Description

Technical Field

[0001] This invention relates to the field of sludge brick making technology, and in particular to a sludge brick making screening and grinding device. Background Technology

[0002] Currently, there are many methods for sludge treatment and disposal, including land application, landfilling, thermal treatment, and brick making. Among these, research on sludge resource utilization for brick making can, on the one hand, solve practical problems such as long dumping times, large dumping volumes, and high levels of disturbance in this project, eliminating ecological safety hazards at sludge dumping sites. On the other hand, it can effectively improve the efficiency of sludge disposal in brick factories, increase the amount of sludge disposed of, and effectively promote the comprehensive utilization of sludge in building materials.

[0003] Research on sludge resource utilization in brick-making processes can not only address the ecological pollution caused by sludge, but also utilize sludge as a partial substitute material in the production of sintered bricks, cement, and ceramsite, thus conserving resources. The production and utilization process achieves sludge reduction, harmlessness, and stabilization, largely avoiding secondary pollution. The comprehensive utilization of sludge in building materials is an important pathway for the sustainable development of sludge treatment, contributing to a balance of social, economic, and environmental benefits.

[0004] When making bricks from sludge, shale, fly ash and sludge need to be crushed and mixed. The output particle size of the mixed material needs to be within a certain specification, so a sludge brick making screening and grinding device is required.

[0005] Sludge brick-making screening and grinding equipment is generally composed of a grinding disc and a screening disc. The screening disc screens the ground particles, while the grinding disc grinds the larger particles.

[0006] In actual use, after the sludge mixture enters the sludge brick making screening and grinding device, due to the different particle sizes of the raw materials inside the sludge mixture, when the particle size difference is large, the larger particle size is easy to cause the screen holes of the screening and grinding device to be blocked, or to cause the grinding device to jam. The larger particle size is difficult to enter the grinding state and is difficult to grind and screen. Summary of the Invention

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1

[0039] Reference Figures 1 to 13 This is the first embodiment of the present invention, which provides a sludge brick-making screening and grinding device. This device can perform multi-stage screening of sludge mixtures with large particle size differences, avoiding clogging of the screening holes and jamming of the grinding disc. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 13As shown, it includes a grinding and screening mechanism 100, which includes a processing chamber 101 and a rotating member 102 that penetrates the processing chamber 101. A first spring 103 is sleeved on the outside of the rotating member 102. It also includes a grinding screen assembly 104 disposed on the rotating member 102. The grinding screen assembly 104 includes a middle grinding screen 104a fixedly disposed on the inner wall of the processing chamber 101, a lower grinding screen 104b fixedly disposed on the rotating member 102, and an upper grinding and screening member 104c slidably disposed on the rotating member 102. The first spring 103 provides downward pressure to the upper grinding and screening member 104c so that it adheres to the upper surface of the middle grinding screen 104a. In this embodiment, the processing chamber 101 consists of a hollow barrel and a material collection hood for guiding the material to slide down. The material collection hood has a conical structure, and the hollow barrel is disposed below the material collection hood. The two form a connected structure. The middle grinding screen 104a is fixed to the inner wall of the processing chamber 101. The inner wall of the hollow barrel, and above the collection hood, is equipped with a support frame to support the rotating component 102. The rotating component 102 can rotate, driving the upper grinding screen component 104c and the lower grinding screen 104b to rotate. At the same time, the upper grinding screen component 104c can slide outside the rotating component 102. The No. 1 spring 103 provides downward pressure to the upper grinding screen component 104c, keeping the upper grinding screen component 104c tending to fit into the middle grinding screen 104a. The upper grinding screen component 104c, the middle grinding screen 104a, and the lower grinding screen 104b are arranged inside the hollow barrel from top to bottom, and the central axes of the three are coincident. When screening and grinding sludge mixture, a step-by-step screening operation can be performed. Furthermore, the upper grinding screen component 104c is in a floating state, which can avoid jamming and clogging.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the rotating component 102 includes a drive motor mounted on the processing chamber 101 and a rotating shaft 102a mounted on the drive motor. The outer wall of the rotating shaft 102a is provided with a fixed disk 102b, and the rotating shaft 102a also includes an inclined groove 102c. In this embodiment, the drive motor is fixed by a support frame. The drive motor can drive the rotating shaft 102a to rotate. The rotating shaft 102a and the fixed disk 102b are fixedly connected. The bottom of the fixed disk 102b is in contact with the top of the first spring 103. The inclined groove 102c is in an inclined state.

