Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing equipment, and particularly relates to a smoking, filtering and smoke exhaust device for a mold injection workshop. Background Art

[0002] Plastic processing is the general term for various processes that convert synthetic resins or plastics into plastic products, and it is a relatively large production department in the plastics industry. In related technologies, plastic processing generally includes processes such as plastic batching, molding, and machining. Among them, plastic molding often uses the injection molding process. An injection molding machine uses a plastic molding mold to make various plastic products from thermoplastic or thermosetting plastics. During the injection molding process, solid plastic particles are heated into a liquid state and injected into the plastic molding mold. Since heating causes the plastic particles to volatilize, harmful gases such as styrene and toluene are generated, which are not only pungent but also harmful to the health of the workers in the injection workshop. Moreover, large particle impurities and dust are also generated during the injection molding process, and a smoke exhaust device is often installed in the injection workshop.

[0003] During the injection molding process, a large amount of harmful gases will quickly spread and permeate the entire area where the workbench is located. In the prior art, an air suction hood is generally set above the workbench. This method has a narrow operation range and cannot effectively remove the harmful gases in the space. Therefore, we propose a smoking, filtering and smoke exhaust device for a mold injection workshop to solve the above problems. Content of the Utility Model

[0004] The utility model specifically adopts the following technical solutions to achieve the above purposes:

[0005] A smoking, filtering and smoke exhaust device for a mold injection workshop, comprising:

[0006] A U-shaped cabin, on both sides of the front of the U-shaped cabin, installation pipes are communicated at equal intervals. An activated carbon rod is filled inside the installation pipe, and air inlet holes are evenly distributed on the surface of the installation pipe;

[0007] A fixed pipe is communicated in the middle of the U-shaped cabin. A ventilation pipe is communicated in the middle of the fixed pipe. One end of the ventilation pipe away from the fixed pipe is communicated with an installation box. The installation box is arranged outside the injection workshop, and a blower is installed on one side of the installation box away from the fixed pipe.

[0008] Further, one end of the installation pipe away from the U-shaped cabin is threadedly connected with a pipe cap.

[0009] Further, Z-shaped elastic pieces are fixedly arranged on the inner wall of the U-shaped cabin corresponding to the position of the installation pipe.

[0010] Further, the ventilation pipe is a PVC corrugated pipe.

[0011] Further, the top of the fixed pipe is communicated with an air chamber, and ventilation holes are evenly distributed on the front surface of the air chamber.

[0012] Further, air valves are installed on both sides of the fixed pipe body located in the ventilation pipe.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. Through the combined design of the C-shaped chamber, multiple installation pipes, and activated carbon rods, the present utility model can greatly improve the ability to remove harmful gases in the space around the workbench. The harmful gases generated during the injection molding process enter the C-shaped chamber through the installation pipes, are adsorbed by the activated carbon rods, then enter the installation box through the fixed pipe and the ventilation pipe, and finally the harmful gases are discharged from the workshop by the blower, thereby improving the safety and comfort of the working environment, with high practicability and worthy of widespread application and promotion.

Specific Embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0021] This application provides a smoking, filtering, and smoke exhaust device for a mold injection workshop, which is mainly used to solve the problem that in the prior art, an air suction hood is generally set above the workbench, and this method has a narrow operation range and cannot effectively remove harmful gases in the space, and provides the following technical solutions, which will be described in detail below in combination with Figure 1-Figure 4 for a detailed description:

[0022] A smoking, filtering, and smoke exhaust device for a mold injection workshop, comprising:

[0023] The U-shaped cabin 1 is connected with installation pipes 2 at equal intervals on both sides of the front surface. The inside of the installation pipes 2 is filled with activated carbon rods 3, and air inlets 201 are evenly distributed on the surface of the installation pipes 2;

[0024] The fixed pipe 4 is connected to the middle of the U-shaped cabin 1. The middle of the fixed pipe 4 is connected with a ventilation pipe 5. One end of the ventilation pipe 5 far away from the fixed pipe 4 is connected with an installation box 6. The installation box 6 is arranged outside the injection molding workshop, and a blower 7 is installed on one side of the installation box 6 far away from the fixed pipe 4.

