Description

TECHNICAL FIELD

[0001] The utility model relates to sludge treatment and disposal technical field, concretely relates to a sludge slitting machine material distributing device. BACKGROUND

[0002] Municipal activated sludge is produced in the water treatment process in a sewage treatment plant; the sludge contains a large amount of nutrient components that can be utilized by plants, such as nitrogen, carbon, potassium, humus and trace elements such as zinc, copper and iron, and can be used as resources, but the sludge also contains a large amount of pathogenic bacteria, parasites (eggs), and heavy metals such as copper, aluminum, zinc, chromium, mercury and other non-degradable toxic and harmful substances such as polychlorinated biphenyls, dioxins and radioactive elements, if not effectively treated, the toxic and harmful substances in the sludge will pollute the soil and water, causing serious pollution and damage to the environment.

[0003] The existing treatment method of activated sludge generally includes conditioning, concentration, dewatering, drying and incineration, etc., in the sludge dewatering process, the activated sludge with high water content enters the sludge dewatering machine, and after dewatering, it is transported to the sludge slitting machine, and after cutting by the sludge slitting machine, it is dried; a material distributing device is needed between the sludge dewatering equipment and the sludge slitting machine, so that the sludge discharged from the sludge dewatering equipment can evenly cover the sludge slitting machine, ensuring efficient and stable operation of the sludge slitting machine; the traditional material distributing equipment uses a forward-reverse spiral conveyor for operation, so that the sludge falling into the material distributing device is dispersed to both sides, but in actual application, it is found that due to the high viscosity of the sludge, the sludge is easily bonded when the forward-reverse spiral conveyor is used, which affects the dispersion effect between the blades, and also easily agglomerates, which is not conducive to the stable operation of the equipment.

[0004] Therefore, the utility model technically reforms the traditional material distributing device, which can effectively avoid sludge bonding and agglomeration without affecting the dispersion effect, ensuring continuous and stable operation of the equipment and production. SUMMARY

[0005] The utility model aims at the deficiency of the prior art, and provides a sludge slitting machine material distributing device to prevent sludge bonding and plugging during material distribution.

[0006] To achieve the above object, the utility model adopts the following technical scheme: a sludge slitting machine material distributing device, including a material frame, the material frame is a cuboid, the material frame is provided with a feeding port above and a discharging port below, a rotating shaft is arranged in the material frame, the rotating shaft is provided with independent material distributing mechanisms arranged in a spiral shape, and the material distributing mechanisms on both sides of the rotating shaft are symmetrically arranged about the center of the material frame.

[0007] Furthermore, one end of the rotating shaft is connected to the side wall of the material frame, and the other end of the rotating shaft extends to the outside of the material frame and is connected to the motor reducer for transmission.

[0008] Furthermore, the material distribution mechanism includes a connecting rod, which is fixedly connected to the rotating shaft, and a material distribution plate is fixedly connected to the connecting rod.

[0009] Furthermore, the material distribution plate is arranged at an angle relative to the rotating shaft. When the rotating shaft rotates, the side of the material distribution plate closest to the center of the material frame first comes into contact with the sludge in the material frame.

[0010] Furthermore, the material distribution mechanism is evenly arranged on both sides of the material frame at intervals of 10 to 30 cm.

[0011] Furthermore, the thickness of the homogenizing plate is 3-5 mm.

[0012] Furthermore, a mounting bracket is fixedly installed on one side wall of the material frame, and a rotary resistance level gauge is installed through the mounting bracket.

[0013] The beneficial effects of this utility model are:

[0014] 1. During use, this utility model can evenly disperse the sludge falling from the sludge dewatering machine in the material frame, thereby facilitating the uniform and stable feeding of the sludge dryer below, which plays a positive role in ensuring continuous and stable production.

[0015] 2. The material distribution mechanisms of this utility model are spiral in shape but independently arranged. Therefore, during use, they can effectively prevent the adhesion of sludge materials. At the same time, the material distribution plate has a crushing function to prevent sludge from agglomerating, which plays a positive role in ensuring the stable operation of the equipment.

