Description

Technical Field

[0001] This utility model relates to the field of catalyst tank technology, specifically to a discharge mechanism for polyolefin and rubber catalyst tanks. Background Technology

[0002] Polyolefins are thermoplastic resins obtained by polymerizing ethylene. They are odorless, non-toxic, and have a waxy feel. They have excellent low-temperature resistance, good chemical stability, and can withstand the corrosion of most acids and alkalis. Polyolefin catalysts are mainly transition metal compounds such as titanium that are chemically bonded to magnesium-containing supports. They have advantages such as high catalytic efficiency, good overall performance of the produced polymers, and low cost.

[0003] A search revealed that Chinese Patent Publication No. CN 222512477 U discloses a discharge mechanism for a polyolefin catalyst tank, comprising a base, a storage tank body, a discharge pipe, a pusher, a baffle, and a cleaning cotton. The storage tank body is fixedly installed at the top of the base, and the discharge pipe is fixedly connected and communicated with the bottom of the storage tank body. The bottom of the discharge pipe is fixedly connected and communicated with the discharge pipe. A connecting buckle is fixedly welded to the top of one end of the discharge pipe and is fixedly connected to the baffle. The pusher is laterally slidably connected to the opening at the other end of the discharge pipe, and the outer side of the pusher is fixedly connected to one end of a hydraulic cylinder. This application uses a pusher to clean catalyst residues in the discharge pipe, thereby reducing blockage and improving discharge efficiency.

[0004] The discharge mechanism in the aforementioned patent still has some shortcomings. Since most existing mixing tanks output materials through discharge pipes set at their bottom, and for polyolefin and rubber catalyst mixtures, which are mostly solid-liquid mixtures with a certain degree of viscosity, the discharge rate is slow when relying solely on gravity during the actual discharge process. Furthermore, some of the viscous mixture will adhere to the wall of the discharge pipe during the discharge process, which can easily cause accumulation and blockage, making it difficult to meet the user's discharge needs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a discharge mechanism for polyolefin and rubber catalyst tanks. This solves the problem that most existing mixing tanks discharge materials through a discharge pipe located at their bottom. However, for polyolefin and rubber catalyst mixtures, which are mostly viscous solid-liquid mixtures, the discharge rate is slow due to gravity alone. Furthermore, the viscous mixture tends to adhere to the discharge pipe wall during discharge, easily causing blockages and failing to meet user discharge requirements.

[0006] This utility model provides the following technical solution: a discharge mechanism for a polyolefin and rubber catalyst tank, comprising a storage tank, supporting legs evenly arranged around the bottom of the storage tank, a central transmission rod vertically arranged inside the storage tank, two mixing and stirring rods symmetrically arranged on both sides of the central transmission rod, the top end of the central transmission rod rotatably penetrating through the top of the storage tank, a drive motor installed on the top of the storage tank, the drive shaft of the drive motor being fixedly connected to the top end of the central transmission rod, a connecting bearing provided at the bottom end of the central transmission rod, the two sides of the connecting bearing being fixedly connected to the inner wall of the storage tank through a bearing fixing bracket, and a rapid discharge assembly provided at the bottom of the storage tank;

[0007] The rapid discharge assembly includes two discharge ports symmetrically located on both sides of the bottom of the storage tank. A push chamber is fixed to the outside of each discharge port. A drive connecting rod is rotatably installed inside the push chamber. An auger blade is fixed on the drive connecting rod. A servo motor is installed on the outside of the push chamber. The drive end of the servo motor passes through the push chamber and is fixedly connected to the end of the drive connecting rod. A discharge port is opened at the bottom of the side of the push chamber. A discharge pipe is installed on the discharge port. A first valve is installed on the discharge pipe.

[0008] Preferred technical solution 1: A feeding port is provided on the side of the top of the storage tank, and a sealing cover is provided on the feeding port.

[0009] Preferred technical solution 2: A cleaning drain pipe is provided in the middle of the bottom of the storage tank, and a second valve is provided on the cleaning drain pipe.

[0010] Preferred technical solution 3: The bottom of the storage tank is in the shape of an inverted cone.

[0011] This solution makes it easier for the mixed materials to be discharged later.

[0012] Preferred technical solution four: The servo motor and the push chamber are connected by a fixing plate.

[0013] This solution enables the servo motor to drive the connecting rod to rotate more stably.

[0014] Preferred technical solution five: The push chamber is arranged along the inclined outer wall of the bottom side of the storage tank.

[0015] This solution enables materials entering the push chamber through the discharge port to be discharged more effectively.

