Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, specifically to a quantitative flow-guiding insoluble sulfur dustproof feeding cylinder. Background Technology

[0002] Insoluble sulfur is a transparent, amorphous, chain-like elastic sulfur obtained by heating sulfur powder to boiling point (444.6 degrees Celsius) and then rapidly cooling it in cold water. In chemical production, insoluble sulfur is widely used as an important chemical raw material.

[0003] In the process of feeding insoluble sulfur, it is difficult to achieve precise quantitative control. It often requires manual operation based on experience. This not only leads to inaccurate feeding, affecting product quality and production efficiency, but also increases labor costs and operational difficulty. Utility Model Content

[0004] To address the problem of inaccurate feeding of insoluble sulfur in existing processes, which affects product quality and production efficiency, this invention provides a quantitative flow-guiding insoluble sulfur dustproof feeding cylinder with precise feeding volume.

[0005] This utility model provides the following technical solution: a quantitative flow-guiding insoluble sulfur dustproof feeding cylinder, comprising a flow-guiding mechanism, characterized in that: a dustproof mechanism is provided at the bottom of the flow-guiding mechanism; the flow-guiding mechanism includes an upper cylinder, a lower cylinder is provided at the bottom of the upper cylinder, a feed pipe is fixedly connected to the top of the upper cylinder, a feed frame is fixedly connected to the top of the feed pipe, a filter screen is fixedly connected to the inner wall of the feed frame, a cover plate is snapped onto the top of the feed frame, a conveying pipe is fixedly connected to the bottom of the lower cylinder, a butterfly valve is fixedly connected to the bottom of the conveying pipe, a connecting frame is fixedly connected to the left side of the butterfly valve, a motor is fixedly connected to the inner side of the connecting frame, an annular pressure sensor is fixedly connected to the right side of the butterfly valve, a flow-guiding frame is fixedly connected to the bottom of the butterfly valve, a discharge pipe is fixedly connected to the bottom of the flow-guiding frame, a first connecting ring is fixedly connected to the outer side of the lower cylinder, a first support rod is fixedly connected to the top of the first connecting ring, a second connecting ring is fixedly connected to the outer side of the upper cylinder, a second support rod is fixedly connected to the top of the second connecting ring, and a lifting plate is fixedly connected to the top of the second support rod.

[0006] Its further features are:

[0007] Flanges are provided at the bottom of the upper cylinder and the top of the lower cylinder, and the upper cylinder and the lower cylinder are fixedly connected by the flanges;

[0008] The motor output end is fixedly connected to the butterfly valve shaft, and a PLC controller is fixedly connected to the left side of the connecting frame. The motor and the ring pressure sensor are both electrically connected to the PLC controller.

[0009] The first support rod is provided in four parts, and the four first support rods are arranged in a circular array at the top of the first connecting ring. The surface of the hoisting plate has four hollowed-out mounting holes.

[0010] The bottom of the second connecting ring has four insertion holes that are adapted to the first support rods. The four ends of the first support rods away from the first connecting ring are respectively inserted into the four insertion holes at the bottom of the second connecting ring.

[0011] The dustproof mechanism includes a connecting sleeve, and a dustproof frame is fixedly connected to the bottom of the connecting sleeve;

[0012] The connecting sleeve is threaded with a fixing bolt on its outer side, and the connecting sleeve is fitted onto the outside of the discharge pipe and fixed by the fixing bolt.

