Pin-connected panel powder jar
Technical Field
The invention relates to a powder tank, in particular to an assembled powder tank.
Background
The powder material tank is used for storing powder raw materials in mixing equipment such as a concrete mixing plant or a mortar plant and the like, is generally of a steel structure, and is divided into different specifications such as 50 tons, 100 tons, 150 tons, 200 tons, 300 tons and the like according to the weight of the loaded powder.
The powder tank comprises two main components of a tank body and supporting legs, and other accessories such as an ash inlet pipe, a fence ladder stand, a dust collector, a material level meter, a safety valve and the like. The jar body includes 3 parts of tank deck, barrel and cone, and according to the structural style of the jar body, present powder jar mainly has 3 kinds of forms: welded cans, split cans, and Lipp cans. The L ipp tank is limited in application due to the fact that professional equipment is needed to manufacture on site, and at present, welded tanks and assembled tanks are generally adopted.
Welding a tank: the powder tank is formed by welding the tank body with steel plates on the site of installation and use of mixing equipment.
Assembling the tank: the tank body is split into split structures, and the split structures are connected with the formed powder tank through fasteners (bolts) on site.
And (3) Lipp tank: the edges of the thin steel plates are mutually engaged into a molded powder tank through molding equipment.
Although the welding tank is low in technical threshold and easy to construct and operate, the manufacturing period is long, the occupied site is large, manual manufacturing is performed on the site, and the quality is difficult to guarantee. More importantly, the large-sized welding tank cannot be moved together with the mixing equipment and only can be scrapped when the mixing equipment is moved due to the fact that the diameter of the large-sized welding tank is large and the size of the large-sized welding tank exceeds the limit. Therefore, the assembled tank is more and more favored by users.
The assembled tank is divided according to the sheet structure of the tank body, and has a multi-sheet type and a large-sheet type. The barrel body (/ cone) is split in the longitudinal direction and the circumferential direction by the multiple pieces, the number of the split pieces is large, and the field connection workload is large. The large-piece assembled tank generally only carries out circumferential splitting on the tank body (/ cone), namely, the tank body is longitudinally divided into one or two or three blocks, so that the number of the divided pieces is small, the connection is convenient, but the large-piece assembled tank divided piece mode which is generally used in the current market is unreasonable, the manufacturability is poor, and the common rubber plate is adopted as a sealing gasket for sealing and unreliable because the connecting surface is long, rainwater easily seeps into the tank body, so that powder caking is caused.
CN201320132812 and CN201420279142 disclose two large-piece assembled tanks, as shown in fig. 1 and fig. 2 respectively, the former divides the tank body into 4 parts such as tank top 1, cylinder 2, lower cone 6 and small cone 3, the latter divides the tank body into 4 parts such as cone top 1, cylinder 2, lower cone 6 and small cone 3, the two structures are the same and different, the actual manufacturability of the tank body structure is not considered, and the sealing importance is ignored.
