Abstract
Description
Technical Field
[0001] This utility model relates to grate structure, and in particular to a gradual air regulating device for grate air chamber. Background Technology
[0002] When incinerating combustibles such as garbage, incineration equipment with an internal grate structure is required. The grate is the core component of the incineration equipment, which is mainly used to support fuel (such as solid waste, biomass, etc.) and achieve efficient and complete combustion of fuel by controlling air flow, fuel movement and combustion rate.
[0003] In order for the fuel above the grate to burn, an air chamber needs to be installed below the grate. An air inlet is opened on the side wall of the air chamber to introduce fresh air into the air chamber and provide sufficient oxygen for combustion.
[0004] Theoretically, the combustion can be controlled by adjusting the air intake at the air inlet. In traditional structures, workers attempt to adjust the air volume by adjusting the distance between the baffle and the air chamber inlet. However, this adjustment method only has two states: fully closed (corresponding to 0 air volume) and fully open (corresponding to maximum air volume). Therefore, it cannot actually achieve the purpose of adjusting the air intake.
[0005] If the drive structure of the adjusting baffle is redesigned so that it moves on the plane where the air chamber inlet is located, the air intake volume can be adjusted by adjusting the area covered by the baffle. However, this requires a lot of work and is relatively expensive, and the parts related to the drive structure of the baffle also need to be modified accordingly.
[0006] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention
[0007] The present invention addresses the aforementioned shortcomings of the existing technology by proposing a gradual air adjustment device for the grate air chamber that is simple in structure, ingenious in design, reasonable in layout, and easy and convenient to operate.
[0008] The technical solution of this utility model is: a gradual air regulating device for a grate air chamber, characterized in that: the air regulating device includes a baffle 2 located outside the opening of the air chamber 1, a connecting rod 3 is provided at the center of one side of the baffle 2, and an end 4 located outside the grate is provided at the end of the connecting rod 3. The connecting rod 3 is movably connected to a guide sleeve 5, and the guide sleeve 5 is installed on the grate body 6.
[0009] A locking bolt 7 is threaded onto the guide sleeve 5. The locking bolt 7 is distributed radially along the connecting rod 3, and the end of the locking bolt 7 can abut against the outer wall of the connecting rod 3.
[0010] The connecting rod 3 has scale lines drawn on it.
[0011] The baffle 2 is connected to an air regulating block 8 on the side away from the connecting rod 3, and the air regulating block 8 is in the shape of a frustum.
[0012] Compared with the prior art, this utility model has the following advantages:
[0013] This type of grate air chamber uses a gradual air regulating device, which is simple in structure, ingenious in design, and reasonable in layout. It addresses the problems existing in the use of traditional grate air chamber regulating devices by designing a special structure. It sets a frustum-shaped air regulating block at the air outlet. By adjusting the relative position of the air regulating block and the air outlet, the cross-sectional area of the air passage can be adjusted, thereby conveniently and quickly achieving effective control and adjustment of the air volume. Moreover, this adjustment is verified in advance, which can achieve precise control of the air volume, thereby achieving the purpose of precisely controlling the degree of combustion of the grate.
[0014] At the same time, this gradual air conditioning device has a simple manufacturing process and low manufacturing cost, so it can be said that it has many advantages and is particularly suitable for promotion and application in this field, with a very broad market prospect.

[0018] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 3 As shown: A gradual air regulating device for a grate air chamber includes a baffle 2 located outside the opening of the air chamber 1. A connecting rod 3 is disposed at the center of one side of the baffle 2, and an end cap 4 located outside the grate is disposed at the end of the connecting rod 3. The connecting rod 3 is movably connected to a guide sleeve 5, and the guide sleeve 5 is installed on the grate body 6.
[0019] A locking bolt 7 is threaded onto the guide sleeve 5. The locking bolt 7 is distributed radially along the connecting rod 3, and the end of the locking bolt 7 can abut against the outer wall of the connecting rod 3.
[0020] The connecting rod 3 has scale lines drawn on it.
[0021] The baffle 2 is connected to an air regulating block 8 on the side away from the connecting rod 3, and the air regulating block 8 is in the shape of a frustum.
[0022] The working process of the gradual air adjustment device for the grate air chamber in this embodiment of the utility model is as follows: When it is not necessary to supply air to the air chamber 1, push the connecting rod 3 so that the baffle 2 presses against the outer wall of the opening of the air chamber 1, and rotate the locking bolt 7 to lock the connecting rod 3. At this time, the baffle 2 completely closes the opening of the air chamber 1.
[0023] When air needs to be supplied to the air chamber 1, the operator loosens the locking bolt 7 to restore the freedom of the connecting rod 3, and then holds the end 4 and pulls the connecting rod 3 outward. The baffle 2 leaves the opening of the air chamber 1. However, since the baffle 2 is also connected to the air regulating block 8, the air regulating block 8 forms a occupant at the opening of the air chamber. Therefore, air can only enter the air chamber 1 through the gaps around the air regulating block 8.
[0024] Since the air regulating block 8 is shaped like a frustum, the greater the distance between the baffle 2 and the opening of the air chamber 1, the larger the flow area that air can pass through. Therefore, the flow area can be adjusted by adjusting the distance between the baffle 2 and the opening of the air chamber 1.
[0025] During the adjustment process, staff can determine the current ventilation cross-sectional area by referring to the scale lines on link 3. The scale lines on link 3 are established based on experimental data after prior testing. For example, when the pull-out length of link 3 is 50mm, the corresponding ventilation cross-sectional area is 30,000 mm². 2 Then simply mark 30,000 mm at 50 mm. 2 This is to make it easier for staff to operate the equipment intuitively.
