Description

Technical Field

[0001] This application belongs to the field of calcination processing technology, specifically an energy-saving calcination device. Background Technology

[0002] With the development and progress of the gypsum industry, the demand for gypsum powder is increasing, and the quality requirements for gypsum powder are also becoming higher. The production and manufacturing process of gypsum powder is also constantly improving. Dehydration is a key step in the production and processing of gypsum powder. However, there are still some problems in the use of calcination equipment for gypsum dehydration. At present, general gypsum calcination equipment will leave a lot of waste heat during calcination. This waste heat cannot be effectively utilized, resulting in energy waste. In addition, the exhaust gas emissions of existing calcination equipment also cause significant environmental pollution. Therefore, targeted design improvements are needed.

[0003] For example, CN215712668U discloses an energy-saving and environmentally friendly gypsum calcination processing device, including a calcination box. A burner is installed on the upper side of the calcination box, and a feed inlet is installed on the right side of the calcination box. A diverter block is installed at the bottom of a water tank at the top of the calcination box. The top of the water tank is connected to a water tank via an exhaust pipe, and the top of the water tank has an exhaust port connected to the exhaust pipe via a connecting pipe. This invention, by incorporating a fan, exhaust pipe, water tank, water tank, and connecting pipe, first purifies the calcination gas while simultaneously heating the water in the water tank, thus placing the entire calcination box in a high-temperature environment. This allows for preheating of the gypsum before calcination, reducing calcination time. Then, the water in the water tank is heated via the connecting pipe, and the hot water in the tank can be used for domestic purposes. Therefore, the calcination waste gas can be utilized to the maximum extent, reducing calcination energy consumption and achieving environmental protection goals.

[0004] However, in this application, the gypsum calcination processing device generates ash and slag during the calcination process, which will lead to the accumulation of ash and slag. Utility Model Content

[0005] The purpose of this application is to provide an energy-saving calcination device to solve the aforementioned problem of ash and slag treatment.

[0006] The technical solution adopted in this application is as follows: An energy-saving calcination device includes a base plate, a calcination box is fixedly connected to the upper surface of the base plate by a support column, and an ash collection channel is connected to the bottom end of the calcination box. A filter screen is connected to one end of the ash collection channel inside the calcination box. An ash collection box is provided below the ash collection channel. A slider and a groove are provided at the connection between the ash collection box and the base plate. A handle is fixedly provided on one side surface of the ash collection box, and the groove and the slider are movably connected.

[0007] By adopting the above technical solution, the ash and slag can be effectively collected by setting up an ash and slag collection structure at the bottom of the calcination box. At the same time, it can prevent the calcination from being affected by excessive ash and slag accumulation inside the calcination box. When the calcined material on the surface of the filter screen works in conjunction with the flipping structure component, it can cause the ash and slag to fall into the ash and slag collection channel below the filter screen, and then fall into the ash and slag collection box. The operator can then pull out the ash and slag collection box by holding the handle and using the slide and slider, and then centrally process the ash and slag.

[0008] In a preferred embodiment, a water tank is fixedly connected to the upper surface of the base plate by a support column. A connecting bend is provided inside the water tank. An air outlet is connected to the top of the connecting bend, and the other end of the connecting bend is connected to a water tank inside the calcination box.

[0009] By adopting the above technical solution, the support columns set on the bottom plate surface facilitate the installation and fixation of the water tank, and can play an auxiliary role in conjunction with the internal connecting bend and the external air outlet.

[0010] In a preferred embodiment, a diversion block is provided inside the water tank, and an exhaust pipe is connected to the surface of the diversion block. The other end of the exhaust pipe is connected to a fan inside the calcining box.

[0011] By adopting the above technical solution, the fan, in conjunction with the exhaust pipe and the diversion block, can transport the flue gas generated by calcination to the interior of the water tank and the diversion block, thereby heating the water inside. At the same time, the filter screen installed at the pipe can prevent impurities in the flue gas from causing blockage.

[0012] In a preferred embodiment, a calcining nozzle is provided below the fan, and connecting plates are connected to both ends of the calcining nozzle, with both ends of the connecting plates connected to the inner wall of the base plate.

[0013] By adopting the above technical solution, the connecting plate facilitates the fixed installation of the calcining nozzle, thereby facilitating the calcining of the object by the calcining nozzle.

[0014] In a preferred embodiment, a feed inlet is connected to one side surface of the calcining box.

[0015] By adopting the above technical solution, the materials that need to be calcined can be transported into the interior of the calcination chamber through the feed inlet.

[0016] In a preferred embodiment, a door is movably provided on one outer surface of the calcining chamber, and a door handle is fixedly provided at the edge of the door surface.

[0017] By adopting the above technical solution, the door handle provided on the surface of the door facilitates the opening of the structure.

[0018] In a preferred embodiment, a fixing post is fixedly provided at the edge of the upper surface of the base plate, a flipping motor is provided on the surface of the fixing post, the output end of the flipping motor is connected to a rotating shaft inside the calcining box, and multiple flip plates are provided on the surface of the rotating shaft.

[0019] By adopting the above technical solution, the starting flipping motor can drive the flip plate to rotate through the rotating shaft, thereby flipping the objects inside the calcining box so that they can be calcined evenly. At the same time, the fixed column can fix the flipping motor.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, by setting an ash collection structure at the bottom of the calcination box, the ash can be collected effectively, and the accumulation of too much ash inside the calcination box can be prevented from affecting the calcination. When the calcined material on the surface of the filter screen works in conjunction with the flipping structure component, it can cause the ash to fall into the ash collection channel below the filter screen, and then into the ash collection box. The operator can pull out the ash collection box by holding the handle and using the slide and slider, and then centrally process the ash. Attached Figure Description
