Description

Technical Field

[0001] This utility model belongs to the field of plastic pipe manufacturing technology, and in particular relates to an anti-material accumulation device for the raw material transportation process of PE-Xa pipes. Background Technology

[0002] Peroxide cross-linked polyethylene (PE-Xa) pipes are a high-quality product widely used in underfloor heating. After cross-linking, the physical, mechanical, and chemical properties, heat resistance, and pressure resistance of the pipes are significantly improved. In long-term thermal stability tests, under any temperature conditions (up to 110℃), the hydrostatic predictive strength curve shows no inflection point and no brittle fracture before 8760 hours, demonstrating excellent anti-aging and pressure resistance, which greatly increases the safety and reliability of the system operation.

[0003] Currently, because PE-Xa raw materials use different forms of raw materials such as high-density polyethylene, peroxides, and antioxidants, material accumulation is very likely to occur during the raw material transportation process, leading to material shortages at the discharge port, conveying port, and other locations, causing production interruptions, seriously affecting the normal production order, and greatly increasing production costs. Utility Model Content

[0004] In view of this, the present invention aims to propose an anti-material accumulation device for the raw material transportation process of PE-Xa pipes, in order to solve the problem that, due to the different forms of raw materials such as high-density polyethylene, peroxide, and antioxidants used in PE-Xa raw materials, material accumulation is very likely to occur during the raw material transportation process, which leads to material breakage at the discharge port, conveying port, and other positions, causing production interruption, seriously affecting the normal production order, and greatly increasing production costs.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides an anti-accumulation device for the raw material transportation process of PE-Xa pipes, comprising an upper hopper of an extruder, a vibrating motor, and a level gauge. The upper hopper of the extruder includes an upper connecting hopper and a lower integrated hopper. The lower integrated hopper is connected to the upper connecting hopper by bolts. The top of the upper connecting hopper is connected to the PE-Xa pipe raw material transportation pipeline. A screen is provided inside the upper connecting hopper, and a pressure sensor is fixed on the screen. The discharge port of the lower integrated hopper is connected to the extruder. The level gauge is connected to the upper hopper of the extruder. The lower integrated hopper is connected to the vibrating motor, and the encoder of the vibrating motor is connected to the level gauge and the pressure sensor.

[0007] Furthermore, the lower-part hopper comprises, from top to bottom, a first connecting hopper, a second connecting hopper, and a third connecting hopper. The first connecting hopper is cylindrical with an inclined plate at the bottom. The upper part of the first connecting hopper is fixed to the upper connecting hopper by a first connecting bolt. The first connecting hopper and the second connecting hopper are fixed by a second connecting bolt. A first stud connecting plate is connected at the bolt connection point between the bottom of the first connecting hopper and the second connecting hopper. The side wall of the second connecting hopper is convexly arc-shaped. The second connecting hopper and the third connecting hopper are fixed by a third connecting bolt. A second stud connecting plate is connected at the bolt connection point between the second connecting hopper and the third connecting hopper. The third connecting hopper is funnel-shaped, with a screen support frame connected to its inner wall. A screen is connected to the upper part of the screen support frame. The screen is inverted funnel-shaped. The first connecting hopper and the third connecting hopper are connected by connecting screws and locked with fixing bolts.

[0008] Furthermore, the first connecting hopper is connected to the first connecting plate in the bent connecting plate on its side. The first connecting plate is symmetrically arranged with respect to the center line of the rectangle protruding from the first stud connecting plate, and the bottom of the first connecting hopper is connected to the first stud connecting plate. The third connecting hopper is connected to the second connecting plate in the bent connecting plate on its side. The first connecting plate is symmetrically arranged with respect to the center line of the rectangle protruding from the second stud connecting plate. The connection surface between the second connecting plate and the third connecting hopper is an inclined slope, and the top of the second connecting plate is connected to the second stud connecting plate.

[0009] Furthermore, the vibrating motor is connected to the third connecting hopper via a motor mounting base. The motor mounting base includes a first inclined connecting plate, an arc connecting plate, a vertical mounting plate, and a second inclined connecting plate. The vertical mounting plate is connected to the vibrating motor. The first inclined connecting plate and the arc connecting plate are used to fix the outer surface of the vibrating motor and the third connecting hopper.

[0010] Furthermore, the connection between the top of the upper connecting hopper and the PE-Xa pipe material conveying pipeline is a rounded corner pipe.

[0011] Compared with existing technologies, the anti-accumulation device for the raw material transportation process of PE-Xa pipes described in this utility model has the following advantages:

[0012] (1) The vibratory motor of this utility model is connected to the level gauge and screen pressure sensor through an encoder, which can monitor the level, screen pressure and working status of the vibratory motor in real time, so as to realize more efficient automated control at the feed point of the extruder and reduce manual intervention. According to the changes in the level and screen pressure, the frequency and amplitude of the vibratory motor are dynamically adjusted to ensure uniform distribution and efficient screening of materials. Through real-time monitoring, potential faults such as excessively high level or screen blockage can be detected in advance, and timely measures can be taken to avoid production interruption.

