Description of drawings
Fig. 1 is the structural representation of the blast drier for injection raw material of the present utility model; In figure, 1: casing; 11: upper box; 12: lower box; 2: air supply duct; 3: air-blast device; 4: exhaust duct; 5: cover plate; 6: buckling piece; 7: discharge pipe.
The specific embodiment
Below in conjunction with accompanying drawing, the blast drier for injection raw material of the present utility model is described in further detail.
By the structural representation of as shown in Figure 1 the blast drier that is used for injection raw material as can be known, this blast drier is installed on base, comprise casing 1, be arranged at casing 1 bottom discharging opening, be connected in the air supply duct 2 of casing 1 bottom sidewall and be arranged on the exhaust duct 4 on casing 1 top.
When blast drier carried out injection raw material dry, the first plate made discharge pipe 7 closures, and at this moment, injection raw material can not fall, and dry run is carried out; In the process that drying is carried out, in order to obtain the drying regime of injection raw material, then the sealing branch pipe(tube) is regulated the first plate discharging opening is communicated with branch pipe(tube), a small amount of injection raw material falls into branch pipe(tube), regulating the first plate, the path of closed discharging opening and branch pipe(tube) is opened the second plate, connect sample analysis, some dry degree are defective, continue drying, otherwise drying completed; After drying is completed, regulate the first plate discharging opening is communicated with trunk line, collect dried injection raw material.
The sidewall of lower box 12 has gas feed, and an end of air supply duct 2 is connected on gas vent, and an other end connects air-blast device 3, and for saving the space, this intake stack is vertically arranged.Because gas feed is oriented horizontal direction, for the intake stack that makes vertical layout can match with this gas feed, both connect by union elbow.Simultaneously, make in order to prevent drying, injection raw material pours in down a chimney and feeds subtube, covers one deck breathable cloth at the contact-making surface of air supply duct 2 and union elbow, and this breathable cloth can prevent that injection raw material from entering air supply duct 2 when allowing other to enter casing 1.
Air-blast device 3 adopts centrifugal blower, and the delivery outlet of centrifugal blower is connected with the import of air supply duct 2, and centrifugal blower also is connected with control panel (not shown in FIG.), can regulate by control panel the power of centrifugal blower; Simultaneously, in order to monitor the gas flow rate in air supply duct 2, in air supply duct 2, flowmeter is installed, regulates at any time the power of centrifugal blower according to the reading of flowmeter.
Be surrounded by heating jacket on the surface of air supply duct 2, this heating jacket also is connected with control panel, controls the power of heating jacket by control panel, makes the temperature of the gas in air supply duct 2 be in a suitable scope, thereby reaches higher drying efficiency.Wherein, the length of air supply duct 2 is 0.5～1m.
In present embodiment, because lower box 12 is hollow rounding bench-type, the diameter in cross section enlarges from the bottom up gradually, therefore, the gas that enters from air supply duct 2 has a process of diffusion gradually, and such structure is conducive to gas dispersion to each position of casing 1.
The upper box 11 of this blast drier is cylinder type, the contact portion of upper box 11 and lower box 12 is coincide mutually, one side and the upper box 11 of lower box 12 are hinged, opposite side kinge-joint knot component 6, this buckling piece 6 is a screw rod and is set on a nut on screw rod, and upper box 11 is provided with the hole clipping that matches with this screw rod.Drying is that screw rod inserts hole clipping, keeps the cooperation of upper box 11 and lower box 12; After drying is completed, when need to clear up casing 1, screw rod is withdrawed from hole clipping, upset upper box 11 can be cleared up.
Be hinged with cover plate 5 at the top of upper box 11, offer gas vent on cover plate 5, exhaust duct 4 is connected with this gas vent, and in order to prevent in dry run, dust falls into casing 1 inside, and exhaust duct 4 is arranged to case of bending.
The above-described specific embodiment has been described in detail the technical solution of the utility model and beneficial effect; be understood that the above only is most preferred embodiment of the present utility model; be not limited to the utility model; all any modifications of making in principle scope of the present utility model, replenish and be equal to replacement etc., within all should being included in protection domain of the present utility model.
