Description

Technical Field

[0001] This invention relates to the field of oil well cementing construction technology, and in particular to a dust removal device and mixing equipment for dry-mixed materials. Background Technology

[0002] During cementing operations in oil wells, cement is thoroughly mixed with various admixtures and additives in specific proportions to alter the cement's strength, fluidity, and corrosion resistance, meeting the cement's performance requirements. Currently, cement and admixtures are mostly mixed on-site. However, since admixtures and additives are powdery particles, they generate significant amounts of dust during mixing, posing a health risk to workers and polluting the surrounding environment. Furthermore, admixtures and additives can easily clog the mixing equipment's feed inlet. To prevent this, workers must constantly tap the funnel at the feed inlet during mixing, which is time-consuming, laborious, and can damage the funnel, increasing construction costs.

[0003] In existing technologies, a vibrating motor is often installed on a funnel at the feeding port of the mixing tank. The vibrating motor drives the funnel to vibrate, causing the dry mixed material adhering to the inner wall of the funnel to automatically fall off, which avoids clogging of the device and saves labor costs. A dust collection box connected to the mixing tank is also installed, and an exhaust fan is used to draw dust suspended in the mixing tank to the dust collection box to remove dust inside the mixing tank. However, the dust collection box on the existing mixing equipment can only remove dust inside the mixing tank during the mixing process, and cannot remove dust when additives or external materials are injected into the mixing tank. This leaves suspended dust in the air, which still endangers the health of workers and pollutes the surrounding environment.

[0004] Therefore, there is an urgent need for a dust removal device and mixing equipment for dry-mixed materials to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a dust removal device and mixing equipment for dry mixed materials, which can not only prevent dry mixed materials from clogging the feed inlet of the dry mixed material mixing equipment, but also effectively treat the dust at the feed inlet when the dry mixed materials are poured into the dry mixed material mixing equipment, ensuring that the mixing environment is not polluted and the health of the workers is not threatened.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On one hand, a dust removal device for dry mixed materials is provided for treating dust generated during the feeding of dry mixed materials into a mixing equipment. The dry mixed materials can be mixed in a mixing tank of the dry mixed materials mixing equipment, and the mixing tank is provided with a feed inlet. The dust removal device for dry mixed materials includes:

[0008] A vibration generator can be installed at the feed inlet. The vibration generator can vibrate on its own and drive the dry mixed material passing through the feed inlet to vibrate.

[0009] The dust baffle can be installed at the feed inlet and can form an opening with the inner wall of the feed inlet, through which the dry mixed material to be mixed can enter the mixing tank.

[0010] A dust extraction assembly, connected to a dust baffle, is used to extract dust from openings.

[0011] Optionally, the dust baffle includes a dust baffle plate that extends circumferentially along the feed inlet, with an opening formed on the side of the dust baffle plate facing the feed inlet. A dust suction port is provided on the dust baffle plate, and a dust suction assembly is provided at the dust suction port. Dust at the opening enters the dust suction assembly through the dust suction port.

[0012] Optionally, the dust-blocking component includes a dust-blocking box, which is located on the side of the feed inlet away from the mixing tank. The dust-blocking box has a through-hole that communicates with the feed inlet. The opening is formed by the wall of the through-hole and the inner wall of the feed inlet. The dust-blocking box has a suction port that communicates with the through-hole. A dust-collecting component is located at the suction port, and dust at the opening enters the dust-collecting component through the suction port.

[0013] Optionally, the vacuuming assembly includes a vacuum generator and a vacuum hose, with one end of the vacuum hose connected to the vacuum generator and the other end passing through the vacuum inlet. The vacuum generator is used to draw dust from the opening into the vacuum hose.

[0014] Optionally, the vacuum assembly also includes a collection can, with one end of the vacuum hose away from the vacuum inlet connected to the collection can, and a vacuum generator connected to the collection can, which is used to draw dust from the opening into the collection can via the vacuum hose.

[0015] Optionally, a filter is provided at one end of the suction pipe connected to the recycling tank. The dry mixture drawn into the suction pipe enters the recycling tank through the filter. A spray device is provided inside the recycling tank to spray water mist onto the filter.

[0016] On the other hand, a dry-mix material mixing device is provided, including a support, a mixing tank, a feeding hopper, and the aforementioned dry-mix material dust removal device. The mixing tank is disposed on the support and is used for mixing dry-mix materials. The mixing tank is provided with a feeding port. The feeding hopper passes through the feeding port of the mixing tank. The vibration generator of the dry-mix material dust removal device is fixed to the outer wall of the feeding hopper. The dust baffle of the dry-mix material dust removal device is disposed at the feeding hopper, and an opening is formed between the dust baffle and the feeding hopper. The dust collection component of the dry-mix material dust removal device is disposed on the support or the ground.

