Description

Technical Field

[0001] The utility model relates to the technical field of desulfurizing agent processing, in particular to a screw feeder for a desulfurizing agent production device. Background Art

[0002] Sulfur compounds are generated during oilfield development, mainly including hydrogen sulfide (H2S), mercaptan (RSH), sulfide (RSSR), thiophene sulfur, and S, S 2- 、SO4 2- etc. The presence of a large amount of sulfide will cause severe corrosion to the equipment, pipelines, storage and transportation facilities in the process of oil extraction, gathering and refining, resulting in huge economic losses, and even accidents of worker poisoning due to H2S leakage, which seriously threatens the personal safety of on-site workers. At present, desulfurizers have been successfully applied to oil and gas operations and have achieved good technical results. During the production and processing of desulfurizers, it is necessary to mix a variety of production raw materials in proportion. However, since a variety of production raw materials are powders, they need to be transported centrally through a conveying device before mixing. At present, the best way to transport powder is to use spiral tubes for transportation. Spiral tube transportation can not only prevent the generation of dust, but also realize the pre-mixing of powders and achieve uniform feeding.

[0003] The existing spiral conveying pipe is usually connected to the hopper at the top of one end to realize feeding, and a discharge pipe is set at the bottom of the other end. In this way, the powder material can be transported to the farthest position as much as possible. However, in actual use, since a receiving container is placed under the discharge pipe, it needs to be replaced when it is full. Since the receiving container is heavy when filled with materials, it is usually not convenient to move it. In addition, the discharge pipe at the top continuously discharges materials, which makes it inconvenient for the staff to replace the receiving container, which easily causes leakage. Utility Model Content

[0012] Specifically, both sides of the spiral tube are sealed by end covers, and a linear telescopic device is provided on the end cover close to the discharge slot hole, and the telescopic end of the linear telescopic device passes through the end cover and remains connected with the sleeve.

[0013] According to the technical features described in the previous paragraph, the end covers at both ends of the spiral tube are provided to facilitate the installation of a linear telescopic device, thereby facilitating automatic control of the movement and fixation of the sleeve, facilitating the bottom material connection and also facilitating the replacement of the material connection container.

[0015] According to the technical features described in the previous paragraph, the length of the lower half pipe is set to ensure that when the sleeve moves with the linear telescopic device, its lower half pipe can always block the discharge slot hole to prevent leakage.

[0016] Specifically, a circular arc hole for the lower half pipe to pass through is also opened on the end cover.

[0017] According to the technical features described in the previous paragraph, the arc hole of the end cover is provided to facilitate the movement of the sleeve and prevent the sleeve from rotating at the outer end of the spiral tube.

[0029] As described in the background art, when the existing spiral feeding pipe is used to transport materials, the position of the discharge pipe is fixed, which makes it inconvenient to operate when replacing the material receiving container.

[0030] For the reasons stated above, please refer to the attached Figure 1 and attached Figure 2 , the utility model provides a screw feeder for a desulfurization agent production device, comprising a silo 2, which is arranged on a support frame 1;

[0031] The spiral tube 5 is provided with a rotating screw 10 (attached Figure 4 It can be seen that one end is arranged at the bottom of the silo 2 and is connected thereto, and the other end extends to the outside of the silo 2 and a long strip-shaped discharge slot is provided at the bottom;

[0032] The sleeve 6 is sleeved on the outer end of the spiral tube 5 to keep sliding, and a discharge pipe 9 corresponding to the discharge slot hole is arranged at the bottom of the sleeve 6.

[0033] Please see attached Figure 3 Specifically, a sieve plate 3 is provided inside the silo 2, and any side of the silo 2 is open and a baffle 4 is movably provided at the open end.

[0034] According to the technical features described in the previous paragraph, the sieve plate is provided to prevent some harder impurities from entering the interior of the spiral tube and causing wear to the screw, and the baffle is provided to facilitate opening it to clean the impurities on the sieve plate.

[0035] Specifically, the top end of the baffle 4 is rotatably mounted at the opening of the silo 2 , and the bottom end of the baffle 4 extends to the lower end of the sieve plate 3 and maintains magnetic attraction with the side of the sieve plate 3 .

[0036] According to the technical features described in the previous paragraph, the installation form of the baffle is convenient for fixing and rotating, so that it is convenient to block the material after rotating to the end of the screen plate to prevent overflow, and it is also convenient to scrape out the impurities on the screen plate from the gap between the screen plate and the baffle after rotating upward.

[0037] Specifically, both sides of the spiral tube 5 are sealed by end covers 8 , and a linear telescopic device 7 is provided on the end cover 8 close to the discharge slot hole, and the telescopic end of the linear telescopic device 7 passes through the end cover 8 and remains connected with the sleeve 6 .

[0038] According to the technical features described in the previous paragraph, the end covers at both ends of the spiral tube are provided to facilitate the installation of a linear telescopic device, thereby facilitating automatic control of the movement and fixation of the sleeve, facilitating the bottom material connection and also facilitating the replacement of the material connection container.

[0039] Furthermore, the linear telescopic device can be configured as a telescopic cylinder, an electronic push rod, etc. that are convenient for automatic control.

[0040] Please see attached Figure 5 Specifically, the sleeve 6 includes an upper half tube 6.1 and a lower half tube 6.2, the lengths of both ends of the lower half tube 6.2 are greater than the length of the upper half tube 6.1, the telescopic end of the linear telescopic device 7 is fixed to the end of the upper half tube 6.1, and the discharge pipe 9 is arranged at the bottom of the lower half tube 6.2 corresponding to the upper half tube 6.1.

[0043] According to the technical features described in the previous paragraph, the arc hole of the end cover is provided to facilitate the movement of the sleeve and prevent the sleeve from rotating at the outer end of the spiral tube.

[0044] When the screw feeder is in use, the baffle plate 4 is first rotated to contact the end of the sieve plate 3 and keep it magnetically fixed (because the internal material will have a certain expansion force, a strong magnet or electromagnetic can be used, and the power can be turned off when rotation is required), and then the external drive motor is started to drive the screw 10 to rotate. After the material is placed in the silo 2, the material falls on the sieve plate, and its impurities are blocked on the sieve plate 3. The material passes through the sieve plate 3 and falls into the spiral tube 5. With the transportation of the screw 10, it falls on the lower half pipe 6.2 when it reaches the discharge slot hole, and finally discharged from the discharge pipe 9. When replacing the receiving container, first place the empty receiving container next to the full receiving container. At the same time, a receiving slot plate can be placed between the two containers to prevent leakage. Then start the linear telescopic device 7 to drive the sleeve 6 to move, and keep the discharge pipe 9 corresponding to the empty receiving container.

[0045] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
