Technical Field

[0001] The present application relates to the technical field of feeding devices, and in particular to a chemical safety feeding device. Background Art

[0002] In the chemical production process, it is often necessary to put some powdered reactants into a reactor for reaction. In the prior art, there is a situation where a manual reactor is needed to feed materials. When adding materials, sometimes the reaction is violent and the materials will splash. When feeding, if the reaction container is opened rashly to feed materials, there is a safety hazard.

[0003] The Chinese utility model patent with publication number CN221062631U discloses a safe feeding device for chemical production, which feeds powder into a reactor through a feeding port by setting a push-type frame, so as to achieve the purpose of safe feeding. However, in actual use, the material is guided by the feeding pipe port and will be relatively concentratedly fed to a certain position of the reaction liquid in the reactor, which may cause local heating of the reaction liquid and rapid accumulation of heat, posing a great safety hazard.

[0004] Therefore, the present application provides a chemical safety feeding device to solve the above problems. Utility Model Content

[0005] The present application provides a chemical safety feeding device, which aims to solve the problems of the existing safety feeding device mentioned in the background technology. When feeding, the material is guided by the feeding pipe mouth and will be relatively concentratedly fed to a certain position of the reaction liquid in the reactor, which may cause local heating of the reaction liquid, rapid accumulation of heat, and great safety hazards.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a chemical safety feeding device, comprising an operating table and a conveying bin fixedly mounted on the operating table, a feed port fixedly mounted on the top of the conveying bin, and a discharge port fixedly mounted on the bottom of the conveying bin, one end of the conveying bin is fixedly mounted with a drive motor on the top of the operating table, an auger penetrating into the conveying bin is fixedly mounted on the output end of the drive motor, and a dispersed unloading mechanism is arranged on the end of the conveying bin away from the drive motor;

[0007] The dispersing material discharging mechanism comprises an extension shaft fixedly mounted on the auger away from one end of the driving motor and extending through the conveying bin outside the conveying bin, the end of the extension shaft is fixedly mounted with a bevel gear 1, the bevel gear 1 is meshed with a bevel gear 2, the bevel gear 2 is fixedly mounted with a rotating shaft, the bottom end of the rotating shaft is fixedly mounted with a scraper, a hopper fixedly connected to a discharge port is arranged below the scraper, a plurality of evenly arranged discharge holes are arranged at the bottom of the hopper, so that the material is introduced into the conveying bin through the feed port, and then the driving motor is started to drive the auger to rotate, the material is transported to the discharge port for discharge, and the material enters the hopper, and at the same time, the bevel gear 1 drives the bevel gear 2 to rotate, and the rotating shaft drives the scraper to rotate at the bottom of the hopper to spread the material and drop it into the reaction container through the discharge hole, so as to avoid the material from accumulating at a certain concentrated position of the reaction liquid and avoid the local rapid heating to generate high heat, thereby ensuring the safe progress of the reaction work.

[0008] Preferably, in order to spread the material, the scraper element includes a ring fixedly mounted on the outer wall of the bottom end of the rotating shaft, and a plurality of circumferentially evenly distributed angle scraping strips are fixedly mounted on the outer wall of the ring. The plurality of angle scraping strip rings rotate on the rotating shaft, and the angle scraping strips are circumferentially selected in the direction of the angle protrusion to spread the material and avoid accumulation.

[0009] Preferably, in order to ensure that the material can be evenly spread in the lower hopper, several of the angle scrapers are arranged in the same rotation direction, and the discharge end of the discharge port extends into the lower hopper and is aligned with the corner of the angle scraper. The material falls on the lower hopper through the discharge port at a position of half the diameter, which corresponds to the angle scraper. When several of the angle scrapers rotate toward one side of the angle protrusion, the angle will spread the material to both sides, so as to spread the material as evenly as possible and avoid accumulation.

A water pump is arranged between the water tank and the condenser, and the water pump is provided with a cold water pipe connecting the water tank and the condenser and passing through the support. The water pump is connected to the water tank through the cold water pipe. After the water pump inputs cold water into the cold water pipe, the cold water pipe takes away the heat generated in the conveying bin at the bottom of the conveying bin in the support, thereby ensuring that the conveying bin is in a constant temperature state, avoiding accidents caused by temperature increase, and ensuring feeding safety.

[0012] Preferably, in order to support the conveying bin, a plurality of thermal conductive seats mounted on the outer wall of the cold water pipe are fixedly installed in the support, and a thermal conductive support plate in contact with the bottom of the conveying bin is fixedly installed on the top of the thermal conductive seat.

[0013] The feeding device introduces the material into the conveying bin through the feed port, then starts the driving motor to drive the auger to rotate, and transports the material to the discharge port for discharge. The material enters the lower hopper. At the same time, the bevel gear one drives the bevel gear two to rotate, and the rotating shaft drives the scraper to rotate at the bottom of the lower hopper to spread the material and drop it into the reaction container through the discharge hole, so as to avoid the accumulation of material in a certain concentrated position of the reaction liquid and avoid local rapid heating to generate high heat, thereby ensuring the safe progress of the reaction work.

