Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and in particular to a Z-type conveyor and sludge conveying system for conveying sludge. Background Technology
[0002] Currently, sludge conveying equipment generally uses screw conveyors and submerged scraper conveyors. Screw conveyors are generally used for horizontal or inclined sludge conveying at a small angle, suitable for places with small height differences. Submerged scraper conveyors are used for inclined sludge conveying in places with large height differences or confined spaces. Submerged scraper conveyors are transportation equipment that uses a scraper chain moving within a closed shell to transport bulk sludge to a predetermined target. It continuously transports bulk sludge within a closed rectangular cross-section shell using a scraper chain. Due to its simple structure, flexible process layout, and small footprint, and because the shell is sealed, it can transport toxic, easily airborne, or odorous sludge, ensuring a good environment.
[0003] However, due to the limitations of the sludge itself and the problems of low sludge output and easy material accumulation in the buried scraper conveyor method, the following aspects are specifically manifested: First, in the existing conveying method, the scraper conveyor restricts the chain swing and the formation of conveying space in the vertical conveying chain. The addition of partitions inside the box reduces the internal space of the shell. Because the sludge is sticky, after a period of conveying, the sludge is easy to form sludge on the vertical conveying surface near the shell. Second, sticky sludge is not only easy to sludge on the shell, but also easy to accumulate on the surface of the conveying plate. Utility Model Content

[0020] The conveying drive component is installed inside the housing;
[0021] The drive roller is mounted on the output end of the conveying drive component, and the drive roller is connected to both of the two conveying chain groups in a driving connection.
[0022] Two conveyor chain groups are arranged in parallel; each conveyor chain group includes an outer chain and an inner chain; the outer chain includes an outer Z-shaped conveyor chain and an outer Z-shaped rotary chain, which are connected end-to-end; the inner chain includes an inner Z-shaped conveyor chain and an inner Z-shaped rotary chain, which are connected end-to-end; the horizontal conveying sections of the outer Z-shaped conveyor chain and the inner Z-shaped conveyor chain are arranged in parallel; the vertical lifting sections of the outer Z-shaped conveyor chain and the inner Z-shaped conveyor chain are arranged in parallel.
[0023] Multiple driven rollers are respectively and driveably located at the bends of the outer Z-shaped conveyor chain, the outer Z-shaped rotary chain, the inner Z-shaped conveyor chain, and the inner Z-shaped rotary chain.

[0031] This embodiment provides a Z-type conveyor and sludge conveying system for conveying sludge, including a housing, a Z-type conveyor body and a vibration mechanism installed inside the housing; firstly, because the surface of the conveyor plate used to support the sludge remains horizontal during the conveying process from the inlet to the outlet, the sludge entering from the inlet remains relatively stationary with the conveyor plate, making it less likely for the sludge to slip onto the housing or conveyor chain assembly, thus reducing the possibility of caking on the housing or conveyor chain assembly; secondly, because the vibration... The vibrating mechanism is installed inside the housing and located above the discharge port. The vibrating part of the vibrating mechanism is located on the conveying path of the conveying plate. Therefore, when the conveying plate moves to the discharge port, the vibrating part of the vibrating mechanism can vibrate and shake the sludge on the conveying plate to the discharge port, reducing the amount of sludge accumulated on the conveying chain plate and reducing the conveying load. It can be seen that this embodiment effectively increases the amount of sludge discharged and reduces the sludge accumulation by keeping the conveying plate horizontal to reduce the movement of sludge and by shaking the sludge on the conveying plate with the vibrating mechanism when the conveying plate is near the discharge port.

[0048] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0049] Traditional sludge conveyors suffer from limitations due to their inherent properties and the resulting low sludge output and tendency to accumulate. Specifically, this manifests in the following ways: First, in existing conveying methods, scraper conveyors restrict chain oscillation and the formation of conveying space by vertically conveying the chain. Adding baffles inside the housing further reduces the internal space. Because of the sludge's stickiness, it tends to clump together on the vertically conveying surface near the housing after a period of transport. Second, sticky sludge not only tends to clump on the housing but also accumulates on the surface of the conveying plates.
[0050] In response to the above problems, the applicant found that some equipment on the market has already undergone preliminary improvements, such as adding pads to the inside of the housing, changing the material of the scraper, and adding chain guides. However, these measures are only temporary solutions and do not address the root cause. After a period of use, the problems still reappear, and they also increase maintenance costs.
