Description

Technical Field

[0001] This utility model relates to the field of ceramic production equipment technology, and in particular to a diesel-electric hybrid kiln for ceramic production. Background Technology

[0002] Egg-shaped kilns, used in ceramic production, resemble half an egg in shape, with a high and wide front and a low and narrow back. They are a traditional type of kiln unique to ceramic production areas like Jingdezhen. They are inexpensive to build, easy to construct, have thin walls, and are insulated with sand. The spacious kiln chamber can accommodate a large number of ceramic products for simultaneous firing, making them an indispensable firing tool in the ceramic industry. In ceramic production, the egg-shaped kiln, with its unique design and significant advantages, has become a trusted choice for many ceramic producers. To improve the kiln's heating efficiency, a new type of diesel-electric hybrid kiln has been developed by integrating modern electric firing technology with traditional kilns. This results in kilns with advantages such as rapid heating, high production efficiency, energy saving, environmental friendliness, and convenient operation, making them widely applicable in the ceramic production field.

[0003] In existing large-capacity egg-shaped diesel-electric hybrid kilns, the electric heating components are surrounded by the inner wall and bottom of the kiln. When the electric heating function is turned on, due to the large size of the kiln, the electric heating devices located on the kiln wall and bottom cannot quickly heat the air in the center of the kiln, resulting in a low electric heating rate and an inability to further improve production efficiency. Utility Model Content

[0004] This disclosure relates to a diesel-electric hybrid kiln for ceramic production, which addresses the problem in existing large-capacity egg-shaped diesel-electric hybrid kilns where the electric heating components surround the inner wall and bottom of the kiln. When the electric heating function is activated, the kiln is too large, and the electric heating devices located on the kiln wall and bottom cannot quickly heat the air in the center of the kiln, resulting in a low electric heating rate and an inability to further improve production efficiency.

[0005] In a first aspect, this disclosure provides a diesel-electric hybrid kiln for ceramic production, specifically comprising: an egg-shaped kiln, wherein an external electric heating tube is installed on the inner wall of the egg-shaped kiln, an inner kiln pad is provided at the bottom of the inner kiln, a first support plate and a second support plate are fixedly connected inside the inner kiln pad, a pad cover plate covers the upper part of the inner kiln pad, the bottom surface of the pad cover plate is in contact with the upper edges of the first support plate and the second support plate, a circulating air vent is provided above the pad cover plate, a circulating air jet seat is installed inside the circulating air vent, a floating baffle is installed above the circulating air jet seat, a baffle guide tube is fixedly connected to the bottom of the floating baffle, a guide tube through opening is provided through the wall of the baffle guide tube, and the inner kiln pad is connected to the output port of a heat-resistant blower through a pipe.

[0006] In at least some embodiments, the second support plate is perpendicular to the first support plate, and the first support plate has a support plate connecting opening. The channel formed between the two first support plates located at the center is connected to the cavity formed by the second support plates on both sides through the support plate connecting opening.

[0007] In at least some embodiments, a fan port is provided in front of the kiln inner support platform, the fan port is connected to the air supply pipe of a heat-resistant fan, and the fan port is connected to the channel formed by the two first support plates.

[0008] In at least some embodiments, an internal electric heating tube is arranged inside the kiln pad, a limiting inner ring is fixedly connected to the lower edge of the circulating air vent, and the circulating jet seat is located inside the circulating air vent.

[0009] In at least some embodiments, a sloping-bottom collecting cylinder is fixedly connected below the circulating jet seat, the sloping-bottom collecting cylinder is slidably connected to the limiting inner ring, and the bottom surface of the sloping-bottom collecting cylinder has a sloping structure.

[0010] In at least some embodiments, the bottom edge of the inclined bottom collecting cylinder is provided with an air inlet, and the upper edges of the inner left and right walls of the circulating jet seat are bent to form a limiting inner edge.