[0013] With the above-described structure of this utility model, the quantitatively diverting insoluble sulfur dustproof feeding cylinder is hoisted to the designated installation position and fixedly installed using suitable hoisting equipment through the four hollowed-out mounting holes on the hoisting plate. Since the top of the first connecting ring on the outer side of the lower cylinder has four first support rods arranged in a circular array, and the bottom of the second connecting ring on the outer side of the upper cylinder has four insertion holes adapted to the first support rods, during installation, the ends of the first support rods furthest from the first connecting ring are respectively inserted into the insertion holes at the bottom of the second connecting ring. This structure constitutes the feeding cylinder. A stable support structure is provided to ensure secure installation. When feeding is required, the cover plate at the top of the feed frame is opened to prepare for adding insoluble sulfur into the feeding cylinder. The insoluble sulfur is poured into the feed frame, where a filter screen fixed to the inner wall of the feed frame will perform preliminary filtration, removing any larger impurities to prevent them from entering the feeding cylinder and affecting subsequent use and equipment operation. The filtered insoluble sulfur enters the upper cylinder through the feed pipe and then falls into the lower cylinder. Depending on actual production needs, the process is controlled via a motor and annular pressure transmission... The PLC controller, electrically connected to the sensors, is configured with the required feeding parameters and related control logic. When feeding is needed, the PLC controller starts the motor. Since the motor output is fixedly connected to the butterfly valve shaft, the motor drives the butterfly valve shaft to rotate, thereby opening the butterfly valve. This allows the insoluble sulfur in the lower cylinder to enter the butterfly valve through the conveying pipe, and then be discharged through the guide frame and discharge pipe. During the feeding process, the annular pressure sensor monitors the pressure change on the right side of the butterfly valve, i.e., the material discharge side, in real time. When the discharged insoluble sulfur reaches the set feeding amount, the pressure signal generated by the material on the annular pressure sensor is fed back to the PLC controller. The PLC controller controls the motor to stop rotating according to the preset program, thereby closing the butterfly valve and stopping the feeding, achieving the function of quantitative flow guidance. Through the combination of the motor, annular pressure sensor, and PLC controller, precise control of the feeding amount is achieved. The PLC controller can automatically control the start and stop of the motor according to preset parameters, thereby controlling the opening and closing of the butterfly valve, ensuring that the feeding amount is accurate each time, improving the automation level of the production process and the stability of product quality, and avoiding production problems caused by inaccurate feeding. The connecting sleeve of the dustproof mechanism is fitted onto the outside of the discharge pipe, and the connecting sleeve is fixedly connected to the discharge pipe by fixing bolts, so that the dustproof frame is located at a suitable position below the discharge pipe, which prepares for dust prevention in the subsequent feeding process. It can effectively prevent the dust generated during the feeding process from spreading to the surrounding environment, improve the working environment, reduce the harm to the health of operators, and also meet environmental protection requirements.

[0019] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A quantitative flow guiding insoluble sulfur dustproof feeding cylinder includes a flow guiding mechanism 1, and a dustproof mechanism 2 is provided at the bottom of the flow guiding mechanism 1.

[0020] The flow guiding mechanism 1 includes an upper cylinder 101, a lower cylinder 102 at the bottom of the upper cylinder 101, a feed pipe 103 fixedly connected to the top of the upper cylinder 101, a feed frame 104 fixedly connected to the top of the feed pipe 103, a filter screen 105 fixedly connected to the inner wall of the feed frame 104, a cover plate 106 snapped onto the top of the feed frame 104, a conveying pipe 107 fixedly connected to the bottom of the lower cylinder 102, a butterfly valve 108 fixedly connected to the bottom of the conveying pipe 107, a connecting frame 109 fixedly connected to the left side of the butterfly valve 108, and a connecting frame 109 fixedly connected to the inner side of the connecting frame 109. A ring pressure sensor 111 is fixedly connected to the right side of the motor 110 and the butterfly valve 108. A guide frame 112 is fixedly connected to the bottom of the butterfly valve 108. A discharge pipe 113 is fixedly connected to the bottom of the guide frame 112. A first connecting ring 114 is fixedly connected to the outside of the lower cylinder 102. A first support rod 115 is fixedly connected to the top of the first connecting ring 114. A second connecting ring 116 is fixedly connected to the outside of the upper cylinder 101. A second support rod 117 is fixedly connected to the top of the second connecting ring 116. A lifting plate 118 is fixedly connected to the top of the second support rod 117.

[0021] Flanges are provided at the bottom of the upper cylinder 101 and the top of the lower cylinder 102, and the upper cylinder 101 and the lower cylinder 102 are fixedly connected by the flanges.

[0022] Flange structures are provided at the bottom of the upper cylinder 101 and the top of the lower cylinder 102. A flange is a disc-shaped part, usually with multiple bolt holes, used to connect the two parts. When assembling the upper cylinder 101 and the lower cylinder 102, the flanges of the two are aligned, and then multiple bolts are passed through the corresponding bolt holes and tightened with nuts, thereby achieving a stable and fixed connection between the upper cylinder 101 and the lower cylinder 102. This flange connection method is not only convenient to install and disassemble, but also ensures the sealing and firmness of the connection, ensuring that the material is transported normally in the feeding cylinder without leakage or other problems.

