Technical Field

[0001] This utility model belongs to the field of wastewater and waste residue recycling technology, specifically relating to a device for recycling and reusing wastewater and waste residue from concrete mixing plants by compressing it into cakes. Background Technology

[0002] Waste residue from wastewater treatment needs to be dehydrated. The dehydrated waste residue can be used to mix building materials or in other fields, so it needs to be stored.

[0003] Currently, the traditional method for storing dewatered wastewater residue is to directly pile it up in designated indoor or outdoor areas, which occupies a lot of ground space, cannot make reasonable use of ground space, cannot be effectively integrated with other functional areas, and is not conducive to subsequent transportation.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0013] Preferably, the pressure plate has ear plates at both ends of its top.

[0014] A guide post is horizontally arranged above the compression box. The length direction of the guide post is consistent with the length direction of the compression box, so that the guide post passes through the ear plate and connects the ear plates of multiple pressure plates together.

[0015] Preferably, a spring is provided between two adjacent ear plates, and the spring is sleeved on the outside of the guide post.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0033] This embodiment aims to provide a device for recycling and reusing wastewater and slag from concrete mixing plants by compressing it into cakes. Its main function is to compress the dehydrated wastewater and slag into cakes for stacking in a designated area, saving ground space and facilitating transportation.

[0034] Reference Figure 1-3 The system includes a compression chamber 1 and pressure columns 4. The bottom of the compression chamber 1 is raised by four support columns 6, which are welded and fixed to the four corners of the bottom of the compression chamber 1 to provide space for material discharge. A discharge port 2 is provided on the bottom of the compression chamber 1 along its width (front-to-back direction). Four discharge ports 2 are evenly distributed along the length (left-to-right direction) of the compression chamber 1. A horizontally pull-out gate 3 is provided inside the discharge port 2. A wing plate 7 protrudes from the center of the side of the gate plate 3. A groove is provided on the inner side of the discharge port 2 along the length of the gate plate 3 to allow the wing plate 7 to slide smoothly. Plate 7 enters the chute and moves in a fixed direction. This wing plate 7 guides the gate plate 3 and also prevents the gate plate 3 from falling out of the discharge port 2. The pull-out end of the gate plate 3 is fixed with a handle. The pull-out ends of the four gate plates 3 are connected into one piece to form a pull-out frame, which makes it convenient for the staff to pull out the four gate plates 3 together. Alternatively, an electric telescopic rod can be set in the center of the bottom of the compression box 1, and the extension and retraction direction of the electric telescopic rod is consistent with the pull-out direction of the gate plate 3, so as to assist the staff in pulling out the gate plate 3. The electric telescopic rod is a common push-pull device on the market and is not shown in the figure.

[0035] Reference Figure 2-5 The pressure column 4 is rotatably placed inside the compression box 1 and placed horizontally. The length direction of the pressure column 4 is consistent with the width direction of the compression box 1. Five pressure columns 4 are evenly distributed along the length direction of the compression box 1, and the pressure column 4 is staggered with the material discharge port 2 below.

[0036] The transmission end of the pressure column 4, i.e. the front end, penetrates the wall of the compression box 1 and is fixedly fitted with a transmission sprocket 12. A bearing can be fixedly embedded at the connection between the pressure column 4 and the compression box 1, and the pressure column 4 and the bearing are fitted together to reduce its rotational resistance. The transmission sprockets 12 at the transmission ends of the five pressure columns 4 are synchronously driven by the sprocket group.