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the upper grinding and screening component 104c includes an inclined block 104c-2 slidably disposed on the inclined groove 102c, and an upper grinding screen 104c-1 disposed on the inclined block 104c-2. In this embodiment, the outer wall of the inclined block 104c-2 and the inner wall of the inclined groove 102c are slidably connected. When a large sludge mixture enters between the upper grinding screen 104c-1 and the middle grinding screen 104a, the compression of the first spring 103 can cause the upper grinding screen 104c-1 to move between the two layers. The upper grinding screen 104c-1, in conjunction with the middle grinding screen 104a, first grinds larger particles, and then, through the elastic force of the first spring 103, it presses the upper grinding screen 104c-1 down to bring it closer to the middle grinding screen 104a. During this process, the movement of the upper grinding screen 104c-1 can cause the accumulated sludge mixture above to fall off, thus preventing blockage.

[0042] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 13 As shown, the upper grinding sieve 104c-1, the middle grinding sieve 104a, and the lower grinding sieve 104b are all provided with sieving holes and grinding blocks. The diameter of the sieving holes on the upper grinding sieve 104c-1, the middle grinding sieve 104a, and the lower grinding sieve 104b decreases progressively. The grinding blocks of the upper grinding sieve 104c-1 are located on the lower surface, the grinding blocks of the middle grinding sieve 104a are located on both the upper and lower surfaces, and the grinding blocks of the lower grinding sieve 104b are located on the upper surface. In this embodiment, The sludge mixture enters the upper grinding screen 104c-1 and the middle grinding screen 104a through the larger screening holes on the upper grinding screen 104c-1 for preliminary grinding. After grinding, the sludge mixture with particles of the correct diameter enters the middle grinding screen 104a and the lower grinding screen 104b through the screening holes on the middle grinding screen 104a for further grinding and crushing. Finally, the small particles formed fall through the screening holes on the lower grinding screen 104b, achieving multi-stage grinding and ensuring the discharge particle size of the sludge mixture.

[0043] In use, the drive motor drives the rotating shaft 102a to rotate, which in turn drives the lower grinding screen 104b and the upper grinding screen 104c-1 to rotate. The lower grinding screen 104b and the upper grinding screen 104c-1 work together with the middle grinding screen 104a fixed in the middle to perform multi-stage grinding and screening. During the grinding process, larger particles between the upper grinding screen 104c-1 and the middle grinding screen 104a will push the upper grinding screen 104c-1 upwards. The No. 1 spring 103 provides downward pressure to the upper grinding screen 104c-1, causing the larger sludge mixture inside to be crushed and screened. At the same time, the misalignment between the three grinding screens can help push the sludge mixture to fall into the next stage, avoiding blockage and jamming.

[0044] In summary, when grinding and screening sludge mixtures with large particle size differences, layered processing and multi-stage screening and grinding can be carried out to ensure the discharge particle size of the sludge mixture, while avoiding clogging of the screening holes and jamming of the grinding disc.

