Description

Technical Field

[0001] The utility model relates to the technical field of dehydration, in particular to a raw material dehydration device for chemical production. Background Technique

[0002] The raw material dehydration device in chemical production is a key device for removing excess water in raw materials during the chemical production process. The water in the raw materials will not only affect the efficiency of subsequent reactions and the product quality, but may also cause corrosion and damage to production equipment. Therefore, raw material dehydration is an important link in chemical production.

[0003] The raw material dehydration technologies widely used in the chemical production field include, but are not limited to, heating evaporation, vacuum distillation, adsorption dehydration, and centrifugal dehydration, etc. Centrifugal dehydration uses centrifugal methods such as the rotation of the inner cylinder. Through the centrifugal force generated by high-speed rotation, the water contained in the object is thrown out, so as to achieve the purpose of dehydration. However, the dehydration effect on chemical raw materials is relatively weak, and it is easy to block the filter holes of the inner cylinder, making it inconvenient to use. Therefore, further optimization is made for the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a raw material dehydration device for chemical production, which solves the problems put forward in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A raw material dehydration device for chemical production, including a dehydration cylinder, a top cover, a support plate, an extrusion mechanism, an adjustment component, and a drive component;

[0006] The top cover is arranged at the opening at the top of the dehydration cylinder for maintaining airtightness. The adjustment component is arranged inside the cross plate of the dehydration cylinder and is movably connected to the right end of the support plate;

[0007] The extrusion mechanism includes an N-shaped frame fixedly connected to the upper surface of the top cover, an extrusion piece arranged on the upper surface of the N-shaped frame. The output end of the extrusion piece penetrates through the top cover and is sleeved with a pressing plate for extruding and dehydrating chemical raw materials;

[0008] A drainage cavity is arranged inside the dehydration cylinder, a drainage hole is arranged on the inner wall at the top, a heating plate is arranged on the inner wall at the bottom. A drainage port is opened on the outer wall at the bottom of the dehydration cylinder and is communicated with the drainage cavity;

[0009] A scraper is arranged inside the drainage cavity, near the drainage hole. A stirring rod is arranged below the support plate inside the dehydration cylinder. The drive component is arranged inside the dehydration cylinder and is used to drive the scraper and the stirring rod. A baffle is arranged at the bottom of the dehydration cylinder.

[0010] The utility model has the following beneficial effects:

[0011] 1. For the raw material dehydration device used in chemical production, the chemical raw materials to be dehydrated can be placed on the upper surface of the support plate inside the dehydration cylinder. The extrusion part drives the pressure plate to extrude the chemical raw materials for dehydration. The water after extrusion flows into the drainage cavity through the drainage holes and is discharged from the drainage port, thus completing the preliminary dehydration.

[0012] Subsequently, the adjustment component drives the support plate to retract into the inner part of the cross plate of the dehydration cylinder. The extruded chemical raw materials fall onto the part of the stirring rod. The driving component drives the stirring rod and the scraper to rotate, which is convenient for scraping the drainage hole part to reduce blockage. The heating plate can make the inner wall of the dehydration cylinder generate heat, so that the water in the chemical raw materials evaporates. With the cooperation of the stirring rod, the chemical raw materials are heated evenly, further improving the dehydration effect of the raw materials, and it is more convenient to use.

[0013] 2. For the raw material dehydration device used in chemical production, the lifting component on the outer wall of the dehydration cylinder can drive the top cover to move upward, which is convenient for opening the dehydration cylinder and facilitating the input of chemical raw materials.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 6 , the present invention provides a raw material dehydration device for chemical production; including a dehydration cylinder 1, a top cover 2, a support plate 3, an extrusion mechanism, an adjustment component, and a drive component;

[0023] The top cover 2 is arranged at the opening at the top of the dehydration cylinder 1 for maintaining the sealing property. The adjustment component is arranged inside the cross plate of the dehydration cylinder 1 and is movably connected to the right end of the support plate 3;

[0024] As Figure 1 shown, the bracket at the bottom of the outer wall of the dehydration cylinder 1 can support it, and a rubber pad is fixedly connected to the bottom of the bracket, which can reduce the vibration of the equipment. A limiting member is arranged at the top of the outer wall; including a fixed cylinder fixedly connected to the outer wall at the top of the dehydration cylinder 1 and a limiting plate inserted into the fixed cylinder and rotatable 360 degrees, the purpose of which is to limit the top cover 2 and maintain the stability during the use of the extrusion mechanism.

