A waste gas collection and treatment cabinet

Abstract

This utility model discloses a waste gas collection and treatment cabinet, which includes a collection cabinet, a treatment chamber, an adsorption element, a fan, and a power supply. The collection cabinet has a loading chamber with an open air inlet. The treatment cabinet has a waste gas passage and a negative pressure chamber, the waste gas passage being connected to the loading chamber, and the negative pressure chamber having an air outlet. The adsorption element is detachably mounted on the waste gas passage. The fan is fixedly mounted on the air outlet. The power supply is electrically connected to the fan. In this waste gas collection and treatment cabinet, the loading chamber can be used to place high-temperature metal workpieces that have undergone quenching treatment. When the fan is turned on, it creates negative pressure in the negative pressure chamber, causing the waste gas in the loading chamber to enter the waste gas passage, then pass through the adsorption element into the negative pressure chamber, and finally exit the waste gas collection and treatment cabinet through the air outlet. When the waste gas passes through the adsorption element, harmful gases in the waste gas can be adsorbed and treated, thereby significantly reducing the content of harmful gases in the air.

Description

Technical Field

[0001] This utility model relates to the field of waste gas collection technology, and in particular to a waste gas collection and treatment cabinet. Background Technology

[0002] In the field of metal processing, some small workpieces (such as bearings) usually need to be processed by turning, milling, cutting, grinding, quenching and other processes. After processing, small workpieces are usually placed in batches on pallets or hangers to dissipate heat and collect residual liquid lubricating or protective oil. However, during the placement process, because the workpieces still have a high temperature and the liquid lubricating or protective oil itself is volatile, these workpieces will still emit a lot of exhaust gas. The exhaust gas will seriously pollute the work space and harm the physical and mental health of the workers.

[0003] Therefore, it is necessary to provide an exhaust gas collection and treatment cabinet to solve the above problems. Utility Model Content

[0004] A waste gas collection and treatment cabinet, comprising: The collection cabinet has an internal storage chamber with an air inlet. The processing cabinet is equipped with an exhaust gas passage and a negative pressure chamber. The exhaust gas passage is connected to the loading chamber, and the negative pressure chamber is provided with an air outlet. An adsorption element, detachably mounted on the exhaust gas passage; and The fan is fixedly installed on the air outlet.

[0005] In one embodiment, the cargo cavity is provided with one or more partitions.

[0006] In one embodiment, the bottom of the cargo cavity and the partition are arranged at a predetermined angle α.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is considered to be "connected" or "connected" to another element, it can be directly connected to the other element or there may be an intervening element. The terms "upper," "lower," "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0018] The exhaust gas collection and treatment cabinet will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Please see Figure 1 One embodiment of the exhaust gas collection and treatment cabinet includes a collection cabinet 10, a treatment cabinet 20, an adsorption element 30, and a fan 40.

[0020] The collection cabinet 10 has an internal storage cavity 11 for holding high-temperature metal workpieces after quenching. The collection cabinet 10 is equipped with an air inlet 12, through which the storage cavity 11 communicates with the outside environment. Outside air can enter the storage cavity 11 through the air inlet 12.

[0021] It should be understood that the shape and size of the air inlet 12 are variable. It can be a rectangle, a square or other irregular shape. It can even be a slit. As long as the slit can serve as an air inlet, it can serve as the air inlet 12 of this utility model.

[0022] Optionally, the air inlet 12 can be located at any position on the housing of the collection cabinet 10, including but not limited to the front, side, back or top.

[0023] In this embodiment, the air inlet 12 is located on the front of the collection cabinet 10 and is rectangular. At this time, the air inlet 12 also serves as a feeding port, and people can conveniently place the workpiece into the loading cavity 11 through the air inlet 12.

[0024] Preferably, the size of the air inlet 12 can be controlled by providing a shield on the air inlet 12.

[0025] Optionally, the collection cabinet 10 can be in the shape of a cuboid, cube, truncated pyramid, cylinder, or other shapes. In this embodiment, the collection cabinet 10 is in the shape of a cuboid.

[0026] In another implementation, please refer to Figure 2 The loading cavity 11 is provided with one or more partitions 13. By providing one or more partitions 13, each partition 13 can be used to support the high-temperature metal workpiece after quenching, thereby greatly improving the space utilization rate of the loading cavity 11 and helping to reduce the unit energy consumption of waste gas collection.