[0045] Example 2

[0046] Reference Figures 1-13 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a hammering mechanism 300 for the sludge brick-making screening and grinding device, which solves the problem of sludge mixture clogging on the upper grinding screen 104c-1. Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 12 As shown, it includes a limiting component 301 disposed on the processing chamber 101, and a locking lifting component 302 disposed on the limiting component 301, and a gravity hammer component 303 disposed on the locking lifting component 302. The rotating member 102 rotates and lifts the locking lifting component 302 to a certain height, and then releases the gravity hammer component 303 to strike downwards. The locking lifting component 302 includes a sliding load-bearing member 302a, and a pushing member 302b slidably disposed outside the sliding load-bearing member 302a. A sliding positioning element 302c is provided through 2b. In this embodiment, the limiting component 301 can limit the movement of the locking lifting component 302, so that the locking lifting component 302 can only slide vertically up and down, thereby allowing the gravity hammer component 303 to only rise and fall. When the gravity hammer component 303 falls, it hammers and crushes the sludge mixture accumulated on the upper grinding screen 104c-1, so that it can enter the screening hole on the upper grinding screen 104c-1 more smoothly.

[0047] Specifically, such as Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 and Figure 6 As shown, the rotating component 102 also includes a threaded groove 102e provided on the rotating shaft 102a. The threaded groove 102e is used to guide the positioning component 302c to move upward. In this embodiment, the threaded groove 102e is spiral in shape, and the part where its starting end and the end end are connected to the outer surface of the rotating shaft 102a is an arc surface, which facilitates guiding the positioning component 302c to slide out from the upper end of the threaded groove 102e, thereby allowing the positioning component 302c to disengage from the threaded groove 102e and allowing the gravity hammer assembly 303 to fall naturally.

[0048] Preferred, such as Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 12As shown, the sliding load-bearing component 302a includes a load-bearing frame 302a-1 and a positioning block 302a-2 disposed on the inner surface of the load-bearing frame 302a-1, and also includes a sliding groove 302a-3 disposed on the surface of the load-bearing frame 302a-1; the pushing component 302b includes a limiting frame 302b-1 slidably disposed on the load-bearing frame 302a-1, and a support barrel 302b-2 disposed on the limiting frame 302b-1, with a push plate 302b-3 slidably connected inside the support barrel 302b-2, and also includes a No. 3 spring 302b-4 disposed on the push plate 302b-3; the positioning component 302c includes a positioning block 302a-2 disposed on the push plate 302b-1. The slide bar 302c-1 on the slide bar 302c-1, and the positioning slider 302c-2 and the load-bearing block 302c-3 respectively provided at both ends of the slide bar 302c-1, also include the positioning groove 302c-4 provided on the load-bearing block 302c-3; the positioning slider 302c-2 and the threaded groove 102e are slidably connected. In this embodiment, the positioning slider 302c-2 is an inclined arc-shaped block, and the two sides of the side of the positioning slider 302c-2 that is in contact with the threaded groove 102e are rounded to facilitate the positioning slider 302c-2 sliding out from the top of the threaded groove 102e; in this embodiment, the lower surface of the positioning block 302a-2 After rounding the corners, when the positioning block 302a-2 and the positioning groove 302c-4 are close to being aligned, the rounded corners facilitate the sliding of the load-bearing block 302c-3, allowing the positioning block 302a-2 to insert into the positioning groove 302c-4. In this embodiment, the sliding groove 302a-3 and the slider 302c-1 are slidably connected, and the slider 302c-1 can slide up, down, left, and right inside the sliding groove 302a-3. The size of the load-bearing block 302c-3 is smaller than that of the load-bearing frame 302a-1. In this embodiment, one end of the slider 302c-1 passes through the support bucket 302b-2, and both... The sliding connection is used, and the push plate 302b-3 and the slide bar 302c-1 are fixedly connected. The No. 3 spring 302b-4 is sleeved on the outside of the slide bar 302c-1. The spring force of the No. 3 spring 302b-4 pushes the push plate 302b-3, so that the slide bar 302c-1 maintains the tendency to slide into the threaded groove 102e, ensuring that the positioning slider 302c-2 can be inserted into the inside of the threaded groove 102e. In this embodiment, the outer wall size of the load-bearing frame 302a-1 and the inner wall size of the limiting frame 302b-1 are matched, so that the load-bearing frame 302a-1 can only slide up and down inside the limiting frame 302b-1.

