Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a heat pump sludge low-temperature dehydrator for sewage treatment. Background Art

[0002] A heat pump sludge low-temperature dehydrator is a device used for sewage treatment, mainly for treating sludge. It adopts heat pump technology to remove the moisture in the sludge through the heating and dehydration processes, thereby reducing the volume and humidity of the sludge, and at the same time increasing the dry solid content rate of the sludge. The working principle of the heat pump sludge low-temperature dehydrator is to utilize the heat energy provided by the heat pump device to evaporate and remove the moisture in the sludge, thereby realizing the dehydration treatment of the sludge. Compared with traditional sludge dehydration methods, the heat pump sludge low-temperature dehydrator has the advantages of low energy consumption, high treatment efficiency, and simple operation. This kind of device is usually applied to sewage treatment plants, sludge treatment plants, and industrial wastewater treatment and other occasions to treat the high water content in the sludge, thereby reducing the volume and weight of the waste for subsequent disposal or resource utilization.

[0003] According to the patent number; CN218811309U, a new type of heat pump sludge low-temperature dehydrator is provided, including a main body device, a conveying component, and a feeding tank. A drying device is arranged inside the main body device. A feeding tank is arranged on the upper surface of the drying device. A conveying component is arranged on the inner wall of the drying device. A support frame is fixedly connected to the upper surface of the feeding tank. A crushing rotating tooth is movably connected to the inner wall of the feeding tank. In the utility model, when the sludge is transported by the conveying component and the moving block passes below the limiting block, after being squeezed by the limiting block, the vibration spring is compressed, so that the area of the first track where its top is located generates vibration, making the sludge suspended, increasing the heat exchange area, and accelerating the sludge drying efficiency. When the sludge is inside the feeding tank, the rotating motor drives the crushing rotating tooth to rotate to crush the sludge, making the connection gap of the sludge larger, facilitating the next step of work.

[0004] In the above, the treatment of the sludge dehydration operation is relatively simple. The heat exchange area is increased through drying to achieve the dehydration effect. However, in the actual use process, the operation time of this method is relatively long, and it is difficult to dehydrate the sludge in contact with the conveyor belt, and only the surface can be effectively dehydrated. Therefore, those skilled in the art provide a heat pump sludge low-temperature dehydrator for sewage treatment to solve the problems existing above. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art and propose a heat pump sludge low-temperature dehydrator for sewage treatment.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A heat pump sludge low-temperature dehydrator for sewage treatment, comprising a box body. In the middle left position at the top of the inner side wall of the box body, a mounting seat is installed. At the outer side position in the middle of the bottom of the mounting seat, a limiting sleeve is installed. At the middle position and the outer side position between the inner side walls of the limiting sleeve, limiting sliders are installed. The outer side wall of the limiting sleeve is slidably connected with a connecting sleeve. At the middle position near both sides of the inner side wall of the connecting sleeve, limiting sliding grooves are respectively opened. The two limiting sliders are respectively slidably connected at the middle positions of the inner side walls of the two limiting sliding grooves. At the middle position of the bottom of the connecting sleeve, a driven gear disc is installed. At the bottom of the driven gear disc, a dehydration tank is installed.

[0007] Further, the driving gear rotates and acts on the driven gear disc to rotate, causing the dehydration tank to rotate at a high speed. During the rotation process, the two limiting sliders are slidably connected in the two corresponding limiting sliding grooves, thereby ensuring the stability of the dehydration tank during rotation. Centrifugal force is generated by the high-speed rotation to throw the water liquid out of the sludge.

[0008] Further, the output end of the driving motor acts on the transmission shaft, causing the driving gear to rotate and acting on the driven gear to rotate.

[0009] Further, the separated water liquid is discharged through the drain pipe.

[0010] Further, the conveying mechanism drives the sludge to move reciprocally. Until the sludge is completely dehydrated, it is conveyed to the drainage plate by the conveying mechanism.

[0011] Further, the output ends of the heating device respectively act on each heating rod to generate heat.

[0012] Further, under the action of the sludge pump, the sludge to be dehydrated in the storage tank is extracted, conveyed through the feeding pipe to the feeding port, and then conveyed to the dehydration tank through the feeding port.

[0013] Further, a power distribution cabinet is installed on the right side wall of the box body.

