Description

Technical Field

[0001] The utility model relates to the technical field of reactor cooling devices, in particular to a reactor for pyrazole production equipped with a cooling device. Background Art

[0002] A reactor is a container used to carry out chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are achieved.

[0003] For example, patent publication number CN212284012U discloses a cooling device for a reactor used in the production of pyrazole alcohol, which relates to the technical field of reactor cooling devices. A cooling device for a reactor used in the production of pyrazole alcohol comprises a base, a water pump fixedly mounted on one side of the base, a water inlet pipe fixedly mounted on the top of the water pump, a first external water pipe fixedly mounted on the top of the base and a reactor body, the water pump and the first external water pipe being interconnected inside the base, a reduction motor fixedly mounted on the top of the reactor body, a feed pipe fixedly mounted on the top of the reactor body, a second external water pipe fixedly mounted on the outer wall of the reactor body, and a water outlet pipe fixedly disposed on the bottom of the reactor body.

[0004] Through the above configuration, the utility model described in the prior art achieves the heat exchange effect of the reactor body by providing a heat exchange disc. The coordinated configuration of the water inlet pipe, the external water pipe, and the water outlet pipe achieves the effect of unidirectional water flow, which is conducive to removing heat and improving the cooling effect of the device. However, the cooling device of the reactor of the prior art solution has the following defects during operation:

[0005] When in use, the above-mentioned device only continuously adds water to the interior of the heat exchange disc through a water pump, so that water continuously circulates inside the heat exchange disc, thereby achieving the cooling of pyrazolol. However, the water circulating in this process cannot be replaced and reused, and a large amount of water is required. Moreover, water at room temperature is not effective for the cooling of pyrazolol production, and a long time is required to achieve the cooling of pyrazolol. Moreover, the device only collects pyrazolol through the discharge pipe, and pyrazolol cannot automatically enter the interior of the discharge pipe, thereby causing technical problems such as difficulty in collecting pyrazolol. Utility Model Content

[0006] The utility model aims to provide a reaction kettle for producing pyrazolol with a cooling device, which is mainly used to solve the technical problems of slow cooling speed and difficulty in collecting pyrazolol in the prior art.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A reactor for producing pyrazolol with a cooling device comprises a bottom plate, the top of the bottom plate is fixedly connected to a reactor body, the inner side wall of the reactor body is fixedly connected to a fixed plate, the top of the reactor body is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating rod, and the bottom of the rotating rod is rotatably connected to the top of the fixed plate, the outer side wall of the rotating rod is fixedly connected to a plurality of stirring rods, the inner side wall of the reactor body is fixedly connected to a heat exchange disk, the top of the fixed plate is provided with a discharge port, the bottom of the fixed plate located at the discharge port is fixedly connected to a discharge pipe, the lower side wall of the reactor body is fixedly connected to a cooling assembly, the top of the fixed plate is slidably connected to an arc-shaped scraper, the side wall of the arc-shaped scraper is provided with a mounting groove, and the inner side wall of the mounting groove is slidably connected to an adjustment assembly.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When using this device, first place the raw materials of pyrazolol inside the reactor body, then start the motor, use the rotating rod to drive the stirring rod to work, so as to stir the pyrazolol, then start the cooling component, and use the cooling component to cool the pyrazolol inside the reactor body. Finally, by adjusting the adjustment component, the arc scraper and the rotating rod are preliminarily connected. When the rotating rod rotates, it will drive the arc scraper to slide along the top of the fixed plate, thereby pushing the pyrazolol on the top of the fixed plate to the position of the discharge port, and finally the processed pyrazolol can be discharged through the discharge pipe.

