Abstract
Description
Technical Field
[0001] The utility model relates to a delivery and feeding equipment structure, in particular to a delivery head structure for powdery materials. Background Art
[0002] Compared with the traditional powder bag transportation, bulk transportation of powder materials can reduce the packaging, stacking, loading, transportation, unloading, unpacking and other links of powder materials, which not only saves the equipment configuration, personnel input and storage site investment of each link, but also eliminates the pollution of powder materials to the environment and the pollution of the environment to powder materials during the circulation process. At present, there are usually three ways to transport powder materials in bulk: the first is pneumatic conveying, which is to use airflow to transport powder materials through pipelines; one is mechanical conveying, which is to transport powder materials through mechanical equipment such as belt conveyors; and the other is tank truck transportation, which loads powder materials into special tank trucks and then transports them to the place of use. However, the first two transportation methods are usually suitable for short-distance transportation, while long-distance transportation is carried out by tank trucks.
[0003] A lifting delivery head is provided at the bottom of the silo, a control valve is installed on the delivery head, and a conical material distribution plate is provided below the delivery head. The delivery head and the conical material distribution plate are fixedly connected by a connector. The function of the conical material distribution plate is to guide the powdered material to disperse around after it comes out of the delivery head, so as to avoid direct accumulation under the delivery head and cause blockage. A loading pipe is vertically provided on the top of the tanker's loading tank, and a valve is installed on the loading pipe. When loading, the tanker driver cannot see the position between the delivery head and the loading pipe. Therefore, it is necessary for the on-site staff to operate the vehicle by observing and directing the driver under the command of the on-site staff to align the loading pipe with the delivery head. When the vehicle moves so that the loading pipe is located below the delivery head, the delivery head begins to descend, so that the lower part of the delivery head extends into the loading pipe, and at the same time, the conical material distribution plate enters the loading tank. Although there are instructions from on-site workers, since the conical dividing plate is located below the delivery head, during the descent of the delivery head, the conical dividing plate will first enter the loading pipe. As the delivery head continues to descend, after the conical dividing plate enters the loading pipe to a certain depth, the sight of the staff outside will be blocked by the loading pipe, and they will not be able to observe the position of the conical dividing plate. If there is a certain offset between the delivery head and the loading pipe, the conical dividing plate will easily abut against the inner wall of the loading pipe, thereby affecting the descent of the delivery head and, in severe cases, causing deformation and damage to the conical dividing plate. Utility Model Content
[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is: how to provide a powder material shipping head structure that is convenient for docking and unloading with a tank truck loading pipe, can avoid damage to the conical dividing plate during the docking process, and improve the docking quality.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A delivery head structure for powdered materials comprises a downwardly arranged conical delivery head, the bottom of the conical delivery head is a delivery port, a conical distribution plate which is coaxial with the conical delivery head and arranged upward is arranged below the conical delivery head, a guide rod which is coaxial with the conical delivery head is arranged inside the conical delivery head, the lower end of the guide rod protrudes out of the delivery port, the rod body of the guide rod located inside the conical delivery head is fixedly connected to the delivery head through a fixing frame, the lower end of the guide rod passes through the conical distribution plate and protrudes below the conical distribution plate, the conical distribution plate can slide and cooperate with the guide rod along the direction of the guide rod center line, the maximum diameter of the conical distribution plate is larger than the diameter of the delivery port, and the guide rod is provided with a conical distribution plate. A limit block for limiting the position of the conical material distribution plate is arranged on the rod body and below the conical material distribution plate, and a detection sensor for detecting the conical material distribution plate abutting against the limit block is installed on the limit block. When the conical material distribution plate abuts against the limit block, the conical material distribution plate is spaced apart from the delivery port, and a lifting rope is fixedly connected to the top of the conical material distribution plate. The fixing position of the lifting rope and the conical material distribution plate is located within the projection of the delivery port along the vertical direction. The lifting rope passes through the delivery port and extends above the conical delivery head. The conical material distribution plate can be pulled upward by the lifting rope, so that the conical material distribution plate can close the delivery port.
[0007] In the utility model, the lifting and lowering control of the conical material dividing plate can be realized by controlling the pulling of the lifting rope. After the tank truck reaches the corresponding position under the command of the on-site staff, the descent of the delivery head can be controlled. Since the conical material dividing plate is currently abutted against the delivery port, the position of the conical material dividing plate can be temporarily ignored, and only the position between the delivery head and the tank truck loading pipe can be considered to meet the docking of the delivery head and the loading pipe. After the delivery head is docked in place, the control of the lifting rope is released, so that the conical material dividing plate will descend under the action of its own gravity, and then the delivery port will be opened. At this time, if the position of the shipping head deviates, the conical dividing plate will interfere with the inner wall of the loading tube during its descent. Since the conical dividing plate descends naturally under gravity without external force, it will automatically stop descending after it abuts against the loading tube, and will not cause damage to the conical dividing plate. In addition, after the interference occurs, the conical dividing plate cannot be abutted against the limit block, that is, the cover on the shipping port cannot be fully opened. In this way, the detection sensor cannot detect the conical dividing plate and cannot receive a signal, which means that the shipping head is not correctly docked with the loading tube. At this time, the shipping head needs to be lifted and docked again until it is detected that the conical dividing plate abuts against the limit block, indicating that the docking position of the shipping head and the loading tube is accurate and there is no obstacle to shipping, so that shipping can be carried out smoothly.