[0017] Optionally, the dust-blocking component includes a dust-blocking plate that extends circumferentially along the feeding hopper. The dry-mix material mixing equipment also includes multiple support rods that are spaced apart along the extending direction of the dust-blocking plate. One end of each support rod is fixedly connected to a support, and the other end is fixedly connected to the dust-blocking plate.

[0018] Optionally, the dry mixing equipment also includes a connecting component fixed to the support. The connecting component is provided with a connecting hole communicating with the feed inlet. The connecting hole extends vertically, and the pipe of the feeding hopper is inserted into the connecting hole.

[0019] Optionally, the dry mixing equipment also includes a mixing shaft and a mixing drive. The mixing drive is mounted on a support, one end of the mixing shaft is located inside the mixing tank, and the other end is connected to the output end of the mixing drive. The mixing drive is used to drive the mixing shaft to rotate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention provides a dust removal device and mixing equipment for dry-mixed materials. A vibration generator is installed at the inlet, causing the dry-mixed material entering the mixing tank through the inlet to vibrate during its own vibration. This prevents the material from adhering to the inlet and allows it to flow smoothly into the mixing tank, effectively avoiding blockages. Workers no longer need to frequently tap the inlet, saving mixing costs and improving efficiency. An opening is formed between the dust baffle at the inlet and the inner wall of the inlet. When the dry-mixed material is poured into the mixing tank through this opening, a dust suction component connected to the dust baffle removes the dust from the opening. This effectively handles dust when the dry-mixed material is poured into the mixing equipment, preventing dust from entering the working space and ensuring a clean mixing environment and protecting the health of workers.

[0036] Example 1

[0037] like Figure 1 and Figure 2As shown, this embodiment provides a dry mixed material dust removal device 4 for handling dust when feeding dry mixed materials into the mixing equipment. Using this dry mixed material dust removal device 4 can not only prevent dry mixed materials from clogging the feed inlet of the dry mixed material mixing equipment, but also effectively treat the dust at the feed inlet when pouring dry mixed materials into the dry mixed material mixing equipment, ensuring that the mixing environment is not polluted and the health of the workers is not threatened.

[0038] See Figure 1 and Figure 2 The dry mixed material can be stirred in the mixing tank 2 of the dry mixed material mixing equipment. The mixing tank 2 is provided with a feed inlet. The dry mixed material dust removal device 4 includes a vibration generator 41, a dust blocking component and a dust collection component. The vibration generator 41 can be set at the feed inlet. The vibration generator 41 can vibrate on its own and drive the dry mixed material passing through the feed inlet to vibrate. The dust blocking component can be set at the feed inlet and can form an opening 5 with the inner wall of the feed inlet. The dry mixed material to be stirred can enter the mixing tank 2 through the opening 5. The dust collection component is connected to the dust blocking component and is used to suck up the dust at the opening 5.

[0039] The dry-mix material dust removal device 4 provided in this embodiment has a vibration generator 41 installed at the feed inlet. When the vibration generator 41 vibrates, it causes the dry-mix material entering the mixing tank 2 through the feed inlet to vibrate, preventing the dry-mix material from adhering to the feed inlet and allowing it to flow smoothly into the mixing tank 2. This effectively avoids clogging of the feed inlet, eliminating the need for frequent tapping of the feed inlet by workers, saving mixing costs and improving mixing efficiency. An opening 5 is formed between the dust baffle at the feed inlet and the inner wall of the feed inlet. When the dry-mix material is poured into the mixing tank 2 through the opening 5, the dust suction component connected to the dust baffle can suck up the dust at the opening 5. This achieves effective dust treatment when the dry-mix material is poured into the mixing equipment, preventing dust from entering the working space of the mixing equipment and ensuring that the mixing environment is not polluted and the health of workers is not threatened.

[0040] In an optional embodiment, see [link to relevant documentation] Figure 1 and Figure 2The dust baffle includes a dust baffle plate 42, which extends circumferentially along the feed inlet. An opening 5 is formed on the side of the dust baffle plate 42 facing the feed inlet. A dust suction port 421 is provided on the dust baffle plate 42. A dust suction component is provided at the dust suction port 421. Dust at the opening 5 enters the dust suction component through the dust suction port 421. The dust baffle 42 extends circumferentially along the feed inlet. When the dry mixed material to be mixed is poured into the opening 5 on the side of the dust baffle 42 facing the feed inlet, the dust baffle 42 can prevent the dry mixed material from falling around the feed inlet, thus preventing the dry mixed material from entering the working space of the dry mixed material mixing equipment. This ensures that the mixing environment is not polluted and the health of the workers is not threatened. The dry mixed material falling onto the dust baffle 42 can enter the feed inlet under the resistance of the dust baffle, improving the utilization rate of the dry mixed material when it is poured into the dry mixed material mixing equipment and ensuring the use effect of the dry mixed material after mixing. The dust suction component is set at the dust suction port 421, which can effectively suck up the dust suspended at the feed inlet and the dust falling around the opening 5 after the dry mixed material is poured into the dry mixed material mixing equipment, further preventing the dry mixed material from entering the surrounding working space.

