Description

Technical Field

[0001] The utility model relates to the technical field of pre-baked anode production, in particular to a suction port device of a suction hoist for pre-baked anodes. Background Art

[0002] During the roasting production process of pre-baked anodes, the important filler suction equipment is the suction hoist. The working principle of the suction hoist is to reduce the air pressure inside the suction port by means of an induced draft fan, so as to form a pressure difference between the suction port and the material, generating an adsorption force. However, the existing suction ports of suction hoists are generally designed as ordinary rectangles. Due to the structure of the suction hoist itself and the deformation of the furnace wall after long-term operation, the original suction port of the suction hoist cannot fully meet the requirements of the suction operation, and cannot fully adsorb the fillers at the edges and top of the furnace box. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a suction port device of a suction hoist. Through a rotary joint, the auxiliary suction pipe can rotate 180° along the main suction pipe to perform suction work on the furnace walls in two length directions. When the auxiliary suction pipe rotates 90° forward or backward along the main suction pipe, it can effectively suck the fillers at the bottoms of the two furnace walls in the width direction. The bent suction socket can avoid the situation where the bottom of the furnace wall cannot be sucked due to the deformation of the furnace wall.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A suction port device of a suction hoist includes a main suction pipe and an auxiliary suction pipe. The main suction pipe and the auxiliary suction pipe are connected to each other through a rotary joint. A rotary joint is installed at the bottom end of the auxiliary suction pipe, and a suction socket with a square cross-section and a bend is installed at the bottom end of the rotary joint. The suction socket and the auxiliary suction pipe are fixed through a connecting piece.

[0006] Preferably, the connecting piece includes fixing ears. Fixing ears are respectively arranged on two opposite sides of the auxiliary suction pipe. Connecting blocks are arranged at the tops of two opposite sides of the suction socket. A V-shaped pull rod is installed between the connecting blocks on two opposite sides. The V-shaped angle of the pull rod is hung on the fixing ears.

[0007] Preferably, the inner diameter of the suction socket is adapted to the outer diameter of the bottom end of the rotary joint, and the bottom end of the rotary joint is inserted into the upper end of the suction socket.

[0008] Preferably, an annular limiting block is arranged on the upper side inside the suction socket, and the bottom end of the rotary joint abuts against the upper end of the limiting block.

[0009] Preferably, a shock pad is provided at the upper end of the limit block, and a gasket is provided between the main suction pipe and the secondary suction pipe.

[0010] Preferably, a through hole is provided at one end of the fixed ear away from the secondary suction pipe, a lifting ring is installed in the through hole, and the end with a V-shaped angle of the connecting rod is arranged close to the secondary suction pipe.

[0011] Preferably, the upper end of the adapter is adapted to the shape of the lower end of the secondary suction pipe, the upper end of the adapter is detachably connected to the lower end of the secondary suction pipe, and the lower end of the adapter is adapted to the shape of the upper end of the suction socket.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The structure of the present utility model is simple. Through the rotary joint, the secondary suction pipe can be rotated 180° along the main suction pipe to perform the suction operation on the furnace walls in two length directions. When the secondary suction pipe is rotated 90° forward or backward along the main suction pipe, it can effectively suck the bottom of the two furnace walls in the width direction. The bent suction socket can avoid the situation that the bottom of the furnace wall cannot be sucked due to the deformation of the furnace wall. And during the whole suction process, only the secondary suction pipe needs to be rotated, which can ensure that the device can effectively suck the bottom of the whole furnace wall.

[0014] 2. There are two connecting rods with a V-shaped structure above the suction socket of the device. The two ends of the connecting rod are respectively connected to the adapted connecting blocks on the opposite side surfaces of the suction socket. The V-shaped angle of the connecting rod faces upward above the suction socket, and the V-shaped angle of the connecting rod is hung on the fixed ear on the side surface of the secondary suction pipe, realizing the installation of the suction socket on the adapter, which is convenient for the installation, disassembly, maintenance, repair, etc. of the suction socket, and improves the practicability of the device.

[0015] 3. When the adapter is inserted into the suction socket, the bottom end of the adapter abuts against the limit block in the suction socket, and cooperates with the external connecting rod, which can ensure the stability of the suction socket installed on the adapter, and avoid the suction socket shaking and falling off the adapter when it collides with the furnace wall or the top of the furnace chamber during the suction operation.

[0016] 4. The shock pad of the device can avoid the impact on the limit block caused by the adapter when the suction socket abuts against the outside, and the shock pad can play a protective role for the limit block and has a certain sealing property. And a gasket is provided between the main suction pipe and the secondary suction pipe, which can ensure the airtightness of the device when the main suction pipe and the secondary suction pipe rotate, and effectively suck the filling material.

[0017] 5. The auxiliary suction pipe of this device is installed on the suction hoist by the lifting ring on the fixed ear. This not only can avoid all the pulling forces on the auxiliary suction pipe acting on the rotary joint and disperse the pulling force on the rotary joint, but also can prevent the V-shaped angle of the connecting rod from falling off the fixed ear, ensuring the stability of the suction socket head.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] A suction port device for a suction hoist, the structure is as Figures 1 - 4 shown, including a main suction pipe 1 and an auxiliary suction pipe 2. The main suction pipe 1 and the auxiliary suction pipe 2 are connected to each other through a rotary joint 6. A rotary joint 3 is installed at the bottom end of the auxiliary suction pipe 2, and a suction socket head 4 with a square cross-section and a bend is installed at the bottom end of the rotary joint 3. The suction socket head 4 and the auxiliary suction pipe 2 are fixed through a connecting member.

