Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane particle processing equipment, in particular to a polyurethane particle dust-free conveying equipment. Background Art

[0002] In the prior art, after the polyurethane particles are produced, the polyurethane particles are not sufficiently cooled, and the internal temperature is still high. The heat inside the polyurethane particles is gradually transferred to the outside, causing the surface temperature of the polyurethane particles to rise, increasing the viscosity, causing adjacent polyurethane particles to stick together into blocks, seriously affecting the granulation effect; and as the processing time increases, the air inside the conveying space will absorb the residual heat of the polyurethane particles, causing the air to heat up, thereby increasing the cooling time of the polyurethane particles, so that the collected polyurethane particles will still have the problem of sticking together. Utility Model Content

[0003] In order to overcome the disadvantage that the air inside the conveying space will absorb the residual heat of the polyurethane particles, causing the air to heat up and thus increasing the cooling time of the polyurethane particles, the utility model provides a dust-free conveying device for polyurethane particles.

[0004] Technical solution: A dust-free conveying device for polyurethane particles, including a conical frame; also including a motor, a conical column, convex strips, a feed pipe, a discharge pipe and an air conveying unit; the motor is fixedly connected to the left side of the conical frame; the conical column is fixedly connected to the rotating part of the motor; a plurality of convex strips are fixedly connected to the surface of the conical column; a plurality of feed pipes are fixedly connected to the upper part of the conical frame; a plurality of discharge pipes are fixedly connected to the bottom of the conical frame; the conical frame is connected to a plurality of air conveying units for conveying dust-free air into the conical frame.

[0005] In addition, it is particularly preferred that the air delivery unit includes a pump, a filter and an intake pipe; the pump is fixedly connected to the rear side of the conical frame; the pump is fixedly connected to and connected to the intake pipe, and the intake pipe is connected to the inside of the conical frame; the intake pipe is fixedly connected to and connected to the filter, and the filter is located between the pump and the intake pipe.

[0006] In addition, it is particularly preferred that the cooling unit includes a circulation pipe, a refrigeration circulator, a straight pipe, and a V-shaped plate; a plurality of refrigeration circulators are fixedly connected to the front side of the conical frame; each refrigeration circulator has an air outlet fixedly connected and connected to a straight pipe, and each straight pipe is connected to the interior of the conical frame; each refrigeration circulator has an air extraction end fixedly connected and connected to a circulation pipe, and the other end of each circulation pipe is connected to the corresponding air inlet pipe; a V-shaped plate is fixedly connected to the front side of the conical frame, a plurality of air outlets are opened on the V-shaped plate, and all the straight pipes are connected to the V-shaped plate.

[0007] Furthermore, it is particularly preferred that the air outlet is arranged obliquely upward.

[0008] Furthermore, it is particularly preferred that the V-shaped plate is provided with a chamfer.

[0009] In addition, it is particularly preferred that a baffle is also included; a plurality of baffles are fixedly connected to the V-shaped plate, all of the baffles fit the surface of the conical column, and all of the baffles are staggered with the convex strips.

[0010] Beneficial effect: The utility model starts the motor to drive the conical column and the convex strip to rotate clockwise from left to right. When the convex strip rotates, it will hit the polyurethane particles that fall into the surface of the conical column, so that the polyurethane particles that stick together are dispersed by the convex strip, avoiding the problem of the polyurethane particles sticking to each other and forming blocks.

[0011] The utility model starts the refrigeration circulator to draw air in the conical frame through the circulation pipe and cools the air, then sprays the cooled air from the straight pipe into the V-shaped plate, and sprays it back into the conical frame from the air outlet, so that the air in the conical frame is cooled down, and avoids the problem that as the processing time increases, the air inside the conveying space absorbs the residual heat of the polyurethane particles, causing the air to heat up, thereby increasing the cooling time of the polyurethane particles, and causing the collected polyurethane particles to still be clumped together.

[0012] The utility model sets the air outlet obliquely upward. When the refrigeration circulator transports the internal cold air from the straight pipe to the V-shaped plate and sprays it out from the air outlet, the cold air sprayed from the air outlet will blow on the surface of the tapered column and blow upward along the surface of the tapered column, so that the cold air contacts the polyurethane particles just extruded, thereby accelerating the cooling speed of the polyurethane particles.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] Example 1

[0021] A dust-free conveying device for polyurethane particles, such as Figure 1-Figure 5 As shown, it includes a tapered frame 1;

[0022] It also includes a motor 10, a conical column 11, a convex strip 12, a feed pipe 13, a discharge pipe 14 and an air conveying unit; the motor 10 is bolted to the left side of the conical frame 1; the conical column 11 is fixedly connected to the rotating part of the motor 10; a plurality of convex strips 12 are fixedly connected to the surface of the conical column 11; two feed pipes 13 that are symmetrical on the left and right are fixedly connected to the upper part of the conical frame 1; two discharge pipes 14 that are symmetrical on the left and right are fixedly connected to the bottom of the conical frame 1; and the conical frame 1 is connected to two air conveying units that are symmetrical on the left and right.

[0023] The air delivery unit includes a pump 3, a filter 4 and an intake pipe 2; the pump 3 is bolted to the rear side of the conical frame 1; the pump 3 is fixedly connected to and communicated with the intake pipe 2, and the intake pipe 2 is communicated with the inside of the conical frame 1; the intake pipe 2 is fixedly connected to and communicated with the filter 4, and the filter 4 is located between the pump 3 and the intake pipe 2.

