[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] See also Figure 1A humidifier clean water auxiliary noise reduction device includes a mounting frame 1, a noise reduction box 2 is arranged on the mounting frame 1, an operation window is arranged on one side of the noise reduction box 2, the operation window is provided with an isolation door 3 that can be opened, and an operation hole 4 is provided on the isolation door 3, so that a person can reach into the noise reduction box 2 for operation. By setting a noise reduction box, and opening an operation window on the noise reduction box, an isolation door 3 is arranged in the operation window, and an operation hole 4 is arranged on the isolation door 3; the openable isolation door 3 is convenient for placing the tested product, and the operation hole 4 is convenient for the staff to reach in with their hands to perform corresponding operations. The isolation door 3 and the noise reduction box can reduce the outward transmission of noise and the outward expansion of water vapor, so that the water vapor stays in the noise reduction box, thereby significantly reducing the probability of hearing loss of the staff, so that the working environment can be greatly improved. Preferably, there are two operation holes 4.
[0019] See also Figure 1 Preferably, the inner wall of the noise reduction box 2 is covered with sound-insulating absorbent cotton. By avoiding laying sound-insulating absorbent cotton inside the box, the noise can be further reduced and the hearing of the staff can be better protected.
[0020] See also Figure 1 Preferably, the isolation door 3 is slidably mounted at the operating window and can be moved up and down to open and close, or can be moved left and right to open and close. The isolation door 3 is designed to be movable to open, which can reduce the space occupied by the device compared to rotating to open, and helps to reduce the occupied space of the device.
[0021] See also Figure 1 Preferably, the isolation door 3 is driven to open by a driving member, the driving member is installed outside the box, and the driving member is in transmission cooperation with the isolation door 3. This assembly method can protect the driving member, avoid using it in a high humidity environment, and extend the service life of the driving member.
[0022] See also Figure 1 Preferably, the driving member is a cylinder 5, the movable part of the cylinder 5 is connected to a connecting block 6, the connecting block 6 is connected to the isolation door 3, and the two sides of the operating window are respectively provided with guide grooves, and the two sides of the isolation door 3 are respectively trapped in the corresponding guide grooves. The cylinder 5 is preferably a rodless cylinder 5, the movable part of the rodless cylinder 5 is a slider, and the slider is connected to the connecting block 6, so that the isolation door 3 can be driven to move along the guide groove under the push of the slider of the rodless cylinder 5 to open or close the operating window.
[0023] Preferably, the driving member is a motor, a lead screw and a nut. The motor is fixed to the outside of the noise reduction box 2. The output shaft of the motor is connected to the lead screw. The nut is passed through the lead screw. The nut is connected to a connecting block 6. The connecting block 6 is connected to the isolation door 3. Guide grooves are provided on both sides of the operation window. The two sides of the isolation door 3 are respectively trapped in the corresponding guide grooves. The motor drives the lead screw to rotate. Since the nut is limited by the connecting block 6, the nut and the lead screw rotate relative to each other, which is then converted into a linear movement of the nut, which drives the isolation door 3 to move linearly to open the isolation door 3, so that the isolation door 3 can be opened and closed, which is convenient for putting in and taking out products.
[0024] See also Figure 1 Preferably, the two guide grooves are respectively arranged on the upper and lower sides of the operating window, guiding the isolation door 3 to open and close the operating window along the left and right directions; or, the two guide grooves are respectively arranged on the left and right sides of the operating window, guiding the isolation door 3 to open and close the operating window along the vertical direction.
[0025] See also Figure 1 Preferably, a control button 7 is provided on the mounting frame 1 at a position outside the noise reduction box 2 and opposite to the isolation door 3. The control button 7 is communicated with the drive element to control the opening and closing of the isolation door 3. It should be noted that the circuit control of the motor or cylinder 5, etc., etc. all use mature existing technologies, which are described in detail here without specific protection requirements. There are three control buttons 7, including two start buttons and an emergency stop button. Two hands are required to press a start button respectively so that the drive element can work to drive the isolation door 3 to open.
[0026] See also Figure 1 Preferably, the isolation door 3 is made of glass or transparent plastic. It is convenient to observe the situation inside the noise reduction box so as to accurately clean the product.
[0027] Preferably, the isolation door 3 is hinged to one side of the operating window, and the isolation door 3 is opened or closed by a driving member around a hinge point. Although the isolation door 3 is installed by hinges, the installation is simple, but the staff must pay attention to avoid hitting the isolation door 3 when opening and closing the isolation door 3.
[0028] The utility model has the following working principle:
[0029] When the product needs to be cleaned, first open the isolation door, then put the product to be cleaned into the noise reduction box, then close the isolation door, and then extend your hand into the noise reduction box through the operation hole, hold the corresponding tool (such as an air gun or a large-flow air pipe) to perform the cleaning operation; after completing the cleaning, extend both hands from the operation hole, then open the isolation door, take out the product, and clean the next product.
[0030] The specific effects are shown in the following table:
[0031] The following table is a collection table of noise conditions of the plant's real line without the introduction of the utility model device:
[0032]
[0033] The following table is a collection table of noise conditions of some factory production lines that have introduced the utility model device:
[0034]
[0035]
[0036] From the above table, we can know that the main causes of noise are:
[0037] 1. In the process of sealing the boxes, the noise level was 74dB before the boxes were sealed and 85dB during the sealing process. The change in the numbers shows that the sound of the tape will increase the noise level by about 10dB (refer to the data of the points 2#-3F5);
[0038] 2. When using an air gun to clean machine dust and plastic chips on site: for example, the working noise without blowing is measured at 74dB and the working noise is measured at 89dB (about 3m away from the sound source). The digital changes show that the air sound of the air gun will increase the noise by about 15dB (refer to the point data of 2#-3F No. 3);
[0039] 3. In addition to the above two types of sound sources 1 and 2, there is another larger sound source on site, which has a greater impact on the overall production environment of the workshop; the humidifier water blowing cleaning process, for example, the working noise without blowing is measured at 74dB and the working noise is measured at 105dB. The digital changes show that the water blowing sound of the air gun will increase the noise by about 30dB (point data of 2#-2F No. 2).
[0040] After introducing the auxiliary noise reduction device:
[0041] 1. Comparison of data before and after improvement (105.6dB before improvement, 74.6dB after improvement, which can reduce the noise source diffusion by about 30dB);
[0042] 2. Comparison of noise environment between workshops (the average noise value of 2#3F according to the original data is about 76.42dB, and the average noise value of 2#2F according to the original data is about 87.6dB. After improvement, the overall noise reduction average is about 76dB, which can reduce the noise source diffusion of 11dB);
[0043] 3. As the second data shows, the noise value of the humidification production workshop on the second floor is close to the average noise value of the purifier production workshop on the third floor after the silent transformation. The data proves that silent transformation can effectively reduce the high-decibel noise diffusion of the water blowing process and improve the noise level of the floor.