[0051] Therefore, this utility model provides a Z-type conveyor and sludge conveying system for conveying sludge, which solves the technical problems of low sludge output and easy sludge stockpiling in the prior art, so as to reduce sludge caking.
[0052] Please see Figures 1 to 3 The first aspect of this utility model provides a Z-type conveyor for conveying sludge, comprising:
[0053] The housing 1 has an inlet 10 and an outlet 11. The housing 1 is matched with the Z-type conveyor body 2, that is, the housing 1 is also a Z-type housing 1. The inlet 10 is located at the lower part of the Z-type housing 1, and the outlet 11 is located at the upper part of the Z-type housing 1.
[0054] Z-type conveyor body 2 is installed inside housing 1. Z-type conveyor body 2 includes conveyor chain assembly 20 and conveyor plates 21 for supporting sludge. The feed end of conveyor chain assembly 20 is located below feed inlet 10, and the discharge end of conveyor chain assembly 20 is located above discharge outlet 11. Multiple conveyor plates 21 are installed on conveyor chain assembly 20. During the conveying process of conveyor plates 21 from feed end to discharge end, the plate surface of conveyor plate 21 for supporting sludge remains horizontal.
[0055] Vibration mechanism 3 is installed inside the housing 1 and located above the discharge port 11. The vibration part of vibration mechanism 3 is located on the conveying path of conveying plate 21. The vibration part is used to vibrate and shake the sludge on conveying plate 21 to discharge port 11.
[0056] In one operation of this embodiment, when the Z-type conveyor is started, sludge enters the housing 1 from the inlet 10 and falls onto the conveyor plate 21 below the feed end of the conveyor chain assembly 20. As the conveyor chain assembly 20 operates, the conveyor plate 21 carries the sludge and moves from the feed end to the discharge end. When the conveyor plate 21 carrying the sludge reaches above the discharge port 11, the vibrating part of the vibration mechanism 3 will continuously generate vibration. When the conveyor plate 21 flips downward, the sludge will be discharged from the housing 1 through the discharge port 11. At the same time, the vibration will shake off the sludge adhering to the conveyor plate 21, completing the entire conveying process.
[0057] As can be seen from the above working process, the advantages of this embodiment are as follows: First, because the surface of the conveyor plate 21 used to support the sludge is kept horizontal, the sludge can be stably placed on the conveyor plate 21 without spillage, reducing sludge accumulation and caking inside the housing 1 or on the conveyor chain assembly 20. This prevents the sludge from contacting the chain, improving the chain's service life, reducing maintenance frequency, and saving costs. Furthermore, the sludge remains relatively stationary during transportation, reducing sludge flow and minimizing sludge being squeezed by the scraper and sticking to the chain or scraper, thus reducing the failure rate and maintenance costs. Second, because the discharge port 11... A vibration mechanism 3 is provided, which can vibrate and shake out the sludge remaining on the conveyor plate 21, reducing the accumulation and hardening of sludge on the conveyor plate 21. The conveyor chain will not accumulate due to the continuous adhesion of sludge, which would increase the conveying load, affect the conveying efficiency, and reduce the service life of the conveyor chain. Thirdly, the shell 1 is not easily damaged. Since it has been replaced with a Z-type conveyor, the problem of the scraper conveyor, where the scraper is in close contact with the inner side of the shell 1, causing the scraper and chain to slide and rub against the shell 1 under their own weight, resulting in the shell 1 becoming thinner due to continuous friction and eventually breaking, will no longer occur.
[0058] In one specific embodiment, such as Figures 4 to 6 As shown, a feasible structure for the vibration mechanism 3 is further provided. The vibration mechanism 3 includes a vibration drive 30, a drive roller 31, and a vibration contact assembly 32. The vibration drive 30 is installed inside the housing 1, the drive roller 31 is installed on the output end of the vibration drive 30, and the vibration contact assembly 32 is installed on the outer wall of the drive roller 31. The vibration contact assembly 32 is used to abut against the conveying plate 21. In specific implementation, when the vibration drive 30 is started, it will drive the drive roller 31 to rotate, and the vibration contact assembly 32 installed on the outer wall of the drive roller 31 will also rotate accordingly. During the process of the conveying plate 21 carrying sludge to the discharge port 11 and flipping downward, the vibration contact assembly 32 will abut against the conveying plate 21. As the drive roller 31 continues to rotate, the vibration contact assembly 32 will generate a periodic force on the conveying plate 21, causing the conveying plate 21 to vibrate, thereby shaking off the sludge adhering to the conveying plate 21, ensuring smooth conveying process and reducing sludge residue.
