Abstract
The invention provides a spiral medicine addition device capable of smoothly conveying moisturized medicine powder such as moisturized dry powder and the like. The spiral medicine addition device comprises a feeding hole, a conveying section and a discharge hole, wherein a conveying screw rod is arranged in the conveying section; an opening which has a gradually decreased cone shape is formed at the connection position between the conveying section and the feeding hole; and a heating device is arranged on the conveying section. In the conveying process, the medicine addition device can pulverize caked materials and can heat the materials to make the materials loosened; and after the conveying process is finished, the materials cannot be moisturized by external moisture, so that medicines can be smoothly and efficiently added.
Description
Technical field
The present invention relates to a kind of chemicals dosing plant, relate in particular to a kind of chemicals dosing plant of carrying the medicinal powder that makes moist, lumps that is applicable to, the conveying after making moist such as dry powder (lime).
Background technology
Dry powder (lime powder) occurs building bridge because of the long-term long-pending feed bin that is placed on, even caking phenomenon occurs, influences the transmission of medicament, the degree of uniformity in the transmission course, and influence adds the accuracy rate of medicament.Therefore, need a kind ofly to be beneficial to dry powder (lime) input, and have and pulverize, the constant temperature protection against the tide, in time cut off the dosing feedway of extraneous moisture function.
Summary of the invention
The present invention is directed to above-mentioned defective, the spiral chemicals dosing plant that purpose is to provide the smooth and easy conveying of a kind of energy to make moist the medicinal powder that makes moist such as back dry powder.
Technical scheme of the present invention is: the present invention includes inlet point, transportation section and discharging opening, conveying screw rod is set in the transportation section, the connecting portion of transportation section and inlet point is the cone-shaped that opening successively decreases gradually, and the transportation section is provided with heating arrangement.
Described inlet point is the open type bell mouth shape.
Described transportation section comprises conical section and linear portion, and conical section and inlet point engage, and the linear portion two ends engage with conical section, discharging opening respectively.
Described discharging opening is provided with tide gate, and tide gate is provided with pressure sensor.
Described conveying screw rod is driven by worm reducer by inorganic variable-speed motor.
Advantage of the present invention is: 1) connecting portion of the present invention in inlet point and transportation section is the cone-shaped that opening successively decreases gradually, material is when carrying like this, because diminishing of opening, screw rod and transportation section inwall can form a squeese pressure to material, help pulverizing of caking materials, guarantee normally carrying out of mass transport; 2) heating arrangement is established in the transportation section, in material conveying process, material is heated, and makes material become loose and its adhesive ability is each other diminished, and prevents that material lumps again because of mutual extrusion in course of conveying, with normally carrying out smoothly of guaranteeing to carry; 3) inlet point is arranged to the open type bell mouth shape, inlet point is increased, help material and enter smoothly; 4) the present invention further is arranged to the transportation section conical section and linear portion, and conical section is for material being formed extruding so that caking materials is pulverized, material can being moved normally; If but bore contracts when too small, transport efficiency is reduced, after so the bore of conical section of the present invention narrows down to a certain degree, become linear portion, this moment, caking materials was pulverized, so bore need not further to dwindle through the conveying of conical section, this moment, the transportation section became linear portion, guaranteed the transport efficiency of material; 5) the present invention is at the discharging opening flood gate of setting up defences, and establishes pressure sensor thereon, and when mass transport, sensor is to signal, and tide gate is opened, the material smooth delivery of power; After mass transport finished, sensor was closed tide gate to signal, and material and chemicals dosing plant are isolated, and prevented that extraneous moisture from making its caking by chemicals dosing plant recontamination material, influences the dosing quality; 6) conveying screw rod of the present invention is driven by worm reducer by inorganic variable-speed motor, and feed rate is regulated by the handwheel on the variable-speed motor, so just can according to circumstances adjust, and makes mass transport more effectively, carry out smoothly.
Description of drawings
1 is that inlet point, 2 is that conical section, 3 is that linear portion, 4 is that heating arrangement, 5 is that pressure sensor, 6 is tide gate among the figure.
The specific embodiment
The present invention includes inlet point 1, transportation section and the discharging opening of open type bell mouth shape, conveying screw rod is set in the transportation section, the connecting portion of transportation section and inlet point 1 is the cone-shaped that opening successively decreases gradually, and the transportation section is provided with heating arrangement 4; The transportation section comprises conical section 2 and linear portion 3, and conical section 2 and inlet point 1 engage, and linear portion 3 two ends engage with conical section 2, discharging opening respectively; The discharging opening place flood gate 6 of setting up defences is established pressure sensor 5 on the tide gate 6; Conveying screw rod is driven by worm reducer by inorganic variable-speed motor, and feed rate is regulated by the handwheel on the variable-speed motor.
Spacing equal difference between screw flight circle diameter of the present invention and screw thread reduces gradually, initial diameter is generally 250mm～600mm, and end diameter is generally 120mm～300mm, and the initial spacing between screw thread is generally 180mm～250mm, terminal spacing is generally 50mm～100mm, becomes the snail spiral.
Described heating arrangement 4 is arranged on the tube wall bottom of transportation section, can be the 36W infrared heater.
Can establish spring in tide gate 6 bottoms, play the effect that opens and closes tide gate 6.
Claims (5)
