Abstract
Description
Technical Field
[0001] This utility model relates to the field of kiln accessories technology, specifically a ventilation structure for an electric porcelain firing kiln. Background Technology
[0002] As a key piece of equipment in the production of electrical porcelain products, the rationality and efficiency of the ventilation structure of the firing kiln directly affect the firing quality and production efficiency. A good ventilation structure not only ensures uniform temperature distribution inside the kiln but also effectively removes harmful gases and excess heat generated during firing, thereby guaranteeing the firing quality of electrical porcelain products and the operational stability of the kiln. Some kilns have unreasonable ventilation structure designs, resulting in poor air circulation and low ventilation efficiency. This not only affects the temperature uniformity inside the kiln but may also cause localized overheating or uneven heating, thus affecting the firing quality of electrical porcelain products. Some kilns have complex ventilation structures with numerous components that are difficult to disassemble. This makes cleaning and maintenance of the ventilation structure during kiln maintenance extremely cumbersome, increasing maintenance costs and time. Utility Model Content
[0003] The purpose of this utility model is to provide a ventilation structure for an electric porcelain firing kiln to solve the problems of insufficient ventilation efficiency and inconvenient maintenance of existing kilns mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A ventilation structure for an electric porcelain firing kiln includes a blower box for the electric porcelain firing kiln. The blower box is in the shape of a hollow inverted regular square truncated pyramid. A ventilation mesh plate is installed on the top of the blower box. An air duct for blowing air is vertically connected to one side of the outer wall of the blower box. A movable pull-out plate is installed at the bottom of the blower box.
[0006] The top of the blower box is equipped with a square ring-shaped top seat. The inner wall edge of the top seat is provided with an inner ring groove for fixing the ventilation mesh plate. The bottom opening of the blower box is symmetrically provided with L-shaped fixed slides on both sides. The height of the slide groove of the fixed slide is the same as the thickness of the movable pull-out plate.
[0007] The surface of the ventilation mesh plate has several sets of ventilation holes arranged evenly and at equal intervals.
[0008] Preferably, a limiting pin for locking the ventilation mesh plate is installed on the outer wall of the top seat, and a through hole that matches the size of the limiting pin and is inserted into the outer wall of the ventilation mesh plate.
[0009] Preferably, the cross-sectional area of the inner ring groove is the same as the cross-sectional area of the ventilation mesh plate, and the two are interlocked.
[0010] Preferably, a blower is installed at the end of the duct away from the blower box, and the outlet pipe of the blower is interference-fitted with the end of the duct.
[0011] Preferably, a pull rod is installed on the middle of the outer wall of one end of the movable pull-out plate.
[0012] Preferably, a pull ring is installed at the end of the pull rod away from the movable pull plate.
[0013] Preferably, the blower box, top seat, ventilation mesh plate and movable pull-out plate are all made of steel plate with a thickness of 5-15mm.
[0014] Compared with existing technologies, the beneficial effects of this utility model are:
[0015] 1. In the ventilation structure of this electric porcelain firing kiln, a hollow, inverted square truncated pyramid-shaped blower box is set up to effectively guide airflow. Combined with the air duct, it provides sufficient ventilation for the kiln. The ventilation mesh plate installed on the top and the ventilation holes evenly spaced on its surface can perform preliminary filtration of the air entering the kiln and ensure uniform ventilation. The top seat and its inner ring groove facilitate the fixing of the ventilation mesh plate, making installation and maintenance convenient. The fixed sliding seats with L-shaped cross sections symmetrically set on both sides of the bottom opening, in conjunction with the movable pull-out plate, make it convenient to clean the impurities inside the blower box. The cleaning work can be carried out by simply pulling out the movable pull-out plate.
[0016] 2. In the ventilation structure of this electric porcelain firing kiln, a limiting pin for locking the ventilation mesh plate is installed on the outer wall of the top seat. The outer wall of the ventilation mesh plate has through holes that are compatible with the size of the limiting pin and can be inserted into it, so that the ventilation mesh plate can be firmly locked after installation, preventing the ventilation mesh plate from loosening or shifting due to airflow impact and other factors during the operation of the kiln, thus ensuring the stability and safety of ventilation.
[0017] 3. In the ventilation structure of this electric porcelain firing kiln, a pull rod is installed in the middle of the outer wall of one end of the movable pull plate, and a pull ring is installed at the end of the pull rod away from the movable pull plate. This allows the operator to easily pull the pull rod through the pull ring and thus easily pull the movable pull plate out from the bottom of the blower box, greatly facilitating the cleaning and maintenance of the inside of the blower box.