[0041] In another optional embodiment, the dust-blocking component includes a dust-blocking box disposed on the side of the feed inlet away from the mixing tank 2. The dust-blocking box has a through-hole that communicates with the feed inlet. An opening 5 is formed by the wall of the through-hole and the inner wall of the feed inlet. The dust-blocking box has a suction port 421 communicating with the through-hole. A dust-collecting assembly is disposed at the suction port 421, allowing dust at the opening 5 to enter the suction assembly through the suction port 421. The dust-blocking box ensures that the dry-mixed material to be mixed can only enter the feed inlet through the through-hole, effectively preventing dust from suspending everywhere when the dry-mixed material is poured into the mixing equipment. Furthermore, by connecting the through-hole of the dust-blocking box with the suction port 421, dust is further prevented from entering the working space of the dry-mixed material mixing equipment, ensuring that the mixing environment is not polluted and the health of the workers is not threatened.

[0042] Optionally, see Figure 1 and Figure 2 The vacuuming assembly includes a vacuum generator (not shown in the figure) and a vacuum hose 43. One end of the vacuum hose 43 is connected to the vacuum generator, and the other end passes through the vacuum port 421. The vacuum generator is used to draw dust from the opening 5 into the vacuum hose 43. When the vacuum generator is turned on, a negative pressure is generated inside the vacuum generator, that is, the air pressure at the end of the vacuum hose 43 connected to the vacuum generator will be less than the air pressure at the end of the vacuum hose 43 passing through the vacuum port 421, so that the dust at the opening 5 can be drawn into the vacuum hose 43.

[0043] For example, the dust generator is a fan, and the dust at the opening 5 can be sucked into the dust suction pipe 43 by the suction of the fan.

[0044] In this embodiment, the dust collection assembly also includes a collection tank. The end of the suction pipe 43 away from the suction port 421 is connected to the collection tank. A dust generator is connected to the collection tank and is used to suck the dust at the opening 5 into the collection tank via the suction pipe 43. When the dust generator is working, it can create a negative pressure inside the collection tank to suck up the dust at the opening 5. This not only allows for the recycling of dust formed by the dry-mixed material but also prevents the sucked-up dust from entering the working space of the dry-mixed material mixing equipment, further preventing dust pollution of the mixing environment and threats to the health of workers.

[0045] Furthermore, a filter element is installed at the end of the suction pipe 43 connected to the recovery tank. Dust drawn into the suction pipe 43 enters the recovery tank through the filter element. The recovery tank is equipped with a spray assembly, which sprays water mist onto the filter element. After being sprayed by the water mist from the spray assembly, the dust entering the recovery tank through the filter element will change from powder particles into larger solids. The solidified dust will settle under gravity, preventing dust from re-entering the opening 5 after the dust generator stops working. The filter element can filter out large particles in the dust, preventing larger particles from entering the recovery tank and clogging it.

[0046] Specifically, the filter element is a filter screen with multiple filter holes. Due to the size limitation of the filter holes, only particulate dust can pass through the filter holes, while larger particles cannot pass through, ensuring the normal operation of the recycling tank. The spray assembly includes a water pump, an inlet pipe, and spray nozzles. The water pump is fixed to the tank wall of the recycling tank, and the water pump and spray nozzles are connected by the inlet pipe. The spray nozzles are located above the filter element, allowing water mist to be sprayed evenly onto the filter element from top to bottom, providing good dust suppression and rinsing effects.

[0047] Example 2

[0048] like Figure 1 and Figure 2As shown, this embodiment provides a dry-mix material mixing device, including a support 1, a mixing tank 2, a feeding hopper 3, and a dry-mix material dust removal device 4 as described in Embodiment 1. The mixing tank 2 is disposed on the support 1 and is used for mixing dry-mix materials. The mixing tank 2 is provided with a feeding port. The feeding hopper 3 passes through the feeding port of the mixing tank 2. The vibration generator 41 of the dry-mix material dust removal device 4 is fixed to the outer wall of the feeding hopper 3. The dust blocking component of the dry-mix material dust removal device 4 is disposed at the feeding hopper 3, and an opening 5 is formed between the dust blocking component and the feeding hopper 3. The dust suction component of the dry-mix material dust removal device 4 is disposed on the support 1 or the ground. The feeding hopper 3 is designed to facilitate the pouring of the dry mixed material to be mixed into the mixing tank 2 by the workers. The feeding hopper 3 is installed through the feed inlet, so that the dry mixed material to be mixed can directly enter the mixing tank 2 through the feeding hopper 3. When the vibration generator 41 drives the feeding hopper 3 to vibrate, the dry mixed material passing through the feeding hopper 3 will not adhere to the hopper wall of the feeding hopper 3, so that the feed inlet will not be blocked. The dry mixed material entering the mixing tank 2 through the feed inlet can be mixed in the mixing tank 2 so that the dry mixed material obtained after mixing can meet the requirements of cementing construction.

