Description

Technical Field

[0001] The utility model belongs to the technical field of tape production, and particularly relates to an exhaust gas absorption device for a workshop in the tape production process. Background Art

[0002] Tape is a common bonding tool. In the process of tape production, the chemical substances used will generate waste gas. In the tape production process, adhesives and other chemical raw materials used may release volatile organic compounds during heating. These substances include, but are not limited to, benzene, toluene, xylene and ethyl acetate. The waste gas contains various harmful components, and these components have certain toxicity and irritation. The direct emission of untreated waste gas will have an adverse impact on the environment and human health, such as forming air pollution and affecting air quality.

[0003] The existing authorized publication number is CN215463099U, which discloses an exhaust gas treatment device for the tape production process, including an exhaust gas absorption device. An inlet pipe is arranged on one side of the exhaust gas absorption device, and a fan is fixedly connected to one side of the exhaust gas absorption device; an absorption mechanism, the absorption mechanism includes activated carbon and a first mounting plate. The activated carbon is slidably mounted inside the exhaust gas absorption device. A first mounting plate is fixedly connected inside the exhaust gas absorption device. First chutes are opened on both sides inside the first mounting plate. Sliders are slidably mounted inside the first chutes. One side of the slider is movably connected to a connecting rod. Through the setting of the absorption mechanism, the gas introduced into the device can be better absorbed. Through the mutual filtration between the activated carbon and the waste gas, the device is more efficient during use and more convenient during the replacement process inside the device, increasing the stability and efficiency of the device. However, only the absorption of waste gas by activated carbon is involved in the above exhaust gas treatment device for the tape production process. It is very difficult to fully absorb various waste gases generated during the tape production process only through the adsorption of activated carbon. Therefore, it is necessary to provide an exhaust gas absorption device for a workshop in the tape production process to solve the above problems. Summary of the Utility Model

[0004] The technical content of the utility model is to provide an exhaust gas absorption device for a workshop in the tape production process.

[0005] To solve the above problems, the utility model provides a workshop waste gas absorption device during the tape production process, which includes a collection bin. A heating bin is installed at the bottom of the collection bin. A liquid injection port is opened at the top of the heating bin, and a liquid discharge port is opened at the front. Sealing plugs are installed in both the liquid injection port and the liquid discharge port. A heating base is installed inside the heating bin. An installation cover is installed on the top of the collection bin through an installation ring. The installation cover is evenly divided into left and right parts. An exhaust gas absorber is installed on the top of the installation cover. A guide pipe is installed at the bottom of the exhaust gas absorber. A sealing insertion ring is installed on the left side of the right half of the installation cover. Four groups of exhaust pipes are symmetrically installed at the bottom of the installation cover.

[0006] As a further solution of the utility model, a threaded connection structure is installed at the top of the heating bin, and a threaded connection groove adapted to it is opened at the bottom of the collection bin, so that the collection bin can be fixedly installed on the top of the collection bin by means of rotational connection.

[0007] As a further solution of the utility model, a sealing slot adapted to the sealing insertion ring is opened at the right edge of the left half of the installation cover. Two groups of fixing bolts are installed at the top and bottom of the installation cover. The fixing bolts pass through the left half of the installation cover and the sealing insertion ring. The exhaust gas absorber is fixedly installed on the top of the installation cover through the fixing bolts. An installation groove adapted to the guide pipe installed at the bottom of the exhaust gas absorber is opened in the middle of the top of the installation cover. The guide pipe is communicated with the internal space of the installation cover. The installation cover is designed as a quick-disassembly structure symmetrical left and right to facilitate the quick replacement of absorption substances such as activated carbon therein.

[0008] As a further solution of the utility model, a group of installation rings are installed on the outer side of the top of the collection bin and the outer side of the bottom of the installation cover respectively. The two groups of installation rings are connected by six groups of symmetrical fixing bolts. Two groups of through grooves are opened at the bottom of the left and right parts of the installation cover respectively, and the exhaust pipes are fixedly installed therein. Filter holes are provided at the top of the exhaust pipes, and the diameter of the filter holes is smaller than the diameter of absorption substances such as activated carbon to prevent the absorption substances such as activated carbon from entering the exhaust pipes.

[0009] As a further solution of the utility model, the heating base is fixedly installed on the inner bottom surface of the heating bin, and the absorption liquid for absorbing waste gas can be heated through the heating base.

[0010] Compared with the related technology, a workshop waste gas absorption device during the tape production process provided by the utility model has the following beneficial effects:

[0011] 1. The utility model sets the installation cover as a detachable structure that is symmetrical left and right. Adsorbents such as activated carbon for preliminary absorption and treatment of waste gas can be filled into the installation cover, so as to preliminarily adsorb the waste gas generated in the tape production process absorbed by the waste gas absorber. Subsequently, the waste gas enters the collection chamber through the exhaust pipe. Waste gas absorption liquid can be added to the heating chamber installed at the bottom of the collection chamber. The heating seat set in the heating chamber can heat the waste gas absorption liquid, so that the waste gas absorption liquid evaporates and fully absorbs the waste gas in the collection chamber. Compared with the comparative case, this device can absorb the waste gas entering the collection chamber more fully.