[0027] Preferably, please refer to Figure 3 The bottom surface of the loading cavity 11 and the partition 13 are set at a predetermined angle α with the horizontal plane. By setting the angle α, the residual liquid grease on the surface of the workpiece can eventually accumulate at the lowest point of the loading cavity 11 under the action of gravity, thereby facilitating the collection of liquid grease.

[0028] Optionally, 1°≤a≤30°, by limiting the range of the tilt angle a, can ensure that the liquid grease accumulates at the lowest point of the loading cavity 11.

[0029] Preferably, the inclination angle α is within the range of 3° ≤ a ≤ 8°, which is moderate and can prevent the workpiece from sliding on the bottom surface of the loading cavity 11 or the partition 13. In this embodiment, α is 5°.

[0030] Preferably, a guide hole (not shown in the figure) is provided at the lowest point of the loading cavity 11, so that the collected liquid grease can be collected through the guide hole.

[0031] The processing cabinet 20 is equipped with an exhaust gas passage 21 and a negative pressure chamber 22. The exhaust gas passage 21 is connected to the loading chamber 11.

[0032] exist Figure 3 In the embodiment shown, the exhaust gas passage 21 is arranged in a B-shape, and it is connected to the loading cavity 11 through the protruding part.

[0033] The adsorption element 30 is disposed on the exhaust gas channel 21. The edge of the adsorption element 30 is sealed to the exhaust gas channel 21. The adsorption element 30 is provided with adsorption material, which can adsorb harmful gases in the exhaust gas. The negative pressure chamber 22 is provided with an air outlet.

[0034] Optionally, the adsorbent material includes, but is not limited to: expanded graphite, zeolite powder, activated carbon, and oil-absorbing felt.

[0035] In this embodiment, the processing cabinet 20 is located below the collection cabinet 10, and a container is provided in the exhaust gas channel 21. The liquid grease collected at the bottom of the loading chamber 11 can flow into the container under the action of gravity, which facilitates the collection of liquid grease.

[0036] It should be understood that the treatment cabinet 20 and the collection cabinet 10 can be arranged horizontally or vertically adjacent to each other. When the treatment cabinet 20 and the collection cabinet 10 are arranged vertically adjacent to each other, the treatment cabinet 20 can be located above or below the collection cabinet 10, as long as the exhaust gas can enter the exhaust gas passage 21 under negative pressure.

[0037] The fan 40 is fixedly installed at the air outlet inside the negative pressure chamber 22. The fan 40 can be driven by an external power supply connected by a wire. When the fan 40 is started, it can discharge air to the outside through the air outlet, thereby generating negative pressure in the negative pressure chamber 22. The negative pressure then drives the waste gas in the loading chamber 11 into the waste gas passage 21, and further into the negative pressure chamber 22 through the adsorption element 30.

[0038] In this embodiment, the collection cabinet 10 and the treatment cabinet 20 are designed as an integral unit. The waste gas collection and treatment cabinet as a whole includes a fixedly connected collection cabinet 10 and a treatment cabinet 20.

[0039] In another embodiment, the collection cabinet 10 and the processing cabinet 20 are designed separately, with one processing cabinet 20 corresponding to multiple collection cabinets 10. In the non-operational state, the collection cabinet 10 and the processing cabinet 20 can be physically separated, allowing the collection cabinet 10 to move freely. Therefore, by moving the collection cabinet 10 closer to the quenching pool, it is convenient to place high-temperature workpieces in the loading cavity 11. When exhaust gas collection and treatment is required, the collection cabinet 10 and the processing cabinet 20 are combined to connect the loading cavity 11 with the exhaust gas channel 21, and the fan 40 is started to perform the exhaust gas collection and treatment function.

[0040] In another embodiment, the exhaust gas collection and treatment cabinet also includes a built-in power supply 50, which is fixedly installed on the exhaust gas collection and treatment cabinet and electrically connected to the fan 40. The built-in power supply 50 is used to drive the fan 40 to rotate, so that negative pressure is continuously generated in the negative pressure chamber 22.

