Description

TECHNICAL FIELD

[0001] The present scheme belongs to the technical field of gypsum mortar equipment, and particularly relates to a production device for preparing pre-mixed plastering mortar by using by-product gypsum of aluminum electrode foil. BACKGROUND

[0002] The aluminum electrode foil is mainly used in the production process of electrolytic aluminum as an anode material. In the production process, fluorinated salt is used as electrolyte, resulting in waste slag containing calcium sulfate (CaSO4) and other impurities. The main component of by-product gypsum is calcium sulfate dihydrate (CaSO4·2H2O), but also contains a certain amount of fluoride, heavy metal ions and other mineral impurities. Due to the existence of various impurities, direct use of by-product gypsum may affect the performance of the final product.

[0003] At present, a phosphogypsum heat treatment impurity removal device with the announcement number CN116835627A is on the market. The impurity removal device is provided with a consumption reduction feeding and discharging mechanism, so that whether the phosphogypsum is added into the calcination kettle or discharged from the calcination kettle, the calcination kettle can be kept in a sealed state, thereby greatly reducing the heat loss, effectively reducing the energy consumption, improving the defects of the heat treatment method, improving the practicability of the heat treatment method, and popularizing the application of the heat treatment method in phosphogypsum impurity removal. Through the setting of the stretching discharging mechanism, when the phosphogypsum is taken out from the net-shaped material containing cylinder, the heat of the phosphogypsum can make the hot stretching plug rod stretch due to the restoration to the high-temperature phase shape. The stretching of the hot stretching plug rod will push the control discharge plug, so that the phosphogypsum in the net-shaped material containing cylinder can flow from the connection between the original control discharge plug and the outer wall of the net-shaped material containing cylinder into the discharging pipe and be discharged directionally through the discharging pipe, thereby improving the work efficiency and greatly improving the practicability.

[0004] However, there is a problem that the gypsum contains large particle gypsum, which is not easy to mix with cement and other substances, so screening is needed. However, the existing screening devices are all vibrating screens for screening. However, the large particle gypsum is easy to accumulate on the vibrating screen, causing the screen to be blocked. CONTENT OF THE INVENTION

[0005] The present scheme provides a production device for preparing pre-mixed plastering mortar by using by-product gypsum of aluminum electrode foil, which is used to solve the problem of screen blockage during gypsum screening.

[0006] The present scheme provides a production device for preparing pre-mixed plastering mortar by using by-product gypsum of aluminum electrode foil, which comprises

[0007] Screening device: for removing oversized gypsum;

[0008] Crushing device: for crushing gypsum;

[0009] Stirring device: for mixing and preparing mortar;

[0010] The crushing device, the screening device and the stirring device are connected in sequence.

[0011] The screening device comprises:

[0012] Conveyer belt: used for transporting gypsum;

[0013] Vibrating screen: the vibrating screen is matched with the conveyer belt, and the vibrating screen is at an angle with the conveyer belt.

[0014] Collecting box: used for collecting screened gypsum and unqualified gypsum, and the collecting box is matched with the vibrating screen.

[0015] The principle of the scheme is that the operator manually washes the by-product gypsum, then puts the gypsum on the conveyer belt, starts the conveyer belt, and the gypsum is sent to the vibrating screen which is downwardly inclined in sequence, the vibrating screen is started to screen the gypsum, the suitable gypsum passes through the vibrating screen, and the large-particle gypsum falls from the vibrating screen due to gravity and vibration, preventing the large-particle gypsum from being stuck on the vibrating screen.

[0016] The beneficial effect of the scheme is that the scheme prevents the problem of large-particle gypsum being stuck on the vibrating screen by the downward inclination of the vibrating screen and gravity.

[0017] Further, the conveyer belt comprises a conveyer belt, a conveyer motor, a rack, a support leg and a conveyer roller, the rack is fixedly connected with the support leg, and the vibrating screen is slidably connected with the rack, the conveyer motor is fixedly connected with the rack, and the shaft of the conveyer motor is fixedly connected with the conveyer roller, the conveyer belt is matched with the conveyer roller, and the vibrating screen is matched with the conveyer belt.