[0029] A ventilation structure for an electric porcelain firing kiln, such as Figures 1-3As shown, the device includes a blower box 10 for firing electric porcelain kilns. The blower box 10 is a hollow, inverted regular square truncated pyramid. A ventilation mesh plate 20 is installed on the top of the blower box 10. An air duct 30 for blowing air is vertically connected to one outer wall of the blower box 10. A movable pull-out plate 40 is installed at the bottom of the blower box 10. A square ring-shaped top seat 11 is installed on the top of the blower box 10. An inner ring groove 12 for fixing the ventilation mesh plate 20 is opened on the inner edge of the inner wall of the top seat 11. Fixed slides 13 with L-shaped cross sections are symmetrically arranged on both sides of the bottom opening of the blower box 10. The height of the groove of the fixed slide 13 is the same as the thickness of the movable pull-out plate 40. The surface of the ventilation mesh plate 20 is opened with... Several sets of evenly spaced ventilation holes 21 are provided. By setting a blower box 10 in the shape of a hollow inverted square truncated pyramid, airflow can be effectively guided. In conjunction with the air duct 30, air is blown in to provide sufficient ventilation for the kiln. The ventilation mesh plate 20 installed on the top and the evenly spaced ventilation holes 21 on its surface can perform preliminary filtration of the air entering the kiln and ensure uniform ventilation. The top seat 11 and its inner ring groove 12 facilitate the fixing of the ventilation mesh plate 20, making installation and maintenance convenient. The fixed slide seats 13 with L-shaped cross sections are symmetrically arranged on both sides of the bottom opening. They cooperate with the movable pull plate 40 to make it convenient to clean the impurities inside the blower box 10. The cleaning work can be carried out by pulling out the movable pull plate 40.
[0030] Furthermore, a limiting pin 14 for locking the ventilation mesh plate 20 is installed on the outer wall of the top seat 11. The outer wall of the ventilation mesh plate 20 is provided with a through hole that matches the size of the limiting pin 14 and is inserted into it, so that the ventilation mesh plate 20 can be firmly locked after installation, preventing the ventilation mesh plate 20 from loosening or shifting due to airflow impact and other factors during the operation of the kiln, and ensuring the stability and safety of ventilation.
[0031] It is worth noting that the cross-sectional area of the inner ring groove 12 is the same as that of the ventilation mesh plate 20, and the two are interlocked, which facilitates the precise installation and positioning of the ventilation mesh plate 20.
[0032] Specifically, a blower 50 is installed at the end of the duct 30 away from the blower box 10. The air outlet of the blower 50 is interference-fitted with the end of the duct 30, which enables the generation of sufficient wind force to stably blow air into the blower box 10 through the duct 30, thereby meeting the ventilation requirements of the electric porcelain firing kiln and ensuring a stable firing environment inside the kiln.
[0033] The movable pull plate 40 has a pull rod 41 installed in the middle of the outer wall of one end. The end of the pull rod 41 away from the movable pull plate 40 has a pull ring 42 installed, which makes it easy for the operator to pull the pull rod 41 through the pull ring 42, thereby easily pulling the movable pull plate 40 out from the bottom of the blower box 10, which greatly facilitates the cleaning and maintenance of the inside of the blower box 10.
[0034] In addition, the blower box 10, top seat 11, ventilation mesh plate 20 and movable pull-out plate 40 are all made of steel plates with a thickness of 5-15mm, which ensures that each component has sufficient strength and durability, can withstand the high temperature environment during kiln operation and frequent air flow impact, extend the overall service life of the ventilation structure and reduce maintenance costs.
[0035] The working principle of the ventilation structure of this electric porcelain firing kiln:
[0036] When using the ventilation structure of the electric porcelain firing kiln, first turn on the blower 50 installed at the end of the air duct 30 away from the blower box 10. The air generated by the blower 50 is blown into the blower box 10, which is a hollow inverted square truncated pyramid shape, through the air duct 30 that is interference-fitted with it. The blower box 10 guides the airflow, and the air passes through the ventilation mesh plate 20 installed in the inner ring groove 12 of the top seat 11. The ventilation holes 21 evenly spaced on the surface of the ventilation mesh plate 20 perform preliminary filtration of the air before entering the kiln, providing sufficient and clean air for the firing process.
[0037] If it is necessary to clean the inside of the blower box 10, the operator can pull the pull ring 42 on the pull rod 41 connected to the middle of the outer wall of one end of the movable pull plate 40 to pull the movable pull plate 40 out from the fixed slides 13 on both sides of the bottom of the blower box 10. After cleaning, the movable pull plate 40 can be pushed back to its original position.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
