Description

Prevent blockking up feed arrangement in coordination

Technical Field

The utility model relates to a prevent blockking up feed arrangement in coordination belongs to mineral smelting technical field.

Background

In the smelting process of minerals such as magnesite, after the raw materials are subjected to primary crushing and other treatments, the main raw materials and various smelting auxiliary materials are generally required to be added into a smelting device together for smelting. In the smelting process, various auxiliary materials, auxiliaries and the like have great influence on the success and the efficiency effect of smelting. Therefore, how to realize accurate synchronous feeding is very key for smelting minerals. However, in the actual production process, the raw materials are not uniform in characteristics such as particle size after simple primary treatment, and the feed inlet is often blocked in the feeding process. On one hand, manual cleaning is needed after blockage, and the working efficiency is influenced; on the other hand, the asynchronism of the feeding of various materials can also change the proportion of various raw and auxiliary materials in the smelting process, thereby influencing the smelting effect.

In order to prevent the blockage problem of various raw and auxiliary materials in the feeding process, the feeding device mainly adopts two types of feeding devices, namely a horizontal shaft type rotary feeder and a vertical shaft type rotary feeder in the prior art. Among them, the horizontal axis type rotary feeder generally conveys the material from the top to the bottom by the rotation of the rotary shaft by providing a fin plate on the rotary shaft which rotates with the shaft. This approach has the advantage of being less prone to clogging, but is not conducive to co-axial co-feed due to the use of a horizontal spindle. Due to the fact that the main material and the auxiliary material are different in usage amount, the main material and the auxiliary material have great difference in pressure to the shaft in the feeding process, and the main shaft can be bent and deformed or even damaged after being used for a long time. The vertical shaft type rotary feeder has the advantage of convenient cooperative feeding, but the feeding surface is generally a conical curved surface, so that the material outlet is smaller, and the blockage is easily caused.

Fig. 1 is a schematic front view of a co-feeding device for preventing blockage in a preferred embodiment of the present invention. As can be seen from fig. 1, the feeding device comprises a powerful motor, i.e. a rotary power unit 1; two rotary distributing cylinders, namely a rotary distributing cylinder I2 and a rotary distributing cylinder II3, which are connected with a rotary power output shaft 11 of the rotary power device 1 through a transmission belt; two feed hoppers positioned above the rotary distributing cylinder and a smelting device 6 positioned below the rotary distributing cylinder; the bottom of the discharge ports of the two rotary distributing cylinders is provided with an anti-blocking rotating plate 9. One end of the anti-blocking rotating plate 8 is driven to rotate by the motor 7, and the anti-blocking rotating plate 9 is provided with a pressure sensor 8 for detecting the pressure of the material discharged from the discharging port. The pressure sensor 8 is interlocked with the motor 7, and the motor 7 is interlocked to start after the pressure of the pressure sensor 8 exceeds a set value, so that the motor drives the anti-blocking rotating plate 8 to rotate. The smelting device 6 is fixedly connected with the rotary distributing cylinder through a supporting frame 61 so as to stabilize the distributing cylinder. The rotary distributing cylinder consists of an inner part and an outer part, wherein the inner part is a rotating part, and the outer part is a fixing part. The rotating part is a combination body formed by a cylinder and an inverted round table, and the fixing part is the inverted round table which has the same shape as the inverted round table but is slightly larger in size. The rotating part and the fixed part are movably connected relatively at the discharge outlet of the bottom part through a bearing. Feed hopper I4 and feed hopper II 5 insert respectively in rotary material section of thick bamboo I2 and rotary material section of thick bamboo II3, for preventing that the feed hopper from hindering the rotary part motion, the feed hopper bottom does not contact with the rotary part medial surface. The feed hoppers are respectively and independently fixed. Meanwhile, the rotary power device 1 is also independently fixed.

Fig. 2 is a schematic view of a top view of an anti-blocking rotating plate according to a preferred embodiment of the present invention, wherein the dotted line is the diameter of the discharge hole. As can be seen from fig. 2, the anti-clogging rotation plate 9 is formed by integrally molding a substantially rectangular bar plate (rotation plate 91) and an anti-clogging cap 93. A through hole 92 is formed at the rear of the rotating plate 91, and the through hole 92 is used for connecting with an output shaft of the motor 7 so as to rotate under the driving of the motor 7. Meanwhile, a reducing hole 94 having a diameter 50% of the diameter of the discharge hole is formed at the center of the anti-clogging head 93, so that the effect of doubling the flow area of the outlet can be achieved after the reducing hole is rotated.