[0018] The conveyer belt bears and transports the gypsum raw material. The conveyer motor provides a power source to drive the conveyer roller to rotate. The rack supports the entire conveyer belt system and provides a mounting base for each component. The rack is fixedly connected with the support leg to ensure the stability of the system, and is slidably connected with the vibrating screen to allow the vibrating screen to move within a certain range.

[0019] The support leg supports the rack to ensure the stability and levelness of the entire system. The conveyer roller serves as a support and driving component of the conveyer belt.

[0020] The operator starts the conveying motor, and the motor starts running. The shaft of the conveying motor drives the conveying roller to rotate through a coupling or direct connection. The rotation of the conveying roller drives the conveying belt to move through friction, causing the conveying belt to start running. The gypsum raw material is placed at one end of the conveying belt, usually referred to as the feeding end. As the conveying belt moves, the gypsum is gradually transported to the other end, usually referred to as the discharging end, which is the position of the vibrating screen. When the gypsum reaches the end of the conveying belt, it falls off due to gravity and falls into the vibrating screen. The vibrating screen screens the gypsum through its own vibration mechanism. Fine qualified particles fall into the collection device through the screen, while larger particles or impurities fall from the lower side of the screen under the action of gravity.

[0021] Further, it further comprises a suction cup fixedly connected with the supporting leg. The suction cup is adsorbed on the ground or the installation platform, which enhances the stability of the whole system and reduces the vibration transmission to the supporting leg and the rack when the vibrating screen is working.

[0022] Further, it further comprises a baffle fixedly connected with the rack and matched with the conveying belt. The baffle is installed on both sides or around the conveying belt, effectively preventing the gypsum and other materials from overflowing from the conveying belt during transportation. The baffle ensures that the materials are completely constrained within the conveying belt, avoiding waste and pollution of the working environment.

[0023] Further, the screening device is provided with a dedusting mechanism, which comprises a dedusting belt, a magnet, a dedusting motor and a dedusting roller. The dedusting belt is matched with the vibrating screen and the conveying belt. The shaft of the dedusting motor is fixedly connected with the dedusting roller. The dedusting motor is fixedly connected with the rack. The dedusting roller is matched with the dedusting belt. The magnet is matched with the dedusting belt. The magnet is fixedly connected with the rack.

[0024] Since the aluminum electrode by-product gypsum contains metal impurities, if not removed, it will cause poor effect of the mortar when preparing the mortar. When the conveying belt transports the gypsum, it will first fall on the dedusting belt. Since the magnet is located below the dedusting belt, the magnet adsorbs the metal substances, so that the metal substances adhere to the dedusting belt, and the gypsum will continue to fall due to gravity and fall on the vibrating screen.

[0025] When the metal substances adhere too much, the operator can start the dedusting motor at this time, so that the dedusting belt moves with the metal substances. When moving to the outside of the vibrating screen mesh, there is no magnet here, the metal substances will lose the adsorption force and directly fall outside the screen mesh, so that the metal impurities will not accumulate on the dedusting belt.

[0026] Further, the collecting box comprises a large particle box, a small particle box and a metal box, which are fixedly connected with each other, the large particle box and the small particle box are matched with the vibrating screen, and the metal box is matched with the impurity removing belt. The small particle box is located directly below the vibrating screen, the large particle box is located behind the vibrating screen, and the metal box is located on the left and right sides of the vibrating screen. After the gypsum passes through the conveying belt, it is divided into three types under the action of the impurity removing mechanism and the vibrating screen, the large particle gypsum falls into the large particle box, the small particle gypsum falls into the small particle box, and the metal impurities fall into the metal box, thereby completing the classification.

