Description

Technical Field

[0001] This utility model specifically relates to a drying device for refractory brick production, belonging to the field of refractory brick production technology. Background Technology

[0002] Refractory materials are generally divided into two types: unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also known as castables, are mixed powdery granules composed of various aggregates and one or more binders. They must be mixed with one or more liquids and stirred evenly before use. They have strong fluidity. Shaped refractory materials generally refer to refractory bricks, which have standard and regular shapes, but can also be temporarily processed during construction as needed.

[0003] A patent with publication number CN210061539U discloses a drying device for refractory bricks. This technology discloses a technical solution that includes "a base plate, two vertical plates fixedly connected to the upper surface of the base plate, rotating rods rotatably connected to the opposite sides of the two vertical plates via bearings, and support plates fixedly connected to the opposite ends of the two rotating rods, etc., which has the technical effects of drying both sides of refractory bricks, uniformly drying stacked refractory bricks, and fast drying speed."

[0004] However, in this prior art, it is not convenient to take out the dried refractory bricks. At the same time, during the drying process, since there is no protective plate, the refractory bricks are easily displaced during rotation by squeezing from above, or even fly out of the drying area, causing safety hazards. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a drying device for refractory brick production.

[0006] The present invention achieves the above objectives through the following technical solution: a drying device for refractory brick production, comprising a drying table and a heating plate disposed on the surface of the drying table, wherein upright plates are fixedly connected to both sides of the drying table, and a placement assembly disposed above the heating plate.

[0007] The placement assembly includes a placement plate disposed above the heating plate. Connecting plates are fixedly connected to both sides of the placement plate. A rotating rod is fixedly connected to the side of the connecting plate away from the placement plate. Both rotating rods are rotatably connected to the upright plate, and one of the rotating rods passes through the upright plate and is connected to a motor mounted on the surface of the upright plate.

[0008] By adopting the above technical solution, the drying device for refractory brick production mainly consists of a drying table, a heating plate, a vertical plate, and a placement assembly. The placement plate in the placement assembly is used to support the refractory bricks and is located above the heating plate. The connecting plate is fixed on both sides of the placement plate and is used to connect the rotating rod. The rotating rod is rotatably connected to the vertical plate. One of the rotating rods passes through the vertical plate and is connected to a motor. The motor drives the rotating rod to rotate, which in turn drives the placement plate to rotate, so that the refractory bricks are heated evenly during the drying process.

[0009] Preferably, the surface of the placement plate is fixedly connected with a plurality of protrusions.

[0010] By adopting the above technical solution, the protrusions prevent the refractory bricks from sliding when the placement plate rotates, ensuring stability during the drying process. At the same time, the protrusions can support the refractory bricks, preventing them from sticking to the placement plate over a large area, which is conducive to heat conduction at the bottom.

[0011] Preferably, the surface of the placement plate has a plurality of circular holes.

[0012] By adopting the above technical solution, the hot air generated by the heating plate can flow upward through the round hole, passing through the bottom of the refractory brick, accelerating the evaporation of moisture, and further improving the drying effect.

[0013] Preferably, each of the upright plates has two auxiliary rods hinged to its surface. The end of each auxiliary rod is slidably connected to a first fixed post through a groove. The surface of the connecting plate is provided with a fixing hole that matches the first fixed post. Each auxiliary rod has a first guide post in its groove. The surface of the first guide post is wound with a first spring. The first guide post is slidably connected to the first fixed post. The two ends of the first spring are fixedly connected to the first fixed post and the auxiliary rod, respectively.

[0014] By adopting the above technical solution, an auxiliary rod is hinged to the surface of the upright plate. The end of the auxiliary rod is connected to the first fixed column through a sliding groove. The surface of the connecting plate is provided with a fixing hole adapted to the first fixed column. A first guide column and a first spring are set in the sliding groove. The two ends of the spring are connected to the fixed column and the auxiliary rod respectively. The auxiliary rod can rotate around the hinge point of the upright plate to adjust the angle. When the refractory bricks need to be removed after drying, the auxiliary rod can be aligned with the fixing hole. At this time, the first spring pushes the first fixed column to insert into the fixing hole of the connecting plate to lock the position of the placement plate. The guide column ensures that the fixed column slides smoothly and prevents displacement. With this method, it is convenient for workers to remove the refractory bricks.

[0015] Preferably, it also includes a reinforcement component disposed above the placement plate;

[0016] The reinforcement assembly includes a hinge rod disposed above the placement plate. Two pressure plates are hinged to the surface of the hinge rod. Each of the two connecting plates has a moving groove on an adjacent side. A lead screw and a guide rod are respectively disposed on the inner side of the two moving grooves. A slider is disposed on the surface of the lead screw and the guide rod. The two sliders are fixedly connected to the hinge rod. A knob is fixedly connected to the upper end of the lead screw.

