Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment devices, specifically an anti-clogging sludge conveying device. Background Technology

[0002] Sludge transportation and drying is a crucial part of sludge treatment. Automated sludge drying and transportation systems can continuously and efficiently complete sludge treatment in large quantities.

[0003] The existing sludge treatment method uses a horizontally placed screw conveyor with a feed hopper on the upper side of one end and a discharge port on the lower side of the other end. The sludge added through the feed hopper can move towards the discharge port. At the same time, the screw conveyor adopts an inner and outer cylinder structure, and by conveying hot steam between the inner and outer cylinders, the sludge can be dried during transportation. However, this sludge drying treatment method still has some problems in use.

[0004] Specifically, sludge addition is usually accomplished using a loading truck. To ensure thorough sludge drying, a low conveying speed is required. This necessitates controlling the unloading speed of the loading truck to guarantee the drying effect, which in turn requires a longer unloading time. Furthermore, there is a certain turnover period between the unloading and the next unloading, making each sludge drying process time-consuming. If all the sludge in the loading truck is unloaded into the feed hopper at once, the high water content and strong viscosity of the sludge can easily cause blockage at the feed end of the screw conveyor. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides an anti-clogging sludge conveying device.

[0006] The technical solution of this utility model is as follows:

[0007] A clogging-resistant sludge conveying device includes a horizontally arranged body. A feed hopper is provided on the upper side of one end of the body, and a discharge port is provided on the lower side of the other end. Sludge can be fed into the feed hopper and discharged through the discharge port, and the drying process is completed during the transportation inside the body.

[0008] As the core technical concept of this utility model, the feed hopper is also equipped with an anti-blocking mechanism. Specifically, the anti-blocking mechanism includes horizontally arranged, slidingly inserted door into the feed hopper from the outside. Two doors are arranged opposite each other, and the two doors are connected to a drive unit capable of driving them to slide in opposite directions. The anti-blocking mechanism has several sets of vertical gaps. Based on this structure, when sludge is added to the feed hopper by a loading trolley, the doors of the anti-blocking mechanism can close sequentially from bottom to top, allowing the sludge to be stored in batches in the space above the doors. The opening and closing of the anti-blocking mechanisms can be controlled. The doors open sequentially from bottom to top, completing the sludge drying process in batches. This method of storing and discharging sludge in batches through the feeding hopper allows the sludge in the loading vehicle to be unloaded into the feeding hopper all at once, without worrying about a large amount of sludge clogging the machine body at once. At the same time, by controlling the opening and closing speed of the doors, the sludge discharge speed can be controlled, thereby ensuring the sludge drying effect. Furthermore, the doors are designed with two panels, which makes it easy to open and close the doors even if there is some adhesion between the sludge and the doors. On the other hand, it allows the sludge to fall from the middle of the feeding hopper and then smoothly into the machine body to complete the drying process.

[0009] As described above, in a preferred embodiment of the anti-clogging sludge conveying device, to further prevent sludge from clogging the machine body near the feed hopper, the machine body includes a filling cavity corresponding to the lower end of the feed hopper, and the volume of the space enclosed by the opening and closing doors of the feed hoppers of the two adjacent anti-clogging mechanisms is adapted to the volume of the filling cavity.

[0010] As described above, in terms of the installation method of the switch door and the feed hopper, the anti-clogging mechanism further includes two roller sets disposed on the two opposite inner walls of the feed hopper. The roller sets include two rows of rollers arranged vertically. The switch door is slidably disposed between the two rows of rollers, which further makes the opening and closing of the switch door under the action of the rollers smoother.

[0011] In a preferred embodiment, to prevent sludge from leaking into the lower layer on both sides of the switch door, the two sides of the switch door are fitted to the inner wall of the feed hopper.

[0012] As described above, the anti-clogging sludge conveying device, in terms of the way the drive unit drives the opening and closing of the switch door, includes a telescopic drive motor that is connected to the switch door in a transmission manner, and a controller that is connected to the telescopic drive motor in communication. The controller is configured to control the telescopic stroke and telescopic speed of the telescopic drive motor, thereby controlling the sludge feeding speed, preventing sludge blockage while ensuring the sludge drying treatment effect.

[0013] As a preferred embodiment, in order to make it easier to control the travel and speed of the door opening and closing, the telescopic drive is a linear motor.

