribution.

[0028] Reference Figure 5 - Figure 6 Each of the fixed blocks 11 has a telescopic rod 20 installed on its top. A return spring 21 is installed on the outer ring surface of the telescopic rod 20. A horizontal plate 22 is installed on the top of the telescopic rod 20. A limit rod 23 is installed at the bottom end of the horizontal plate 22 away from the telescopic rod 20. By pulling the horizontal plate 22 upward, the telescopic rod 20 can be extended and the return spring 21 can be stretched. Limit holes 1301 are symmetrically opened at both ends of the top of the scraper 13. The outer ring surface dimension of the limit rod 23 is consistent with the inner wall dimension of the limit hole 1301. When the scraper 13 is in a matching position, it scrapes away the remaining material inside the distribution hopper 10 and moves to one end of the distribution hopper 10. At this time, the limiting rod 23 is located directly below the limiting hole 1301. Then, the horizontal plate 22 is released, and the restriction of the reset spring 21 is released, which drives the limiting rod 23 to enter the interior of the limiting hole 1301, thereby fixing the scraper 13 to one end of the distribution hopper 10. When the distribution hopper 10 is tilted, the scraper 13 is always at the higher tilt end, which prevents the material from flowing out from the higher end and causing waste.

[0029] Reference Figure 1 A material distribution bin 24 is installed on the top of the base 1 and below the material distribution hopper 10. The material distribution bin 24 has two symmetrically arranged storage chambers 2401 inside, and the two storage chambers 2401 are located directly below the two ends of the material distribution hopper 10. By dividing the material distribution bin 24 into two storage chambers 2401, it is convenient to collect two different materials when the material distribution hopper 10 switches discharge, without having to change them during the collection process, making the operation more convenient.

[0030] The implementation principle of the scraper discharge centrifuge outlet switching device in this application embodiment is as follows: When switching the outlet of the scraper discharge centrifuge, the electric telescopic rod 16 is preferably of type LX600. The electric telescopic rod 16 is electrically connected to an external power source through a switch. The electric telescopic rod 16 is activated by the switch, extending or retracting to move the connecting plate 17. When the connecting plate 17 moves, it simultaneously drives the rack 15 to move on the top of the fixed plate 14. When the rack 15 moves, it simultaneously drives the slider 18 to slide in the groove on the top of the fixed plate 14, thereby increasing the stability of the rack 15's movement on the top of the fixed plate 14. The sliding of the rack 15 on the top of the fixed plate 14 drives the gear 19 to rotate. When the gear 19 rotates, it drives the rotating rod 8 to rotate, which in turn drives the distribution hopper 10 to rotate through the two sets of support seats 9. This allows for angle adjustment of the distribution hopper 10, facilitating material discharge from the lower end by tilting the distribution hopper 10, thus achieving the switching of discharge. When switching is required after the first round of discharge, the device is pushed... The scraper 13 slides on the two sliding rods 12, thereby scraping away and discharging the residual sticky material inside the distributing hopper 10. This prevents residual material from being discharged into another collection chamber when the distributing hopper 10 switches discharge points, which would result in poor material distribution. By pulling the horizontal plate 22 upward, the telescopic rod 20 can be extended and the return spring 21 can be stretched. After scraping away the residual material inside the distributing hopper 10, the scraper 13 moves to one end of the distributing hopper 10, and at this time, the limiting rod 23 is located directly below the limiting hole 1301. Then, the horizontal plate 22 is released, and the restriction of the reset spring 21 is released, which drives the limit rod 23 to enter the interior of the limit hole 1301, thereby fixing the scraper 13 to one end of the distribution hopper 10. When the distribution hopper 10 is tilted, the scraper 13 is always at the higher tilt end, avoiding material from flowing out from the higher end and causing waste. In addition, by dividing the distribution bin 24 into two storage chambers 2401, it is convenient to collect two different materials when the distribution hopper 10 switches discharge, without the need to change them during the collection process, making the operation more convenient.
