Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate board production technology, specifically to an automated feeding device for calcium silicate board production slurry. Background Technology

[0002] Calcium silicate board is a board made by using loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials and siliceous and calcareous materials as the main binding materials. It is made by pulping, molding and accelerating the curing reaction in high temperature and high pressure saturated steam to form calcium silicate gel.

[0003] For example, a feeding device for an energy-saving calcium silicate board production line, disclosed in CN212126238U, achieves uniform mixing and quantitative feeding of slurry through the cooperation between the storage tank and the feeding tank; it saves manpower and improves process quality and efficiency; the time control device can control the hydraulic cylinder to work intermittently, without the hydraulic cylinder switch being constantly open, thus having a certain energy-saving effect.

[0004] In the above devices, when the slurry is transported through the connecting pipe, the fiber material in the slurry is prone to accumulate inside the connecting pipe. Over a long period of time, this accumulation can easily cause blockage inside the connecting pipe. The above devices do not perform regular cleaning of the inside of the connecting pipe. In addition, the feeding is controlled by valves, which requires the equipment to be adjusted every time it is used to ensure the feeding capacity. This is quite troublesome to use, and the staff needs to open and close the valves at all times. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an automated feeding device for calcium silicate board production slurry, which can periodically unclog the inside of the conveying pipe to avoid blockages, and can also perform quantitative feeding without prior debugging.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automated feeding device for calcium silicate board production slurry, comprising a storage tank and a motor mounted on the storage tank, a rotating shaft mounted on one side of the motor, and an array of stirring blades mounted on the rotating shaft, a conveying pipe passing through the storage tank, and a discharge tank mounted on the end of the conveying pipe away from the storage tank, and a metering component mounted on the discharge tank, the metering component being used to automatically meter the conveyed slurry to ensure consistent specifications of the produced calcium silicate boards;

[0009] The metering component includes a circular slide plate disposed inside the feeding tank, a support disposed on one side of the circular slide plate, a conical piston disposed on the other side of the support, and a rotating component movably disposed on the side of the circular slide plate away from the support.

[0010] Preferably, the storage tank is equipped with an air pump, the storage tank is equipped with a feed inlet, and the conveying pipe is equipped with a dredging component.

[0011] Preferably, the feeding tank has a discharge port on the side away from the conveying pipe and a fixing ring is provided inside. The feeding tank has symmetrically arranged matching grooves inside, and the matching grooves are slidably connected to the rotating component.

[0012] Preferably, the fixed ring is symmetrically provided with sliding rods, and the end of the sliding rod away from the fixed ring is fixedly connected to the circular sliding plate. The circular sliding plate is symmetrically provided with guide holes, and the sliding rod is covered with a first spring.

[0013] Preferably, the rotating assembly includes a sleeve disposed on one side of the circular slide plate, a fan-shaped sealing plate symmetrically disposed outside the sleeve, a mating rod disposed on the other side of the fan-shaped sealing plate, and a locking rod symmetrically disposed on the fan-shaped sealing plate, wherein the locking rod is slidably engaged with the circular slide plate, and further includes a torque spring disposed inside the sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This invention utilizes a gas conveying component to unclog the blockage of the fiber material inside the conveying pipe, allowing it to re-enter the storage tank. During the unblocking process, the operator can perform the operation at any time, preventing the conveying process from becoming unsmooth over a long period of use.

[0025] 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.

[0026] Example 1

[0027] Please see Figures 1 to 5This is the first embodiment of the present invention, which provides a technical solution: an automated feeding device for calcium silicate board production slurry, including a storage tank 1 and a motor 2 installed on the storage tank 1. A rotating shaft 21 is provided on one side of the motor 2, and stirring blades 22 are arranged in an array on the rotating shaft 21. The stirring blades 22 arranged in an array on the rotating shaft 21 have a certain bending angle to facilitate sufficient stirring of the slurry inside the storage tank 1. The slurry under sufficient stirring is transported from the conveying pipe 3 to the discharge tank 4. The conveying pipe 3 is installed through the storage tank 1 to transport the slurry, and the discharge tank 4 is provided at the end of the conveying pipe 3 away from the storage tank 1. A metering component 5 is provided on the discharge tank 4 to automatically meter the transported slurry to ensure that the specifications of the produced calcium silicate boards are consistent.