[0023] The output end of motor 110 is fixedly connected to the valve shaft of butterfly valve 108. PLC controller 119 is fixedly connected to the left side of connecting frame 109. Motor 110 and ring pressure sensor 111 are both electrically connected to PLC controller 119.

[0024] The output end of motor 110 is fixedly connected to the valve shaft of butterfly valve 108 via a specific connection method, such as a coupling. Thus, when motor 110 starts and runs, the rotational motion of its output end can be directly transmitted to the valve shaft of butterfly valve 108, thereby driving the valve plate of butterfly valve 108 to open or close, achieving control of material conveying. A PLC controller 119 is fixedly installed on the left side of connecting frame 109. The PLC controller 119 is a programmable logic controller with powerful logic operation and control functions. Both motor 110 and ring pressure sensor 111 are... The ring pressure sensor 111 is electrically connected to the PLC controller 119 via wires. It can monitor the pressure of the material in the feeding cylinder in real time and convert the pressure signal into an electrical signal and transmit it to the PLC controller 119. The PLC controller 119 controls the motor 110 according to the received pressure signal and other preset parameters and logic programs. For example, when the material pressure reaches the set value, the PLC controller 119 will issue a command to control the motor 110 to stop running or adjust the running speed, thereby realizing quantitative control of material conveying and ensuring the accuracy and stability of the feeding process.

[0025] Four first support rods 115 are provided, and the four first support rods 115 are arranged in a circular array at the top of the first connecting ring 114. The surface of the hoisting plate 118 has four hollowed-out mounting holes.

[0026] There are a total of four first support rods 115. These four first support rods 115 are evenly arranged at the top of the first connecting ring 114 and distributed in a circular array. The circular array distribution means that the four first support rods 115 are distributed at equal angles around the center of the first connecting ring 114. This distribution method can ensure that the lower cylinder 102 is evenly stressed when supported, and improve the stability of the entire feeding cylinder. The surface of the lifting plate 118 has four hollow mounting holes. The position and size of these mounting holes are adapted to the top structure of the first support rods 115 and the connecting parts that may be used later. In practical applications, the lifting plate 118 can be fixedly connected to other equipment or structures by bolts or other connecting parts passing through these mounting holes, so as to facilitate the lifting, installation or fixing of the entire feeding cylinder in a specific position. The hollow mounting hole design can reduce the weight of the lifting plate 118 and meet the needs of connection and fixation.

[0027] The bottom of the second connecting ring 116 has four insertion holes that are adapted to the first support rod 115. The ends of the four first support rods 115 that are away from the first connecting ring 114 are respectively inserted into the four insertion holes at the bottom of the second connecting ring 116.

[0028] Four insertion holes are provided at the bottom of the second connecting ring 116. The positions of these four insertion holes correspond to the positions of the four first support rods 115 at the top of the first connecting ring 114. That is, the four insertion holes and the four first support rods 115 are spatially one-to-one. The ends of the four first support rods 115 away from the first connecting ring 114, i.e., the tops of the first support rods 115, are respectively inserted into the four corresponding insertion holes at the bottom of the second connecting ring 116. This insertion connection method is simple and convenient, and can quickly achieve the initial positioning and connection between the upper cylinder 101 and the lower cylinder 102. At the same time, the insertion connection also provides a basis for further fixing that may be carried out later, ensuring that the upper cylinder 101 and the lower cylinder 102 have sufficient stability and firmness after connection, and that there will be no shaking or separation during material conveying.

