Abstract
Description
Technical Field
[0001] The utility model relates to a shipboard food waste crusher, in particular to a feeding safety and water accompanying structure of the crusher. Background Art
[0002] Ships sway to varying degrees, so shipboard food waste pulverizers have higher safety requirements than land-based pulverizers. In order to prevent the shaking of the ship and the instability of the hands or tools when operating the equipment, causing personal injury or equipment damage, the usual measure is to add a cover plate above the hopper of the pulverizer. When feeding is required, the cover plate is opened for feeding, and the motor is required not to run at this time. The pulverizing motor can only run when the cover plate is closed after feeding. The above control requirements can be achieved by electrically interlocking the cover plate with the limit switch.
[0003] However, compared with land-based food waste shredders, ship-based food waste shredders generally have the following problems because they use safety interlock covers: first, feeding is intermittent rather than continuous, the processing volume is small, and the production efficiency is low; second, the feeding is uneven, which can easily cause material accumulation in the hopper or equipment overload; third, the motor is started frequently, which can easily cause heat and affect its service life. Summary of the invention
[0004] The utility model aims to overcome the defects in the prior art and provide a feeding safety and water accompanying structure for a pulverizer which is small in size, compact in structure and easy to install and use.
[0005] The utility model is implemented as follows: a feed safety and water accompanying structure of a pulverizer, comprising a shaft group and a secondary bucket plate arranged at the feed port of the pulverizer, the shaft group comprising a pipe shaft, a first sleeve, a first pressure cover, a ferrule joint, a second sleeve, a second pressure cover and a sealing plate, the first sleeve is sleeved on one end of the pipe shaft, one end of the first pressure cover and one end of the first sleeve are mutually nested and connected, and the other end of the first pressure cover and one end of the ferrule joint are mutually nested and connected; the second sleeve is sleeved on the other end of the pipe shaft, one end of the second pressure cover and one end of the second sleeve are mutually nested and connected; the sealing plate fixes and closes the other end of the pipe shaft, and a plurality of spray water holes are provided on the pipe shaft; the secondary bucket plate is fixed on one side of the pipe shaft and is located below the spray water holes.
[0006] A first sealing ring is provided between the first shaft sleeve and the first gland; and a second sealing ring is provided between the second shaft sleeve and the second gland.
[0007] The first sealing ring and the second sealing ring are lip sealing rings respectively.
[0008] The cross-sectional shape of the spray water hole is rectangular, and a plurality of the spray water holes are arranged in a step-by-step manner along the axial direction of the tube axis.
[0009] The outer diameter of the tube shaft is 9.5-10.5 mm.
[0010] The ferrule joint comprises a tube shaft interface and a water inlet interface which are connected to each other. The tube shaft interface is connected to the tube shaft. The axis of the tube shaft interface and the axis of the water inlet interface are perpendicular to each other to form a 90-degree ferrule joint.
[0011] The auxiliary bucket plate is inclined downward relative to the feed opening.
[0012] The beneficial effects of the utility model are as follows: the auxiliary bucket plate is tilted downward relative to the feed port of the crusher, and the auxiliary bucket plate can cover most of the feed port without affecting normal feeding, and can prevent hands or tools from entering the crushing bin, and can rotate with the pipe axis. After the work is completed, the auxiliary bucket plate can be lifted for washing and cleaning, so as to achieve continuous feeding and safe operation.
[0013] The shaft group is used to solve the feeding problem. Water enters from the pipe shaft through the ferrule joint. At the same time, the spray water line is parallel to the guide plate, which just brings the material into the crushing bin to solve the accompanying water during the feeding process of the equipment and facilitate feeding and crushing.
[0014] The first shaft sleeve and the second shaft sleeve are positioned by the ferrule joint, the first gland and the second gland, and the waterway is sealed by the first sealing ring and the second sealing ring. The shaft assembly of the utility model has a small size, a simple structure, reliable sealing and low resistance.
[0015] The utility model solves the problem of continuous feeding and accompanying water of a shipboard food waste crusher, is particularly suitable for application in places with limited space, and achieves safety, high efficiency and reliable operation. BRIEF DESCRIPTION OF THE DRAWINGS
