Description

Technical Field

[0001] This utility model relates to the field of sludge drying technology, and in particular to a sludge lifting and conveying device for dried sludge. Background Technology

[0002] Sludge drying, also known as sludge dewatering, refers to the process of removing most of the water content from sludge through processes such as filtration or evaporation. It generally involves using self-evaporation facilities such as sludge drying plants. After sludge concentration, physical methods are used to further reduce the water content, facilitating sludge transportation, stockpiling, utilization, or further treatment. An existing sludge drying lifting and conveying device (publication number CN 220131414 U) uses a servo cylinder to drive a pressing block when sludge volume control is needed. This block forces the discharge rail, which in turn presses the spring, causing the discharge rail to rotate and thus controlling the sludge conveying volume. However, this device only adjusts the elevation angle of the discharge rail to control the conveying volume, failing to guarantee the smoothness of sludge feeding and thus affecting conveying efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a dried sludge lifting and conveying device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A drying sludge lifting and conveying device includes a screw conveyor pipe body. A feeding cylinder is provided at the feed end of the screw conveyor pipe body. A feeding mechanism for controlling the feeding of dried sludge is provided inside the feeding cylinder. The feeding mechanism includes a fixed plate fixed inside the feeding cylinder. An mounting plate is provided at the upper end of the feeding cylinder. An agitating component for crushing the dried sludge inside the feeding cylinder is provided between the fixed plate and the mounting plate. Feeding holes are provided at intervals on the fixed plate. A feeding disc is provided on the lower side of the fixed plate. Dropping holes are provided at intervals on the feeding disc. A transmission component for driving the feeding disc to rotate is provided below the agitating component.

[0006] Further configuration: The agitation assembly includes an agitation shaft vertically mounted on a fixed plate and a mounting plate. There are two agitation shafts, and stirring blades are evenly distributed on the outer diameter of the agitation shaft. A geared motor is connected to the upper end of one of the agitation shafts.

[0007] With this setup, the agitator shaft is driven to rotate by a geared motor, causing the agitator blades on the shaft to rotate and break up the dried sludge.

[0008] Further configuration: The transmission assembly includes a gear fixed to the lower end of the agitator shaft, a central gear between the gears, a rotating shaft mounted on the central gear, the lower end of the rotating shaft being fixedly connected to the feeding disc, and a hollow cavity inside the fixing plate.

[0009] This configuration allows the central gear to transmit power to the rotating agitator shaft, which in turn drives the feeding disc to rotate, causing the crushed sludge in the feeding cylinder to fall intermittently.

[0010] Further configuration: The stirring shaft is rotatably connected to the fixed plate and the mounting plate, and the stirring blades are alternately arranged up and down on the stirring shaft.

[0011] With this configuration, the fixed plate and mounting plate provide rotational support for the stirring shaft, ensuring the stability of the rotation of the stirring blades on the stirring shaft.

[0012] Further configuration: The rotating shaft is rotatably connected to the mounting plate, and the central gear meshes with the gears to rotate.

[0013] This configuration allows the gear to drive the central gear to rotate, which in turn drives the shaft to rotate.

[0014] Further configuration: Arc-shaped baffles are provided on the fixed plate on both sides of the agitator shaft. The arc-shaped baffles are fixed to the inner wall of the feed cylinder. Scrapers are provided on the agitator shaft at the position where they are in contact with the fixed plate.

[0015] With this setup, the dried sludge in the feeding cylinder is concentrated into the feeding area by the arc-shaped baffle, and the scraper feeds and separates the sludge on the fixed plate when it rotates with the stirring shaft.

[0016] Further configuration: The feeding tray is rotatably connected to the fixed plate.

