DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1-5 As shown, the utility model provides a polyurethane chain extender reaction device, including a reaction device body 1, which is suitable for use in polyurethane chain extender reactions. The reaction device body 1 includes a bearing base 2, a reaction kettle 3 is fixedly installed at the middle position of the top of the bearing base 2, a discharge port 4 is fixedly installed at the front bottom end of the reaction kettle 3, a filter unit is arranged inside the reaction kettle 3, an extrusion unit is arranged above the filter unit, the filter unit includes a clamping groove 31 arranged on the top of the shell of the reaction kettle 3, a filter barrel 32 is movably installed inside the reaction kettle 3, a speaker guide port 33 is fixedly installed on the top of the filter barrel 32, and connecting blocks 34 are fixedly installed on the outer surfaces of the speaker guide port 33, the connecting block 34 is movably clamped in the inside of the clamping groove 31, an electric telescopic column 35 is fixedly installed on the bottom end of the connecting block 34, and the bottom of the electric telescopic column 35 is fixedly installed on the top of the bearing base 2.

[0027] Furthermore, by pouring the raw materials into the interior of the reactor 3 and the filter barrel 32, the materials are filtered after the reaction treatment. The materials flow out along the mesh holes of the filter barrel 32 and are uniformly collected inside the reactor 3. The materials inside the reactor 3 gradually increase. At this time, the electric telescopic columns 35 on both sides are started, thereby driving the filter barrel 32 to gradually move upward, which is convenient for filtering the materials.

[0028] Example 2

[0029] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the extrusion unit includes a left vertical rod 21 fixedly installed on the left edge position of the top of the supporting base 2, a right vertical rod 22 fixedly installed on the right edge position of the top of the supporting base 2, a supporting top plate 23 fixedly installed on the top of the left vertical rod 21 and the right vertical rod 22, a transmission motor 24 fixedly installed on the top rear end of the support top plate 23, a transmission screw 25 fixedly installed on the output end of the transmission motor 24, the other end of the transmission screw 25 is rotatably installed on the top rear end position of the supporting base 2, a moving plate 26 is movably sleeved on the outer surface of the transmission screw 25, both sides of the front end of the moving plate 26 are slidably sleeved on the outer surfaces of the left vertical rod 21 and the right vertical rod 22, an extrusion rod 27 is fixedly installed on the bottom end of the moving plate 26, and an extrusion disk 28 is fixedly installed on the bottom end of the extrusion rod 27.

[0030] Furthermore, the transmission screw 25 is driven to rotate at a uniform speed through the output end of the transmission motor 24. When the transmission screw 25 rotates, the moving plate 26 on its outer surface gradually moves downward and slides on the outer surfaces of the left vertical rod 21 and the right vertical rod 22 to limit the position and prevent the movement from causing position displacement. At this time, the extrusion rod 27 pushes the extrusion plate 28 to move downward along the inner wall of the filter barrel 32. The push of the extrusion plate 28 generates an extrusion force, which brings thrust to the material inside the filter barrel 32, thereby increasing the filtration rate.

[0031] The working principle of the polyurethane chain extender reaction device is described in detail below.

[0032] like Figure 1-5As shown, when in use, the raw materials are poured into the interior of the reactor 3 and located inside the filter barrel 32. After the reaction treatment, the filter barrel 32 is used to filter the materials. The materials flow out along the mesh of the filter barrel 32 and are uniformly collected inside the reactor 3. The materials inside the reactor 3 gradually increase. At this time, the electric telescopic columns 35 on both sides are started, thereby driving the filter barrel 32 to gradually move upward, which is convenient for filtering the materials. The output end of the transmission motor 24 drives the transmission screw 25 to rotate at a uniform speed. When the transmission screw 25 rotates, the moving plate 26 on its outer surface is gradually moved downward and slid on the outer surfaces of the left vertical rod 21 and the right vertical rod 22 to limit the position to prevent the movement from causing position deviation. At this time, the extrusion rod 27 pushes the extrusion plate 28 to move downward along the inner wall of the filter barrel 32. The push of the extrusion plate 28 generates an extrusion force, which brings thrust to the material inside the filter barrel 32 and improves the filtration rate.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
