Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage tank technology, and in particular to a storage tank with a sampling mechanism. Background Technology
[0002] Storage tanks are generally large containers or enclosed structures used to store bulk materials such as liquid slurries.
[0003] Most traditional storage tanks have only one single sampling port at the bottom or side of the tank. For materials with density differences and prone to stratification, samples taken from a single location cannot represent the true composition of materials at different depths within the tank. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a storage tank with a sampling mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A storage tank with a sampling mechanism includes a storage tank body. A plurality of downwardly inclined sampling tubes for sampling are arranged sequentially from top to bottom on one side wall of the storage tank body. A sampling chamber is opened in the sampling tube on the side adjacent to the storage tank body, and a movable plug is adapted to slide in the sampling chamber. A screw assembly is rotatably arranged on the side of the movable plug away from the storage tank body through a bearing assembly, and the screw assembly is threadedly connected to the sampling tube. The sampling tube has a feed tube extending vertically downwards at its bottom, and a transparent sampling bottle is threadedly connected to the feed tube below it.
[0006] In addition, a preferred structure is that a limiting ring for limiting the transparent sampling bottle is fixedly sleeved on the upper part of the outer wall of the feeding tube, and the outer wall of the feeding tube is provided with an external thread.
[0007] Furthermore, in a preferred configuration, the inner wall of the opening of the transparent sampling bottle is provided with an internal thread that is adapted to the external thread of the feed tube.
[0008] In addition, a preferred structure is that the screw assembly includes a screw section, one end of which is rotatably connected to the movable plug via a bearing assembly, and the other end of the screw section extends out of the sampling tube and is provided with a handle wheel.
[0009] Furthermore, in a preferred configuration, when the screw assembly rotates so that the movable plug is located in the sampling chamber and away from the tank body, the material in the tank body flows sequentially through the sampling chamber, the discharge pipe, and into the transparent sampling bottle.
[0010] Furthermore, in a preferred configuration, when the screw assembly rotates so that the movable plug is located in the sampling chamber and adjacent to the tank body, and the handwheel is in contact with the sampling tube, the movable plug blocks the inlet of the sampling tube.
[0011] The beneficial effects of this utility model are as follows: In this invention, by using a combination of several sampling tubes at one end of the storage tank body, a screw assembly, a movable plug, a discharge pipe, and a transparent sampling bottle, users can sample materials within a specific depth range inside the storage tank body as needed.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Reference Figure 1-3 A storage tank with a sampling mechanism includes a storage tank body 1. Several downwardly inclined sampling tubes 4 for sampling are arranged sequentially from top to bottom on one side wall of the storage tank body 1. A sampling chamber 41 is opened in the sampling tube 4 near the side of the storage tank body 1. A movable plug 31 is adapted to slide in the sampling chamber 41. A screw assembly 3 is rotatably arranged on the side of the movable plug 31 away from the storage tank body 1 through a bearing assembly. The screw assembly 3 is threadedly connected to the sampling tube 4. A discharge tube 42 extends vertically downward from the bottom of the sampling tube 4. A transparent sampling bottle 2 is threadedly connected to the bottom of the discharge tube 42.
[0016] A limiting ring 422 for limiting the transparent sampling bottle 2 is fixedly sleeved on the upper part of the outer wall of the discharge pipe 42, and the outer wall of the discharge pipe 42 is provided with an external thread. The inner wall of the bottle mouth of the transparent sampling bottle 2 is provided with an internal thread that matches the external thread of the discharge pipe 42. The screw assembly 3 includes a screw part, one end of which is rotatably connected to the movable plug 31 through a bearing assembly, and the other end of the screw part passes through the sampling pipe 4 and is provided with a handle wheel. It is worth noting that the bearing assembly is a sliding bearing or a rolling bearing, the outer ring of which is fixedly connected to the movable plug 31, and the inner ring of which is fixedly connected to the screw assembly 3. A sealing ring is sleeved on the outer circumference of the movable plug 31. The specific structure and working principle of the storage tank body 1 are all existing technologies that are currently publicly available on the market, so they will not be described in detail.
[0017] When the screw assembly 3 is rotated so that the movable plug 31 is located in the sampling chamber 41 and away from the tank body 1, the material in the tank body 1 flows sequentially through the sampling chamber, the discharge pipe 42 and into the transparent sampling bottle 2. This is the sampling state. When the screw assembly 3 is rotated so that the movable plug 31 is located in the sampling chamber 41 and adjacent to the tank body 1, and the handle wheel is in contact with the sampling pipe 4, the movable plug 31 blocks the inlet of the sampling pipe 4. This is the closed and sealed state.
[0018] In this embodiment, under normal conditions, the sampling tube of the storage tank is in a closed and sealed state, that is, the handle wheel is tightly fitted with the end of the sampling tube.
[0019] When it is necessary to take a sample from inside the storage tank 1, a dry, clean, transparent sampling bottle 2 is screwed into the thread at the bottom of the feed tube 42 of the sampling tube at the required sampling height, until the bottle opening is tightly against the limiting ring 422.
[0020] Next, rotate the handle wheel to drive the screw assembly 3 outward, causing its movable plug to retract. The screw, through the bearing assembly, drives the movable plug 31 to slide smoothly away from the tank body within the sampling chamber 41. When the handle wheel can no longer be rotated, the movable plug has retracted to the farthest end of the sampling chamber, opening the material passage. At this time, the material inside the tank body 1 automatically flows into the sampling tube under the action of static pressure and gravity, and sequentially passes through the open sampling chamber 41 and the discharge pipe 42, finally flowing into the transparent sampling bottle 2 below.
[0021] Once the sample volume in the sampling vial reaches the required level, immediately begin rotating the handle wheel in the reverse direction to advance the movable plug. The screw assembly drives the movable plug to slide towards the tank body. As the movable plug advances, its leading edge acts like a piston, scraping residual material from the inner wall of the sampling chamber into the tank, effectively preventing cross-contamination between samples of different levels within the tube. When the handle wheel is rotated to a point where it is tightly fitted against the end of the sampling tube, the movable plug has fully reset, tightly blocking the inlet of the sampling tube.
[0022] After confirming that the seal is closed, unscrew the transparent sampling bottle 2 filled with the sample to complete the sampling operation, and the outer wall of the feed tube can be cleaned in time.
[0023] In this utility model, by using a number of sampling tubes 4 at one end of the storage tank body 1 in conjunction with a screw assembly 3, a movable plug 31, a discharge pipe 42 and a transparent sampling bottle 2, the user can sample materials within a specific depth range inside the storage tank body 1 according to their needs.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