[0017] This configuration allows the material feeding holes on the feeding tray to alternately connect with the material feeding holes on the fixed plate for feeding.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] By setting up the feeding mechanism, the agitation component breaks up the dried sludge in the feeding cylinder. At the same time, the transmission component drives the feeding disc to rotate, so that the dropping hole on the feeding disc is continuously connected with the dropping hole on the fixed plate. This allows the broken sludge on the fixed plate to fall into the auger conveying pipe body below for lifting and conveying, which improves the smoothness of the dried sludge conveying control and ensures the conveying efficiency.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-4 As shown, a drying sludge lifting and conveying device includes a screw conveyor pipe body 1, a feeding cylinder 11 is provided at the feeding end of the screw conveyor pipe body 1, and a feeding mechanism for controlling the feeding of the drying sludge is provided inside the feeding cylinder 11.

[0031] In this embodiment: the feeding mechanism includes a fixed plate 21 fixed inside the feeding cylinder 11, an mounting plate 22 is provided at the upper end of the feeding cylinder 11, an agitation component for crushing the dried sludge inside the feeding cylinder 11 is provided between the fixed plate 21 and the mounting plate 22, feeding holes 201 are provided at intervals on the fixed plate 21, a feeding disc 210 is provided on the lower side of the fixed plate 21, a discharge hole 211 is provided on the feeding disc 210 at intervals, a transmission component for driving the feeding disc 210 to rotate is provided on the lower side of the agitation component, and the feeding disc 210 is rotatably connected to the fixed plate 21.

[0032] The agitation assembly includes an agitation shaft 23 vertically mounted on a fixed plate 21 and a mounting plate 22. Two agitation shafts 23 are provided, with stirring blades 24 evenly distributed along their outer diameter. One agitation shaft 23 is connected to a reduction motor 25 at its upper end. The agitation shaft 23 is rotatably connected to the fixed plate 21 and the mounting plate 22. The stirring blades 24 are alternately arranged vertically on the agitation shaft 23. Arc-shaped baffles 212 are provided on the fixed plate 21 on both sides of the agitation shaft 23. These baffles 212 are fixed to the inner wall of the discharge cylinder 11. A scraper 26 is provided on the agitation shaft 23 at a position where it contacts the fixed plate 21. When the scraper 26 rotates with the agitation shaft 23, it feeds and separates the sludge on the fixed plate 21. The reduction motor 25 drives the agitation shaft 23 to rotate, which in turn drives the other agitation shaft 23 to rotate via a transmission assembly. This causes the stirring blades 24 to alternately break up the dried sludge as they rotate, facilitating the passage of the sludge through the discharge hole 201.

[0033] The transmission assembly includes a gear 27 fixed to the lower end of the agitator 23, a central gear 29 disposed between the gears 27, a rotating shaft 28 mounted on the central gear 29, and the lower end of the rotating shaft 28 fixedly connected to the feeding disc 210. The fixed plate 21 has a hollow cavity inside, and the gears 27 and the central gear 29 are located in the hollow cavity of the fixed plate 21. The rotating shaft 28 is rotatably connected to the mounting plate 22, and the central gear 29 meshes with the gear 27 to rotate. Through the meshing rotation of the central gear 29 and the gear 27, the agitator 23 rotates, causing the feeding disc 210 at the lower end of the rotating shaft 28 to rotate. The discharge hole 211 on the feeding disc 210 is continuously connected with the discharge hole 201 on the fixed plate 21, allowing the crushed sludge on the fixed plate 21 to fall off.

[0034] The working principle and usage process of this utility model are as follows: The dried sludge is added into the feeding cylinder 11. The working motor 25 drives the stirring shaft 23 to rotate. The gear 27 at the lower end of the stirring shaft 23 is driven by the central gear 29 to drive the stirring shaft 23 at another location to rotate synchronously. The stirring blades 24 on the stirring shaft 23 break up the dried sludge. At the same time, when the central gear 29 rotates, it drives the feeding plate 210 at the lower end of the rotating shaft 28 to rotate. The broken up sludge on the fixed plate 21 is continuously connected to the feeding hole 201 through the dropping hole 211, so that the sludge falls into the lower auger conveying pipe body 1 for lifting and conveying.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
