Description

Technical Field

[0001] The utility model relates to the technical field of sludge conveying, in particular to a temporary sludge conveying device. Background Art

[0002] In the process of sewage purification, a lot of sludge is usually separated from the sewage. The sludge usually contains water, microbial communities, organic matter and inorganic substances. The water content in the sludge can usually reach more than 60%, and the sludge usually contains more pathogens, heavy metals and persistent organic matter and other toxic and harmful substances. Without effective treatment and disposal, the harmful substances in the sludge can easily penetrate through the water contained in itself to cause secondary pollution to groundwater, soil, etc., directly threatening environmental safety and public health. Therefore, when treating the sludge, it is usually necessary to treat the sludge harmlessly. In the process of sludge treatment, the sludge needs to be transported between different devices through a conveyor belt.

[0003] For example, the patent document with the announcement number CN219173377U discloses a sludge conveyor belt, including a conveyor belt body, two groups of friction discs are sleeved inside the conveyor belt body, a transmission shaft is fixedly arranged at the center of each group of friction discs, and the two ends of the transmission shaft are movably connected and arranged inside the support leg, a groove is opened on the surface of the left support leg, a slider is slidably arranged inside the groove, and a bracket is fixedly arranged on the surface of the slider, a scraper is movably arranged at the end of the bracket, a damping shaft is inserted and arranged at the center of rotation of the scraper and the bracket, and the scraper is triangular, and the upper surface of the scraper fits the bottom of the conveyor belt body. This technical solution is provided with a rolling roller, and by controlling the height of the rolling roller, the contact area between the rolling roller and the conveyor belt body itself is changed, thereby achieving the effect of controlling the rolling of sludge of different hardness, and a scraper is fixedly arranged at the end of the conveyor belt body, and the stubborn sludge remaining on the surface is cleaned by the scraper, thereby reducing the energy loss in the process of transporting sludge.

[0004] Although the above technical scheme can reduce the adhesion of sludge on the conveyor belt during transportation, since the water content of sludge is usually high, the sludge is easy to form a tight mud mass under the adhesion effect of water, and in the process of sludge transportation, the sludge comes into contact with the air to evaporate the water, which reduces the water content in the sludge, resulting in the sludge surface becoming dry and compacted during transportation to form large hard mud blocks, which increases the amount of sludge adhered to the conveyor belt, increases the pressure of conveyor belt cleaning, and the compacted sludge is not conducive to purification by the treatment device, affecting the sludge treatment effect. Utility Model Content

[0005] The utility model aims to provide a temporary sludge conveying device to solve the technical problem that the sludge on the conveyor belt is prone to drying and hardening during the sludge conveying process in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a temporary sludge conveying device, including a frame and a conveyor belt, driving rollers are provided at both ends of the frame, the conveyor belt is sleeved on the driving rollers, and the driving rollers are used to drive the conveyor belt to move; a plurality of support roller groups are provided on the frame, and the plurality of support roller groups are evenly distributed on the frame along the extension direction of the frame, the support roller groups are parallel to each other, a recessed area is provided in the middle of the support roller group, and the support roller group is used to support the conveyor belt; a vibrating member is provided in the support roller group, and the vibrating member is used to drive the conveyor belt to vibrate.

[0007] The principle and advantage of this scheme are: when conveying sludge, the conveying device is placed at the position where the sludge needs to be conveyed, and the sludge is conveyed to the surface of the conveyor belt through a screw conveyor or a mud pump and other equipment. The conveyor belt drives the sludge to move under the drive of the driving roller to transport the sludge. During the sludge conveying process, the vibrating member in the support roller group drives the support roller group to vibrate and drives the conveyor belt to vibrate, so that the sludge on the surface of the conveyor belt vibrates.

