Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a mixing and injection device for in-situ solidification of intertidal sludge. Background Technology

[0002] The intertidal silt solidification device mainly works by introducing silt into a reaction chamber, then introducing chemical solidifying agents or other substances into the reaction chamber to mix with the silt, thereby changing its physical and chemical properties and solidifying the silt.

[0003] However, because sludge is prone to clumping, the single mixing device in existing sludge solidification equipment is difficult to fully break up the clumps, resulting in the solidifying agent and sludge not being fully mixed. Furthermore, the clumps of sludge are large in size and can easily clog the transmission pipes and discharge pipes in the equipment, thus affecting the working efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a mixing and injection device for in-situ solidification of intertidal silt, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and injection device for in-situ solidification of intertidal silt, comprising a tank, wherein the tank includes a mixing chamber, a pretreatment box and a conveying box, a silt conveying pump is provided at the top of the tank, the lower outlet of the silt conveying pump extends into the pretreatment box, a conveying channel is provided between the bottom of the pretreatment box and the top of the conveying box, and a discharge pipe is provided between the conveying box and the mixing chamber;

[0006] The stirring chamber is provided with a first rotating shaft, the bottom end of the first rotating shaft is provided with a main bevel gear, and the bottom of the main bevel gear is provided with a first driven bevel gear. The first driven bevel gear meshes with the main bevel gear. The end of the first driven bevel gear away from the main bevel gear is provided with a second rotating shaft. The end of the second rotating shaft away from the first driven bevel gear extends into the pretreatment box, and the end of the second rotating shaft extending into the pretreatment box is rotatably connected to the inner wall of the pretreatment box. Multiple sets of blades are provided on the outer wall of the second rotating shaft.

[0007] Below the main bevel gear is a second driven bevel gear that meshes with the first driven bevel gear. The lower end of the second driven bevel gear is provided with a third rotating shaft, and the lower end of the third rotating shaft is rotatably connected to the bottom of the stirring chamber.

[0008] As a preferred embodiment, the outer wall of the third rotating shaft is provided with multiple sets of stirring blades.

[0009] As a preferred embodiment, a servo motor is provided at the top of the tank, and the output end of the servo motor is connected to the first rotating shaft.

[0010] As a preferred embodiment, a drug inlet pipe is provided on the side wall of the tank, one end of which extends into the pretreatment tank, and a spray pump is provided on the drug inlet pipe.

[0011] As a preferred embodiment, the conveyor box is equipped with a conveyor located below the conveying channel.

[0012] As a preferred embodiment, the bottom of the conveyor box is provided with a placement cavity, and a drive motor is installed inside the placement cavity.

[0013] As a preferred embodiment, the bottom of the tank is provided with multiple sets of support frames.

[0014] As a preferred embodiment, a discharge pipe is provided on the outer wall of the tank, and a liquid inlet pipe is provided at the top of the tank.

[0015] As can be seen from the technical solution provided by this utility model above, the beneficial effects of the mixing and injection device for in-situ solidification of intertidal silt provided by this utility model are:

[0016] In this invention, a mixing chamber, a pretreatment box, and a conveying box are set inside the tank. The sludge is transported to the pretreatment box by a sludge conveying pump. The blades in the pretreatment box break up the clumps of sludge. The broken sludge and the curing agent are mixed together in the conveying box and then fed into the mixing box. The third rotating shaft in the mixing box further mixes the sludge and the curing agent. After thorough mixing, the mixture is discharged into the intertidal zone. The blades in the pretreatment box break up the clumps of sludge during pretreatment, which not only prevents clogging of the device but also improves the mixing effect of the sludge and the curing agent, thereby increasing the curing efficiency.

