Description

Technical Field

[0001] This utility model relates to the field of ventilation device technology, and in particular to a novel ventilation device for production lines. Background Technology

[0002] Currently, when processing products, it is generally necessary to set up a dedicated production line for specialized processing and production. This allows for large-scale, modular production of products, which can reduce production costs. However, ventilation devices are required during production.

[0003] Existing ventilation systems typically involve creating vents in the factory walls, installing fans or air pumps inside these vents, and then connecting ventilation ducts to the vents to direct airflow onto the production line. However, because the ventilation ducts are usually installed on the factory ceiling, the distance between the exhaust vents and the production line is significant and cannot be adjusted, resulting in poor ventilation. Furthermore, since the fans are typically fixed to the vents with multiple bolts, maintenance requires dismantling the ventilation ducts and then removing the fan from the vents, which is cumbersome and inefficient. Therefore, we propose a novel ventilation system for production lines. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a novel ventilation device for production lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel ventilation device for a production line is designed, including a ventilation duct, which is installed at the top of the interior of the factory building by a bracket, and one end of the ventilation duct extends to the outside of the factory building;

[0006] The bottom of the ventilation duct is equipped with several first connecting pipes, and the bottom of each first connecting pipe is equipped with a second connecting pipe. An installation sleeve is provided between the first connecting pipe and the second connecting pipe. Pipe joints are installed at both ends of each installation sleeve. The first connecting pipe and the second connecting pipe are provided with receiving grooves at the ends of the pipe joints. One end of each pipe joint extends into the corresponding receiving groove. A fan is installed inside the installation sleeve.

[0007] A pair of limiting rings are installed at the end of the first connecting pipe and the second connecting pipe near the mounting sleeve. Each pair of limiting rings forms an annular groove. An arc-shaped pipe clamp is provided in the annular groove. Opening grooves are provided at the end of the first connecting pipe and the second connecting pipe near the mounting sleeve and on the side of the limiting ring.

[0008] Each arc-shaped pipe clamp has a connecting block installed at both ends. One of the connecting blocks has a mounting hole on its side, and a tightening bolt is installed inside the mounting hole. The other connecting block has a second threaded through hole coaxially on its side. One end of each tightening bolt is screwed into the corresponding second threaded through hole and threadedly connected to the second threaded through hole.

[0009] The bottom of the second connecting pipe is coaxially provided with a vent pipe. The bottom of the vent pipe extends to the outside of the second connecting pipe. The bottom of each vent pipe is connected to an adjustment pipe through a connecting flange. The end of each adjustment pipe is equipped with a ventilation hood, which is located above the production line.

[0010] The bottom side of the second connecting pipe is equipped with a connecting ring. Each connecting ring has at least one groove on its side. Each groove has an adjusting bolt inside, with one end of the adjusting bolt extending to the outside of the groove. A first threaded through hole is opened at one end of the groove. The other end of the adjusting bolt is screwed into the first threaded through hole and threadedly connected to the first threaded through hole. When the adjusting bolt is tightened, one end of the adjusting bolt passes through the first threaded through hole and presses tightly against the side of the vent pipe.

[0011] Preferably, the inner walls of the first connecting pipe and the second connecting pipe form a stepped structure with the inner wall of the corresponding receiving groove, and when the pipe joint extends into the receiving groove, the end of the pipe joint abuts against the corresponding stepped surface.

[0012] Preferably, the arc-shaped pipe clamp is made of a flexible metal material.

[0013] Preferably, the regulating tube is made of a metal-shaped flexible tube.

[0014] Preferably, a second anti-detachment ring is installed at the bottom of the inner part of the second connecting pipe, and a first anti-detachment ring is installed on the top side of the vent pipe. When the vent pipe is moved to the lowest end, the bottom of the first anti-detachment ring abuts against the top of the second anti-detachment ring.

[0015] Preferably, both the end of the pipe joint and the inner end face of the receiving groove are provided with sealing gaskets.

[0016] Preferably, the side of the first anti-detachment ring is sealed to the inner wall of the second connecting pipe.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] 1. The pipe joint can be fixed in the receiving groove by tightening the bolts, and then the fan can be connected with the first connecting pipe and the second connecting pipe. It is easy to install and easy to disassemble and maintain.

[0019] 2. The position between the vent pipe and the second connecting pipe can be adjusted by loosening the adjusting screw, and the position of the ventilation hood can be adjusted as needed by bending the adjusting pipe to improve the ventilation effect. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A novel ventilation device for a production line includes a ventilation duct 1, which is installed at the top of the interior of the factory building via a bracket, with one end of the ventilation duct 1 extending to the outside of the factory building, so that the ventilation duct 1 can be connected to the external environment.

[0028] like Figure 2 and Figure 3As shown, several first connecting pipes 2 are installed at the bottom of the ventilation duct 1. Each first connecting pipe 2 has a second connecting pipe 5 at its bottom. An installation sleeve 3 is provided between the first connecting pipe 2 and the second connecting pipe 5. Pipe joints 4 are installed at both ends of each installation sleeve 3. The first connecting pipe 2 and the second connecting pipe 5 have a receiving groove 17 inside the end near the pipe joint 4. One end of each pipe joint 4 extends into the corresponding receiving groove 17. A fan 18 is installed inside the installation sleeve 3. In actual use, the fan 18 can transport outside air through the ventilation duct 1 and the first connecting pipe 2 to the second connecting pipe 5.

