Description

Technical Field

[0001] This utility model relates to odor treatment equipment, and more particularly to an observation window for an odor treatment box. Background Technology

[0002] After the smoke and dust generated during tobacco processing are removed, they pass through odor treatment equipment. Through plasma reaction, photochemical reaction and three-stage water washing, the odors are removed before being released into the atmosphere to protect the ecological environment.

[0003] In actual use, each odor treatment system has three-stage water washing and cleaning tanks, and is equipped with four liquid level detection sensors and corresponding observation windows. During the odor treatment process, the water quality gradually becomes turbid, and impurities adhere to the observation windows and liquid level sensors, affecting signal transmission and normal liquid level detection. Therefore, it is necessary to clean the observation windows regularly, and to check, clean or replace the liquid level sensors.

[0004] Currently, the installation structure of the liquid level sensor is as follows: a perforation is made in the top wall of the observation window, and the wires of the liquid level sensor inside the observation window are led out through the perforation in the top wall of the observation window; the outside of the observation window is covered by a cover plate, which is installed on the observation window with multiple screws. When it is necessary to clean the inside of the observation window, or to inspect, clean, or replace the liquid level sensor, the equipment must first be stopped, all circulating fluid inside the equipment must be drained, and then the multiple screws on the cover plate must be removed before the liquid level sensor inside the observation window can be inspected, cleaned, or replaced, and the inside of the observation window can be cleaned. This operation is labor-intensive, time-consuming, and wasteful. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an observation window for an odor treatment box, so as to facilitate the cleaning or maintenance of the inner wall of the observation window and the liquid level sensor.

[0006] This utility model is achieved through the following technical solution:

[0007] An observation window for an odor treatment box is provided. The odor treatment box includes a treatment box body, and an observation window is provided on one side of the treatment box body. The outer side of the observation window is sealed by a cover plate. The middle area of ​​the cover plate is a transparent panel. An inspection through hole is opened at the top of the observation window. An operating plate is provided in the inspection through hole. The operating plate includes an operating plate body and an insertion plate body arranged vertically. The insertion plate body can be inserted into the inspection through hole and is sealed with the inspection through hole. The part of the operating plate body protruding from the insertion plate body forms an overlapping part. The operating plate body overlaps the top surface of the observation window through the overlapping part. A guide hole is opened on the operating plate. The wire of the liquid level sensor in the observation window body is led out from the guide hole of the operating plate.

[0008] As a preferred embodiment of the observation window of the aforementioned odor treatment box, a sealing ring is embedded around the insertion plate, which seals the gap between the outer wall of the insertion plate and the inner wall of the inspection through hole at the top of the observation window.

[0009] As a preferred embodiment of the observation window of the aforementioned odor treatment box, both the operation plate and the insertion plate have rectangular cross-sections.

[0010] This invention has the following advantages over the prior art:

[0011] This utility model provides an observation window for an odor treatment box. An inspection through-hole is provided at the top of the observation window, and a removable, sealable operating plate is installed in the inspection through-hole. A guide hole is provided on the operating plate for the lead wire of the liquid level sensor to be led out. When cleaning of the observation window is required, or when the liquid level sensor needs to be inspected, cleaned, or replaced, simply pull out the operating plate without disassembling the cover. This greatly shortens maintenance time, improves maintenance efficiency, and allows maintenance without stopping the machine, thus saving water resources. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0017] See Figures 1 to 3This embodiment discloses an observation window for an odor treatment box. The odor treatment box includes a treatment box body 1, and an observation window 2 is provided on one side of the treatment box body 1. The outer side of the observation window 2 is sealed by a cover plate 3. The middle area of ​​the cover plate 3 is a transparent panel 13, which is a glass panel and can be glued and fixed to the cover plate 3. The cover plate 3 is connected to the observation window 2 around its perimeter by multiple screws 4. The top of the observation window 2 has an inspection through hole 5, and an operation plate 6 is provided in the inspection through hole 5. The operation plate 6 includes an operation plate body 7 and an insertion plate body 8 arranged vertically. The cross-section of the operation plate body 7 and the insertion plate body 8 is rectangular.

[0018] The insertion plate 8 fits perfectly into the inspection through hole 5 and seals with it. An annular groove is formed around the outer periphery of the insertion plate 8, and a sealing ring 9 is embedded within the groove. The sealing ring 9 seals the gap between the outer wall of the insertion plate 8 and the inner wall of the inspection through hole 5 at the top of the observation window 2. The portion of the operating plate 7 protruding from the insertion plate 8 forms an overlapping part. The operating plate 7 overlaps with the top surface of the observation window 2 through this overlapping part. A guide hole 10 is formed on the operating plate 6, through which the wire 12 of the liquid level sensor 11 inside the observation window 2 is led outwards.

[0019] In this embodiment, a large-sized inspection through-hole 5 is provided on the top wall of the observation window 2. An operating plate 6, capable of being sealed and removed, is installed in the inspection through-hole 5. When cleaning the observation window 2 is required, simply pull out the operating plate 6 and clean the inner wall of the observation window 2 through the inspection through-hole 5. Simultaneously, this embodiment provides a guide hole 10 in the operating plate 6, through which the wire 12 of the liquid level sensor 11 is led outwards. Pulling out the operating plate 6 allows the liquid level sensor 11 to be removed from the observation window 2 for inspection, cleaning, or replacement. Therefore, the observation window 2 provided in this embodiment allows for cleaning, inspection, cleaning, or replacement of the liquid level sensor 11 without removing the multiple screws 4 on the cover plate 3, and without disassembling the cover plate 3. This significantly shortens maintenance time, improves maintenance efficiency, and saves water resources by eliminating the need to stop the machine or drain water from the equipment.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