[0017] In this invention, a main bevel gear is installed at the bottom of a first rotating shaft inside the mixing chamber. Below the main bevel gear, a first driven bevel gear meshes with the main bevel gear. A second rotating shaft connects the inner wall of the pretreatment tank to the first driven bevel gear. Blades are installed on the outer wall of the second rotating shaft. Below the main bevel gear, a second driven bevel gear meshes with the first driven bevel gear. A third rotating shaft is installed at the lower end of the second driven bevel gear. When the first rotating shaft rotates, the main bevel gear drives the first driven bevel gear to rotate, which in turn causes the second rotating shaft to drive the blades to break up the sludge in the pretreatment tank. At the same time, the rotation of the first driven bevel gear drives the second driven bevel gear to rotate, which in turn drives the third rotating shaft to rotate, thus fully mixing the sludge and the curing agent. Through the close connection of the above devices, rotating the first rotating shaft can break up the sludge in the pretreatment tank, and the mixing of the sludge and the curing agent can be carried out in the mixing chamber, improving the automation efficiency of the device.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figure 1-4 As shown, this utility model embodiment provides a mixing and injection device for in-situ solidification of intertidal silt, including a tank 1. The tank 1 includes a mixing chamber 11, a pretreatment box 12 and a conveying box 13. A silt conveying pump 3 is provided at the top of the tank 1. The discharge port of the silt conveying pump 3 extends into the pretreatment box 12. A conveying channel 122 is provided between the bottom of the pretreatment box 12 and the top of the conveying box 13. A discharge pipe 133 is provided between the conveying box 13 and the mixing chamber 11.

[0029] The stirring chamber 11 is provided with a first rotating shaft 111. A main bevel gear 112 is provided at the bottom end of the first rotating shaft 111. A first driven bevel gear 113 is provided below the main bevel gear 112. The first driven bevel gear 113 meshes with the main bevel gear 112. A second rotating shaft 114 is provided at the end of the first driven bevel gear 113 away from the main bevel gear 112. The end of the second rotating shaft 114 away from the first driven bevel gear 112 extends into the pretreatment box 12, and the end of the second rotating shaft 114 extending into the pretreatment box 12 is rotatably connected to the inner wall of the pretreatment box 12. Multiple sets of blades 121 are provided on the outer wall of the second rotating shaft 114.

[0030] Below the main bevel gear 112, a second driven bevel gear 115 is provided, which meshes with the first driven bevel gear 113. A third rotating shaft 116 is provided at the lower end of the second driven bevel gear 115, and the lower end of the third rotating shaft 116 is rotatably connected to the bottom end of the stirring chamber 11.

[0031] The sludge conveying pump 3 is used to feed the sludge to be solidified from the intertidal zone into the pretreatment tank 12. The blades 121 in the pretreatment tank 12 are used to break up the clumps of sludge, which facilitates the subsequent mixing of sludge and solidifying agent. In order to ensure that the sludge and solidifying agent are fully mixed, the broken sludge and solidifying agent are conveyed to the conveying tank 13 through the conveying channel 122 for preliminary mixing, and then enter the mixing chamber 11 through the conveying discharge pipe 133. The third rotating shaft 116 is used to fully mix the sludge and solidifying agent. After mixing, the mixture is discharged to the intertidal zone. The blades in the pretreatment tank are used to break up the clumps of sludge, which not only prevents the device from being blocked, but also improves the mixing effect of sludge and solidifying agent and improves the solidification efficiency. In order to improve the automation efficiency of the device, a main bevel gear 112 is set at the bottom of the first rotating shaft 111 in the mixing chamber 11. Below the main bevel gear 112, a first meshing device is set to engage with the main bevel gear 112. A second rotating shaft 114 connects the inner wall of the pretreatment box 12 to the first driven bevel gear 113. A blade 121 is mounted on the outer wall of the second rotating shaft 114. A second driven bevel gear 115, meshing with the first driven bevel gear 113, is located below the main bevel gear 112. A third rotating shaft 116 is located at the lower end of the second driven bevel gear 115. When the first rotating shaft 111 rotates, the main bevel gear 112 drives the first driven bevel gear 113 to rotate, which in turn causes the second rotating shaft 114 to drive the blade 121 to break up the sludge in the pretreatment box 12. Simultaneously, the rotation of the first driven bevel gear 113 drives the second driven bevel gear 115 to rotate, which in turn drives the third rotating shaft 113 to rotate, thus fully mixing the sludge and the curing agent. This achieves the goal of breaking up the sludge in the pretreatment box 12 by rotating the first rotating shaft 111, and mixing the sludge and curing agent in the mixing chamber 11, improving the automation efficiency of the device.

