Abstract

This invention relates to a stirring impeller structure for direct starting of fluid in a settling tank, comprising: a main shaft; a first impeller fixedly connected to the main shaft and having a first toothed disc at its end; a transmission sleeve slidably mounted on the main shaft and having a second toothed disc at its end; a second impeller slidably connected to the transmission sleeve; and a clutch mechanism. When the device agitates the fluid in the settling tank, the main shaft rotates, and torque is transmitted to the first impeller. If the external resistance torque exceeds a certain value, the clutch mechanism separates the first and second toothed discs, and the torque only drives the first impeller to rotate, agitating the fluid in the settling tank first. When the external resistance torque is less than the certain value, the clutch mechanism engages the first and second toothed discs, and the torque of the main shaft is sequentially transmitted to the first toothed disc, the second toothed disc, the transmission sleeve, and the second impeller, driving the first and second impellers to rotate synchronously. Under the synchronous action of the first and second impellers, the agitation of the fluid in the settling tank is completed.

Description

Technical Field

[0001] This invention relates to stirring structures, particularly stirring paddle structures for direct agitation of fluid in settling tanks. Background Technology

[0002] During the process of stirring the solution, some solvent will settle at the bottom of the container. This part of the medium is called settling fluid, such as mud and sand settling at the bottom of water.

[0003] During the stirring process of the settling tank fluid, the main shaft needs to rotate to provide a large torque to agitate the fluid. Therefore, a high-power motor is often required when configuring the power mechanism. However, when the solvent is agitated, the power output of the motor is small and stable, which results in redundancy in the motor power and increases the cost accordingly.

[0004] In addition, during operation, the blades became stuck in the fluid in the settling tank and could not continue to rotate.

[0005] In summary, how to achieve direct initiation of fluid in the settling tank has become an urgent problem for researchers in this field. Summary of the Invention

[0006] The technical problem to be solved by this invention is: how to achieve direct initiation of fluid in a settling tank;

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] This invention relates to a stirring impeller structure for direct fluid agitation in a settling tank, comprising: a main shaft; a first impeller fixedly connected to the main shaft and having a first toothed disc at its end; a transmission sleeve slidably mounted on the main shaft and having a second toothed disc at its end; a second impeller slidably connected to the transmission sleeve; and a clutch mechanism, wherein the transmission sleeve moves linearly relative to the main shaft, engaging the first and second toothed discs and sequentially transmitting the torque of the main shaft to the first and second toothed discs, the transmission sleeve, and the second impeller, driving the first and second impellers to rotate synchronously; or separating the first and second toothed discs, driving only the first impeller to rotate.

[0009] In this design, the area of ​​the first blade is smaller than that of the second blade, so the resistance it experiences in a liquid containing solid particle sediment is less than that of the second blade.

[0010] When this device agitates the fluid in the settling tank, the main shaft rotates, and the torque is transmitted to the first blade. If the external resistance torque exceeds the limit value, the clutch mechanism separates the first and second sprockets, and the torque only drives the first blade to rotate, agitating the fluid in the settling tank first. When the external resistance torque is less than the limit value, the clutch mechanism engages the first and second sprockets, and the torque of the main shaft is sequentially transmitted to the first sprocket, the second sprocket, the transmission sleeve, and the second blade, driving the first and second blades to rotate synchronously. Under the synchronous action of the first and second blades, the agitation of the fluid in the settling tank is completed.

[0011] In addition, when the second blade is stuck by solid particles in the settling tank fluid, the second blade stops rotating. The solid particles stuck by the second blade are stirred by rotating the first blade, which facilitates the continued rotation of the second blade.

[0012] To illustrate the specific structure of the clutch mechanism, the present invention employs a clutch mechanism comprising: a steel ball, which is embedded in a semi-circular groove formed on the end faces of the first and second cranks; an elastic element, which is sleeved on the transmission sleeve and located within the cavity formed by the second blade and the transmission sleeve, one end of the elastic element abutting against the bottom of the cavity and the other end abutting against the second crank; when the elastic element is in its original length state, the steel ball is positioned within the semi-circular groove formed on the end faces of the first and second cranks.

