Description

Technical Field

[0001] The invention relates to the technical field of gypsum preparation, in particular to an admixture adding device for gypsum preparation. Background Art

[0002] Gypsum is a traditional cementitious material with a long history of application. It is used in building materials and their products and has the advantages of light weight, heat preservation, sound absorption, good fire resistance, good decorativeness and processability, and low production energy consumption. Gypsum-based self-leveling mortar mainly uses gypsum as a cementitious material, adds special aggregates and various building chemical additives, and is mixed evenly to produce a dry mortar specially used for floor leveling.

[0003] Compared with cement-based self-leveling mortar, gypsum-based self-leveling mortar has the advantages of thermal insulation, sound absorption and fire prevention, good durability, no hollowing and cracking, etc. At present, three systems are mainly used for the preparation of gypsum self-leveling, namely high-strength gypsum, building gypsum and anhydrite. The gypsum self-leveling mortar prepared with high-strength gypsum has good strength but the cost is too high; the gypsum self-leveling mortar prepared with building gypsum has a lower cost but low strength. Adding water reducer to reduce the water-to-cement ratio and porosity, and then improve the strength of gypsum mortar is an effective technical approach. Therefore, various admixtures need to be added in sequence during the preparation of gypsum to improve the quality of gypsum.

[0004] Admixtures are generally divided into two forms: liquid and powder. In the process of adding powder admixtures, workers are often required to weigh the admixtures in advance and then pour them into the mixing device. This method is not only time-consuming and labor-intensive in repetitive work, but also has low work efficiency, which can easily lead to low accuracy in the amount of admixture input, affecting the quality of the finished gypsum product. At the same time, when in use, it is more time-consuming to add a large amount of admixture to the mixing device at one time and mix it with the gypsum raw materials by stirring. It may even be unevenly mixed and the product quality cannot be ensured to be stable. When the operator adds powdered raw materials to the mixing tank, a large amount of dust is likely to affect the health of the operator. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] like Figure 1-9As shown, an admixture adding device for gypsum preparation comprises: a base frame 1, a mixing tank 2 mounted on the base frame 1, a mixing assembly 3 arranged in the mixing tank 2, a feeding pipe 4 connected to the bottom of the mixing tank 2, a mounting sleeve 5 fixedly sleeved on the upper end of the mixing tank 2, a first bracket 6 and a second bracket 7 fixedly connected to the mounting ring, a liquid material adding assembly 8 arranged on the first bracket 6 and the mixing tank 2, a conveying assembly 9 arranged on the second bracket 7 and the mixing tank 2, two quantitative assemblies 10 mounted on the conveying assembly 9, two powder material feeding assemblies 11 respectively arranged on the two quantitative assemblies 10, and two intermittent feeding assemblies 12 respectively arranged on the two feeding assemblies and the quantitative assembly 10, wherein The mixing assembly 3 is suitable for stirring the powdery admixture and the liquid admixture that enter the mixing tank 2 and come into contact with the gypsum raw material; The liquid material adding component 8 is suitable for quantitatively adding a required amount of liquid additive into the mixing tank 2; The powder feeding assembly 11 is suitable for storing and feeding the powdery admixture to be used; The intermittent feeding component 12 is suitable for cooperating with the quantitative component 10 to intermittently convey the powdery admixture required to be input into the conveying component 9; The conveying component 9 is suitable for conveying the quantitative powdery admixture to the mixing tank 2. Before use, the staff will add the powdery admixtures and liquid admixtures to be used to the powder feeding component 11 and the liquid adding component 8 respectively. During operation, the required amount of gypsum raw materials is added to the mixing tank 2 through the set conveying component 9 in advance, and the gypsum raw materials in the mixing tank 2 are stirred and mixed under the control of the mixing component 3. In the process of stirring and mixing the gypsum raw materials, the order of adding the powdery admixtures and the liquid admixtures is determined according to the specific preparation method of the gypsum and the desired effect. When liquid admixture is needed, the liquid material adding component 8 can quantitatively deliver the required liquid admixture to the mixing tank 2 according to the order of adding the admixture, so that it is mixed with the gypsum raw material. After the liquid admixture is completely mixed with the gypsum raw material, when the powdery admixture is needed, the powdery material feeding component 11 storing the corresponding powdery admixture can be controlled to control the first solenoid valve 23 in the powdery material feeding component 11 to control the feeding pipe 22 to be unobstructed, and the powdery admixture is added to the quantitative tank 15 in the quantitative component 10. When the powdery admixture in the quantitative tank 15 reaches the required mass, The first solenoid valve 23 works to close the feed pipe 22, so as to achieve accurate collection of the required amount of powdery admixture. In the process of adding the powdery admixture, manual intervention can be greatly reduced, so as to ensure the accuracy of the amount of powdery admixture added in the subsequent mixing tank 2, save time and effort, and effectively improve work efficiency. At this time, under the control of the intermittent feeding component 12, the quantitative powdery admixture in the quantitative tank 15 can be intermittently dropped into the conveying component 9, and then, under the cooperation of the conveying component 9, the powdery admixture can be entered into the mixing tank 2 in small quantities and multiple times, so as to avoid the powdery admixture being added to the mixing tank at one time. The powdery admixture is mixed with the gypsum raw material in the mixing tank 2, which affects the efficiency and uniformity of the mixing of the powdery admixture and the gypsum raw material, ensures the quality of gypsum preparation, and in the intermittent feeding component 12, the reciprocating beating of the flapping rod 53 on the quantitative tank 15 can avoid the accumulation of powdery admixture in the quantitative tank 15, ensure that the powdery raw material in the quantitative tank 15 completely enters the mixing tank 2, and ensures the input quality of the powdery admixture; at the same time, when the powdery admixture is transported to the mixing tank 2 through the conveying component 9, the diffusion of the powdery admixture is effectively avoided, thereby avoiding the dust generated when the powdery admixture is added to affect the health of the staff.