[0017] By adopting the above technical solution, the reinforcement component includes a hinge rod, a lower pressure plate, a lead screw, a guide rod, a slider, and a knob. The lead screw and guide rod are set in the moving groove of the connecting plate. The slider is fixedly connected to the hinge rod. The knob drives the lead screw to rotate. By rotating the knob, the lead screw rotates, and the slider moves up and down along the lead screw and guide rod. The movement of the slider drives the lower pressure plate to rise and fall through the hinge rod, pressing down the refractory brick and fixing it on the placement plate. By adjusting the lower pressure plate, it can accommodate refractory bricks of different thicknesses and improve drying stability (limiting blocks are set on the surface of the hinge rod, so that the lower pressure plate can only be flipped upward).

[0018] Preferably, each of the two lower pressure plates is provided with a folding positioning block and a spring pin, and the folding positioning block and the spring pin correspond one-to-one. The lower pressure plate has a positioning groove adapted to the folding positioning block at the end of the spring pin, and the surface of the folding positioning block has a round hole adapted to the spring pin.

[0019] By adopting the above technical solution, a folding positioning block and a spring pin are set on the surface of the lower pressure plate, and the two correspond one to one. The positioning groove and the round hole are respectively opened on the lower pressure plate and the folding positioning block for mutual locking. The folding positioning block can be flipped into the positioning groove, and the spring pin is inserted into the round hole of the folding positioning block to fix its position. The spring pin is kept in the inserted state by elastic force to ensure the stability of the positioning block. When the lower pressure plate is not needed, the positioning block can be folded and locked to prevent the lower pressure plate from interfering with the handling or placement of refractory bricks.

[0020] Preferably, the lower pressure plate is slidably connected to the second fixed post via a sliding groove, and the surface of the connecting plate is provided with a guide groove adapted to the second fixed post. A limiting post is fixedly connected to the inner side wall of the sliding groove of the lower pressure plate. The limiting post is slidably connected to the second fixed post, and a second spring is wound around the surface of the limiting post. The two ends of the second spring are respectively fixed to the lower pressure plate and the second fixed post.

[0021] By adopting the above technical solution, the lower pressure plate is slidably connected to the second fixed column through the slide groove. The connecting plate has a guide groove, and a limiting column and a second spring are set in the slide groove. The spring connects the lower pressure plate and the second fixed column. The second fixed column can slide along the slide groove and insert into the guide groove of the connecting plate to fix the position of the lower pressure plate. Through the cooperation of the second fixed column and the guide groove, the fixing effect of the lower pressure plate is further enhanced, and at the same time, it provides guidance for the movement trajectory of the two lower pressure plates.

[0022] Preferably, protective frames are installed on both sides of the lower pressure plate, and a number of locking posts are fixedly connected to the inner side of the protective frame. The surface of the placement plate is equipped with locking blocks that are compatible with the locking posts on the surface of the protective frame.

[0023] By adopting the above technical solution, protective frames are installed on both sides of the lower pressure plate, and clamping posts are set on the inner side. Clamping blocks that are compatible with the clamping posts are installed on the surface of the placement plate. The protective frames are connected to the clamping posts and clamping blocks to form a fence structure, which restricts the lateral movement of refractory bricks on the placement plate. At the same time, the cooperation between the clamping posts and clamping blocks allows for the quick installation or removal of the protective frames, adapting to the drying needs of refractory bricks of different sizes.

[0024] The beneficial effects of this utility model are: In the drying process, the protrusions on the surface of the placement plate can reduce the contact area between the refractory brick and the plate, forming an air circulation gap, accelerating heat conduction and moisture discharge. At the same time, the round holes on the placement plate further enhance air convection, allowing the heat from the heating plate to act more directly on the refractory brick, while facilitating the discharge of moisture from the bottom and shortening the drying time.

[0025] When it is necessary to pick up or place refractory bricks, the auxiliary rod is inserted into the fixing hole of the connecting plate through the first fixing post, locking the placement plate to prevent it from rotating, thus facilitating the placement or picking up of refractory bricks.

[0026] The height of the lower pressure plate can be adjusted by the screw knob to accommodate refractory bricks of different thicknesses and achieve flexible clamping. The folding positioning block and the spring pin form a double locking structure. When drying or placing refractory bricks, the folding positioning block is inserted into the positioning groove and fixed by the spring pin to prevent the lower pressure plate from loosening, thus facilitating the operation of the staff.