[0013] Under the action of the elastic element, the steel ball is placed in the semi-circular grooves opened on the end faces of the first and second toothed plates. At this time, if the resistance of the trough fluid is greater than the torque of the second blade, only the first blade rotates, the steel ball disengages from the semi-circular groove of the second pressure plate, the first and second toothed plates separate, the spring is compressed, and the torque will not be transmitted to the second blade. The first blade rotates, agitating the trough fluid, and the resistance of the trough fluid gradually decreases. When the elastic element returns to its original length, the steel ball is placed in the semi-circular grooves opened on the end faces of the first and second toothed plates. The second blade and the first blade continue to agitate the trough fluid by rotating.

[0014] In other words, the main shaft outputs torque, which is transmitted to the first blade and the first gear plate. The first blade and the second blade work together to transmit torque, and the torque of the second gear plate is transmitted to the second blade. During operation, if the external resistance torque exceeds the limit value, the elastic element is compressed, the steel ball slips against the semi-circular groove on the second pressure plate, and the second blade stops rotating. The maximum torque that can be transmitted is determined by the relationship between the clamping force of the elastic element on the second pressure plate and the torque.

[0015] To illustrate how the main shaft and the first blade are fitted and fixedly connected, the present invention uses a key and a groove to connect the main shaft and the first blade.

[0016] In this way, the main shaft and the first blade are connected by a key and a groove, and the torque can be transmitted from the main shaft to the first blade.

[0017] To illustrate the connection between the second blade and the transmission sleeve, the present invention uses a sliding groove and a flat key to connect the second blade and the transmission sleeve.

[0018] The second blade and the transmission sleeve are connected by a slide groove and a flat key. When the transmission sleeve moves axially relative to the main shaft, the transmission sleeve also moves axially relative to the second blade under the cooperation of the slide groove and the slider.

[0019] In order to restrict the axial fixed connection between the first blade, the second blade, and the main shaft, the present invention adopts a limiting plate at the end of the main shaft, the limiting plate abutting against the end of the second blade to restrict the axial movement of the first blade and the second blade;

[0020] The axial movement of the first and second blades relative to the main shaft is restricted by the flat key and the limiting plate.

[0021] The beneficial effects of this invention are as follows: This invention is a stirring paddle structure for direct starting of the settling tank fluid. When this device agitates the settling tank fluid, the main shaft rotates, and the torque is transmitted to the first paddle. If the external resistance torque exceeds a certain value, the clutch mechanism separates the first and second discs, and the torque only drives the first paddle to rotate, thus agitating the settling tank fluid first. When the external resistance torque is less than the certain value, the clutch mechanism engages the first and second discs. At this time, the torque of the main shaft is sequentially transmitted to the first disc, the second disc, the transmission sleeve, and the second paddle, driving the first and second paddles to rotate synchronously. Under the synchronous action of the first and second paddles, the agitation of the settling tank fluid is completed. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] like Figure 1-4 As shown, the present invention is a stirring impeller structure for direct fluid agitation in a settling tank, comprising: a main shaft 1; a first impeller 2, which is fixedly connected to the main shaft 1 and has a first toothed disc 3 at its end; a transmission sleeve 4, which is slidably sleeved on the main shaft 1 and has a second toothed disc 5 at its end; a second impeller 6, which is slidably sleeved and connected to the transmission sleeve 4; and a clutch mechanism, wherein the transmission sleeve 4 moves linearly relative to the main shaft 1, engaging the first toothed disc 3 and the second toothed disc 5, and sequentially transmitting the torque of the main shaft 1 to the first toothed disc 3, the second toothed disc 5, the transmission sleeve 4, and the second impeller 6, driving the first impeller 2 and the second impeller 6 to rotate synchronously; or separating the first toothed disc 3 and the second toothed disc 5, driving only the first impeller 2 to rotate;

[0030] In this design, the area of ​​the first blade is smaller than that of the second blade, so that the resistance experienced by the first blade during agitation is less than that experienced by the second blade.

