Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and more specifically to an energy-saving blowing tool. Background Technology

[0002] In the daily production process of a tobacco processing workshop, equipment maintenance is a crucial step in ensuring production efficiency and product quality. After each day's production activities, compressed air is used to clean the equipment, removing tobacco dust, fine tobacco residue, and other contaminants that have accumulated on and around the equipment during production. Previously, a simple cleaning tool was commonly used, consisting of an 800mm 4-point stainless steel tube as the cleaning rod, with a 6mm hole at the top for releasing compressed air. While this tool achieved the cleaning purpose to some extent, it had significant drawbacks.

[0003] First, the traditional cleaning tool has a limited coverage area. This means that in order to achieve the requirement of thoroughly cleaning the equipment, the operator often needs to frequently move the position of the cleaning rod and repeatedly clean multiple local areas. This undoubtedly increases the complexity of the operation and the time cost.

[0004] Secondly, and more critically, the excessive consumption of compressed air is a major issue. In today's industrial production sector, companies are advocating energy conservation and emission reduction, striving to optimize resource utilization efficiency, reduce energy costs, and simultaneously reduce carbon emissions to fulfill their social responsibility. However, existing cleaning tools, due to design limitations, suffer from low compressed air utilization efficiency, consuming a large amount of this valuable energy resource during cleaning operations. This contradicts the overall strategic direction of energy conservation and emission reduction for enterprises, and urgently requires improvement and optimization through technological innovation to achieve the dual goals of meeting the process requirements of on-site equipment cleaning while effectively reducing compressed air consumption, thereby improving the economic and environmental benefits of enterprise production and operation.

[0005] In view of this, the present invention provides an energy-saving purging tool, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An energy-saving purging tool, comprising:

[0008] A long pipe, one end of which forms a variable-diameter outlet section with a reduced opening diameter;

[0009] The air supply pipe is sleeved outside the variable diameter air outlet section and fixedly connected to the long pipe. The air supply pipe has multiple air supply ports circumferentially.

[0010] An air nozzle is connected to the end of the air supply pipe away from the long pipe, and there is a gap between the inlet of the air nozzle and the end of the variable diameter outlet section away from the long pipe.

[0011] Through the above technical solution, this utility model uses a combination design of a long pipe, a variable diameter air outlet section, an air supply pipe and an air nozzle to attract outside air by utilizing the Venturi effect, thereby achieving the dual effect of increasing the purging area and reducing compressed air consumption, improving purging efficiency while reducing energy consumption.

[0012] Preferably, in the above-mentioned energy-saving purging tool, the variable-diameter air outlet section includes a tapered tube and a throat tube that are sequentially and fixedly connected to the end of the long tube; the large-diameter end of the tapered tube is fixedly connected to the long tube, and the small-diameter end of the tapered tube is fixedly connected to the throat tube.

The design of the first external thread of the long tube facilitates the connection of the ball valve and the pressure control hose, improves the flexibility and control capability of the tool, and makes it convenient to adjust the on / off state of compressed air as needed.

[0015] Preferably, in the above-mentioned energy-saving purging tool, the outer diameter of the air supply pipe is the same as the outer diameter of the long pipe.

[0016] Preferably, in the above-mentioned energy-saving purging tool, the outer wall of the long tube has a second external thread, and an adjusting tube is sleeved on the outer side of the long tube. One end of the adjusting tube is threadedly connected to the second external thread, and the other end of the adjusting tube corresponds to the air inlet. The combined design of the adjusting tube and the air inlet allows for flexible control of the purging intensity by adjusting the air supply, while improving the applicability and operability of the tool, enabling it to adapt to different cleaning needs and scenarios.

[0017] Preferably, in the above-mentioned energy-saving purging tool, a rubber ring is fixed along one end of the regulating tube corresponding to the air inlet, and the rubber ring is in contact with the outer wall of the air inlet tube.

[0018] Preferably, in the above-mentioned energy-saving purging tool, the outer wall of the adjusting tube has rotational friction texture.

[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an energy-saving purging tool, which has the following beneficial effects:

[0020] 1. Energy saving and environmental protection: The Venturi effect reduces compressed air consumption, which meets the industrial energy saving and consumption reduction goals and reduces energy waste.