[0022] Optionally, the quantitative component 10 includes a quantitative box 13 connected to the conveying component 9, a weighing plate 14 fixed in the quantitative box 13, a quantitative tank 15 movably mounted on the weighing plate 14, a quantitative tube 16 connected to the bottom of the quantitative tank 15, a limiter 17 fixedly sleeved on the outside of the quantitative tank 15, and a plurality of weight sensors 18 mounted on the weighing plate 14 and abutting against the limiter 17. When adding powdery admixtures, the powdery admixtures of the powder feeding component 11 will first fall into the quantitative tank 15 through the powder feeding component 11. Since the limiter 17 is pressed on the weight sensors 18, the weight sensors 18 can detect the weight change of the metering tank. When the powdery admixture dropped into the metering tank 15 reaches a certain weight, the powder feeding assembly 11 can be controlled to stop feeding the powdery admixture into the metering tank 15, thereby ensuring the accuracy of the amount of powdery admixture fed each time gypsum is prepared. The method is convenient to use, and when the metering assembly 10 is working, the rotation speed of the stirring shaft 20 in the powder feeding assembly 11 is reduced to avoid the discharge of the powdery admixture through the intermittent feeding assembly 12 when the metering assembly 10 is working.

[0023] Optionally, the powder feeding assembly 11 includes a feeding tank 19 fixed to the top of the quantitative assembly 10, a stirring shaft 20 rotatably connected in the feeding tank 19 and extending at one end into the quantitative assembly 10, a plurality of stirring rods 21 annularly fixedly connected to the stirring shaft 20, a feeding pipe 22 connected to the bottom of the feeding tank 19, and a first solenoid valve 23 installed on the feeding pipe 22; The quantitative tank 15 is arranged directly below the feeding pipe 22. After the powdery admixture to be used is added into the feeding tank 19, the stirring shaft 20 can drive the plurality of stirring rods 21 to rotate, so as to stir the powdery admixture in the feeding tank 19. Then, the first solenoid valve 23 controls the feeding pipe 22 to pass through. When the powdery admixture is discharged through the feeding pipe 22, the powdery admixture in the feeding tank 19 can be prevented from being blocked when being discharged through the feeding pipe 22, so that the powdery admixture can enter the quantitative tank 15 accurately and stably.

