Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the sludge collection technical field, concretely relates to fluid power drive sludge collection device. BACKGROUND

[0002] In many fields such as sewage treatment, river dredging and industrial production, sludge treatment is always a key and challenging work. The traditional sludge collection and treatment method has many drawbacks, and innovative technology is needed to improve.

[0003] In the early stage, manual collection of sludge is a common means. Workers need to use simple tools to dig, shovel and operate in the sludge accumulation area. This method not only has very low efficiency, but also consumes a lot of manpower and time cost. Moreover, workers are exposed to harsh environments for a long time, which easily contacts harmful substances and seriously threatens their health. With the development of technology, mechanical collection equipment gradually appeared, but the early mechanical collection device mainly relies on electric drive, which has the problems of high energy consumption and high operation cost. In some remote areas or places with unstable power supply, the equipment cannot operate normally, which seriously limits its application range.

[0004] In the sludge conveying link, the traditional pipeline conveying method often causes pipeline blockage due to the high viscosity and particle characteristics of sludge, which needs frequent cleaning and maintenance, increasing the operation cost. Although some conveying equipment can realize sludge conveying, it lacks pretreatment function of sludge, and high water content of sludge brings great difficulty to subsequent treatment. For example, in sludge landfill, a large amount of water will occupy additional space, and may cause instability of landfill site foundation; in sludge incineration treatment, high water content means that more energy is needed to evaporate water, which reduces energy utilization efficiency.

[0005] For sludge temporary storage, the traditional temporary storage facility is usually a simple container, which lacks effective stirring and liquid level control mechanism. Sludge is easy to settle and harden during temporary storage, which affects subsequent use and treatment. Once the liquid level of the temporary storage container is too high, sludge overflow may occur, causing environmental pollution.

[0006] To solve the above series of problems, it is urgent to develop a device that is efficient, energy-saving, environmentally friendly and can realize integrated treatment of sludge collection, conveying and temporary storage. CONTENT OF THE UTILITY MODEL

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the technical scheme of the utility model has the following beneficial effects:

[0017] The water power pump under the driving of water flow can form a strong negative pressure at the inlet of the sludge collecting assembly, and the suction effect of the negative pressure can rapidly suck the sludge in a large area around into the collecting device. Compared with the traditional suction equipment driven by electricity, the sludge collecting range is wider, and the sludge collecting speed is faster, so that the sludge collecting efficiency is greatly improved, and a large amount of sludge can be collected in a short time, and the device is especially suitable for a scene where sludge is widely distributed and needs to be quickly cleaned. The water power pump is driven by external water flow, and the abundant water flow energy in nature is ingeniously converted into the power required for sludge collection, without additional consumption of a large amount of electric energy.

[0018] The sludge conveying assembly is inclined and arranged in cooperation with the spiral blades in the sludge conveying assembly, so that the sludge can be stably conveyed upwards, and the sludge can be preliminarily dewatered in the conveying process. The cooperation of the filter hole and the water storage cavity can separate the water in the sludge in time, and reduce the difficulty and cost of subsequent sludge treatment.

[0033] Refer to the attached Figs. 1-6 , fluid power driven sludge collecting device, including water power pump 1, water power pump 1's input end is connected with sludge collecting assembly 2, water power pump 1's output end is connected with sludge conveying assembly 3's input end, sludge conveying assembly 3's output end is connected with sludge temporary storage box 4, water power pump 1 drives turbine through external water flow, forms negative pressure at sludge collecting assembly 2 entrance, sludge is sucked to sludge conveying assembly 3, sludge conveying assembly 3 pushes sludge to sludge temporary storage box 4.

[0034] Sludge conveying assembly 3 includes support frame 31, support frame 31 is fixedly installed with mounting bracket 32, mounting bracket 32 is inclinedly provided with screw feeder 33, sludge inlet 34 of screw feeder 33 is connected with water power pump 1, sludge chute 39 of screw feeder 33 is connected with sludge temporary storage box 4, input shaft of screw feeder 33 is connected with motor one 35.Support frame 31 is provided with water storage cavity 36, water storage cavity 36 is arranged below screw feeder 33, water storage cavity 36 is provided with water outlet 37, and the lower end of the shell of screw feeder 33 is provided with filter hole 38.

