Description

Technical Field

[0001] The utility model relates to the technical field of pickling tanks, in particular to a hot-dip galvanizing pickling tank for steel structural parts. Background Art

[0002] When pickling, steel structures are usually lifted into the pickling tank by a movable hook and soaked for a period of time. Then the hook is lifted to suspend the steel structure at the upper end of the pickling tank in order to drain the pickling liquid on its surface. This method takes a long time and has a low draining efficiency.

[0003] In order to solve the problem of low drainage efficiency after pickling, various means have been adopted in the prior art. For example, the Chinese utility model patent with application number 202322144578.1 is a hot-dip galvanized pickling tank, which starts the vibration motor to vibrate the fixed plate, and then the bottom mounting frame of the fixed plate and the placement frame vibrate together, so that the pickling liquid remaining on the hot-dip galvanized surface in the placement frame drips into the pickling tank body during the vibration process.

[0004] In view of the above-mentioned prior art, the inventor believes that when the pickling liquid is shaken off by a vibration motor, the pickling liquid will splash everywhere, which is not only difficult to clean but also may splash onto the on-site workers. Therefore, the existing pickling tank needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 The specific implementation modes of the present utility model are further described in detail.

[0023] Embodiment 1

[0024] The present embodiment discloses a hot-dip galvanizing pickling tank for steel structural parts, comprising a tank body 1 and a hanging component 2 arranged on the tank body 1, wherein the hanging component 2 is connected to the steel structural part through a hanger 21, and the hanger 21 is provided with a vibration structure, which can be a vibration motor, and the steel structural part is connected to the hanging component 2 through the hanger 21, and the vibration structure 3 on the hanger 21 can generate vibration and transmit it to the steel structural part. The above structures are all existing common pickling tank structures, so in this embodiment, no detailed description is given, and the key improvements of this embodiment are:

[0025] Two cavities 11 are embedded on both sides of the trough body 1, and two shielding members 4 for blocking both sides of the mouth of the trough body 1 are vertically movably provided in the two cavities 11. Usually, in order to ensure the efficiency of pickling, a plurality of trough bodies 1 of the pickling tank are provided, and in order to save space, the trough bodies 1 of the pickling tank are arranged side by side. In this embodiment, the trough body 1 has cavities 11 on both sides to accommodate the shielding members 4, which will not interfere with the trough bodies 1 next to it, and will not cause any obstruction when the suspension component 2 moves. When in use, the shielding member 4 is moved out of the cavity 11 and shielded on both sides of the mouth of the trough body 1. In this way, when the vibration motor is used, the pickling liquid will not splash everywhere.

[0026] The shielding member 4 is connected to the bottom of the cavity 11 by a lifting mechanism 5 , and the lifting mechanism 5 is provided to drive the shielding member 4 to move out of or into the cavity 11 .

[0027] Two baffles 12 are fixed at both ends of the tank body 1. The two baffles 12 can provide shielding from the ends of the tank body 1. When the two shielding members 4 are moved upward, they can form a relatively closed space with the two baffles 12 to prevent the pickling liquid from scattering around.

[0028] Please refer to Figure 4 In this embodiment, the shielding member 4 is a straight plate 41a, which is vertically slidably connected in the cavity 11 and is transmission-connected to the lifting mechanism 5. The baffle 12 is a rectangular structure. When in use, the two straight plates 41a move upward and block both sides of the mouth of the trough body 1, and the two rectangular baffles 12 form a shielding space that is closed on all sides at the upper end of the trough body 1.

[0029] The lifting mechanism 5 is any one of an electric cylinder and a motor screw mechanism.

[0030] An air blowing head 6 is provided on the inner side of the shielding member 4, and the air blowing head 6 is externally connected to an air pump 61. When the air pump 61 is working, high-pressure gas is blown toward the surface of the steel structure through the air blowing head 6, thereby accelerating the process of draining the residual pickling liquid on the surface of the steel structure.

[0031] Embodiment 2

[0032] The present embodiment discloses a hot-dip galvanizing pickling tank for steel structural parts, and its structure is substantially the same as that of the first embodiment, except that: the shielding member 4 comprises a sliding block 41b and a shielding plate 42b rotatably mounted on the sliding block 41b, the sliding block 41b is transmission-connected to the lifting mechanism 5, the baffle 12 is a triangular structure, and the shielding plate 42b is provided with a guide structure 421b, and the guide structure 421b causes the shielding plate 42b to move inward when the shielding plate 42b slides out of the cavity 11. Compared with the first embodiment, after the shielding plate 42b moves upward and moves closer, the caliber exposed at its upper end is smaller, which is more suitable for the case of wire rope suspension.

[0033] Please refer to Figure 2 In this embodiment, the guide structure 421b includes a gear 421b1 fixed on the rotating shaft of the baffle plate 42b and a tooth plate 421b2 fixed on one side of the mouth of the cavity 11 and corresponding to the gear 421b1. The lifting mechanism 5 drives the sliding block 41b to move upward. When the gear 421b1 contacts the tooth plate 421b2, the gear 421b1 drives the baffle plate 42b to rotate. A gap is left at the upper end of the closed baffle plate 42b. When a steel structure is suspended using a wire rope or the like, the gap can allow the wire rope to pass through.

[0034] Embodiment 3

[0035] Please refer to Figure 3 This embodiment discloses a hot-dip galvanizing pickling tank for steel structural parts, and its structure is roughly the same as that of the second embodiment, except that: the guide structure 421b includes a counterweight block 421b3 fixed to the inner side of the upper end of the baffle plate 42b, and the lifting mechanism 5 drives the sliding block 41b to move upward. Under the gravity of the counterweight block 421b3, the baffle plate 42b automatically moves inward.

[0036] When the utility model is in use, the steel structure is hung on the hanging component 2 by the hanger 21, and the steel structure is placed in the tank body 1 for pickling by the hanging component 2. After the pickling is completed, the hanging component 2 lifts the structure upward from the tank body 1, and then drives the shielding component 4 to move upward through the lifting mechanism 5 and forms a relatively closed space at the upper end of the tank body 1, so as to prevent the pickling liquid from splashing everywhere when the vibration mechanism 3 is used.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