[0037] Specifically, the sprocket assembly includes a drive gear 14, a driven gear 15, and a chain 16. The drive gear 14 and driven gear 15 are rotatably mounted on the left and right sides of the front of the compression box 1, respectively. The chain 16 is driven between the drive gear 14 and the driven gear 15, so that the drive gear 14 drives the driven gear 15 to rotate. A motor 13 is connected to the front of the drive gear 14. The drive shaft of the motor 13 is fixed to the middle of the drive gear 14. The motor 13 is fixed to the support plate, and one end of the support plate is welded to the front of the compression box 1. The upper layer of the chain 16 is wavy, and the lower layer is horizontal, so that the upper layer of the chain 16 is meshed with the bottom and top of two adjacent drive sprockets 12, respectively. That is, starting from the left, the upper layer of the chain 16 is meshed with the bottom of the first drive chain 16, and with the top of the second drive chain 16, and so on. This method can enhance the meshing connection strength between the chain 16 and the drive sprocket 12, thereby ensuring the stability of the rotation of the pressure column 4.

[0038] Reference Figure 4 and Figure 5 A pair of pressure plates 5 are symmetrically arranged between each pair of adjacent pressure columns 4. The pressing space between the two pressure plates 5 corresponds exactly to the discharge port 2. The cross-section of the pressure column 4 is elliptical so that the two adjacent pressure columns 4 can squeeze the adjacent pressure plates 5 to reduce the distance between the two pressure plates 5 when they rotate from vertical to horizontal at the same time. Then, the sewage waste residue is compressed into a cake by reducing the distance between the two pressure plates 5. The distance between the two pressure plates 5 can be automatically restored to release the cake of sewage waste residue. The maximum distance between the two pressure plates 5 matches the size of the discharge port 2.

[0039] Specifically, ear plates 9 are welded to the top of both ends of the pressure plate 5. Guide columns 10 are horizontally arranged on the front and rear sides of the upper part of the compression box 1. Support blocks are welded and fixed to both ends of the guide columns 10, and the support blocks are welded and fixed to the top of the compression box 1. The length direction of the guide column 10 is consistent with the left and right length direction of the compression box 1, so that the guide column 10 passes through the ear plate 9. Then, the ear plates 9 on multiple pressure plates 5 are connected together through the guide column 10, so that the pressure plate 5 is displaced in a fixed direction. A spring 11 is provided between two adjacent ear plates 9. The spring 11 is sleeved on the outside of the guide column 10. The spring 11 can generate a certain counter-pushing force on the ear plate 9. With the help of this counter-pushing force, the pressure plate 5 can be reset to restore the distance between the two pressure plates 5 that are working together, thereby improving the flexibility of the pressure plate 5.

[0040] It is important to understand that there will always be a gap between two adjacent pressure plates 5, because even after the sewage and waste residue are compressed into cakes, they still need to occupy a certain amount of space.

[0041] In this embodiment, the tops of the two pressure plates 5 located between two adjacent pressure columns 4 are both extended obliquely upwards by a feeding plate 8. The two feeding plates 8 are in the shape of an inverted V to form an flared opening, and the feeding plates 8 at the tops of the two pressure plates 5 on both sides of the pressure column 4 are in contact with each other, so as to cover the pressure column 4 and prevent the wastewater and waste residue after dewatering from being accidentally put into the chamber where the pressure column 4 is located.

[0042] In actual use, the dewatered wastewater residue is first manually or by other conveying methods into the pressing space of two adjacent pressure plates 5. The height of the residue is reasonably controlled according to the actual pressing effect to prevent it from overflowing during the pressing process. Then, the motor 13 is started to drive the sprocket group to work. The upper chain 16 drives all the transmission sprockets 12 to rotate, which in turn drives all the pressure columns 4 to rotate synchronously. When two adjacent pressure columns 4 rotate, they will change from vertical to horizontal, thereby synchronously squeezing the two pressure plates 5 between the two adjacent pressure columns 4 to reduce their distance, and thus compressing the wastewater residue between the two pressure plates 5. Finally, the compressed wastewater residue is in the shape of a cake. All the residue cakes can be released by pulling the gate 3 out from the bottom of the compression box 1.

[0043] This embodiment can compress the dewatered wastewater residue into a cake shape for stacking, which greatly saves ground space and allows for effective integration with other functional areas. During subsequent transportation, the stacked waste residue cakes can be transferred together, which is extremely convenient.

[0044] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
