Description

Technical Field

[0001] The utility model relates to the technical field of horizontal spiral unloading centrifuges, in particular to an overflow regulating device for a horizontal spiral unloading centrifuge. Background Art

[0002] The horizontal spiral unloading centrifuge is mainly composed of a high-speed drum, a spiral with the same rotation direction as the drum and a slightly higher or lower speed than the drum, and a differential. It can automatically and continuously feed, wash, dehydrate, and discharge the suspension when running at full speed. An overflow port is opened on one side of the drum. The overflow port is an outlet for discharging liquid phase substances. In the past, the size of the overflow port opening was adjusted by an overflow plate. The disadvantage is that the height of the liquid flow port cannot be adjusted from the outside of the centrifuge. The position of the overflow plate can only be adjusted after the machine is shut down and the casing is opened, which is very inconvenient to use.

[0003] In order to solve the above technical problems, a Chinese patent with the authorization announcement number CN101628262B discloses an overflow regulating device in a sedimentation centrifuge, the principle of which is: a centripetal pump is arranged between the sleeve and the regulating rod, a liquid outlet channel is formed between the sleeve and the regulating rod, a liquid outlet port adapted to the liquid outlet channel is provided on the surface of the sleeve, and a liquid inlet tank adapted to the liquid outlet channel is provided inside the centripetal pump. When in use, the centripetal pump is driven to rotate by rotating the regulating rod, thereby adjusting the outlet height of the liquid inlet tank. However, the applicant found that the scheme still has defects: generally, 6-8 overflow ports are provided on the side of the drum, and each overflow port needs to be installed with this regulating structure. When adjusting, due to the "barrel effect", it is impossible to adjust only one overflow port, but to adjust multiple overflow ports. In the face of so many overflow ports, if they are adjusted one by one, not only the efficiency is low, but also time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] See also Figure 1-4 The utility model provides a technical solution: an overflow regulating device for a horizontal spiral unloading centrifuge, comprising: an overflow plate 4 arranged on one side of a drum 1 for adjusting the opening and closing size of an overflow port 2; a guide structure matched with each overflow plate 4, the guide structure being used to guide the overflow plate 4 to move along the direction of blocking the overflow port 2; in this embodiment, the guide structure comprises: a mounting plate 5 arranged on the side of the drum 1, the mounting plates 5 being arranged in pairs;

[0035] The above technical solution enables the overflow plate 4 to block the overflow port 2. By setting the mounting plate 5, a guide space for the overflow plate 4 is formed between adjacent mounting plates 5, ensuring that the overflow plate 4 can move along the guide space and preventing the overflow plate 4 from moving crookedly.

[0036] like Figure 4 As shown, the overflow regulating device further includes: a linkage member connected to each overflow plate 4 at one end, and the other end of the linkage member is connected to the driving member. When in use, the driving member synchronously drives all overflow plates 4 to move through the linkage member to adjust the opening and closing size of all overflow ports 2; in this embodiment, the linkage member includes: a connecting shaft 12 and hinges 13 provided at both ends of the connecting shaft 12, and one end of the connecting shaft 12 is directly or indirectly connected to the overflow plate 4 through the hinge 13;

[0037] like Figure 2 and Figure 3 As shown, the overflow regulating device further includes: a driving member arranged on one side of the drum 1; in this embodiment, the driving member includes: a rotating ring 15 rotatably arranged on the shaft end 3 of the drum 1, one side of the rotating ring 15 is connected to the hinge 13 at the other end of the connecting shaft 12; the overflow regulating device further includes: a convex ring 14 arranged on the surface of the shaft end 3, the convex ring 14 is rotatably matched with the rotating groove provided on the inner side of the rotating ring 15, a column 16 is arranged on the surface of the rotating ring 15, and the column 16 is rotatably connected to the hinge 13; the central axis of the rotating ring 15, the drum 1 and the shaft end 3 coincide with each other;

