Description
Technical Field
The utility model belongs to the technical field of mechanical control, concretely relates to rotatory detection and controlling means of high-efficient thickener harrow frame.
Background
The central transmission high-efficiency thickener has the outstanding advantages, is widely adopted in the production of enterprises such as mineral separation and the like at present, is also an indispensable key device of the whole production system, and mainly undertakes the concentration of ore pulp in the production system, so the stable operation of the high-efficiency thickener is the key for ensuring the normal production of concentration operation, and the stable operation of the rake rack is the key for the normal operation of the high-efficiency thickener. Because the harrow frame is in the rotation of high-efficient dense pond ore pulp, operation and maintenance personnel can't the actual rotation situation of observing the harrow frame directly perceivedly, if the harrow frame is in under the rotation situation that stops for a long time, operating personnel can't in time discover to handle, will certainly lead to the fact the damage of certain degree to equipment, bring very big difficulty to entire system production organization simultaneously.
SUMMERY OF THE UTILITY MODEL
To the problems and deficiencies existing in the prior art, the utility model provides a high-efficient thickener harrow frame rotation detection and control device.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a rotatory detection and controlling means of high-efficient thickener harrow frame, includes the transmission shaft and drives transmission shaft pivoted transmission, is equipped with down the bearing gland on the transmission, and the transmission shaft passes through transmission shaft connecting bolt fixed connection with transmission, controlling means still include iron sheet and electromagnetism proximity switch, the iron sheet be the channel-section steel structure, first hole and second hole have been seted up at its both ends, first hole is connected through fixing bolt with lower bearing gland, installation electromagnetism proximity switch on the second hole, electromagnetism proximity switch is located transmission shaft connecting bolt's top.
Furthermore, the distance between the electromagnetic proximity switch and the transmission shaft connecting bolt is 5 mm.
Furthermore, the transmission device drives the transmission shaft to rotate after being started, and the electromagnetic proximity switch detects the number of rotating circles of the transmission shaft connecting bolt.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses an electromagnetism proximity switch detects transmission shaft connecting bolt pivoted number of turns, and then judges the transmission shaft pivoted number of turns, and then judges whether the rotation of thickener rake is normal, the utility model discloses avoided relying on operating personnel experience to judge in the past, lack the problem of accurate fault diagnosis foundation, the utility model discloses it is more convenient that operating personnel of being convenient for observe and maintenance personal fault handling, solved the rake because of stopping the harm of rotation to production and equipment.

In the figure: 1. the electromagnetic proximity switch comprises a transmission shaft, 2. a transmission device, 3. a lower bearing gland, 4. a transmission shaft connecting bolt, 5. an iron sheet, 51. a first hole, 52. a second hole, 6. an electromagnetic proximity switch and 7. a fixing bolt.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, a device for detecting and controlling the rotation of a rake of a high-efficiency thickener comprises a transmission shaft 1 and a transmission device 2 driving the transmission shaft 1 to rotate, wherein the transmission device 2 is provided with a lower bearing gland 3, the transmission shaft 1 is fixedly connected with the transmission device 2 through a transmission shaft connecting bolt 4, the control device also comprises an iron sheet 5 and an electromagnetic proximity switch 6, the iron sheet 5 is in a channel steel structure, first hole 51 and second hole 52 have been seted up at its both ends, and first hole 51 is connected through fixing bolt 7 with lower bearing gland 3, installs electromagnetism proximity switch 2 on the second hole 52, and electromagnetism proximity switch 2 is located transmission shaft connecting bolt 4's top, and electromagnetism proximity switch 2 is 5mm apart from transmission shaft connecting bolt 4, and transmission 1 rotation is driven to transmission 2 after the start-up, and electromagnetism proximity switch 6 detects the rotatory number of turns of transmission shaft connecting bolt 4.
The utility model discloses when specifically using, the thickener starts back transmission 2 and drives transmission shaft 1 rotatory, electromagnetism proximity switch 6 detects the 4 rotatory quantity of transmission shaft connecting bolt, thereby calculate transmission shaft 1 rotation number of turns in unit interval, detect 1 rotation number of turns of transmission shaft according to electromagnetism proximity switch 6, judge whether 1 rotation of transmission shaft is normal, electromagnetism proximity switch 6 feeds back the control system of testing result to the thickener, the control system of thickener sets up normal rotation interval, if rotation number of turns is less than or surpasss and sets for rotatory interval, then control system sends stop instruction, send audible and visual alarm signal simultaneously, examine equipment with the suggestion operating personnel, thereby realize the accurate control to equipment, if rotation number of turns and set for rotatory interval phase-match, then can not have the suggestion action.