[0016] 3. This utility model uses a rotary resistance level gauge. On the one hand, the level gauge is used to control the material level in the material box, which helps to give full play to the crushing function of the material distribution plate. On the other hand, in actual production, the material box is located at a high position, which makes it inconvenient for operators to grasp the amount of material in the material box. The level gauge can monitor the material level in the material box in real time without climbing. It plays a positive and beneficial role in the stable operation of equipment and production, as well as the personal safety of operators. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0021] Embodiments of this utility model:

[0022] like Figure 1 As shown, in this embodiment, the material equalization device includes a material frame 2, which is a cuboid. The top and bottom surfaces of the material frame 2 are not closed. The top surface is the inlet 21, and the bottom surface is the outlet 22. The inlet 21 is connected to the sludge dewatering machine, and the outlet 22 is connected to the sludge cutting machine.

[0023] A motor reducer 1 is provided on one side of the material frame 2. The motor reducer 1 is connected to the rotating shaft 11, which is installed through the material frame 2.

[0024] A material distribution mechanism 3 is fixedly installed on the rotating shaft 11. The material distribution mechanism 3 includes a connecting rod 31, which is fixedly connected to the rotating shaft 11, and a material distribution plate 32 is fixedly connected to the connecting rod 31.

[0025] The material distribution plates 32 are symmetrically arranged on both sides of the material frame 2 with the center of the material frame 2 as the axis of symmetry. The discharge of the sludge dewatering machine falls into the material frame 2 from the middle part of the material frame 2. The material distribution plates 32 on each side are arranged in a spiral shape around the rotating shaft 11, but they are set independently of each other. The material distribution plates 32 on both sides of the material frame 2 are symmetrically arranged, with one rotating in the forward direction and the other in the reverse direction. When the motor reducer 1 is running normally, the material distribution plates 32 evenly scrape the material falling into the center of the material frame 2 to both sides of the material frame 2.

[0026] A mounting bracket 23 is installed on one side wall of the material frame 2, and a rotary resistance level gauge 4 is installed through the mounting bracket 23.

[0027] The principle of this utility model is as follows:

[0028] This invention distributes the sludge dewatering machine's output evenly through a material equalization mechanism 3, ensuring that the sludge material enters the sludge cutting machine below in a uniform and stable manner. This prevents the sludge from accumulating in the center of the material frame 2, which would affect the continuity and stability of production. After passing through the sludge cutting machine, the sludge is sent to the drying section and then incinerated for reuse, thus realizing the sludge treatment and disposal process.

[0029] In this utility model, the material falling into the sludge dewatering machine is evenly distributed to both sides of the material frame 2 by the material distribution mechanism 3. During the process, the material distribution mechanism 3 is spiral in shape as a whole, but there is a 10-30cm interval between each other and they are independent of each other. With the center of the material frame 2 as the central axis, the material distribution mechanisms 3 on both sides are symmetrically arranged about the central axis, with one rotating in a clockwise direction and the other in a counterclockwise direction, which can evenly distribute the falling sludge to both sides of the material frame 2.

[0030] A rotary resistance level gauge 4 is installed in the material frame 2. The rotary resistance level gauge 4 can measure the sludge level in the material frame 2. In actual production, the measurement data is transmitted to the on-site PLC. The on-site PLC controls the operating power of the sludge dryer to ensure that the material frame 2 has a suitable material level.

[0031] When the material level in the material frame 2 is at a suitable height, such as when the material level is between the rotating shaft 11 and the lowest point during the rotation of the material leveling mechanism 3, the material leveling plate 32 can also play a good crushing role, which can effectively prevent sludge from clumping and sticking. The thickness of the material leveling plate 32 is 3-5mm, which can effectively prevent blockage and ensure the continuous and stable operation of the equipment.