[0008] In this solution, when conveying sludge, a support roller group with a recessed area is provided on the frame, so that the conveyor belt can form a recessed area on the support roller group. When conveying sludge, the sludge can be located in the recessed area of ​​the conveyor belt, avoiding the sludge being removed from the edge of the conveyor belt during the conveying process and causing pollution to the processing environment. In addition, by providing multiple support roller groups on the frame to support the conveyor belt, while ensuring that the bottom of the conveyor belt has sufficient support, the support roller group drives the surface of the conveyor belt to vibrate, so that the sludge can vibrate continuously during the conveying process, ensuring that the sludge can remain loose under the action of vibration during the conveying process, preventing the sludge from agglomerating and solidifying into a mass, reducing the amount of sludge adhering to the surface of the conveyor belt, and facilitating the processing of the sludge.

[0009] Preferably, as an improvement, a first support frame and a second support frame for supporting the frame are respectively provided at both ends of the frame, the length of the second support frame in the height direction is retractable, and the second support frame is used to adjust the inclination angle of the frame. By adjusting the inclination angle of the frame, the frame can transport sludge between devices at different heights, thereby improving the compatibility of the transport device with different devices.

[0010] Preferably, as an improvement, rollers are provided at one end of the first support frame and the second support frame away from the frame body, and the rollers are used to drive the frame body to move, so that the conveying device can adjust its position according to actual needs, thereby improving the flexibility of the sludge conveying device.

[0011] Preferably, as an improvement, a fixing chain is provided at one end of the first support frame and the second support frame away from the frame body, and the fixing chain is used to fix the frame body, so that the position of the sludge conveying device can be fixed when the sludge conveying device is conveying sludge, thereby preventing the sludge conveying device from being offset during operation and causing sludge leakage.

[0012] Preferably, as an improvement, the support roller group includes two support rollers, which are distributed facing each other on both sides of the center line of the frame in the width direction; the support rollers are rotatably connected to the frame, so that the support roller group can independently support both sides of the conveyor belt, so that when the sludge on the conveyor belt is unevenly distributed, the support roller group can provide different support forces on both sides of the conveyor belt to ensure the smooth operation of the conveyor belt.

[0013] Preferably, as an improvement, the height of the support roller near the edge of the frame is higher than the height of the support roller near the center of the frame. By placing the support roller at an angle, the support roller can effectively support both sides of the conveyor belt while increasing the contact area between the support roller and the conveyor belt, thereby improving the support effect of the support roller on the conveyor belt.

[0014] Preferably, as an improvement, the surface of the conveyor belt is provided with a plurality of anti-skid grooves, which are evenly arranged on the conveyor belt, so that when the conveyor belt is conveying sludge, the friction force on the surface of the conveyor belt can be increased, and the sludge can be prevented from sliding too fast on the conveyor belt due to the angle of the frame being too large, so that the end of the conveyor belt cannot discharge the sludge in time, causing the sludge to accumulate and overflow.

[0015] Preferably, as an improvement, scrapers are respectively provided at both ends of the frame, the scrapers are in contact with the surface of the conveyor belt, and the scrapers are used to scrape the sludge on the surface of the conveyor belt, so that the sludge remaining on the surface of the conveyor belt can be cleaned in time under the action of the scrapers, avoiding the continuous accumulation of sludge on the conveyor belt, ensuring the cleanliness of the conveyor belt, and reducing the operating load of the conveying device.

[0019] The following is further described in detail through specific implementation methods:

[0020] The reference numerals in the drawings of the specification include: frame 1, first support frame 101, second support frame 102, roller 103, fixed chain 104, driving roller 105, motor 106, conveyor belt 2, anti-skid groove 201, support roller 3, scraper 4.

[0021] As attached Figure 1 As shown, a temporary sludge conveying device comprises a frame 1, on which a conveyor belt 2 is laid. The conveyor belt 2 can move on the frame 1, and the conveyor belt 2 is used to drive the sludge to move.