[0059] In one embodiment, such as Figures 4 to 6As shown, a vibrating tentacle assembly 32 is further provided. The vibrating tentacle assembly 32 includes a plurality of first vibrating tentacle groups 320 and a plurality of second vibrating tentacle groups 321. The plurality of first vibrating tentacle groups 320 are uniformly arranged along the axis of the drive roller 31, and each first vibrating tentacle includes a plurality of first tentacle bodies 3200, which are all uniformly arranged circumferentially around the axis of the drive roller 31. The plurality of second vibrating tentacle groups 321 are uniformly arranged along the axis of the drive roller 31, and each second vibrating tentacle includes a plurality of second tentacle bodies 3210, which are all uniformly arranged circumferentially around the axis of the drive roller 31. The first vibrating tentacle groups 320 and the second vibrating tentacle groups 321 are arranged alternately. In specific implementation, when the vibration drive 30 starts and drives the drive roller 31 to rotate, the first vibration tentacles 320 and the second vibration tentacles 321 will rotate synchronously. Since the first vibration tentacles 320 and the second vibration tentacles 321 are arranged alternately, the first tentacles 3200 and the second tentacles 3210 at different positions can successively abut against the conveyor plate 21. As the drive roller 31 continues to rotate, the first tentacles 3200 and the second tentacles 3210 alternately generate high-frequency, periodic tapping vibrations on the conveyor plate 21. This high-frequency tapping vibration causes the sludge adhering to the conveyor chain to fall off through high-frequency vibration, thereby more effectively shaking off the sludge adhering to the conveyor plate 21 to minimize sludge residue.
[0060] Based on the above embodiments, in one embodiment, in order to ensure that the sludge in each area of the conveying plate 21 is vibrated and shaken out as much as possible, the distance between the two farthest vibrating contact groups along the axial direction of the drive roller 31 is greater than or equal to the length or width of the conveying plate 21. These two vibrating contact groups can both be the first vibrating contact group 320, both be the second vibrating contact group 321, or one can be the first vibrating contact group 320 and the other the second vibrating contact group 321. Specifically, when the distance between the two farthest vibrating contact groups satisfies the condition of being greater than or equal to the length or width of the conveying plate 21, during the rotation of the vibrating contact groups driven by the drive roller 31, it can be ensured that the entire surface of the conveying plate 21 is subjected to the action of the vibrating contact groups, and the sludge in each part of the conveying plate 21 can be vibrated and shaken out, further improving the sludge cleaning effect and effectively avoiding the problem of sludge residue due to insufficient vibration in some areas.
[0061] Based on the above embodiments, in order to avoid damage to the conveyor plate 21, in one embodiment, the first tentacle body 3200 and the second tentacle body 3210 are both soft tentacles. The soft tentacles can be made of elastic materials such as rubber or silicone. In specific implementation, the soft tentacles will not generate excessive impact force when they come into contact with the conveyor plate 21, thereby effectively avoiding damage to the conveyor plate 21 due to hard collisions. They can also adapt to a certain degree of deformation according to the surface shape of the conveyor plate 21, making the contact between the tentacles and the conveyor plate 21 tighter, and further improving the effect of vibration shaking out sludge.
[0062] Based on the above embodiments, in order to have sufficient elasticity to avoid damage to the conveyor plate 21 and to ensure that the sludge is effectively shaken out during vibration, the Shore hardness of the soft tentacles is 40-60. In specific implementation, soft tentacles with Shore hardness in this range are adopted, which have sufficient elasticity to avoid damage to the conveyor plate 21 and to ensure that the sludge is effectively shaken out during vibration.
[0063] Based on the above embodiments, such as Figures 4 to 6 As shown, in order to avoid obstructing the normal conveying process, in a specific embodiment, when the vibrating contact assembly 32 abuts against the conveying plate 21, the vibrating contact assembly 32 is located on the back of the conveying plate 21. In a specific implementation, the vibrating contact assembly 32 is set on the back of the conveying plate 21. In this way, during the vibration process, the vibration direction of the sludge is opposite to the direction of sludge falling. This arrangement will not affect the normal conveying process of sludge on the front of the conveying plate 21, ensuring the continuity and stability of the entire sludge conveying process. Moreover, when the vibrating contact assembly 32 located on the back of the conveying plate 21 is running, the vibration it generates has less interference with the working environment on the front of the conveying plate 21, reducing the adverse effects on other related equipment or operations caused by vibration.