[0014] As a further preferred embodiment, to facilitate the material receiving operation of the feed hopper, the feed hopper has an inverted trapezoidal structure that is larger at the top and smaller at the bottom.

[0015] As described above, the anti-clogging sludge conveying device specifically includes an inner cylinder and an outer cylinder with an inner and outer sleeve and a gap between them. The inner cylinder is provided with a spiral blade, and one end of the outer cylinder is provided with a drive motor that is connected to the spiral blade. The two ends of the outer cylinder are respectively provided with a steam inlet and a steam outlet.

[0016] The beneficial effects of this utility model are as follows: This utility model is an anti-clogging sludge conveying device. When sludge is added to the feed hopper by the feeding car, the opening and closing doors of several anti-clogging mechanisms can be closed sequentially from bottom to top, so that the sludge can be stored in batches in the space above the opening and closing doors of several anti-clogging mechanisms. By controlling the opening and closing doors of several anti-clogging mechanisms to open sequentially from bottom to top, the sludge drying process is completed in batches. This method of storing and discharging sludge in batches through the feed hopper allows the sludge in the feeding car to be unloaded into the feed hopper at one time, without worrying about a large amount of sludge clogging the machine body at once. At the same time, by controlling the opening and closing speed of the opening and closing doors, the discharge speed of the sludge can be controlled, thereby ensuring the drying process of the sludge. Moreover, the opening and closing doors are set with two doors, which makes it easy to open and close the doors even if there is adhesion between the sludge and the opening and closing doors. On the other hand, it allows the sludge to fall from the middle of the feed hopper and then smoothly fall into the machine body to complete the drying process. Attached Figure Description

[0025] Example

[0026] This embodiment provides an anti-clogging sludge conveying device; see [link / reference]. Figure 1 The device includes a horizontally arranged body 1. One end of the body 1 has an upper feed inlet, and the upper side of the feed inlet is connected to a feed hopper 2. The other end of the body 1 (the end away from the feed inlet) has a lower discharge outlet, and the lower side of the discharge outlet is connected to a protective cover 3. The protective cover 3 is designed to prevent the dried sludge from splashing when it is transported out of the discharge outlet. The sludge can be put into the feed inlet from the feed hopper 2 and transported out through the protective cover 3 at the discharge outlet. At the same time, the drying process is completed during the transportation inside the body 1. The structure of the drying device (the above-mentioned anti-clogging sludge conveying device) will be described in detail below with reference to the accompanying drawings.

[0027] In this embodiment, Europe and China, combined with Figure 1 Specifically, the structure of the machine body 1 includes an inner cylinder and an outer cylinder with an inner and outer sleeve and a gap between them. The inner cylinder is provided with a spiral blade 6 inside, and a drive motor 4 connected to the spiral blade 6 is provided at one end of the outer cylinder. The two ends of the outer cylinder are respectively provided with a steam inlet and a steam outlet. The drive motor 4 can drive the spiral blade 6 to rotate, thereby transporting the sludge from the feed port to the discharge port. The hot steam required for sludge drying can enter from the steam inlet and flow out from the steam outlet, thereby enabling the sludge to complete the drying process during transportation.

[0028] Furthermore, a speed reducer is connected to one end of the outer cylinder via a quick flange. The drive motor 4 and the spiral blade 6 are both connected to the speed reducer 5 to ensure the rotational speed of the spiral blade 6, thereby ensuring the transport speed of the sludge and ultimately ensuring the drying effect of the sludge.

[0029] As a preferred embodiment, to facilitate the material receiving operation of the feed hopper 2, the feed hopper 2 has an inverted trapezoidal structure that is larger at the top and smaller at the bottom.

[0030] In this embodiment, as the core technical concept of this utility model, the feed hopper 2 is also provided with an anti-blocking mechanism 7 to avoid blockage at the feed inlet due to the high water content and strong viscosity of the sludge.

