Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramsite sand production technology, specifically to an electric heating blast drying oven based on ceramsite sand production. Background Technology
[0002] Ceramsite sand is a type of ceramic particle product with high fracturing strength. It is mainly used for downhole support in oil fields to increase the production of oil and natural gas and is an environmentally friendly product. This product is made from high-quality bauxite, coal and other raw materials through ceramic sintering. It is a substitute for medium and low strength proppants such as natural quartz sand, glass balls and metal balls, and has a good effect on increasing the production of oil and natural gas.
[0003] The traditional process for preparing ceramsite sand involves directly calcining it in a kiln after granulation. Since the granulated ceramsite sand is calcined directly without preheating, the high temperature inside the kiln (approximately 1300-1500℃) can cause cracks or even breakage of the ceramsite sand, significantly increasing the breakage rate. Furthermore, because the moisture content is high after the granules are formed, directly calcining the ceramsite sand in the kiln will affect the production efficiency of the kiln to some extent. Therefore, preheating and drying are necessary before calcination.
[0004] A search revealed that CN210689137U discloses a drying device for semi-finished ceramsite sand. This device adds semi-finished ceramsite sand from a feed hopper into a drying chamber. A diversion device is installed between the feed inlet and the drying zone of the drying chamber to divert and disperse the semi-finished product entering the drying chamber, dividing it into multiple portions. The dispersed semi-finished product is then dried, allowing for thorough heat exchange with the heat source, resulting in good drying performance. The dried semi-finished product falls through a guiding device to the feed inlet of a conveying auger. However, the applicant found that this technical solution has two drawbacks: firstly, the diversion branch pipes are prone to blockage, leading to poor diversion performance; secondly, although the ceramsite sand is dispersed, its position remains fixed during drying, resulting in clumping and insufficient or uneven drying. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an electric heating forced-air drying oven based on ceramsite sand production, which solves the problems existing in the above-mentioned prior art.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an electric heating blower drying oven based on ceramsite sand production, comprising a box body and a fixed cylinder, wherein hot air blowers are evenly arranged at the bottom of the box body, and through holes are evenly arranged on the fixed cylinder, wherein mounting boxes and discharge pipes are respectively arranged on both sides of the fixed cylinder, wherein a feed pipe is arranged on the mounting box, a connecting plate is arranged on the feed pipe, and a reduction motor is arranged on the connecting plate, wherein the output shaft of the reduction motor is connected to the mounting box through a bearing, and the right end of the output shaft of the reduction motor is connected to a rotating pipe, wherein rotating plates are evenly arranged on the outer wall of the rotating pipe and fit against the inner wall of the fixed cylinder, and a through groove first matching the discharge pipe and a through groove second matching the output shaft of the reduction motor are arranged on the box body;
[0007] An intermittent tilting component is provided on the fixed cylinder.
[0008] Preferably, the rotating tube is provided with through holes two evenly, and the rotating plate is provided with through holes three evenly, and the diameters of through holes one, two and three are all smaller than the minimum diameter of the ceramsite sand.
[0009] Preferably, the intermittent tilting assembly includes two rotating rods, both of which are connected to the housing via bearings. The housing is equipped with a rotary motor connected to the front rotating rod. Both ends of the two rotating rods are provided with round rods. The round rods on the left and right sides are respectively connected to the mounting box and the discharge pipe. The inner walls on both sides of the housing are provided with guide plates that fit and connect with the round rods.
[0010] Preferably, the top of the box is provided with a support leg, and the top of the support leg is provided with a storage box with a valve, the bottom of the storage box being opposite to the feed pipe.
[0011] Preferably, an anti-blocking rod is vertically slidably connected to the storage bin, and a movable rod hinged to the anti-blocking rod is connected to the connecting plate.
[0012] Preferably, the housing is equipped with a dehumidification component, a temperature and humidity sensor, a controller, and a through-slot that matches the feed pipe.
[0013] This invention provides an electrically heated forced-air drying oven based on ceramsite sand production. Compared with the prior art, it has the following advantages:
[0014] 1. This electric heating drying oven based on ceramsite sand production uses ceramsite sand that falls into the mounting box through the feed pipe. Under the action of the intermittent tilting component, the mounting box, the fixed cylinder, and the discharge pipe can all be tilted intermittently. This allows the ceramsite sand in the fixed cylinder to remain in the fixed cylinder for a longer period of time, so as to facilitate thorough drying and also to complete the discharge work. In addition, the geared motor drives the rotating tube and rotating plate to rotate, so that the ceramsite sand entering the fixed cylinder can be evenly distributed in the fixed cylinder. It can also rotate with the movement to the right, so not only can the material be evenly distributed, but the ceramsite sand can also keep rotating during drying to avoid accumulating, which is conducive to thorough and uniform drying.