[0008] As an optimization, the detection sensor is a reed sensor, which is connected in series in the detection circuit. A magnet is installed on the inner top surface of the conical material distribution plate and at the position corresponding to the reed sensor. When the conical material distribution plate abuts against the limit block, the reed sensor can sense the magnetic field of the magnet and connect the detection circuit. The reed sensor can detect the magnetic field of the magnet. After the conical material distribution plate abuts against the limit block, the magnetic field of the magnet affects the metal sheet inside the reed sensor, so that the metal sheet and the internal circuit of the sensor are closed, so that the detection circuit is connected; if the conical material distribution plate does not abut against the limit block, the magnet has little effect on the reed sensor, and the metal sheet inside it will not change. At this time, the circuit is disconnected, so the position of the conical material distribution plate can be judged by connecting and disconnecting the detection circuit.
[0009] As an optimization, the limit stop is a columnar structure that is integrally formed with the guide rod and arranged on the same center line. The diameter of the limit stop is larger than the diameter of the guide rod. The reed sensor is embedded in the top of the limit stop. The inner top surface of the conical material distribution disk protrudes downward along the center line direction of the conical material distribution disk to form a mounting boss. The mounting boss is provided with a sliding hole along the center line direction for the guide rod to pass through. The magnet is a circular ring structure and is sleeved on the guide rod and spaced apart from the guide rod. The magnet is fixedly connected to the bottom of the mounting boss.
[0010] As an optimization, a telescopic sealing sleeve is provided on the guide rod and between the mounting boss and the limit stopper, and the two ends of the telescopic sealing sleeve are respectively fixedly and sealedly connected to the mounting boss and the limit stopper, and the magnet and the reed sensor are both located in the sealed space of the telescopic sealing sleeve, and the telescopic amount of the telescopic sealing sleeve along the center line direction of the guide rod is greater than the distance when the conical material distribution plate abuts against the conical delivery head and the limit stopper respectively. During the lifting and lowering process of the conical material distribution plate, the telescopic sealing sleeve can be extended and compressed accordingly to protect the reed sensor inside it and prevent dust from affecting its service life.
[0011] As an optimization, the fixing frame includes a connecting tube arranged with the same center line as the conical delivery head, and a plurality of connecting rods extending radially along the connecting tube are evenly spaced and fixed on the circumference of the connecting tube around the center line direction of the connecting tube, and a connecting boss is formed on the inner wall of the conical delivery head at a position corresponding to the end of the connecting rod, and the connecting rod is fixedly connected to the corresponding connecting boss by a connecting bolt, and a fixing screw is formed on the upper end of the guide rod along the center line direction thereof, and the fixing screw passes through the inner hole of the connecting tube and can slide with the connecting tube along the center line direction, and a fixing bolt is threaded on the rod body of the fixing screw located above the connecting tube, and the fixing bolt and the guide rod are respectively pressed against the two ends of the connecting tube to be fixedly connected together. It is convenient for installation and disassembly.
[0012] As an optimization, a silo is provided above the conical delivery head, a discharge port is provided at the lower end of the silo, the top of the conical delivery head is a feed port, a connecting cloth bag is provided between the silo and the conical delivery head, and the two ends of the connecting cloth bag are respectively connected with the discharge port of the silo and the feed port of the conical delivery head. The delivery head will remain in a drooping state under the action of its own gravity, and when the conical dividing plate is lifted by the pulling rope, the conical dividing plate will first abut against the delivery head, and as the pulling rope continues to be lifted, the conical dividing plate can drive the delivery head to rise together; after the delivery head rises, when the pulling rope is lowered, under the action of gravity, the delivery head will be placed on the conical dividing plate and descend with the conical dividing plate, and the delivery head will stop descending only after reaching the length limit of the connecting cloth bag, at which time the conical dividing plate can continue to descend to realize the opening of the delivery port. In this way, the lifting and lowering control of the delivery head can be realized at the same time by controlling the conical dividing plate, without having to set up a separate lifting device for the delivery head, thereby reducing costs.
[0013] Compared with the prior art, the utility model has a simple structure and is easy and reliable to use. It can avoid damage to the conical dividing plate during the docking process of the shipping head with the tank truck loading pipe. At the same time, it can judge the accuracy of the docking position between the shipping head and the tank truck loading pipe by detecting the position of the conical dividing plate, thereby improving the shipping quality.
