Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically a feeding device for a corrosion-resistant EPS reactor. Background Technology

[0002] In the field of EPS (polystyrene foam) production, the efficient and stable operation of the reactor feeding process plays a decisive role in the overall production quality and efficiency. Currently, the feeding devices commonly used in the industry have many shortcomings. Traditional feeding devices are mostly single-channel structures, making it difficult to achieve simultaneous feeding when processing multiple raw materials. When preparing EPS products with flame-retardant properties, multiple raw materials such as polystyrene particles, foaming agents, and flame retardants need to be added simultaneously. However, existing devices often can only feed these materials sequentially. This not only significantly lengthens the production cycle but also easily leads to poor product quality due to differences in mixing time between raw materials entering the reactor at different times.

[0003] To address the above problems, this utility model proposes a corrosion-resistant EPS reactor feeding device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of existing devices that can only feed materials sequentially, which not only greatly extends the production cycle, but also causes the raw materials entering the reactor at different times to have different mixing times. This utility model proposes a corrosion-resistant EPS reactor feeding device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a corrosion-resistant EPS reactor feeding device, including a feeding assembly disposed on the upper end of the reactor body, wherein multiple sets of feeding assemblies are provided, and the multiple sets of feeding assemblies are evenly distributed around the outer wall of the reactor body. Each feeding assembly includes an outer frame fixedly connected to the outer wall of the reactor body, an electric push rod is installed in the cavity of the outer frame, and a storage tank is shaft-connected to the output end of the electric push rod. One end of the storage tank rests on the upper wall of the reactor body, and the connection between the output end of the electric push rod and the storage tank is away from the contact surface between the storage tank and the reactor body.

[0006] The upper wall of the storage box is provided with a feeding groove, the inner wall of the storage box is fixedly connected with an installation plate, and the outer wall of the installation plate is provided with a discharge port. The electric push rod drives the side of the storage box away from the main body of the reactor to move upward, so that the side of the storage box close to the main body of the reactor tilts downward.

[0007] Furthermore, both the feed trough and the discharge port are connected to the inner cavity of the storage box.

[0008] Furthermore, the inner wall of the discharge port is provided with a baffle assembly, the baffle assembly including an outer shaft body rotatably connected to the inner wall of the discharge port, and an inner shaft body fixedly connected to the inner wall of the discharge port.

[0009] Furthermore, a reset torsion spring is sleeved on the outer wall of the inner shaft body. One end of the reset torsion spring is fixedly connected to an external rod, and the end of the external rod away from the reset torsion spring is fixedly connected to a partition body. The external rod is fixedly connected to the outer shaft body, and the size of the partition body matches that of the discharge port.

[0010] Furthermore, in the relaxed state of the reset torsion spring, the partition body completely seals the discharge port.

[0011] Furthermore, under the pressed state of the reset torsion spring, the partition body moves out of the discharge port.

[0012] Compared with the prior art, the beneficial effects of this utility model include: according to the production formula, different types of raw materials are fed into multiple sets of feeding components distributed around the outer wall of the reactor body. The multiple sets of feeding components can ensure that multiple raw materials can be fed at the same time. The electric push rod drives the electric push rod to convert electrical energy into mechanical energy. According to the preset program, its output end makes a linear extension and retraction movement. When the electric push rod extends, it drives one end of the storage box connected to it to rise, so that the storage box is tilted. As the storage box tilts, the raw materials inside flow to the discharge port under the action of gravity, ready to enter the reactor, thus achieving the purpose of synchronous feeding. This greatly shortens the feeding time, improves production efficiency, and solves the problem that the existing device can often only feed sequentially, which not only greatly extends the production cycle, but also easily leads to poor product quality due to the difference in mixing time of the raw materials entering the reactor sequentially.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] Please see Figures 1-4 To address the issue that existing equipment often requires sequential feeding, which significantly lengthens the production cycle and leads to poor product quality due to differences in mixing time between raw materials entering the reactor sequentially, the following preferred technical solutions are provided:

[0021] A corrosion-resistant EPS reactor feeding device includes a feeding assembly 2 disposed on the upper end of the reactor body 1. Multiple sets of feeding assemblies 2 are evenly distributed around the outer wall of the reactor body 1. Different feeding assemblies 2 can feed different types of raw materials, such as one set for polystyrene particles, one set for foaming agent, and another set for flame retardant. Each feeding assembly 2 includes an outer frame 21 fixedly connected to the outer wall of the reactor body 1. An electric actuator 22 is installed inside the cavity of the outer frame 21. The output end of the electric actuator 22 is shaft-connected to a storage tank 23, one end of which rests on the reactor body. The upper wall of the reactor body 1 has a feed trough 24 on its upper wall. The inner wall of the feed trough 23 is fixedly connected to the storage tank 23, and the outer wall of the storage tank 23 has a discharge port. The feed trough 24 and the discharge port are both connected to the inner cavity of the storage tank 23. The electric push rod 22 drives the side of the storage tank 23 away from the reactor body 1 to move upward, so that the side of the storage tank 23 close to the reactor body 1 tilts downward. When the storage tank 23 tilts, the internal raw materials flow to the discharge port under the action of gravity, ready to enter the reactor.

[0022] A baffle assembly 26 is provided on the inner wall of the discharge port. The baffle assembly 26 includes an outer shaft body 261 rotatably connected to the inner wall of the discharge port and an inner shaft body 262 fixedly connected to the inner wall of the discharge port. A return torsion spring 263 is sleeved on the outer wall of the inner shaft body 262. An external rod 264 is fixedly connected to one end of the return torsion spring 263. A baffle body 265 is fixedly connected to the end of the external rod 264 away from the return torsion spring 263. The external rod 264 is fixedly connected to the outer shaft body 261. The size of the baffle body 265 matches that of the discharge port. When the return torsion spring 263 is relaxed, the baffle body 265 completely seals the discharge port. In the compressed state, the partition body 265 moves out of the discharge port. In the relaxed state of the reset torsion spring 263, its elastic potential energy makes the partition body 265 tightly fit the discharge port, completely sealing the discharge port and preventing the material from accidentally falling out of the discharge port when the storage box 23 is not tilted. When the electric push rod 22 drives the storage box 23 to tilt, the gravitational force generated by the material in the storage box 23 acts on the partition body 265, overcoming the elastic force of the reset torsion spring 263, causing the partition body 265 to rotate around the outer shaft body 261. The reset torsion spring 263 enters the compressed state, the partition body 265 moves out of the discharge port, and the material can flow out from the discharge port into the reactor.

[0023] Specifically, when the corrosion-resistant EPS reactor feeding device is started, different types of raw materials are first fed into multiple sets of feeding components 2 distributed around the outer wall of the reactor body 1 according to the production formula. The multiple sets of feeding components 2 can ensure that multiple raw materials can be fed at the same time, driving the electric push rod 22. The electric push rod 22 converts electrical energy into mechanical energy. According to the preset program, its output end makes a linear extension and retraction movement. When the electric push rod 22 extends, it drives one end of the storage box 23 connected to it to rise, so that the storage box 23 is tilted. As the storage box 23 tilts, the raw materials inside flow to the discharge port under the action of gravity, ready to enter the reactor, realizing the purpose of synchronous feeding, which greatly shortens the feeding time, improves production efficiency, and solves the problem that the existing device can only feed sequentially, which not only greatly extends the production cycle, but also the raw materials entering the reactor sequentially are prone to poor product quality due to the difference in mixing time.

[0024] Because a baffle assembly 26 is installed at the discharge port, and when the reset torsion spring 263 is in a relaxed state, the baffle body 265 tightly adheres to the discharge port under the action of its elastic potential energy, which can prevent the material from accidentally falling out when the storage box 23 is in a horizontal state. When the storage box 23 is tilted, the gravitational force generated by the material overcomes the elastic force of the reset torsion spring 263, pushing the baffle body 265 to rotate around the outer shaft body 261, so that the reset torsion spring 263 enters the clamping state, the baffle body 265 moves out of the discharge port, and the material flows smoothly out of the discharge port into the reactor. When the material is discharged, the electric push rod 22 retracts, and the storage box 23 returns to a horizontal state. At this time, the elastic force of the reset torsion spring 263 causes the partition body 265 to rotate in the opposite direction, re-sealing the discharge port tightly. The partition body 265, in conjunction with the strong reset of the reset torsion spring 263, ensures that there is no material residue after feeding, ensuring precise control of the feeding amount each time, and providing a guarantee for stable product quality. The entire feeding process, through the coordinated operation of various components, efficiently, accurately and stably completes the delivery of various raw materials to the reactor.