[0032] Multiple sets of stirring blades 117 are provided on the outer wall of the third rotating shaft 116.

[0033] In order to ensure that the sludge and the curing agent are mixed more thoroughly in the mixing chamber 11, multiple sets of stirring blades 117 are provided on the outer wall of the third rotating shaft 116 to thoroughly mix the sludge and the curing agent. In addition, to enhance the mixing effect, adjacent stirring blades 117 can be arranged in a cross pattern to further improve the mixing effect.

[0034] A servo motor 118 is provided at the top of the tank body 1, and the output end of the servo motor 118 is connected to the first rotating shaft 111.

[0035] Specifically, a servo motor 118 is provided to power the first rotating shaft 111, thereby causing the second rotating shaft 114 and the third rotating shaft 116 to rotate.

[0036] A drug inlet pipe 4 is provided on the side wall of the tank body 1. One end of the drug inlet pipe 4 extends into the pretreatment tank 12. A jet pump 41 is provided on the drug inlet pipe 4.

[0037] In order to smoothly introduce the curing agent into the pretreatment box 12 through the inlet pipe 4, the jet pump 41 is used to provide power for the transport of the curing agent. The jet pump 41 is existing technology and will not be discussed in detail here.

[0038] The conveyor box 13 is equipped with a conveyor 131 located below the conveyor channel 122.

[0039] A conveyor 131 is installed below the conveying channel 122, through which the crushed sludge and solidifying agent enter.

[0040] When conveying within the conveyor box 13, the sludge and solidifying agent can be initially mixed during transportation due to the action of the conveyor 131. In addition, the setting of the conveyor 131 can increase the time of the sludge and solidifying agent in the tank 1, which is beneficial to the solidification of the sludge. In actual use, the conveyor 131 can be conveyed by an auger conveyor.

[0041] The bottom of the conveyor box 113 is provided with a placement cavity 114, and a drive motor 132 is provided inside the placement cavity 114.

[0042] In order for the conveyor 131 to work, a drive motor 132 is provided to drive the conveyor 131. The drive motor 132 is placed in the placement cavity 114 to facilitate the protection of the drive motor 132.

[0043] Multiple sets of support frames 2 are provided at the bottom of the tank body 1.

[0044] Among them, the support frame 2 is used to support the tank 1.

[0045] The tank body 1 is provided with a discharge pipe 5 on its outer wall and a liquid inlet pipe 6 at its top.

[0046] The discharge pipe 5 is used to discharge the sludge, which is fully mixed with the curing agent, from the tank 1 and fill it into the intertidal zone. The liquid inlet pipe 6 is used to introduce clean water when rinsing the tank 1 after the sludge is discharged.

[0047] The working principle of this embodiment is as follows: The sludge conveying pump 3 feeds the sludge to be solidified from the intertidal zone into the pretreatment tank 12. The servo motor 118 is started to drive the first rotating shaft 111 to rotate. The rotation of the first rotating shaft 111 drives the main bevel gear 112 to rotate, which in turn drives the first driven bevel gear 113 to rotate. This causes the second rotating shaft 114 to drive the blade 121 to break up the sludge in the pretreatment tank 12. Subsequently, the jet pump 41 uses the injection pipe 4 to feed the solidifying agent into the pretreatment tank 12. The sludge and solidifying agent then react to form a solidifying agent. The curing agent falls into the conveyor 131 through the conveying channel 122 for preliminary mixing. After preliminary mixing, it enters the mixing chamber 11. While the first rotating shaft 111 rotates, the first driven bevel gear 113 drives the second driven bevel gear 115 to rotate, which in turn drives the third rotating shaft 113 and the stirring blade 117 to rotate, so as to fully mix the sludge and the curing agent. After the curing agent is fully mixed in the sludge, it is discharged from the tank 1 through the discharge pipe 5 and filled into the intertidal zone.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
