Abstract

The utility model discloses a feeding device of a high-speed single-machine flour mill, which is characterized in that a material-discharging port end of a hopper is provided with a feeding box body,an outlet of which is communicated with an inlet of a milling roller; and the milling roller is connected with a power source in a transmission manner by chain transmission. The feeding box body is internally provided with a roller shaft; the feeding box body at one side of the roller shaft is provided with an arc eccentric plate; the upper part and the upper end of the arc eccentric plate are respectively arranged on the feeding box body by a pin shaft and a tension spring; and the arc eccentric plate is contacted with the roller shaft in a tangential manner, and the length of the arc eccentric plate is matched with that of the roller shaft. As the material-discharging port part of the hopper is added with a feeding roller and a feeding micro-adjusting device, the feeding is even and no blockage or springing occurs, thus improving smoothness of feeding, reducing operating difficulty of the equipment, and improving the production efficiency by 15 to 25 percent. As the rotating speed ofthe milling roller is improved, the feeding device accelerates the milling speed of the materials, improves the unit yield of the flour mill, reduces energy consumption and production cost, can improve the unit yield by 0 to 15 percent, improves production efficiency, and has low noise and convenient operation and maintenance.

Description

A kind of high speed unitary powder mill group drawing-in device

Technical field

The utility model relates to a kind of wheat flour milling equipment, relates in particular to abrasive dust unit drawing-in device.

Background technology

At present, the monolateral flour mill that utilizes of extensive use carries out in the wheat flour milling equipment, the hopper feeding all adopts material gravity flow mode to enter pulverized coal preparation system, adopt the feeding manner of this structure, material easily stops up at hopper discharging opening place, cause work to be interrupted, influence carrying out continuously of powder process, simultaneously, the rotating speed of flour mill all is the rotating speed of employing standard, be generally 450r/min～550r/min, the average product of grinding roller is 5.5～7.7mm/100kg (wheat) d, yields poorly the energy consumption height, the production cost height does not meet current requirement of setting up conservation-minded society.

Summary of the invention

The utility model provides a kind of abrasive dust unit, easily stops up, yields poorly, defectives such as energy consumption height to overcome existing unitary powder mill material.

The scheme that its technical problem that solves the utility model adopts is: be provided with a feeding casing at the hopper discharge port end, and feeding casing outlet continuous grinding roller inlet, grinding roller is in transmission connection by chain transmission and power source.

Be provided with a roll shaft in the described feeding casing, installing one arc eccentric disk on the feeding casing of roll shaft one side, the top of arc eccentric disk and upper end are installed on the feeding casing by bearing pin and extension spring respectively, and the arc eccentric disk contacts with the roll shaft tangent line, and the length of arc eccentric disk and roll shaft length are complementary.

Chain pitch is 11～13mm, i.e. the pitch of chain transmission middle sprocket and chain is 11～13mm.

The beneficial effects of the utility model:

1. owing to the feed system to the abrasive dust unit improves, promptly feeding roller and feeding micromatic setting have been installed additional at hopper discharging opening place, make feeding even, do not stop up, not arch camber, improved the fluency of feeding, and reduced the operation easier of equipment, with the unitary powder mill of existing identical working ability relatively, can enhance productivity 15～25%.

2. owing to fast, the slow roller transmission mechanism with flour mill improves, promptly reduced the pitch of sprocket wheel and chain, improved roller speed, made material by the speeding up of grinding roller milling zone, thereby improved the specific yield of flour mill, energy consumption and production cost have been reduced, compare with the unitary powder mill of existing identical working ability, can improve specific yield 10～15%, improved production efficiency greatly, and noise is low, and operating maintenance is easy.Mill speed can be brought up to 1000r/min, makes material by the speeding up of grinding roller milling zone, thereby makes the output of whole powder process unit significantly be improved, and the average product of grinding roller rises to 4.4～5mm/100kg (wheat) d.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the utility model structural representation.

Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.

The specific embodiment

As shown in Figure 1 and Figure 2, be provided with a feeding casing at hopper 1 discharge port end, feeding casing outlet continuous grinding roller inlet, grinding roller is in transmission connection by chain transmission and power source.Be provided with a roll shaft 6 in the described feeding casing, installing one arc eccentric disk 5 on the feeding casing of roll shaft 6 one sides, the top of arc eccentric disk 5 and upper end are installed on the feeding casing by bearing pin and extension spring 7 respectively, arc eccentric disk 5 contacts with roll shaft 6 tangent lines, and the length of arc eccentric disk 5 and roll shaft 6 length are complementary.

Chain pitch is 11～13mm, and the chain transmission middle sprocket between fast roller promptly of the present utility model and slow roller and the pitch of chain are respectively 11～13mm.

In pulverizing process, when material enters pulverized coal preparation system from hopper 1, open bin gate 2 earlier by bin gate handle 4, the feeding regulating rod 3 of regulating micromatic setting then makes bin gate 2 reach correct position, and material evenly enters pulverized coal preparation system under the rotation of feeding roller 6.