[0027] Further, the washing device is further arranged, which is used for washing the gypsum and is connected with the screening device. Before screening, the operator needs to wash the gypsum, so as to remove some soluble impurities and reduce the gypsum dust, thereby ensuring the health of the operator.

[0028] Further, the calcining device is further arranged, which is used for removing the crystal water of the gypsum and is fixedly connected with the screening device. The main function of the calcining device is to remove the crystal water of the gypsum and convert it into hemihydrate gypsum (CaSO4·0.5H2O). The generated hemihydrate gypsum has better hydration performance and bonding force, and is suitable for preparing high-quality ready-mixed plaster mortar. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0033] As shown in the accompanying Figure 1 drawings:

[0034] The scheme provides a production device for preparing pre-mixed plastering mortar by using aluminum electrode foil by-product gypsum, which comprises a washing device, a screening device, a crushing device, a calcining device and a stirring device. The washing device is used for cleaning the gypsum. Before screening, the operator needs to clean the gypsum in order to remove some soluble impurities and reduce the gypsum dust, thereby ensuring the health of the operator.

[0035] The screening device is used for removing oversized gypsum. The calcining device is used for removing the crystal water of the gypsum. The main function of the calcining device is to remove the crystal water in the gypsum and convert it into hemihydrate gypsum (CaSO4•0.5H2O). The generated hemihydrate gypsum has better hydration performance and bonding force, and is suitable for preparing high-quality pre-mixed plastering mortar.

[0036] The stirring device is used for mixing and preparing the mortar. When stirring, a certain amount of gypsum powder, cement, fine sand and additives are added, and then low-speed and large-torque stirring is performed.

[0037] As shown in Figure 1 , Figure 2 ,

[0038] The screening device comprises a conveying belt, a vibrating screen 7, a collection box and a dedusting mechanism. The conveying belt is used for transporting the gypsum. The conveying belt comprises a conveying belt 1, a conveying motor 4, a rack, a supporting leg 5 and a conveying roller. The rack is fixedly connected with the supporting leg 5, the vibrating screen 7 is slidably connected with the rack, the conveying motor 4 is fixedly connected with the rack, and the conveying motor 4 is fixedly connected with the conveying roller through a speed reducer 3. The conveying belt 1 wraps the conveying roller. The vibrating screen 7 is located below the conveying belt 1, and the gypsum on the conveying belt 1 falls down and falls on the vibrating screen 7. The vibrating screen 7 is inclined downward at an angle of 30° with respect to the conveying belt 1. It also comprises a supporting plate 13, which is fixedly connected with the rack and arranged below the conveying belt 1 to support the conveying belt 1.

[0039] It also comprises a suction cup 6, which is fixedly connected with the supporting leg 5. The suction cup 6 is adsorbed on the ground or the mounting platform, thereby enhancing the stability of the whole system and reducing the vibration generated by the vibrating screen 7 from being transmitted to the supporting leg 5 and the rack.

[0040] It also comprises a baffle 2, which is fixedly connected with the rack and cooperates with the conveying belt 1. The baffle 2 is installed on both sides or around the conveying belt 1, thereby effectively preventing the gypsum and other materials from overflowing from the conveying belt 1 during the conveying process. The baffle 2 ensures that the materials are completely constrained in the conveying belt 1, thereby avoiding waste and polluting the working environment.

[0041] As shown in Figure 2 , Figure 3 ,

[0042] The collecting box comprises a large particle box 10, a small particle box 11 and a metal box 14, the large particle box 10, the small particle box 11 and the metal box 14 are fixedly connected with each other, the large particle box 10 and the small particle box 11 are matched with the vibrating screen 7, and the metal box 14 is matched with the impurity removing belt 9. The small particle box 11 is located directly below the vibrating screen 7, the large particle box 10 is located behind the vibrating screen 7, and the metal box 14 is located on the left and right sides of the vibrating screen 7. When the gypsum passes through the conveying belt, it will be divided into three categories under the action of the impurity removing mechanism and the vibrating screen 7, the large particle gypsum will fall into the large particle box 10, the small particle gypsum will fall into the small particle box 11, and the metal impurities will fall into the metal box 14, thereby completing the classification.