[0021] 2. High-efficiency cleaning: The combination of flat nozzle and conical throat design expands the blowing area, provides stable airflow, and improves cleaning efficiency.

[0022] 3. Flexible operation: The adjustable tube and long tube thread design enhance the tool's adaptability, allowing for flexible adjustment of the blowing intensity according to cleaning needs.

[0023] 4. Economy and equipment lifespan: Reduce energy consumption and wear and tear on equipment parts, extend tool lifespan, and reduce equipment maintenance costs. Attached Figure Description

[0039] 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.

[0040] Example 1:

[0041] See appendix Figure 1 To be continued Figure 3 This utility model discloses an energy-saving purging tool, comprising:

[0042] Long pipe 1, one end of long pipe 1 forms a variable diameter air outlet section 11 with a reduced diameter;

[0043] Air supply pipe 2 is sleeved on the outside of the variable diameter air outlet section 11 and fixedly connected to the long pipe 1. The air supply pipe 2 has multiple air supply ports 21 circumferentially.

[0044] Air nozzle 3 is connected to the end of the air supply pipe 2 away from the long pipe 1. There is a gap between the inlet of air nozzle 3 and the end of the variable diameter outlet section 11 away from the long pipe 1.

[0045] To further optimize the above technical solution, the variable diameter air outlet section 11 includes a tapered pipe 111 and a throat pipe 112 that are fixedly connected to the end of the long pipe 1 in sequence; the large diameter end of the tapered pipe 111 is fixedly connected to the long pipe 1, and the small diameter end of the tapered pipe 111 is fixedly connected to the throat pipe 112.

[0046] To further optimize the above technical solution, the air nozzle 3 is a flat nozzle.

[0047] To further optimize the above technical solution, the end of the long pipe 1 away from the variable diameter air outlet section 11 has a first external thread 12. The first external thread 12 is used to connect the ball valve and the pressure control hose. The ball valve can control the on and off of compressed air.

[0048] To further optimize the above technical solution, the outer diameter of the air supply pipe 2 is the same as the outer diameter of the long pipe 1.

[0049] In this embodiment, the air inlet 21 is a round hole.

[0050] To reduce compressed air consumption while meeting on-site cleaning requirements, the purging tool of this embodiment was designed and manufactured. The purging tool of this embodiment utilizes the Venturi tube principle. Compressed air enters the throat 112 through the long tube 1 and the tapered tube 111. As the throat 112 becomes narrower, the compressed air flow changes from coarse to fine, the pressure of the compressed air decreases, and the flow velocity increases, forming a "vacuum" zone around the outlet of the throat 112. This causes a large amount of surrounding air to be drawn in through the air inlet 21 of the air supply pipe 2 and ejected along with the compressed air through the air nozzle 3 to purge the equipment.

[0051] This embodiment can reduce the consumption of compressed air, saving energy and reducing consumption; by using a flat nozzle, the purging area is increased, which can improve the purging effect and efficiency; by increasing the purging area and appropriately reducing the nozzle outlet speed, dust can be reduced.

[0052] Example 2:

[0053] See appendix Figure 4 To be continued Figure 6 This utility model embodiment is a further improvement on embodiment 1, aiming to improve the adjustability of purging: the outer wall of the long tube 1 has a second external thread 13, and an adjustment tube 4 is sleeved on the outer side of the long tube 1. One end of the adjustment tube 4 is threadedly connected to the second external thread 13, and the other end of the adjustment tube 4 corresponds to the air supply port 21.

[0054] To further optimize the above technical solution, a rubber ring 41 is fixed to one end of the regulating pipe 4 corresponding to the air supply port 21, and the rubber ring 41 is in contact with the outer wall of the air supply pipe 2. The friction of the rubber ring 41 can ensure the stability of the regulating pipe 4 during use.

[0055] To further optimize the above technical solution, the outer wall of the regulating tube 4 has rotational friction texture.

[0056] In this embodiment, the air inlet 21 is an elongated hole, and the elongated hole is in the same direction as the axis of the air supply pipe 2.

[0057] The operating principle of this embodiment is the same as that of Embodiment 1, and will not be repeated here. Additionally, when it is necessary to adjust the air supply volume, simply turn the regulating pipe 4 to adjust the coverage of the regulating pipe 4 over the air supply port 21, thereby making the adjustment.

[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