[0022] The frame 1 is a metal bracket, the extension direction of the frame 1 is consistent with the feeding direction, and the frame 1 is inclined from bottom to top along its own extension direction. Specifically, one end of the frame 1 is the starting end, and the other end is the tail end. The position of the starting end of the frame 1 in the height direction is lower than the position of the tail end of the frame 1 in the height direction. A first support frame 101 is provided at the starting end of the frame 1, and one end of the first support frame 101 is rotatably connected to the frame 1 through a rotating shaft, and the end of the first support frame 101 away from the frame 1 is used to contact the ground; a second support frame 102 is provided at the tail end of the frame 1, and one end of the second support frame 102 is rotatably connected to the frame 1 through a rotating shaft, and the end of the second support frame 102 away from the frame 1 is used to connect to the ground, wherein the length of the second support frame 102 in the height direction is retractable, and the second support frame 102 is used to adjust the inclination angle of the frame 1, and the specific second support frame 102 is composed of a telescopic rod in the area extending in the height direction, wherein the specific structure of the telescopic rod is the prior art and will not be repeated here. By placing the frame 1 at an angle, the sludge conveying speed can be increased by utilizing the fluidity of the sludge itself when conveying the sludge, thereby preventing the sludge from accumulating and sticking on the conveyor belt 2. At the same time, by adjusting the inclination angle of the frame 1, the frame 1 can convey the sludge between equipment at different heights, thereby improving the compatibility of the conveying device with different devices.

[0023] The first support frame 101 and the second support frame 102 are both fixedly connected with rollers 103 by bolts at one end away from the frame body 1. The rollers 103 are used to drive the frame body 1 to move. Specifically, two rollers 103 are installed at one end of the first support frame 101 and the second support frame 102 away from the frame body 1. The two rollers 103 are respectively located on both sides of the frame body 1. Preferably, the rollers 103 in this embodiment are universal wheels. This allows the conveying device to adjust its position according to actual needs, thereby improving the flexibility of the sludge conveying device.

[0024] A fixing chain 104 is also provided at one end of the first support frame 101 and the second support frame 102 away from the frame body 1, one end of the fixing chain 104 is fixedly connected to the first support frame 101 or the second support frame 102 by bolts, and the other end is a free end, and the free end of the fixing chain 104 is used to connect to the ground or an external structure to fix the position of the frame body 1. When the sludge conveying device is conveying sludge, the position of the sludge conveying device can be fixed to avoid sludge leakage caused by position deviation of the sludge conveying device during operation.

[0025] The starting end and the tail end of the frame 1 are rotatably connected with a driving roller 105 through a rotating shaft, and the two ends of the driving roller 105 rotating shaft are respectively rotatably connected with the two sides of the frame 1, and the rotating shaft of the driving roller 105 is connected with the output shaft of the motor 106 through a transmission belt. Preferably, in the embodiment, the driving roller 105 located at the starting end of the frame 1 is the main driving roller 105, and the driving roller 105 located at the tail end of the frame 1 is the slave driving roller 105, wherein the main driving roller 105 located at the starting end of the frame 1 is connected to the motor 106, and the motor 106 drives the main driving roller 105 to rotate. While ensuring that the conveyor belt 2 can have sufficient power to transport the sludge, the power consumption of the conveying device during operation is reduced, and the energy loss during operation is reduced.

[0026] The conveyor belt 2 is an annular conveyor belt 2. Preferably, in this embodiment, the conveyor belt 2 is a soft rubber conveyor belt 2. The conveyor belt 2 is sleeved on the frame 1, and the conveyor belt 2 is in contact with the surface of the driving roller 105 at both ends of the frame 1. The driving roller 105 is used to drive the conveyor belt 2 to move circumferentially around the frame 1.

[0027] A plurality of support roller groups are arranged on the frame 1, and the plurality of support roller groups are evenly distributed on the frame 1 along the extension direction of the frame 1, and the support roller groups are parallel to each other, and the support roller groups are used to support the conveyor belt 2 on the frame 1. Figure 2As shown, each support roller group includes two support rollers 3, and the two support rollers 3 are distributed opposite to each other on both sides of the center line A in the width direction of the frame 1; both ends of the support roller 3 are connected to the frame 1 through a support rod, and one end of the support rod is fixedly connected to the frame 1 by bolts or welding, and the other end extends upward in the height direction, and the end of the support rod away from the frame 1 is rotatably connected to the axis of the support roller 3 through a rotating shaft. The central axis of the support roller 3 is tilted downward from the edge of the frame 1 to the center of the frame 1, and the height of the support roller 3 near the edge of the frame 1 is higher than the height of the support roller 3 near the center of the frame 1, so that a concave area is formed in the middle of the support roller group, and the conveyor belt 2 is laid on the support roller group, so that a concave area is formed on the conveyor belt 2. The conveyor belt 2 can be effectively supported on the frame 1, and while ensuring the stability of the conveyor belt 2, a stable concave area can be formed on the conveyor belt 2 to hold the sludge, thereby increasing the carrying capacity of the conveyor belt 2 when transporting the sludge.