[0043] The impurity removing mechanism comprises the impurity removing belt 9, the magnet 12, the impurity removing motor and the impurity removing roller. The impurity removing belt 9 is located above the vibrating screen 7 and is parallel to the vibrating screen 7. The impurity removing belt 9 is located below the transmission belt. When the material is conveyed, the material first falls on the impurity removing belt 9 and then falls on the vibrating screen 7.

[0044] The shaft of the impurity removing motor is fixedly connected with the impurity removing roller. The impurity removing roller is rotatably connected with the vibrating screen 7 through the connecting rod 8. The impurity removing roller is located above the vibrating screen 7. The impurity removing motor is fixedly connected with the rack. The impurity removing belt 9 wraps the impurity removing roller. The magnet 12 is slightly shorter than the impurity removing belt 9 and has the same width as the vibrating screen 7. The magnet 12 is located below the impurity removing belt 9 and is in contact with the impurity removing belt 9. The magnet 12 is fixedly connected with the rack.

[0045] As shown in Figure 1 , Figure 2 , Figure 3 ,

[0046] The principle of the scheme is that the operator first removes the impurities, such as metal scraps and dust, attached to the by-product gypsum by the washing device.

[0047] Then the operator places the gypsum on the conveying belt and starts the conveying belt. The gypsum first falls on the impurity removing belt 9. Since the magnet 12 is located below the impurity removing belt 9, the magnet 12 adsorbs the metal substances, so that the metal substances adhere to the impurity removing belt 9. The gypsum continues to fall due to gravity and falls on the vibrating screen 7.

[0048] When the metal substances adhere too much, the operator can start the impurity removing motor to move the impurity removing belt 9 with the metal substances. When the impurity removing belt 9 moves to the outside of the vibrating screen 7, there is no magnet 12, so the metal substances lose the adsorption force and directly fall into the metal box 14 outside the screen, thereby preventing the metal impurities from accumulating on the impurity removing belt 9.

[0049] When the gypsum falls on the downwardly inclined vibrating screen 7, the vibrating screen 7 is started, and the gypsum is screened, and the suitable gypsum can pass through the vibrating screen 7 and fall into the small particle box 11, and the large particle gypsum can fall from the lower side of the vibrating screen 7 into the large particle box 10 due to gravity and vibration, preventing the large particle gypsum from being blocked on the vibrating screen 7, and realizing screening.

[0050] For the larger particle by-product gypsum, it is mechanically crushed into smaller particles by the crushing device. The by-product gypsum is sent into the calcining device for calcining at 120°C to 170°C, and the calcining time is adjusted according to the calcining equipment and the characteristics of the raw material, to ensure sufficient dehydration but not over-burning. High-temperature calcining can remove fluoride, moisture and other volatile impurities, and improve the purity and stability of the gypsum.

[0051] Then the dry gypsum powder, cement and fine sand are added into the mixer according to the proportion. An appropriate amount of water and other liquid additives are added, and the mixer is started. After uniform stirring, it is ensured that the ingredients are fully mixed to form a uniform mortar. A low-speed mixer is used, and the water and other liquid ingredients are gradually added to reduce air mixing; after the stirring is completed, the mixture is left for a few minutes to allow the bubbles to naturally rise and break. Finally, the mortar is obtained.

[0052] The gypsum is classified into three types under the action of the dedusting mechanism and the vibrating screen 7, the large particle gypsum falls into the large particle box 10, the small particle gypsum falls into the small particle box 11, and the metal impurities fall into the metal box 14, and the classification is completed, so that the gypsum is not mixed.

[0053] The above-mentioned is only an embodiment of the present application, and the well-known specific structure and characteristics in the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be regarded as the protection range of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
