Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for a setting machine with uninterrupted exhaust. Background Art

[0002] The stenter is one of the main production and processing machines in the textile industry and is used in large quantities. The stenter is a device that finishes the fabric after textile printing and dyeing. High-temperature heating is required in the stenter. The heating method can be to burn gas or light diesel directly in the stenter, or to use circulating hot oil or steam heating, or to use electric heating. The exhaust gas generated by the stenter generally needs to pass through a waste heat heat exchange device because it contains a large amount of heat. Existing waste heat heat exchange devices, such as a textile stenter waste heat exchange device disclosed in authorization announcement number CN101749976 B, include an exhaust gas inlet, an exhaust gas filter, a finned heat pipe, an air inlet, a high-temperature air outlet, etc.; because the exhaust gas discharged by the stenter contains impurities such as oil and cotton wool, a large amount of impurities such as oil and cotton wool are easily accumulated on the filter screen and the finned tube. When the heat exchange device needs to be cleaned, the stenter needs to be shut down before the cleaning work can be completed, which will affect normal production work. Utility Model Content

[0003] The purpose of the utility model is to provide a waste gas treatment device for a setting machine with uninterrupted exhaust. Two waste gas channels can be formed by two air dampers, filter compartments and two valves, so that one waste gas channel can clean the filter in the other waste gas channel while it is working normally, thereby realizing uninterrupted exhaust, solving the problem in the prior art that the setting machine must be shut down before cleaning can be carried out.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] An uninterrupted exhaust sizing machine waste gas treatment device comprises a smoke exhaust channel and an air intake housing arranged at the front end of the smoke exhaust channel, wherein the air intake housing comprises a "convex" shaped air intake bin and a filter bin connecting the air intake bin and the smoke exhaust channel;

[0006] An air inlet cylinder communicating with the air inlet bin is fixed to the upper end of the air inlet bin, and a pair of air doors are arranged on the left and right inside the air inlet bin; an air vent communicating with the filter bin is formed at each end of the rear side wall of the air inlet bin;

[0007] A pair of first partitions and a pair of second partitions are fixed in the filter chamber. The two first partitions and the two second partitions divide the filter chamber into two filter compartments and an air outlet compartment. Each vent is connected to the corresponding filter compartment; the air outlet compartment is connected to the front end of the smoke exhaust channel;

[0008] An air outlet connecting the filtering compartment and the air outlet compartment is formed on the second partition, and a valve is provided on the air outlet; a detachable filter screen is provided in the filtering compartment, and the filter screen is arranged between the corresponding air outlet and the vent.

[0009] Through the above technical solution, the smoke outlet of the setting machine is connected to the air inlet through a pipe;

[0010] During normal operation, one of the dampers is in a permanently open state, i.e., it is horizontally laid out, and the other damper is in a normally closed state, i.e., it is vertically placed. The valve corresponding to the normally open damper is also normally open, and the valve corresponding to the normally closed damper is also normally closed. This allows for a normally open flue gas passage and a normally closed flue gas passage to be created, and the closed and open states of the two flue gas passages can be switched, allowing one flue gas passage to operate normally while the other is being cleaned.

[0011] The exhaust gas from the setting machine enters the air inlet bin through the air inlet pipe, and then enters the corresponding filtering sub-bin through the normally open damper and the corresponding vent. After being filtered by the filter in the filtering sub-bin, most of the impurities such as grease and cotton wool can be filtered out by the filter; the filtered gas enters the air outlet bin through the normally open valve, and is then discharged through the smoke exhaust channel.

[0012] When the filter of one of the filter compartments needs to be cleaned, the damper and valve corresponding to the filter compartment are closed, and the other damper and valve are opened at the same time. The exhaust gas from the molding machine flows out from the other damper and valve to the exhaust channel, thereby realizing the cleaning of the filter without stopping the machine and exhausting the air continuously.