[0038] The above technical solution can be used to adjust the opening and closing sizes of multiple overflow ports 2 at one time. When in use, the swivel 15 is rotated around the convex ring 14, and the swivel 15 drives the overflow plate 4 to move through the column 16, the hinge 13 and the connecting shaft 12, thereby adjusting the opening and closing size of the overflow plate 4 relative to the overflow port 2. It is worth mentioning that the adjustment here does not completely limit the movement of the overflow plate 4, but only limits the maximum opening and closing degree of the overflow plate 4 relative to the overflow port 2. Since the drum 1 is driven by a motor to rotate at a high speed during operation, the overflow plate 4 will automatically move outward along the mounting plate 5 due to centrifugal force, and the swivel 15 exerts a pulling force on the overflow plate 4 through the column 16, the hinge 13 and the connecting shaft 12, so that the overflow plate 4 cannot completely open the overflow port 2, thereby achieving the maximum opening and closing size adjustment of the overflow port 2.

[0039] like Figure 3 As shown, in this embodiment, the overflow regulating device further includes: a limiting structure for limiting the rotation of the rotating ring 15 relative to the shaft end 3; in this embodiment, the limiting structure includes: a clamping body 17 provided on the surface of the shaft end 3; a screw 18, which cooperates with a thread groove 19 provided on the surface of the clamping body 17; a clamping plate 20 with one end rotatably connected to the screw 18, and a clamping space for clamping the rotating ring 15 is formed between the other end of the clamping plate 20 and the clamping body 17;

[0040] The adoption of the above technical solution can ensure that after the opening and closing size of the overflow port 2 is adjusted, the opening size change caused by external force is prevented from being inconsistent with the expected size. When in use, the screw 18 is driven to rotate by rotating the handle located at the outer end of the screw 18, and the screw 18 pushes the clamping plate 20 to clamp the surface of the swivel 15. The principle of this structure is similar to that of a brake pad.

[0041] like Figure 4 As shown, in this embodiment, the overflow regulating device further includes: a slide plate 7 with a slide groove 8, the slide groove 8 slidingly cooperates with a slide block 6 provided on the inner side of the mounting plate 5; a connecting rod 9 connected to the overflow plate 4 at one end, the other end of the connecting rod 9 passes through a rod groove 10 provided on the surface of the slide plate 7; a first elastic member 11 provided between the overflow plate 4 and the slide plate 7, the first elastic member 11 is used to push the overflow plate 4 to fit with the overflow port 2;

[0042] The above technical solution can prevent the existence of a gap at the fitting point between the overflow plate 4 and the overflow port 2. Since the first elastic member 11 is arranged between the slide plate 7 and the overflow plate 4, it can ensure that the first elastic member 11 pushes the overflow plate 4 and the overflow port 2 to fit together, thereby eliminating the gap between the overflow plate 4 and the overflow port 2 to the greatest extent.

[0043] like Figure 4 As shown, in this embodiment, the overflow regulating device further includes: a second elastic member 21 connected to the mounting plate 5 at one end, the other end of the second elastic member 21 is connected to the slide plate 7, and the force of the second elastic member 21 on the slide plate 7 is opposite to the force of the connecting shaft 12 on the slide plate 7;

[0044] The above technical solution can ensure that when the size of the overflow port 2 is adjusted, forces are applied to both sides of the overflow plate 4 or the slide plate 7, so that the opening size of the overflow port 2 can be observed conveniently and accurately.

[0045] Working principle: When in use, the swivel 15 is rotated around the convex ring 14, and the swivel 15 drives the overflow plate 4 to move through the column 16, the hinge 13 and the connecting shaft 12, so as to adjust the opening and closing size of the overflow port 2 of the overflow plate 4, and then the screw 18 is driven to rotate by rotating the handle located at the outer end of the screw 18, and the screw 18 pushes the clamping plate 20 to clamp the surface of the swivel 15 to prevent the swivel 15 from loosening.

[0046] Thereby completing a series of tasks, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