[0029] It should be noted that, as Figure 3 As shown, the inner walls of the first connecting pipe 2 and the second connecting pipe 5 form a stepped structure with the inner wall of the corresponding receiving groove 17. When the pipe joint 4 extends into the receiving groove 17, the end of the pipe joint 4 abuts against the corresponding stepped surface. Both the end of the pipe joint 4 and the inner end face of the receiving groove 17 are provided with sealing gaskets. In actual use, the connection between the pipe joint 4 and the first connecting pipe 2 and the second connecting pipe 5 can be sealed by the cooperation between the pipe joint 4 and the receiving groove 17, so as to prevent air leakage during ventilation.

[0030] like Figure 2 and Figure 3 As shown, a pair of limiting rings 16 are installed at the end of the first connecting pipe 2 and the second connecting pipe 5 near the mounting sleeve 3. Each pair of limiting rings 16 forms an annular groove. An arc-shaped pipe clamp 6 is provided in the annular groove. Opening grooves 24 are provided at the end of the first connecting pipe 2 and the second connecting pipe 5 near the mounting sleeve 3 and on the side of the limiting ring 16. In actual use, the first connecting pipe 2 and the second connecting pipe 5 can be fixed together with the pipe joint 4 by the arc-shaped pipe clamp 6. In this way, the fan 18 can be fixed between the first connecting pipe 2 and the second connecting pipe 5.

[0031] like Figure 2 and Figure 5 As shown, each arc-shaped pipe clamp 6 has a connecting block 14 installed at both ends. One of the connecting blocks 14 has a mounting hole 23 on its side, and a tightening bolt 15 is installed inside the mounting hole 23. The other connecting block 14 has a second threaded through hole 22 coaxially opened on its side. One end of each tightening bolt 15 is screwed into the corresponding second threaded through hole 22 and threadedly connected to the second threaded through hole 22. The arc-shaped pipe clamp 6 can be made of elastic metal material or other elastic high-strength plastic. In actual use, by tightening the tightening bolt 15, the two ends of the arc-shaped pipe clamp 6 are contracted, so that the arc-shaped pipe clamp 6 squeezes the ends of the first connecting pipe 2 and the second connecting pipe 5, clamping and fixing the pipe joint 4, which is convenient for fixing.

[0032] like Figure 1 and Figure 4 As shown, a vent pipe 8 is coaxially provided at the bottom of the inner part of the second connecting pipe 5. The bottom end of the vent pipe 8 extends to the outside of the second connecting pipe 5, and the bottom end of each vent pipe 8 is connected to an adjusting pipe 10 through a connecting flange 9. A ventilation hood 11 is installed at the end of each adjusting pipe 10. The ventilation hood 11 is located above the production line. In actual use, the vent pipe 8 can be moved along the second connecting pipe 5, so that the height of the ventilation hood 11 can be adjusted and the use effect can be improved.

[0033] It should be noted that the regulating pipe 10 is made of a metal shaped flexible tube, so that the regulating pipe 10 can be bent to any angle, which can adjust the tilt angle and position of the ventilation hood 11 as needed, thereby improving the ventilation effect.

[0034] like Figure 2 and Figure 3 As shown, a connecting ring 7 is installed on the bottom side of the second connecting pipe 5. Each connecting ring 7 has at least one groove 13 on its side. Each groove 13 has an adjusting bolt 12 inside, and one end of the adjusting bolt 12 extends to the outside of the groove 13. A first threaded through hole 21 is opened at one end of the groove 13. The other end of the adjusting bolt 12 is screwed into the first threaded through hole 21 and threadedly connected to the first threaded through hole 21. When the adjusting bolt 12 is tightened, one end of the adjusting bolt 12 passes through the first threaded through hole 21 and presses tightly against the side of the vent pipe 8. In actual use, after adjusting the position between the vent pipe 8 and the second connecting pipe 5, the operator tightens the adjusting bolt 12 so that one end of the adjusting bolt 12 presses tightly against the side of the vent pipe 8, thus fixing the vent pipe 8 and the second connecting pipe 5 together. The fixing is convenient.

[0035] Specifically, in use, the operator can loosen the adjusting bolt 12 so that one end of the adjusting bolt 12 is detached from the side wall of the vent pipe 8. Then, the operator moves the vent pipe 8 along the second connecting pipe 5 and adjusts the vent pipe 8 to the preset position. After that, the operator tightens the adjusting bolt 12 to fix the vent pipe 8 and the second connecting pipe 5 together. Then, the operator bends the adjusting pipe 10 to the preset angle, and the ventilation hood 11 can be adjusted to the preset position as needed to improve the ventilation effect. When the fan 18 needs to be repaired, the operator only needs to loosen the tightening bolt 15 to loosen the arc-shaped pipe clamp 6. Then, the operator removes the pipe joint 4 from the receiving groove 17 to complete the disassembly of the fan 18, which is convenient for maintenance.

[0036] Furthermore, such as Figure 4As shown, a second anti-detachment ring 20 is installed at the bottom of the inner part of the second connecting pipe 5, and a first anti-detachment ring 19 is installed on the top side of the vent pipe 8. When the vent pipe 8 moves to the lowest end, the bottom of the first anti-detachment ring 19 abuts against the top of the second anti-detachment ring 20. In actual use, the vent pipe 8 can be limited by the cooperation of the first anti-detachment ring 19 and the second anti-detachment ring 20, so that the vent pipe 8 will not come out of the second connecting pipe 5.

[0037] Furthermore, the side of the first anti-detachment ring 19 is sealed to the inner wall of the second connecting pipe 5, so that during ventilation, the air blown out by the fan 18 will not leak from the gap between the first anti-detachment ring 19 and the second connecting pipe 5.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