[0028] The metering component 5 includes a circular slide plate 51 disposed inside the feeding tank 4. The circular slide plate 51 is slidably connected to and fits together with the feeding tank 4. As the slurry on the circular slide plate 51 gradually increases, the circular slide plate 51 can be pressed down. A bracket 52 is disposed on one side of the circular slide plate 51, and a conical piston 53 is disposed on the other side of the bracket 52. The conical piston 53 is located inside the conveying pipe 3. When the bracket 52 connects the circular slide plate 51 and the conical piston 53, the conical piston 53 will move with the circular slide plate 51. When the circular slide plate 51 moves to a predetermined position, the conical piston 53 can block the outlet of the conveying pipe 3 to prevent excess slurry from entering the feeding tank 4. A rotating component 6 is movably disposed on the side of the circular slide plate 51 away from the bracket 52. The rotating component 6 is used to cooperate with the guide hole 54 opened on the circular slide plate 51. When the circular slide plate 51 descends to the point where it is about to reach the predetermined position, the rotating component 6 can rotate to open the guide hole 54 and quickly release the slurry on the circular slide plate 51 from the outlet 41.

[0029] An air pump 11 is installed on the storage tank 1. The air pump 11 is used to inflate the storage tank 1 with air to squeeze the slurry inside the storage tank 1 into the conveying pipe 3 for conveying. The storage tank 1 is provided with a feed inlet 12, which is used to replenish new slurry. When the feed inlet 12 is not opened, the entire storage tank 1 is in a closed state. A clearing component 7 is installed on the conveying pipe 3. The clearing component 7 is used to inflate and pressurize the conveying pipe 3 with air each time the conical piston 53 closes one end of the conveying pipe 3 to clear the blockage in the conveying pipe 3.

[0030] The feeding tank 4 has a discharge port 41 on the side away from the conveying pipe 3. The discharge port 41 is used to discharge material and has a fixing ring 42 inside. The fixing ring 42 is used to limit the downward position of the circular slide plate 51. The feeding tank 4 has symmetrically arranged matching grooves 43 inside, and the matching grooves 43 are slidably connected to the rotating component 6. The matching grooves 43 are a combination groove with vertical grooves and inclined grooves. When the circular slide plate 51 descends, it drives the rotating component 6 to move downward. Only when it is about to move to the predetermined position can the rotating component 6 rotate through the lower section of the matching grooves 43.

[0031] During operation, the slurry is first stored in the storage tank 1 through the inlet 12. Then, the inlet 12 is closed. Next, the motor 2 is started, causing the rotating shaft 21 to rotate. The rotation of the shaft 21 causes the stirring blades 22 to thoroughly stir the slurry. Then, the air pump 11 is started to continuously pump air into the storage tank 1 to pressurize it, forcing the slurry into the conveying pipe 3. The slurry is then sent into the discharge tank 4 through the conveying pipe 3. The circular slide plate 51 inside the discharge tank 4 holds the slurry. As slurry is continuously added, the circular slide plate 51 slowly moves downwards. When the circular slide plate 51 descends to a predetermined position, the conical piston 53 installed on the circular slide plate 51 releases the conveying fluid. One end of pipe 3 is sealed. At this time, the air pump 11 is turned off. Each time the conical piston 53 seals one end of the conveying pipe 3, the unblocking component 7 is activated to pressurize the inside of the conveying pipe 3 with air, flushing the blockage out of the conveying pipe 3 and into the storage tank 1 to complete the unblocking. When the circular slide plate 51 reaches the predetermined position, the rotating component 6 can be rotated to open the guide hole 54 on the circular slide plate 51 to quickly release the slurry. When the slurry on the circular slide plate 51 is quickly released, the circular slide plate 51 can be quickly reset by the first spring 56. During the reset process, the gas inside the storage tank 1 will be discharged from the storage tank 1 along with the conveying pipe 3 to restore its internal pressure, and then the next feeding process will begin.