[0024] The cooling unit includes a circulation pipe 5, a refrigeration circulator 6, a straight pipe 7, and a V-shaped plate 8; two symmetrical refrigeration circulators 6 are bolted to the front side of the conical frame 1; the air outlet end of each refrigeration circulator 6 is fixedly connected and connected to a straight pipe 7, and each straight pipe 7 is connected to the inside of the conical frame 1; the air suction end of each refrigeration circulator 6 is fixedly connected and connected to a circulation pipe 5, and the other end of each circulation pipe 5 is connected to the corresponding air inlet pipe 2; a V-shaped plate 8 is fixedly connected to the front side of the conical frame 1, and a plurality of air outlets 8a are opened on the V-shaped plate 8, and all the straight pipes 7 are connected to the V-shaped plate 8.

[0025] The air outlet 8a is arranged obliquely upward, and the internal cold air is transported from the straight pipe 7 to the V-shaped plate 8 through the refrigeration circulator 6. Then, when the cold air is ejected from the air outlet 8a, the cold air ejected from the air outlet 8a will blow on the surface of the conical column 11, and the cold air will be blown upward along the surface of the conical column 11, so that the cold air contacts the freshly extruded polyurethane particles, thereby accelerating the cooling speed of the polyurethane particles.

[0026] The V-shaped plate 8 is provided with an inclined surface 8 b, through which the polyurethane particles dropped onto the V-shaped plate 8 are guided downward, thereby preventing the polyurethane particles from remaining on the V-shaped plate 8 .

[0027] It also includes baffles 9; a plurality of baffles 9 are fixedly connected to the V-shaped plate 8, all of the baffles 9 are in contact with the surface of the conical column 11, and all of the baffles 9 are staggered with the convex strips 12.

[0028] Here is how the above example works:

[0029] First, the polyurethane granulator is connected to the feed pipe 13, and the pump 3, the filter 4, the refrigeration circulator 6 and the motor 10 are connected to the external power supply. Then, the pump 3 is started to suck the outside air, and the air is transported to the conical frame 1 through the air inlet pipe 2. When the pump 3 transports the air to the air inlet pipe 2, the air will first pass through the filter 4, and the dust in the air will be intercepted by the filter 4 to prevent the dust from adhering to the polyurethane particles and affecting the quality of the polyurethane particles.

[0030] Then, the polyurethane granulator is started to granulate, and the produced polyurethane granules fall from the feed pipe 13 onto the surface of the conical column 11. However, after the polyurethane granules are produced, the polyurethane granules are not fully cooled, and the internal temperature is still high. The heat inside the polyurethane granules is gradually transferred to the outside, which increases the surface temperature of the polyurethane granules and increases the viscosity, causing adjacent polyurethane granules to stick together into blocks, which seriously affects the granulation effect. Therefore, the motor 10 is started to drive the conical column 11 and the convex strip 12 to rotate clockwise from left to right. When the convex strip 12 rotates, it will hit the polyurethane granules that fall onto the surface of the conical column 11, so that the polyurethane granules that stick together are beaten apart by the convex strip 12, thereby avoiding the problem of the polyurethane granules sticking together into blocks.

[0031] However, as the processing time increases, the air inside the conveying space will absorb the residual heat of the polyurethane particles, causing the air temperature to rise, thereby increasing the cooling time of the polyurethane particles, so that the collected polyurethane particles will still have the problem of sticking together. Therefore, the refrigeration circulator 6 is started to suck the air in the conical frame 1 through the circulation pipe 5 and cool the air, and then the cooled air is sprayed from the straight pipe 7 to the V-shaped plate 8, and then sprayed back to the conical frame 1 from the air outlet 8a, so that the air in the conical frame 1 is cooled, thereby avoiding the problem that as the processing time increases, the air inside the conveying space absorbs the residual heat of the polyurethane particles, causing the air temperature to rise, thereby increasing the cooling time of the polyurethane particles, so that the collected polyurethane particles will still have the problem of sticking together.

[0032] At the same time, by arranging the air outlet 8a obliquely upward, when the refrigeration circulator 6 delivers the internal cold air from the straight pipe 7 to the V-shaped plate 8 and ejects it from the air outlet 8a, the cold air ejected from the air outlet 8a will blow on the surface of the conical column 11, and the cold air will blow upward along the surface of the conical column 11, so that the cold air contacts the polyurethane particles just extruded, thereby accelerating the cooling speed of the polyurethane particles;

[0033] At the same time, because there is a gap between two adjacent convex strips 12, some polyurethane particles are not hit by the convex strips 12, resulting in them still sticking together. Therefore, when the motor 10 drives the conical column 11 and the convex strips 12 to rotate and scatter the polyurethane particles, some polyurethane particles fall downward through the gap between two adjacent convex strips 12 and fall onto the baffle 9. Because there is friction between the conical column 11 and the polyurethane particles, the conical column 11 will drive the polyurethane particles on the surface to rotate at the same speed. Therefore, when the polyurethane particles contact the baffle 9, the polyurethane particles will collide with the baffle 9, so that the polyurethane particles stuck together will be scattered, avoiding the gap between two adjacent convex strips 12, resulting in some polyurethane particles not being hit by the convex strips 12, resulting in them still sticking together. At the same time, by providing the inclined surface 8b, the polyurethane particles will not remain on the V-shaped plate 8.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
