The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1 to 7, the present invention provides a device for sampling a deep tank of a slurry in a flotation machine, comprising: pull rod 1, nylon rope 2, round pin axle 3, rings 4 and sampling subassembly. One end of a pull rod 1 is connected with a sampling assembly, a lifting ring 4 is arranged on the pull rod 1, a nylon rope 2 penetrates through the lifting ring 4, the nylon rope 2 penetrates through a circular hole on a pin shaft 3 to be connected with the pin shaft 3, and the pin shaft 3 penetrates through the lifting ring 4.
In some more preferred embodiments, a plurality of hanging rings 4 are arranged, and the pin shaft 3 sequentially passes through the hanging rings 4 on the pull rod 1 from top to bottom to play a role of fixing the nylon rope 2. A plurality of hanging rings 4 are connected with the pull rod 1 through threads.
In some more preferred embodiments, the sampling assembly comprises: steel ring 5, elastic cord 6, rubber ball 7, sampling tube 8, adapter sleeve 9 and ferrule 10. The rubber balls 7 are provided in two and are connected together by elastic strings 6. The two ends of the elastic rope 6 are provided with steel rings 5, the steel rings 5 penetrate through the pin shafts 3, and the aperture of the steel rings 5 can ensure that the pin shafts 3 penetrate through the steel rings. The connecting sleeve 9 is connected with the sampling tube 8 through a pipe hoop 10. One end of the pull rod 1 is connected with the connecting sleeve 9 through threads, and can also be welded together.
In some more preferred embodiments, the tie rod 1 is screwed or integrally formed with the connecting sleeve 9. The sampling tube 8 is provided with a scale, and the volume of the solution contained in the sampling tube can be read. The inner walls of the two ends of the sampling tube 8 are chamfered, so that the rubber ball 7 is tightly attached to the sampling tube.
In some more preferred embodiments, the rubber ball 7 is solid. The rubber ball 7 is provided with a through hole along the ball diameter direction, the aperture ensures that the elastic rope 7 can pass through the through hole, no gap exists between the rubber ball 7 and the through hole, and ore pulp and air can not pass through the through hole. The rubber ball 7 is fixed on the elastic rope 6, can be stuck by glue or knotted on the elastic rope 6, and ensures that the rubber ball 7 cannot slide on the elastic rope 6. And the distance between the two rubber balls 7 is moderate, so that when the rubber balls 7 just block the two ends of the sampling tube 8, the elastic rope 6 between the rubber balls 7 is in a tensioning state, and the two rubber balls 7 can be moved to a state of just being clamped on the outer wall of the sampling tube 8 by manual force. The rubber ball 7 is fixed in position on the bungee cord 6.
In some more preferred embodiments, the outside diameter of the tie rod 1 is 10-50 mm, and the tie rod 1 is telescopic.
The working principle of the invention is as follows: before sampling, the rubber ball 7 is moved to the position of the open state shown in fig. 1 and 2, and meanwhile, the pin shaft 3 passes through the last but one lifting ring 4 at the tail end of the pull rod 1, then sequentially passes through the steel rings 5 at the two ends of the elastic rope 6, and finally passes through the lifting ring 4 at the tail end. The bungee cord 6 is now in a taut state. The rubber ball 7 is just clamped on the outer wall of the sampling tube 8 through the pin shaft 3 and cannot rebound.
Then, the sampling tube 8 is inserted into the flotation tank, and the angle between the pull rod 1 and the sampling tube 8 is rotated to ensure that the sampling tube 8 is in a vertical state. At this time, the ore pulp flows through the sampling tube 8, and the ore pulp in the sampling tube 8 is completely communicated with the ore pulp in the flotation cell, so that the gas content is kept consistent. Then the nylon rope 2 is pulled to draw out the pin shaft 3 from the hanging ring, the elastic rope 6 and the steel ring 5 are separated from the constraint of the pin shaft 3, the rubber ball 7 starts to rebound, and the rubber ball is tightly attached to the two ends of the sampling tube 8 under the action of the pulling force of the elastic rope 6. The ore pulp in the sampling tube 8 is isolated from the outside ore pulp. Taking out the sampling tube 8, vertically placing the sampling tube 8, and calculating the gas content of the ore pulp by reading the volume of the ore pulp in the sampling tube 8.
Assuming that the total volume of the sampling tube 8 closed by the rubber ball 7 is V1 and the read pulp volume is V2, the gas content of the pulp is
By the method, the measurement of the gas content at any position in the flotation tank can be realized. In actual industrial production, the comprehensive gas content of ore pulp in a whole tank flotation machine is often required to be measured. The specific measurement method is as follows.
The ore pulp in the flotation tank is equally divided into N depths according to different depths of the longitudinal section, and the gas content of the ore pulp at each depth position is measured by adopting the gas content measuring device. The measurement results are used as the comprehensive gas content of the ore pulp in the depth area. Taking fig. 7 as an example, a total of 4 depths were measured, and the gas contents of each depth were ε 1, ε 2, and ε 4. The slurry volumes for each zone are V1, V2, V3 and V4, respectively. The method for calculating the comprehensive average gas content epsilon of the whole flotation tank comprises the following steps:
finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
