Storage bin with arch breaking device

Abstract

The invention discloses a storage bin with an arch breaking device, comprising a storage bin body (1) and a material conveying mechanism (2). The upper part of the storage bin body (1) is in a cylindrical shape, and the lower part of the storage bin body (1) is in a tapered funnel shape. The material conveying mechanism (2) is arranged below the storage bin body (1), and the arch breaking device is arranged on the storage bin body (1). The storage bin with the arch breaking device also comprises a controller (3) and an infrared inductor, wherein the infrared inductor is electrically connected with the controller (3). The infrared inductor comprises an infrared transmitter (4) and an infrared receiver (5), wherein the infrared transmitter (4) and the infrared receiver (5) are respectively arranged between the storage bin body (1) and the material conveying mechanism (2), and are respectively distributed at two sides of a lower outlet of the storage bin body (1). By adopting the storage bin with the arch breaking device, whether blocking and arch forming in the storage bin occurs or not can be automatically judged, whether the arch breaking device is started to work or not can be judged according to the arch forming condition, and furthermore, relatively uniform conveying of material can be achieved.

Description

technical field [0001] The invention relates to the field of feed bins, in particular to a feed bin with an arch breaking device. Background technique [0002] In modern industry, the number and capacity of silos are increasing, and the frequency of use is also increasing. Relying on the bulk material to flow into the silo by its own gravity, material arching, sticking, clogging and other phenomena are prone to occur, especially when the material contains a large amount of water and mud. Once the silo is blocked, it will not only affect the full play of the silo, but also seriously affect the continuity of the production process. Therefore, how to remove situations such as silo arching, bonding, and blockage in the safest, most energy-saving, and fastest method has become an urgent problem to be solved. At present, the methods of clearing and breaking arches include artificial arch breaking method, water conservancy arch breaking method, wind force arch breaking method (ai...

Problems solved by technology

However, these methods have some disadvantages. For example, the artificial arch breaking method is labor-intensive and should not be widely used; the hydraulic arch breaking method will additionally increase the moisture content of the material; the wind force arch breaking method is noisy, and it is difficult to completely clean materials with strong adhesion and poor fluidity. The arch breaking device of the new bulk machine is complicated and installed in the silo, so the reliability is poor; the arch breaking of the carriage needs to be driven by hydraulic pressure, the structure is complex and the energy consumption is large

Because material arching does not exist all the time, it only exists intermittently. For example, it takes a while to re-arch after breaking the arch. In the above methods, there is no device for judging whether the material is arching and whether the blockage is eliminated. The arch blocking and breaking mechanism needs constant movement, which consumes a lot of energy and has an adverse effect on the life of the equipment

In addition, the patent application number 201020676121.5 published by the State Intellectual Property Office is a utility model patent "arch breaking device for silos", which includes a rotating shaft and an arch breaking unit connected to the rotating shaft. The arch breaking unit includes a fixed sleeve and a movable sleeve. The rotation of the rotating shaft drives the arch breaking unit to break the arch on the inner wall of the silo. Although this patented technology can overcome the disadvantages of artificial arch breaking, water conservancy arch breaking, and wind force arch breaking to a certain extent, the installation of many arch breaking units will inevitably affect the material. At the same time, it is difficult to control the intermittent work of the arch breaking device, and the degree of automation is low