[0029] Using the four perforated mounting holes on the lifting plate 118, the quantitatively diverting insoluble sulfur dustproof feeding cylinder is hoisted to the designated installation position and fixedly installed using suitable hoisting equipment. Since the top of the first connecting ring 114 on the outer side of the lower cylinder 102 is fixed with four first support rods 115 arranged in a circular array, and the bottom of the second connecting ring 116 on the outer side of the upper cylinder 101 has four insertion holes adapted to the first support rods 115, during installation, the ends of the first support rods 115 furthest from the first connecting ring 114 are respectively inserted into the insertion holes at the bottom of the second connecting ring 116. This structure provides a stable support structure for the feeding cylinder, ensuring its secure installation. When feeding is required, the cylinder is... The cover plate 106, which is snapped onto the top of the feed frame 104, is opened to prepare for adding insoluble sulfur into the feeding cylinder. The insoluble sulfur is poured into the feed frame 104. The filter screen 105 fixed to the inner wall of the feed frame 104 will perform preliminary filtration of the poured insoluble sulfur, removing any potentially large impurities to prevent them from entering the feeding cylinder and affecting subsequent use and equipment operation. The filtered insoluble sulfur enters the upper cylinder 101 through the feed pipe 103 and then falls into the lower cylinder 102. Based on actual production needs, the internal wiring connections of the motor 110, the annular pressure sensor 111, and the PLC controller 119 are all existing technologies and will not be elaborated further here. (The last sentence appears to be incomplete and possibly refers to a technical detail about the connection between the motor 110 and the PLC controller 119.) The PLC controller 119, electrically connected to both the annular pressure sensor 111 and the PLC controller 119, is configured with the required feeding parameters and related control logic. When feeding is required, the PLC controller 119 controls the motor 110 to start. Since the output of the motor 110 is fixedly connected to the valve shaft of the butterfly valve 108, the motor 110 drives the valve shaft of the butterfly valve 108 to rotate, thereby opening the butterfly valve 108. This allows the insoluble sulfur in the lower cylinder 102 to enter the butterfly valve 108 through the conveying pipe 107, and then be discharged through the guide frame 112 and the discharge pipe 113. During the feeding process, the annular pressure sensor 111 monitors the pressure change on the right side of the butterfly valve 108, i.e., the material discharge side, in real time. When the discharged insoluble sulfur reaches the set feeding level... During material feeding, the pressure signal generated by the annular pressure sensor 111 is fed back to the PLC controller 119. The PLC controller 119 controls the motor 110 to stop rotating according to the preset program, thereby closing the butterfly valve 108 and stopping the feeding, thus realizing the function of quantitative flow guidance. Through the combination of the motor 110, the annular pressure sensor 111 and the PLC controller 119, precise control of the feeding amount is achieved. The PLC controller 119 can automatically control the start and stop of the motor 110 according to the preset parameters, thereby controlling the opening and closing of the butterfly valve 108, ensuring that the feeding amount is accurate each time, improving the automation level of the production process and the stability of product quality, and avoiding production problems caused by inaccurate feeding amount.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4The dustproof mechanism 2 includes a connecting sleeve 201, and a dustproof frame 202 is fixedly connected to the bottom of the connecting sleeve 201.

[0031] The connecting sleeve 201 is threaded with a fixing bolt on the outside. The connecting sleeve 201 is sleeved on the outside of the discharge pipe 113 and fixed by the fixing bolt.

[0032] A fixing bolt is provided on the outer side of the connecting sleeve 201. The fixing bolt is installed on the connecting sleeve 201 by means of threaded connection. A threaded hole matching the thread of the fixing bolt is opened at the corresponding position on the outer side of the connecting sleeve 201. When installing the dustproof mechanism 2, firstly, the connecting sleeve 201 is placed on the outside of the discharge pipe 113 of the feeding cylinder. Then, by rotating the fixing bolt, the end of the fixing bolt is gradually moved closer to the outer wall of the discharge pipe 113 until the end of the fixing bolt is tightly pressed against the outer wall of the discharge pipe 113. In this way, the friction between the fixing bolt and the outer wall of the discharge pipe 113 is used to firmly fix the connecting sleeve 201 on the outside of the discharge pipe 113, thereby ensuring that the entire dustproof mechanism 2 is stably installed on the feeding cylinder and will not loosen or fall off during the material conveying process, thus ensuring the normal functioning of the dustproof function.

[0033] The connecting sleeve 201 of the dustproof mechanism 2 is fitted onto the outside of the discharge pipe 113, and the connecting sleeve 201 is fixedly connected to the discharge pipe 113 by fixing bolts, so that the dustproof frame 202 is located at a suitable position below the discharge pipe 113, which prepares for dust prevention in the subsequent feeding process. It can effectively prevent the dust generated during the feeding process from spreading to the surrounding environment, improve the working environment, reduce the harm to the health of operators, and also meet environmental protection requirements.