[0026] When it is necessary to suck materials from the bottom of the furnace wall, the auxiliary suction pipe 2 rotates on the main suction pipe 1 through the rotary joint 6, so that the suction sleeve head 4 with a square bottom cross-section and a bend rotates, making the length square of the suction sleeve head 4 match the length direction of the furnace wall. Driven by the suction crane, with the mutual cooperation of the external suction fan and the suction sleeve head 4, the bottom of the furnace wall in the length direction is fully sucked. The bent suction sleeve head 4 can ensure that there is a certain distance between the main suction pipe 1, the auxiliary suction pipe 2 and the adapter 3 and the furnace wall, while the bottom of the suction sleeve head 4 can abut against the furnace wall, avoiding the situation that the suction sleeve head 4 cannot fully suck the bottom of the furnace wall due to the deformation of the furnace wall. When the suction work on the bottom of one side of the furnace wall is completed, under the action of the rotary joint 6, the auxiliary suction pipe 2 can be rotated 180° along the main suction pipe 1 to carry out the suction work on the furnace wall in the other length direction. When the auxiliary suction pipe 2 is rotated 90° forward or backward along the main suction pipe 1, the bottoms of the two furnace walls in the width direction can be effectively sucked. The bent suction sleeve head 4 can avoid the situation that the bottom of the furnace wall cannot be sucked due to the deformation of the furnace wall, and only the auxiliary suction pipe 2 needs to be rotated during the whole suction process, ensuring that the device can effectively suck the bottom of the whole furnace wall;

[0027] When it is necessary to suck materials from the top of the furnace chamber, the length direction of the suction sleeve head 4 is rotated through the rotary joint 6 to be parallel to the width direction of the top of the furnace chamber. Driven by the suction crane, the suction sleeve head 4 moves along the length direction of the furnace chamber, and the suction work on the top of the furnace chamber can be quickly completed.

[0028] The connecting piece includes fixed ears 8. Fixed ears 8 are respectively arranged on the opposite sides of the auxiliary suction pipe 2. Connecting blocks 9 are arranged on the tops of the opposite two side surfaces of the suction sleeve head 4.

[0029] There are two V-shaped connecting rods 7 arranged above the suction sleeve head 4. The two ends of the connecting rod 7 are respectively connected to the matching connecting blocks 9 on the opposite side surfaces of the suction sleeve head 4. The V-shaped angle of the connecting rod 7 faces upward of the suction sleeve head 4, and the V-shaped angle of the connecting rod 7 is hung on the fixed ear 8 on the side surface of the auxiliary suction pipe 2, realizing the installation of the suction sleeve head 4 on the adapter 3, which is convenient for the installation, disassembly, maintenance or repair of the suction sleeve head 4, etc., and improves the practicability of the device.

[0030] The inner diameter of the suction sleeve head 4 is adapted to the outer diameter of the bottom end of the adapter 3, and the bottom end of the adapter 3 is inserted into the upper end of the suction sleeve head 4. An annular limiting block 10 is arranged on the upper side inside the suction sleeve head 4, and the bottom end of the adapter 3 abuts against the upper end of the limiting block 10.

[0031] When the adapter 3 is inserted into the suction sleeve 4, the bottom end of the adapter 3 abuts against the limiting block 10 inside the suction sleeve 4 and cooperates with the external pull rod 7, which can ensure the stability of the suction sleeve 4 installed on the adapter 3 and prevent the suction sleeve 4 from colliding with the furnace wall or the top of the furnace chamber during the suction operation, resulting in the shaking of the suction sleeve 4 and falling off from the adapter 3.

[0032] A shock pad is provided at the upper end of the limiting block 10, and a sealing pad is provided between the main suction pipe 1 and the secondary suction pipe 2.

[0033] The shock pad can prevent the impact of the adapter 3 on the limiting block 10 when the suction sleeve 4 abuts against the outside, protect the limiting block 10, and have a certain sealing property. A sealing pad is provided between the main suction pipe 1 and the secondary suction pipe 2, which can ensure the airtightness of the device and effectively suck the filling material when the main suction pipe 1 and the secondary suction pipe 2 rotate.

[0034] A through hole is provided at one end of the fixed ear 8 away from the secondary suction pipe 2, and a lifting ring 5 is installed in the through hole. One end of the pull rod 7 with a V-shaped angle is arranged close to the secondary suction pipe 2.

[0035] The secondary suction pipe 2 is installed on the suction traveling crane through the lifting ring 5 on the fixed ear 8, which can not only prevent all the pulling forces on the secondary suction pipe 2 from acting on the rotary joint 6 and disperse the pulling force on the rotary joint 6, but also prevent the V-shaped angle of the pull rod 7 from falling off the fixed ear 8 and ensure the stability of the suction sleeve 4.

[0037] On the basis of Embodiment 1, the upper end of the adapter 3 is adapted to the shape of the lower end of the secondary suction pipe 2, and the upper end of the adapter 3 is detachably connected to the lower end of the secondary suction pipe 2. The lower end of the adapter 3 is adapted to the shape of the upper end of the suction sleeve 4.

[0038] Even for the same manufacturer, different specifications of roasting furnaces may be designed according to the order requirements of different customers or specific technical requirements. According to the actual size of the roasting furnace, the detachable adapter 3 and suction sleeve 4 can be replaced to facilitate adaptation to different specifications and sizes of roasting furnaces, further improving the application range of the device.