[0031] Specifically, the anti-blocking mechanism 7 includes horizontally arranged opening and closing doors 71 that are slidably inserted into the feed hopper 2 from the outside of the feed hopper 2. Two opening and closing doors 71 are arranged opposite each other, and the two opening and closing doors 71 are driven by a drive unit capable of driving them to slide in opposite directions. The anti-blocking mechanism 7 has several sets of vertical gaps. Based on this structure, when sludge is added to the feed hopper 2 by a loading trolley, the opening and closing doors 71 of the several anti-blocking mechanisms 7 can close sequentially from bottom to top, allowing the sludge to be stored in batches in the space above the opening and closing doors 71 of the several anti-blocking mechanisms 7. Furthermore, by controlling the opening and closing doors 71 of the several anti-blocking mechanisms 7 to open sequentially from bottom to top, the sludge can be stored in batches. The sludge drying process is completed in batches. This method of storing and discharging sludge in batches through the feed hopper 2 allows the sludge in the loading vehicle to be unloaded into the feed hopper 2 at once, without worrying about a large amount of sludge clogging the machine body 1 at once. At the same time, by controlling the opening and closing speed of the switch door 71, the sludge discharge speed can be controlled, thereby ensuring the sludge drying effect. The switch door 71 is designed with two doors, which makes it easy to open and close the switch door 71 even if there is some adhesion between the sludge and the switch door 71. On the other hand, it allows the sludge to fall from the middle of the feed hopper 2 and then fall smoothly into the machine body 1 to complete the drying process.

[0032] As a preferred embodiment, in order to further prevent sludge from clogging the end of the machine body 1 near the feed hopper 2, the machine body 1 is configured to include a filling cavity 11 corresponding to the lower end of the feed hopper 2 and a processing cavity 12 connected thereto. The volume of the space enclosed by the opening and closing doors 71 of the two adjacent anti-clogging mechanisms 7 and the walls of the feed hopper 2 is adapted to the volume of the filling cavity 11.

[0033] Combination Figure 2 Specifically, regarding the installation method of the switch door 71 and the feed hopper 2, the anti-blocking mechanism 7 also includes two sets of rollers 72 disposed on the two opposite inner walls of the feed hopper 2. The sets of rollers 72 include two rows of rollers 72 arranged vertically. The switch door 71 is slidably disposed between the two rows of rollers 72, which further makes the opening and closing of the switch door 71 under the action of the rollers 72 smoother.

[0034] As a further preferred embodiment, to prevent sludge from leaking into the lower layer on both sides of the switch door 71, the two sides of the switch door 71 are fitted to the inner wall of the feed hopper 2.

[0035] Combination Figure 3Regarding the way the drive unit drives the opening and closing of the switch door 71, the drive unit includes a telescopic drive motor that is connected to the switch door 71 in a transmission manner, and a controller that is connected to the telescopic drive motor in communication. The controller is configured to control the telescopic stroke and telescopic speed of the telescopic drive motor, thereby controlling the sludge feeding speed, preventing sludge blockage, and ensuring the sludge drying treatment effect.

[0036] As a preferred embodiment, in order to make it easier to control the travel and opening / closing speed of the door 71, the telescopic drive is a linear motor 76.

[0037] As a further preferred embodiment, to ensure the smooth opening and closing of the door 71, each anti-blocking mechanism 7 includes two sets of drive units located opposite each other on both sides of the feed hopper 2. Specifically, each drive unit includes a protective box 73 located outside the feed hopper 2. Inside the protective box 73, along the sliding direction of the door 71, are two rotating gears 74. A drive chain 75 is located between the gears 74. A linear motor 76 is located inside the protective box 73 and is connected to the drive chain 75. The movement of the linear motor 76 drives the chain 75. The drive unit also includes a sliding... Two drive rods 77 are inserted on both sides of the protective box 73 along the sliding direction of the opening and closing door 71. The outer ends of the two drive rods 77 are connected to the outer sides of the two opening and closing doors 71, and the inner ends are fixed to the drive chain 75. The fixed ends of the two drive rods 77 and the drive chain 75 are located on the upper and lower sides of the chain, respectively. Based on this structure, when the linear motor 76 drives the drive chain 75 to move, the two drive rods 77 can move synchronously in opposite directions under the drive of the drive chain 75, so as to ensure the consistency of the action of the two opening and closing doors 71, and make the control of the opening and closing speed and opening and closing distance of the opening and closing doors 71 more precise and reliable.

[0038] Preferably, to further ensure the stability of the extension and retraction of the drive rod 77, the protective box 73 is also provided with a guide block 78, through which the drive rod 77 slides.