[0014] The feeding device is connected to the water tank through a cold water pipe. After the water pump inputs cold water into the cold water pipe, the cold water pipe takes away the heat generated in the conveying bin at the bottom of the conveying bin in the support, ensuring that the conveying bin is in a constant temperature state, avoiding accidents caused by temperature increase, and ensuring the safety of feeding.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a chemical safety feeding device, such as Figure 1-5 As shown, the feeding device includes an operating table 1 and a conveying bin 2 fixedly mounted on the operating table 1, a feeding port 3 fixedly mounted on the top of the conveying bin 2, and a discharging port 4 fixedly mounted on the bottom of the conveying bin 2. A driving motor 5 is fixedly mounted on one end of the conveying bin 2 at the top of the operating table 1, an auger 6 penetrating into the conveying bin 2 is fixedly mounted on the output end of the driving motor 5, and a dispersing unloading mechanism 7 is arranged on the end of the conveying bin 2 away from the driving motor 5;

[0025] The dispersed unloading mechanism 7 includes an extension shaft 71 which is fixedly mounted on the auger 6 at one end away from the driving motor 5 and passes through the conveying bin 2 and extends to the outside of the conveying bin 2. A bevel gear 1 72 is fixedly mounted on the end of the extension shaft 71. A bevel gear 2 73 is meshed on the bevel gear 1 72. A rotating shaft 74 is fixedly mounted on the bevel gear 2 73. A scraper 75 is fixedly mounted on the bottom end of the rotating shaft 74. A unloading hopper 76 fixedly connected to the discharge port 4 is arranged below the scraper 75. A plurality of evenly arranged unloading holes 77 are provided at the bottom of the unloading hopper 76.

[0026] When in use, the material is introduced into the conveying bin 2 through the feed port 3, and then the drive motor 5 is started to drive the auger 6 to rotate, and the material is conveyed to the discharge port 4 for discharge, and the material enters the lower hopper 76. At the same time, the bevel gear 1 72 drives the bevel gear 2 73 to rotate, and the rotating shaft 74 drives the scraper 75 to rotate at the bottom of the lower hopper 76 to spread the material and drop it into the reaction container through the discharge hole 77, so as to avoid the material from accumulating in a certain concentrated position of the reaction liquid and to avoid local rapid heating to generate high heat, thereby ensuring the safe progress of the reaction work.

[0027] Specifically, the scraper 75 includes a collar 751 fixedly mounted on the outer wall of the bottom end of the rotating shaft 74, and a plurality of circumferentially evenly distributed angle scraper strips 752 are fixedly mounted on the outer wall of the collar 751. When in use, the collar 751 with the angle scraper strips 752 rotates on the rotating shaft 74, and the angle scraper strips 752 perform circumferential selection in the direction of the angle protrusion to spread the material and avoid accumulation.

[0028] More specifically, a plurality of folded scraper strips 752 are arranged in the same rotation direction, and the discharge end of the discharge port 4 extends into the lower hopper 76 and is arranged above the folded corner of the folded scraper strip 752. When in use, the material falls through the discharge port 4 onto the lower hopper 76 at a position of half the diameter, which just corresponds to the folded scraper strip 752. When the plurality of folded scraper strips 752 rotate toward the folded corner protrusion, the folded corner will spread the material to both sides, thereby spreading the material as evenly as possible to avoid accumulation.

[0029] Furthermore, a mounting plate 78 is fixedly mounted on the outer wall of one end of the conveying bin 2 close to the extension shaft 71, a support rod 79 is fixedly mounted on the outer wall of the mounting plate 78, and a bearing 710 sleeved on the outer wall of the rotating shaft 74 is fixedly mounted on the end of the support rod 79 away from the mounting plate 78. When in use, the mounting plate 78 is fixed to the side wall of the conveying bin 2 by bolts, the bearing 710 is supported by the support rod 79, and the rotating shaft 74 is installed in the bearing 710 to ensure rotation, which is convenient and fast.

[0030] Example 2

[0031] Different from Example 1, during the process of conveying materials in the conveying bin 2, the heat generated by the accumulation of materials and the movement of the auger 6 may affect the feeding safety. For this reason, the feeding device also includes a constant temperature mechanism 8, which includes a support 81 installed at the bottom of the conveying bin 2 and fixed to the top of the operating table 1, and a water tank 82 and a condenser 83 arranged on the operating table 1. A water pump 84 is arranged between the water tank 82 and the condenser 83, and the water pump 84 is provided with a cold water pipe 85 that connects the water tank 82 and the condenser 83 and passes through the support 81.

[0032] When in use, the cold water pipe 85 is connected to the water tank 82. After the water pump 84 inputs cold water into the cold water pipe 85, the cold water pipe 85 takes away the heat generated in the conveying bin 2 at the bottom of the conveying bin 2 in the support 81, ensuring that the conveying bin 2 is in a constant temperature state, avoiding accidents caused by temperature increase, and ensuring the safety of feeding.

[0033] Specifically, a plurality of heat-conducting seats 86 sleeved on the outer wall of the cold water pipe 85 are fixedly installed in the support 81, and a heat-conducting support plate 87 in contact with the bottom of the conveying bin 2 is fixedly installed on the top of the heat-conducting seat 86. When in use, the outer wall of the cold water pipe 85 is connected to the heat-conducting seat 86 to support the cold water pipe 85, and then the heat-conducting support plate 87 is connected to the heat-conducting seat 86 to support the bottom of the conveying bin 2, thereby expanding the contact area and improving the heat dissipation efficiency.

[0034] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