[0013] (2) The rounded corner pipe design of this utility model can significantly reduce the bends in the pipe, thereby reducing the resistance of the raw material during the transportation process. In actual use, eddies and pressure loss are easily formed at the bends, while the rounded corner design can smoothly transition and reduce these adverse effects. At the same time, the rounded corner design helps the PE-Xa pipe material to be evenly distributed in the pipe, reducing local accumulation and improving the transportation efficiency of the PE-Xa pipe material.

The side wall of the second connecting hopper 402 is convex arc-shaped. The second connecting hopper 402 and the third connecting hopper 403 are fixed by the third connecting bolt 17. The bolt connection between the second connecting hopper 402 and the third connecting hopper 403 is connected to the second stud connecting plate 20. The third connecting hopper 403 is funnel-shaped, and its inner wall is connected to the screen support frame 9. The upper part of the screen support frame 9 is connected to the screen 11, which is inverted funnel-shaped. The first connecting hopper 401 and the third connecting hopper 403 are connected by the connecting screw 6 and locked with the fixing bolt 7.

[0030] Specifically, in this embodiment, the side of the first connecting hopper 401 is connected to the first connecting plate 501 in the bent connecting plate 5. The first connecting plate 501 is symmetrically arranged with respect to the center line of the rectangle protruding from the first stud connecting plate 19, and the bottom of the first connecting hopper 401 is connected to the first stud connecting plate 19. The side of the third connecting hopper 403 is connected to the second connecting plate 502 in the bent connecting plate 5.

The connecting surface between the second connecting plate 502 and the third connecting hopper 403 is an inclined surface, and the top of the second connecting plate 502 is connected to the second stud connecting plate 20.

[0031] Specifically, in this embodiment, the vibrating motor 3 and the third connecting hopper 403 are connected by a motor mounting base 12. The motor mounting base 12 includes a first inclined connecting plate 13, an arc connecting plate 14, a vertical fixing plate 15, and a second inclined connecting plate 16. The vertical fixing plate 15 is connected to the vibrating motor 3. The first inclined connecting plate 13 and the arc connecting plate 14 are used to fix the outer surfaces of the vibrating motor 3 and the third connecting hopper 403. The first inclined connecting plate 13 is symmetrically arranged with respect to the centerline of the vertical fixing plate 15.

The inclined surfaces of the first inclined connecting plate 13, the second inclined connecting plate 16, and the arc connecting plate 14 are fixed to the outer wall of the third connecting hopper 403.

[0032] Specifically, in this embodiment, the connection between the top of the upper connecting hopper 2 and the PE-Xa pipe material conveying pipeline 1 is a rounded corner pipe.

[0033] In this embodiment, the rounded corner pipe design significantly reduces the number of bends within the pipe, thereby reducing resistance during material transport. In actual use, bends easily lead to eddies and pressure losses, while the rounded corner design provides a smooth transition, reducing these adverse effects. Simultaneously, the rounded corner design helps ensure uniform distribution of PE-Xa pipe material within the pipe, reducing localized accumulation and improving the transport efficiency of PE-Xa pipe material. The vibrating hopper effectively prevents material accumulation inside, which can cause uneven discharge. The vibration caused by the vibrating motor rotating the eccentric wheel vibrates the hopper. The special internal design of the hopper also ensures smooth material discharge. The vibrating motor is fixed to the hopper shell to prevent material accumulation and blockage. This method, by vibrating the hopper shell, causes minute vibrations within the hopper, preventing material from adhering to the hopper wall or forming bridging. The modular, modular hopper improves the flexibility and ease of maintenance, especially in situations requiring frequent hopper replacement or cleaning. In the screening and conveying process of PE-Xa raw materials, the split-type combined hopper can better adapt to different production needs, ensuring the uniformity and quality of the raw materials. During the processing of PE-Xa raw materials, the screening process should generally be carried out before the extruder. This ensures that the raw materials entering the extruder meet the requirements and avoids excessively large particles from adversely affecting the extruder and the quality of the final product. Therefore, the screen is located in the hopper above the extruder.

[0034] The vibratory motor is connected to the level gauge and screen pressure sensor via an encoder, enabling real-time monitoring of the material level, screen pressure, and the motor's operating status. This allows for more efficient automated control at the extruder feed point, reducing manual intervention. Based on changes in material level and screen pressure, the frequency and amplitude of the vibratory motor are dynamically adjusted to ensure uniform material distribution and efficient screening. Real-time monitoring allows for early detection of potential faults, such as excessively high material levels or screen blockage, enabling timely intervention to prevent production interruptions.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
