[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical, non-stirred polycondensation reactor, comprising a reactor body and a support mechanism for supporting the reactor body. The support mechanism includes a fixing ring, which is fixedly sleeved on the lower side of the outer circumferential wall of the reactor body. Three sets of supports are provided equidistantly in a ring between the bottom end of the fixing ring and the bottom of the reactor body. Each support includes an outer connecting seat, an inner connecting seat, and a support screw. The outer connecting seat is fixedly connected to the bottom end of the fixing ring, and a support leg is rotatably connected to the outer connecting seat. The inner connecting seat is fixedly connected to the bottom of the reactor body. An upper connecting head is rotatably connected to the top end of the support screw, and the upper connecting head is rotatably connected to the inner connecting seat. An adjusting nut is fixedly sleeved on the outer wall of the support screw near the upper connecting head. A threaded sleeve is screwed onto the support screw, and a lower connecting head is fixedly connected to the bottom end of the threaded sleeve. A lower connecting seat is fixedly connected to the inner side wall of the support leg, and the lower connecting head is rotatably connected to the lower connecting seat.

[0007] Preferably, the bottom of the reactor body is fixedly connected with three sets of hinge seats at equal intervals in a ring. Each of the three sets of hinge seats is rotatably connected with a connecting rod. The bottom ends of the three sets of connecting rods are fixedly connected to guide shafts on both sides. Each of the three sets of support legs is provided with a clearance groove. The sides of the support legs are provided with guide grooves that communicate with the clearance grooves. The bottom ends of the three sets of connecting rods are movably installed in the clearance grooves of the three sets of support legs through the cooperation of the guide shafts and guide grooves.

Detailed Implementation

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] Example

[0020] Please see Figures 1-5 This utility model discloses a vertical, non-stirred polycondensation reactor, comprising a reactor body 1 and a fixing ring 2. The fixing ring 2 is fixedly sleeved on the lower side of the outer circumference of the reactor body 1. Three sets of supports are equidistantly arranged in a ring between the bottom end of the fixing ring 2 and the bottom of the reactor body 1. Each support includes an outer connecting seat 3, an inner connecting seat 5, and a supporting screw 6. The outer connecting seat 3 is fixedly connected to the bottom end of the fixing ring 2, and a supporting leg 4 is rotatably connected to the outer connecting seat 3. The inner connecting seat 5 is fixedly connected to the bottom of the reactor body 1. An upper connecting head 7 is rotatably connected to the top end of the supporting screw 6, and the upper connecting head 7 is rotatably connected to the inner connecting seat 5. An adjusting nut 8 is fixedly sleeved on the outer wall of the supporting screw 6 near the upper connecting head 7. A threaded sleeve 9 is screwed onto the supporting screw 6, and a lower connecting head 9 is fixedly connected to the bottom end of the threaded sleeve 9. The head 10 and the inner wall of the support leg 4 are fixedly connected to the lower connecting seat 11. The lower connecting head 10 and the lower connecting seat 11 are rotatably connected. In use, the three sets of support legs 4 distributed equidistantly in a ring at the bottom of the fixing ring 2 can support the reactor body 1. The support screw 6 can be rotated by adjusting the nut 8 with a wrench. Under the engagement of the thread, the threaded sleeve 9 can be driven to move downward along the support screw 6. The threaded sleeve 9 drives the support leg 4 to rotate outward through the engagement of the lower connecting head 10 and the lower connecting seat 11. In this way, the support leg 4 can be adjusted individually according to the flatness of the ground to ensure that the reactor body 1 is placed stably. The support range of the support leg 4 can also be adjusted by rotating the support leg 4 outward, thereby providing stable support for the reactor and improving the stability of the reactor when it is placed.

[0021] The reactor body 1 has three sets of hinge seats 13 fixedly connected at equal intervals in a ring at its bottom. Each of the three sets of hinge seats 13 is rotatably connected to a connecting rod 12. Each of the three sets of connecting rods 12 has a guide shaft 14 fixedly connected to both sides at its bottom end. Each of the three sets of support legs 4 has a clearance groove. Each of the two sides of the support leg 4 has a guide groove communicating with the clearance groove. The bottom ends of the three sets of connecting rods 12 are movably installed in the clearance grooves of the three sets of support legs 4 through the cooperation of the guide shaft 14 and the guide groove. When the threaded sleeve 9 pushes the support leg 4 to rotate outward, the support leg 4 pulls the connecting rod 12 to rotate outward through the guide shaft 14. The connecting rod 12 pulls the guide shaft 14 to slide upward along the guide groove. The cooperation of the guide shaft 14 and the guide groove limits the outward rotation of the support leg 4, thereby effectively preventing the threaded sleeve 9 from disengaging from the support screw 6.

[0022] The bottom ends of the three sets of support legs 4 are all fixedly connected with anti-slip rubber pads 15; by setting anti-slip rubber pads 15, the support legs 4 can avoid slipping when supporting the ground.

[0023] The top of the fixing ring 2 is fixedly connected to the outer wall of the reactor body 1 by three sets of ribs 16 at equal intervals in a ring; by setting the ribs 16, the connection between the fixing ring 2 and the reactor body 1 can be made more firm and stable.

[0024] All three sets of support legs 4 have rounded corners 17 at the bottom outer corners; by setting rounded corners 17, the stress at the bottom corners of the support legs 4 can be eliminated, and the structural strength of the support legs 4 can be improved.

[0025] This utility model discloses a vertical, non-stirred polycondensation reactor. In operation, three sets of equidistantly distributed support legs 4 at the bottom of the fixing ring 2 support the reactor body 1. A wrench is used to rotate the support screw 6 via the adjusting nut 8. This, in conjunction with the threaded connection, moves the threaded sleeve 9 downwards along the support screw 6. The threaded sleeve 9, through the engagement of the lower connector 10 and the lower connecting seat 11, causes the support legs 4 to rotate outwards. This allows for individual adjustment of the support legs 4 according to the flatness of the ground, ensuring the reactor body 1 is placed stably. The support range of the support legs 4 can also be adjusted by rotating them outwards, ensuring the reactor body 1 is placed stably. It should be noted that the reactor body 1 in this utility model is based on a reaction device for polyester production, as disclosed in patent publication number CN203061187U. This is prior art, and its specific structure and working principle have been described in detail in that patent publication; therefore, further elaboration is not required here.

[0026] The vertical unstirred polycondensation reactor of this utility model can be installed, connected or set up in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effects.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
