Abstract
The utility model provides a solid material conveying device, which comprises at least a conical hopper; the conical hopper comprises an upper feeding segment and a lower discharging segment; blades are arranged in the lower discharging segment; the blades are fixed without moving; certain gaps are formed between the blades and the internal wall of the lower discharging segment; the external wall of the lower discharging segment is connected with a bearing transmission device; and the lower discharging segment is driven to rotate by the bearing transmission device. The equipment provided by the utility model is capable of improving anti-blocking efficiency and reducing energy consumption.
Description
Technical field
The utility model belongs to the solid material transportation art, is specifically related to have the solid material load transfer device of intelligent block clearing and/or choke preventing function, particularly a kind of solid material load transfer device that when carrying along gravitational field, has intelligent block clearing and/or choke preventing function.
Background technology
At present, the solid material conveying is very general process in chemical industry, field of boilers, and wherein the vertical transport of solid material is modal process.In general, carrying for saving in energy along the solid material of gravitational field, all is to rely on gravity to carry out freely descending of solid material to carry.Solid material load transfer device along gravitational field comprises at least one broach hopper, and this broach hopper comprises top material loading section and bottom blanking section.Though the outlet size of blanking section much larger than the particle diameter of powder, still might form bridge formation when the discharging downwards of solid material integral body.This obstruction can cause the fault of load transfer device, and then has influence on the fault of total system.The major cause that results in blockage is such as having friction force between solid material and the equipment inwall, having friction force etc. between the solid material.In order to prevent latch up phenomenon, corresponding block clearing and/or anti-block apparatus must be set in load transfer device.
For many years, in order to solve blockage problem, developed vibration or beaten methods such as inwall, rotation scraping inwall, gas injection inwall.200810140442.0 proposed the equipment of rotary conic hopper stationary blade; 201020262144.1 proposed the fixedly equipment of broach hopper of rotating blade; Though these two kinds of equipment can reach the effect that prevents to stop up; But its energy consumption that prevents to stop up needs still need a kind ofly prevent the solid material load transfer device that stops up efficiently all than higher.
Summary of the invention
Blockage problem when carrying in order to solve solid material, the design people provides a kind of solid-handling equipment and method with block clearing and/or choke preventing function.
The solid-handling equipment that the utility model proposed; It comprises at least one broach hopper, and this broach hopper comprises top material loading section and bottom blanking section, has blade in the bottom blanking section; Vanes fixed is motionless; Blade and bottom blanking section inwall have a fixed gap, and bottom blanking section outer wall is connected with the bearing driving device, drive bottom blanking section through the bearing driving device and rotate.
Wherein, at least one blade, be connected with pressure sensor, preferably on each blade, be connected with pressure sensor.
Wherein, the space of blade and bottom blanking section inwall accounts for the 0.3-10% of bottom blanking section inwall radius, preferred 1.0%-6.6%, more preferably 1.6%-3.3%.
Wherein, blade is identical everywhere with the space of bottom blanking section inwall, and perhaps the space of blade and bottom blanking section inwall reduces from top to bottom gradually.
Wherein, blade plan form shape, straight tabular or swash plate shape in the shape of a spiral.
Wherein, the outlet section of blanking section has flow measurement in the bottom.
The flow that measures when flow measurement drops to when a certain amount of, starts the bearing driving device; Also can start the bearing driving device all the time.
In real-world operation; Resistance between blade and the solid material is very big, and vanes regular meeting problem such as become flexible, break off, come off is in case the problems referred to above take place; Not only can cause blocking-proof result obviously to descend; Also possibly damage parts such as hopper, therefore must in time find the problems referred to above, and maintenance immediately.The utility model can detect the situation of blade in real time, thereby solve the problems referred to above through pressure sensor is set.
The weight of hopper is bigger, adopt as 200810140442.0 in gear transmission the time, the rotation of hopper can not be stablized, and often breaks down, this equipment changes gear transmission into the bearing transmission, has overcome the gear transmission problem moved of normal and stable for a long time.
In addition, the equipment of the utility model is provided with flow measurement, can be according to the flowrate variation situation, and the rotation of control hopper, thus can effectively reduce energy consumption.
Description of drawings
Fig. 1 representes the structural representation of this equipment.
The specific embodiment
This equipment is referring to Fig. 1.Its structure comprises: at least one broach hopper, this broach hopper comprise top material loading section 1 and bottom blanking section 2, have blade 4 in the bottom blanking section 2, and blade 4 is fixed, and blade and bottom blanking section 2 inwalls have a fixed gap.The outlet section of blanking section has flow measurement 5 in the bottom, and blade plan form is the swash plate shape.Bottom blanking section 2 middle part outer walls are connected with bearing driving device 3, rotate through bearing driving device 3 drive bottom blanking sections.On each blade 4, be connected with the pressure sensor (not shown in FIG.).
When carrying powder material, flow measurement 5 is measured flowrate variation, when flow drops to when a certain amount of, starts bearing driving device 3.Pressure sensor on the blade is worked all the time, becomes flexible, breaks off, comes off etc. when unusual if find blade, can report to the police, and as early as possible blade is repaired.
Embodiment 1:
With fine coal is example; When flow drop to normal discharge 70% the time start bearing driving device 3, the space of blade and bottom blanking section 2 inwalls accounts for 0.1%, 0.3%, 1.0%, 1.6%, 3.3%, 6.6%, 10%, 15% of bottom blanking section radius (internal diameter).Measure 95% the energy consumption that flow returns to normal discharge.Energy consumption with 0.3% is 1, calculates other ratiometric energy consumption, sees table 1.
| 0.1％ | 0.3％ | 1.0％ | 1.6％ | 3.3％ | 6.6％ | 10％ | 15％ | |
| Energy consumption | 100％ | 95％ | 80％ | 75％ | 90％ | ?105％ |
Wherein 0.1% space pressure sensor when testing is for the second time reported to the police, and loosening phenomenon takes place blade on inspection; 15% can't return to 95% of normal discharge.
The space of employing 3.3% blade warning and bottom blanking section do not occur and rotates unusually apart from contact running 1000 hours.