[0025] More specifically, the specific use process and principle of the smoking, filtering and exhaust device in the injection molding workshop of this mold:

[0026] In the first step, the U-shaped cabin 1 is installed at the rear side of the top of the workbench, so that the installation pipes 2 extend to both sides of the workbench. The installation box 6 is arranged outside the injection molding workshop and is connected with the U-shaped cabin 1 through the ventilation pipe 5;

[0027] In the second step, the harmful gases generated during the injection molding process enter the U-shaped cabin 1 through the installation pipes 2, are adsorbed by the activated carbon rods 3, then enter the installation box 6 through the fixed pipe 4 and the ventilation pipe 5, and finally the blower 7 discharges the harmful gases out of the workshop.

[0028] It should be noted that the activated carbon rod 3 is a prior art and is a kind of granular activated carbon经过特殊加工和压缩的颗粒活性炭. It has a large surface area and many pores, so it has strong adsorption capacity and can be used in the fields of air purification, waste gas treatment, etc. to remove harmful gases and odors in the air.

[0029] The smoking, filtering and exhaust device in the injection molding workshop of this mold can greatly improve the ability to remove harmful gases in the space around the workbench through the combined design of the U-shaped cabin 1, multiple installation pipes 2 and activated carbon rods 3, thereby improving the safety and comfort of the working environment.

[0030] As Figure 4 shown, in some embodiments, one end of the installation pipe 2 far away from the U-shaped cabin 1 is threadedly connected with a pipe cap 202. More specifically, the function of the pipe cap 202 is to close the end of the installation pipe 2 to prevent the activated carbon rod 3 from leaving the installation pipe 2. Through threaded connection, it can ensure the tight connection between the pipe cap 202 and the installation pipe 2. When it is necessary to replace the activated carbon rod 3 or perform maintenance, the pipe cap 202 can be opened for operation.

[0031] As Figure 4As shown, in some embodiments, a Z-shaped elastic sheet 8 is fixedly provided on the inner wall of the C-shaped cabin 1 at the position corresponding to the installation pipe 2. More specifically, the Z-shaped elastic sheet 8 is a common hardware stamping part with elasticity and deformation ability. In this device, the Z-shaped elastic sheet 8 has two functions. First, it limits the activated carbon rod 3 to prevent it from being inserted too deep. Second, when the staff needs to replace the activated carbon rod 3, they can first squeeze the activated carbon rod 3 into the installation pipe 2 and then let go. Under the elastic force of the Z-shaped elastic sheet 8, the activated carbon rod 3 will slide out of the installation pipe 2, facilitating the staff to replace the activated carbon rod 3.

[0032] As Figure 1 shown, in some embodiments, the ventilation pipe 5 is a PVC corrugated pipe. More specifically, the PVC corrugated pipe is a pipe mainly made of rigid polyvinyl chloride. Its characteristic is that it is composed of a plastic pipe with a hollow sandwich between the inner and outer walls. The inner wall is smooth and the outer wall is trapezoidally corrugated. In the smoking, filtering, and smoke exhaust devices in the mold injection workshop, using the PVC corrugated pipe for the ventilation pipe 5 can improve the ventilation effect and durability. Its advantages are that it is lightweight and easy to install. At the same time, due to its special corrugated shape, the air circulation is smoother, which helps to improve the overall ventilation effect. In addition, the PVC material has the advantages of corrosion resistance, high temperature resistance, and pressure resistance, so it is not easily damaged during use and can ensure the long-term stable operation of the device.

[0033] As Figure 2 shown, in some embodiments, the top of the fixed pipe 4 is connected to an air chamber 9. The front of the air chamber 9 is evenly distributed with ventilation holes 901. On both sides of the ventilation pipe 5, air valves 401 are installed on the pipe body of the fixed pipe 4. More specifically, the blower 7 can both extract air and blow air. When the staff needs to ventilate the injection workshop, they can close the air valve 401 at the bottom of the fixed pipe 4 and open the air valve 401 on the upper side of the fixed pipe 4. At this time, the outside air can enter the fixed pipe 4 through the ventilation pipe 5 and finally escape from the ventilation holes 901 on the surface of the air chamber 9, further improving the air quality inside the injection workshop and providing a more comfortable and safe working environment for the staff.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
