Specific embodiment

Below in conjunction with the accompanying drawings and embodiment the invention will be further described.

As depicted in figs. 1 and 2, the present invention includes rack 1, and shell 2 is fixedly installed in rack 1, is provided with circle on shell 2 The material channel of tubular, one end of material channel is provided with feed inlet 6, the other end is provided with discharge port 7, installation in material channel There is the shaft 4 being coaxially arranged, shaft 4 arranges that shaft 4 is equipped with for driving its turn along the length direction of material channel Dynamic driving device 3, shaft 4 are located at the position in material channel and 4 outer surface of shaft are provided with helical blade 5, helical blade 5 The outer surface of 7 side of discharge port is provided with striking sheet 10, striking sheet 10 along helical blade 5 hand of spiral interval cloth It sets, feed inlet 6 and discharge port 7 have been separately equipped with dust gathering arrester, and dust gathering arrester is all connected to negative-pressure pipeline 9.By by 5 He of helical blade The crushing cutter that striking sheet 10 forms is crushed fluorescence lamp lens, and using between material and material and shaft, broken The extrusion friction effect generated between cutter, shell, removes the mercurous fluorescent powder on fluorescence lamp lens.The meeting in shattering process A large amount of mercurous fluorescent powder dust are generated, the present invention is all connected with negative-pressure pipeline 9 in feed inlet 6 and discharge port 7, can make removing Mercurous fluorescent powder is recovered by negative-pressure pipeline 9.

Material channel in the present invention preferably uses tilt layout, and feed inlet 6 is located at the lower of material channel End, discharge port 7 be located at the eminence end of material channel, and under the effect of gravity, material towards 6 side of feed inlet with sliding downwards Trend, to realize secondary desorption, guarantees the desorption efficiency of fluorescent powder to better play extrusion friction effect.

The preferred arrangement of striking sheet 10 are as follows: along the hand of spiral of helical blade 5, striking sheet 10 divides for multiple sections Section, the arragement construction of each segment is that the arrangement spacing of striking sheet 10 is stepped up towards the direction of discharge port, using the cloth Mode is set, can effectively ensure that the broken ultimate size of material meets design requirement, so that fluorescent powder be enable more fully to be desorbed. In the present embodiment, the spacing between striking sheet 10 is stepped up, every to increase by one piece of spacing increase 1mm, when spacing reaches material After broken partial size demand, initial spacing is returned to, repeats the spacing of early period, it is ensured that material particular diameter entirely reaches 3mm-5mm, works as distance When discharge end 1m or so, striking sheet 10 can be no longer installed.Mode and the fixed company of helical blade 5 of welding can be used in striking sheet 10 It connects.

To make rotational structure more reliable, the both ends of shaft 4 are mounted on shell 2 by bearing and bearing block.Shaft 4 exists In material shattering process, higher temperature can be generated, to improve crushing efficiency and service life of equipment, the present invention is arranged in bearing block There is cooling water cavity, cooling water cavity is connected with water inlet pipe 11 and outlet pipe 12, and water inlet pipe 11 is connected by water pump and cooling water tank 8 It connects, outlet pipe 12 is connect with cooling water tank 8, is cooled down by the chilled(cooling) water return (CWR) of bearing block to bearing, and pass through nature Cooling is utilized recirculated water constantly.To improve cooling effect, the arrangement of chilled(cooling) water return (CWR) is that water inlet pipe 11 is connected to cold But water chamber bottom, outlet pipe 12 are connected at the top of cooling water cavity.

The inner wall of material channel has lining item along the length direction arranged for interval of material channel, and lining item is set to material channel Lower half and along the circle of material channel circumferentially.It is disposed with three semicircular lining items in the present embodiment, is uniformly distributed In the lower semicircular face of 2 inner wall of shell.After setting lining item, it can give material certain storage space in desorption process, keep away Exempt from material unity.

The invention also includes control system, driving device 3 is motor, is provided in control system for controlling motor speed Frequency converter.It can be according to the revolving speed of productivity and fluorescent lamp glass breaking partial size adjustment shaft 4.

The course of work of the invention is as follows: starting control system first starts the driving device 3 and cooling device of shaft 4, And the revolving speed of partial size adjustment shaft 4 is crushed according to productivity and old and useless fluorescent lamp；Old and useless fluorescent lamp is put into from feed inlet 6, when After old and useless fluorescent lamp enters 2 inside of shell, be rotated in crushing cutter crush, and using between fluorescence lamp lens and glimmering Light lamp lens and shaft 4, crushing cutter, the extrusion friction generated between shell 2 act on, and make the mercurous fluorescent powder on fluorescent glass Removing, mercurous fluorescent powder are recovered by negative-pressure pipeline 9, and glass then passes through discharge port 7 and is recovered in jumbo bag.