[0012] 2. The utility model installs a sealing insertion ring at the left edge of the right half of the installation cover, and a sealing slot adapted to the sealing insertion ring is opened at the right edge of the left half of the installation cover. By inserting the sealing insertion ring into the sealing slot, the left and right parts of the installation cover can be assembled together. At this time, the connection between the left and right parts of the installation cover has good sealing performance, so that the waste gas entering the installation cover will not leak.

[0013] 3. The utility model is provided with filter holes at the top of the exhaust pipe, and the diameter of the filter holes is smaller than the diameter of absorbents such as activated carbon, so that the waste gas can enter the exhaust pipe while the absorbents such as activated carbon cannot enter the exhaust pipe, thereby preventing the absorbents such as activated carbon from entering the collection chamber and ensuring the absorption efficiency.

[0026] Preferably, a threaded connection structure is installed at the top of the heating bin 2, and a threaded connection groove adapted thereto is opened at the bottom of the collection bin 1, so that the collection bin 1 can be fixedly installed on the top of the collection bin 1 by means of rotational connection. At this time, the threaded connection structure is inside the threaded connection groove, so that there is good connection tightness between the collection bin 1 and the heating bin 2, preventing the waste gas in the collection bin 1 from leaking;

[0027] Preferably, a sealing slot adapted to the sealing insertion ring 9 is provided at the right edge of the left half of the mounting cover 6. By inserting the sealing insertion ring 9 into the sealing slot, the left and right parts of the mounting cover 6 can be assembled together. Before assembly, substances such as activated carbon that can absorb harmful components in the waste gas need to be filled into the interior of the mounting cover 6. Two groups of fixing bolts are installed at the top and bottom of the mounting cover 6. The fixing bolts pass through the left half of the mounting cover 6 and the sealing insertion ring 9, thereby fixedly installing the sealing insertion ring 9 in the sealing slot, and then the left and right parts of the mounting cover 6 can be fixedly assembled together. The waste gas absorber 7 is fixedly installed on the top of the mounting cover 6 through the fixing bolts. An installation slot adapted to the air duct 8 installed at the bottom of the waste gas absorber 7 is provided in the middle of the top of the mounting cover 6. The air duct 8 is communicated with the internal space of the mounting cover 6. Through the waste gas absorber 7, the waste gas in the air of the tape production workshop can be concentrated into the interior of the mounting cover 6. Subsequently, through the absorption substances such as activated carbon in the mounting cover 6, the waste gas can be preliminarily absorbed and filtered for subsequent further absorption treatment of the waste gas. The mounting cover 6 is designed as a quick-disassembly structure that is symmetric left and right. When it is necessary to replace the absorption substances such as activated carbon therein, first remove the waste gas absorber 7 from the top of the mounting cover 6, and then remove the four groups of fixing bolts installed at the top and bottom of the mounting cover 6 to disassemble the mounting cover 6, so that the absorption substances such as activated carbon therein can be quickly replaced;

[0028] Preferably, a mounting ring 5 is installed on the outer side of the top of the collection bin 1 and the outer side of the bottom of the mounting cover 6.

Two groups of through slots are provided at the bottom of the left and right parts of the mounting cover 6, and the exhaust pipes 10 are fixedly installed therein, so that the waste gas treated by the absorption substances such as activated carbon in the mounting cover 6 can enter the interior of the collection bin 1 through the four exhaust pipes 10. Filter holes are provided at the top of the exhaust pipes 10, and the diameter of the filter holes is smaller than the diameter of the absorption substances such as activated carbon, so that the waste gas can enter the exhaust pipes 10 while the absorption substances such as activated carbon cannot enter the exhaust pipes 10, thereby preventing the absorption substances such as activated carbon from entering the collection bin 1 and ensuring the absorption efficiency;

[0029] Preferably, the heating seat 4 is fixedly installed on the inner bottom surface of the heating chamber 2. Through the liquid injection port provided at the top of the heating seat 4, the absorption liquid for absorbing waste gas can be injected into the interior of the heating chamber 2. Subsequently, the heating seat 4 heats the heating chamber 2, causing the absorption liquid to volatilize, so that the waste gas in the collection bin 1 can be adsorbed, and the waste gas is dissolved in the absorption liquid and concentrated in the interior of the heating chamber 2. After the waste gas treatment process is completed, by removing the sealing plug 3 installed on the drain port, the absorption liquid inside the heating chamber 2 can be discharged, thereby realizing the absorption and transfer of waste gas.