[0064] In one specific embodiment, such as Figures 1 to 3As shown, a feasible structure for the conveyor chain assembly 20 is further provided. The conveyor chain assembly 20 includes a conveyor drive 200, a drive roller 201, two conveyor chain groups 202, and a driven roller 203. The conveyor drive 200 is installed inside the housing 1. The drive roller 201 is installed on the output end of the conveyor drive 200. The drive roller 201 is located at [location missing]. The drive roller 201 is drively connected to both conveyor chain groups 202, that is, the drive roller 201 can drive the two conveyor chain groups 202 to move synchronously. Specifically, [details missing]. The movement speed is approximately 0.2-0.3 m / s; two conveyor chain groups 202 are arranged in parallel; each conveyor chain group 202 includes an outer chain 2020 and an inner chain 2021; the outer chain 2020 includes an outer Z-shaped conveyor chain body 20200 and an outer Z-shaped rotary chain body 20201, which are connected end to end; the inner chain 2021 includes an inner Z-shaped conveyor chain body 20210 and an inner Z-shaped rotary chain body 20211, which are connected end to end. 0 and the inner Z-shaped rotary chain 20211 are connected end to end; the horizontal conveying section of the outer Z-shaped conveying chain 20200 is arranged parallel to the horizontal conveying section of the inner Z-shaped conveying chain 20210; the vertical lifting section of the outer Z-shaped conveying chain 20200 is arranged parallel to the vertical lifting section of the inner Z-shaped conveying chain 20210; multiple driven rollers 203 are respectively driven at the turning points of the outer Z-shaped conveying chain 20200, the turning points of the outer Z-shaped rotary chain 20201, and the turning points of the inner Z-shaped conveying chain 20210. At the bend and the turn of the inner Z-shaped rotating chain 20211, a first gap 2022 is left between the two conveyor chain groups 202, and a second gap 2023 is left between the vertical lifting section of the outer Z-shaped conveyor chain 20200 and the vertical lifting section of the inner Z-shaped conveyor chain 20210. The first gap 2022 and the second gap 2023 are respectively matched with the length and width of the conveyor plate 21; the four corners of the conveyor plate 21 are horizontally pivotally connected to the two outer chains 2020 and the two inner chains 2021, that is, as shown... Figure 2 As shown, along the width direction of the conveyor plate 21, one of the two corners of the near end of the conveyor plate 21 is pivotally connected to the outer chain 2020, and the other corner is pivotally connected to the inner chain 2021. The same applies to the far end of the conveyor plate 21, which will not be elaborated on here.
[0065] In this specific implementation, the start of the conveying drive 200 drives the active roller 201 to rotate. Since the active roller 201 is connected to both conveying chain groups 202, the rotation of the active roller 201 will synchronously drive the movement of the two conveying chain groups 202. The driven roller 203 provides support and guidance at each turn. The conveying plate 21 moves slowly with the conveying chain group 202. After passing through the horizontal section, it changes direction from horizontal to vertical movement. Then, through the sprocket, it changes direction from vertical to horizontal movement. When it reaches the output end, it starts to turn and rotate back. The conveying plate 21 rotates back to the initial position.
[0066] Understandably, since the two conveyor chain groups 202 are arranged in parallel, and the horizontal conveying section of the outer Z-shaped conveyor chain 20200 and the horizontal conveying section of the inner Z-shaped conveyor chain 20210 in each conveyor chain group 202 are arranged in parallel, the four corners of the conveyor plate 21 are pivotally connected horizontally to the two outer chains 2020 and the two inner chains 2021, respectively, so the conveyor plate 21 can maintain a horizontal state during horizontal conveying; since the vertical lifting section of the outer Z-shaped conveyor chain 20200 and the vertical lifting section of the inner Z-shaped conveyor chain 20210 are arranged in parallel, and the two conveyor chain groups 20202... A first interval 2022 is left between the two, and a second interval 2023 is left between the vertical lifting section of the outer Z-shaped conveyor chain 20200 and the vertical lifting section of the inner Z-shaped conveyor chain 20210. The first interval 2022 and the second interval 2023 are matched with the length and width of the conveyor plate 21, respectively, so that the conveyor plate 21 can remain horizontal during the vertical lifting and conveying process. Therefore, the above-mentioned conveyor chain structure ensures that the conveyor plate 21 can be conveyed in a horizontal state, effectively preventing sludge from slipping off the conveyor plate 21 during the conveying process, and ensuring the stability and continuity of sludge conveying.