[0049] Furthermore, such as Figure 7As shown, the limiting component 301 includes a limiting post 301a disposed on the processing chamber 101 and a sliding block 301c slidably disposed on the limiting post 301a. The outer wall of the sliding block 301c is fixedly connected to the outer wall of the limiting frame 302b-1. In this embodiment, each limiting component 301 includes two limiting posts 301a. The limiting posts 301a are disposed below the support frame. The sliding block 301c can slide up and down the outer wall of the limiting post 301a. The movement of the limiting frame 302b-1 is limited by the fixed connection between the sliding block 301c and the limiting frame 302b-1.

[0050] Specifically, such as Figure 12 As shown, the gravity hammer assembly 303 includes a connecting rod 303a mounted on the load-bearing frame 302a-1, and a breaker hammer 303b mounted on the connecting rod 303a. It also includes a slot 303c opened at the bottom of the breaker hammer 303b. In this embodiment, the connecting rod 303a is fixedly mounted below the load-bearing frame 302a-1, and a plurality of slots 303c are evenly opened at the bottom of the breaker hammer 303b. The slots 303c can allow the sludge mixture to flow, and at the same time, when it falls, the slots 303c can block the particles being hit, reducing the occurrence of particle splashing.

[0051] Initially, due to the elastic force of spring 302b-4, the positioning slider 302c-2 is inserted into the threaded groove 102e. The rotation of the shaft 102a causes the threaded groove 102e to rotate, limiting the movement of the limiting frame 302b-1 via the limiting post 301a. Guided by the threaded groove 102e, the positioning slider 302c-2 rises. At this time, the positioning block 302a-2 and the positioning groove 302c-4 are misaligned. The positioning block 302a-2 contacts the upper surface of the load-bearing block 302c-3, supporting the load-bearing frame 302a-1, thereby lifting the breaker hammer 303b. After being lifted to a certain height, the positioning slider 302c-2 slides to the end of the threaded groove 102e. At this point, the positioning slider 302c-2 exits the threaded groove. When 102e slides out, it compresses the No. 3 spring 302b-4, causing the slide bar 302c-1 to slide and push the load-bearing block 302c-3 to slide. At this time, the positioning block 302a-2 and the positioning groove 302c-4 are aligned. Due to the gravity of the breaker hammer 303b pulling down the load-bearing frame 302a-1, the positioning block 302a-2 is inserted into the positioning groove 302c-4 and stuck. At the same time, because the positioning slider 302c-2 is disengaged from the threaded groove 102e, the breaker hammer 303b loses its support. At this time, the breaker hammer 303b falls under the action of gravity and hits the upper grinding screen 104c-1, crushing the sludge mixture particles above. At the same time, it promotes the sludge mixture to pass through the screening holes of the upper grinding screen 104c-1, avoiding accumulation and blockage, and improving the crushing effect of the sludge mixture.

[0052] Meanwhile, since the breaker hammer 303b falls above the upper grinding screen 104c-1, it can cause the upper grinding screen 104c-1 to slide down and deflect. At this time, the particles between the upper grinding screen 104c-1 and the middle grinding screen 104a can be crushed and squeezed out, further improving the grinding and anti-clogging effect.

[0053] In summary, this device facilitates the crushing of sludge mixtures located on the upper grinding screen 104c-1, increases the efficiency and effectiveness of screening and grinding, and avoids clogging.

[0054] It should be noted that, as Figure 7 , Figure 8 and Figure 10 As shown, the snap-fit ​​lifting assembly 302 also includes an abutment 302d disposed on the load-bearing frame 302a-1. The abutment 302d includes an arc-shaped pressure strip 302d-1 rotatably disposed on the load-bearing frame 302a-1, and a gravity handle 302d-2 disposed on the arc-shaped pressure strip 302d-1. In this embodiment, the arc-shaped pressure strip 302d-1 can rotate on the load-bearing frame 302a-1. Through the gravity of the gravity handle 302d-2, the arc-shaped pressure strip 302d-1 can be initially in a raised state.