[0014] Further, the output ends of the heating device respectively act on each heating rod to generate heat, and in cooperation with the fan and the air holes, the humid air inside the box body is quickly evaporated.

[0015] The present utility model has the following beneficial effects:

[0016] 1. In the utility model, the output end of the driving motor acts on the transmission shaft to rotate the driving gear, and acts on the driven gear to rotate, so that the dehydration tank is rotated at a high speed. During the rotation, the two limit sliders are slidably connected in the two corresponding limit slide grooves to ensure the stability of the dehydration tank during the rotation process. The centrifugal force is generated by high-speed rotation to throw the water out of the sludge and discharge it to the outside through the drain pipe, thereby improving the dehydration efficiency.

[0017] 2. In the utility model, the sludge after drying falls onto the conveying mechanism through the sludge valve. At this time, the output end of the heating device acts on each heating rod to generate heat, and cooperates with the fan and the air holes to quickly evaporate the humid air inside the box. The conveying mechanism drives the sludge to reciprocate and discharge it after drying. BRIEF DESCRIPTION OF THE DRAWINGS

At the middle position at the bottom of the connecting sleeve 21, a driven gear disc 16 is installed. At the bottom of the driven gear disc 16, a dehydration tank 26 is installed. The driving gear 15 rotates and acts on the driven gear disc 16 to rotate, so that the dehydration tank 26 rotates at a high speed. During the rotation process, the two limiting sliders 20 are slidably connected in the two corresponding limiting chutes 19, thereby ensuring the stability of the dehydration tank 26 during the rotation process. By generating centrifugal force through high-speed rotation, the water liquid is thrown out of the sludge.

[0026] At the middle and top position on the left side wall of the box body 1, a driving motor 13 is installed. The output end of the driving motor 13 is connected with a transmission shaft 14. The output end of the transmission shaft 14 penetrates through the middle and top position on the left side of the inner side wall of the box body 1. The output end of the transmission shaft 14 is connected with a driving gear 15. The driving gear 15 meshes with the driven gear disc 16. The output end of the driving motor acts on the transmission shaft, so that the driving gear rotates and acts on the driven gear to rotate.

[0027] At the middle and bottom position on the left side wall of the dehydration tank 26, a drain pipe is installed. The separated water liquid is discharged through the drain pipe. A conveying mechanism 22 is installed below the dehydration tank 26. At the middle and right position at the bottom of the inner side wall of the box body 1, a diversion plate 23 is installed. The conveying mechanism 22 drives the sludge to move back and forth. Until the sludge is completely dehydrated, it is conveyed to the diversion plate 23 through the conveying mechanism 22. At the middle and right position at the top of the inner side wall of the box body 1, a heating device 24 is installed. At the middle position at the bottom of the heating device 24, a number of heating rods 25 are arranged in an array. The output end of the heating device 24 acts on each heating rod 25 to generate heat respectively. At the middle and bottom position on the left side wall of the box body 1, a storage tank 5 is installed. At the middle and left position at the top of the storage tank 5, a feeding port 6 is opened.

[0029] Working principle: Under the action of the sludge pump 4, the sludge to be dehydrated in the storage tank 5 is extracted, transported through the feed pipe 3 into the feed port 2, and then transported through the feed port 2 into the dehydration tank 26. The output end of the drive motor 13 acts on the transmission shaft 14, causing the driving gear 15 to rotate, and then acting on the driven gear 16 to rotate, so that the dehydration tank 26 rotates at a high speed. During the rotation process, the two limit sliders 20 are slidably connected in the two corresponding limit chutes 19 to ensure the stability of the dehydration tank 26 during rotation. Through the centrifugal force generated by the high-speed rotation, the water liquid is thrown out of the sludge and discharged outward through the drain pipe. The dried sludge falls onto the conveying mechanism 22 through the sludge valve. At this time, the output end of the heating device 24 acts on each heating rod 25 to generate heat, and in cooperation with the blower 10 and the air holes 9, the humid air inside the box body 1 is quickly evaporated. The conveying mechanism 22 drives the sludge to move back and forth until the sludge is completely dehydrated, and then it is transported to the drainage plate 23 by the conveying mechanism 22, and is transported to the discharge port 8 under the action of the drainage plate 23, and finally collected in the discharge box 7.