[0025] The extrusion mechanism includes an N-shaped frame 4 fixedly connected to the upper surface of the top cover 2, an extrusion member arranged on the upper surface of the N-shaped frame 4, and the output end of the extrusion member penetrates through the top cover 2 and is sleeved with a pressure plate 5 for extruding and dehydrating chemical raw materials;

[0026] As Figures 1 - 2 shown, both ends of the N-shaped frame 4 are fixedly connected to the edge of the top cover 2 to maintain the stability of the use of the extrusion member. Among them; the extrusion member includes a first motor 14 fixedly connected to the upper surface of the N-shaped frame 4, a threaded sleeve rod 15 is arranged at the output end of the first motor 14, and the bottom end of the threaded sleeve rod 15 is inserted into the inside of the pressure plate 5; the threaded sleeve rod 15 further includes a threaded cylinder and an inner rod;

[0027] When the first motor 14 is started to rotate forward, the inner rod is driven to rotate. At this time, the threaded cylinder drives the pressure plate 5 to move downward, which is convenient for extruding the raw materials above the support plate 3 inside the dehydration cylinder 1. When the first motor 14 rotates in reverse, the threaded cylinder drives the pressure plate 5 to move upward.

[0028] A drainage cavity 6 is arranged inside the dehydration cylinder 1, a drainage hole 7 is arranged on the inner wall of the top, a heating plate 10 is arranged on the inner wall of the bottom, and a drainage port 19 is opened on the outer wall at the bottom of the dehydration cylinder 1 and is communicated with the drainage cavity 6;

[0029] Inside the drainage cavity 6, near the drainage hole 7, there is a scraping plate 8. Inside the dehydration cylinder 1, below the support plate 3, there is a stirring rod 9. The driving assembly is arranged inside the dehydration cylinder 1 and is used to drive the scraping plate 8 and the stirring rod 9. At the bottom of the dehydration cylinder 1, there is a baffle 11 to prevent chemical raw materials from directly discharging from the bottom of the dehydration cylinder 1, facilitating the stirring by the stirring rod 9.

[0030] As Figures 1 - 3 shown, the number of drainage holes 7 is several, and they are evenly arranged at equal intervals on the inner wall of the top of the dehydration cylinder 1. When the pressing plate 5 squeezes the chemical raw materials, the water in the raw materials enters the inside of the drainage cavity 6 through the drainage holes 7, flows down, and discharges from the drainage port 19, thus completing the dehydration treatment of the chemical raw materials.

[0031] The driving assembly can drive the scraping plate 8 and the stirring rod 9 to rotate. Using the scraping plate 8 is convenient for cleaning the surface of the drainage hole 7, reducing the problem of chemical raw material blockage. The stirring rod 9 rotates, facilitating the stirring of the chemical raw materials to prevent the raw materials from sticking. When the heating plate 10 is powered on, the generated heat facilitates the evaporation of the chemical raw materials by heating, further improving the dehydration effect on the raw materials.

[0032] The inner bottom wall of the dehydration cylinder 1 is in a cross-shaped hollow shape. The bottom end of the stirring rod 9 penetrates the inner bottom plate of the dehydration cylinder 1, and on the surface inside the inner bottom plate, there is a bevel gear (shown in the figure, not labeled) fixedly connected. On the surface of the stirring rod 9 near the top end, there is a support rod, which is convenient for stirring the chemical raw materials to improve the stirring efficiency.

[0033] The adjusting assembly includes a driving block 12 fixedly connected to one end of the cross plate. The output end of the driving block 12 is fixedly connected with a screw rod 13. The left end of the screw rod 13 is threadedly connected with the support plate 3. The driving assembly includes a vertical rod 16 arranged inside the dehydration cylinder 1. On the side plate of the outer wall of the dehydration cylinder 1, there is a second motor 22 fixedly connected. The output end of the second motor 22 is fixedly connected with a connecting rod 21. The bottom end of the connecting rod 21 is threadedly connected with an auxiliary rod one 17. The right end of the auxiliary rod one 17 is threadedly connected with the bottom end of the vertical rod 16. Inside the dehydration cylinder 1, near the bottom end of the vertical rod 16, there is an auxiliary rod two 18 threadedly connected. The right end of the auxiliary rod two 18 is threadedly connected with the bottom end of the stirring rod 9.

[0034] As Figure 3 shown, the inner wall of the support plate 3 is provided with a thread meshing with the screw rod 13, which is convenient for driving the support plate 3 to move left and right. Starting the reverse rotation of the driving block 12 (using a motor or a motor as the power source) can drive the screw rod 13 to rotate self - rotatably. At this time, the support plate 3 moves to the left until it abuts against the clamping groove part on the inner wall of the dehydration cylinder 1, completing the separation of the upper and lower spaces of the dehydration cylinder 1, and at the same time facilitating the support of the chemical raw materials and the downward extrusion by the pressing plate 5.