[0011] 2.Beneficial effects:

[0012] The prior art achieves the effect of unidirectional water flow by setting up a water inlet pipe, an external water pipe and a water outlet pipe, which is conducive to taking away heat and improving the cooling effect of the device. However, the prior art has technical problems such as slow cooling speed and difficulty in collecting pyrazolol. The present solution uses a cooling component to allow a cooler liquid to circulate inside the heat exchange disc, thereby making the cooling speed of pyrazolol faster, thereby increasing the work efficiency of pyrazolol production. The adjustment component is set up so that when collecting pyrazolol, the device can drive the arc scraper to rotate through the rotating rod, so that the arc scraper is used to push the pyrazolol to the discharge port, thereby achieving the technical problem of rapid collection of pyrazolol.

[0013] Preferably: the cooling assembly includes a refrigeration component fixedly connected to the lower side wall of the reactor body, the outer side wall of the reactor body is connected to a water pump, the output end of the water pump is fixedly connected to an input pipe, and the other end of the input pipe is connected to the heat exchange disc, the other end side wall of the heat exchange disc is connected to an output pipe, and the other end of the output pipe is connected to the reactor body. When it is necessary to cool the pyrazolol inside the reactor body, the water at the bottom of the reactor body is cooled by the refrigeration component by starting the water pump and the refrigeration component, and then the water with lower temperature is transferred from the input pipe to the inside of the heat exchange disc by the water pump, and the liquid inside the heat exchange disc will flow back from the output pipe to the bottom of the reactor body, and thus circulate back and forth, thereby achieving a cooling effect on the pyrazolol.

[0014] Preferably, the adjusting assembly includes a rod slidably connected to the inner side wall of the mounting groove, the end of the rod is fixedly connected to an electromagnet, the end of the electromagnet is fixedly connected to a spring, the other end of the spring is fixedly connected to the inner side wall of the mounting groove, the side wall of the mounting groove is fixedly connected to an annular block, and the annular block is sleeved on the outer wall of the spring, and the outer wall of the rotating rod is located at the rod where a plug hole is opened. When it is necessary to collect pyrazolol, the electromagnet is closed, and the compression spring causes the rod to slide outward along the inner side wall of the mounting groove under the action of the compression spring, so that the end of the rod conflicts with the outer wall of the rotating rod. As the rotating rod rotates, when the plug hole and the rod coincide, the rod automatically enters the inside of the plug hole under the action of the compression spring, and the rotating rod drives the arc scraper to slide along the top of the fixed plate during the rotation of the rotating rod, so that the arc scraper can be used to push the pyrazolol to the top of the discharge port, thereby facilitating the collection of pyrazolol by the staff.

[0015] Preferably: an annular groove is provided on the inner wall of the reactor body at the arc scraper, and a slider is slidably connected to the inner wall of the annular groove. The end of the slider is fixedly connected to the end of the arc scraper away from the rotating rod. When the arc scraper rotates along the top of the fixed plate, the slider will rotate inside the annular groove, thereby increasing the stability of the arc scraper during rotation.

[0016] Preferably, the curvature direction of the arc-shaped scraper is consistent with the rotation direction of the motor, so that the curvature of the arc-shaped scraper can be used to push the pyrazolol to the top of the discharge port.

[0017] Preferably, the compressed length of the spring is much greater than the length of the socket, so as to prevent the insertion rod from not being able to separate from the socket when the electromagnet is turned on.

[0018] Preferably, the spring is in a compressed state when the electromagnet contacts the annular block. When the electromagnet is not working, the compression spring is used to automatically clamp the rod inside the machine socket, thereby allowing the arc scraper to quickly collect the pyrazolol.

Start the water pump 5 and the refrigeration element 10, and cool the water at the bottom of the reactor body 2 through the refrigeration element 10. Then use the water pump 5 to transfer the lower temperature water from the input pipe 4 to the inside of the heat exchange disc 6. The liquid inside the heat exchange disc 6 will flow back to the bottom of the reactor body 2 from the output pipe 7, and circulate back and forth, thereby achieving a cooling effect on pyrazolol.

[0027] like Figure 3 、 4 As shown in Figure 5, the top of the fixed plate 9 is slidably connected with an arc-shaped scraper 16, and the side wall of the arc-shaped scraper 16 is provided with a mounting groove 12.