[0011] In at least some embodiments, the lower two edges of the baffle guide tube are folded outward to form a limiting outer edge, which is slidably connected inside the circulating jet seat.

[0012] This utility model provides a diesel-electric hybrid kiln for ceramic production, which has the following beneficial effects:

[0013] The diesel-electric hybrid kiln of this invention is a large-capacity egg-shaped kiln with a large internal space. When the egg-shaped kiln is heated by electric heating, the kiln walls and bottom are heated by external and internal electric heating tubes. At the same time, a heat-resistant fan is started to introduce air from inside the kiln into the kiln pad. The air is heated by the internal electric heating tubes and then enters the kiln again through the circulating air inlet and guide tube opening. It flows inside the kiln and contacts the kiln wall, heating the air inside the kiln. This improves the uniformity of temperature rise of the air inside the kiln and allows the kiln environment to quickly reach the set conditions. This avoids the situation where the electric heating elements cannot quickly heat the air in the center of the kiln due to the large size of the egg-shaped kiln.

[0014] Furthermore, through the cooperation of the circulating jet seat and the floating baffle, the floating baffle normally covers the circulating jet seat, and the baffle guide tube and guide tube opening are hidden inside the circulating jet seat. This prevents impurities and debris inside the egg-shaped kiln from falling into the kiln pad through the guide tube opening, thus avoiding blockage. When the heat-resistant blower is working, the air pressure inside the kiln pad is greater than the external air pressure. Under the action of air pressure, the floating baffle is pushed upward, so that the guide tube opening is connected to the air inside the egg-shaped kiln, allowing the air to circulate. This reduces the probability of the air circulation channel being blocked by impurities.

[0015] In addition, a sloping bottom collection cylinder is provided at the bottom of the circulating jet seat. The bottom of the sloping bottom collection cylinder has a sloping structure. If a small amount of impurities fall through the guide tube through the opening into the circulating jet seat, the impurities will slide down with the sloping bottom of the collection cylinder and accumulate inside the collection cylinder. The circulating jet seat can be extracted from the circulating air vent to clean the impurities inside the collection cylinder regularly, which facilitates the cleaning and maintenance of the kiln.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Example 1: Please refer to Figures 1 to 10 :

[0033] This utility model proposes a diesel-electric hybrid kiln for ceramic production, comprising: an egg-shaped kiln 1, with an external electric heating tube 3 installed on the inner wall of the egg-shaped kiln 1; an inner kiln platform 2 provided at the bottom of the inner kiln 1; a first support plate 201 and a second support plate 202 fixedly connected inside the inner kiln platform 2; a platform cover plate 203 covering the inner kiln platform 2, with the bottom surface of the platform cover plate 203 abutting against the upper edges of the first support plate 201 and the second support plate 202; a circulating air inlet 207 opening above the platform cover plate 203; the inner kiln platform 2 connected to the output port of a heat-resistant blower 6 via a pipe; a blower pipe inlet 204 opening at the front of the inner kiln platform 2, with the blower pipe inlet 204 inserted into the air supply pipe of the heat-resistant blower 6; and the blower pipe inlet 204 connecting to the passage formed by the two first support plates 201. The kiln inner platform 2 is equipped with an inner electric heating tube 206. The lower edge of the circulating air vent 207 is fixedly connected to a limiting inner ring 208. The circulating air jet seat 4 is located inside the circulating air vent 207. The kiln wall and bottom are heated by the outer electric heating tube 3 and the inner electric heating tube 206. At the same time, the heat-resistant fan 6 is started to input the air inside the kiln into the kiln inner platform 2. After being heated by the inner electric heating tube 206, the air passes through the circulating air vent 207 and the guide tube throughlet 502 and re-enters the kiln. It flows inside the kiln and contacts the inner wall of the kiln to heat the air inside the kiln. This can improve the temperature uniformity of the air inside the kiln and make the internal environment of the kiln reach the set conditions quickly. It is suitable for large-volume kilns.