[0049] In this embodiment, see Figure 1 and Figure 2 The vibration generator 41 includes a housing, a rotor shaft and a motor mounted on the housing. The housing is fixed to the outer wall of the feeding hopper 3. The output end of the motor is connected to the rotor shaft, and eccentric blocks are provided at both ends of the rotor shaft. Specifically, while the dry mixed material is poured into the mixing tank 2, the motor is turned on. The motor drives the rotor shaft to rotate, and the rotor shaft drives the eccentric blocks to rotate at high speed. The centrifugal force generated by the rotation of the eccentric blocks causes the housing to vibrate, which in turn causes the feeding hopper 3 connected to the housing to vibrate. At this time, the dry mixed material passing through the feed inlet will not adhere to the inner wall of the feeding hopper 3 under the action of vibration.

[0050] Furthermore, the support 1 includes an installation platform 11, with the mixing tank 2 located below the installation platform 11. The installation platform 11 has an installation hole, through which the pipe of the feeding hopper 3 passes sequentially. The dry mixing equipment also includes a first elastic element and a second elastic element. The first elastic element is constrained between the feeding hopper 3 and the installation platform 11, and the second elastic element is constrained between the installation platform 11 and the mixing tank 2. When the vibration generator 41 drives the feeding hopper 3 to vibrate, the first and second elastic elements can deform under the influence of the feeding hopper 3, reducing the vibration of the installation platform 11 and the mixing tank 2, preventing the feeding hopper 3 from causing vibration of the installation platform 11 and the mixing tank 2, and ensuring the stability of the mixing tank 2 installation.

[0051] For example, the feeding hopper 3 is a funnel, and both the first elastic element and the second elastic element are springs.

[0052] Furthermore, the support 1 also includes four pads 13 and four support legs 12. The mounting platform 11 is a flat plate structure with a rectangular cross-section. The four support legs 12 are located at the four corners of the mounting platform 11. The four pads 13 correspond one-to-one with the four support legs 12. The support legs 12 are mounted on the ground through the pads 13.

[0053] In this embodiment, see Figure 1 and Figure 2 The dust-blocking component includes a dust-blocking plate 42, which extends circumferentially along the feeding hopper 3. The dry mixing equipment also includes multiple support rods 6, which are spaced apart along the extending direction of the dust-blocking plate 42. One end of the support rod 6 is fixedly connected to the support 1, and the other end is fixedly connected to the dust-blocking plate 42 to fix the dust-blocking plate 42 on the support 1.

[0054] Optionally, see Figure 1 and Figure 2 The dry mixing equipment also includes a connecting component 7 fixed to the support 1. The connecting component 7 is provided with a connecting hole communicating with the feed inlet. The connecting hole extends vertically, and the tube of the feeding hopper 3 is inserted into the connecting hole. When the feeding hopper 3 vibrates, the wall of the connecting hole can limit the horizontal vibration range of the feeding hopper 3, so that the tube of the feeding hopper 3 can only vibrate within the connecting hole. The connecting hole can also support the feeding hopper 3 vertically, preventing the feeding hopper 3 from falling off the feed inlet.

[0055] In this embodiment, see Figure 1 and Figure 2 The connecting component 7 includes a steel pipe 71 and two flanges 72. The two flanges 72 are respectively located at both ends of the steel pipe 71 and welded to the steel pipe 71. The inner hole of the steel pipe 71 is the connecting hole. The flange 72 located at the bottom of the steel pipe 71 is fixedly connected to the mounting platform 11, and the flange 72 located at the top of the steel pipe 71 can support the hopper 3. The steel pipe 71 extends a certain length along the extension direction of the pipe of the hopper 3, thereby supporting the hopper 3.

[0056] Optionally, the dry mixing equipment also includes a mixing shaft and a mixing drive. The mixing drive is mounted on the support 1. One end of the mixing shaft is located inside the mixing tank 2, and the other end is connected to the output end of the mixing drive. The mixing drive is used to drive the mixing shaft to rotate, thereby rotating the dry mixing material inside the mixing tank 2 and achieving full mixing of the dry mixing material.

[0057] In this embodiment, a plurality of stirring rods are provided on the stirring shaft, and the stirring rods are arranged perpendicular to the stirring shaft to increase the stirring effect of the stirring shaft.

[0058] For example, the stirring drive is a motor.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
