Description

Technical Field

[0001] The utility model relates to the field of horizontal centrifuges, in particular to a horizontal centrifuge capable of automatically detecting leakage. Background Art

[0002] The horizontal centrifuge is composed of a drum and a spiral pusher rotating at a high speed in the same direction at a differential speed. The material enters the spiral inner cylinder through the feed pipe and enters the drum from the feed port. Under the action of centrifugal force, the heavier solid phase material is deposited on the drum wall to form a sediment layer. The spiral continuously pushes the deposited solid phase material to the cone end of the drum and discharges it out of the machine through the slag discharge port. The lighter liquid phase material forms an inner liquid ring, which continuously overflows the drum from the overflow port at the large end of the drum and is discharged out of the machine through the discharge port.

[0003] In the existing spiral horizontal centrifuge, the upper cover is generally openable, and the rotating shaft between the upper cover end and the drum end is generally sealed by a sealing ring. When in use, the drum is rotated by the rotating shaft, so the connection is prone to leakage of internal liquid, which is generally not discovered and maintained in time. Once the leakage is not discovered in time, it will lead to data loss or even pollution.

[0004] Therefore, it is necessary to propose a horizontal centrifuge with automatic leakage detection to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a horizontal centrifuge with automatic leakage detection, which can effectively solve the problems in the background technology.

The adapted lower cover shell 5, the upper cover shell 4 and the lower cover shell 5 are both semicircular, and the upper cover shell 4 and the lower cover shell 5 are open on one side facing the upper cover 2 and the frame 1. The upper cover shell 4 and the lower cover shell 5 are both provided with a first fixing block 13 on both sides of one end thereof, and the first fixing blocks 13 on the upper cover shell 4 and the lower cover shell 5 are locked by a second bolt 17. A moisture sensor 22 is provided on the inner side of the upper cover shell 4, and an alarm 8 electrically connected to the moisture sensor 22 is provided on the outer side of the upper cover shell 4.

[0027] Furthermore, a liquid discharge port 9 communicating with the lower cover shell 5 is disposed at the bottom of the lower cover shell 5 , and a receiving box 10 for collecting liquid is threadedly connected to the bottom of the liquid discharge port 9 .

[0028] In order to achieve fixation, a second fixing block 14 is fixedly provided on one side of the lower end of the lower cover shell 5 close to the frame 1. The second fixing block 14 is an arc-shaped block adapted to the lower cover shell 5. The second fixing block 14 is locked to the side wall of the frame 1 by multiple first bolts 16.

[0029] In order to facilitate the rapid fixation of the first bolt 16, a positioning assembly is also included, which includes a positioning pin 15 arranged on the side wall of the second fixed block 14. The corresponding part of the end of the frame 1 and the second fixed block 14 is rotatably connected with a clamping arm 11 for limiting the second fixed block 14 through a pin shaft 21. The end side wall of the frame 1 is provided with a positioning hole 7 adapted to the positioning pin 15, and the positioning pin 15 is plugged into the positioning hole 7.

[0030] In addition, it also includes a sealing component, which includes a receiving groove 18 arranged on the side of the lower cover shell 5 facing the frame 1, and the inner side of the receiving groove 18 is provided with an arc-shaped sealing strip 12 for movable sealing, and a spring 20 is arranged between the sealing strip 12 and the inner wall of the receiving groove 18, and one end of the sealing strip 12 protrudes from the side wall of the lower cover shell 5 when the spring 20 is in the reset state, and a rubber strip 19 for abutting against the side wall of the end of the frame 1 is arranged on the side of the sealing strip 12 away from the spring 20.

[0031] It should be noted that the utility model is a horizontal centrifuge with automatic leakage detection. When in use, the upper cover shell 4 and the lower cover shell 5 are placed on the outer side of the rotating shaft 3 at the end of the frame 1 and the upper cover 2, so that the upper cover shell 4 and the lower cover shell 5 are combined, and the first fixing block 13 is fixed by the second bolt 17, and then the upper cover shell 4 and the lower cover shell 5 are moved closer to the frame 1 and the upper cover 2. The sealing strip 12 contacts the side wall of the frame 1 through the rubber strip 19, so that the positioning pin 15 is inserted into the positioning hole 7, and then the lower cover shell 5 and the lower cover shell 5 are pushed as a whole, and then the spring 20 contracts. When the second fixing block 14 coincides with the pressing arm 11, the pressing arm 11 is rotated to press the lower cover shell 5. The clamping arm 11 is tightened, so that one end of the clamping arm 11 is displaced to the side of the second fixing block 14 away from the frame 1, thereby realizing the limitation of the second fixing block 14. At this time, since the rubber strip 19 is tightly fitted with the side wall of the frame 1, the sealing between the lower cover shell 5 and the frame 1 is increased, and then the first bolts 16 are screwed in and locked one by one. If leakage occurs during this period, it can be detected by the moisture sensor 22, and then the signal is transmitted to the alarm 8. The alarm 8 alarms, thereby promptly reminding the staff to perform maintenance and inspection. In addition, the liquid can be protected by the upper cover shell 4 and the lower cover shell 5, and collected by the drain port 9 and the receiving box 10.
