Description

Technical Field

[0001] This utility model relates to the field of PVC granule manufacturing technology, and in particular to a medical PVC granule collection device. Background Technology

[0002] PVC is a polymer formed by the polymerization of vinyl chloride monomers under the initiation of peroxides or other initiators, or under the action of light and heat, according to the free radical polymerization mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. It is a non-crystalline material, and in practical applications, stabilizers, lubricants, processing aids, colorants, impact modifiers, and other additives are often added. It possesses non-flammability, high strength, resistance to climate change, and excellent geometric stability. During the production of PVC granules, after cutting the granules, they need to be collected and bottled promptly.

[0003] Currently available material collection devices generate a certain amount of dust during the collection process due to the collision of particles. Long-term inhalation of this dust can cause great harm to human health. The colliding particles are also prone to splashing, resulting in waste. Utility Model Content

[0004] To address the aforementioned technical problems, a medical PVC granule collection device is provided.

[0005] To achieve the above objectives, this utility model discloses a medical PVC granule collection device, including a collection box. The top of the collection box is provided with a feed pipe connected to the tail of a granulator. A damping structure plate is installed inside the collection box below the feed pipe. A discharge cylinder is provided at the bottom of the damping structure plate. At least two opposing bent side plates are provided inside the discharge cylinder. The side plates have mesh holes that penetrate the side plates and the discharge cylinder. A filter screen is installed on the outside of the discharge cylinder at the position corresponding to the mesh holes. An exhaust fan is installed on the discharge cylinder outside the filter screen.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] One embodiment of this utility model is as follows: Figure 1As shown, the top of the collection box 1 is equipped with a feed pipe 2 connected to the tail of the granulator. A damping structure plate 3 is installed inside the collection box 1 below the feed pipe 2. A discharge cylinder 4 is installed at the bottom of the damping structure plate 3. At least two opposing bent side plates 5 are installed inside the discharge cylinder 4. Mesh holes are opened on the side plates 5, penetrating the side plates 5 and the discharge cylinder 4. A filter screen 6 is installed on the outside of the discharge cylinder 4 at the corresponding positions of the mesh holes. A blower 7 is installed on the discharge cylinder 4 outside the filter screen 6. A discharge port is located at the bottom of the discharge cylinder 4, and a [missing information - likely a device or equipment] is installed at the discharge port. The electrostatic precipitator 8 has a bagging mechanism at its bottom to bag the cleaned granules. A water mist generator 9 is installed between the discharge cylinder 4 and the collection box 1. The granules are guided by the side plates inside the discharge cylinder and fall orderly onto the guide plate to move to the discharge port to complete the bagging. The dust generated after the granules collide on the bending section of the side plate is passed through the mesh by the exhaust fan and adheres to the surface of the filter screen. Together with the electrostatic precipitator at the discharge port, the dust generated during the granule collection process is treated, reducing the harm to the health of the operators.

[0020] The damping structure plate 3 is an arc-shaped plate with its concave surface facing the feeding direction of the feed pipe 2. The damping structure plate 3 includes a base plate and damping material disposed on the concave surface of the base plate. The base plate is a vibratory structure that can reduce the rebound force when the granules fall from above onto the surface of the damping structure plate, preventing the granules from splashing everywhere. At the same time, the arc-shaped structure has a larger surface area than the planar structure, which can withstand more granules and guide the granules to the top of the feed cylinder.

[0021] like Figure 2 As shown, the side plate 5 includes a fixed section 51 fixed to the inner wall of the discharge cylinder 4 and a bent section 52 located below the fixed section 51. The mesh is set on the fixed section 51. The two side plates 5 are installed in a staggered manner so that the bent section of one side plate points to the center of the bent section of the other side plate. Specifically, in this embodiment, the angle between the fixed section and the bent section is 135°, which provides a buffer during the descent of the granules and provides collision space for the granules, so that the dust attached to the surface of the granules is raised and easy to clean.

[0022] The bottom of the discharge cylinder 4 is a conical structure. The inner wall of the conical structure is provided with a guide plate 41 that spirals downward to the discharge port. The bent section of the bottom side plate faces the top of the guide plate 41. The guide plate structure transports the granules in an orderly manner, avoiding large amounts of granules being concentrated in the bag and causing splashing and waste.

[0023] The mesh openings on the feed cylinder 4 correspond to the mesh openings on the side plate 5. The mesh diameter is smaller than the diameter of the particles, allowing only dust to pass through and preventing particles from clogging the mesh. Figure 3 As shown, the filter screen 6 is attached to the outer wall of the feed cylinder 4 by magnetic strips, which makes it easy to install and remove and facilitates cleaning and replacement later.

[0024] The exhaust fan 7 is installed in a position corresponding to the filter screen 6, ensuring that the dust inside the discharge cylinder can be smoothly adsorbed from the mesh onto the filter screen.

[0025] A middle partition is provided between the damping structure plate 3 and the discharge cylinder 4. A through hole is opened in the center of the middle partition and communicates with the discharge cylinder 4. An agitator impeller 10 is installed in the collection box 1 above the through hole. The granules at the top of the collection box are agitated from time to time to prevent clogging of the through hole of the middle partition. A water mist generator 9 is installed below the middle partition around the discharge cylinder 4. The water mist generator periodically generates water mist in the collection box to adsorb and clean the dust inside. The exhaust fan, water mist generator and electrostatic precipitator are all relatively mature existing technologies. The specific structure will not be described in detail in this application.

[0026] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections.