[0013] The utility model is further configured as follows: the damper is in the shape of a rectangular plate, and the outer walls of the four sides of the damper are formed with protrusions with arc-shaped cross sections, and the protrusions on the four sides of the damper are pressed against the inner wall of the air inlet bin;

[0014] The lower end of the damper is fixed on the damper shaft, and the front and rear ends of the damper shaft are hinged on the side walls of the air intake bin through bearings; the front protruding end of the damper shaft passing through the air intake bin is fixed with a push-pull rod arranged perpendicular to it, and the upper end of the push-pull rod is inserted into the waist-shaped ring, and the waist-shaped ring is inserted into the through hole of the locking seat; the locking seat is fixed on the outer wall of the air intake bin.

[0015] Through the above technical solution, rotating the push-pull rod can drive the damper shaft to rotate, and the damper shaft drives the damper to rotate, thereby realizing the opening and closing of the damper;

[0016] The waist-shaped ring can limit the push-pull rod, thereby achieving the stability of the normally closed state of the damper; at the same time, the waist-shaped ring can be turned in the through hole, which facilitates the locking and releasing of the push-pull rod.

[0017] The utility model is further configured as follows: the valve is in the shape of a rectangular plate and is attached to the outer end surface of the air outlet; one end of the valve is fixed to a valve shaft, and the upper and lower ends of the valve shaft are hinged to the side wall of the filter chamber through bearings;

[0018] The valve shaft passes through the upper protruding end of the filter bin and is fixed with an adjusting rod arranged vertically therewith, and the adjusting rod is provided with an adjusting rod locking seat.

[0019] Through the above technical solution, the valve shaft can be driven to rotate by the adjusting rod, and the valve shaft can drive the valve to separate from the air outlet or cover the air outlet, thereby realizing the opening and closing of the valve.

[0020] The utility model is further configured as follows: the adjusting rod locking seat includes a base fixed on the filter bin, two vertically arranged guide rods are fixed on the base, and arc blocks arranged coaxially with the valve shaft are sleeved on the two guide rods, and protrusions are formed at both ends of the arc blocks, and radial grooves are formed on the protrusions, and the adjusting rod is inserted into one of the radial grooves;

[0021] A plurality of compression springs are clamped between the arc block and the base.

[0022] Through the above technical solution, the radial slot can limit the position of the adjusting rod to prevent it from rotating freely. When the adjusting rod is inserted into different radial slots, the corresponding state of the valve is close to the air outlet or away from the air outlet, thereby maintaining a certain stability in the two states of the valve.

[0023] The utility model is further configured as follows: a stopper is fixed to the upper end of the guide rod, and the stopper is placed in the countersunk hole of the arc block;

[0024] A first chamfer is formed on the inner side of the protrusion.

[0025] Through the above technical solution, the compression spring can provide an upward push force to the arc block, so that the radial groove can tightly press against the adjustment rod;

[0026] The stopper can prevent the arc block from sliding upward;

[0027] The first chamfer can facilitate the adjustment rod to move into the radial groove.

[0028] The utility model is further configured as follows: an openable door is provided on one side of the filtering compartment, and the door faces the filter screen;

[0029] The filter screen is inserted between a plurality of pairs of parallel rectangular blocks, and the rectangular blocks are fixed on the upper side wall or the lower side wall of the filter compartment.

[0030] With the above technical solution, the filter can be taken out by opening the compartment door, thereby facilitating the removal and installation of the filter.

[0031] The utility model is further configured as follows: a second chamfer is formed on the front end of the rectangular block and on one side close to the filter screen;

[0032] There are at least two filters in the same filtering compartment.

[0033] Through the above technical solution, the second chamfer can facilitate the insertion of the filter; and the provision of multiple filter screens can improve the filtering effect.

[0034] The outstanding effects of the utility model are:

[0035] Compared with the existing technology, two exhaust gas channels can be formed through two air dampers, filter compartments and two valves, so that one exhaust gas channel can clean the filter in the other exhaust gas channel while working normally, thereby achieving uninterrupted exhaust, solving the problem in the existing technology that the shaping machine must be shut down before cleaning can be carried out.