[0055] Furthermore, such as Figure 10 As shown, the sliding load-bearing component 302a also includes an insertion groove 302a-4 provided on the load-bearing frame 302a-1. In this embodiment, after the arc-shaped pressure strip 302d-1 rotates at a certain angle, one end of it can pass through the insertion groove 302a-4 and abut against the load-bearing block 302c-3.

[0056] Furthermore, as shown in Figure 7, the limiting component 301 also includes a collar 301b disposed on the limiting post 301a and a blocking block 301d disposed on the collar 301b. In this embodiment, the inner surface diameter of the collar 301b and the outer surface diameter of the breaker hammer 303b are matched. The breaker hammer 303b and the collar 301b are coaxial. When the breaker hammer 303b descends or rises through the collar 301b, the sludge mixture around the breaker hammer 303b can be scraped off. In addition, after the breaker hammer 303b falls, the blocking block 301d will obstruct and push the gravity handle 302d-2 when the breaker hammer 303b is about to contact the upper grinding screen 104c-1, so that the arc-shaped pressure strip 302d-1 rotates and pushes down the load-bearing block 302c-3, so that the positioning block 302a-2 and the positioning groove 302c-4 are separated.

[0057] During operation, as the hydraulic breaker 303b descends, the positioning block 302a-2 and the positioning groove 302c-4 engage. After descending to a certain height, the blocking block 301d contacts the gravity handle 302d-2. The continued descent of the hydraulic breaker 303b causes the blocking block 301d to push the arc-shaped pressure bar 302d-1 to rotate until the arc-shaped pressure bar 302d-1 rotates through the insertion groove 302a-4 and pushes down the load-bearing block 302c-3, causing the positioning block 302a-2 and the positioning groove 302c-4 to engage. -4 disengages, at which point the elastic force of spring 302b-4 tends to push the positioning slider 302c-2 out, and the breaker 303b completes its descent and stops on the upper surface of the upper grinding screen 104c-1. The rotating shaft 102a continues to rotate, causing the threaded groove 102e to rotate. When the threaded groove 102e aligns with the positioning slider 302c-2 again, the elastic force of spring 302b-4 pushes the positioning slider 302c-2 into the threaded groove 102e, causing the two to engage, and then the cycle operation begins.

[0058] In addition, such as Figure 1 and Figure 2 As shown, the hammering mechanism 300 is provided in four groups and is distributed in a circumferential manner at equal intervals outside the rotating member 102. The initial height of the gravity hammer assembly 303 of each hammering mechanism 300 is different. In this embodiment, the gravity hammer assembly 303 will perform up and down hammering operations in sequence as the rotating member 102 rotates to perform uniform crushing. At the same time, each downward hammering of a single gravity hammer assembly 303 can improve the service life of the upper grinding screen 104c-1.

[0059] In summary, this device can efficiently break down, grind, and screen sludge mixtures.

[0060] Example 3

[0061] Reference Figures 1-13 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a beating mechanism 200 in the sludge brick-making screening and grinding device, which solves the problem of sludge mixture adhering to the lower surface of the lower grinding screen 104b. Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 11 As shown, it includes a fixing member 201 disposed in the processing chamber 101, and a sliding member 203 slidably disposed on the fixing member 201. A second spring 202 is sleeved on the outside of the sliding member 203, and a tapping arm 204 is also disposed on the sliding member 203. In this embodiment, the second spring 202 provides a pushing force to the sliding member 203, and the sliding member 203 can slide up and down inside the fixing member 201.

[0062] Preferred, such as Figure 5 and Figure 6 As shown, the rotating component 102 also includes a pushing groove 102d provided on the rotating shaft 102a. When the rotating shaft 102a rotates, the sliding component 203 is pushed to slide through the pushing groove 102d, and the spring force of the second spring 202 pushes the striking arm 204 to strike. In this embodiment, the pushing groove 102d can guide the sliding component 203 to slide down to a certain position, which facilitates the compression of the second spring 202. After compression, the second spring 202 can push the striking arm 204 to strike the lower surface of the lower grinding screen 104b above.