[0027] The protective frames on both sides of the lower pressure plate cooperate with the locking blocks of the placement plate through the locking posts to prevent refractory bricks from falling during rotation or drying, thus playing a safety protection role. At the same time, they help to position the bricks and prevent misalignment when stacking. Attached Figure Description

A rotating rod 22 is fixedly connected to the side of the connecting plate 23 away from the placement plate 24. Both rotating rods 22 are rotatably connected to the upright plate 12, and one of the rotating rods 22 passes through the upright plate 12 and is connected to a motor 21 mounted on the surface of the upright plate 12.

A first spring 272 is wound around the surface of the first guide post 273. The first guide post 273 is slidably connected to the first fixing post 271. The two ends of the first spring 272 are fixedly connected to the first fixing post 271 and the auxiliary rod 26, respectively.

[0044] It also includes a reinforcing component 3 disposed above the placement plate 24;

[0045] The reinforcement component 3 includes a hinge rod 35 disposed above the placement plate 24. Two pressure plates 36 are hinged to the surface of the hinge rod 35. Each of the two adjacent sides of the two connecting plates 23 is provided with a moving groove. A lead screw 31 and a guide rod 34 are respectively disposed inside the two moving grooves. A slider 32 is disposed on the surface of the lead screw 31 and the guide rod 34. The two sliders 32 are fixedly connected to the hinge rod 35. A knob 33 is fixedly connected to the upper end of the lead screw 31.

[0046] Both lower pressure plates 36 are provided with folding positioning blocks 311 and spring pins 312 on their surfaces, and the folding positioning blocks 311 and spring pins 312 correspond one to one. The lower pressure plate 36 is provided with a positioning groove at the end of the spring pin 312 that is adapted to the folding positioning block 311, and the surface of the folding positioning block 311 is provided with a round hole that is adapted to the spring pin 312.

[0047] The lower pressure plate 36 is slidably connected to the second fixed post 37 via a sliding groove, and the surface of the connecting plate 23 is provided with a guide groove 310 that is adapted to the second fixed post 37. The inner side wall of the sliding groove of the lower pressure plate 36 is fixedly connected to a limiting post 39, which is slidably connected to the second fixed post 37. The surface of the limiting post 39 is wound with a second spring 38, and the two ends of the second spring 38 are fixed to the lower pressure plate 36 and the second fixed post 37 respectively.

[0048] Both sides of the lower pressure plate 36 are equipped with protective frames 313. Several locking posts are fixedly connected to the inner side of the protective frame 313. The surface of the placement plate 24 is equipped with locking blocks 314 that are compatible with the locking posts on the surface of the protective frame 313.

[0049] Working principle: When it is necessary to dry refractory bricks, the refractory bricks can be placed on the placement plate 24. The protrusions 25 on the surface can increase the friction and prevent the refractory bricks from sliding. At the same time, the gap between the protrusions 25 can promote heat flow. By starting the motor 21, the output shaft of the motor 21 drives the rotating rod 22 to rotate, thereby causing the placement plate 24 to rotate around the vertical plate 12. The refractory bricks rotate with the placement plate 24 to ensure that all surfaces of the bricks are evenly exposed to the heat of the heating plate 11, avoiding local overheating or uneven drying. When drying is complete, the auxiliary rod 26 unfolds through the hinge point, and the first fixing post 271 at the end pops out under the action of the first spring 272 and inserts into the fixing hole 27 of the connecting plate 23, locking the position of the placement plate 24 and preventing the placement plate 24 from rotating when the refractory bricks are taken out. During this process, the first spring 272 provides a restoring force, and the first guide post 273 ensures that the first fixing post 271 slides smoothly and avoids jamming. Before drying, the knob 33 can be rotated, which drives the lead screw 31 to rotate. The slider 32 on the lead screw 31 moves up and down along the guide rod 34, thereby pushing the hinge rod 35 to swing. The hinge rod 35 drives the lower pressure plate 36 to move downwards until the lower pressure plate 36 is in contact with the surface of the refractory brick, achieving initial compression. Under the action of the second spring 38, the second fixing post 37 on the lower pressure plate 36 is inserted into the guide groove 310 of the connecting plate 23 to further fix the position of the lower pressure plate 36, increase the pressure on the refractory brick, and ensure its stability during the drying process. At the same time, the protective frame 313 engages with the locking block 314 on the placement plate 24 through the inner locking post to form an outer protective structure to prevent the refractory brick from falling due to rotation or vibration, and at the same time assists in positioning the placement position of the refractory brick. When the drying is finished, the folding positioning block 311 is inserted into the positioning groove, and the spring pin 312 pops out and inserts into the round hole of the folding positioning block 311, so that the two lower pressure plates 36 are folded, making it easy to pick up the refractory brick and place the next batch of refractory bricks to be dried.