[0031] When this device agitates the fluid in the settling tank, the main shaft rotates, and the torque is transmitted to the first blade. If the external resistance torque exceeds the limit value, the clutch mechanism separates the first and second sprockets, and the torque only drives the first blade to rotate, agitating the fluid in the settling tank first. When the external resistance torque is less than the limit value, the clutch mechanism engages the first and second sprockets, and the torque of the main shaft is sequentially transmitted to the first sprocket, the second sprocket, the transmission sleeve, and the second blade, driving the first and second blades to rotate synchronously. Under the synchronous action of the first and second blades, the agitation of the fluid in the settling tank is completed.

[0032] In addition, when the second blade is stuck by solid particles in the settling tank fluid, the second blade stops rotating. The solid particles stuck by the second blade are stirred by rotating the first blade, which facilitates the continued rotation of the second blade.

[0033] like Figure 1-4 As shown, to illustrate the specific structure of the clutch mechanism, the present invention employs a clutch mechanism comprising: a steel ball 7, which is embedded in a semi-circular groove 8 formed on the end faces of the first and second cranks; an elastic element 9, which is sleeved on the transmission sleeve 4 and located in the cavity formed by the second blade 6 and the transmission sleeve 4, one end of the elastic element 9 abutting against the bottom of the cavity, and the other end abutting against the second crank 5; when the elastic element 9 is in its original length state, the steel ball 7 is placed in the semi-circular groove 8 formed on the end faces of the first and second cranks.

[0034] Under the action of the elastic element, the steel ball is placed in the semi-circular grooves opened on the end faces of the first and second toothed plates. At this time, if the resistance of the trough fluid is greater than the torque of the second blade, only the first blade rotates, the steel ball disengages from the semi-circular groove of the second pressure plate, the first and second toothed plates separate, the spring is compressed, and the torque will not be transmitted to the second blade. The first blade rotates, agitating the trough fluid, and the resistance of the trough fluid gradually decreases. When the elastic element returns to its original length, the steel ball is placed in the semi-circular grooves opened on the end faces of the first and second toothed plates. The second blade and the first blade continue to agitate the trough fluid by rotating.

[0035] In other words, the main shaft outputs torque, which is transmitted to the first blade and the first gear plate. The first blade and the second blade work together to transmit torque, and the torque of the second gear plate is transmitted to the second blade. During operation, if the external resistance torque exceeds the limit value, the elastic element is compressed, the steel ball slips against the semi-circular groove on the second pressure plate, and the second blade stops rotating. The maximum torque that can be transmitted is determined by the relationship between the clamping force of the elastic element on the second pressure plate and the torque.

[0036] like Figure 1-4 As shown, in order to illustrate how the main shaft and the first blade are fitted and fixedly connected, the present invention adopts a connection between the main shaft 1 and the first blade 2 through a flat key 10 and a sliding groove 11.

[0037] In this way, the main shaft and the first blade are connected by a key and a groove, and the torque can be transmitted from the main shaft to the first blade.

[0038] like Figure 1-4 As shown, in order to illustrate the connection between the second blade and the transmission sleeve, the present invention uses the second blade 6 and the transmission sleeve 4 to be connected by a sliding groove 11 and a flat key.

[0039] The second blade and the transmission sleeve are connected by a slide groove and a flat key. When the transmission sleeve moves axially relative to the main shaft, the transmission sleeve also moves axially relative to the second blade under the cooperation of the slide groove and the slider.

[0040] like Figure 1-4 As shown, in order to restrict the axial fixed connection between the first blade, the second blade, and the main shaft, the present invention adopts a limiting plate 12 at the end of the main shaft 1. The limiting plate 12 abuts against the end of the second blade 6 to restrict the axial movement of the first blade 2 and the second blade 6.

[0041] The axial movement of the first and second blades relative to the main shaft is restricted by the flat key and the limiting plate.

[0042] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
