Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials into a reaction kettle, in particular to a feeding device for a polyurethane polyol low-temperature reaction kettle. Background Art

[0002] Polyurethane polyol reactors ensure smooth reactions at low temperatures by controlling parameters such as reaction temperature, pressure, and stirring speed. These low-temperature polyurethane polyol reactors utilize advanced temperature control technologies, such as electric heating and a jacketed external circulation heating / cooling system, to precisely control the reaction temperature and ensure stable reactions at low temperatures. Depending on the specific model and specifications, the design temperature can reach up to 300°C, but the operating temperature is typically between -10°C and 250°C to meet the needs of low-temperature reactions.

[0003] When feeding materials into the existing reactor feeding device, the materials fed into the reactor are relatively concentrated, so that the materials are easily accumulated in the reactor, which slows down the reaction of polyurethane polyol, increases the reaction time, and ultimately reduces the production efficiency of polyurethane products. Utility Model Content

[0004] The purpose of the utility model is to provide a feeding device for a polyurethane polyol low-temperature reactor, which can feed materials into a feeding hopper, drive the spur gear to rotate through the output end of the driving motor, so that the spur gear can drive the gear ring and the rotating drum to rotate, and the rotating drum drives the rotating shaft and the spiral plate to rotate, so that the material can be transported to the vibrating drum through the spiral plate. When the material is transported to the conical part, the rotating drum slides through the limit groove and the sliding column, thereby also driving the vibrating drum to rotate, so that the material can be thrown into the reactor from a plurality of discharge holes annularly and equidistantly opened on the outer wall of the conical part. After the material can be uniformly fed into the reactor under the action of centrifugal force, it can prevent the material from accumulating and falling into the reactor, thereby helping to accelerate the reaction of polyurethane polyol and other materials and improve the production efficiency of polyurethane products.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The top end of the lifting pole is fixedly provided with the lifting pole of the lifting pole, and the bottom end of the lifting pole is fixedly provided with the lifting pole of the lifting pole.

[0007] Furthermore, a rotating shaft 1 is fixedly connected to the center of the rotating cylinder, and a spiral plate is fixedly connected to the outer wall of the rotating shaft 1.

[0008] Furthermore, an annular plate is fixedly sleeved on the outer wall of the vibration cylinder, and two arc-shaped inclined plane seats are symmetrically fixedly connected to the top of the annular plate.

[0009] Furthermore, a panel is fixedly connected to the top of the reactor, two positioning frames are symmetrically fixedly connected to the top of the panel, and rotating wheels are rotatably connected to the two positioning frames, and the rotating wheels are in sliding contact with the arc-shaped inclined seat.

[0010] Furthermore, a plurality of buffer springs fixedly connected to the rotating cylinder are equidistantly and annularly fixedly connected to the outer portion of the vibration cylinder.

[0011] Furthermore, a second rotating shaft is fixedly connected to the center of the bottom end of the conical portion, and a plurality of stirring blades are fixedly connected to the outer wall of the second rotating shaft at equal distances.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The material can be put into the feeding hopper, and the spur gear is driven to rotate by the output end of the driving motor, so that the spur gear can drive the gear ring and the rotating drum to rotate, and the rotating drum is used to drive the rotating shaft and the spiral plate to rotate, so that the material can be transported to the vibrating drum through the spiral plate. When the material is transported to the conical part, the rotating drum slides through the limit groove and the sliding column, thereby also driving the vibrating drum to rotate, so that the material can be thrown into the reactor from multiple discharge holes equidistantly arranged on the outer wall of the conical part. After the material can be evenly put into the reactor under the action of centrifugal force, it can prevent the material from accumulating and falling into the reactor, thereby helping to accelerate the reaction of polyurethane polyol and other materials and improve the production efficiency of polyurethane products.

[0014] 2. During the rotation of the vibrating cylinder, the two arc-shaped inclined seats on the annular plate and the rotating wheel will slide against each other, causing the vibrating cylinder to slide downward in the rotating cylinder, and then quickly reset under the pull of the buffer spring. Therefore, the vibrating cylinder and the tapered part can vibrate back and forth continuously, which can prevent the material from clogging the discharge hole during the conveying process and ensure the smooth feeding of the material.

A vibrating cylinder 111 is fixedly connected between the sliding columns 112. The bottom end of the vibrating cylinder 111 is fixedly connected with a conical portion 116, and a plurality of discharge holes 117 are provided on the outer wall of the conical portion 116 at equal intervals in a ring shape; a rotating shaft 109 is fixedly connected to the center position of the rotating cylinder 104, and a spiral plate 110 is fixedly connected to the outer wall of the rotating shaft 109.

[0023] Specifically, the material can be put into the feeding hopper 101, and the output end of the driving motor 107 drives the spur gear 106 to rotate, so that the spur gear 106 can drive the gear ring 105 and the rotating cylinder 104 to rotate, and the rotating cylinder 104 drives the rotating shaft 109 and the spiral plate 110 to rotate, so that the material can be transported to the vibrating cylinder 111 through the spiral plate 110. When the material is transported to the conical portion 116, the rotating cylinder 104 slides through the limiting groove 108 and the sliding column 112, thereby also driving the vibrating cylinder 111 to rotate, so that the material can be thrown into the reactor 201 from the multiple discharge holes 117 annularly and equidistantly opened on the outer wall of the conical portion 116.

Therefore, the vibrating cylinder 111 and the conical portion 116 can vibrate back and forth continuously, thereby preventing the material from clogging the discharge hole 117 during the conveying process, thereby ensuring the smooth feeding of the material.