[0015] 2. This electric heating drying oven based on ceramsite sand production can be intermittently and without manual feeding by setting up a storage box with a valve. This avoids the situation where too much ceramsite sand is added to the installation box due to excessive feeding, thereby increasing the load on the intermittent tilting component. When the intermittent tilting component is working, the connecting plate drives the movable rod to move, which can drive the anti-blocking rod to rise and fall, which is beneficial for feeding when the valve is opened.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] See Figures 1-4 This utility model provides the following two technical solutions:
[0023] First implementation: An electric heating drying oven based on ceramsite sand production includes a box body 1 and a fixed cylinder 7. Hot air blowers 2 are evenly arranged at the bottom of the box body 1, and the exhaust pipe of the hot air blowers 2 is connected to the box body 1. Through holes 6 are evenly arranged on the fixed cylinder 7 so that hot air can enter and exit through the through holes 6. Mounting boxes 8 and discharge pipes 9 are respectively arranged on both sides of the fixed cylinder 7. A feed pipe 10 is arranged on the mounting box 8. A connecting plate 11 is arranged on the feed pipe 10. A reduction motor 12 is arranged on the connecting plate 11. The output shaft of the reduction motor 12 is connected to the mounting box 8 through a bearing, and the right end of the output shaft of the reduction motor 12 is connected to a rotating pipe 13, which can drive the rotating pipe 13 to rotate. A rotating plate 14 is evenly arranged on the outer wall of the rotating pipe 13 and is attached to the inner wall of the fixed cylinder 7. In order not to affect the tilting of the discharge pipe 9 and the reduction motor 12, a through groove 22 matching the discharge pipe 9 and a through groove 23 matching the output shaft of the reduction motor 12 are arranged on the box body 1.
[0024] The fixed cylinder 7 is equipped with an intermittent tilting component, which is used to drive the fixed cylinder 7 to tilt intermittently.
[0025] The rotating pipe 13 is evenly provided with through holes 2 15, and the rotating plate 14 is evenly provided with through holes 3 16. The diameters of through holes 1 6, through holes 2 15 and through holes 3 16 are all smaller than the minimum diameter of the ceramsite sand, so that hot air can enter and exit through through holes 2 15 and through holes 3 16, and thus the ceramsite sand at different positions can be dried when the rotating plate 14 drives the ceramsite sand to rotate.
[0026] The intermittent tilting assembly includes two rotating rods 18, both of which are connected to the housing 1 via bearings. A rotary motor 19 connected to the front rotating rod 18 is installed on the housing 1. Both ends of the two rotating rods 18 are provided with round rods 20. The round rods 20 on the left and right sides are respectively connected to the mounting box 8 and the discharge pipe 9. In order to improve the stability of the rotation of the fixed cylinder 7, guide plates 21 that fit and connect with the round rods 20 are provided on the inner walls of both sides of the housing 1.
[0027] Manually feeding the material intermittently is too laborious. If all the ceramsite sand is added into the installation box 8 manually at once, the load on the rotary motor 19 will be too large when the fixed cylinder 7 rotates and tilts. Therefore, a support leg is provided on the top of the box 1, and a storage box 24 with a valve 25 is provided on the top of the support leg. The bottom of the storage box 24 is opposite to the feed pipe 10. After the ceramsite sand is added into the storage box 24, the valve 25 can be opened intermittently to realize the function of intermittent feeding into the feed pipe 10.
[0028] An anti-blocking rod 26 is vertically slidably connected to the storage box 24, and a movable rod 27 hinged to the connecting plate 11 is hinged to the anti-blocking rod 26. When the connecting plate 11 rotates and tilts, the movable rod 27 can drive the anti-blocking rod 26 to move up and down repeatedly. Then, when the valve 25 is opened, the anti-blocking rod 26 moves up and down to agitate the ceramsite sand, which is beneficial for material discharge.
[0029] The second implementation method differs from the first implementation method in that: the housing 1 is equipped with a dehumidification component 3, a temperature and humidity sensor 4, a controller 5, and a through groove 3 that matches the feed pipe 10. The temperature and humidity sensor 4 detects the temperature and humidity inside the housing 1. When the temperature is too high, the controller 5 controls the hot air blower 2 to lower the temperature. When the humidity is too high, the dehumidification component 3 is turned on or the dehumidification intensity is increased. When the feed pipe 10 is tilted, it can be tilted in the through groove 3.
[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0031] In use, ceramsite sand is intermittently fed into the feed pipe 10, while the reduction motor 12 and the rotary motor 19 are turned on. The rotary motor 19 drives the fixed cylinder 7 to tilt to the lower right and then return to its horizontal position, thus allowing the fixed cylinder 7 to tilt intermittently. When tilted, the ceramsite sand falling into the mounting box 8 can enter the fixed cylinder 7 and move along the fixed cylinder 7. The rotating pipe 13 drives the rotating plate 14 to rotate, so that the ceramsite sand entering the fixed cylinder 7 can be evenly distributed between adjacent rotating plates 14, so that it can be evenly contacted with the hot air sent by the hot air blower 2 below. The intermittent tilting does not affect the rightward movement of the ceramsite sand and also prolongs the time the ceramsite sand stays in the fixed cylinder 7, so that when the rotating plate 14 drives the ceramsite sand to rotate, it can be dried more evenly and fully. The preheated and dried ceramsite sand is finally discharged through the discharge pipe 9.