[0035] As Figures 5 - 6As shown, the top end of the vertical rod 16 is a spur gear and the bottom end is a helical gear. The scraper 8 is annular and is arranged at the top of the drainage cavity 6. The scraper 8 includes two side rods extending from the bottom. Brushes are provided at the parts of the side rods close to the drainage holes 7. Helical gears that mesh with each other are provided at the bottom end of the connecting rod 21, both ends of the first auxiliary rod 17, and both ends of the second auxiliary rod 18. Tooth patterns are provided on the outer wall of the scraper 8 at the part close to the spur gear at the top end of the vertical rod 16, which is convenient for meshing connection with the spur gear;

[0036] Start the second motor 22, and synchronously drive the first auxiliary rod 17, the vertical rod 16, and the second auxiliary rod 18 to rotate through the connecting rod 21. Through the rotation of the vertical rod 16, the scraper 8 is synchronously driven to rotate, and the drainage holes 7 are cleaned by the brushes on the surface of the side plates; through the rotation of the second auxiliary rod 18, the stirring rod 9 is synchronously driven to rotate, which is convenient for stirring the chemical raw materials inside the dewatering cylinder 1.

[0037] A pressure sensor 20 is provided inside the support plate 3 and is used in cooperation with the pressure plate 5. An exhaust pipe is provided in the middle of the outer wall of the dewatering cylinder 1, which is convenient for the gas evaporated by the heating plate 10 to be discharged. A control module is provided on the upper surface of the horizontal plate on the outer wall of the dewatering cylinder 1 and is electrically connected to the pressure sensor 20. A lifting assembly is provided at the top of the outer wall of the dewatering cylinder 1, and the top end of the lifting assembly is fixedly connected to the N-shaped frame 4.

[0038] As Figure 3 shown, when the extrusion part drives the pressure plate 5 to extrude the chemical raw materials on the surface of the support plate 3, the pressure sensor 20 is squeezed. When the threshold value set by the pressure sensor 20 is reached, an electrical signal is sent to the control module. At this time, the control module controls the driving block 12 to start, thereby driving the support plate 3 to move into the dewatering cylinder 1 and the horizontal plate. At this time, the chemical raw materials on the upper surface of the support plate 3 fall into the space where the stirring rod 9 is located, which is convenient for stirring them.

[0039] The lifting assembly includes an electric telescopic rod fixedly connected to the outside of the top of the dewatering cylinder 1 and a connecting plate fixedly connected to the output end of the electric telescopic rod. The connecting plate is fixedly connected to the upper surface of the N-shaped frame 4 by bolts. When the electric telescopic rod rises, the N-shaped frame 4 is synchronously driven to rise through the connecting plate, which is convenient for opening the dewatering cylinder 1 and facilitating the input of chemical raw materials.

[0040] The first motor 14, the second motor 22, the driving block 12, the electric telescopic rod, the pressure sensor 20, etc. mentioned above are existing well-known technologies and are only cited here, and the specific structures will not be described in detail.

[0041] All the electrical components mentioned in this article are electrically connected to the external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0042] In the present invention, the working steps of the device are as follows:

[0043] During use, start the lifting component to drive the N-shaped frame 4 and the top cover 2 to rise, and put the chemical raw materials to be dehydrated into the interior of the dehydration cylinder 1. At this time, the support plate 3 is inside the dehydration cylinder 1. When an appropriate amount of chemical raw materials are put in, drive the top cover 2 to buckle on the top of the dehydration cylinder 1 again through the lifting component, and rotate the limit plate to limit the top cover 2. Then start the first motor 14, and drive the pressure plate 5 to move downward through the extrusion component to extrude the chemical raw materials. The water during extrusion flows from the drain holes 7 into the interior of the drain cavity 6 and is discharged from the drain port 19;

[0044] When the threshold value set by the pressure sensor 20 is reached, an electrical signal is sent to the drive block 12, thereby controlling the support plate 3 to contract into the interior of the dehydration cylinder 1 and the cross plate. At this time, the compressed chemical raw materials fall to the position of the stirring rod 9. The heating plate 10 is powered on, so that heat is generated inside the dehydration cylinder 1. Then start the second motor 22 to drive the connecting rod 21 to rotate, synchronously drive the scraping plate 8 and the stirring rod 9 to rotate, use the scraping plate ⑧ to clean the drain holes 7, and make the chemical raw materials heated evenly through the stirring rod 9. The evaporated water vapor is discharged from the exhaust pipe. At this time, the baffle 11 is inserted at the bottom of the dehydration cylinder 1 to prevent the chemical raw materials from falling. When the dehydration of the chemical raw materials by heating is completed, pull the baffle 11 to take out the dehydrated chemical raw materials.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