[0063] Specifically, such as Figure 5 and Figure 6 As shown, the pushing groove 102d includes a sliding surface 102d-1, a vertical surface 102d-2, and an annular surface 102d-3. The fixing member 201 includes a support ring 201a disposed in the processing chamber 101 and a limiting groove 201b formed on the support ring 201a. The sliding member 203 includes a limiting strip 203b slidably disposed on the limiting groove 201b. The limiting strip 203b is provided with a sliding sleeve 203a and also includes a sliding sleeve 203a disposed on the inner wall of the sliding sleeve 203a. In this embodiment, the protrusion 203c is slidably connected to the push groove 102d, the support ring 201a and the hollow barrel are fixedly connected, the sliding sleeve 203a is sleeved on the outside of the rotating shaft 102a, and the two can rotate and slide. The limiting strip 203b limits the movement of the sliding sleeve 203a, so that it can only slide up and down inside the support ring 201a. The inner wall of the support ring 201a and the outer wall of the sliding sleeve 203a are slidably connected.

[0064] In use, the elastic force of the second spring 202 keeps the sliding sleeve 203a pushing upward. When the rotating shaft 102a rotates, the lower sliding surface 102d-1 guides and pushes the protrusion 203c downward, causing the second spring 202 to compress. The sliding sleeve 203a and the striking arm 204 then slide down. When the protrusion 203c disengages from the lower sliding surface 102d-1, the presence of the vertical surface 102d-2 provides space for the protrusion 203c to slide upward. At this time, the force of the second spring 202 pushes the striking arm 204 upward, causing it to strike the lower surface of the lower grinding screen 104b. Simultaneously, in conjunction with the rotation of the lower grinding screen 104b, the sludge mixture on the lower surface of the lower grinding screen 104b is scraped off and discharged.

[0065] In summary, this facilitates the cleaning of the sludge mixture adhering to the lower surface of the lower grinding screen 104b, preventing clogging.

[0066] The process of this invention is as follows:

[0067] S1: Shale extraction: Shale is extracted using excavators and loaders, without blasting operations.

[0068] S2: Sludge aging: The sludge is first modified and solidified to reduce its moisture content to less than 40%, and then aged in two temporary storage workshops in rotation.

[0069] S3: Coarse crushing: Shale, fly ash and solidified sludge are crushed by hammer crusher and jaw crusher and then sent to sludge brick making screening and grinding device for grinding and screening. The output particle size is less than 3mm. After adding water and stirring, it is sent to the aging warehouse for aging for more than 3 days through a sealed belt conveyor to improve the plasticity of the mixture.

[0070] S4: The mixture of aged shale, fly ash and solidified sludge is mixed with water twice, and then the raw materials are mixed evenly using a twin-shaft vacuum extruder and a mixing extruder. It is then fed into a high-speed fine crusher and roller mill for fine crushing. The output particle size is less than 2mm. It is then shaped in a two-stage vacuum extruder, cut into strips and blanks, and then sent into the tunnel kiln by a shuttle car.

[0071] S5: The brick blanks are placed into the tunnel kiln for firing in the kiln car. Along the length of the tunnel kiln, it is divided into three parts: the preheating zone, the firing zone, and the cooling zone. The firing process is as follows:

[0072] First, the green bricks, dried to a certain moisture content in the drying chamber, are placed into the kiln. They are preheated in the preheating zone by combustion products (flue gas) from the firing zone before entering the firing zone, where they are fired to a specific temperature. At the kiln tail of the tunnel kiln, cold air is blown in to cool the fired products, forming a cooling zone. The blown-in cold air is heated as it flows through the products before being drawn back into the drying chamber as a heat source for drying the green bricks. This residual heat is used to preheat and dry the wet bricks inside the drying chamber, significantly reducing heat loss.