[0028] A vibrating member is provided in each support roller 3. Specifically, each support roller 3 is a hollow structure. A vibrating member is fixedly installed in each support roller 3 by bolts. The vibrating member is used to drive the outer wall of the support roller 3 to vibrate, so that the conveyor belt 2 vibrates during the conveying process. The specific vibrating member can be a vibration motor. The specific structure of the vibrating member is a prior art and will not be described here. By vibrating the conveyor belt 2 during the conveying process, the sludge is prevented from being in a static state on the surface of the conveyor belt 2 for a long time, which causes the sludge to become compacted and adhere to the surface of the conveyor belt 2 due to the evaporation of water.

[0029] As attached Figure 3 As shown, a plurality of anti-skid grooves 201 are provided on the surface of the conveyor belt 2, and the plurality of anti-skid grooves 201 are evenly arranged along the extension direction of the conveyor belt 2, and the extension direction of the anti-skid grooves 201 is perpendicular to the extension direction of the conveyor belt 2. When the conveyor belt 2 is conveying sludge, the friction force on the surface of the conveyor belt 2 can be increased, and the sludge can be prevented from sliding too fast on the conveyor belt 2 due to the excessive angle of the frame 1, so that the end point of the conveyor belt 2 is not able to discharge the sludge in time, resulting in the accumulation and overflow of the sludge.

[0030] Scrapers 4 are provided at both ends of the frame 1, and the scrapers 4 are located on the side of the frame 1 close to the ground. The two ends of the scrapers 4 are fixedly connected to the two sides of the frame 1 by bolts, and the scrapers 4 span the conveyor belt 2 and contact the surface of the conveyor belt 2. The scrapers 4 are used to scrape the residual sludge on the surface of the conveyor belt 2. The residual sludge on the surface of the conveyor belt 2 can be cleaned in time under the action of the scrapers 4, so as to avoid the continuous accumulation of sludge on the conveyor belt 2, ensure the cleanliness of the conveyor belt 2, and reduce the operation load of the conveying device.

[0031] The specific implementation process is as follows:

[0032] When the sludge is transported, the conveying device is installed at the position where the sludge needs to be transported, and the sludge is transported to the surface of the conveyor belt 2 through a screw conveyor or a mud pump. The conveyor belt 2 drives the sludge to move under the drive of the driving roller 105 to transport the sludge. During the sludge transportation process, the vibrating member in the support roller group drives the support roller group to vibrate and drives the conveyor belt 2 to vibrate, so that the sludge on the surface of the conveyor belt 2 vibrates.

[0033] Compared with the prior art, in this solution, when conveying sludge, a support roller group with a recessed area is provided on the frame 1, so that the conveyor belt 2 can form a recessed area on the support roller group. When conveying sludge, the sludge can be located in the recessed area of ​​the conveyor belt 2, avoiding the sludge from being removed from the edge of the conveyor belt 2 during the conveying process, which causes pollution to the processing environment. In addition, by providing multiple support roller groups on the frame 1 to support the conveyor belt 2, while ensuring that the bottom of the conveyor belt 2 has sufficient support, the support roller group drives the surface of the conveyor belt 2 to vibrate, so that the sludge can vibrate continuously during the conveying process, ensuring that the sludge can remain loose under the action of vibration during the conveying process, preventing the sludge from agglomerating and solidifying into a mass, reducing the amount of sludge adhering to the surface of the conveyor belt 2, and facilitating the processing of the sludge.

[0034] The above are only embodiments of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
