Description
Technical Field
The invention relates to an environment-friendly ultra-wide intelligent rake tooth conveyor.
Background
Bagasse is a main byproduct of the sugar industry, is fibrous residue of sugarcane stems after sugarcane is crushed and sugarcane juice is extracted, belongs to one of agricultural solid wastes, is a renewable resource, and can produce 1 ton of bagasse every 1 ton of sucrose. Bagasse is currently commonly used as a boiler fuel. The method has the main advantages that the emission of the sulfur dioxide generated by the combustion of the sugarcane is low, and the emission of the flue gas can reach the standard only by using the water film dust remover. The bagasse power generation adopts a cogeneration mode, and the calorific value of 3.68 tons of bagasse is equal to that of 1 ton of standard coal.
For bagasse transportation, a belt conveyor or a buried scraper conveyor is generally adopted, and the belt conveyor or the buried scraper conveyor is used for transporting bagasse, so that the problem is that:
1) The content of bagasse ash is about 4%, the belt conveyor cannot be completely sealed, the dust emission phenomenon is serious, and the environmental assessment cannot pass.
2) Sugarcane grows in tropical conditions and the belt is extremely easy to harden and oxidize under high temperature conditions for years. The performance of the double belt is changed, and the belt conveyor is often deviated, so that the normal operation of equipment is affected.
3) The belt conveyor is divided into an upper layer and a lower layer, but the lower layer belt can not convey bagasse, namely has no double-layer conveying function and can not meet the process design requirement.
4) Depending on the process design, 6 discharges are required over a short distance (not more than 6 meters). The belt conveyor cannot realize short-distance multipoint simultaneous discharging.
5) Depending on the process design, multiple discharges must be uniformly discharged. The belt conveyor can not meet the process requirement.
6) According to the process design, the conveyor is required to realize center point discharging along the center line. The belt conveyor does not meet the requirement, and can only realize single-side or double-side discharging along the left side and the right side.
7) The belt conveyor cannot separate bagasse particles from bagasse chaff (i.e., bagasse ash).
8) At present, the maximum scale of the state is 4000 tons/day in a sugar mill, the conveying capacity of a selected conveyor is 400 cubic/hour, the water content required in the (3) strip is related to the granularity and viscosity of materials in the detailed description of the application range of the embedded scraper conveyor in the 242 th page of the manual for designing the conveying machinery selection of the state grade, and the conveyor can be loosened to the degree after being scattered by hands when being generally applied to kneading by hands; on the other hand, in tables 12 to 20 on pages 269 to 274 of the manual for design of transportation machine, there are 225 kinds of bulk materials which can be transported by a buried scraper conveyor, and bagasse is not contained in the series of bulk materials. The bagasse has bulk density of 0.12-0.15t/m < 3 >, water content of 30%, extremely poor fluidity, strong viscosity and easy caking, so that the buried scraper conveyor is not suitable for conveying bagasse.

As shown in fig. 6 and 7, the head 4 includes a head housing 47, a head shaft 42 installed in the head housing 47, and a chain breakage protector (not shown in the chain breakage protector drawing), which may be an SCD stall switch, two head wheels 43 are installed on the head shaft 42, two conveyor chains 7 are installed on the two head wheels 43, the head shaft 42 is respectively connected to the two couplings 11, and a recovery surge bin 44 is communicated with the lower end of the head housing 47.
A recovery buffer level gauge 45 is installed in the recovery buffer bin 44, a clear material conveyor 46 is arranged below the recovery buffer bin 44, the recovery buffer level gauge 45 transmits a monitored signal to a controller, and the controller controls the clear material conveyor 46. A step of
Bagasse is unlikely to be completely unloaded in each discharge pipe, and a small portion of bagasse is carried to the head 4 recovery surge bin 44. When the accumulated materials exceed the high position of the recovery buffer level gauge 45, the controller automatically starts the material cleaning conveyor 46 to convey bagasse in the recovery buffer bin 44 away; when the accumulation is below the low level of the recovery buffer level gauge 45, the controller turns off the purge conveyor 46 to avoid bagasse that accumulates in the head from clogging moving parts in the head.
The driving units 1 are two, the two driving units 1 are respectively connected with the two couplings 11, the driving units 1 comprise variable frequency motors 12, speed reducers 13 and audible and visual alarms, and the controller controls the audible and visual alarms and the two variable frequency motors 12.
The driving units 1 are two, one is used and the other is used, when one set of driving units 1 which is normally used fails, the controller automatically starts the standby driving units 1, so that the continuous operation of the conveyor for 24 hours per day can be ensured, and after the failure occurs, a failure signal can be transmitted to an operator through the audible and visual alarm.
As shown in fig. 16, the tail 2 includes a tail housing 25, and a tension pulley 23 and a ranging sensor 24 for monitoring the height of 7 conveyor chains are installed in the tail housing 25, and the ranging sensor 24 transmits the monitored signal to the PLC controller. The distance measuring sensor 24 is used to monitor the chain tension and ensure the safety of the conveyor when running.
As shown in fig. 17, the number of teeth of the head gear 43 is greater than 15. The common buried scraper conveyor has the common tooth number of 8-12, and the tooth number of the head wheel 43 of the patent is more than 15 teeth, so that the running stability of the equipment is improved and the noise emitted by the head wheel 43 is reduced.
A chain removing wheel 48 is arranged in the head shell 47, and the top end of the chain removing wheel 48 is higher than a scraper chain guide rail of the conveyor, so that a chain removing function can be automatically realized; since the sprocket 48 does not contact the head pulley 43, it is possible to avoid wearing the head pulley 43 and to prevent the blade chain from "riding up".
The width of the middle section is larger than 3000mm, the height is larger than 700mm, the cross sections of the feeding channel and the discharging channel are in a convex shape, and the two guide rails are arranged on waistcoats on two sides of the convex structure. The embedded scraper conveyor is specified in national standard JB/T10596-2011 that the maximum width of a common embedded scraper conveyor groove is 1250mm, the maximum height of a bearing groove is 700mm, and the width is more than 3000mm and the height is more than 700mm, so that the conveyor with the size is particularly suitable for conveying fluffy light materials such as bagasse and wood dust.