[0016] Compared with the prior art, this utility model provides a discharge mechanism for polyolefin and rubber catalyst tanks, which has the following advantages:

[0017] (1) This utility model has a fast discharge component at the bottom of the storage tank. The fast discharge component has a push chamber outside the discharge port. The mixed material at the bottom of the storage tank can enter the push chamber through the discharge port. The servo motor drives the auger blade to rotate through the drive connecting rod, so that the auger blade can push the viscous mixture that enters the push chamber and push it to the discharge port for discharge. The discharge process is faster and is not affected by the viscosity of the material. It can achieve timely and effective discharge and will not cause the material to stick to the pipe wall and cause blockage. Attached Figure Description

[0024] Please see Figure 1-4 ,

[0025] Example 1: A discharge mechanism for a polyolefin and rubber catalyst tank includes a storage tank 1. Support legs 2 are evenly arranged around the bottom of the storage tank 1. A central transmission rod 3 is vertically arranged inside the storage tank 1. Two mixing and stirring rods 4 are symmetrically arranged on both sides of the central transmission rod 3. The top of the central transmission rod 3 rotates through the top of the storage tank 1. A drive motor 5 is installed on the top of the storage tank 1.

[0026] The drive shaft of the drive motor 5 is fixedly connected to the top of the middle transmission rod 3. The bottom of the middle transmission rod 3 is provided with a connecting bearing 6. The two sides of the connecting bearing 6 are fixedly connected to the inner wall of the storage tank 1 through the provided bearing fixing bracket 7. The bottom of the storage tank 1 is provided with a fast discharge component 8. The top side of the storage tank 1 is provided with a feeding port 9. A sealing cover 10 is provided on the feeding port 9.

[0027] The rapid discharge assembly 8 includes two discharge ports 801 symmetrically located on both sides of the bottom of the storage tank 1. A push chamber 802 is fixed to the outside of each discharge port 801. A drive connecting rod 803 is rotatably installed inside the push chamber 802. An auger blade 804 is fixed on the drive connecting rod 803. A servo motor 805 is installed on the outside of the push chamber 802. The drive end of the servo motor 805 passes through the push chamber 802 and is fixedly connected to the end of the drive connecting rod 803. A discharge port 806 is opened at the bottom of the side of the push chamber 802. A discharge pipe 807 is installed on the discharge port 806. A first valve 808 is installed on the discharge pipe 807. A cleaning drain pipe 809 is installed in the middle of the bottom of the storage tank 1. A second valve 810 is installed on the cleaning drain pipe 809.

[0028] Example 2: The difference between this example and Example 1 is that the bottom of the storage tank 1 is in the shape of an inverted cone.

[0029] This makes it easier for the mixed materials to be discharged later.

[0030] Example 3: The difference between this example and Example 1 is that the servo motor 805 and the push chamber 802 are connected by a fixed plate.

[0031] This makes the rotation of the servo motor 805 driving the connecting rod 803 more stable.

[0032] Example 4: The difference between this example and Example 1 is that the push chamber 802 is arranged along the inclined outer wall of the bottom side of the storage tank 1.

[0033] This allows the material entering the push chamber 802 through the discharge port 801 to be discharged more effectively.

[0034] In this embodiment, since most existing mixing tanks output materials through discharge pipes at their bottom, and for polyolefin and rubber catalyst mixtures, which are mostly solid-liquid mixtures with a certain degree of viscosity, the discharge rate is slow when relying solely on gravity during the actual discharge process. Furthermore, some of the viscous mixture will adhere to the discharge pipe wall during the discharge process, which can easily cause accumulation and blockage, making it difficult to meet the user's discharge requirements.

[0035] In summary, in practical implementation, when the polyolefin and rubber catalyst materials added to the storage tank 1 through the feeding port 9 need to be mixed, the user starts the drive motor 5 by connecting an external power source. The drive motor 5 then drives the mixing rod 4 through the central transmission rod 3 to mix the materials entering the storage tank 1.

[0036] When users need to quickly discharge the mixed materials, and because the mixture of polyolefin and rubber catalyst has a certain viscosity, it will cause some blockage to the normal discharge pipe. However, by setting a rapid discharge component 8 at the bottom of the storage tank 1, a drive connecting rod 803 is rotatably set in the push chamber 802 of the rapid discharge component 8. An auger blade 804 is set on the drive connecting rod 803. The drive connecting rod 803 rotates under the drive of the servo motor 805, thereby pushing the mixture that enters the push chamber 802 through the discharge port 801 downward.

[0037] By opening the first valve 808 on the discharge pipe 807, the material entering the push chamber 802 is pushed by the screw conveyor blade 804 to the discharge port 806, and then discharged into the discharge pipe 807. Even if the polyolefin and rubber catalyst mixture is in an emulsified state, it can be discharged quickly without being limited by the viscosity of the mixture itself and causing blockage. Moreover, the overall discharge rate is faster and can meet the user's needs.
