Abstract
The utility model provides a feeder of a dilute phase pneumatic conveying system, which comprises three portions of an air supply pipe, a feeding pipe and a material pipe, wherein the central shaft of the air supply pipe and the central shaft of the material pipe are coaxial, the central shaft of the feeding pipe is perpendicular to and intersected with the central shafts of the air supply pipe and the material pipe to form a triplet, the diameter of the air supply pipe is gradually reduced from the middle portion of the air supply pipe to the connecting portion of the triplet; the diameter of the material pipe is gradually increased from the connecting portion of the triplet to the middle portion of the material pipe; the diameter of the feeding pipe is gradually reduced from the flange of an air-closed valve to the connecting portion of the triplet, thereby the pressure difference between the feeding pipe and an air flow passage is enlarged, and materials can smoothly enter into the material pipe from the feeding pipe and then enter into the production system. The feeder of the utility model can completely prevent the material dust from escaping, the production environment pollution and the resource waste can not appear, the material yield rate and the productivity are enhanced, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of feed appliance, the feed appliance of the dilute phase air-transport system on especially a kind of titanium white production line.
Background technology
Present domestic general feed appliance, in particular for the feed appliance of titanium dioxide dilute phase air-transport system, most of employing mono-negative pressure method feeding or positive platen press feeding.Negative pressure method feed appliance is by blast pipe, materail tube, feed bin, compositions such as inlet point, blast pipe is shrink gradually round table-like from outside to inside, serrated end partly enters materail tube, during the blower fan air-supply, air-flow is certain speed and flows in the air channel that blast pipe and materail tube form, form the difference of pressure of pipeline and feed bin thus, difference of pressure and drive material and enter materail tube thus, enter production system, but because the speed of the throat-fed of feed bin changes, therefore often material blocks in the generation of negative pressure mouth, and then produces from inlet point effusion material dust, forms production environment and pollutes and the wasting of resources.The malleation feed system is connected by blast pipe, materail tube, feed pipe straight tee (ST.TEE), establishes on the feed pipe and closes air-valve, and material enters in the pipeline through feed pipe by closing air-valve, and the air-flow of being sent into by blast pipe is pressed in the materail tube, enters production system.But owing to there is air-flow to overflow in the feed pipe, therefore same inlet point can produce the material dust and overflow, and forms production environment and pollutes, because material is overflowed, makes the material yield reduce simultaneously, and production capacity descends, and then produces the raising of cost.
The utility model content
The purpose of this utility model is this technological deficiency that exists in the present titanium white production system, a kind of feed appliance of dilute phase air-transport system is provided, overflow to solve the material dust that exists in the prior art, produce production environment and pollute and the wasting of resources, the defective that the material yield is low, production capacity descends, cost improves.
The utility model is to realize by following technical scheme:
Feed appliance of the present utility model, form by blast pipe, feed pipe, materail tube three parts, the center shaft of described blast pipe and the spigot shaft coaxle of materail tube, the center shaft of described feed pipe is vertical and meet at the center shaft of blast pipe and materail tube, forms a threeway;
Described blast pipe one end is connected with the supply ventilating fan flange, and the other end and threeway are joined, and by blast pipe middle part to the threeway junction, the caliber of blast pipe progressively dwindles;
Described materail tube one end and threeway are joined, and the other end is connected with the production system flange, and by the threeway junction to materail tube middle part, the caliber of materail tube progressively enlarges;
Described feed pipe one end with close the air-valve flange and be connected, the other end and threeway are joined, and by closing air-valve flange place to the threeway junction, the caliber of feed pipe progressively dwindles.The described air-valve that closes is the high-precision air-valve that closes.
The beneficial effect of the feed appliance of dilute phase air-transport system of the present utility model is: stopped the material dust and overflowed, can not produce production environment and pollute and the wasting of resources, improved the material yield, improve production capacity, reduce production costs.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further elaborated explanation.
Relatively we are as can be seen from the constructional drawing of Fig. 3 and Fig. 1, feed system shown in Figure 2, feed appliance of the present utility model, form by blast pipe 1, feed pipe 2, materail tube 4 three parts, the spigot shaft coaxle of the center shaft of described blast pipe 1 and materail tube 4, the center shaft of described feed pipe 2 is vertical and meet at the center shaft of blast pipe 1 and materail tube 4, forms a threeway junction 3;
Described blast pipe 1 one ends are connected with the supply ventilating fan flange, and the other end and threeway junction 3 join, and by blast pipe 1 middle part to threeway junction 3, the caliber of blast pipe 1 progressively dwindles;
Described materail tube 4 one ends and threeway junction 3 join, and the other end is connected with the production system flange, and by threeway junction 3 to materail tube 4 middle parts, the caliber of materail tube 4 progressively enlarges;
Described feed pipe 2 one ends with close the air-valve flange and be connected, the other end and threeway junction 3 join, and by closing air-valve flange place to threeway junction 3, the caliber of feed pipe 2 progressively dwindles, the described air-valve that closes is the high-precision air-valve that closes.
Feed appliance of the present utility model, because blast pipe 1 middle part to threeway junction 3 blast pipe diameters are received little gradually, and threeway junction 3 to materail tube 4 middle parts, the caliber of materail tube 4 progressively enlarges, ducted air-flow velocity changes at the threeway connecting portion, air-flow velocity is slack-off by accelerating slowly again, simultaneously, feed pipe from close the air-valve flange to the caliber of threeway junction also be progressively receive little, material has also produced the variation of speed in this pipe, so feed pipe and blast pipe, it is negative pressure that materail tube produces a feed pipe and materail tube and difference of pressure in the intersection of these three pipelines, and this negative pressure makes the inflow of material more smooth and easy greater than the negative pressure that the prior art feed system produces, material negative pressure is thus brought in the materail tube, after entering materail tube, the malleation that is produced by air-flow is pressed into and enters in the production system, has avoided the material effusion.Feed appliance of the present utility model has been stopped the material dust and has been overflowed, and can not produce production environment and pollute and the wasting of resources, improves the material yield, improves production capacity, reduces production costs.
Of the present utility model being described of below becoming a partner in conjunction with the accompanying drawings, but the utility model is not limited to the foregoing description, this area those skilled in the art the distortion made according to the utility model, all drop within the protection domain of the present utility model.
