Description

Technical Field

[0001] The utility model relates to the technical field of kiln filtration equipment, specifically, it is a combustion-supporting air filter for a kiln. Background Art

[0002] A kiln refers to a furnace used for firing ceramic wares. Generally made of bricks and stones, it can be made into various sizes according to needs, and can be operated with combustible gas, oil or electricity. When a kiln is in use, a combustion-supporting air device is required. However, in a kiln that needs to dry the glaze surface, in the heating pipeline of the traditional combustion-supporting air device, rust and other impurities that affect the glaze surface effect of the product are likely to appear. When the combustion-supporting air is input into the kiln, rust and other impurities are likely to fall onto the glaze surface, which easily leads to a large number of defective products in the products within a kiln line. Therefore, many enterprises will stop using combustion-supporting air heating to reduce the risk of dirt falling caused thereby, but this will cause the energy consumption of the kiln to increase. Content of the Utility Model

[0003] In order to overcome the defects existing in the prior art, the utility model provides a combustion-supporting air filter for a kiln to solve the above problems in the prior art.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a combustion-supporting air filter for a kiln, including a box body. An air inlet is arranged on one side of the box body, and an air outlet is arranged on the other side. A filter cavity communicating with the air inlet and the air outlet is arranged inside the box body. Multiple groups of filter components are arranged inside the filter cavity. The multiple groups of filter components are distributed up and down and the head and tail of each adjacent group of filter components are connected to each other, so that the multiple groups of filter components form a wave shape. The multiple groups of filter components are detachably installed inside the box body.

[0005] Further, a frame body is arranged inside the box body. An opening is arranged on one side of the frame body, and a cover plate is covered on the opening. Each of the multiple groups of filter components includes a first filter core and a second filter core. One sides of the first filter core and the second filter core are connected to each other, so that the first filter core and the second filter core form a V-shaped distribution. The first filter core and the second filter core are slidably arranged on the frame body, so that the first filter core and the second filter core can slide out from the opening.

[0006] More specifically, first slide rail grooves and second slide rail grooves are arranged on both sides of the frame body. Both sides of the first filter core are inserted into the first slide rail grooves on both sides, and both sides of the second filter core are inserted into the second slide rail grooves on both sides. The first slide rail grooves and the second slide rail grooves communicate with the opening.

[0007] Further, a first conical box communicating with the filtering chamber is provided on one side of the box body, and a second conical box communicating with the filtering chamber is provided on the other side. The air inlet mounting seat is on the first conical box, and the air outlet mounting seat is on the second conical box.

[0008] More specifically, butterfly valves are installed in both the air inlet and the air outlet, and pressure gauges are installed in both the air inlet and the air outlet.

[0009] The beneficial effects of the present utility model are as follows: By arranging the filtering components in a wavy arrangement inside the box body, when the hot air with impurities passes through, filtration is carried out, preventing rust and other impurities that affect the glaze effect of the product from being output to the kiln, resulting in defects in the glaze of the product. Moreover, the filtering components arranged in a wavy shape can increase the filtering surface, increase the ventilation area, and improve the filtering effect. At the same time, the filtered impurities are likely to further fall to the lower end inside the box body on the surface of the filtering components arranged in a wavy shape, thus facilitating the cleaning of the impurities. Since multiple groups of the filtering components can be disassembled from the box body, it is further convenient to clean the impurities on the surfaces of multiple groups of the filtering components. The overall structure has a good filtering effect and is easy to clean, and is suitable for the popularization of the combustion-supporting air of the kiln. Description of the Drawings

Specific Embodiments

[0015] The following further describes the specific embodiments of the present utility model in conjunction with the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] Combined with Figures 1 to 4A kind of combustion-supporting air filter for a kiln furnace shown in the figure includes a box body 1. An air inlet 5 is arranged on one side of the box body 1, and an air outlet 6 is arranged on the other side. A filter cavity communicating with the air inlet 5 and the air outlet 6 is arranged inside the box body 1. Multiple groups of filter components are arranged inside the filter cavity. The multiple groups of filter components are distributed up and down and the head and tail of each adjacent group of filter components are connected to each other, so that the multiple groups of filter components form a wavy shape. The multiple groups of filter components are detachably installed inside the box body 1. In this embodiment, the filter components arranged in a wavy pattern are arranged inside the box body 1, so that the hot air with impurities is filtered after passing through, preventing rust and other impurities that affect the glaze effect of the product from being output to the kiln furnace and causing defects in the glaze of the product. Moreover, the filter components arranged in a wavy pattern can increase the filter surface, increase the ventilation area, and improve the filtering effect. At the same time, the filtered impurities are likely to further fall to the lower end inside the box body 1 on the surface of the filter components arranged in a wavy pattern, thus facilitating the cleaning of the impurities. Since the multiple groups of filter components can be detached from the box body 1, it is further convenient to clean the impurities on the surface of the multiple groups of filter components. The overall structure has a good filtering effect and is convenient to clean, which is suitable for the popularization of the combustion-supporting air of the kiln furnace.

[0017] In this embodiment, a frame body 9 is arranged inside the box body 1. An opening 14 is arranged on one side of the frame body 9, and a cover plate 2 is covered on the opening 14. Multiple groups of filter components all include a first filter core 10 and a second filter core 11. One side of the first filter core 10 and the second filter core 11 are connected to each other, so that the first filter core 10 and the second filter core 11 form a V-shaped distribution. The first filter core 10 and the second filter core 11 are slidably arranged on the frame body 9, so that the first filter core 10 and the second filter core 11 can slide out from the opening 14. The cover plate 2 can be fixed on the opening 14 with screws to seal the opening 14 and prevent air leakage. A sealing strip can also be arranged on the cover plate 2 to make the sealing effect better. When cleaning is needed, only the screws need to be removed to take off the cover plate 2, so that the opening 14 is in an open state, thus facilitating the cleaning of the impurities inside the box body 1. Moreover, the first filter core 10 and the second filter core 11 can be pulled out from the opening 14 for cleaning and directly inserted back after completion. The operation is simple and the cleaning is convenient.

[0018] Specifically, first slide rail grooves 12 and second slide rail grooves 13 are arranged on both sides of the frame body 9 in this embodiment. Both sides of the first filter core 10 are inserted into the first slide rail grooves 12 on both sides, and both sides of the second filter core 11 are inserted into the second slide rail grooves 13 on both sides. The first slide rail grooves 12 and the second slide rail grooves 13 communicate with the opening 14; thus, it is convenient to remove and install the first filter core 10 and the second filter core 11 from the opening 14, and the operation is more convenient.

[0019] It should be noted that a first conical box 3 communicating with the filtering cavity is provided on one side of the box body 1 of this embodiment, and a second conical box 4 communicating with the filtering cavity is provided on the other side. The air inlet 5 is mounted on the first conical box 3, and the air outlet 6 is mounted on the second conical box 4. Since the inner walls of the first conical box 3 and the second conical box 4 both have inclined surfaces, most of the large-particle impurities can automatically fall to the bottom of the box body 1 to facilitate cleaning.

[0020] It should also be noted that butterfly valves 7 are installed in both the air inlet 5 and the air outlet 6 of this embodiment, and pressure gauges 8 are installed in both the air inlet 5 and the air outlet 6. The air inlet volume and the air outlet volume can be controlled by the butterfly valves 7, and the pressure gauges 8 can be used to detect the pressures of the air inlet 5 and the air outlet 6 so as to facilitate judging whether the box body 1 is blocked.

[0021] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