[0041] In this embodiment, the built-in power supply 50 is disposed inside the negative pressure chamber 22.

[0042] Preferably, the built-in power supply 50 is a rechargeable power supply. After charging, the rechargeable power supply does not require an external fixed power supply, making the exhaust gas collection and treatment cabinet easy to move.

[0043] In this embodiment, a caster assembly is provided at the bottom of the exhaust gas collection and treatment cabinet, thereby facilitating the movement of the exhaust gas collection and treatment cabinet.

[0044] The aforementioned exhaust gas collection and treatment cabinet has a loading chamber 11 for placing high-temperature metal workpieces that have undergone quenching treatment. When the fan 40 is turned on, the fan 40 can generate negative pressure in the negative pressure chamber 22. The negative pressure allows the exhaust gas in the loading chamber 11 to enter the exhaust gas channel 21, and then enter the negative pressure chamber 22 through the adsorption element 30. Finally, it is discharged from the exhaust gas collection and treatment cabinet through the air outlet. When the exhaust gas passes through the adsorption element 30, the harmful gases in the exhaust gas can be adsorbed and treated, thereby significantly reducing the content of harmful gases in the air.

[0045] The following are specific examples. Example

[0046] Please see Figure 1 This embodiment provides a waste gas collection and treatment cabinet, including a collection cabinet 10, a treatment cabinet 20, an adsorption element 30, and a fan 40.

The treatment cabinet 20 has a waste gas passage 21 and a negative pressure chamber 22, with the waste gas passage 21 communicating with the loading chamber 11. The adsorption element 30 is mounted on the waste gas passage 21. The fan 40 is mounted on the air outlet and is driven by an external power source connected to a wire.

[0047] In this embodiment, the collection cabinet 10 and the processing cabinet 20 are rectangular parallelepipeds, with the air inlet 12 located on the front of the collection cabinet 10 and the collection cabinet 10 located above the processing cabinet 20.

[0048] The aforementioned exhaust gas collection and treatment cabinet has a loading chamber 11 for placing high-temperature metal workpieces that have undergone quenching treatment. When the fan 40 is turned on, the fan 40 can generate negative pressure in the negative pressure chamber 22. The negative pressure allows the exhaust gas in the loading chamber 11 to enter the exhaust gas channel 21, and then enter the negative pressure chamber 22 through the adsorption element 30. Finally, it is discharged from the exhaust gas collection and treatment cabinet through the air outlet. When the exhaust gas passes through the adsorption element 30, the harmful gases in the exhaust gas can be adsorbed and treated, thereby significantly reducing the content of harmful gases in the air. Example

[0049] Please see Figure 2 The exhaust gas collection and treatment cabinet provided in this embodiment is similar to the exhaust gas collection and treatment cabinet provided in Embodiment 1, except that: multiple partitions 13 are provided in the loading cavity 11.

[0050] The aforementioned exhaust gas collection and treatment cabinet, by setting multiple partitions 13, each of which can be used to support high-temperature metal workpieces after quenching, greatly improves the space utilization rate of the loading cavity 11 and helps to reduce the unit energy consumption of exhaust gas collection. Example

[0051] Please see Figure 3 The exhaust gas collection and treatment cabinet provided in this embodiment is similar to the exhaust gas collection and treatment cabinet provided in Embodiment 1, except that the bottom of the loading chamber 11 and the partition 13 are set at a predetermined angle α with the horizontal plane.

[0052] The aforementioned exhaust gas collection and treatment cabinet, by setting an inclination angle α, allows residual liquid grease on the workpiece surface to eventually accumulate at the lowest point of the loading cavity 11 under the action of gravity, thereby facilitating the collection of liquid grease.

[0056] In the non-operational state, the above-mentioned waste gas collection and treatment cabinet 10 and the treatment cabinet 20 can be physically separated, allowing the collection cabinet 10 to move freely. Therefore, by moving the collection cabinet 10, it can be brought closer to the quenching pool, making it convenient to place high-temperature workpieces in the loading cavity 11. When waste gas collection and treatment is required, the collection cabinet 10 and the treatment cabinet 20 are combined to connect the loading cavity 11 with the waste gas channel 21, and the fan 40 is started to perform the waste gas collection and treatment function.