[0067] In this embodiment, as Figure 2 and Figure 3 As shown, the first Z-shaped conveyor chain includes a first horizontal chain segment one, a first vertical chain segment, and a first horizontal chain segment two connected in sequence; the first Z-shaped conveyor chain also includes a second horizontal chain segment one, a second vertical chain segment, and a second horizontal chain segment two connected in sequence; the first horizontal chain segment one and the second horizontal chain segment one are arranged horizontally parallel; the first vertical chain segment and the second vertical chain segment are arranged vertically parallel; the second horizontal chain segment one and the second horizontal chain segment one are arranged horizontally parallel. When the conveyor plate 21 is horizontally conveyed by the two first horizontal chain segments one and the two second horizontal chain segments one, the conveyor plate 21 can remain horizontal; similarly, when the conveyor plate 21 is horizontally conveyed by the two first horizontal chain segments two and the two second horizontal chain segments two, the conveyor plate 21 can also remain horizontal; when the conveyor plate 21 is vertically conveyed by the first vertical chain segment and the second vertical chain segment, the conveyor plate 21 can also remain horizontal.
[0068] It can be understood that, through the Z-shaped conveyor configuration in this embodiment, the sludge and conveyor plate 21 no longer have close contact with the inner side of the housing 1. This avoids the situation in traditional buried scraper conveyors where the scraper is in close contact with the inner side of the housing 1, and the scraper and chain use their own weight to generate sliding friction with the housing 1. This causes the housing 1 to continuously become thinner due to friction from the scraper and chain, eventually leading to damage to the housing 1. This can result in material leakage or, in severe cases, the scraper and housing 1 jamming, causing damage to the entire conveying equipment. Furthermore, this embodiment's structural design can reduce the required motor power, avoiding the problem in traditional buried scraper conveyors where a large pulling force is required to pull the chain, necessitating a high-power motor and increasing hourly operating costs.
[0069] Based on the above embodiments, such as Figure 7 and Figure 8 As shown, to improve the service life of the conveyor chain assembly 20, the conveyor plate 21, the drive roller 201, the conveyor chain assembly 202, and the driven roller 203 are all made of corrosion-resistant materials. These materials can be rubber, PVC, etc. Those skilled in the art can select the specific materials according to their needs. In practice, using corrosion-resistant materials for the drive roller 201, conveyor chain assembly 202, and driven roller 203 can effectively resist the erosion of corrosive substances that may be present in the sludge, reducing component damage and performance degradation caused by corrosion. This significantly extends the service life of the entire conveyor chain assembly 20, avoiding the problem of short service life caused by the sludge conveying process having to come into contact with the chain, as in traditional technologies (according to the applicant's research, the service life of chains made of ordinary materials is generally three months under the extremely corrosive conditions of sludge. Even replacing them with stainless steel chains does not significantly improve the situation, but greatly increases costs).
[0070] Please see Figure 1 The second aspect of this utility model provides a sludge conveying system, comprising:
[0071] The first aspect is the Z-type conveyor a;
[0072] A cylindrical feeding device b is aligned with the discharge port of the Z-type conveyor a.
[0073] The hopper (not shown in the figure) is connected to the feeding device b.
[0074] In the operation of this embodiment, when the front end of the conveyor plate reaches the discharge port, the feeding device b starts according to the electronic control program setting, spreading the sludge on the conveyor plate. When the rear end of the conveyor plate reaches the feed port, the feeding device b stops. When the feeding device b spreads the material, it covers the internal area of the PVC plate to the maximum extent until the front end of the next conveyor chain plate reaches the discharge port, at which point the feeding device b starts again.
[0075] It is understood that the sludge conveying system in this embodiment adopts the structure of Z-type conveyor a, which realizes continuous and stable conveying of sludge in the vertical and horizontal directions, so as to meet the sludge conveying requirements in different scenarios, effectively increase the sludge output, and reduce the situation of sludge stockpiling in the sludge conveying system.
