Description

Material inlet of bulk machine

Technical Field

The invention relates to the field of machinery, in particular to a feeding port of a bulk machine.

Background

The bulk machine is mainly used for loading and unloading bulk powdery materials, and is widely applied to the fields of electric power, building materials, metallurgy, coal, grain, chemical industry and the like. The bulk loader carries out loading or shipping operation on the materials from the material warehouse, can be interlocked with feeding equipment below the material warehouse to operate, automatically stops loading after the tank car is filled, and realizes automation of loading and unloading processes. The loading device has the characteristics of simple structure, reliable operation, high loading efficiency and relatively less dust pollution, and is ideal equipment for loading and shipping bulk powdery materials. People are in the dry likepowder to some bulks, when granular thing transports, need carry out the loading to it and handle, present way sets up the unloading pipe mostly, dust absorption fan and material switch door, such apparatus structure is too crude, mainly lean on manual operation when using, the operation is complicated, and unloading pipe and car loading port cooperation are not inseparable, the material is loaded and needs artifical to be observed with the naked eye, it is too much to control not good probably to produce the material, the not situation down of carrier loader splendid attire, need handle, simultaneously, still can cause the car to load inefficiency, the serious problem of dust pollution.

The existing bulk machine, such as the invention patent: 20162005112X proposes a bulk material loader, which can effectively improve the efficiency of bulk materials, simultaneously weigh the bulk materials each time in the bulk process, and reduce the raised dust generated in the bulk process, but the feed inlet is too small, so that the materials are easily clamped at the feed inlet, when the feed inlet needs to be closed in an emergency, the feed inlet cannot be closed in time, the materials continuously fall, and the materials are wasted. The invention has the following patents: 2014105157023 provides a feed inlet, the effect of feed inlet outer wall is flourishing material, rotates rotatory handle during the use to drive rotator and agitating unit and rotate, the rotary action through agitating unit makes the quick entering bulk machine of material, but this feed inlet often because the material is put into the too much condition that takes place to block up, leads to the feeding to be not smooth and easy. The invention has the following patents: 2018103484300A feed inlet structure on a rotary vibrating screen is provided, wherein a discharge port on the feed inlet is fixed with a flexible connection fixed end through a hose clamp, the flexible connection fixed end is flanged outwards from the feed inlet, so the joint of the flexible connection fixed end and a feed outlet forms a smooth joint surface, and no redundant burr and shuttle angle exist at the joint surface, thereby overcoming the problem that the joint surface is easy to accumulate materials, but the joint of the flexible connection and the hose clamp is easy to accumulate materials and not easy to clean when in feeding. The feed opening is easy to block for a long time. The invention has the following patents: 2018216093789 provides a feed port for transporting concrete aggregate, wherein a screen can filter out large aggregates, small aggregates can leak into the feed port from the screen, and the time for the aggregates to enter the feed port is delayed to a certain extent, so that the feed port is prevented from being blocked; dust excluding hood, dust bag can effectual absorption raise dust, and the air exhauster can be with the better workplace of taking out of raise dust, reduces the harm to the staff. However, the feed inlet cannot control the size of the falling material and the flow rate of the material.

Furthermore, a grizzly screen is arranged above the valve plate inside the feeding port, and mounting holes for mounting the grizzly screen are formed in the wall of the feeding port.

Furthermore, the thickness of the middle part of the valve plate is larger than that of the two ends, and the cross section is in a diamond shape.

Furthermore, a vibrator is fixed on the wall of the feeding port.

Further, the driving device is a motor or an air cylinder.

Furthermore, a storage battery for emergency power supply is connected to the driving device.

Furthermore, the driving device is a direct current motor, and the direct current motor is connected with the oscillating rod through a speed reducer.

Furthermore, an infrared height measuring device for measuring the material accumulation condition is arranged on the inner side of the material inlet of the bulk machine.

Furthermore, the infrared height measuring device is divided into two stages, when the material reaches the first stage, the infrared height measuring device gives an alarm, when the material reaches the second stage, the infrared height measuring device gives an electric signal, and the driving device is controlled to close the feeding port.

Compared with the prior art, the invention has the following advantages:

Detailed Description

As shown in fig. 1 and 2, a material inlet 7 comprises a material inlet wall 1, a mounting hole 2, a shutter valve 3, a hopper 4, a swing device 5, a bulk material machine body 6 and a vibrator 8.

The material gets into through pan feeding mouth 7, pan feeding mouth wall 1 is connected with hopper 4, adopts rectangle interface and bore size unanimity, makes the material velocity of flow improve greatly, and work efficiency obtains improving. The vibrator 8 is installed on the outer wall 1 of the feeding hole, and is opened when the material flowability is poor, so that the material can smoothly fall. Louvered valve 3 is in pan feeding mouth wall 1, and mounting hole 2 is equipped with the check sieve, need not use the check sieve at ordinary times, puts the check sieve through mounting hole 2 pendulum when material granule is irregular and mobility is not good and goes up to play the cushioning effect, avoids appearing blocking the material in louvered valve 3 department. The swing device 5 is connected with the louver valve 3 through a hinged connecting sheet, and a motor and a speed reducer (not shown in the figure) drive the swing device 5 to control the rotation of the louver valve 3. The opening is the biggest when the valve board is upright, and the opening is sealed when rotating 90 degrees. An emergency storage battery can be installed on the motor. Hopper 4 is connected with bulk cargo organism 6, and the material gets into bulk cargo organism 6 through the hopper. Meanwhile, the device is provided with an infrared measurement and control device, so that early warning can be given in advance when the material reaches a certain height, and the valve can be automatically closed when the material exceeds a specified height.

Hopper and tripe formula valve are used for accepting the material that the feed bin falls and the velocity of flow of appropriate control material, and the valve drives through direct current motor and speed reducer, thereby can adjust the velocity of flow of the aperture control material whereabouts of tripe valve simultaneously, can accurately control the flow of material to realize remote control by the operation panel. The storage battery device can ensure the automatic closing of the valve when power failure occurs accidentally, thereby avoiding the accumulation caused by the falling of a large amount of materials in the upper storage bin under the out-of-control state.

The above examples are only described to help understand the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