[0035] Sludge temporary storage box 4 includes box body 41, the side of box body 41 is provided with overflow tank 42, overflow port 43 is arranged between box body 41 and overflow tank 42, and sludge outlet 47 is arranged at the lower end of box body 41 and overflow tank 42.Box body 41 upper end is fixedly installed with crossbeam 44, crossbeam 44 is rotatably installed with rotating shaft 45, the upper end of rotating shaft 45 is connected with motor two 48, and a plurality of stirring blades 46 are arranged on rotating shaft 45.

[0036] Working principle:

[0037] The external water flow impacts the turbine of the water power pump 1 at a certain flow rate and flow volume. The turbine can efficiently convert the kinetic energy of the water flow into its own rotational mechanical energy. With the high-speed rotation of the turbine, the flow channel structure inside the water power pump 1 causes the internal pressure to rapidly decrease, thereby forming a significant negative pressure environment at the inlet connected to the sludge collection assembly 2. Under the action of this negative pressure, the surrounding liquid containing sludge is quickly sucked up and continuously enters the sludge collection assembly 2, realizing the preliminary transfer of sludge from the surrounding environment to the collection device.

[0038] The sludge-water mixture sucked up by the sludge collection assembly 2 directly enters the screw feeder 33. The screw feeder 33 is installed in the inclined mounting frame 32, and the inclination angle is accurately calculated to ensure that the sludge moves smoothly upward under the push of the screw and to optimize the spatial layout of the overall device. After the motor 35 is started, its output shaft is stably connected to the input shaft of the screw feeder 33 through a shaft coupling, efficiently converting electrical energy into mechanical energy to drive the high-speed rotation of the screw blade. With the rotation of the screw blade, the sludge is pushed along the spiral trajectory, overcoming the force of gravity and its own viscous resistance, and gradually transported upward. During the transportation process, the lower end of the screw feeder 33 shell is uniformly distributed with filter holes 38, and the filter holes 38 are precisely designed to allow only water and other liquids to pass through, while sludge particles are intercepted. The filtered water falls into the water storage cavity 36 under the action of gravity. The structure design of the water storage cavity 36 can ensure the smooth convergence of the water flow. When the water level in the water storage cavity 36 reaches a certain height, the water can be discharged through the pre-set water outlet 37 under the action of gravity or a small pressure difference, completing the preliminary dewatering process of the sludge. Finally, the sludge that has undergone preliminary dewatering passes through the sludge chute 39 of the screw feeder 33 and smoothly slides into the sludge temporary storage box 4 relying on gravity and the residual power of the screw push.

[0039] After the sludge enters the box 41, the motor 48 starts to work. The motor 48 drives the rotating shaft 45 to rotate at high speed through the belt drive or direct coupling connection and the like. The rotating shaft 45 is uniformly installed with a plurality of stirring blades 46, and the shape, size and installation angle of the stirring blades 46 are optimized and designed. When the rotating shaft 45 rotates, the stirring blades 46 rotate at high speed in the box, constantly stirring and stirring the sludge. This stirring process can effectively break the agglomeration structure of the sludge, prevent the sludge from being deposited and hardened due to gravity, and maintain the fluidity and uniformity of the sludge. With the continuous entry of the sludge and the liquid into the box 41, when the liquid level in the box rises to the height of the overflow port 43, since the overflow port 43 is connected with the overflow box 42, and the liquid level of the overflow box 42 is relatively low, under the pressure formed by the liquid level difference, the liquid flows into the overflow box 42 through the overflow port 43. The existence of the overflow box 42 can effectively prevent the liquid from overflowing due to the high liquid level in the box 41, and can further carry out subsequent treatment such as sedimentation and separation of the liquid. When the temporarily stored sludge needs to be treated, the sludge can be discharged for subsequent disposal through the sludge outlet 47 at the lower end of the box 41 and the overflow box 42 by using gravity or external pumping equipment.

[0040] The above-described embodiments only express certain embodiments of the present application, and the description is relatively specific and detailed, but it should not be understood as limiting the scope of the present application; It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application; Therefore, the protection scope of the present application patent should be subject to the appended claims.
