Description of drawings
Fig. 1 is the structure drawing of device of the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, content and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.
The continuous feeding of the solid catalyst of the utility model embodiment comprises an integral frame (being to make the modular structural support of feeding device, not shown), and other parts of described device all are arranged in the described integral frame.The mode of this integral frame with parts such as storage bin, fluidising chamber, tube connector, weightless scale being arranged in the integral frame from top to bottom, is rationally utilized the space, and the connection of each parts simultaneously adopts flange to connect, and assurance device has good sealing property.
As shown in Figure 1, parts in the described integral frame comprise: storage bin 1, fluidising chamber 2, filter 3 and the weightless scale 6 that connects successively from top to bottom, connect by pipeline between described storage bin 1 and the fluidising chamber 2, connect by tube connector between described filter 3 and the weightless scale 6.Above-mentioned weightless scale is a kind of weighing-appliance that is interrupted feed, continuous discharging, because vector control is to carry out in the blanking hopper, can reach high control precision, and structure is easy to sealing again.The operation principle of weightless scale is based on the controlled loss in weight, when weight during less than upper weight limit and greater than lower weight limit, weightless scale is in weight-loss type batching state, the loss in weight in unit interval equals actual discharge flow, with the discharge flow of reality with set flow and compare and draw difference, in time adjust the feeding coal of removal device in the weightless scale, thereby make the withdrawal rate equilibrium.
Described tube connector comprises that one connects flexible pipe 5 and two Pneumatic butterfly valves 4, and described connection flexible pipe 5 is between two Pneumatic butterfly valves 4.
Described device also comprises the frequency conversion screw delivery pump 7 that is arranged at described weightless scale 6 belows.