[0024] Optionally, the intermittent feeding assembly 12 includes a connecting frame 24 fixed to the bottom of the stirring shaft 20, a control ring 25 connected to the connecting frame 24, a movable tube 26 movably installed in the control ring 25, a connecting rod 60 fixedly connected to the movable tube 26 at one end and fixedly connected to the inner wall of the quantitative box 13 at the other end, and a feeding trough 27 opened on the control ring 25 and adapted to the movable tube 26; The metering tube 16 is movably and slidably inserted into the movable tube 26. When the powdery admixture of required weight enters the metering tank 15, the stirring shaft 20 controls the connecting frame 24 to drive the control ring 25 to rotate. At this time, the movable tube 26 moves relatively in the control ring 25. During the rotation of the control ring 25, the discharge chute 27 intermittently overlaps with the movable tube 26. When the powdery admixture in the metering tank 15 is discharged through the metering tube 16, it will intermittently pass through the movable tube 26 and the discharge chute 27 to enter the conveying component 9 for conveying, so that the powdery admixture can be intermittently put into the mixing tank 2, effectively improving the mixing effect of the powdery admixture and the gypsum raw material in the mixing tank 2.

When in use, when a powdery admixture or a liquid admixture is added into the mixing tank 2 and mixed with the gypsum raw material, the metering pump 31 can be started, and one of the second solenoid valves 34 can be controlled to make the extraction pipe 33 at the corresponding liquid supply tank 29 pass through, so that the liquid admixture in the liquid supply tank 29 is quantitatively delivered to the mixing tank 2 through the collecting pipe 32 and the delivery pipe 30, and the accuracy of the amount of liquid admixture added is ensured.

[0026] Optionally, the conveying assembly 9 includes a control box 35 fixed on the second bracket 7, two transmission wheels 36 rotatably connected to the control box 35, a transmission belt 37 sleeved on the two transmission wheels 36, a first motor 38 installed on the control box 35, a powder trough 39 opened at the bottom of the control box 35 and the upper surface of the mixing tank 2, and a feed hopper 40 connected to the top of the control box 35; The output end of the first motor 38 is fixedly connected to one of the transmission wheels 36. When in use, the first motor 38 is started to drive one of the transmission belts 37 to rotate, and then with the cooperation of the other transmission belt 37, the transmission belt 37 works, so that the powdery admixture that falls on the transmission belt 37 through the intermittent feeding component 12 can be transported to the powder trough 39 and put into the mixing tank 2, and the gypsum raw material can be transported by the transmission belt 37 into the mixing tank 2 after being put into the feed hopper 40.

The transmission toothed belt 47 on the wheel 46 can drive one of the driving gears 44 to rotate when the conveying assembly 9 is working and the transmission wheel 36 rotates, and then with the cooperation of the driving toothed belt 45, it meshes and transmits another driving gear 44 to drive the rotation, so that with the cooperation of the first bevel gear 42 and the second bevel gear 43, it meshes and transmits one of the stirring shafts 20, so that with the cooperation of the transmission toothed belt 47 and the two transmission gears 46, the other stirring shaft 20 is driven to rotate synchronously, so that the two powder feeding assemblies 11 and the intermittent unloading assembly 12 can work synchronously, without the need to use extra driving equipment, thereby reducing the use cost.

When the conveyor belt is transmitting and conveying the powdery admixture, the scraper 48 can scrape off the powdery admixture adhering to the transmission belt 37 to avoid the powdery admixture adhering to the transmission belt 37 and affecting the accuracy of the amount of the powdery admixture added. Under the push of a plurality of reset springs 51, the control frame 49 can push the scraper 48 to always keep in contact with the transmission belt 37 to avoid affecting the cleaning effect of the scraper 48 on the powdery admixture on the transmission belt 37.

When the powdery admixture is discharged from the quantitative tank 15 through the quantitative tube 16, the rotation of the stirring shaft 20 will drive the flapping rod 53 to intermittently flap the quantitative tank 15 to avoid accumulation of powdery admixture in the quantitative tank 15 and affect the accuracy of the amount of powdery admixture added. When the flapping rod 53 flaps the quantitative tank 15 and contacts the quantitative tank 15, since the flapping rod 53 is hinged to the driving ring 52, it can be detached from the quantitative tank 15 during the rotation process, and then reset by the control spring 55, so as to facilitate the flapping of the quantitative tank 15 by the flapping rod 53 next time.

At the same time, the rotation of the mixing shaft 57 will drive the auger 59 to rotate in the discharge pipe 4, so that the raw materials in the discharge pipe 4 can be transported to the mixing tank 2, so as to avoid the accumulation of raw materials in the discharge pipe 4 and affect the preparation quality of the gypsum. After the gypsum preparation is completed, the mixing shaft 57 drives the auger 59 to reverse, so as to ensure that the finished gypsum in the mixing tank 2 is discharged smoothly through the discharge pipe 4, so as to avoid the clogging of the finished gypsum at the discharge pipe 4.