[0032] Example 2

[0033] Please see Figures 1 to 6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0034] A sliding rod 55 is symmetrically arranged on the fixed ring 42. The sliding rod 55 is used to support the circular slide plate 51, and the end of the sliding rod 55 away from the fixed ring 42 is fixedly connected to the circular slide plate 51. The circular slide plate 51 is symmetrically provided with guide holes 54, which are used to quickly release the slurry on the circular slide plate 51. A first spring 56 is sleeved on the outside of the sliding rod 55. The first spring 56 is used to provide elastic force so that the circular slide plate 51 can be reset without being subjected to external force.

[0035] The rotating assembly 6 includes a sleeve 61 disposed on one side of the circular slide plate 51, and fan-shaped sealing plates 62 symmetrically disposed outside the sleeve 61. The fan-shaped sealing plates 62 are used to cooperate with the guide hole 54 and can completely close the guide hole 54 when not rotating. A cooperating rod 63 is disposed on the other side of the fan-shaped sealing plate 62 and is used to cooperate with the cooperating inclined groove 43 to restrict the rotation of the fan-shaped sealing plate 62 and prevent insufficient rotation angle. A locking rod 64 is symmetrically disposed on the fan-shaped sealing plate 62 and is slidably engaged with the circular slide plate 51. The assembly also includes a torque spring 65 disposed inside the sleeve 61. The torque spring 65 is used to drive the sleeve 61 to rotate and reset, so that the fan-shaped sealing plate 62 resets and closes the guide hole 54 again.

[0036] The unblocking assembly 7 includes an unblocking pump 71 installed on the delivery pipe 3, which is used to inflate the delivery pipe 3; an air vent 72 installed inside the delivery pipe 3, which is fixedly connected to the inner wall of the delivery pipe 3; a fixed cavity 73 installed on the other side of the air vent 72, which is used to cooperate with a sliding rod 75 to facilitate the sliding of the sliding rod 75; a second spring 74 installed inside the fixed cavity 73; a sliding rod 75 installed inside the fixed cavity 73, with one end of the sliding rod 75 engaged inside the fixed cavity 73; and a closing ring 76 installed on the other side of the sliding rod 75, which is used to fit against the inner wall of the delivery pipe 3 when the unblocking pump 71 is not activated, to prevent slurry from entering the unblocking assembly 7 during slurry delivery.

[0037] During use, as the circular slide plate 51 descends, the sleeve 61 connected to one side descends accordingly. The fan-shaped sealing plate 62 fixedly connected to the sleeve 61 can seal the guide hole 54 on the circular slide plate 51. When it reaches the predetermined position, the mating rod 63 fixedly connected to the fan-shaped sealing plate 62 engages with the mating groove 43. The sliding of the mating rod 63 can drive the fan-shaped sealing plate 62 to rotate, thereby opening the guide hole 54 on the circular slide plate 51 and allowing the slurry on the circular slide plate 51 to be quickly sent out of the feed tank 4 for subsequent processing. When the conical piston 53 closes one end of the conveying pipe 3, the unblocking pump 71 is started to push the sliding rod 75 to move. When the sliding rod 75 is displaced, the closure between the unblocking component 7 and the conveying pipe 3 can be opened. Then, air is continued to be injected to increase the pressure inside the conveying pipe 3, thereby flushing the blockage out of the conveying pipe 3 and completing the unblocking work.

[0038] The remaining structure is the same as that in Example 1.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
