Abstract

Provided is a cooling and dosing feeder of a water leg, comprising a hopper 11, a blending device 9, a spiral 1 and a driving device, wherein the spiral 1 consists of a worm feeding groove 3 and a worm feeding shaft 2, the driving device is composed of a gear pair 12, a bearing 15 and a bevel gear 8. The positions of a material outlet opening 7 disposed on the lower portion of the hopper and a spiral material inlet opening 4 are provided in the front of the spiral 1 which is close to a spiral material outlet opening. The passage way from the lower hopper 7 of the hopper to the spiral material inlet opening 4 is provide with a shifting fork 5 for shifting materials. The water leg 10 is disposed at the external portion of the hopper. A semi-circular water leg 16 is arranged on the lower portion of the spiral. The spiral material inlet opening is mounted in the front of the spiral. After entering into the spiral, the material is pulled out in a short time. The contact time of the material and the blade arranged on the worm feeding shaft is short without generating heat by frication. Simultaneously, the external portions of the hopper and the spiral are provided with water legs. The temperature is lowered by the utilization of recycle water, which enables the hopper and the spiral to keep in lower temperature. Therefore, the materials of low fusing point can not be tacky and caking in the summer with high temperature, and then the free flowing is kept and the accurate dosing addition is guaranteed.

Description

A kind of water leg cooled trace feeder

The utility model relates to a kind of water leg cooled trace feeder, can be used for the micro-continuous-feeding of industries such as food, powder process, chemical industry, feed, and especially suitable fusing point is low, the accurate continuous-feeding of the material of free-running property difference.

At present, the micro-feeder of selling on the market, generally be designed to the spiral charging, the position of screw feed en-trance is generally at the postmedian of spiral, TWLL2a powder trace feeder as the production of South Sea grain machinery factory, because feed entrance point is at the postmedian of spiral, so material will be by certain distance in spiral, for some materials, as food emulsifying agent " CSL one sodium " when summer temperature is high the caking because the low material of fusing point itself easily is clamminess, when adding by spiral, in spiral, promote material forward by the blade on the screw feeder axle, material for a long time in spiral with blade friction Yi Shengre, bonding can't be added.

The purpose of this utility model is to provide a kind of low-melting-point material that is applicable to add, even, the accurate micro-feeder that quantitatively adds of feed.

The purpose of this utility model is achieved in that

A kind of water leg cooled trace feeder comprises hopper 11, mixing device 9, the spiral of being made up of screw feeder groove 3 and screw feeder axle 21, the driving device of being made up of gear mesh 12, bearing 15, bevel gear 8; The position of the discharging opening 7 of hopper bottom, the inlet point 4 of spiral is at the close spiral discharging mouth in the front portion of spiral 1, the shift fork 5 that has material toggling to use 4 the passage from hopper feed opening 7 to screw feed en-trance, the hopper outside is provided with water leg 10, and semicircle water leg 16 is arranged at the spiral bottom.

Because hopper feed opening and screw feed en-trance all are positioned at the spiral front portion, very short time just was pushed out after material entered spiral, blade on material and the screw feeder axle is short contact time, the phenomenon that can not produce that friction generates heat, add in the outside of hopper and spiral water leg is all arranged, utilize circulating water cooling, can make hopper and spiral keep lower temperature, low-melting-point material is not clamminess, do not lump, keep free-running property, adjust addition, guarantee that accurate quantification adds by adjusting motor speed.

The utility model is described in further detail below in conjunction with accompanying drawing and example:

Fig. 1 is the structural representation of embodiment;

Fig. 2 is the sectional side elevation of embodiment spiral;

Fig. 3 is the cross-sectional figure of embodiment spiral;

Fig. 4 is that the A of embodiment spiral is to view.

As shown in Figure 1, this water leg cooled trace feeder is by hopper 11, mixing device 9, and the spiral of forming by screw feeder groove 3 and screw feeder axle 21, the driving device of being made up of gear mesh 12, bearing 15, bevel gear 8 etc. is formed.Hopper 11 is positioned at the top of spiral 1, there is water leg 10 outside, mixing device 9 is installed in the hopper 11, the action of mixing device 9 by bevel gear to 8, the driving device that gear mesh 12 is formed drives, motor 14 links to each other with retarder 13, retarder 13 links to each other with gear in the gear mesh 12, relative gear links to each other by an end of gear in bearing 15 and another gear mesh 12 and screw feeder axle 2, another relative gear links to each other to 8 with bevel gear, bevel gear links to each other with mixing device 9 to 8 and drives mixing device 9 actions, feed opening 7 is arranged at hopper 11 bottoms, feed opening 7 is formed blanking channel 6 with spiral material hole 4, the feed opening 7 of hopper 11 and the inlet point 4 of spiral 1 are positioned at the front portion of spiral 1, with the distance of the discharging opening of spiral 1 be 3-4cm, a material poking fork 5 is arranged in blanking channel, material poking fork 5 drives action by bevel gear to 8, windrow not when making blanking, blanking is unobstructed.

The feed process: material is packed into behind the hopper, arrive the inlet point of spiral down by the feed opening of hopper bottom, mixing device in the hopper stirs material, makes the material blanking even, not putty, material enters spiral by inlet point, screw feeder axle in the spiral rotates, and promotes material to discharging opening, because the distance of turnover material is shorter, material just is pushed out in a short period of time, reaches the purpose of dosing.