[0034] In this embodiment, the second support plate 202 is perpendicular to the first support plate 201. The first support plate 201 has a support plate connecting opening 205. The channel formed between the two first support plates 201 located in the center is connected to the cavity formed by the second support plates 202 on both sides through the support plate connecting opening 205. The first support plate 201 and the second support plate 202 support the platform cover plate 203, thereby improving the load-bearing strength of the platform cover plate 203. During the firing of ceramics, the ceramics are placed on the platform cover plate 203.

[0035] In this embodiment, a sloping-bottom collecting cylinder 401 is fixedly connected to the lower part of the circulating jet seat 4. The sloping-bottom collecting cylinder 401 is slidably connected to the limiting inner ring 208. The bottom surface of the sloping-bottom collecting cylinder 401 has a sloping structure. The circulating jet seat 4 is installed inside the circulating air outlet 207. A floating baffle 5 is installed above the circulating jet seat 4. A baffle guide cylinder 501 is fixedly connected to the bottom of the floating baffle 5. A guide cylinder through-hole 502 is opened through the cylinder wall of the baffle guide cylinder 501. Under normal conditions, the floating baffle 5 covers the circulating jet seat 4. The baffle guide cylinder 501 and the guide cylinder through-hole 502 are hidden inside the circulating jet seat 4, so that impurities and debris inside the egg-shaped kiln 1 cannot fall into the kiln pad 2 through the guide cylinder through-hole 502, thus avoiding blockage. When the heat-resistant blower 6 is working, the air pressure inside the kiln pad 2 is greater than the external air pressure. Under the action of the air pressure, the floating baffle 5 is pushed upward, so that the guide cylinder through-hole 502 is connected to the air inside the egg-shaped kiln 1, so that the air can circulate.

[0036] In Example 2, based on Example 1, an air inlet 402 is provided on the bottom edge of the inclined bottom collecting cylinder 401. The upper edges of the left and right inner walls of the circulating jet seat 4 are bent to form a limiting inner edge 403. The two lower edges of the baffle guide cylinder 501 are bent outward to form a limiting outer edge 503. The limiting outer edge 503 is slidably connected to the inside of the circulating jet seat 4. An inclined bottom collecting cylinder 401 is provided at the bottom of the circulating jet seat 4. The bottom of the inclined bottom collecting cylinder 401 has an inclined structure. If a small amount of impurities fall through the guide cylinder throughlet 502 into the inside of the circulating jet seat 4, the impurities will slide down with the inclined bottom of the inclined bottom collecting cylinder 401 and accumulate inside the inclined bottom collecting cylinder 401. The circulating jet seat 4 can be extracted from the inside of the circulating air outlet 207 to remove the impurities inside the inclined bottom collecting cylinder 401.

[0037] The working principle of this embodiment is as follows: First, when starting the kiln by electric heating, the external heating tube 3 and the internal heating tube 206 are turned on. The external heating tube 3 and the internal heating tube 206 heat the inner wall and bottom of the kiln respectively. At the same time, the heat-resistant fan 6 is turned on, and the heat-resistant fan 6 delivers the air inside the kiln to the kiln pad 2, which increases the air pressure inside the kiln pad 2. Under the action of air pressure, the floating baffle 5 is pushed upward, so that the guide tube through-hole 502 is connected to the internal space of the kiln. The air inside the kiln pad 2 flows outward through the guide tube through-hole 502, so that the flowing air comes into contact with the external heating tube 3 and the internal heating tube 206 and flows and mixes inside the kiln, so that the air inside the kiln quickly reaches the set temperature. After the kiln is used once, the circulating jet seat 4 is pulled out from the circulating air port 207 inside the kiln, and the impurities inside the inclined bottom collection cylinder 401 are poured out through the air outlet 402 to achieve rapid cleaning of the egg-shaped kiln.
